The story as it began:
I've had enough people asking me to make a thread and since the mods like to keep things specific I guess I'll round everything up here. I'm not huge into the whole "oh boy look at my shit" stuff but for those into performance and the knitty gritty on this platform, maybe you'll find something useful or at least interesting.

History:
Bought my 3g back on December 19th, 2008 for 6k flat after taxes and fees. Had 83k on it, but it was in rough shape. Needed brakes and tires, eventually a harmonic balancer and belts, both window regulators, a complete rear suspension rebuild, a new clutch, and the usual maintainence stuff. I did the clutch in december which rounded out the last of all these repairs and have enjoyed driving a reliable, well running car for until last wednesday, well almost.

Now:
For those of you who have stuck your head into the performance sections this forum you've probably seen glimpses of what I've been up to. I've done a fair amount of exploration but all of it has been oriented towards a turbo build on a 6g74. Not just any turbo, and not just any 6g74. :naughty: Well, now the time has come. I've got all the parts and the shortblock is due in tomorrow or Friday. I tore into the car last Wednesday, I'm still very busy but its been the focus of daily work so I'm getting places with it. Here's a few shitty pics of what's going on.

I'd also like to mention I'm breaking the motor in NA which is why the turbo stuff isn't relevant just yet.

First thing I decided to do was strip my interior. Its really easy.
Image

Actually I just pulled the seat cushion to put in my Walbro 255, the hatch trim is out because the PO cracked it when he deleted the rear wiper and it rattled enough to end its presence in my car. The install is very simple, just a serious pain in the ass. Since my car is of Iowa origin, the area under the seat was fully of dust from a gravel road which essentially siezed the black ring onto the assembly, as well as 12 years of age. Luckily I got the stinker off and swapped the pumps out. For anyone doing this install a belt sander works 1000x easier then a Dremel for shortening the stock pickup sock. Once back together I let it idle for a couple minutes to make sure it sealed properly, it runs noticeably richer without a real fpr and the stock tune.

Parked it at last. Been working towards this day for 2 years.
Image


First thing I pulled off was the muffler. Stupid thing cracked off the pipe 2 weeks before breakdown day. Stock exhaust minus this and an extra resonator, sounded awesome.
Image


Started the tear down.
Image


Hubs out
Image


Keep on pullin stuff
Image


Drained all the fluids. This being the trans. Fluid was still very clean from the clutch job I did 3k ago.
Image


Ready to pull engine and trans
Image


Stock motor came out easily. I pulled the exhaust manifolds off hoping to find something worth porting and was direly disappointed. The 00 Fed spec manifolds aren't actually cast, they're two halves and two flanges all welded together. There isn't enough metail to actually make them flow worth shit so I have to figure something else out. Might just use the RPW shorties I have. Anywho, the front of my motor has been doused with oil. It saturated even the exhaust gaskets. Can't figure out how it bled so much, the oil cap was always tight and I couldn't believe the valve covers would let this much go with a good clean PCV valve.
Image


Exedy stage 1 clutch, put it in 3k miles ago with a resurfaced stock flywheel. Broke it in properly, it grabbed wonderfully. The machining on the flywheel is still fully visible and feelable and the disc is very healthy.
Image


Out and shoved in the corner until future attention.
Image


Shot of the whole situation.
Image


One of the more irritating tasks... soldering in the IAC pigtail. The one off the 74 harness uses much thicker gauge wire and my heat sinc kept biting through the insulation, not to mention there isn't any good work surface in there. Got her done nicely though, shrink wrapped then wrapped with 3 layers of tape.
Image

Image


The next attention was given to the 6g75 upper manifold. Specific details on it can be found here: http://www.club3g.com/forum/3g-eclipse-gt-gts-specific/142719-75-galant-upper-manifold-swap-thread.html
The final task was fitting the throttle cable to the manifold. I had a bracket premade but of course the adjustment still wasn't enough. I actually simplified it a lot in the end. Just a basic SS L bracket and the 6g74 manifold tb cable bracket bolted onto it. Nice and sturdy too.
Image


Next on the list was/is the ECU. Since I have an 00, I'm fucked for tuning. I have an Emanage ultimate, but I want to give the stock ECU's a run for their money with big maps first. I have an 03 GTS Ecu and a 1.3 cable, already tested them and they work together fine. I pulled the 00 to send out to a friend (Thanks Teyler/Black_Out!) to read for me since he has a 2.0 cable. Once I have that ROM I'm sending it to Acamus for a custom big maps ROM, a knock off of Damian's/02meclipse. Its a late 02 ROM so its the 3 pulse distributor reluctor (Thanks charles and greg) and the 3 bar Evo MDP sensor. Anywho.
Image

Image

Anyone who attempts this should be weary of the main harness. You can tear it when squeezing the ECU out of there and I also warn the bracket its on is sharper then it looks as I got a nice red surprise when thing got tight.

My buddy Connor is my helper on this and he was off doing his own thing for awhile so I took an hour to get started on some of the tedious suspension stuff. Moog endlinks and prothane bushings for the control arms and sway bar is the plan (Front, rear is another story I'll cover later). I cut the links in half then popped them with a 2' break bar just to see how easy it was. The link flexes plenty before it pops but neither are good, they are junk. Come out in about 15 pieces too.
Image


Today, May 25, 2011. Things get real. The engine was out last Thursday but between Rugby and a weekend up north and Connors starter blowing progress slowed. I was pissed, and ready to kick some ass. Went to my shop to kick 'em in the pants to getting my shortblock done. Supposedly it'll be done tomorrow, if not, Friday. He said he'd give me the final price by the end of the day but he never called so I'm going to have to wait til Friday to pick it up anyway. That's fine because I've got plenty to do. After that I went to mitsu and ordered the rollers and speedo gear for the Wavetrac. Between trips I managed this:
Image


Image


Image

Stock pumpkin vs Wavetrac. The Wavetrac is a 12 lb tank. I now understand why people break these things so often (my stocker is officially up for sale). The sun gears are tiny, and worthless. The pin that holds the sun axle in also likes to fall out so I'm surprised people don't throw them more often. There's an awesome thread on the differential stuff here: http://www.club3g.com/forum/3g-eclipse-gt-gts-specific/147925-limited-slip-differential-install.html Thanks to everyone who is and will be helping me and contributing info to that.

Anywho, that's all I got for now. Plan for tomorrow is still a bit up the in air. I'll know better what's next when the engine is home but for tomorrow I'm thinking I'll do the control arm and sway bar bushings and install/grease the Moogs then start wiring up the gauges. The biggest thorn in my side right now is the exhaust. Since I'm going all custom I have to fab it up and get lots of costly materials. Furthermore the fucking o2 sensors are seized in tighter then I knew what to do about so I had to cut them off the car. Still have to get them off the exhaust so I'll have to nuke them with pb blaster and put a big bar and hope they pop. Otherwise its smooth sailing ahead. Differential bits come Monday so I'll zip that up then and hopefully begin assembling the 74. Friday I'm working on the car all day so I'll get as much done then as I can and hopefully get it running sometime late next week.

More pics and stories to come!

:wub: Oh man guys. :lol: I hold no animosity for any other 3ger here except maybe a few of the idiots poluting the forum with their misleaded antics. By that I mean I am in no way competing with anyone, least of all Charles. I have a great respect for what he is doing and have learned through my own endeavors about taking ones time. I have afterall been working on this since June 15th 2009. That day I bought a 6g72, a hoist and a stand and began learning. Honestly I say for any noob starting from zero (and I'm sure some of you remember when I was there) who actually wants to get somewhere and get good with this car, just dive in. There's nothing you can do turning bolts that you can't fix or undo or put back together. Might be stressful, but as long as you don't cut something unreplaceable then you'll make it out fine. Reading is/has taught me the conceptual stuff, but for everything I know about the 3g I got from pulling apart my own car and others. Hands on is the way to go.

Anyway, I wasn't kidding when I said I was going all out on this. Yesterday was huge, here's a few shitty pics of what's going on.

I spent a good 4 hours at the junkyard on Monday looking through suspension setups. I wanted a few parts for my own so I could trade out some bushings ahead of time. Didn't find anything worth pulling, so I went ahead and ripped mine apart anyway. I must comment though, after looking through thousands (literally thousands) of suspension setups I have to compliment the 3g's. Geometrically its a great design, tubular rear arms, rigid geometry, the fault is the soft stock bushings. These things kill the handling of the car, along with a set of soft springs and shocks. However even with the stock springs and struts its extremely improveable. This is how:
Image

Rip the worthless shit out. A full prothane bushing set for our suspension goes for under 200$. If you go for the gold get 2 pairs of GST upper knuckle bushings too to do the upper and lower bushings on the rear knuckles to perfect it (this is what I've done/am doing).

For anyone whose done motor mounts, particularly if they've sleeved them tight, take the difference that gave between stock and apply it to every bushing in the suspension. The difference is astounding.
Image

For those who have the 00 like me, we have a slightly different control arm setup in front then the rest of the years. The big bushing has an outer sleeve but not inner. The peg on the C-arm rids rid on the bushing (other years have an inner sleeve too). This allows the peg to rust and bind up the bushing and tear it up. The small bushing has an inner sleeve but not an outer sleeve so you can press it out and pull the rubber out of cut the entire thing out.

The previous owner did a lot with sound, so there was a lot of wiring that I've been cleaning up. There's one hole in the firewall intend to use for the gauges, of course I may need to make it a bit bigger. The MN rust is killing me, though I'm getting rid of a lot of it.
Image


Back to the C arms. For anyone wanting to do bushings, you don't need a press. It makes life hella easier but the second option is the employment of hole saws. I have 3 sizes that I've done the whole suspenion with. I'll need one more to do the rear upper arms later this month. The trick is at Ace Hardware, their Bi-metal saws are unstoppable and super durable. I've put them through 1.5" of solid aluminum and multiple bushings without issue. Only bit of warning is in any case that the bushing starts to burn or melt, DO NOT BREATHE THE FUMES. It is insanely toxic, it can kill you. That said I've never had an issue.
Image


While doing the control arm bushings it is stupid not to do the front sway bar bushings too. They're a whopping 10$, and I garentee your stocker are shot. I could move my bar all over the place, as well as bend the crap out of the endlinks.
Image


Image


Image

With the prothanes in it is rock solid, I can't wait to drive it. (camara is sidways, the bushing comes out the bottom)

Prothane everything with Moog endlinks freshly installed and greased, all set to go.
Image


My 3 gauge pod was painted silver by the PO, so I went and returned it to black with some Krylon Fushion, very good plastic paint when applied right.
Image

I used this same paint on my bumper inserts 2 years ago and it hasn't chipped or decolored even after 2 winters.

Next task, finishing the injector harness. On GT's the rear harness is a completely seperate entity that you can unplug. I had an extra one so I hacked that up ahead of time, so I had to finish the front now that its high impedence duties are over with.
Image

10 ohm 20 watt resistors bought off amazon. Only get the 20 watt, 10 watt will blow during extended use.

I used to hate wiring and electronics. Now I don't mind at all. I've done probably 6 hours of soldering this week alone.
Image

Resistor goes on the hot/red wire. I'm also switching out the injector clips to run my PT 550's.

Finished product. I taped the resistors to the plastic casing for the time being which is why its so ugly. Once I have the clips on the injectors I'll cut the tape off and place them permanantly in the perfect place so they won't pull on the wires. It'll look nicer too. Everything was shrink wrapped with super nice heat shrink, its a clear kind that melts on the inside when it shrinks so it makes a perfect seal.
Image


For anyone who gets a mishimoto radiator... bring your dremel. The stock fans fit, almost. You'll have to enlarge the holes in the mounting tabs at least a little. I got the drivers fan to bolt up just fine but the bottom 2 mounts on the passenger fan were off so I had to cut it a little. Also, don't be freaked out if a few fins have been brushed when you open it up brand new. Its packaged wonderfully but even though mine was brand spanking new a few fins were mildly tweaked in shipping.
Image


Finished product.
Image


That's all for yesterday's progress. Now I'm off to go pick up the shortblock. Yes, for real, time to pick this mofo up.

Glory.

Image


Image

3.6 liters of fully built V6 goodness. She's being kept sealed under wraps until monday or more likely tuesday when I can give it full attention and can bolt the trans to it right when I'm done assembling. My only fear right now is the valve to piston clearance due to the stage 2 cams. They were specified when ordering and the stock pistons don't actually have reliefs nor do the cams hit so I should be fine. I'll be claying it either way.

The other thing that came home from the shop:
Image

Spec stage 4, to be used with 6 puck unsprung hub and a Fidanza 9 lb flywheel. Why were they at the shop? Getting balanced, that's why. Believe it or not the fhywheel just a smidge off, the pressure plate was a tiny amount off. The assembly has been balanced together so it will spin in perfection. This thing is gonna rev like no tomorrow!

Image


Image

Rest of the engine parts to the garage.

4 jobs left.
1) Assemble transmission. Waiting on parts from dealer which'll come Monday.
2) Pull O2 sensors and make exhaust. Gotta order exhaust parts next week...
3) Assemble engine. Gonna wait until Tuesday to do it all in one shot.
4) Wire up the gauges. This we started today.

Pulled the stock pillar trim and test fitted the pod and gauges.
Image

Unlike most of the interior crap I see people put in, this fits like a glove.

I'm going to wire the gauges in on their own circuit running right off the battery. 10 amp inline fuse and this switch put into the fog light switch trim (I deleted my fogs).
Image


I'm fried so I'm going to take the rest of the afternoon off to be lazy and let this all sink in. And figure out how to wire up all the wideband..
 
#29 ·
No doubt you will be the first person I talk to if they don't work. However I don't see how they can't, the reliefs are deeper then those on the stockers and you can cam the stockers so by logic... That's what I keep telling myself anyway. :lol: I'm getting antsy. I'll probably go start working on it even though I'm supposed to be lazy right now.
 
#32 ·
Oh god, hopefully only once the turbo is in. Though with the balanced clutch and all this lightweight stuff it'll drive unlike anything I've ever driven.

I'm nervous as hell, I've done oils pans and stuff before but RTVing the main seal and oil pump is damn high stakes! Hopefully some pics later tonight.
 
#33 ·
Did mostly house cleaning tonight. I am short one part to start on the gauges and that's a 10 amp inline fuse, once I have that I'll get going on those. As for the motor, I finished dressing the block. Installed new freeze plugs and the oil galley plugs as well. Then put the windage tray on and decided to wait til tomorrow to do the RTVing as I need some new stuff.

Image


Image


Question for the night: is there a gasket that goes between the water pump and its housing? Time to investigate.
 
#37 ·
Went to the yard and grabbed a gasket. 5$ worth of gas and an hour of my time, it was in decent enough shape to use but I cleaned it up a little bit and installed it with some blue permatex to keep things tight. Put in some solid hours today...

Torque specs. Lots of them.
Image


Timing stuff. Getting anxious now!
Image


RTV-ed everything and installed. Oil pump, main seal, upper and lower oil pans.
Image

Lower oil pan was done up with some silver high temp paint.

Water pump in.
Image


All timing components in.
Image

Got a bit frisky and put the PS bracket too soon. Gotta time it and put in the timing covers before that guy.

I spent probably 45 minutes just cleaning stuff. Went through half a roll of shop towels and half a can of brakekleen making sure the decks were 100% spotless.
Image


Installing ARP head studs. Lubricate the threads with ARP moly assembly lube.
Image


Fully dressed. Ready for the heads.
Image


Head ready for installation.
Image


Heads in! Not torqued yet, had to take a dinner break and figure out some misc stuff.
Image

Whenever I'm not working on it it is covered by the bag.

I must thank BJ (boostzealot) for his help. He's been nudging me along through this keeping everything on the right track, I can't thank him enough for his help. I've done timing belts and head gaskets but this is a whole different league.

My current hang up is I don't have a torque wrench that does inch pounds, just foot pounds so I can't rebuild the fidanza's yet with locktite. I have to go to my shop tomorrow for a baleout there. Also need to bleed the lifters so I can install the rockers so I have to pick up a gallon of deisel tonight and find some wire. Once those two jobs are done timing it will be 5 minutes and if the valves clear then its another 10 minutes worth of stuff to install before its ready to drop in. Should be getting the trans stuff tomorrow and I'll zip that back up then its drop in time!
 
#42 ·
Whew, what a day. I put some miles down and got my shit together. At this rate, I might have it fired up sooner then I thought.

Pushed in the cam seals, lubed up the journals and popped this baby in there. Front cam in.
Image

Slid in nicely, its tight but not too tight, perfectly in spec.

One of the big thorns in my side today.
Image

It was half a degree off, and assembled without locktite so I (with BJ's advice in mind) took them apart.

Then I went off and ran 2 hours of errands. Stopped at the shop and picked up 5 quarts of Break In oil and got the gears torqued. Kenny was nice enough to do it for free.
Image

Assembled with red locktite and torqued to 45 inch pounds.

Stopped by the dealer for this business.
Image

GST speedo gear and new rollers for the diff. Fucking dealership didn't even call me to tell me they were in like they said they would. The douchebags.

Finished up the cams and gears. They spin so easily without the rockers in.
Image


Wetted down the wavetrac and tossed it in the freezer.
Image


The fun didn't stop, time to time it at last!
Image


These engine are very easy to time if you pull out the center tensioner, just the roller itself not the rotating bracket. Pull that out and hole the belt over the crank cog, then bring it up and match the teeth over the front bank gear. Move the gear to match the teeth then turn it to make it tight. Then install the belt over the water pump and other gear. Turn the rear gear to match the teeth then crank it back to pull it tight, the only slack will be between the rear gear and the crank, install the center tensioner. I pried it tight with a screw driver and tightened the bolt. 2 sets of hands helps. Pulled the pin on the hydraulic unit effortlessly. Cranked it 10 times and they match perfectly.
Image


Image

Painted the valve covers with VHT Flame Treatment paint. Lots of coats. Lots...

Turned it to TDC and install the distributor with the rotor pointing to cylinder 1, she is set to go.
Image


Then of course I had to go to work. While out I also picked up a half a gallon of deisel to use to bleed the lifters which I'll do tomorrow. Once those are in its the lower manifold, water housing and the accessory bracketry and its ready to bolt to the trans. Gotta reassemble the trans tomorrow too. She's comin' together!
