DOHC head swap information...finally

Head swap info:
Compression options

DOHC head swap parts list

2.4 block and Evo head(Misc)

Cams:
Cams Choices

Evo 8 vs JDM Evo8 MR

Cam Selection
Cam selection for turbo setup have been covered. Cam selection for a NA setup has not. Here is a suppose setup:

Min.
260/264 [Stock, Tomei, or Greddy/Blox, HKS, or Jun]
A combination proven in the Mitsu Galant Tuned by AMG.
Degree the intake to 18 open/62 close; degree the exhaust to 63 open/21 close to mimic valve timing of the cams use in the galant tuned by amg. For slightly more top end, mimic the valve timing of the jdm evo 8 mr intake by degreeing it to 17 open/63 close.

268/272 (more like the above just more duration, good for a 2.4L[GSC S1/ Blox, HKS, or JUN]
272/272(the norm)
272/280(max for a street/strip setup)

280/272(probably more race/drag/track; 11.5cr+)
280/280

Advance/retard the cams(usually the exhaust first) to get the most out of them.

Setting cam timing:
Option 1

Option 2

4G69 Info:
*The 4G69 is simply a 4G64 with 87mm bore and a deck height of a 4G63, interesting parts may be use to swap over such as lightened crank, rods, and crankshaft pulley, as well as use of the lower compression height pistons to use with a longer rod to increase the rod ratio thus allowing the 100mm stoke to rev higher. More details inside.
FYI

Transmission
Code: F5M42
Code: F5M51(V6 5 speed manual, MAY bolt to 4G64.
Misc. Tranny Information
Evo 4-7 tranny info
Evo 8 and Evo 8 MR tranny info
4G69 tranny on a 4G94
Comparsion between F5M42 and F5M51
*Theory, the 6G75 6 speed MAY bolt to the 4G64 and MAY/MAYNOT fit into the engine bay. The 6G75 is base off the 6G74 as well the 6G72(3000GT), and the non turbo 3000GT used the same tranny as the FWD turbo Eclipse with different gear ratios.

Headers For N/A Applications
4-2-1
Headers for the G4JS head and 4G63
K-Spec 4-2-1
K-Spec GT
DC Sports 4-2-1
OBX Racing 4-2-1

You can increase the performance of an "interference" 4-2-1 header by installing a crossover pipe (either H or X) near or at the first "y" intersection(i.e. 1-4 and 2-3 section). Read the following articles for more details.
Article 1
Article 2
Header 101

It's also possible to modified the Fed Spec header by adding a taper collector such as a megaphone or adding a crossover pipe.

is it possible to keep cruise control with the DOHC conversion?

FlashBlueRS · 12/28/2007, 11:51 AM

Use the Outlander throttle body instead of the EVO.

cyberbrain · 12/28/2007, 01:53 PM

thanks flash.

crazy_ugly_co · 12/28/2007, 05:00 PM

Is there a confirmation on whether the 300GT tranny will bolt up? Are there and advantages with that gear box?

bluebomber · 01/01/2008, 03:42 PM

I had read somewhere that there are holes that need to be plugged up in the block when doing the swap but from what I can tell it looks like that is not the case. I figured this would be a good place to post this question.

That's only for swaps done on 2G eclipses. Nothing needs to be blocked or plugged with the 3G head swaps.

bluebomber · 01/01/2008, 04:29 PM

Heres another one, If using the 94 galant dohc timing belt do you still need to use adj. cam gears?

Someone mentioned that you won't have to, but his timing appeared to be off. I would get the Evo8 timing belt and gears. It'll allow you to take full advantage of the DOHC head by being able to tune the intake and exhaust independently. Prosteetonline has cam gears at a great price and evo8 timing belts for less than $30 when they are in stock.

I have a question, what about 2000 ECU guys? I know I'm not 2000, but I'd hate not to leave those guys out. Just compile info for them if necessary.

Here's the info I found, not trying to contribute for e-rep, but I think this thread will help.

dou you lose a/c or power steering with the swap

I'm sure others would rather chastise you first, but since this is your first post I'll be nice...

There are actually quite a few threads covering this topic in great detail. Click on the word Search up at the top right and then type in various things you'd like to know about. Searching through the various threads before you ask questions helps us from having to answer the same questions over and over...

In answer to your question though, I wouldn't think so, but I haven't done the swap...which I why I recommend you search to see if that's been covered. I know there is a thread with a complete parts breakdown on what is needed...

4g64t · 01/05/2008, 01:31 PM

yes you can keep your stock power steering and a/c they both bolt up to the block not the head

chino · 01/08/2008, 12:40 AM

4g64t · 01/08/2008, 02:21 AM

nice work on the comparison pictures now people can stop asking that question

mysticj · 01/16/2008, 11:31 PM

did a little revision.

mysticj · 02/09/2008, 12:00 AM

sticky?

mysticj · 02/21/2008, 08:24 AM

Timing Belt & Cam Gears
4G63 = Timing belt will work, a little tight because not engineer for the deck height of a 4G64/G4JS DOHC setup. 4G63 adjustable cam gears is required.
4G64 = Timing belt from the 1994 Galant GS is the perfect match. Made for the deck height of a DOHC 4G64. 1994 Galant GS cam gears or 4G63 adjustable cam gears.
G4JS = Timing belt will work if all the timing components(i.e. cam gears, oil pump gear, etc) from the G4JS is swap to the 4G64. No adjustable cam gears for the G4JS exists.

Stroker kits
Brian Crower offers a stroker for the 4G64 with a DOHC head. For a 2.5L setup, 86.5mm(stock) or 87mm bore with 106mm stroke with a 156mm(est) rods. For 2.6L, same setup as for a 2.5L but with a 87.5mm bore.

malachi · 02/22/2008, 12:08 AM

update on me, ill be starting my swap soon. just have to finish the shopping list. ill try and take as many pics and even Video of the whole process. and do a write up. LOL im only a year behind my finish date.

FlashBlueRS · 02/22/2008, 03:09 AM

I just finished my second DOHC motor build. Nothing too special. Deleted balance shafts and 272/272 BC cams. Very similar to my original motor.

4g64t · 02/23/2008, 03:40 AM

sounds good flash did you build a whole different motor or did you do that stuff to the motor you had in the car?

i've been done with mine for awhile but i'm doing a bunch of other stuff to the car so its not back on the road yet unfortunatly

It's a completely different motor that is going in another car. This one is getting a turbo.

malachi · 02/24/2008, 09:54 PM

dam flash, where are you finding all the parts. iv hit a brick wall getting parts.

What do you need?

malachi · 02/25/2008, 03:11 PM

well, i have the assembled head ( internal), and intake and TB and all the parts for that(including fuel parts)

i need, adjustable cam gears, valve cover, all timing belt covers, spark plug boots.

i believe thats it. pluss gaskets.

the parts list you made confusses me when it comes to the parts for the head, i have the assembled head but i dont know if some of the parts are for the head or not.

ill take some pics of what i have and start a thread to night or tomorrow.

So does this mean that us 2000 guys can't do the swap without running a standalone like AEM EMS? Or could we just swap our ecu for a newer model?

TorqueGS · 02/25/2008, 06:51 PM

No way to make the stock work?

KooIDud3 · 02/25/2008, 07:13 PM

i thought flash mentioned in one of his threads that the stock ecu does well with the swap it just thinks it is still sohc. so i would guess the 2000 ecu would work aswell but i still recommend getting a flashable ecu for tuning to get the most out of the swap.

+1. There shouldn't be too many electrical differences between the two heads, so it should run with a stock ECU, but with the change in compression, you're definitely going to want to be able to modify fuel and ignition tables.

TorqueGS · 02/25/2008, 07:39 PM

Sweet! Thanks.
