Bought my first 3G about 3 years ago! Decided i wanted to make my car a little bit faster so I decided to turbo it and head swap it! Definitely not the prettiest 3G but its a running 3G. 

When I first bought the car.

Turbocharging the SOHC motor, stock block at this point.

Kia head swapping the car
Evo 8 head swapping the car
Building the engine with forged internals.
Reassembling the car, at this point is has
Top end:
GSC valve stem seals
Ferrera +1mm valves, super tech valve springs, kelford 272 cams,

Bottom end:Stock crank, eagle H beam rods, CP Carillo forged pistons.

Stock automatic transmission

Fast forward a year, the Evo 8 head is removed, stock bottom end again. Upgraded to a Holset Wh1c turbo(56mm) Kia head (kelford 272).

There's a few things going on with the car at the moment. I want to build another motor for the car before officially hitting the strip.
I plan to use an Evo 9 head I have laying around, coupled with a 2.1 Long rod motor I will build. Will be on E-85 in a week or two. Hopefully the car will see 12s by this summer or perhaps the end of the year, thanks for looking!

Nice to see someone making a Spyder faster...too many people think it's a coupe or nothing. I really like the Spyder's look, and it's a blast driving with the top down!

Yeah I love spyders, super fun to drive with the top down.

Agreed. Had mine for 17 years now. ...J.D.

With your set up 12s should be pretty easy only problem will be the trans that will hinder you from getting to that goal a lot easier. On a stock v6 with a 75 shot of nitrous and basic bolt ons I was already in the mid 13s with all season street tires and open diff. Mind you this was 15 years ago.

Yeah I've driven it a bit, definitely feels like a 12 second car. The switch to E85 went pretty great. But gas mileage sucks and there's only a handful of stations close by. These transmissions are tougher than we give them credit for. Mine is still going strong. Only thing I could possibly see going wrong is the diff giving out.

An LSD and upgraded converter go a long way. Lmk if you need tips on the converter. I also have a new LSD on my shelf I need to sell. You can always PM me here or message me on Facebook.

Updates***12/1/22
After running the car on maf since I've had it. I've finally decided to make the jump to speed density!
Ditched my old recirculating intake. Car idles and drives a whole lot smoother.
Setting up speed density in the tune was a little confusing at first but it turned out to be pretty easy in the end. Instead of using a GM IAT sensor in using the fuel temp to emulate iat so far no issues!

 

[Tprate2]

12/30/22 it was a little warm out today so I did a little bit of work on the car.
Bought a new turbo, dropped the WH1C out, installed my new 60mm holset H1E. Painted my turbo manifold. And retapped my oil pan for a true 3/4 oil I.D return.
I also finally got around to implementing the free fuel flex fuel patch onto my rom. Now I don't need to run an E-85 map and a gas map. I can now run mixtures of both and have the timing interpolate based on the percentage of Ethanol to gasoline.

Going into the new year with a retune for the new turbo. Im hoping to hit 600 WHP @35 psi. although I won't complain with High 500s. Wish me luck!

 

[Tprate2]

Just a little update, still working on the tune, ironing things out and fixing things as I go along. Had a little bit of a mishap today. Was driving along during a pull, then my radiator gave out, it developed a small crack at the very bottom of the radiator and started spraying coolant.

But the engine and the automatic transmission are holding up fine to the boost. Instead of my original goal of 35PSIn on the turbo I'm now hitting 40 PSI.
This should put me at about 500 to the wheels at the least. Hopefully I see more as I turn it up gradually. Then when I'm all done, it'll be time to take it to a real dyno!

 

[Tprate2]

Little update on the build, been boosting along just fine, replaced the radiator after the incident. But decided to take the head off and do a few upgrades for some extra power and added insurance!

Dropped off the head to get cleaned and resurfaced while I had it off, ordered a few new parts since I already had the head off.
Sold off my ARP headstuds and picked up some L19 Head studs. Just a little insurance to minimize the chances of the head lifting.
Also uninstalled my BC272s and upgraded to the more aggressive GSC S2s.
While I had everything apart I applied some heat resistant coating to my intake manifold and fuel rail.
Can't wait to see how the car responds to the new cams in combination with all the boost.
Next up, checking the tune for any modifications I need to make, then it's off to the Dyno,
Super optimistic about hitting 600+ WHP

You aren't running 40 psi on a stock bottom end 4g64 hooked up to a stock 3g auto trans. You aren't making 500whp and you will never make 600whp.

This platform has been around for over 2 decades and many a 4 cylinder auto car have blown up under 250whp because that's just how weak the stock parts are. The Evo 4g63, which is way more stout than your motor, fold rods around 400wtq through a manual and only a few stock Evo engines have survived over 500whp. The F4A42 begins breaking hard parts under 250whp and you don't even have a limited slip differential.

If you were making 500 you would be spinning the tires at 100mph if the trans could even hold it. Take that from somebody whose done it on cars way more set up than yours. The videos of your car are extremely slow and would probably run with bolted on V6's. You just have to use your eyeballs, I don't know what you're doing that makes you think you have all this power and why you're just magically above the mechanical limits that affect the rest of us. Quit purporting these lies and go get a real number on your car. Heck, even a draggy would tell you. 500 will trap 125+ even with the stock auto hanidcaps.

Just getting around to seeing this,I'll address each point one by one.
You don't seem to know very much about my car seeing that you're making alot of generalizations about it.
1.I Am in fact running 40 PSI, not on a stock motor but a built bottom end. I've verified both readings with an in car gauge, then verified the accuracy with a mechanical gauge and an omni 4-Bar map sensor.
(Edit: I see that I didn't update the post when I built the motor again but it is built!)
2.The transmission is fine so far, and I am more than certain the car is making more than 225 Wheel.
3. Every car different and they react differently to different setups.
4.i can in fact spin the tires at 80 MPH
5.There aren't any videos of my car doing a full pull floating around the internet.
6. No one is purporting lies of any sort. These are just facts that I'm dropping coming from the person who knows the car better than anyone, which is me the owner.

That was a pretty aggressive comment. But understandable. When the numbers come out you'll feel alot better. Trust that I know what I'm doing.

 

[Tprate2]

I never really share any of my logs and such but here is one from January. I'm on and off the throttle with this log but i hit 40PSI around 4300 if I'm continually on it, unlike in this log. Really low timing and running the car rich. This was one of my initial logs when i first threw on the Holset. Just to make it to my target boost safely i took an abundance of caution with the timing.
Load dropping due to me letting off briefly.
Usually hits around 380 load around this point with the throttle fully pressed in.
I finished up the tune about a month ago so it's a lot more aggressive than this.
Built block, speed density, E-85.
4 bar map is calibrated to my current altitude in Evoscan correct formulas, and all so readings are very accurate

Well, you can't be wrong if you never get numbers on it, right?

I didn't know you had a built bottom end so I will cede you that. However, you wouldn't be the first person with "giant numbers" hiding behind a lack of traction or blowing through the trans. Things survive when you don't hook it up.

An h1c at 40 psi would be absolutely nuclear as far as IAT's and I'm sure your EGT's are as well running 10 degree ATDC. I dunno where your temperature probe is or what the latency is on it, but enough bigger intercoolers have struggled with better turbos at that boost level. A properly supported and tuned setup would be in a different universe.

You're welcome to believe whatever you want but when you put stuff out in the public's eye you better have your bases covered, and you don't. You came to me asking about how to set the car up for racing because you literally have a stock 3g with a big power plant in it. Go dyno it and go hook up first gear and see what happens. Just do us all a favor and post the carnage so a proper context is available to those who read about it later. That's all that matters to me.

 

[Silvertune]

Contrary to what you might think at this point I've been fan of your build for awhile. Learning and upgrading as you go is exactly what I did when I was starting out and nobody else on this platform is doing squat. My aggression is a knee jerk reaction after well over a decade of dealing with people who brag about how fast their cars are without any data to back it up and watching this platform rot because a few people in your position back in the beginning shared bad information.

If you keep pushing you'll eventually learn everything I've tried to tell you. These are mass produced cars, nobody is exempt from the limits. That's all there really is to say about it.

That's true,
It's all a work in progress, getting the car the way I want it. Making it hook is a work in progress. When things do break I'll go from there. I don't want it to seem like I'm not listening to any advice that I get but I really like to see things through for myself. Had I listened to forums back in the day claiming a 10 psi limit on the block I'd have never dared to do something like this, So I'm pretty much in the process of unlearning everything I've read before and trying things to see how they work out.

Yes at this boost level I'm sure the IAT, get really out of hand so a new intercooler setup is definitely in the works.

That's true, I did ask but I could have also just searched but who better to get some advice from than someone who's already done it on the same platform.
As far as publicity goes I stopped posting my 3G Awhile ago, I don't really care to publicize it. People can criticize the build but it really doesn't mean too much to me. I'm building the car for myself and not really to be seen, I can definitely upload a few videos if people are curious but first I need to sort a few things out with the car.

I didn't know you followed, thanks for the kind words!,, I get where your reaction comes from so I wasn't offended or anything but I understood where you were coming.

This is really a long term build so when I hit the limits I'll deal with them one way or the other. Working on the car has taught me a whole bunch. So I'll keep pushing and see what else there is to learn.

I'm gonna use a computer analogy that might be relevant to this discussion. Sometime around 1991, I bought my first computer. Over the following years, I started upgrading it by buying "better" and "faster" parts, replacing the original parts. Of course, I ran into some compatibility issues along the way, and consequently within five years, there was nothing left of the original computer, every single part had been upgraded. It was now a completely different computer.

My point being that yes, it is possible to turn a 3G into anything you want, but can you rightly claim it to still be a 3G in its final form???
