Turbokit for 3SGE engine?? Options

[Robban]

Is there a turbokit for the 3SGE engine?? i´ve searched alot but havent found anything or is there any other way to get more hp under the hood? now i only have an open air filter and 2,5" exhaust. but i want more.. any tip anyone??
i could probably have someone making turbokit for my car but i think it would be to expensive.

i'm pretty sure some one makes a turbo kit for the 3sge.. just keep looking

HKS makes one using their 3037S turbocharger.


try looking at

Let me say that you have a very nice engine.

Spend some time on todaracing.com, junauto.co.jp and other sites.

My advice to you is to take it in steps.

If you need more, I will reply to your post.

Just be serious about it and in the mean time, do some reading from TurboMagazine, RedLine Magazine, Super Street Magazine and Modified Magazine.

You will learn a lot.

The exhaust manifold bolt pattern on the 3SGE is the same as the 3SGTE, so any turbo kit for the 3SGTE (which will be the 3rd gen in your case) will be a direct bolt on for your car. The only extra steps you need to do is tap into an oil line, which is as simple as putting a T connector between the oil pressure sensor and the head. The other step is an oil return port, which just needs to be drilled out.

As I've said on another post, I am in the process of converting the same motor to 3SGTE. Its sooo easy it's scary. I'm going a bit more in-depth with my buildup though, and switching to stock ST185 pistons. But everything outside the block will be the same as yours.

So, here are a few choice's for you:

A stock 3SGTE manifold (can be purchased from your local Toyota dealer for around $150 USD), and CT based turbo and custom DP ($250 used). Figure $100 for fittings and lines. You would also need to route water to it, which is really easy.

A stock manifold, CT to T3 adapter ($75), and any T3 based turbo (w/internal wg) and custom DP ($500- $1600 new). Since your compression is so high to begin with, anything above a standard T3 would be a waste of power. For instance, you could bolt up a Greddy 20G kit, which doesn't use water cooling - less lines to run, but its high boost output would create the equivalence of 18:1 compression - good bye motor.

Paul Rennison's exhaust manifold 325 Euro, T3 based turbo w/ internal WG and custom DP.

Then, you'll need an Intercooler, which is really easy to do with the side mount TB. There are a ton of options - my buddy just made an IC using 2 Saab 900 intercoolers welded together. Cheap and very efficient.

Isn't the 3sge a high compression engine? If it is, then you would have to do more work than just bolting on a turbo kit. Turbo's dont like high compression.

It is not the turbo, but the high compression on the head + turboing pressure.

You can leave it the same and use up to 8psi or even up to 11psi, but to be safe, up to 8psi is good.

If not, get some toda racing or jun 3sgte piston with a rebore to 2.2l and you will be good to go.

Thanx for all answers. it helped alot but i think i have som more reading and learning to do before i start this. im a terrible mechanic. thats why i wanted a whole kit, tested and ready to bolt on. but doin it the way scothaniel described seems to be the best an cheapest way.. i just have to save up some money and get all the parts.

about the compression problem... ive read about other turbo kits were they just used a thicker headgasket (is that the right word ) to lower the compression. is that maybe an option in this case?

[west_minist]

Yet, thicker head gasket will do it, or just buy jun stroker kit if you can w/ rebore.

You will be very well ready!

My advice to you again is to just get a apexi safc and a ignition box like MSD Digital 6 or 7 plus and MSD HVC II coil.

I am getting a 7 for my subaru until I get my corolla w/ 4age 20v black top.

Add to that, a adjustable fuel pressure regulator w/ boost control.

But try to get the car to handle well and enjoy the car.

Actually, turbo's love high compression pistons - you just need a TON of gas to keep it safe. I remember reading an artice in Max Power (UK edition, not the pathetic US version) about Norris Designs 700+ Evo running 11:1 pistons with a huge HKS turbo. They were running out of fuel with 1000cc injectors at 2.5bar, so they added a second set of injectors!

For the rest of us, low compression pistons are a great safety net. I'm going cheap on my motor, since its for my wife's car and she doesn't need 350+ hp. I'm using a set of used stock all-trac pistons with new rings and all new bearings. All total it was like $300 for parts and labor. I'm also using a TTE head gasket which is good for 20+ psi of boost.

I personally dont like using a thicker head gasket as a way to lower compression. It usually only gives you around 1 less cr (which would put you at 9.5:1) and puts more stress on the gasket, which is a known weak point on the 3SGTE. Then again, if your not pushing 20+ psi, and you use a HKS 1.6mm, you wont have a problem.

[west_minist]

You normally run low compress to run high boost which mean more oxygen.

More oxygen means more power.

If you need power and do not want to run alot of boost and serious tuning, higher compression comes into play.

Right now, a 4age 20v with 8.5:1 pistons is dead. Very dead. You have to run atleast 8psi to feel almost the same. But the aim is 18psi. Cannot run that on a normal 11 head. It must be build to handle the heat, which will cause pinging, piston melt down and other things on a normal head.

I have seen what 10-12psi does to forge pistons on 11:1 compression with lack of bas and good cooling.

This is sweet

Ive found a used turbo from a celica ST185 cs. is that something that can be used? the guy wants about 400$ for it.

[Robban]

Maybe its a bit overpriced for a used turbo?

So let me see if ive got this right.. its possible to install the turbo without getting new pistons or thicker head gasket and it will be safe for up to 8 psi? about how much more hp would i get doing that?

Im having a hard time to understand everything. the schools in sweden doesnt teach you this type of english just casual english is pretty easy but this terminology is really hard. but im learning

thanx for taking youre time explaining for me. i appreciate it very much.
