My 20v turbo Corolla wagon project
 

Whats up guys. This is Jeremy aka berminator's friend Gavin who was at the install a while back. I had a 20v 4AGE powered AE92 Corolla wagon down there and I can remember a few of you guys calling me a ----- and all this for not wanting to turbo it. Well, a while back a foreign object found its way into my #4 combustion chamber and destroyed the piston and the three intake valves. So, the obvious course of action was to throw in a set of the forged, oil cooled and ceremic coated 8.9:1 pistons from the late-model 4AGZE. Becuase the 20v silvertop shares the rest of the internals with the 4agze, my motor will be able to handle 350+ hp all day long with this setup.

For those who don't know, the 20v 4AGE is a 1.6L twin cam with five valves per cylinder and ITBs from the factory. This is the later version of the American 4age which was discontinued after the AE92 GT-S. In Japan, the motor was found in the Corolla Levin and Trueno, which were kinda like Toyota's Integra. I have the earlier version of the motor, which was made arround 93-95 and had the 4agze internals, minus the pistons. The later 20v had much much weaker internals but larger ports.
Anyhow, sorry for the history lesson...

Here is what I am thinking of using / have for my setup so far:

4agze 8.9:1 pistons* (Soon to be flycut for the 5th valve, to keep the motor non-interference)

TRD .8 mm head gasket*

Starion, SRT4 or other FMIC that will fit (Short on space)
2 1/4" charge piping
Custom 3" downpipe and 2.5" for the rest
Stock intake manifold for now

This is what the motor looks like together. The only pic I could find was during the install, which sucked bigtime as you can see.

My dash setup. Thats an AE92 GT-S tach, mounted where my speedo was. That blue thing is an Apex-i RSM, which tells me speed, RPM, 0-60, stuff like that. I am going to try mounting some gauges where the tach was originally.

I will be using an aftermarket Civic radiator because my turbo doesnt quite clear the stock one.

Just baught a wideband O2 sensor, and Apex-i oil and boost gauges for the dash.

There is a guy, Yasin aka slownrusty on Club4ag who made an AE86 coupe with a very similar setup, only 8.0:1 pistons. At 4.5 PSI he made 204 RWHP. He is currently running 7 psi and putting down 218 whp. So yeah.. my car should whip.

I'll keep this thread updated. Let me know what you guys think!

That turbo will be too small. That motor pulls way too high. Doesn't that redline in the 9's?

Re: My 20v turbo Corolla wagon project
 

I have heard that criticism before, and I know on a B16 this is a concern, right?

People actually recommend using t25s for my motor, depending on the application. They have bean known to work with no problems. I dono what to say.. It makes sense to me that it would be too small but its been shown otherwise.

Oh and my motor redlines at 7800, but yeah it doesnt take much at all to change that. Certianly nothing to do with the rods or crank.

Re: My 20v turbo Corolla wagon project
 

Not that is wont work, but there may be better choices for larger hp gains up top. At 8k it may just blow hot air.

Re: My 20v turbo Corolla wagon project
 

I should be able to break 300 fwhp by about 15 psi, thats enough for me personally. Maybe it will blow hot air, we'll see.
If I boosted it to the 20-or-so psi my motor could handle than yeah I'd buy that.

Thanks for the input and I hope to see you again on the 10th.
Oh, and do you know anything about Megasquirt? I will be needing a good tuner soon.

Re: My 20v turbo Corolla wagon project
 

Cant say that I do, sorry. I dont know anyone in the area that uses megasquirt.

Re: My 20v turbo Corolla wagon project
 

Hmm. Is a tuning platform a tuning platform, to any extent? Maybe getting a wideband and learning how to street tune myself is the way to go..

Re: My 20v turbo Corolla wagon project
 

You could always get bigger injectors and S-AFC hack. Maybe use an MSD BTM for boost retard. My Toyota knowledge is extremely limited so I couldnt tell you what injectors swap in. This is kinda crude but it's been shown to work in pretty much any setup.

Re: My 20v turbo Corolla wagon project
 

300whp with a .42/.48 is pushin it. go with something bigger.

Re: My 20v turbo Corolla wagon project
 

I'm chill for now. Im gona hang out arround the 250WHP mark for a while.

Fulcrum- I have the AW11 3SGTE 430's, I shouldnt have to replace them for a while.
I allready have my mind made up on MSn'S.
