Another 3.0 Turbo "How To"

[DustyR/T]

Ok, I think I'm ready to put my turbo set up together. I want a good turbo (that will work well w/ my engine) and I'm going to use a large front mount and have my buddy set up the IC plumbing. Is a T04E too big? Is a stock garret 89 chrysler 4cyl turbo too small? I want 5 psi and I'm going to upgrade the fuel pump, and injectors. Pump will be a Walbro 255 and the injectors will be mustang 30# injectors. I have my AFPR and it works great. Basically I am worried mostly about which turbo I want. I want decent mid range and peak at 4000 RPM on boost. I will be getting most of my stuff from E-bay (Turbo, Swing Valve?, injectors, IC, BOV, and some silicone hose couplings.) Should I get a 4 cyl chrysler turbo pre-set @ 7psi w/ internal wastegate? I'm really worried about where I'm getting my crossover pipe made for turbo.

Mods to Date
UD Pulley
Timing Advanced
52MM TB
2.5" Straight Side exit exhaust
Heavily ported head, shaved, 5 angle valve
Crower Cams
Plenum Spacer
AFPR

-to name the basics.

I think I'm bout peaked on NA power w/o going into the bottom end. So I really want another 100hp until I'm content. Please give info and pics please.

4 cyl chrysler turbo will get you 5 minutes before you over spin it and it melts. I believe Ondonti used a TE04H turbo on his car.

The crossover pipe for the V-6 is actually surprisingly simple to make.

The heck I did.

Thats like a mitsu turbo man.

I have an O trim t04 (t4) turbine with a 57 trim to4e compressor (which doesnt flow enough air for my setup).


I would go to4e (thats a T4) 50 trim compressor and a t3 .63 a/r stage III turbine for a comfy street turbo.

The 57 trim doesnt flow enough air on low boost levels, so you need a 50 trim.

Im looking for a MUCH bigger compressor myself.

oops, right. TE04H = our tiny mitsu right? You just had a big big T4

[Ondonti]

we dont have the ability to have our computers shutdown on overboost so I dont think a Mitsu would last more then 1 wot on a 3.0.

BTW go back on the 3.0 list. Hopefully that person will not post anymore.

ok, so a To4E will work well? I'm not using more than 5 Psi for now and it's definately getting IC'd. I'll be upping the injectors as I said before and putting in a better fuel pump. I don't feel like blowing the engine up. BTW, I don't even plan on "earing" it after it's installed. It's gonna get a Dawes device so I'm absolutely sure there are no "lean" conditions. Any other advice would be greatly appreciated. Can I use exjaust piping for the crossover pipe?

[DustyR/T]

I still need to buy a turbo mount bracket to be welded to the pipe as well right? My buddy works w/ piping and welders so I'm sure we could throw a rough design together before we say it's a go. And do I "need" to swap the plenum? Or is it possible to fit that lovely turbo beneath the TB? Probably depends on the Crossover design huh?

Look under the hood and see for yourself, Of course it's possible, it'd just be hard to do.

If you plan on placing the turbo where Ondonti has his, then you'll either have to flip the plenum or try to adapt another vehicles intake manifold to the motor. However, if you design the crossover pipe so that the turbo will sit forward or behind the area of the throttle body plmubing, then I don't see why it can't be done.

Just as an example, I'm placing one of my turbos just off of the front manifold by using a 30* elbow and a turbo flange. It will be positioned in a fashion that the down pipe will go in the area of the stock crossover pipe.

What your asking to have done can be done. But you'll have to be pretty inventive with your piping in order to achieve what you're asking.
