I'll start by saying that I hate threads like "I'm gonna twin turbo my car but I can't change my oil yet".

So, I checked through the last few pages of threads for a thread about this sort of thing, didnt find much.

Basically, I am looking to fabricate a third gen single turbo setup on the VE30DE.
The current turbine/compressor I'm looking at from a local friend looks about right for the application. Specs are:

T3/T04E .63 exhaust with stage 3 wheel
Compressor is a T04E .50/AR with a 57 trim wheel.

Thoughts, suggestions?
I generally try to keep my projects silent until they're done but this is one set of numbers thats hard to figure out without input from people who actually use turbos.

Not bad, but The comp side looks a bit small for you. Id go with about at least a .63ar on the compressor side. Then you be fine.

This sounds like a very common turbo found on ebay sold my mountain performance or something. Just saying I would stay away from these people. A 57 trim wheel is adequate, but I would go with a 60 trim instead.

As for what dixit said...They only make a .60 for a compressor housing. .63 is a turbine a/r only. But like dixit said, the .60 would be a lot better. But that place that sells those turbos doesnt sell turbos with .60 a/r.

As for a kit, PM if you want one already made for a good price.

I am with dixit. a .60 compressor would be better IMO

Im running a similar setup using a .60 compressor on a ve30de with no problems.

Do you have a dyno you could email me? bags533@aol.com

I am running a t3/t04e .63 ar turbine.. and I think a .70 on the compressor.

If not it's cool.. I am just curious about your turbo specs and the dyno curve. Thanks

I havent made it to the dyno yet, but when I do Ill let you know

So the concensus is that .50 is too small for this project. I'm not really sure what this means; whether it just wouldn't produce enough boost, or choke off the high end, or what.

I'm really only looking for about 8 psi.

subs1000w

it would proboly work for 8psi but if you go much above that it wont be efficient

the less efficent the compressor the hotter the air that its compressing becomes and that can lead to detonation which will end up blowing your motor

how good of deal is this friend giving you on this turbo becuase you could get a new T3/T4 with the right size compressor housing for around 600$ so if its not alot lot cheaper like as in 250$ i would just spend the extra and do it right. get it?

He wants $150 for it, plus a rebuild.

I figure at that price it's worth it to play with and mock up parts, get a little something working, then find the ideal compressor size.

that turbo would only be good for about 12 PSI on a 4cyl, so for a 3.0 littre you're going to be spooling quick, but it will be very inefficient at high throttle boost. smaller compressor a/r's means less airflow.

Turbo's for your engine should be the same size as a turbo from any other max, the important issue is the size of the engine, not how much power is made initially. Though initial power is important, when concidering your goals. (strength of engine) an old 3.0L will move air just like a new one.
