Sorry this probably doesn't answer your question but good info

That turbo can flow about 600 CFM of air I believe. It will depend on what type of fuel you are using, but on pump gas I would say go for somewhere in the neighborhood of a 750 - 850cc injector.

I'd suggest 850s or 880s

Can you be any LESS specific?

What compressor wheel spec? What turbine wheel spec? What turbine housing spec (flange type and a/r)?

 

[morelock]

.57 compressor wheel trim
.50 a/r compressor
.63 a/r turbine

/\ No kidding!

Start with uploading some pics if there are no other numbers on the turbo.

A 57-trim is rated at a shade above 50 lb/min peak, so you'll probably be seeing airflow around 46-47lb/min at 20-22psi depending on your supporting mods.

A set of 750's would work, but 850's would allow room to grow assuming you'll want to one day run more boost. This depends on what fuel you'll be using as well as what you'll be tuning with- you can't tune anything larger than 650's with an AFC, for example.

Sounds like Ebay already.

 

[JusMX141]

I agree.

...which means at the 22psi the O.P. is planning on running, pieces of the turbine wheel will be exiting through the exhaust.

sorry no picks the car in Norfolk i got few to Chicago or school for the navy. and no!! it is a garrett the only thing ebay on the whole car is the wast gate and manifold that has been ported to hell and back that came off of my buddy's 2g.

and i will be running 93 in it with a walbro 255 and ecm link as soon as i get taxes.

I run mine with 680s at 23-24 psi but my idc s are pretty high too so go with 750cc our bigger unless your using dsm link to tune then go big and you will only have to buy injectors once.

 

[morelock]

ok thanks ill will probably get 850 or 950 for it then thank you.
