Free new turbonetics turbo--Need some insight.

[streeteg]

A buddy of mine gave me this turbo

http://shop.vendio.com/crowder...01362

T3/ .48 AR 50 trim

trying to convince me that it should go on before my tuning date, but its smaller then the stocker thats already onm there which I have zero problems with.

So i guess the question is- smaller turbo w/ 20-22lbs of boost or stocker with 12 lbs

Anyway any help would be appreciated.

What make you think it smaller than the stock turbo??????????????? Stock is a hybrid T-3/T-28...with ceramic wheel and liminted boost...

I was under the impression that the stock turbo had a .63AR? Or does that first comp wheel 48x66 mean .48ar

That exhaust A/R looks teeny tiny to me. You need a compressor map to see if you will outflow that turbo or end up to the left of the surge line.

I dont have a stock compressor map but here is the one from Turbonetics. Not like i really am educated quite yet on how to read them-- so maybe someone can lend a helping hand?

its the 50 trim .48 ar. Like it says on the description for small displacement motors etc etc.... I get its not the ideal turbo upgrade---I am just wondering if its worth it to throw on the RB or not, run an external gate and have for the most part a pretty linear turbo powerband. Power goals for my car are 350(usable)whp.

Thanks guys

The T3 Performance Series Turbocharger is ideal for small displacement engines with horsepower returns ranging from 150HP to 325HP.... directly from the site you linked. These are flywheel numbers as well.

Too small, not worth the hassle IMO.

to small for the rb. look at the map at 15psi and 250hp or more you will be off the islands and pumping heat

It depends, are they rubber ducks or real ducks?I'd go for the rubber ones.

That turbo is way too small for an RB...I say sell both and buy a holset.
