there are a couple of cool calculators on that site. i think the turbo size calculator is pretty accurate. it tends to lean towards ball bearing turbos though...which are quite a bit more expensive.

Re:turbo size
 

fill me on in what you plan to do in terms of HP and boost. along with the current VE of the engine the way it is

Re:turbo size
 

im shooting for low 12s/high 11s. ill build it until i get there.in stock form it is a 2.5 v6 with a 164bhp rating.i also plan to do these numbers with mostly oem parts.

Re:turbo size
 

honestly, i would say go with a t3/t4 (fluid bearing) turbo with a 60/63 a/r and a stage 3 wheel.

that will be plenty for what you need.

Re:turbo size
 

yes but these things are monsters when turboed.how does 400 whp on stock internals sound?thats the only reason im looking at bigger turbos than a hybrid.

Re:turbo size
 

are you saying that those stock internals can handle 400 hp???????? wow.

BTW a t3/t4 of the spec i gave you is good to roughly 550 hp. although (again) i dont know how much power you plan on putting out.

Re:turbo size
 

the actuall HP vs Airflow thing depends on the mechanical effiecnecy of the engine. id be willing to bet that a holset hx35 or hx45 might be a better cheaper choice and is more then capable of deliring the goods. they are the standard turbos on the newer dodge turbo cummins diesels.

Re:turbo size
 

ill make sure and look into that turbo.and yes with a little tuning and bigger injectors these things will take 400 hp all day long.and by oem parts i didnt exactly mean oem probe parts.youd be amazed at what kind of piston/rod setups from other cars fit in this thing.

I got a .60/.63 T3 60 trim used. i was going to put it up on ebay Monday but Id rather sell it here. Make me an offer if you want
