Turbo Sizing

[NickAlero2000]

Hey Guys,
my power range is changing to fit my budget at college, which since I'm not at HVCC anymore (sry Billy :( ) , I'm paying way more for school and kinda want to save a bit. I still want to turbo, but I'm looking for the safest HP numbers I can get without building the engine (when the time comes, I will build...but its not the time yet).
Turbo sizes? thanks all!

while people are answering.... what would be the downside to using one bigger then you need? wouldn't it just be pushing less air then its capable of?

[Gr1m]

no it would just take too long for the turbo to spool

GT30/35 would be fine. Just control the boost to where you want it.

C2;445919']GT30/35 would be fine. Just control the boost to where you want it.

On a stock bottom end, keep things under 275hp'ish.

A GT30R at less than 10lbs will keep you there. a GT35R would be already too big.

It just so happens I still have it.

I was going to say GT3071R. It'll spool a little faster than the GT3076 and it's more efficient (puts out cooler air) at lower boost levels. But if you can get a deal on Spy's 3076R, then by all means, that would be the way to go, especially if you do actually plan to build the engine in the future :thumb:

According to the garrett's site, its internally wastegated. Confirm/deny?
can an external and internal wastegate be used?

[spyhunter]

My turbo is wastegate'less.

I know this :D
I have a good memory haha

[Spilner521]

If you have a manifold without a wastegate flange, you'll just have to have a wastegate flange welded onto it to run external. It's really not a big deal.

Send it to me, I'll weld it on for ya :thumb:

I just so happen to have an exhaust manifold w/ a wastegate flange too.
