I ran a Master Power GT45 (same specs as the Ebay unit) on a 6.0 LS. Made 600rw on 14lbs and was a beast on the street. Ran 10.70 in a 3400lb Nova with limited traction. Turned it up to 17 and did 10.45 at 132. I think you will be happy with it.

Some magazine put two on a 4.8L and made around 50 dyno pulls at 1000+ HP, never broke a sweat.

These little things are gems.

Ls1nova...did you run a single or twins?

LS1NOVA

single. Crap, two would have been ridiculous!

One is way too small for 383ci... two of them are a different story

Great turbo, I personally have not used one yet , but I have seen them used on buddys builds and they make good power and they have had no problems so far.

I think the exhaust housing AR is to big for 2 ebay gt45s but I may be wrong.

Look at the specs of the original post. Its a little small as a single for a 383 but not WAY too small. There is two different turbos being talked about in this thread. The one the OP is asking about has a smallish compressor wheel (68mm) but has a pretty hefty turbine (77mm) with a 1.05 AR. Better have a good 383 to run two of those.

I would work great as a 600-650rwhp setup as a single. Anymore than that and look elsewhere.

68mm turbo is way small for 383ci V8. That turbo may make great power up to 600-650rwhp, but would probably crap itself after that. Turbine side is fine IMO, but that compressor wheel is tiny.

OP - what are your goals for the car?

LS1NOVA

Ok I guess the OP edited his original post to say twin GT45's. Thats going to make a crap load of power. I guess the goals are pretty high. There was a silver Chevelle from MN making around 1400 hp on a BB with two.

ponjohn

I think two GT35's are a better choice...no?

My nephew has one gt35 on a worked Evo and it makes a ton of power.

Going to be running twin 70mm .82 AR on my 5.3...just depends on what you want to do and what kind of boost.

would two ebay gt45 turbos work well on a lq4 6.0??

TheLS1Lover

So basically your looking at twin T4 70mm Turbos with 87mm Turbines. It will work, but may take longer than you would like to spool. I say run em'! Denmah uses one from VS Racing and is at 20lbs boost.
