IMO I wouldn't cheap out on the turbo if anything. I've heard nothing but good things about the MPT70 and that's what I'm going to be running.

I considered that same turbo, but now I have a MPT 70 sitting in my bedroom, while I gather all of the other parts i need.

I've actually heard good things about these eBay units. Two of these on a big block = 1000 rwhp. One drawback is that they are physically huge and weigh close to 40 lbs.

We have used plenty of the gt45 ebay ones, An never had a problem with them, I think we have used about 5 so far on different setups, Have seen 18pounds on a couple with no problems, Just prime them right.

interesting. any more input?

i could get 2 gt45's and run twin turbos. that would end up the price of one MPT70. but its no lag and plus if one was to go down, i still have the other running

Check out Aprils issue of hot rod magazine. They did a 5.3 with one of these turbos. 594hp. So they work just not sure for how Long they will work.

if you are doing a rear mount do not use the ebay gt45 turbos, We use them a lot on different ls builds, We did one on a rear mount an couldnt build boost for ****, just a heads up i have pics aswell

Have you any exp running twin turbos from this seller. I see gt28, but I guess they are to small for stock ls3, any suggestions? Thanks

what size are the GT45s? Im not looking for any crazy amount of boost but a good 5-7psi would be nice to make about 450-500ish HP. Trying to make more of a autobahn hauler, not a 1/4 mile drag queen. but a nice 12 sec run would be nice too

Ive actually went with a T70 ebay turbo with a .84 AR Turbine housing. Just getting a somthing to start with. oil system will be remote as well to keep running lines to a minimum.

Hey grooms, I made about 2 #s in about a half mile run on 231, It sucked so i swapped out to a gt42 i believe was the size, The size of the gt45 ones we use, has a 4 inch inlet, 3 1/2 exhaust vband, t4 exhaust flange, 3 1/4 outlet, i think .96 exhaust cant remember the intake side off hand right this minute
