What do you think of this turbo for about 650 Horses to the rear through an OBX intercooler? Stock cubes about 9.5:1 compression.
Thanks for the assistance.

Check this out before you do that..... Joe is awesome!

I was going to run this turbo but I wouldn't be able to run the PR I needed to in order to be up in the map in a good spot to run that much rwhp.... if that makes sense. The turbo is good for 840flwhp as you see... but look at the map and then look at a consumption chart for a Ls1... though with lowered comp as you plan, it might work.

Hmm first off you need to lower you CF i will be running 8.8. YOu need to find a map and find what psi you want to run along with what RPM u want to spin to. Are u going to go with stock cubes or bigger.
The MP T70 is a great turbo will fit most low boost needs and some mid boost needs.
As for matching turbos and engine, use this link below...it will help.

BTW, we do match other turbo competitor prices.

Also, you might want to read this link as well about some of the MP T70 units that are floating around being sold on E-bay.

The 70's will flow about the same. Both are 70mm compressor and p-trim wheel. It will feed a 6.0L up to a certain level, but beyond that you will go past the choke line. The GT45 will do somewhat better, thanks to the larger frame compressor cover and large turbine side.

The attached image is the plot on a T70 turbo from my turbo calculator. Low boost setting is 8 psi and high boost setting is 14 psi. As you can see from the plots the turbo is too small. On the low boost setting you're dropping off the map at under 5K rpm.
I wouldn't go with it and select the turbo that is better sized for your car.

smokemup,
I think the plot would be much different then what is shown there, obviously your not going to be making those boost pressures at theose RPM's, so down low you will be in the efficiency range but up top you will be pushing the limits on that displacement engine and turbo. I originally had the T-70 for my project and went ahead and got the GT45 due to that fact, i am mor einterested in top end power at higher RPM then the quick burst of boost down low though, so depending on your goals, this is something to consider. again the GT45 will also drop some of the exhaust pressure due to its much larger turbine wheel and larger housing, keeping your pressure ratios in check much better and eliminating power drop off from choking. for the small difference in price, I'd go GT45 on your setup.

I don't have the map for the GT45 turbo so I can't say how it will perform. Based on the name I'm assuming it's a Garrett turbo, correct?

No, the GT45 is a Master Power unit. Bascially its a drag radial cheater 70mm turbo.

Cheater turbo bascially means small inducer with overly larger exducer and huge turbine. The GT45 uses a small 70mm inducer, but the exducer is almost 100mm. Your typical T70 use a 70mm inducer with 90mm exducer. The exhaust side on a standard T70 p-trim is 64mm/74mm exducer. The GT45 is a 78mm/90mm exducer, which is almost as large as a T88.
