thanks alot justin, i'll have to give um a call and figure out what size A/R it is. it would be a amasing single/top turbo

If you look at the attached Garret specs, that turbo is ideally sized for around 475 hp. The compressor side and the turbine side are too small. It is sized for up to a 6.0L motor. Even at the largest A/R of 1.19, it doesn't support enough exhaust flow for big HP. It would likely work with a huge external waste gate so that enough exhaust could be bypassed, but it would make for a system that would have high exhaust temps and it would be hard to make it work well. It would be a good as a twin setup, if you could get another one, although it would probably be a little laggy as a twin.

A better choice for a single would be a 4294R (94 mm) or a 4202R (102 mm).

yea, the more i look around and research the less appealing. what do you think about a 64/71/13(maybe a SS cover) then putting a S488 on top of it down the line? i have the fuel now to run the 64, a better cp3 would fuel a 66 no probs, im open to idea's, and they dont have to be a BB turbo

I just noticed you are running a diesel. It would be a decent fit for you.

I'd do the SS so that you can run higher EGT's. I would think the 66 would be so laggy it wouldn't be fun as a dailer driver, but would be great for towing.

Do you have the intake and exhaust for a 64? If you supplemented with a 50 shot of Nitrous or a propane kit, I think a 64 would be a blast. I'm not really a diesel guy though, so others may chime in with more experience.

I have two new 88mm Garret turbos in the garage for sale that will do the trick!

WOT: ive seen that truck over there, its a nice rig. bare in mind he's prob running down the track at 4-5k rpm's. i have the fuel and tuning to run the 64 with no probs, and right now that would put me in the 600 range right off the bat.

turbo's for diesel and gas are very similiar in concept

RHINO: specs and how much? might be a good bottom turbo

 

[WOT]

Notice, he is running the 62/71/13. I would think the 64 and larger would be laggy.

Not sure about the actual specs. A friend and I was going to build a twin turbo 03 mustang with a 400 cubic inch motor. We got most it done and then we quit on it. He sold the car and has the turbos in my garage he wants 3000 for both of them.
