sounds about right, whos turbo is that?

Looks like one of the Godspeed t88 or whatever they call it. Wheel sizes are decent but are probably old technology that doesn't flow what a comparable borg would.

You have an effin Z06, dont put a $300 turbo on it.

I assume your space limited? Front or rear mount?

370cidZ06

iTrader: (2)

Yes I own a z06 and didn't do it by waisting money hints on a budget, front mounted turbo no ac possibly no ps either

LS1NOVA

Well if you insist, the one you posted will get the job done without lag. Vettes are a bitch to do a front mount on but without ac and ps it should be doable with a decent sized downpipe. Smaller radiator would make life easier.

That turbo will choke on a 370 inch motor.

Pick someone that knows how to cam for the 96mm 1.32 borg warner S475...and re learn how to drive the car.... and itd be fine.

Worrying about lag and stickin a tiny turbo on a bigger inch motor is a mistake.

I was thinking the same thing, I just didnt have time to respond.

Borg is good, except fitting it in the front of a C5 would be a nightmare. There is a reason there isnt any decent single kits for them and the ones that do have poor plumbing. Your way farther ahead ditching the ac and ps but it wont be easy.

If it was mine Id go with a Precision 8847 since the turbine has a decently sized wheel and the compressor cover is small.

Thank you for a informative response was thinking of a on 76mm but the exhaust side is way to small a 74/64 or something like that I think. I also found a precision t7668 but that's a little small too and yes room is about 8-10ish inches the way I figured making the manifold work etc

LilJohn

Bullseye has a T4 based 1.30 a/r stainless Band turbine housing to fit the 96wheel.....

Itd work well in this application.

Any part number or price that you know of?

LS1NOVA

iTrader: (12)

Still have a huge compressor cover. How big is that Bullseye turbine? Even T4 I bet its pretty big pysically. It would be awesome to have a nice big unit on there though.

LilJohn

The stainless housing is a 400 dollar option. I had Bill build me a pair of these with the cast 80mm borg wheels for a 540 I specd out for a guy.. They were right at 1650-1700 each.

If you want one i could try and pull his string again.

Thanks I just found a 80mm Garrett air research with a 1.39ar t6 frame for relatively cheap. Do you think this would work 10" in length full frame ?

LilJohn

Gt4708?

Garrett has dimensional drawings of all thier models on the website... go snag those dimensions and see if itll work.
