And look at the 'cheap' S400/75 that's worked so well on everything from a stock 350 to a mild BBC: compressor 75x100, turbine 96x87. I think it's the same theory at work there too; it's past time for the small turbine stuff to crawl off into a hole and die.

 

here is a link to a 76 and a 80mm with the 77/88mm turbine through cx racing a little more and you could go with Borg Warner

I'm a dealer and can save you guys a little if ya wanna try one

 

Yeah, but, the turbine needs to be bigger by about the same amount too. At the power you can get out of a 76 or 80, and on a decent size engine (6.0L LS or 383SBC, say), the 88/77 turbine is a bit small. On less engine it would make more power. And the Magnum stuff is getting pretty close to the same money as the S400. It's less of an issue than I'm making it out to be though, at that power level everything else is more money too, which makes saving $300 on a turbo much less of a big deal.

 

OK which one of these turbos would work best as a twin setup there all GT35 turbos but all 3 have different wheel sizes

Ever get it running?

 

Its fully assembled and sitting on a stand but thats as far as i got. Im 99% sure its going into my daily driver 71 chevelle with a budget china twin turbo setup with flipped patriot shorty headers. I have the entire used turbo kit and most of the parts but havent found the time. It would be a vacation for that engine to maybe make 800 hp with the play toy turbo kit slapped on it!

 

"with flipped patriot shorty headers"
are these the headers?
https://www.summitracing.com/parts/pte-h8036/overview/

do you run them upside down, or mounted left to right and vice versa?

 

Nope thats not them. Look up Patriot brand ultra shorty headers that are center dump and flip em up, cut the collector off and add pipe to your T3 flange.

 

I just realized i never posted the fact that the grenade has been installed in a somewhat junky 71 chevelle for quite a while now. Single 4 barrel and no boost for now. I wasn't driving it because immediately after startup something had happened to one of the cylinder heads and it lost compression in one hole.

I finally tore the head off to fix it and found out the recycled heads from my old blower motor had been abused so bad that one guide had shrunk to the valve stem and the guide fell out of the head and slid down the valve. LOL. It bent the valve and ended up getting all the guides in that one head replaced. I was too lazy to do the other side and simply slapped it back together.

So far so good as it has a few hundred miles on it making boring N/A power. It does pretty good if you wind it up real tight and some gears and stall converter are next on the list. Call it "retirement" for the old girl at least for now. I think it earned a somewhat normal life!

 

sometimes boring NA power is better than nothing at all.... glad to see the grenade out and about
