I cant find a strait yes or no asnwer. So heres my question. Can you hit 400rwhp with stock turbo cams?

That looks sick, do you need a special exhaust manifold to run the turbo on top or can I just flip the stocker upside down?

You'd need to cut the head flange off the manifold and weld it on upside down to do that.

Thats a top mount turbo manifold, what my buddy wants to do with his hx40 and 4g64

Ok thanks. I was looking at some HX35 and HX40 but they were saying they came on cummins motors? Is that correct? Wouldnt they be HUGE and have tons of lag off these little motors? Please explain

Diesel gases have less energy than gasoline gases. More heat greatly speeds spool. As well, a diesel redlines at what 3500rpms? It needs full boost at 1000rpms. A 5.9L cummins displaces the same volume at 1000rpms as a 2.0L 4g63 at 3000rpms. My bolton h1c, flows as much as a td06 7cm^2 20g on both ends, spools to 20ish psi in 3rd gear by about 3500-3600rpms. All the popular 4g63 turbo upgrades are used on large diesel motors except for the 16g.

There's a HUGE Holset database here, 8+ threads dealing with holsets and the sirius platform. Holset or other diesel turbos arn't larger than what we as a community already use. Their compressor housings are larger, which doesn't affect spool, and is deceiving. And their turbine housings are large, if you plan on using a non-divided runner manifold. Cummins diesels employ twinscrol/divided-runner tech. If you do want a true twinscroll setup, the hx35 turbine housing is actually probably a little too small to get the most out of the compressor.

H1C CUMMINS 88-93 WH1C 160HP 5.9 Turbo :eBay Motors (item 370219053832 end time Jun-29-09 09:36:17 PDT)
Is this the turbo you speak of?

 

[dsm-onster]

That's a knock off. Get a used h1c from an INTERCOOLED cummins pickup 1991-1993. It has a 54mm inducer (compressor minor diameter) or a Wh1c from a 1994 cummins pickup. It has a 56mm inducer. Or an hx35, 56mm inducer with revised aero tech in the turbine wheel.

Damn knock offs >< Ok so from what Ive gathered I would like to think these are some good turbos to choose from, please give me your opinion/advice

HX35-?
HX40-?
GT35R-?
Big EVOIII 16g-?
20g-?

Just buy some cams and stop making excuses, there not that expensive

You have a range of turbos from a comfortable 350whp with one to 700whp pushing another. What HP number do you want?
