Holset Turbos

[sleepydsm]

If the HX 35 has done over 400whp, I'd probably go with that. And I'm sure if I didn't get that power with that turbo, something else is the problem, not the turbo. Setup I was thinking about:

HX35/40 with the .55 A/R BEP housing
FP Race manifold
Ebay external dump o2 modified for tial 38MM
Ceramic coat hot parts
1600cc's
e85
DSMLinkV3
BC 272s

Sounds like a good plan.

I know a guy that has had HX-35 with the BEP housing on his VR-4. He has HKS 280 cams and that thing spools like crazy. At part throttle at 10-15mph you can hear how that thing is begging to be pushed, spooling for no reason just waiting for you to hit it. It hits like a 16G.

Is it this guy (http://www.galantvr4.org/ubbthreads/showflat.php?Number=406669&page=&view=&sb=5&o=&fpart=all&vc=1)?

I dont have any personal experience yet, but after a month of research, I ordered a 7blade HX-40 with the billet 69lbs/min wheel. Ill be running it in a SS BEP Bolt-on housing.

There are pleanty of real world numbers that justify the claims made about these turbos. And although I am just learning to read compressor maps, they do back up the claims of these individuals.

SleepyDSM: Acccording to what I have read, a HX35 in bolton form will support 450 on pump, so on e85 I dont think you have too many worries. And in a BEP housing, spool claims are around 3700 for 20psi

^I plan on running the latter.

The V-Trim is absolutely amazing, but I agree, the HX-35 is pretty well suited for the 2.0-2.5L engine range.

I have a buddy who has a Merker XR4Ti 2.3l with a volvo DOHC head and a HX-35....the thing screams!!

That's what Colin is running now? Haven't heard anything from him in a while now. His car rocks.

Holset's and BW's both are very intriguing to me. I may have to run one or the other.

eh i said f** it and a bolt on HX40 is in the mail.

Which hx40 compressor wheel? You should easily reach your goal with that turbo (regardless of which hx40 compressor) and your above list. Keep us posted.

I prefer the bolton hx40 over the hx35/40 any day of the week. Considering the spool speed, go a head and get a turbine that better matchs the compressor. It's good to see you stick with the turbine wheel that better matches the compressor wheel. You can get more out of a smaller bolton housing when you better match your wheels. If you were set on not going over 450 whp, I would say stick with the bolton hx35. I don't see a good place between the *bolton* hx35 and *bolton* hx40 for the hx35/40 hybrid. It probably could eak out over 500whp, but you'll need some healthy boost. The hx35 turbine wheel needs a nice size open turbine housing to get the most out of it and get into the potential of an hx40 compressor.

That would be one badass street setup! You're gonna have to give me a ride when it's done!
