Where I would clamp the coupling down, the diameter of the housing is small and I'm worried about leaks...

 

I clamped it on the housing, as close to flange as i could. i have boost leak tested my setup to 30+ psi no leaks

 

With a 2.5 coupling?

 

Finally cracked the obx manifold. i guess after 16 psi antilag and 2 years of driving it went. going to tig it up and keep going.

 

My 6765 took a **** on my S2000. So I put HE341 on it. It made 522whp@25-26psi.

Tuff as nails!

 

Up for those who are interested... turbo is off 06 cummins 5.9. Car made 305/200 at 10.8psi boost pressure, Evans tuned.... pretty conservative tune, probably a lot more in the car, just didnt want to push it with the way I drive the car. Dyno Video posted. Hope this gives some insight to those who want to try this turbo... Its a bit big for the b16a.... 5200 rpms before boost starts coming on, but overall very happy with the turn out.

Setup:
Bone stock b16a bottom end, ARP head studs,
stock B16a head with GSR cams, CTR valve springs
ID1000's
Full-race ramhorn
Full-race tial 44 MVR gate
Custom piping, fabbing, Backmotorsports built (nasteboyii on here)
Greddy BOV (dont think its working well as you can hear surge I think in video)
3" Exhaust with CAT onto a Cutout
S300 with boost by gear option
GSR trans, ITR limited slip

'in the makes':fully built ls/vtec with a fully worked b16 head from endyn w/ a hx40!!!!

 

Do I need to use a restrictor with a hx35 on an ls/vtec? -4 feed line and a -10 drain.

 

thats my oiling setup on a HE351cw turbo (which is pretty similar).... as per Holset, the turbo can not see more than 75psi oil pressure for any length of time, so as long as ur under that you should be fine.

 

I have used pretty much every holeset combo never any restrictors. -4an line

never any problems

 

Pretty n00b to these turbo's and turbo car's in general lol. But do you HAVE to run a twin scroll type manifold for these turbo's?

 

absolutely not, however running a twin scroll manifold will cut down on spool up time by 500rpms or so.... but its not necessary

 

Thanks alot man just was sorta confused by the divided hot side housing.

 

dont have a dyno sheet but the old f22a made 365 hp 300 tq 16psi with hx35/hx40

 

anybody running a 9cm housing on a h1c? Putting this on a stock b18b1 only wanting to run 12 psi and make 250+ whp for now will ill be able to do it.

 

I run a 9cm housing on my setup... see above in this page. Its a 60mm compressor, 60mmturbine (he351cw). your spoolup should be about the same as me, maybe slightly faster.

 

man im really thinking about getting rid of my h1c. Im just running a stock b18b1 and im going to have to shift at like 7k. So hitting boost at 5200 is kinda wack to me somebody change my mind.

 

Where can one of these 9cm housings be found at?

 

Figured I'd check in here and report.

Hx35 8-blade/ 12cm^2 on a Ramhorn
81mm B16 stock sleeves with forged internals
B16 Head/stock ports with: ITR (01' cams, IM, TB, Valvesprings).
2.5" Charge pipes through PWR FMIC,
RC1000's stock rail and FPR.
3" exhaust/ 38mm WG.
eCtune and Boost by gear fun.

475whp/ 298tq on 92 chevron pumpgas @25psi. Rev limit 9,500.

The H1c is actually smaller than the He351cw now that I think of it, so you should see boost no later than 4.5-5k i would imaigne.

 

There is really no reason why you shouldent have a holeset on your car unless you want 500+whp

 

and even at that power level there are holsets out there that can make that power and beyond.... From what I have read, holset wheel design is quite advanced and rivals that of the garrett GT series.

 

thank you guys guess i will i be keeping the h1c. ill try to find the website where i found the 9 cm housing.

 

I found some housings here http://www.htturbo.com/thnew.htm
oh yeah what size oil line fittings are you guys running on h1cs?

 

The drain is a standard t3 fitting, and the feed is a 12mm by 1.5 pitch, then just add your -3an feed or -4an, whatever you want.... I think Im using a 4AN
