gt35r or holset hx35

[MDCmotorsports]

Ive run the he351 Cw, just with different housings (hy35 housings).

The he351cw non VGT will not support the exhaust flow with the stock waste gate (internal).

You will see massive boost creep.

As for the V-band... just run a 4" vband. It should match up, or be a little bit off. That is what I ran, and it worked perfectly.

Oh, and be sure to add to your sig that you're in the "mafia" with the rest of us.

Rob21a48422, Has your car been tuned yet, or any updates?

MDCmotorsports, when you were running the HY35 did it have the late style turbine housing like the HE351CW, did you port the internal? What diameter is the port (internal gate) standard?

I've Built a few JZ and looking at one to put on my LPG powered Soarer

IIRC the hy and he exhaust housings only use a 3/4" wastegate port. Its very small indeed to try to handle the velocity of a gasoline engine.

Even porting it out to 1" or 1 1/8" would not do the trick.

Ive run both - the early hy housing and the late he housing.

You'll need to weld a plug into the wastegate hole, or weld the wastegate shut and run an external wastegate.

I do have the car running and I'm driving it daily. I'm running it off of the base map for a JDM 2JZ on my MAP-ECU2. It's running pretty good. I welded the wastegate shut and I'm using an external 50mm wastegate. Right now I'm only running off the spring. It only peaks at about 9.5psi and then settles in at 8.8psi so the wastegate is handling it pretty well. It's making full boost right around 3100rpm's. I'll try figuring out how to post the logs on here. I'll try getting one with RPM, PSI, and AFR so you can have a better look at how it's spooling. Give me a day or two to figure it out and I'll post it up here.

Off-Topic..........Jon, it's great to see you posting regularly again! I'm particularly enjoying this thread. There will come a day that i am ready to upgrade. The knowledge here will be very useful.

update?

o lot of great info in this thread....

i have a quick question... will i be alright with 720cc injectors running a holset hx55

 

[whitemike]

Price? Hands down the Holset Hy35, not the hx as the hy has a smaller exhaust housing.
Reliability? Hands down again the Holset. Ive seen the diesel guys cook these things to oblivion and the turbo still runs.

Spool? I think this may be a little bit of a toss up.

The hy flows about 57lbs a minute and measures the following

Compressor minor/major: 52.75mm/77.84mm
Turbine minor/major: 57.98mm/65.20mm

The GT3582R flows approx 61 lbs
Compressor minor/major: 61.4mm/82.0mm
Turbine specs: 68mm w/ 84 trim

So on the wheel ends of things, the hy35 is has a smaller rotating mass than the GT35R, but lacks the latest in ball bearing design. That being said, the hy35 and the he351cw have been called the "poor mans" gt35r.

You figure you can pick up a hy35 or he351cw used, running, for $300 or so. You will spend $1500 for a gt35R. Sure both could be blown up in a matter of seconds, but the holset will cost you $200-350 to have rebuilt. Or you could just go buy a new one. So in the long run, you could go through 4 holsets before you were up to the price of one Gt35R. Did I mention the Gt35R is non-rebuildable?

For some more thought provoking....

-Hy35, flows approx 57 lbs/min
-Hx35, flows approx 60.85 lbs/min
-He351cw (Spools faster than the hx35, but makes the same power) flows approx 60.85 lbs/min
-Hx40, flows approx 70.10 lbs/min
-Hx45 (can't find the flow at this time)
-Hx50/52 or 55. flows approx 99.20 lbs/min
-Hx60 (Notice I didn't say HT60), flows approx 125.66 lbs/min
-Hx82, flows approx 198.42 lbs/min

AWESOME info here MDC!
