Calling all Holset people. I wanna join the Holset club

[mk2 supra]

Okay so in the words of ricky bobby, I wanna go fast! First of all lets keep this stricly powerplant talk. So far Ive been a BPU 7MGTE, thats ran mid 13s, granted its been a lot of fun but time to go faster. The engine is very fresh and sound and I wanna take advantage of the Holset turbos that are working for so many and push things a bit harder, was thinking an HX35. Im wanting around 450whp, with a decent spool still, I will be using water/meth injection on 92oct pump, and hopefully still piggybacking with a GM MAFT. So Im gonna go over what I have planned, and if anyone has "been there done that" and has a better way please let me know. I dont wanna go the route of a bolt on CT, the price seems a bit up there, and a 57 trim at this level would be overworked and wouldnt like life much.
Im doing either a T3 or T4 flange, I know these holset housings are huge, Im mainly concerned on what will clear the block/strut tower

Thinking this exhaust mani

I like cast since they dont crack, but again, clearance
So this would be 2nd choice

Then some kind of EWG, pretty standard there, been running a walboro 255 thats rewired to 10 ga so should be sufficient already, injectors Im thinking something around 650s, since too big on a piggyback screws with timing, and I think 550s would be too small for my hp goal. Thanks in advance for any help

My clutch got here today, just waiting to order whichever exhaust I should get. Anyone have experience with one of these Im looking at?

i have had a hx35 on my 7m but it was low boost like 11 or so and hit fuel cut right off the bat. What holset do you have? I have a hx 40 that i was going to put on but I posted it for sale and no one wanted it. On my 35 set up I welded the waste gate flapper and went external gate sounded so sweet. I sold it to a friend who put it on his 2j at 16 psi probably the scariest car I have been in shit is no joke. Summit racing have down pipes made just for the holsets check it out under 100 bucks last time I checked.

I'd run hx40 and t4 manifold.

Sick man thank you. I actually dont have the turbo yet, is yours still for sale? PM me. Im very open to HX40s as well

Where's the link? You know we don't want to do our own research. :nono:

I got this information below from http://www.supramania.com/forums/showthread.php?101938-gt35r-or-holset-hx35
-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

A turbo moving 60lbs/min is said to support 600hp at the flywheel. He notes that the HY35 moves 57 lbs/min and assuming it spools faster than the HX35 because of smaller turbine housing.

Something that is not on that list is the sub model of the hx. I know the 35 comes with a 8 blade and a 7 blade with the 7 blade flowing more, I believe the 60 lbs/min. The hx40 comes with a 7 blade and a 6 blade or the super 40, I'm unsure of the super 40s flow but I believe the 7 blade hx40 and 7 blade hx35 have almost the same flow IIRC.

Found it. Ill pass on it, since it might not even fit into the tight mk2 engine bay, and Ive built all my exhaust so far anyways

The turbo fitment of the cast one looks effed... So Im probably going with this one... does anyone have any experience with this mani?

Well, it's an exact copy of the china manifold that driftmotion sells. I use the same manifold but ceramic black coated, inside and out and minor porting/cleaning slag.
