Re: Holset users unite!
Recently picked up a Holset h1c. Its in awesome condition. The exhaust housing is 16cm.Been through this whole thread and I have a few questions.
Im running a JDM GSR with GSR b17 cable trans rebuilt with synchros and mFactory lsd.
I dont mind a little lag if it helps with traction but im worried about spike. I just bought a PFab log.
My question is should i run the Holset 16cm^2 exhaust or look into a BEP .70 a/r. The car is usually used as a weekend warrior and occasional 1/4 track car. I am also considering all other variables such as piping length, innercooler size, etc..
Im still a newb when it comes to all this.
Any input is appreciated, Thanks.

16cm will be so laggy you won't even enjoy driving it... And either a housing that large you don't have to worry about a spike, you'll barely hit full boost

Re: Holset users unite!
My freshly tuned setup just for info
7 blade hx35 from a 24 valve with a Tim's turbo .63 hot side
Gsr
Manley h beams and Manley platinum 9:1 pistons
Precision 1000cc and auto phonics 300lph pump
cast manifold and Godspeed 38mm gate
3 inch full exhaust and skunk2 intake manifold
tuned on eCtune with boost by gear 👍
tuned by DKGoodrich on his mustang dyno in Frankfort KY
on gate pressure(5psi) it made 272whp
final pressure at 16.5 psi it made 354/254 and making over 250wtq from about 5000 all the way to redline.
fun on the street for sure

Re: Holset users unite!
that would be over 400 on a dynojet. your runing this on a log manifold? im looking to put this together soon but with a topmount or ramhorn. looking to make like 450hp probably end up getting a RLD Fab manifold since ive dealt with him before...

Re: Holset users unite!
yessir. with the assumed 13% higher reading of a dyno jet 24c it should be right at 400whp. 430ish on a dynapack setup

Re: Holset users unite!
so I was fooling around with the boost by gear in ectune earlier. I can't get it to make anymore than about 12psi in second gear. makes pressure fine in 3rd and 4th of course.
9:1 gsr hx35 with a .63 hotside cast manifold
any ideas?

Re: Holset users unite!
Be sure your waste gate activation is below your waste gate spring pressure. EBC activation should be around 1 psi.

Re: Holset users unite!
Ive been running holsets for years on my Ranger, but I didnt know you could get a turbine housing as small as guys are running. I have a few extra hx's sitting around, so maybe I will throw one on the civic. I would be interested to know where an hx35 or an H1c hits full boost on these little motors.

Re: Holset users unite!
i have found a hx40 parts
Compressor 62mm x 86mm 7 blade
Turbine Shaft/Wheel 76.00mm X 62.00mm 10 Blade
I am thinking of buying these and machining my hx35 housing to fit them. how would this setup work.
