ok so my very tired and beat master power t3/t4 with stage 3 exhaust wheel is about toasted,might have even sucked a rock into a little while back. so I have been looking for a holset. found one today h1c guy wanted 150 got it for 80 and orderd a rebuild for it just for peace of mind. just wondering if anybody has used these much? or how bad this thing is gonnna lag on my gsr. so what do you guys think?

Noone has ever used that turbo. Your on your own in these uncharted waters

shanerv · « **Reply #2 on:** August 06, 2010, 09:15:48 PM »

i have seen a few guys here used them but nobody has used one on gsr yet. and I was just curious about how it would spool

SloS13 · « **Reply #3 on:** August 06, 2010, 09:31:07 PM »

it'll spool a little gradually at first, then at a certain point it will begin to spool much faster.

it will spool even faster if you don't use a gate.

h1c comes in numerous sizes so yes it will work.

Dude, you know a Holset turbo is made for diesels, right? It won't work right on a gas engine, they're completely different. Diesel exhaust is so much different than gasoline, and your gas motor won't spool it for shit. And if it does, it will DESTROY the turbo. It won't last 500 miles. You're better off selling it to some ricer and buying a Precision, or Garrett GT. You also know that those shitty Holsets are journal bearing, not BALL bearing. Ask any racer, any REAL racer. Ball bearing is the way to go, for power and durability.

You'll blow the welds on your intake manifold, then tear the block apart to replace the piston rings you'll have fried.

buy new floor board screws NOW

keelay · « **Reply #9 on:** August 07, 2010, 12:13:19 PM »

and do NOT get the diamond plate floorboards. They're all hype. I saw one fail at over 140 mph (car used to only top out at 140, but he added naws), it probably hit some bystander in the jugular. The guy was a trooper though, he never let out of the throttle, even with his car falling apart.

also, protip: DO NOT race Johnny Tran for slips. He's got more than 100 grand under the hood of that car.

Take a picture of it, I'll be able to tell you a little more about it. I would say you will start making full power below 5k, probably around 4k +/- 500 depending on the hotside. Beautiful little turbo that will make more power than your motor will hold, sounds sexy as fuck and hits hard starting around 1 bar

shanerv · « **Reply #11 on:** August 07, 2010, 05:53:37 PM »

I will take some pics later. but it has the 18cm exhaust housing.I used to have a hy35 on my b18 hatch thing was a freaking beast!!! but that had a 9cm exhaust housing on it.

don't forget I need nawsss the two big bottles. so I can win by a inch or a mile cause winning is winning

BoostedSchemes · « **Reply #12 on:** August 07, 2010, 09:40:41 PM »

shit son the 18cm will do ya just fine. its a middle of the road housing for the turbo and panties will split at the seams in that car fo sho. fuck taking pictures till its strapped to your slutwagon.

brine04 · « **Reply #13 on:** August 08, 2010, 01:21:15 AM »

I have an 18cm h1c on my lsvtec and its not bad. would rather have a 12 or 14cm on it.

HiProfile · « **Reply #14 on:** August 09, 2010, 07:29:51 AM »

From most accounts, the h1c is a bit laggier than the HX35. I know on a b16 the hx35 will get you boost by 5k, and a solid 10psi by ~5500. So figure a bit lower for a gsr. A 12cm housing would give you a decent powerband, but an 18cm may net better times at the strip. The 21cm would probably be too big for a sub-2.0L motor, at least concerning drag times.

around when does your lsv really start to make boost and pull? decient dd?

plans are to slap this turbo on and finaly have it tuned to about 15 psi I have head studs in the motor so it should be pretty safe. looking for a bare minimum of 300whp dd and 350 for track days which don't happen to often.

Full boost at 5500.

cool thanks for the info. I will try to post a belated build thread when it's all done

h2a · « **Reply #19 on:** August 09, 2010, 09:11:39 PM »
