Im starting my project, its a 95ex h2b turbo. I've done a vitara d16 setup in my old hatch but i figured id try a h22 now. I've done a good bit of research, ill be using eagle rods and cp (9.0:1) pistons. The stock block should be able to hold around 400hp (which is my goal, so i wont be going past 400), itll be tuned on crome pro for sure. Anyways, im looking at a couple setups, gt28 or gt30, precision sc61, or a t3/t4 with staged wheel and probably .63 trim. I think the gt or sc would be more effecient though, i have a feeling it would be pushing the t3/t4 far to make 400hp. The second part is if you know the exact part number that would be great: like you have gt28 but then theres the numbers after that, that depict a/r's and such. Any help is much appreciated!

i dont think you can use cp pistons in an h22 block. the sleeves are coated with something...i cant remember what. but you have to use mahle pistons i think if youre using the stock bore. sc61 would be nice.

i would suggest a gt3071 with a .82 hotside as seen in the link im going to post up for you you can probably find this turbo somewhere else cheaper but this was a quick link i could find to show you what to get this turbo is capable of about 450-475whp if pushed to the absolute limit but i think this would be the "best" option for that motor as it would spool quick and not fall out of boost between shifts due to it being DBB

if your looking for something cheaper or you plan to make more power in the future let me know as this wouldn't be the turbo for that and a gt28 anything isn't going to make 400whp without being pushed EXTREMELY hard and the only one that would do it if pushed that hard is the gt2871

sc61 is way more than he needs for 400whp you would just be getting extra lag for nothing

and i think you do have to use mahle pistons but they are really good pistons
they are what most 1.8t 20v VW guys use

The sleeves are FRM, and yes you will need to use Mahle pistons. A GT28RS won't make 400 anything, it's not capable. There are other option though. The GT3076R is a great street/strip turbo, especially on the H-Series and it will flow up to 525, but at the limit.

under $1,000
t3/t4 60 trim stage 3 or higher wheel
60-1
holset hx35 or hx40 or the hybrid hx40/35


over $1,000
gt30
bw s256 an s258

Thanks for the input guys, i did not know about not being able to use the cp pistons in a stock block. I looked up the mahles, and from what i can gather i need the gold series for "factory fiber reinforced matrix cylinder bores ONLY"? (<can someone confirm that)and ill use the eagle rods with those.

fatboy1185

holset hx35 or hy35 ?

HamiltonRex

a bw s200 series would be nice, go with the extended tip turbo if you can swing it. I love my s258. It looks like they have some new s200 series turbo's out now too

tony413

sure with a 12cm^2 or 14cm^2 turbine

z6hatchboy

I was look at those the other day, but also in the 8cm housing (which is useless) but anyways. Are these the same exact ones of the cummins?

The Mahle Gold series is the piston to use with stock FMR cylinders. Make sure you have them honed as specified as it is critical on these. The cylinders are definitely strong enough to take 400 +++ whp. A GT 3076 can make mid 400+ and you will be amazed at the torque and street responsiveness.
Good luck!

The GT3076R is efficient up to 525whp.

tony413

yup cummins uses holset exclusively i haven't seen them use anything else to date. no matter which HX35 or HX40 or HX50 you get, you will always have a large choose of turbines to choose from .

my personal reason for holset over alot of turbo is the performance per $ it's unbeatable.

z6hatchboy

They're t3 flanged too right for the manifold?

z6hatchboy

How do they specify it be honed or to what spec?

boostfreak2285

i was going to recommend the same gt3076r

tony413

yes you can get them in a t3 flange

For a cheap, effective setup, i would just snag a 60-1 and call it a day. That turbo wont run more than about $750 and will easily make 400whp on your H2B. There are other options available, including the Holsets mentioned above, but this would be my personal choice. That is unless you have a decent budget for it, in which case i would look at the BW S256/S258

z6hatchboy

Whats the spec i should look for on the 60-1. I looked at the bw's but those are deff out of my budget haha. The holset is looking good so far and if the 60-1 is around 750 then these two are looking like the choices for me probably

spoolin turbo s

the holset is definitely your best bet if you want to do it cheap and with a h22 and they came with a 12cm turbine housing so you wouldn't have to change that and that would save some money and there compressor map says it can flow 60lb/min
A full weight 1g eclipse has trapped 132 with this turbo which is about 550-600whp when pushed to its limits
they come off of a 99-02 manual dodge Cummings diesel truck.

You could get the Holset; however, I personally haven't ever used them. I have run a 60-1 on my GSR for a little while, but not enough to have a real good opinion on it. Either way, Holset HX35 or 60-1, you'll make the power you want and still have good streetability. Having said that, i would still lean toward the 60-1

tony413

im still going to back the HX35 or hybrid HX40/35, because of price, cost of upgrades, and availability of parts, and performance, its the best bang for the buck. you can run upto 600whp+ without stuggling

z6hatchboy

thanks for the input guys, its really great. That way i dont spend a ton of money trying out turbos haha. I still want to know what up the honed to spec with those mahles. The only thing that would matter is the p2w clearance and maybe the cross hatch right?
