The 35 will be good for what you're looking for. Spool a bit slow but mine was good for that power.

For 350hp only I think HX30 will be better suited. Beware though, there are 2 types of HX30. One with very small Inducer. And another one bigger. U should get the later one.

IN:49MM EX:73MM
Turbine: IN:64MM EX:52MM
Good rear specs also.
More like TD06 20G, a tad tad larger. So it would be good spec for RB20.

Cheers.

Well cant see it at the moment. its gettin shipped but Its a hx30w. Is that the one that im looking for? How much sooner should I see full boost on this compared to the hx35?

[robots]

76+ compressor vs 73mm
Is ur HX30 with anti-surge compressor ? If it is, u are getting the right one.
If not - the smaller one.

[Umbys]

Stupid question but is it possible to bottom mount any of these on a ka24de? Or are they to big ? Only looking to make 300hp.

RB25 with HX35. The ebay manifold had to have the flange cut off and angled away from the valve cover. Full spool (15psi) is around 4k depending on load and gear.

[PoorMans180SX]

I know this isn't exactly a Nissan engine, but it's in my S13.

Modified HX35 for external gate, Stock twin-scroll 12cm2 housing. I would encourage anyone looking to do an HX35 to stick with the stock housing, weld the wastegate shut, and use a twin-scroll manifold. The setup on my buddies stockblock evo makes 28psi in 4th at 3500rpm.





Engine is at the machine shop now.

I've talked to Juha abotu his setup. He wanted to keep it his special reciepe.
But as I believe its an Super HX40 with devided t4, probably pretty big AR and billet compressor wheel. Running 2.2 bars) 720hp and over 1000nm !!!

[beems240sx]

that 4g is going to be awesome. at our shop we have built multiple dsm's with them. always a great pair. i have a 2g with a built motor running a 16g with a 20g wheel bored out in the compressor housing. 20psi by 3800 rpm. going to be turning it up to 28 here soon! another cheaper setup with incredible results.

Yeah I'm thinking so as well. Is yours a 6 or 7 bolt?

Mine will be a 2.3 stroker and I'm hoping the hx35 will pull some ridiculous spool numbers.

Hey, did you tune your car? how much hp is pushing? i have the hx35 with rb25 too! i get full boost 15psi on 5k rpm.. i think is due to the crappy CX racing turbo manifold that i have..

[holslut s13]

Im glad I found this thread. Ill post up pictures later of my hx35 with a Tim's turbo. 63 a/r exh housing I hope to run with a ka24de.

im running a built 6 bolt. dont really count on super fast spool... its still journal bearing. but search holset sr20 on youtube. i have a few vids up of mine.

[robots]

15psi for 5000 is late! Check ur wastegate and rear housing AR.

Have you ever seen what they do on the stock 12cm2 twin-scroll housing?

Stock 2.0 6bolt with 272 cams at 30psi. I've never seen an SR or KA that has used the stock housing on an HX35, otherwise I would post one of them.

I think this would be a killer setup on a stock SR or build KA.

maybe is because of the shitty manifold that i have?

[robots]

Even running it on stock mani won't make it spool 15psi by 5000rpm. I doubt its ur mani.

Even if the mani is bend and leaking a lil bit?

Anybody have a downpipe for an HX35 they wanna sell?? Trying to get my set up finished

[richmond82]

love the info thanks all

If its leaking it will cause you to lose boost pressure, making it not boost as rapidly.

[godzillarb]

RB25, HX52, ebay twin scroll, twin Tial 38s, 4" downpipe to 3.25" cat back.

Impressions so far: surprisingly nice spool for such a monster. In 1st gear, boost hits hard at 5k. In 3rd, it starts spooling at around 3.5k with 10psi (gate pressure) at a little under 5k. I still haven't driven this thing much or adjusted the tune, but it should get better with an electronic boost controller and some timing. On 10psi at 7200rpm, the z32 maf was reading 4.650v.















Hood didn't close, so I cut out a hood core support and threw in some shorter engine mounts. I think there's like 1/2 a millimeter of clearance from the top of the turbo to the hood skin.

IIRC, my setup made 15psi by 4300 in 3rd. Ebay non twinscroll manifold. I use power fc to tune. No clue on numbers since I never dyno'd it.

[Axel18]

Just for future reference, HY35 HE341 Holset on a SOHC KA24e, hit 310Hp/Tq @ 14 Psi. Full boost around 3200-3500 RPMs. Currently drifting and its just lovely.

Dont know if this vid will show some of how it feels...

[jerryjohnson]

anyone with hx55 on ka-t?

[PoorMans180SX]

This is my twin-scroll hx30, it still needs some cleaning, machining, welding and powdercoating.







Size comparison to my hx35 compressor cover.



For those of you that don't know, this turbo compares roughly with the 2860r. It has a 44mm inducer, compared to the 47mm inducer on the 2860. But the exducer is significantly larger at 73mm vs 60mm for the garrett. This should make it better at higher pressure ratios, and the 65mm turbine flows a lot more than the little 54mm on the Garrett. Even with the bigger wheels, it should spool faster in the twin-scroll housing. There is an SR20 in the UK making over 350 to the wheels on this turbo.

now thats a shitty manifold

[pantherballhp]

has anyone ran a holset on a single cam? I'm looking to possibly throw a h1c i've got laying in the shop on my s13.

[240dream]

Im looking for a hx30 on my bone stock ka-t. But haven't found any feedback on it like quick spool. I've heard the hx30 is to small? My setup now makes 270hpit at 7psi so not looking for much more power.

[frankist]

i have an hy35 on a ka, starts boosting around 2.7 and full by around 3200. works pretty well imo. I do have an extra hx35 if anyone needs to experiment, just pm.
