why external wastegating it? so you can make it fit? or just so its easier to use? That was the only part about the holsets I did not understand when using them on nissans.

what's not to understand!?!?!?!?!? external wastegate is better in holding boost creeps. everyone knows that. w/o the actuator on the turbo, making it a cleaner install.

Schweet! I saw rebuild kit online for like $60. I've been wondering if it is even possible to run the internal gate on these things. They were meant to be used on a diesel at a lot lower RPM. I wonder it the internal gate can flow enough to keep up.

nismo zilvia, the guy i bought it for had it on his rb20, and he said that it was too large and wanted something more smaller and BB, cause spooling on a rb20 at 22 psi would prolly be around 3900-4200? idk Chris would prolly know..oh and chris, thank you for talking me into these Holsets bro!!!   and its not only that i want to externally wastegate it, but my apexi manifold already has a wastegate flange  . its in a good spot too. right under the turbine inlet

**** for $150 it can spool at fukin 5k with all I care lol. From reading it I see it makes good power and the power I need. Nothing higher.Though a GT3076 is what I want but its also like 1200 or so.

My shop guy today was like, "why did you tell people about these?". I was like "I dunno, they are in the states and I'm over here. Besides, I'm not racing any of them for $ (yet  )" He was actually the one that turned me on to these. The HX35 part came from the guy in China that makes his RB manifold's personal car (er, truck). HX40 was from ebay. I think these are pretty good performing turbo's, but for me, the main draw was the price. HX35's are the throw away turbo's from the guys with cummins diesels wanting to upgrade, and HX40's are on everything from buses to boats (and generators).
I took some spooling vids today, but I haven't posted them on SF yet. Keep in mind, mines a RB25 which helps spool earlier, but I've got 4.37 gears (stock) so that spools it later. Kinda hard to tell what it would do on a RB20 in a S14 with I dunno what gears, but in 3rd, I was at 1 bar by 4k rpm and 1.5 bar by 4.4k rpm.

Sorry a little OT, but why does his gauge cluster's coolant temp plummet like that when he's on it? Mine does that too but I always thought it was because I'm using the RB sender on the 240 cluster and I never bothered changing it for the KA sender cuz I have the PFC and an autometer gauge. Does this happen to anyone else?

Most likely the reason, get the KA sender on there and it will go away most likely. Once mine was on there, it read accurately, Now it would drop if I was driving faster but not slowly, and not much. I'm curious to see a graph of this turbo, so what kind of flow it has up top and so forth... If its good, I'm kind of pissed since my manifold is setup for t4....

Hx35 seems too big for my application and the Hx25 seems to be too little for what I want.I like the Hx35 because of the power it can give you and I want something around 400 so the Hx35 does the job for me. But some say it'll spool late. Anyone with a RB20 with this turbo? Tell me how you like it. Thanks!!

Get an HY35. They're stock off a auto equipped cummins and even cheaper than the hx. Slightly smaller with (commonly) a 9cm exhaust housing. We're putting one on my buddy's rb25 because he's looking for a little quicker spool and not shooting for all that much power. I would think the hy would be a very nice turbo on a moderately built 20.

Why not just get the HX and see if you can find a 8cm exhaust housing. That should give you the spool and make it not lag so much. 10cm is way too big for a 2.0.

I've been trying to figure that one out for a while, and It has nothing to do with it being a KA sender or anything (since this is a Skyline). It also occasional flashes the door's ajar light along with the temp needle freaking out.
I grounded the ecu (PFC) to the frame with an extra wire and it went away, but it came back all on it's own a few months later. It only seems to do it free revving at high RPM (above 6k) or lower in the RPM range if I am in gear and have it matted with load on the motor. Almost like it's connected to injector duty cycle or something. I have since grounded the temp grounds going into the ECU, but it didn't help. Is there a ground on the back of the gauge cluster?As for power, I think it a little under 500 at the wheels. The stock intake and throttle body are really choking the **** out if it right now. Doing the RB26 surge tank/ITB conversion in Jan and cams at the same time, so I'm hoping that'll put me over 500rwhp (which I might be over now anyway, but I don't know).

I had a T04e on this before and made just at 400rwhp. We compared the two compressors side by side and the HX35 looked a little bigger. If I had to guess, I'd say it's good for low to mid 400's at the wheels depending on how much boost you run.

Yeah, but at what boost? I doubt many people are going to be running over 1.5 bar on pump gas. You said they were running like 2 bar to make just under 500rwhp, right? I'd still stand by just over 400rwhp at around 1.2 bar, maybe up into the mid 400's if he cranks it up to 1.5.

these turbo are made to hang out in the 30+ psi; but if the goal is 500hp less than 2 bar, then obviously this turbo will not, maybe with a larger turbine housing.

i would get the holset over the t25. Just picked up a H1E for my ka. Just a little more info on the holset turbo's.....The H series is the older brother to the HX and HY series. H series are very cheap and fairly easy to come by. Got mine fo 60$ shipped + 70$ rebuild kit = 130$ new H1E (flows 65lbs). HX series flows a little better than the H series. The HY series is the newest of the three. Slighty smaller as Bwana said. Hy35 with a 9cm housing would be good for the rb20. Here is a vid of a Hy35 (9cm housing) on a ka-t. He was at full boost (5psi) @ 2800rpm.http://www.youtube.com/watch?v=ZuMsN43L2kE

So monday work began and I have the turbo all mounted up and had the car running last night. I'll post pics later on as some may know its not just simple bolt up but once its hangin in there wow it looks awesome. To come: pics and parts needed for install.
