HX/HY35s are nice and all, but what about H1Es?

65ShelbyClone · Mar 27, 2007

The HX/HY35/HE351 Holsets seem to be the bee's knees with a number of smller displacement engines like our 2.3s, Mitsubishi 4G63s, etc.

However, what about the step above that? I'm still enjoying the euphoria from getting a "mystery" H1E for far less than the HX35 going price. It's in spanking shape with minimal radial play and zero thrust play.

I know of one person on turboford using an HX40 on a 2.5L Ranger, but he's the only one. Is onyone here using one or know of some other head case that's running a big hairdryer like this?

yeah defintily keep your eyes open for the other turbos of the same size. We say mine is an HX35 so people can relate to it. Its actually a WH1C which is the same thing but came out before the HX35.

65ShelbyClone · Mar 28, 2007

Yeah, that's something I dug up in my research on this latest one. Same as the H1E being predecessor to the HX40. However, after more searching, I'm not sure that I don't have an HX40. I saw some mention that H1Es never had wastegated housings, but the HXs do. Mine has a wategated 17cm twin scroll and a 58mm compressor inducer.

Anyway, I actually doubt anyone on stangnet is using one on a 2.3, but I had to ask. The Mitsubishi crowd seems to like the 35s and the 40/35 hybrids, so I don't see why a heavy breathing or Volvo headed 2.3 couldn't use one.

I'm certain anything used just for drag racing the bigger turbo is a good choice. Using a 2step to build boost its not going to matter about lag time.

65ShelbyClone · Mar 28, 2007

Yeah, I saw an in-car video of someone's Holset-equipped 2.3 notch on the 2-step. Took about 1 second for the boost gage to nail 15psi.

I think the HX40's bigger T4 flange and housing should be good for much lower backpressure and hopefully from that, more power. It will be laggy as heck, but once it spools that's not an issue. I haven't seen any info on the boost:backpressure ratios for HX/HY35/HE351s on our 2.3s. I have seen that the stock T3s and IHIs usually have 2:1 exhaust/intake ratios. Not that great.

I would say its mine but I run more boost and on my in car video you couldn't see the boost gauge.

My car on nitrous is nearly instant for it to build boost. probably about .2 before its at full boost.

65ShelbyClone · Mar 29, 2007

Nah, it was a blue notch. Some regular on TF or here I think. Heck, maybe it didn't even have a Holset. I don't remember who it was.

Does nitrous really spool a big turbo that much faster than a 2-step?

351wcoupe · Mar 29, 2007

well you can run nitrous+big turbo and it will spool for sure.

If you intend to run it without nitrous I wouldn't be caught dead with a big turbo and no 2 step.

so you have the 351 on your 2.3? my dad got one that he was going to put on his spirit but is second guessing his decision and i may be able to take it off of his hands, i just dont want to go from the garrett to the holset and get a whole lot of lag. i can deal with a couple seconds, though.

yes they made a wastegated H1E it would be the WH1E. There is even one forsale on EBAY. The last time I was at the truck salvage yard there where a few WH1C and WH1E turbos. I may pick a couple of them up next time.

65ShelbyClone · Apr 4, 2007

Yeah, that new one. I'v been eyeing it, but I blew my turbo budget on the used HX40.

There's even a TV__ series on there. That would be good for a 9-second V8 of some kind.
