Holset HX30
Hi well i'm planing on putting this turbo to my car(Mexican Stratus turbo 2.4 dohc engine 4cil) i want to push 300whp on dd so i want a decent spool. Can anyone tellme if the HX30 will be a good option for my goals.?
Congrats for such a nice forum. I wish in Mexico someday we have a forum like this.
Thanks in advance.
Carlos.

Why in Mexico? This forum isn't just for American's/English Speakers, though I'm sure many people on here want it that way. Anyway that turbo should do nicely for the size engine you're putting it on. I don't know the projected spool time.

So anybody here have any experience with such turbo HX30 ?

Re: Holset HX30
I'm the only one.
I already told you what I know on the jyturbo list.
Ask Pikas said (he's the guy I send people with Holset Q's to) he's looked for HX30 and never seen one.
I doubt there are more than four people on this forum running Holset HX-series turbos, and it's probably three HX35s and one HX40 if memory serves.

Re: Holset HX30
The HX30 is suitable for engines of up to 5 litres capacity requiring up to 0.35kg/s of air at 3.1.
Aimed at medium duty applications, the HX30 is a well proven turbocharger on many
4 cylinder automotive, bus, agricultural and industrial applications.

Re: Holset HX30
my friend either has an hx 30 or 35..don;t really remember. it spools up surprisingly fast for that size turbo. made big power on his d16 mini me swap...problem is that i couldn't find any rebuild kits for it..i tried the standard t3 bearings, and they don't fit.

Re: Holset HX30
Whitey, turbomustangs.com is a good place, a number of those guys are very savvy. Pikas haunts thirdgen.org and a number of mailling lists. Everything is primarily T3 or T4 flanges, and there are no ARs per se as Holset uses the (far more accurate) cm^2 nomenclature. General rule of thumb for the HX-series is HX35 is going to have 12 cm^2, HY35 (I think HX30 does too?) 9 cm^2 , and HX40 22 cm^2... although you can get housings in all sorts of different flavors both from a Holset dealer as well as from the yard.
staticchmbr, I'm sure you'll find Nissan Sentra engine bearings don't fit into Honduh engines, too. Yes, this makes no sense and is very confusing! I have no idea why it is done this way. I have asked for help with this problem, and people recommend I order parts for a Honduh instead of a Nissan
I can't understand why this ---- doesn't just fit right in, or why I should find a Honduh dealer... 
I'm uploading HX30 vs .60/.63 T3 pix now from my phone, hang a sec guys. If they aren't up in ten min I got rushed for time before work + it will be tonight approx midnight EST.

Re: Holset HX30
Alright, the pics are a bit shitty, but what do you expect of a camera phone?
Physically, the turbos are almost identically sized in respect to outside dimensions. Pretty petite package.
As far as the wheels on them... turbine wheel on the Holset is slightly larger, probably equivalent to a "stage 2" turbine found on one of the T3/T04 hybrids. The compressor wheel, right at the entry, is pretty much the same size BUT (lacking pics this may be confusing but I'll try my best) the T3 wheel is more of a solid chunk, where the HX30 wheel is pretty shallow + has a larger OD at the base.
I found my notes, HX30 looked to be equivalent to .50 trim T3/T04E, but with Garrett GT-equivalent efficiency at 1.5+ pressure ratio. Basically, it's going to be about as good as a straight T3 "hp per psi"-wise until you go 10+ psi, and then it should start flowing pretty well. Expect 350 whp out of it, but you'll have to run some fairly high boost levels to get there. RJWaggs, keep in mind that hp is a function of tq @ rpm, and when Holset recommends the HX30 for 240 (crank) hp on a diesel... 2500-3000 rpm stationary diesel generator to be specific, which is what HX30 primarily come off of, that translates to a LOT of flow as tq is probably in the 400 ft/lb range at that point.

Yeah I'm on TM quite frequently and all I really see on Holset turbos is the generic "the HX35 is good to 350 hp"
Why is the A/R's, trims and housing types such a secret?
