I was wondering how the hx35 would work on are 3.0 litter motors . Would their be a lot of lag. What kind of power could I expect at oh say about 15psi?. What rpm do you think I would make full boost by. and where would it start spooling at. I seen a article in sports compact where they put one on a 2.4 Ka 240sx. It showed the power start to sky rocket at about 3200 rpms on the dyno graph. and at 5000rpms it took t it to 266whp from the stock # of 136. No other majot mods other than turbo. this was do at 12psi. Their torque was at 271. Well how would it compare on are 3.0 VQ or the Vg30

How are you planning to mount this, what exhaust mani are you running, custom? I predict spool will be ultra quick since this is popular with the DSM boys as a 16G competitor/alternative.

I have custom manifolds and I will have to change the flange. But im wondering how its going to perform

subs1000w

probobly spool mid-high 2k range max out around 400whp the only problem is the gated turbine housing is 12cm2 which would be alittle small for a VQ but would work good for a VG but there are many different upgrades for both the housings and wheels since its used on all the dodge rams from 95-03 its in the center of turbo diesel performance

an HX40 with a 16-18cm2 housing would be a good turbo for a max looking for 500whp and they can be found much cheaper used than most aftermarket turbos and holset turbos are considered one of the most reiliable turbos on the market since they tipically go for half a million miles on a diesel before they need a rebiuld and diesels run much higher boost than most gas engines

So you are saying that the hx35 may would spool faster than my stock ct26?
I make full boost now at 3000. It starts at about 2600 to 2700.
So how about the hx40 on the vg What kind of rmp do you think it would start at and what rpms do think about 15psi could be made by?

maxmaxima91

Those stats would all vary depending on how well the setup flows. But yes, an HX35 would spool very quik on a VG. My brother is lookin for one for his honda right now. I would go for the HX40 For the MAD topend.. but thats just me

ok if i would go with the hx40 and run about 15 psi what kind of power do you thinking im looking at?

maxmaxima91

I dont know much about that turbo but if its what i think it is, i would guess. With a fairly high flow setup, on a good day, you might get 330-350 WHP Possibly more. That is just my guess. Ive learned from the vehicles ive turboed, that it comes down to the setup. So all of this could vary.

well how much boost do they run stock.IIRC its like 26.Some one please verify that for me.
And psi do they really become eff. at ?
Do you think it would hold full boost to my redline(6000)(hx40)

A friend of mine runs a hy35 on a vg30et. He starts to spool around 3k. He's got the smaller exhaust housing.

subs1000w

well how much boost do they run stock? if your asking what the wastegate is set at its around 18psi

Do you think it would hold full boost to my redline(6000)(hx40)? either of those turbos will easily hold boost to redline they have much bigger and way more efficient compressor wheels than a stock CT26 like i said the HX35 is effiecent to flow enouph CFM to support 400whp the HX40 is around 500 but like he said your setup is what the makes that decition you could make it at 15psi or it might take 25 it all depends on how effienct the rest of your setup is

From all I've read the HX35 is actually good to around 600 hp (probably bhp). The compressor maps of them are very similar to, if I remember correctly, the GT35 minus that map is much wider.

I would think the HX40 would be a tiny bit big for the our cars as they're actually supposed to handle the 700-800 hp range, from what I've read.

I'm looking at the compressor maps right now - they are kindof funky - no efficiency islands denoted, just one big island that you are either "inside" or "outside". The HX35W is good to pressure ratios up to 4.0 and about 650hp at PR 3.0. The HX40V is good for about exactly the same as the HX35W. The HX40W is good to about 800hp at a PR of about 2.75, and is good up to a max PR of about 4.25.

Keep in mind these are max values, not most efficient values. The GT35R is "capable" of about 650hp also, but if you are pushing that much air through it you are making a ton of heat and it's way out of the most efficient part of the map. The numbers above are the same sort of thing. They are the extremes of what the turbos are capable of.

So looking at it So witch do you think would spool the fastest and hold full boost to redline on the vg. Also making about 375 to 400whp.

subs1000w

im going off of what ive read on many threades on many different sites for the max whp ranges but thats at reasonable boost levels and ive seen quite a few HX35 dynos and they all seem to be in the 400whp range +-50 havnt seen any for the 40 but i know roughly what there capable of it might be alittle higher than 500 but no more than 600whp

heres a thread that discuses it alittle

as said quite a few times on that turbo mustang forum, when comparing max output from a turbo off of a diesel going to a gas engine the numbers are pretty much double. Going off of Holset's site for their current HX35, if that's true, it should handle between 200 hp and 560 hp. I've heard they can handle "over boosting" pretty well though.

That's just what I've read though.

I just finished putting an hy35w on my z31. For the $300 + time I spent on the turbo and getting it in I'm happy. The hy35 has the 9cm^2 exhaust housing vs the HX35's 12cm^2. My suggestion would be to go with the Hy35 for the faster spool. In second gear I get 10psi by about 4000rpm. 3rd is 10psi by about 3400rpm. 4th is by 3200rpm. Not bad at all but an hx35 would be worse. Keep in mind the hy35 and hx35 use the same compressor wheel so they are just as efficient. My exhaust/intake pressure ratio is much less than the 2:1 ideal limit. I had roughly 25psi of exhaust pressure with an intake manifold pressure of 18psi. This was running 13.2 @109 with a slipping clutch. Anyway, I'd be more tempted to go with the hy35 just because it spools faster and will likely provide enough power for most peoples needs. Oh, and they are easier to find because the hy35 guys dump them for hx35s.

dam that seems to spool pretty slow on your set up! what kind of compresion do you have? I know a guy can build 25psi on a dsm with a 2 litter by 4000rps
with a hx40

Bernardd

I don't think that's with the holset exhaust housing. Don't they have them modified by a dsm supplier with a housing that bolts up to their manifold?

I have to check on that thread I think that is with the holset housing though i may be wrong

Keep in mind that my car could probably use a bit of tuning. This is with 8.3:1 compression, Schneider stage 1 cams, 3" exhaust, stock manifolds. Also, when comparing spool rpms what conditions were the pulls done under? A 4th gear pull with heavy *** Dynojet rollers is probably going to spool earlier than a 4th gear pull on the road. Also, my numbers come from datalogs, not (it looked like xx on the gauge).
