Opinions on the Holset HX40 Turbo

[wheelhop]

I also thought I heard a rumor that the housings are getting hard to find as vendors are starting to run out. Might want to check into that.
NOpe. The carbon steel ones. But the SS ones are not. They look much better than my rusty a$$ housing.



...The difference between us and a herd of wildebeasts is our ability to reason our way away from the cliff. There's nothing wrong with any turbo that achieves your goal, no matter how many choose a particular brand. You don't HAVE to act like an animal. Good thing no one holds it against one if he/she does. Another human trait.

They are priced right, but I don't think it'd spool up by 4k on my stockish 2L with 272s.

I was thinking about the HX35 with the "shitty BEP housing" but where can I get an HX40 with a billet compressor wheel?

I hope you're going for an hx40 with the bep housing. the hx35/40 with the bep housing is not going to do what the scm6176 will do. I doubt the suggester even knows what the hx35 turbine wheel is capable of with certain a/r. However, I don't know many who chose the p-trim wheel (scm 6176) and look for a bolton situation. In such case where bolton friendly is most important, along with spool speed, the hx35/40 with the bolton housing will compare well for flow and outspool the scm6152.

If you're looking at the best flowing scm61, I suggest the straight hx40. It spools to 20+ psi before 4100rpms and flows as much as the scm6176. There isn't an scm6176 user that can claim that spool speed and the same results at the wheels.

Wheelhop, do you work for Bullseye?

Hmm, I was fine with the ~4000 spool of C3L1CA's FP3065, that's kinda what I was wanting. My old car had a Buschur 20G, it would spool around 3600!
My goal honestly would be that magic 400awhp on a dyno dynamics with E85 on a stockish 2.0L. I also don't like the idea of buying a turbo twice. 4000rpm spool is ok with me. Suggestions everyone?

I was thinking
Holset HX35 with BEP .55 BRAND NEW
or HX40
FP3065

...uh thats it...

[MustGoFaster]

E3 16G + 75 shot?

[Halon]

You could reach that goal with a 50trim on E85. If you're bent on going Holset, then just find one that flows a similar amount of air as a 50trim.

haha, Yeah, but I want something I can get more out of later.

Come on Kevin.. Just go with the hx40 with the .55a/r. Just watch the end of wheelhop's video.. That thing spools fast as hell for what it's capable of. I don't really see how there is this much debate about it. And same to you Kerry!

Why is my name brought up again? Kevin ride in my car and tell me if you like the BB scm6152, you will!

Hx40 w/ bep .55 a/r housing will spool 20+ psi by 4Kish. The hx35 will do 400awhp easily especially with e-85. And give you more room. But you may want more room than 500whp, right? It depends on how much head room you want really.
