Look what i Just bought!!! HOLSET HX35/40!!!

[BoostFab]

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.

the hx35 can put can easily put out 500+ hp; look at the dyno graph i posted in a prior post; zer...age=2

[Cjmartz2k]

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.

how do you guys think the hx25 will do on rb lil bro ca18det? compared to t25g?

is that exhaust housing difficult to mate to? its not at all like the 5 bolt t25 pattern.

[nelson8708]

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.

So i read this thread this past weekend and thought to myself wow I can do this I have a 240 with an rb20 and my buddy had a hx35 and hx55 sitting on a shelf at home. 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.

[Cjmartz2k]

So your just doing a straight HX35 on it, right? You mentioned an HX55 as well in there--I hope you aren't trying to make a hybrid with those two!

[nizmo zilvia]

Please let us know man. Im curious to see how she runs with the stock hx35.

no its the straight hx35 as of right now its just mounted. I'm running to extreme 2 morrow to get the couplers and pipe i need to finish the install and I'm working on get my hands on a set of 660 cc injectors now I just need to find some cams.

[BoostFab]

if you all will go with vband setup, it will save you so much trouble bolting up the downpipe

[Urnext]

very true which is why i have to go to extremepsi but I dunno about the rest of the hx guys but I had to change the manifold a little bit so the compressor housing didn't rub the manifold.

[nizmo zilvia]

Why not just get a spacer? Most people get that.

[Cjmartz2k]

Are you saying it's clearing a stock RB mani?

[Urnext]

Ok here is what I need sorry for the delay in pics but my camera is bein gay.The turboa t3 flange that a 1/2 inch thick drilled and tapped this out and welded it to the manifold not an easy process you have to heat the manifold and then weld it with a good welder. Main reason i did it like this i don't have to worry about 2 turbo gaskets leaking.The stock rb drain tube bolts right upthe turbo feed is some weird British thread i kinda rigged and adapter to work that I got at lowes which is made of brass.I used a 2.5 in v band clamp for the downpipe to weld up to a 90 degree 2.5 bend for the d/pThe turbo intake is 4" so i am making my own intakeThe outlet is also 2.5 on the compressor side which also uses a v band Instead of using a v band I just slide a couple over it.Last but not least the wastegate I cut the stock bracket off the stock wastegate and attached it to the stock hx wastegate bracket. I also cut the stock wastegate rod end off and threaded it so I could adjust the rod length.Thats all I can think of right now once I got this finished up i'll post up more stuff.

Man This gives me hope in my Holset conquest...Whooop Whoop...That HY35 sounds very responsive.....Think my search will continue....Found one online for a 100 bucks think i will be purchasing it....

[Cjmartz2k]

So it won't clear the stock manifold without a spacer then I guess.

[Urnext]

I dunno about the Hy35 but the Hx you need a 1/2 spacer to space it off the manifold. I made my spacer but you can buy them online for like 30 bucks.

[TachPHD]

The HY35 has the same clearance issue. A 1/2" T3 flange will fix that issue also.

(Urnext) - Did you just keep your oil drain on top and oil feed on the bottom as it was?

What you have to have the drain on the bottom thats y its called a drain. you have to clock both housings so that it doesn't hit the shock tower and so the center cartridge is oriented right.

[TachPHD]

OK, I thought so... This way, both the stock lines will bolt right up, at least I know the oil feed will.

[Bwana]

I want to clear something up real quick.

The HX and HY have identical compressor wheels and housings, the turbine wheels and housings however are NOT interchangeable.

Basically you need to chose you turbo depending on what exhaust housing you want/need. HX for 12cm and up, HY for 10cm and below.

On my hx the feed is not compatible I had to do some modifications with and adapter I bought. The feed hole is the same thread size but the thread pitch is different. I used the stock feed line and banjo bolt but I had to use an adapter.(Bwana)thanks for the info on the different turbos I didn't know that

It's still a good turbine, but you'll probably give up a little spool time and a little hp. If you have the money, I'd do what you are doing, sell it, and get the HX.

Sucks that it happened man. Give that guy some nasty feedback.

[Cameron]

a little hp? like how much? its the predecessor to the HX35, and id say its only good for 350 at 6500..?

[Cjmartz2k]

I wouldn't even venture to guess, sorry. Info on these turbo's seems so hard to get

[Cameron]

bah, i know..

well im just going to sell it and hopefully luck up with a true HX35/40, next time..

[Coolwhip]

damn man, that sucks. Yea, give him a piece of your mind on that one.

Time for you to go visit HKS for a GT turbo :P

Atleast you found out now, and it wasn't a totally useless turbo.

[nizmo zilvia]

WH1C huh? That sucks. No wonder you got it for cheap. What are these turbos rated at because what I want is around 400rwhp. If this can do it I'll take it along with the rebuild kit.

[Cameron]

well i mean it wasnt that it was that cheap. I along with 8 other dudes thought that the turbo we were bidding on was a HX35/40.. but the rebuild kit isnt even good for this turbo. its for the HX/HY series. im sure the turbo would be good for around what a hx35 is good for HP wise, cause they seem bigger than the 35's..

idk though.. ive been reading a lot on the WH1C's and it seems that the dodge guys still like them, cause they say were built better than the HX35, even though its older, and they say that with the HX35 how it just has the Snap ring or w/e around the Comp housing, that they have heard of them completely being dislodged or something under heavy load.. this was with the HX now, NOT The WH1C they say.. i mean, im sure its a good turbo, its just that its not capable of the power i need..
