Holset turbos

[MATTs14]

Im interested in the hx52 for 130 if you can get more. My buddy has a supra and is looking for and upgrade lol. Let me know if you can get them. My email is mattamus240(at)yahoo(dot)com

[Cjmartz2k]

Yup, except for USPS. I'm military, so we have APO addresses. They charge the same amount it would cost to ship to across the country, but it just takes longer to get here. Just make sure it's not last class parcel post. I had some tires sent out here and tried to save a couple bucks. 2 1/2 months later, my tires showed up Priority Priority took 8 days for the last turbo we ordered (HX40) to get here and it was $38 shipping. You just have to fill out and extra couple lines on a customs form, that's all.

First dibs

[MATTs14]

Of course lol. If youve got more than one though sign me up. And cj didnt you have a hx35/40 for sale not too long ago or at least a 40 exhaust housing? INterested in that

[Cjmartz2k]

I sold it, and I'm using the 19cm T4 ex housing now, but I think I might still have the 16cm T3 housing sitting around somewhere. It's kinda small though. We put one on a RB26 and it's strangling it. It' might be good for a RB20 though if you wanted to go full HX40.

[RB24D]

Ill try to find out how many hx52's he has an e mail everyone this pm .

[SullivanRacing06]

i used a holset hx35w on my rb22 with the stock t manifold, i ran a -3 feed line and -12 return, internally gated at 20-21 psi, hit full boost around 4k, good high rpm turbo, sorta boggy around town but performed amaizing for 150 shipped!

[BoostFab]

20lb of boost at 4k rpm is great and plenty in the powerband for a stock manifold. with a better flowing manifold, i can see full boost hit faster.

[RB24D]

Just spoke to my guy he said he can get as many core's as I want .He is also checking on new and rebuilds.E mail me @ [email protected] and let me know what you want and I will find out for you .

[Vetal]

Which of Holsets would make 550hp and will spool up as fast as possible? I have CA18 so it's a big issue for me

[Cjmartz2k]

Your trying to make 550hp on a CA18?!?! Wow. Double wow on hoping for good spool. If I were you, I'd get the 7 blade HX35, get close'ish to that number and have something still streetable. Your not going to have a quick spooling 550hp turbo on a 1.8L 4 banger. It's just the nature of trying to make big power on a small motor.

RB24D--I'll email you when I get home.

[Vetal]

yepp, I know, can't have boost from idle on tiny motor. But I'm crazy on dragraces so I want a bit more power, need to go 11.5s at least (now 12.8 @ 112). And seeing there are 650+ hp CA's these days in Europe gives me hope it can be done. Sweden guy makes 577whp with GT3582R and spool is quite acceptable So if it is true that HX35 will spool better, than there is a hope

Now I have Evo III turbo from Mitsu, do you know if there are housings that have the same flange so I could bolt it to my manifold?

Also where should I look for some HX35(if it will do 550hp)?

[Cjmartz2k]

I am really surprised about CA's doing that, but awesome! A HX35 would certainly spool better than a GT3582r (by a lot), but it won't make as much power. I can tell you a 7 blade HX35 would spool by 3.5k rpm or less on an RB25 and make at least 450rwhp if you turned the boost up a good amount. The DSM guys are running low 11's at 132mph on the 7 blade, but they are AWD.

Funny you mention the DSM bolt on housing, but I'm a little confused which flange is where. You need the ex housing to bolt up to a mitsu flange on the ex manifold? If so, they do indeed make a very popular housing that comes in .55 a/r and .70 a/r for the holset that bolts up to a stock mitsu manifold. You'd still need a custom downpipe made though.

[Vetal]

I was surprised too, and decided if others can do it, I can aim for 500hp at least Here's his thread, take a look. I like such builds when bags of money are not dumped into the engine but it performs - [email protected]://sxoc.co.uk/vbb/showthread.php?t=375692Hmm, 134mph was achieved with GT30R by this same guy... You say DSMers get only 132 from HX35... Not very impressive then?

Here is my turbo, MHI Evo3 16G http://www.roadraceengineering.com/eclturbos.htmNo problem to make a downpipe at all... Just takes time

[KC240RB]

Can I run the stock exhaust manifold with a HX35?

[KC240RB]

I forgot it has to be externally wastegated... D@mn.

If he trapps 134 with a GT30r, he must weigh less than 2500lb's! The DSM guys that ran 132 were at full weight (3100). They run slower times with GT30r's. Also keep in mind, an HX35 will probably outspool a GT30r, but the main thing that I'm saying here is that they are the best performing turbo out there--it's just that they are so damn cheap AND they are awesom performers.

[DriftingisLame]

The s13 will trap higher anyways, due to the weight advantage, and the fact that they are 2wd. A trap speed is not a very good measure of power when comparing two completely different chassis.

Cj, its nice to hear you're so confident in the holset turbo's performance, as I have one in the mail currently. I also have an rb20 and somewhat high power goals in mind. High power and quick spool are never easily accomplished on the Rb20.

[MATTs14]

What kind of power are you looking for?

[DriftingisLame]

Me?

I'm looking for a modest 350 whp on my first tune. I think thats quite a bit for the rb20, and for an s13. However, I'd be shooting for more if I had larger injectors. I have 440cc injectors currently, and I think the highest safe hp level will be around 350. I'd imagine I'll need to run around 15 psi to achieve this, but I'm really not sure.

How much boost are you going to run, Matt?

[JDMkalevra]

whats a good desent turbo for a ka20

[Jesse J]

Are all Holset HX35 compressor housing outlets 2.25" v band? And all HX35 exhaust housing outlets 3" v band?

I'm trying to get all the parts I need to finish my setup, but I am still waiting on my turbo to get here. Trying to get my car back on the road asap.

Thanks

[Cjmartz2k]

To be honest I've never even heard of a KA20, but I'd guess HX35. What are your hp goals? HY35 might be better. They do make smaller holset's, but I don't know anything about them.

Here's a couple of vid of my old HX35/40 hybrid if anybody cares to see.

This swedish guy's had a lot of high Hp CA vids on youtube for a while now, but just recently achieved his 577rwhp tune. I found the video to be pretty much awesome...

I believe its norris designs who has the 650ish hp CA18 in europe. They achieved somewhere around 187 mph with a few issues a while back, wish I could find the damn video

Big props to the little CA

[MATTs14]

And btw DriftingisLame, Im looking for 400whp out of my 20, with some cams and a carl h tune. 650+ injectors, maybe some head work, z32 maf, holset hx35, 3.5 or 4 inch downpipe and the 6boost manifold. Will probably be running an rb26 intake with the itb's as well. Not sure how much boost i will run right away.

Also does anybody have any pictures of the Bullseye performance housing and how big is the vband on it if i get it non wastegated. And i have the 8 blade hx35. Still good for 400whp????

[Vetal]

Cjmartz2k, what do all those housings mean - bolton, bolton BEP, stock, bullseye?

[MATTs14]

bep simply means bullsyeye performance. Look on tims turbos and you'll see what he means. Bolt on is simply a reference to those. Can anybody answer my question about the 8 blade hx35 and 400whp???

[Cjmartz2k]

The 8 blade should be good for 400rwhp, but I wouldn't think a WHOLE lot more than that at reasonable boost levels. I think the biggest limiting factor with the RB20 isn't the displacement, it's the head, so your head work and cams sound like a good idea to me. The "bolt on" or "BEP" housings have a mitsubishi flange and will not work on a nissan. I believe all the HX35's come with a T3 flange which is what you have stock, but you might need to put a spacer on it if you want to run the stock mani. I did, however, bolt an HX40 up to a stock manifold that was sitting on the floor just to see if the compressor housing would clear, and it did. That was an HX40 though.

Those vids are damn impressive. Did you see how bad that thing was compressor surging BTW? That is compressor surge, not that noise people whine about when they let off the gas from boost.

[MATTs14]

well thats rather disappointing. Im not sure i will be getting head work but i am getting cams for sure. I guess the 8 blade will spool faster. I will eventually make an hx35/hx40 and bolt it on my rb25 later on. So you do think the hx35 8blade is good for 400whp though?

[DriftingisLame]

I'm confused Cj, after reading this....

"The 8blade hx35 has a 56mm compressor inducer. This is found on 1995-1998 cummins manual pickups. The compressor flows 52 lb/min according to the compressor map. The bolton BEP housing (0.55 a/r) is enough to push the limit of the compressor. There's several 500whp 8blade hx35 cars out there with the bolt on housing. It reaches 20+psi by 3500rpms in 3rd with 272 cams. Smaller cams would equal a faster spool speed in most cases."

What makes the rb20 not capable of achieving the same power levels? Are you saying that it wont make this power without running obscene amounts of boost, or are you saying the head is that much more restrictive than a 4g63 head? Keep in mind we are running the stock divided 12cm2 housing instead of the smaller BEP bolt on housing, this should give us a power advantage at the cost of a few hundred rpm of spool.

There's a couple of 500 whp RB20's in the SAU dyno thread that have stock heads, cams, and bottom end parts. Granted, this is at 23-27 psi boost. If you'd like me to link you I will. I'm not dissagreeing, I just want to know what you know lol.

Thanks

[Cjmartz2k]

From what I have seen here on Oki (and that's pretty limited experience with RB20's) RB20's take a bit more boost to make big power numbers with the same turbo. Also, of course, they are going to be lagier compared to a RB25 with the same turbo. I raced a similar R32 as me with the same To4e as I had, but he had an RB20, and I had an RB25. I was running 1.3 bar, and he was running 1.5, and I pulled him up top, all lag asside. That's pretty much my only experience, so take it for what's it's worth. Also, for "I read it on the internet" information, I've heard on the SAU thread that they thought the head was the limiting factor. My GUESS would be the RB20 head is more restrictive than the 4G63 head. Very true what you said about the stock holset housing helping up top though. The spool difference would be negated if you are running a devided runner manifold also, since that bolt on BEP housing they use is single scroll.

Matt- 52lb/min would be AROUND 520hp at the motor max, but at who know's what boost. 12% drivetrain loss would around 60hp, so call it high-mid 400's? Than knock 20-30 off for not running 2.2 bar and I'd guess low-mid 400's at the wheels on the 8 blade. That's a whole lot of bench racing though. I have a HX35 compressor housing and wheel sitting around somewhere. For sure 400rwhp though. Let me count the blades on it and I'll get back to you to see if you'd want it.
