So do you think that the newer version PN: 4027888 would perform better?
I have read that they flow a bit better than the part number of yours.

If thats what Holset also says, then most likely its true.
Its great and extremely reliable turbo to chose. Cant go wrong either its 2009 or newer Super.

 

[indirocz28]

Ohh I thought yours was the prior 2001 version- Hmm Nvm then I think you have the better flowing one!

I also have this turbo (6 blade 60mm in 18cm divided t3 housing) and ran it on my internally stock 1j with 280deg cams and made 29psi by 5000 rpm. With the .5L of additional displacement on the 2j I'm putting together and playing around with timing I'm going to see if I can get that down to less than 4500.

Question to the original poster:

I'm running a -4an line for feed from the stock rear turbo feed on the block, and a -10an drain. Its ran like this for 20,000km without issue. What is your feed and drain setup?

 

[indirocz28]

Yeah I thought that the true HX Super 40's were 6 blade exhaust turbine, and then they made some that were 8 blade..

Cam Ron & $upr@, where did you both purchase your Holsets?

Thanks

The hx40 comes with either a 10 or a 12 blade turbine wheel. The compressor wheel is 6,7 or 8 blade. The "PRO" "super" or whatever you want to call it,usually refers to the 6 blade 60mm inducer units with either turbine wheel.

I got mine from a guy on ebay. Brand new in box for $500 (This was 2 years ago)

I have a 7 blade T4 divided non waste gated HX40, can't find any info on it. Hard to see the serial numbers on it.

 

[Cam_Ron]

I believe that means you have the 19cm turbine housing and a 58mm inducer diameter? The only sure way to know is to measure.

 

[Cam_Ron]

I just bought the .70ar t3 turbine housing from BEP for my hx40 60mm. Should be quite a difference from the 18cm. Has anybody tried it on a 2j yet?

I just made 507whp @ 24psi falling to 21psi by redline on my 1.5Jz with this turbo. This was with 91octane gas, a single 500cc/min meth jet, 280 degree cams. I ran out of fuel pump on my 255 otherwise I would have kept going. This was on a dyno dynamics and ignition advance was as aggressive as possible given the fuel.

Here is the dyno:

 

[mikes02ls1]

Did some research and found on my HX40 it is a 8 blade 19cm T4 non waste gated exhaust housing. i want to send it off to get turned into a Super 40, but what should I do with that huge exhaust housing? On 2JZ will that housing even spool, trying to hit 600rwhp. Fingers crossed....

I'm interested to know how these spool compared to a similar sized garret or bw turbo. All over dsm forums and 240 forums ppl swear these are the turbos to go with. I chose to stick with a bw s366. But why is everyone else spending 800-1500 on turbos when used holeset can be had for so cheap. I'd rather get my facts here from ppl who have these turbos. I cant image such a cheap turbo to me more reliable, hold more boost, and spool quicker then all the performance turbos that are better designed for our applications. Can someone fill me in on this. If all this is true, then why are we still buying so many garrets pte and bw turbos. I didn't want to start a new thread so I jus posted here.

Unfortunately i dont have garret GTR turbo to compare with, but my tuner reccomends only HX super turbos on the cars they build. For track or drag. They are good everythere.
They run 2x HX40 super on theyr drag car, which is based on 300ZX. They had garret turbos before, but those were not strong enough and broke constantly. He says that theres no better turbo to chose. Perhaps HX40 Super on 2JZ spools 100rpm later than equal Garrett GTR, but it lasts forever and produces same or better horsepower as well.

 

[coobrder]

the hx40s are really, really good turbos for what they are. I'm also running an hx40 on my Volvo 2.3L 16v Volvo engine with pulse paired headers. I get full boost around 3500 rpms on my custom made tubular manifold that is pulse paired. Some people say that with a divided manifold a hx40 of comparable specifications to a GT35R will spool faster! I believe it too, yet the Holset is journal bearing.

Now the Holset hx40 comes in so many variations. I used to sell them and everyone that I've sold had a divided housing on them. They come in T3 and T4 exhaust housings as well. They mostly come with 58mm wheels, but the 6 blade are commonly 60mm as are the 7 blades. The 8 blades are 58mm IIRC.

I have an HX55 Holset that will be going on a 2JZ motor soon. It's got a billet compressor 72MM wheel with a divided T4 18cm^2 housing on it. turbo should be easily capable of 900+hp
