Its been a while since I'd looked at/played with Holset turbos but the way I remember them HX35s and HX40s, if not even HX50s all look externally almost exactly the same- HX35 compressor housings are huge for the power they make. Its the wheel sizes, and of course the tendancy of the turbine housings to get bigger and bigger as you go HX35, HX40 and above.

Alright guys here are some pics of the prep work and some parts and what not.
I will measure the turbo for the person asking for that info, and the Wolf is one of the best engine management that ive worked with and tuned with amazing results. Sorry guys im new to this forum game so heres the link to the pics

Looking good so far.
What tranny are you looking to use and what times do you think you'll need to be competitive?

I was just about to ask the same Q, What tranny are you guys gonna use ? the rb25's will not take the abuse in the drag

SmigzyGTR · 27th August 2008, 08:37 AM

Fook me thats big LOL, i stand corrected, TBH its the first time I've heard of them.

I noticed a bell housing for sale on Yahoo Japan to adapt the Mk4 Supra gearbox too a RB26, that would do the job if you could find out who makes them

max power rb · 27th August 2008, 12:17 PM

well as far as tranny goes, we are going to use the rb25 tranny for the initial break-in and tuning than after every gear is shattered, LOL, we will be installing a dogbox race transmission that was actually for a RX7 (modifications needed, 3rd time installing one of these). Believe it or not we are also going to customize the rear end with a Mustang rear because i doubt the rear end we have now with whatever LSD i might have is going to hold the power and abuse. (lets hope the muscle guys dont know about that hahah)

Lou Rob · 27th August 2008, 02:58 PM

Will the car you are building be competing against brent raus eagle talon and the awsome mazworx's sr22vet powered s15 as they are both high 6's capable and run constant low 7's ?

Benji406V6Coupé · 27th August 2008, 03:52 PM

good luck with the build!!...hang on...tweenie said he was over in the states...

you guys doing your own mapping etc?

keep us posted on the holsetts...some guys in the UK use them but little is known on the whole.

max power rb · 27th August 2008, 04:13 PM

we do all mapping/tuning ourselves on all cars, almost a two week waiting list to get your car tuned by us. Anyways i definitely will keep you guys up to date with what happens with the Holset as well as the use of the Wolf engine managment.
Lou Rob--- we will probably not compete with Brian Rau's or Maxworz due to the fact that we are aiming to create a Super street/Drag car unlike them who have strict drag car with heavy body modifications. We will be actually utilizing full body weight but of course reduce all the weight we can and keep it looking like a street car-- extreme "sleeper"

freakazoid3 · 27th August 2008, 05:39 PM

looks like a very interesting project, good luck on the build, allthough I think you wont even need it

And making a sleeper ones every while is even better then a full drag car I suppose

thanks for clearing that. All the best with the project

due to the fact that the rb head was just sitting there on the bench, already port and polished, i decided to skip going to the gym after work and literally built the whole head (assembled everything, made sure of all clearances, and installed the cams + the gears) now the head doesnt have to sit there on the bench all unhappy. I will be finishing the complete balance of all rotating assembly this week hopefully (busy building 1100 hp Supra). And still waiting for my JUN head + main studs to come in.

plumwerks · 28th August 2008, 03:03 PM

Is the supra your as well and where are the pics of all this niceness.

max power rb · 28th August 2008, 03:31 PM

supra is not mine, it is one of our best customer's vehicle but due to the fact that one of his other car that we built as well, 730hp rx7, was stolen, he asked us to not reveal this vehicle to anyone. trust me i want to take pics and put in my portfolio in our shop but i have to respect the customers requests.
