Holset HX40 Part numbers (wheels, housings ect)

[billman]

Hi,

i am new in the forum. I have 2 HX40 Holsets but they have the 56mm inducer 8 Blade impeller. I would like to install something bigger. Do you guys maybe have the Holset part numbers for:
6 blade impeller with 60 mm Inducer and the compressor housing to fit this.

7 Blade impeller 60mm inducer and the compressor housing to fit.

Thanks a lot

My old 8-blade HX-40 was 58mm compressor. Look at Htturbo.com for info on the upgrades. Look in turbo tech for all 3 holset threads and read up like I did.

I i have 3 of them. The two of them have 56-57mm inducer and the third one 55mm. I also read all the thread 1+2 some time ago and 3 yesterday but i dont recall if the information i am searching is in the older threads and to be honest i dont have the patience to go through it again.

to make it more interesting here some pictures. I plan to run it on an Audi RS2 5 Cyl engine with a modifyed K26 housing (it is an old cracked housing machined to accept the holset turbine impeller).

I believe it is about .55 AR. How do you thing would it go on a 2.5 liter engine. Where would the small .55 AR be a restriction?

Here the turbos (i want to modify the one with the damaged housing)

I believe the mitsu bolt on housings made by Bullseye for Holset turbo's also feature a .55ar. They don't choking power until you get into the 500+whp range I believe.

Hi, i spoke with brandon and he was very helpful but i wanted the part numbers so i maybe buy them directly over here (Germany) from the Holset dealer. Unfortunately they are not able to search for custom things. So i must give them precise part numbers.

thanks
