I just bought a holset HX35 and i cant find out what size exhaust housing I have. Could someone point me in the right direction. I tried typing in the serial numbers on google with no luck. Thanks.

 

usually inside of the housing towards the flange for the manifold its stamped in there.

 

so i see a spot that says-

E4-01-164. Underneath that it says-

12 8

does that mean its a 12 cm?

 

it is written on the inside of the turbine housing

here is a picture

 

thank you. i appreciate it

 

Also when you go to add your oil feed line, be smart don't waste money buying or making a plate to bolt onto the oil feed just buy a 3/8 pipe thread tap and re-tap your oil feed. I currently run a H1C holst with a 16 cm housing on an old school 89 lude with full head work and my spool time is around 3200 when I see just 5 pounds and after that it blows away whats left of my clutch. You'll love this turbo.

 

You could also just buy the 12mmx1.5 adapter to go to -4 [1/4 JIC] for 5-10 dollars and thread it in
