Rb25Det & T88-33D

[RNS11Z]

As some of you may have read in my for sale post, i recently installed a Trust T88-33D. Front housing size im not too sure but when i checked for the exhaust housing size the numbers 1.5 were stamped inside. So im guessing exhaust housing size is 1.5!

Comparing it to my old Garret Turbo which was a .82rear housing it comes on boost only a few hunder rpm later. I thought i wouldnt be on boost till 6k but i was completely wrong. I havent tuned it as yet but will be hopefully shortly. Im only running 1.1bar at the moment and it feels so much stronger on the st then the old turbo. With some tuning it should come onto boost possibly even earlier.

Does any one on here know of any else using a T88 on a Rb25??

Also were can i get more specs on Trust turbos as i have tried searching through the net but to no avail.

Thanks

Just thought i would post my 2c for people who thought about installing such turbo onto there car.

I will try and attach a comparison chart, as for compressor maps, good luck as I havent seen alot from any performance japanese turbo companies.

What garrett turbo did you have?

Also, just wondering why you would put a turbo on that you thought wouldnt make boost until 6000 rpm?

If you want to bring it on boost earlier, try fitting a split pulse manifold, as the T88s were designed for them.

There is an article in an old hpi mag about a top secret GTR with T88-34D, it made 'more than 1 bar' at around 4500rpm and 430odd rwkw at 1.9 bar boost.

Well i was told it was a Garret Gt35/40R by the previous owner. But i dont think it was. Im guessing it was more a Gt35 with .82 rear housing.

Thanks for the chart Steve.

Also i had been told buy many people it would be on boost before 5k. It was just my suspicions. The car does make 1 bar of boost before 5k aswell.

RNZ11Z,

i believe the GT35/40 and the GT35 are both the same.

if u can tell me the part number on the centre cartridge, i'll tell you what turbo it is.

Also, it should have the A/R stamped on the exhaust housing.
