Hks T51r Kai Vs Trust T88-34d Response?

[PJ.]

I'm sure this topic has probably been flogged like a dead horse but I am possibly looking change to a T51 from a T88 depending on response.

What I'm really asking is, if anyone has had both turbo's, for some input on the difference in response.

Basically, is it worth spending the extra $$ on a T51? I'm refering to the BB version. Currently have the T88 on a 2.2L SR20. It starts making boost at 5 and the gate cracks open at 6,000.

I know there is a world of difference in technology between the 2 turbo's, and I've thought about changing the exhaust housing on the T88.

Your experiences/thoughts?

I would think that the mass of the turbo blades on such large turbos would be the main factor of their response and not so much what bearings they use

AFAIK the only difference between T78 and T88 is the exhaust side, so essentailly you'd just be making it into a T78 if you went baout it this way

Me thinks he was asking the difference between an HKS T51bb and a TRUST T88

IIRC the KAI is rated below the T88-34D.

Either way, you have a dyno queen.

I'd just leave the biggest turbo on there. It wont be good for much else either way/turbo you choose

Well to me dynos are for tuning, but for the record it made 521hp @ wheels on 29 psi.

It has run 132mph making 481 hp. I wanted better response still using a big turbo, and know there are worlds of difference in technology between the HKS and Trust units.
