Just to add i put these graphs up as they all make roughly the same power give or take, the torque figures vary alot though. I know each engine will be spec differently. There was no point adding up a graph with a 50bhp difference.

I dont run water cooling on my T4 and never have, i have had the turbo on for 3 years aswell. I didnt run a dump valve either this summer [not enough vac take offs on my inlet] but i will be fitting one for next year.

I cannot say i have heard of many GT series turbos failing unless they have been miss used or an oil pressure drop has happened, this would cause any turbo to fail though. Like Mark and Rich have said they need water cooling, a dump valve, and dont like ALS if you choose to ignore this, then thats your own fault.

Steve - Many people are using the GT series turbos and no problems. Yes they have to be water cooled and yes you have to run a dump valve but you would be foolish not to on a T4 as well - certainly the dump valve anyway.
Run both at present and wouldn't change that

Mark,that's very interesting.I know u use a lot of GT turbos on your big bhp conversions.Cyril from South Wales has a GT30 on his escos.

How different is the r/b T4 compared to the "normal" T4 in terms of coming on boost etc?

Vince has offered me a very good deal on a normal T4, would it be worth spending the extra on the r/b one?
Anyone?
