    should be fine, although a high lift cam is going to help things

    it really depends on how much power your after

    Power region could be somewhere about 180-200hp.

    If you only want to hit that level of power, a 2554r is too big & will be laggy to drive.

    A GT15-GT17 is more in that range, or even an old skool Tomcat turbo.

    Could always modify the o.e T2...

    You will need a decent cam to get the best out of the .64 exhaust housing.

    Agreed, you could pick a small gt series turbo with mega fast spoolup for that power level. Logg's gtt for example full boost at 3500 and 200hp.

    Spot on advice Mart.

    A .64 rear is rather large for 180-200bhp and will move your boost threshold up to around 4.5/5k.

    What i did was pick the smallest turbo that can supply the bhp i was after and then went up one size just to make sure.

    I used to run a Gt17 on my 5, It was a nice turbo as responsive as a T2 with a bit more Kick

    As mart says Its a laggy turbo the GT2554r. When I tried one it was 4800rpm for full boost. Maybe just a smaller turbine would work OK, if you can find one.
