My turbo packed up other day on my frst. Im running a stage 3 1.9 cvh soon to have mappable ecu. I have a t3 at the mo running 222 bhp @ 13psi. Should i upgrade to a t34 of escort cosworth or stick with t3 which is off 2wd cossie. I intend to up the boost soon and go for more power.

 

Upgrade to T34, but just have your compressor housing machined out so you don't have to buy new hoses, and it's cheaper.
Don't forget a 360 bearing and a step gap seal at the same time.
