As above my turbo has given up the ghost on the xr2 turbo (cossie t3) and was considering upgrading to a T34 BUT would I notice a difference / is it worth it on my spec engine???? Dont want to spend the money on one if i dont have to! Current spec is as follows:

1650 CVH
Cossie T3 turbo
Fully balanced and blueprinted
Blydenstein gas-flowed cylinder head with silicon valve stems
Low compression pistons (7.0:1 CR)
OFAC management
Escort Cossie Group A K&N Filter
Spec-R oil breather system
Ahmed Bayjoo Phase2 conversion
Beige fuel injectors
IB5 RS1800 Fiesta 5-speed gearbox
AP Racing clutch with uprated road/rally cover plate

It peeks at around 15psi but the turbo seals are foobered!!!!

I am considering going cossie management in the near future but not planning on upgrading to anything else (was going to go 16v but spending money elsewhere now!!)

Cheers
Chris
