Thanks for the reply.

I bought the car with the damaged turbo. The turbo i took off was a maram shafted, Group A T34. I presumed the hybrid t34 would be the closest replacement. I did go for a .55 rather than the original .63.

I had it on the rolling road and the operator said that theres plenty of fueling, just replace the turbo..

The chip is a GGR chip and just says T34&blues on the top...

I have no idea about the amal valve or preload. What should i be checking for/changing?

any info would be appreciated.
