It has the same outlet like GTK which is 3". I was surprised to see the same spoolup like, the smaller GTK-650 (hotside / turbine wise). But backpressure still high , i might have to step up to 0.96 or larger AR . I think that this turbo will easily do 800hp@2 bars, if i can have close to 1-1 backpressure ratio.

Small updates for this year.
10mm lead wire from UK
Bosch Sparkplug F2CS - will gap to 0.4 if needed.
Arp2000 12mm headbolts
Some weight loss
And new turbo ordered Compturbo CT43 76/79 billet 0.96 AR T4 - will see how is this compared to 67mm and GTK.
Target for 2012, mid to high 9s

Turbo in position, also found some problems on Furans intake manifold,and some leaks, maybe this was the cause for backpressure, and for 67mm turbo not delivering what it should
Also measured the compresor it is 78mm with 105exducer
