Guys, n gals,

I have been looking around but cant seem to find conclusive evidence what the compression ratio is for a standard GDB STI 2.0 ltr. If you now, can you let me know on here, cheers

Just wanna confirm that it is that for the AUDM GDB Sti?

HKS Japan told us today that there are 2 JDM GDB STi models with the same engine but diffrerent comp. One is 8.5 and the other is 9.0 Trying to get some info from HKS on their best setup for Simon's turbo.

Regards,
Mao

Cheers Rossco

I believe the Audm Wrx is 9.0:1 and our Audm STI is 8.0:1......

I'm going off the literature I have, happy to be corrected if it's incorrect.

STI comp ratio is definitely 8:1
