JDM WRX STI Version 3 1997

The Original EJ20K Put a rod through the block but it lasted for 98,000kms so cant really complain.
So ive built this one up, its on just under 4000 miles / 6500kms now and handling everything ive through at it very well.

Last time on the Dyno we set up the Low boost map and it managed 428hp @ 1.3 Bar/19psi. (Dyno Dynamics Dynamometer which usually measure about 12% down on Dynojet So circa 480hp dyno jet equivelant.) Then it started blowing the spark out.

So uprated the ignition and Live road mapped since to 2.0bar / 29psi Will get it on the Dyno again later in the year and see what its making
I built it to a 650hp spec so should handle the power well / "Safely" (famous last words lol)
