I have owned my VR4 for 15 years now . Over this time I have built a forged engine. I stayed with the 2.0l capacity. All the supporting mod like improved fuel system , 3.5" stainless exhaust , Forced Performance FP3052 turbo , AMS sheet metal intake manifold .

Last year I decided to upgrade to a LINK G4+ pnp ecu but as I had just finished the HPA wiring harness course decided to make a custom harness from scratch with TXL wire and new fusing and relay box. I though while I was at it I would change the ignition system from a wasted spark system to a coil on plug direct fire system. I had to reconfigure the ecu to suit.

I did all the confirmation setup but decided to get a flex tune by a local performance shop .

The end result was a healthy 325awhp on 22psi on pump unleaded and 430awhp on 29psi on e85. I had a goal of 400hp so I decided to not push any harder for the moment as the driveline is mostly stock apart from heavy duty clutch.

My future plans are to fit my 2.3l stroker that I have stored with a better clutch and rebuilt gearbox .
