Go with the VF34 and STi injectors. Keep the top mount. Add the Walbro. Switch to NGK copper plugs (BKR7ES-11). Switch to a better engine management system than 4 HKS piggybacks.

The VF34 with injectors is capable of 240 whp on the stock IC, which is more than most stage I SRTs make. Unless you run switchable maps for race gas, a new intercooler won't be a huge difference until you are well over 400 crank horsepower. And even then, I would recommend sticking to a top mount.

But... I thought FMIC is the way to go for all out HP. The other down-side to FMIC, is longer pipe runs... Hmm.

It is, as long as you define "all out HP" as north of 500 or so.


Pogi, I would not recommend the F-Con. Modern software technology allows reflashes and piggybacks to make all the available power from your bolt-ons without inducing any drivability or tuning issues. There's nothing a stand-alone or single-function piggyback (like SFCs and boost controllers) can do better than the factory ecu when it comes to idle, emissions, throttle transitions, etc. while the EcuTek reflashes and Xede can do all of the horsepower tricks of the old types of engine management. To top it off, one reflash or Xede costs less than an SFC, EBC, timing controller, and J&S Safeguard.
