Yep 300KW is my goal, but the secret is achieving that without banging on a big turbo and just screwing up the boost, a big turbo will make power but it will be far too laggy. It would not be a good street or track car. Ok for your just drag racing from a standing start.

Its a fine balance to get the right setup. I'm in the final tuning phase so I'll know in about 2 weeks what my setup will achieve.

The Walbro fuel pump is easy enough to buy locally. What you really will have to get is an aftermarket ECU like a link or megasquirt. This will allow you to really get the best out of the engine. To hit 300kw at the wheels you will have to be pushing up to a minimum of around 21 PSI of boost.

Yeah so this is whats going in next (sometime in the next month or two) and a few other things i cant remember off the top of my head right now
I want to run about 20psi but ill leave that up to the tuner to keep an eye on air/fuel ratios etc to keep things safe.

Next upgrade

Big turbo (HRC 35rs)
