Sard Fuel Press Reg- dont use one
Sard 550cc Injectors-Ive got 800cc gives me room in the future
HKS 3037 Turbo (or Garrett equivalent)- I went bigger (T04) which is a bit laggy but punches like Mike Tyson, the standard one high flowed is good though.
Top mount turbo manifold ???- Like mine but looks out there if you get pulled over and cops pop the hood.
Front facing Intake plenum ???- I got a Greedy knock off which is preforming well and much cheaper
Electronic boost controller ???-Profec B 2
I use a LINK ECU to control the thing
It all depends what you want the car to do, drags, circuit, daily or something of a all rounder which will be good at most things you throw at it.
Work out what you want your car for, then you can work out how much power is needed(over about 280kw needs forged internals if you want it to last) and what you need to get there and what is just wasting your money, but first do your brakes, quality tyres and suspension which is the most important factor of the build up.
