This is what I'm saying, but you CANNOT get 160bhp with a low budget. What this other guy posted about Shawspeed is for ppl with big budgets. I at the time didn't have a big budget, but still added everything that was available from Pumabuild and Burton Power.

Buty at the end of the day, the 1.6 block is weaker than the 1.8 and 2.0 Not matter who says it is, I've tried and tested near everything in the last 3 years. This was my conclusion.

And the Puma throttle body was good enough, much better than standard.
