Send me your engine and a shit load of cash and I will build it for you.
Seriously though, for the VE engines there are a few things that you can do.
Get the crank from a Almera GTi and a set of SR20DE Eagle rods and put them into your engine.
Stick with the stock SR16VE pistons and you will net 2 litres and approx. 14:1 comp. ratio.
You will need to dial out a few degrees in the ignition timing and use at least 98 octane fuel.
Get yourself some N1 camshafts and an N1 intake & throttle body.
Match it to a good filter such as the BMC Carbon unit and use a good cold air feed.
The removal of the fog light or fog light blank is ideal for this.
Get yourself a Hotshot Gen. 6 header if you can or a 20V header and then match it to a 3" exhaust system with no silencers or CAT's and only a rear can.
Get a fidanza flywheel and an ACT HDSS clutch.
Get some lightweight crank & water pump pullies.
Get your ECU reprogrammed so that you can rev to 9000 rpm.
This will net you around 250 HP if tuned correctly!
Cheers
Dave
