Same car with a forged motor and bigger blower? I guess a jedi or radical would be ultimate for speed but I couldnt go down the shops in one

I think when your car is prepped and rolling you won't want to part with it.
The 20g will lose 200rpm in spool maybe, but beyond that it will run more efficiently on boost than the 18g, so 1.5bar on a 20g will make more torque than the same on an 18g. I've only been in a couple of 20g cars and tbh the spool up didnt feel markedly different to the 16g. On a 2.5 its fab. Gerrys car will lug out of bends in 3rd where I'm faster going to second.
Got a VF35 in the cupboard but seems a shame to be forged up and not take advantage of the fact

All good points, I suppose what I was trying to say, is that there are a lot of different cars out there, I have had 4 Jap boxes now. Starting to think a slight change of tack is in order...I usually get a 2 year itch for a new car, and guess what, its nearly 2 years since I bought the RA :!:
Hmm, so if I were to get a 20g and run it hard, you reckon it would be a good turbo for my application??
VF35, I heard they aren't quite as good as the VF34's. don't take the boost so well or something.
