Well so far I have gathered the following:
hks steel internal new turbos. direct replacement for standrad items,
r&b decat pipe, hks exhaust, hks blow off valves.
I dont mind getting the parts as I have a few contacts in the trade and also there is some good deals to be had in the second hand market etc.

I also have a brand new gt35/40r turbo with hks external wastegate, is it not worth going single turbo conversion with this??

As for forged pistons etc Cam are not selling a set?
If I go to that extent I my as well replace oil pump etc
thanx for the info guys
