Thanks for the input Smiley, given your back ground people should listen and learn from what you have to say as there is no compromise for experience.
Guys - if any one wants a performance engine built to a above average spec then touch base with Smiley fron DATSQIK HARDCORE JAP ENGINES, for he has been playing with Turbo charged engines before half of you were even born. Please don't bother him with basic questions , simply touch base if you want the best build and he will advise as to whether it's interesting enough for him - Yep - one of those guys, knows his shit rather than talk it!
