Boys you know I can't talk business on here I'll be joining chip lol!

Mat, have a look at r5ford t38 in the for sale section
Its one of our spec ball bearing turbos and is cheap, could be worth buying and selling your bits on, his made 450

You could use standard head and cams and piss 400 but it wouldn't be revvy, a inlet cam and a slight clean up of the ports would be so much sweeter mate and see 439-450 at sensible boost levels
