well because i got a mint spec 2 at the moment and i need to have a engine built for my project so rather than rip out the internals of a spotless series 2 i might aswell buy the seriers 1 ive been offered with a knocking piston for £100
it will be ok using the spec 1 engine then. the only things different are turbo's, ecu's, ignition system and thats it. nothing internally i think is different apart from the camshifts maybe as tomei say the cams ( the ones they sell ) are diffferent between the two specs.
