I have read that fitting other heads and camshafts off differant engines, raises the compression and makes it quicker is this true?
I have got the top end in pieces so any tips on wot to do before i put it back together mucha appreciated I really don't know much about engines so please help.
I have got a 1.2SPi engine out of a corsa i can take bits off, and i can get hold of bits off a 1.4SR nova engine.
So wot do ya reckon?
Its goin in a MK3 astra.
