lol, yes the motors are cheap, everything else associated is not.
my mate has one in a series 4 RX7, goes good when its going, but if the wind blows the wrong way something breaks, fart with too much weight on the left buttcheek something breaks...
christ, ants stopped the fucker.... got into the coilpack made a nice home and totally destroyed any spark generating capacity... new price? near on $1000... afm (i think) died, new price? theres that 1K again.
so yes, a good conversion but only if you have good hook ups on cheap holden parts. and thats not too hard, a lot of the parts are easily obtainable 2nd hand, but who wants to keep putting 2nd hand parts in their good car?
oh and as much as you can claim its a buick, its really a holden, holden into ford is just plain wrong.
