Macpherson strut is the best thing since sliced bread.
lol @ tryna find a set of camber arms for double wishbone setup
Anyway, just get an SR S13, fuck putting an RB in it unless you're doing all the labour work yourself, and pick up the engine for nothing. RB20's are pretty shit, I'd gladly have an SR over an 20. 25's are nice, but for the amount of fucking around and work involved, unless you just lurve RB's, stick with an SR.
CA's are kinda cool in that 'cute' way.
At the end of the day make your car lighter by stripping aboslutely everything non-essential out of it, get a locker or 2 way, get some small rims, and it shall negate the lack of power a bit, you should be on your way

, oh yeah and make sure your hand brake works
oh yeah, find the happy medium between a clutch that can take a beating and one that isn't stornch enough it breaks your gearbox
on a side note I can't believe there are only 2 QR drift sessions a month??!!??!!!?! fkn hell, it's like I gotta learn everything again each time I go out there cos I forget it /exaggeration but you get the point
Oh yeah, if there is adivce i could give you, it would be to buy someone elses project, fuck spending 3 times the money on something you would be lucky to sell for a third for one day. There are plenty of good setup cars being sold off on secret drift ranging from $6k-$15k
