im tellin you man, its not worth the trouble. why go for a car that is inferiorly engineered compared to the mk3 with the SAME problems, guaranteed.
they have a shitty steering system, the transmission isnt strong, youre boned when it comes to the fuel system and engine management unless you go stand alone. the motor sucks because its a SOHC. the only DOHC cam head was made by HKS and a repro run fell thru about 6 years ago. the brakes suck on these cars, the interior pretty much sucks, as does the body sheet metal. also, swapping in a 4G63 is not easy. you need either an Aussie tranny or a dodge D50 tranny which isnt strong anyways. the bolt pattern on the bell housings are NOT the same between the G54B and the 4G6x motors.
yes, they look cool and thats about the only thing they have going for them. when it comes to being a sports car, they suck.
IMO, the best way to do a car like this is to either build the motor, top to bottom. that includes removing the steam jets in the head to prevent future overheating/head warping. then, buy an Aussie multiport efi system. after that, run either megasquirt or SDS EFI. rebuild the ENTIRE steering system since its a drag-link system, not a rack and pinion.
for the same $ amount invested, the MK3 blows away the star-quest's. dont get me wrong, i dont hate them... i just dont think sensible people should own them.
