the sil80 was a 400 car run some are legit..most are smashed 180s as s13 fronts were cheaper more common.. but in all honesty mate for what you want to do a N/A r33 wont cut it.. 32 yes or S chassis you'll never look back.
sure 33 is better interior etc but very heavy without a turbo you'lls truglle to get sideways and do a good job of it you'd basically have to leave stockies on anything with more rubber you want go anywhere
the mercer im driving atm is horrible. handles like a boat, throttle responce is terrible. i have to really put my foot down to make it move, < i imagine an N/A 33 would be sameee
gtst hows the sale goin man? ur car is clean as
