I'm using skyline RB20det
Ongtekweng, I'm not pro lah, just been driving and modding for one year plus only, but a lot of things had gone through within this one year time, so most of the problems of this engine i will know, the most kacau problem of RB20 is only the AFM, need to service every 7000km or so....so I'll be planning to upgrade to stand alone ECU using MAP sensor, no more AFM to kacau me...haha
if wanna use original skyline rims, must change to 5 lugs already, must invest some money to do the conversion also, but the benefit is u get more choices of rims from branded companies from japan loh...it depends on your budget lah, can get original R34 rims 18" for a very cheap price, 'cause most of the owners of R34 will change rims once they got the new car, they'll sell their ori rims cheap cheap one (without the tires of course)
