Mr RB20
I am also interested in the same mods..... i ve herd that the VG30 turbo is a excelent and cheap upgrage for the RB20. but dont expect more than 190-200Kw @wheels. however rebuilding the VG30 (with a steel exhaust wheel) plus hi flow can get a little laggy, and will probly only make 200 -220 Kw @wheels... exactly how laggy i dont know ive spoken 2 a few performance places and know one can give me a straight answer.... does any one have any other info???
