Pls anyone share some ideas with me..just wondering is there any differences between R34 GTR vspec 2 turbine and GTR vspec 1? some said the vspec2 is slightly bigger than vspec1..is it correct?
my question is,the 4g15 with siemens ECU can be matched with high cam?i think it does need a piggyback to fine tune the fuel.so does this kind of mod possible?need ur expert advice.
