but to the OP, you have lots of options when modding the IS. NAT, 1J and 2J swaps even V8 swaps. all depends on what your interst is and your budget

here you can see the madness of the Skyline IAC system. its retarded - has a separate regular IAC and a coldstart solenoid however both feed into the same hole. the solenoid must be plumbed into the chargepipe and not open air because they are known to leak boost.... i hate nissan.



c's shifter with TRD ****. i also got a shifter extension to raise it up about 2" from stock. shifts at this height are nice and easy and my hand doesn't have to move as far down for shifts. "shortened" shifters FTL!



i still love the look of the weld cover every time i look at it =)
