The springs are stock.
Do you take your car out on the track? Cause at first it was all nice and firm, but after a few outings and the occasional twisty road run it started to go all soft.
It's easier if you sell it off and get a car that's turbo from factory cause insurance companies will consider the car as "modified". You need engineer's certificate, upgrade brakes to match the power and maybe other things. It's a headache you can do without. Talk to the guys at the cruise and they'll tell you the same thing and maybe even more.
it's more than just a bolt on cause, now it's too much of a high compression and the ECU will not take too likely to a turbocharger being wacked on.
Sorry to say but transplant is the best way to go.
Mr R32 is here!
It sounds like a transplant as R32 came in RB/20DET/25DE/26DETT.
Taking the turbo will make you slower than R32's with a RB25, cause like others have said, compression is too low, and may play funny games with the ECU.
That stat doesn't really tell the story cause it doesn't take into account how many times the pace car came out to slow them down, or it it was raining like hell. But still is a good stat to have next to the GTR's name.
Leave elvis alone! I can understand if you pay out on bee gee's but elvis lives! Village people, start doing the YMCA and guarenteed to have the copper running away.
