hey, im lookin for a skyline r32 gtst 4 door, but i want to get an engine conversion to a rb25 non turbo, as new p plate laws dont allow us to drive turbo. im really keen on the 4 door skyline, but cant afford a r34 and dont like the r33. how much will it cost me if anyone knows to get the engine coversion from the rb20t to rb25 non turbs, and is ther anythin else i would hav to do or consider in this change, will the car run ok? will the turbo stock parts have to be changed?? please help!
