13k for a turbo kit?!?!
Have you got a link to that? Must be gold plated or something
I dout very much it would cost 13k. A turbo would cost about 2k, allow 1.5k for custom manifolds and dump/font pipe. New injectors and fuel pump + remap. If you needed too you could lower the compression a little with a thicker head gasket. Even if you bought a second hand ford engine like your current one it still wouldn't add up to 13k.
You also have to think about getting it engineered. You can't put an old engine into a new car due to emissions laws. Getting a post 1997 RB25DET is going to be a bitch of a task not too mention expensive.
There is also the man hours involved in welding up new mounts for pretty much everything. If you can weld yourself then its not so much of an issue, but paying someone else your gonna get stung. Auto electrics are the same, you'll need the entire RB25 loom and the fairmont loom in the car at the same time... its gonna get messy
Still, if you wanna do it, I look forward to seeing the results
