Hey,
Check with Martin for the engine or even check with Ian at http://www.lostprojects.com
As for the install, I charge $1,000 for S13 swaps and $1200 for S14 swaps. For an extra $200, I also make intercooler piping if you need it. There are many options you can go with if you get your swap done at my shop. By this, I mean that the labor can vary depending on how much stuff you want installed. For example, an S14 swap, complete wiring, A/C working, motor detailed and powder coated, battery relocated, gauges mountedm turbo timer and boost controller installed, complete intercooler piping fabbed and powder coated, bearings replaced, etc....costs $1500 plus parts.
If you need more specific info, e-mail me at jwhitely2000@yahoo.com or call me at 813-546-3524.
