After selling a lot of the OEM parts I have just under $3k in it.
Long Block $450
Built TH350 $400
Trans adapter kit (used) $250
Evo 8 turbo and manifold (used) $300
FMIC and IC piping $250
1G AWD 5 speed ECU $45
SAFC2 $125
B&M ratchet shifter w/cable $125
Head rebuild $125
Torque converter $150
Drive shaft adapter $85
Timing components $200
The rest is gaskets, hose, wiring, gauges and lots of little things that really add up. I found a lot of deals on these things over the past year through ebay and craigs list. You could easily spend 10K or up depending on how fast you want to go with it. I'm probably going to switch to DSMLink or an Evo 8 Ecu next year. I had the LM-1 wideband and the water meth injection in the car all ready so I didn't include that in my cost. The irreversible part of the swap is having to distort the front of the trans tunnel for clearance. Not driving the car for a year was a pretty hefty cost too.
