I have the stock seats and they are in pretty good shape.

Parts left to finish swap

Ecu
Wiring Harness
Clutch
Sensors
Alternator
Water pump
Power steering pump
Belts
Custom drive shaft
Custom Exhaust
Custom Intake

I would do after market aluminum heads they drop the weight of the engine by around 90lbs and add a good amount of hp.

I think the swap could be completed including the heads for around $2500 if you only use new parts. If you use the stock heads and buy new clutch and junk yard the rest of the parts you could finish it for around $1000.
