I don't really know...but I would start by buying the ECU, wiring harnesses for that Model. Also, You should try to find if it has the same block at the 98, cause if so your tranny should bolt up nicely. This is a pretty cool project, keep us posted.
Finally got my engine! 1996 teksid bock, cobra crank, manley H-Beam, diamond pistons, 4V b-heads.
Next Steps: Ported 03 cobra heads, Stage 2 blower cams, some form of 15-18 lbs boost---Gonna be a Beast!!!
