They have a Mitsubishi TD06-17G. Some things to consider:
- Syclone/Typhoon (SyTy) engines have lower mechanical compression (8.35:1) eutectic pistons and nodular iron main bearing caps. Putting 14.7 PSI to a stock 4.3 will frag it in short order (several SyTy owners found this out when dealers replaced their engines with generic 4.3 short blocks).
- You need the ECU for a SyTy (or turbo sunbird) as well
- you can generally find parts for sale at
