If I keep the engine, I can just rebuild it. Here'* the simplified and less costly alternative for the upgrade:
1. Rebuild the engine with supercharger engine internals (ported and polished heads, etc).
2. Ported MAF opening.
3. Replace the headers with Ceramic Ported Headers.
4. Rebuild the 4T60E tranny or get the 4T60-HD tranny.
5. Replace the exhaust system.
6. Maybe bet a custom chip.
I think that'* the most I can do without replacing the drivetrain. I'd like to know the make, part numbers and pricing for the exhaust system. What'* a good performance hiflow catalytic converter and muffler? Does anyone have a good system with the split before the muffler (similar to the new SSEi and Caddy Seville STS)?
