Anyone have any thoughts on which motor I should use? My 1995 has 200k on it and I am thinking about using a 1999 or 2001 motor for the swap. Naturally aspirated now, may go turbo later. Thanks for info!

Are you replacing the engine based on age, failure, or due to a bad oil analysis report?

The last two are acceptable, while the first is not

Well low compression, oil blow-by and most seals are leaking...it really needs a complete rebuild. I thought my money would be better spent on a newer motor with a little better air flow and solid lifters.

'01 will pretty much necessitate the use of a standalone ECU with VVT control but it is a better motor. If you're going to stick with a more traditional MS setup and you don't have plans to build the motor, do a '99 block.

Thanks for the info. What would be the advantage of using the 2001 motor? Does it give up any torque down low with the VVT? I really like your car Savington! What rear wing are you running and what spring rates and ride highets are you running? Thanks!

VVT gives torque low and power up top. It's just a superior motor.

Savington's setup: Raceland coilovers as low as they'll go. Slammed hellaflush.
