Otherwise, I hope you're converting to a manual at the same time in order to make use of the power you're looking for.

Really, with all the aggravation... just sell the SPI-powered car and get a Zetec-powered car. If I was that concerned over making serious power in a Focus, that's what I'd do.

On a different performance note, you could track down a SPI header (Focus Central shorty header was the lesser of tow evils IIRC), a high-flow cat, MBRP / Magnaflow cat-back exhaust for the tail end. Dump in the most raucous cam escortfocus.com has - don't forget the springs, lifters, etc! Find a used BDR / FC 60mm throttle body, add a 3" intake (short ram or cold air), move to 8 or 9mm wires (Screamin' Demon coil / LiveWires package) and top it off with a SCT tune for 91 or 94 octane, adjusted shift points, raised redline, etc.

Don't forget the 50% UDP.

From there, you can do suspension / wheels and tires, perhaps a brake upgrade, etc.

In any event, you could likely end up doing a lot of what I've mentioned to your Zetec-powered car. It's just a matter of "how fast do you want to go?" and "how much are you willing to spend?"

Good luck either way. :)

Id go the zetec swap route before doing that....i honestly cant see that much performance coming form those bolt ones and tune...then again, my diea of power is different than yours.

Try Lecavalier reckers in Cumberland, ON, I picked up my spare zetec motor for cheap, but it was just a motor....no ecu, no alternator, no starter....etc. Latst time I was there they had a engine with about 80k on it, they were asking $500 with 6 month warranty.
