Stock engine run fine at the track. Change all the fluids, brake, tranny, diff. Maybe track pads. I smoked my stock pad first track day. K&N air filter.

change the oil banjo bolts out to OEM ones for the F22. Add Ti valve springs/retainers/keepers (or upgrade to the F22 version if you're on a budget) to protect your motor from valve float at higher RPMs. Get a baffled oil pan.

refresh all fluids with quality replacements. check the crimp on all of your brake lines (replace with SS-lines is better). Get some decent track pads (DTC70/60, XP10/8, Project Mu CR).

Leave motor at stock power levels. Take the car to the track.

If you're not brand new to the track - I'd suggest doing all of the above anyway and modding after you've really driven the car.

If you plan to track the car seriously for a lot longer. Seem weld the front control arm pick up points - they're spot welded on early AP1s and have been known to tear under extended hard cornering conditions (especially on sticky tires).

FYI the oil banjo bolts changed mid year in 02 so you have to check your serial number, you may already have them.

At stock power levels I would say baffled pan, ap2 retainers and keepers. Banjo bolts down the road, or if you up the power levels.

TI retainers is a bad idea, just stick to AP2 ones.

Also, pretty sure Europe has a recall on the banjo bolts that America didnt get, so see if that was done already.

Baffle is always good for piece of mind especially on sticky tires.

If it's a track car, and you're not taking points for it (if you're compeeting). The Ti will save your motor from a 3->2 10K RPM money zing shift (yes, I suck, errors are made, but i've done this early on in the tracking life of my car - it's still going 40+ events later.). YMMV for a street application car (although mine also doubles as a street application use vehicle and has 95K on it).

After that, just change oil, keep up with your spark plugs, and valve adjustments - shorter intervals for you tracking applications.

OP, how much track day experience do you actually have? If you are a novice or an intermediate driver, don't waste your money trying to upgrade your engine. You already have more power than you can manage!

Seat time alone, will make you and your car faster. Even when you think you have reached the limit of the car, you haven't.

Spend your money on track time and safety.

But these are the things you should consider: To get the car running right: Valve adjustment; AP2 valve retainers; Billman's timing chain tensioner (I believe he will ship to England); new fluids all around, including brake fluid. To upgrade for safety and reliability: braded brake lines; competition brake pads; oil catch can for an AP-1; decent tires; front A-Arm reinforcement welds; roll bar, harness and race seats; HANS device.
