Track ti build (M52)

[spidertri]

I've worked my way up the HPDE ladder and I'm at a point where I'd like to take the car into time trials or possibly racing. Either of those would require more power to be competitive.

I'd seriously looked into an M44 ITB but costs were fairly prohibitive and there were no guarantees on the gains.

Anyway, M52 swap is tried and true, I am looking for reliability and reliable power on track.

Last month I picked up the motor (M52b28), wiring harness, DME, manifolds, PS pump, alternator, gauge cluster, airbox, battery cables, and FPR from a 328 part-out. I plan to refresh the motor with new gaskets and seals, clean it up, and simplify as much as I can before swapping it in.

Plans for the motor:
- Beisan vanos seals
- IJ crank scraper
- Valve cover gaskets
- Oil filter housing gasket and freeze plug fix
- New timing chain tensioner spring
- Rear main seal
- Achilles motorsport oil pump shaft upgrade
- Achilles motorsport reinforced oil pick-up tube
- Check/rebuild the oil pump
- Gripforce stage 2 chromoly flywheel
- A/C delete
- Water pressure sender
- Oil temp sender
- Euro expansion tank
- Z3 S54 radiator
- Aluminum tstat housing
- MMW Swap tune

and probably more, the snowballing has taken effect.

To get the car running I'm just planning on using the stock 328 midpipe and adapting it to a Z3 3.0i catback section. Eventually I am going to build a high flow, 2.5" single pipe out the back.

I'll try to update the thread as I make progress.
