Item 1 does apply to you, the newer bolts are the only style currently available, but you'd be better off getting some drilled bolts from Don Gale to safety wire them on. He has them for a very reasonable price for people.

2. Relays, I would get a main relay or dme whichever terminology you prefer and a fuel pump relay, I'd keep them in the glovebox after you fix the latch just in case they are needed. Fairly reasonably priced and decent insurance to have. Same reason i kept a GM ignition module in the glovebox on my trucks... plus as long as you have the spare, it guarantees that you won't break down... Its only if you don't have it that the car decides to break.

3. Fuel pump, Todds kit probably comes with a higher flow pump depending on how much boost you're actually going to run.. I gather you're going to use the low compression forged pistons and forged crank like the m30 turbo had


4. The latch is on the door itself, cheap from bma , fix it before it sticks and you really have to break stuff to get in.

5. You'll know it when the wheel bearings start to make noise, no reason to replace prior.

BMWE34.net "What Will Break" List

I have a 1990 BMW 535i 5-speed, 272k miles, currently undergoing extensive engine rebuild in prep for turbo build. What are some of the things I should look for?

1. Cam oil spray bar applies to me? Is it possible to order the wrong bolts or does BMW not make them anymore?
2. What relays should I be replacing? Fuel Pump, DME and LKM is what I'm guessing.
3. Should I be concerned about replacing the fuel pump? My turbo kit I think came with a bigger one that will replace the current one anyway... I'll check with TCD on that one.
4. My glove box is kinda catching on something when I try to open it... is the "latch" he talks about on the glove box or up in the dash?
5. Suspension is fresh and I don't get any noise or play from the wheel bearings, even after 272k miles... I think I can hold off on those as they have probably been replaced already.

Any other input... I'm mostly concerned about the electric system. There is a clicking coming from the steering column and I think it has to do with that steering nut thing, but I'm not sure. May have the dealership handle that one actually... I already have a new brake light switch... should I be concerned about the clutch switch one? There is also something up with the wire that connects to the rear driver's side turn signal. My guess is it is corroded or something... I'll check.

Thanks
