I head swap

[e30trooper]

So should I return the harness? And get an older one? Or cut the square plug and rewire another one?

lol, looks like you need to read some more dude. You need and adapter to run a late model harness. Bmw used the round c101 from 86 and up. You can buy one or make one.

The 85 Eta doesn't even HAVE the round plug that the 90 harness has. You need to make an adapter.

You should also buy some rebuilt 19# injectors from me to go withthe head swap.

19lb injectors are too big, he should run 17lb M50 injectors.

besides connecting it to the fuse box and bridging wires for the OBC what would be different?

ive read strictlyeta's guide over and over hoping i can get this whole thing done in a day. lol.

as for injectors, i have 6 that i took from the junkyard. just gotta clean em out.

Your harness is NOT plug and play. GL bro..

[bcusitsjeff]

he did do a vaccum check and that tested out fine. and he did do a light surface cut.
but other than that he told me the head looks fine. so hopefully all really is well.

if worst comes to worst and something happens to the motor ill probably just junk the motor and put in a m50 or something. lol.

I've yet to see a used head that didn't have some warp. So I always have a light surfacing cut (~0.005") done. And I'll break down the head, have the valves ground, and install new seals. The shop I use has a cam profiler so the cam gets check for wear and buleprinted or replaced.

[bcusitsjeff]

the guy at the machine shop said it was fine. soo hopefully everything goes smooth. thanks for your concern though...

[MR 325]

I hope the head you're installing has been pressure tested and resurfaced as well.

[bcusitsjeff]

damn i didnt get that when i picked up the stuff today

[jlevie]

would i need to swap the distributor also?

No, but you will need I ignition wires.

[bcusitsjeff]

would i need to swap the distributor also?
