    Which one of these do I need to tap into for the fuel pump?

    I assume is the fuel pump and one transfers fuel from one side of the tank to the other?

      I think there's three lines off the tank. Fuel send/return and the third is a breather line that runs up to a charcoal canister and then to a purge valve to the intake. The connector on the furthest left of the pic looks pretty similar to the coolant level sensor, I'd imagine it's gas level (?) the middle connector is probably for the fuel pump. Don't quote me, just guessing

        Yeah it's 3 connectors but I'd have to go look at the e30 Tomorrow.

          So the pump wires are on top?

            Down pipes and gutted cats are in. I need to way to trick the secondary O2 sensors so I don't have a CE light on all the time. I am thinking I can tap into the primary and run a resistor or buy those O2 spacers that trick them into thinking the cats are there and working.

            Mach up - Thought it looked pretty cool.

            Waiting on my C101 and then I can start the wiring. Still need to tweak and reinforce the remote booster and run all the plumbing.

              What DNA radiator are you running? Looks to be thicker than an e30/e36 one

                  It is supposed to be for an E30. I wish it was wider, but I will wait to see what my coolant temps are and change if needed.

                  Haven't looked any further into the wiring. I got as much done on the exhaust as I can until my hangers show up. Pretty happy with everything thus far.

                    Just make the o2 spacers with spark plug antifoulers. I know plenty of people that have made them with great success and for about $4.

                      Do M62s use the secondary O2s for air/fuel or just to see if the cats are working?

                          If it is a TUB engine, they are used for air/fuel I believe. The early models do not use them for anything other than cat monitoring, as Snap said.

                                TU = totally useless.

                                just set the cams to 'hot' and leave them alone BMW, this isn't risotto.

                                  A lot of my exhaust was just tacked up so I finished as much as I could before running out of argon yesterday. Started the wiring and just picked up some more argon to hopefully finish the full exhaust this weekend.

                                  Bad news is I seem to have a rear main seal leak or a transmission seal leak.

                                    Mine was leak free for about 2 weeks. Came out to the garage and I saw a tiny drop under the car.

                                      Pulled an all nighter Friday and got the motor harness all hooked up and some more work on the exhaust.

                                      I have most of the wires identified and know where they need to go and think I have the EWS figured out as well.

                                      Probably 10 hours from firing, but still have a lot of driveability stuff to do (finish brakes, clutch line, cooling, etc)

                                          How about open downpipes?

                                          I want to make sure my 02s are in the system for tuning purposes.

                                          That being said the exhaust I have is all 'see through' muffling. It definitely wont be quiet.
