    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

        So the pump wires are on top?

        I ended up not getting to my shop this weekend. Any diagrams on r3v or in the bentley?

          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.

                                    E30 went to Arby's to get the meats. Actually got them from DrLeadFoot. Bonus motor pic with some updated wiring.

                                      Starter comes on and I've got fuel pressure. Properly hooking up the DME/EWS should get the rest going. Trial and error from here.

                                        Since I picked up those 17s, I figured I would post up the ACs on Craigslist. Unfortunately someone bit and they are gone...

                                        Still trying to figure this damn wiring out. I may bite the bullet and pick up a tuned DME that doesn't require EWS, but I would need a new engine harness and knock sensors.

                                        I'm justify it because of the additional HP.  :(
