    Continuing on with my MO of spending just a few minutes a day on the project, I finally got the intake manifold off.

    It isnt called a "mess under the intake" for no reason!

    OBD1 will only slightly help with that.

    For those that arent aware of the difference between an M50 manifold (thick and healthy) and an M52 manifold (frail and anemic), here it is

    After I remove the E39 harness, brackets, and accessories I will be plenty busy cleaning the block.

    RealOEM will become invaluable as I make a list of other clips/brackets/hoses that I didnt buy yet to mount the OBD1 harness and accessories.

                    All you have to do is bolt a supercharger on to win the race (this comment works two ways)

                    I would be very interested to see how this M52 would do against an S50 though

                              Injectors are back from Injector-Rehab

                              Turnaround time was great and they returned the old filters and parts as proof that they replaced them. I gave them a fresh coat of paint to finish them off.

                                  I think it was $106 after all was said and done.

                                  I first checked into new injectors but enough knockoff Chinese "Bosch pink tops" exist online that I decided it would be best to just rebuild a set of known good ones

                                    I have found refurbished genuine Bosch injectors on Ebay to be the way to go.  Paid 65$ for the flow matched set of ev6 injectors recently.  

                                    Information a little too late, sorry.

                                      I was mainly drawn to choosing my own refurbisher since I could get a printout of the test/some sort of evidence to show that they are flowing evenly. It wouldnt surprise me if you had some folks just blasting some brake cleaner through them :P

                                        That is quite possible, although the reviews were good and I think they were cheap because the application was very obscure, Ford SVT 2.5 from 99-00 only so probably trying to get rid of them.  He claimed to do all kinds of stuff, backflush, ultrasonic, etc flow test within 2%.  I have no way of knowing if any of it was true though.

                                          My goal for today is to pull the block and trans from the car and say my final goodbyes to the m20

                                          938628d3767125d7ac38da5061986112.jpg

                                          I have decided to shift my focus away from the M52 refresh for a bit because next up is swapping out the M52 cams for some S52 cams, but as I look into the steps involved it looks really easy to screw it up so i need to do a lot of reading before i dive in.

                                          Once the M20 is pulled i will do some scrubbing, repainting, install the E21 booster, and cut the mounting brackets off that i made for my intercooler.

                                          Im still shooting for the end of august, but I will definitely have to replenish the car fund somehow to buy my last round of parts that I need and pay for some welding
