    Jesse brings a good point

    Jesse has a good point about valve clearance on my car. For those of you who don't know I did 10:1 Miata pistons in my dx with my milled ported and polished head. I have no idea what the clearence is and my engine builder doesn't remember. All he said was that it was close. I don't know. Should I consider swaping over to a dohc head now? If so, what all is involved and should I pull the motor and do the manual trans conversion at the same time. How much time and money should this take if I do it all myself? Thanks guys.

    I take it your cars an auto.
    Well you put all that time and effort in milling the head, you might as well use it. How does it run?
    I would just recomend switching the car over to a 5speed.

      I runs good over all. It idols rough and eratically (sp) but she goes. I had a guy at work hook me up with a S-AFC along with my Venom 400. I think that could be a problem. It seems like you have to opposites trying to fight the fuel map. I don't know. He doesn't think it's a problem.

        Venom 400 won't do crap on a Protege ECU. As soon as it clicks over to closed loop, the Venom can't do anything. It only works at partial throttle.

          I see, so should I run the afc only, or keep the 400 for just off idle. I guess the it was an expensive mistake.

            AFC shouldn't work either...same reason. Closed loop defeats it.

              so there is nothing I can do to both monitor and control the a/f ratio electronically?

                  I don't know man. That seems a little intense for a sohc. Maybe I can justify it though. I'm building another BP01 with regular Miata pistons and am going to attempt a turbo. I have a lead on a guy in a town near mine who will build that manifold I've been talking about. I think I'll have to learn tranny's fast and get my slopbox auto out. Screw Level 10. 3400 bucks is a lot of money for an auto trans. Although... you can shift like a manual, only loose 9% from the flywheel, bullitproof, and can tranny brake...

                    I doubt that you lose only 9% from the flywheel.

                      I'm a little doubtfull too, but that's what they're pitching.

                        on average you lose 17.3% from the flywheel.
                        When you turn your car on... does it return the favor?

                          Yeah, that's how I understand it too. They say that with there transmission due to the clutch packs, valves, and electronics you will loose even less power than any manual transmission out there. That is what made me so interested.

                            the power lossed is due to FRICTION.... be it a lack of(clutch) or excess of. now if they have found a way to get rid of friction i would LOVE to hear it. there are people doing doctorates on the subject, but billy-hick and his slack jaw buddy have figured it out. no offence but tread carfully, remember the phrase if it sounds to good it probably is.

                            And there is only power loss during clutch slip, if you clutch has locked the how are you losing power through it...? the 17% is from a running engine, as in the clutch and flywheel are locked.

                              The other advantage of an automatic tranny is the time it takes to shift. We are starting to build one where i work for my protege. I had a manual tranny this summer and made my fastest run at 13.6 with the gtx engine all stock at 10psi. For next year we have started to work on a garret t4 set-up for the engine. It's pretty shure that we are going to break the tranny sometime but hey that's in the game of going fast, has long has i don't break the engine i'm going to be glad.
