      Ehh.. I don't like V6's that much, although the Acura one is one of the best.

      Hmm.. I just had a thought. 4AGE blacktop... wonder if I could make that work ;D

      Ideally I'd like something characterful, high revving, reliable, light, and under 200ft*lbs of torque so I can use first gear. Also can be mated to the stock transaxle.

        Ive had so many ideas of what I would want to swap in one... I think the best move is a VW motor and make it fast just to really stick it to the Porsche snobs that it is NOT a Porsche...

        NARP is a real thing lol

          4A-GE Blacktop would be awesome! Have always loved the sounds and characteristics of those.

            Did you ever get the MAF working?

              Not exactly. I think I did update a while back where I got it to power on through a voltage supply, so my next idea was that the pin that was loose (happened to be the voltage pin) was probably getting pushed in so that it did not contact. I was going to fix that in place somehow, then play dumb and follow the instructions to see if it works out.

              I also bought a new enclosure for it since the 3D printed one disintegrated on me.

              I haven't really tried anything on it since last update honestly. My starter is going out for some reason now, so I pulled it out yesterday and will be putting a new Bosch reman in it later today.

              I figured after that I might try fiddling with the MAF a bit more.

              How about you? You had a MCK too right?

                I got an MCK as well- I haven't made any progress, though. Hopefully once things settle down a bit I'll get it installed.

                      Thanks! For the most part, yeah. I plan on finishing the MAF conversion, doing an oil cooler, mtech1 spoiler, and euro valence + fogs.
                      I'm taking it at my own pace because the car is awesome as is, pretty much everything I could've hoped for and even then some. It's not perfect, but its close, and will only get closer as time goes on.

                        So I wanted to share something quite interesting...

                        I was having a few issues with my car, first being that I had these bad hesitations that seemed to happen more and more often. I checked almost every piece of my ignition system and kept thinking I fixed it only for it to come back again. Meanwhile, I had gotten a gauge for my WB O2 sensor and have been monitoring it to see how good my tune is under various conditions. I noticed that WOT was super super rich at 9.1 AFR which was also causing a more subtle hesitation when at WOT. The other hesitation seemed ignition related as it was a more sudden lurch than when running rich. Also at part throttle my AFR oscillated around 14.7 even though I would still get hesitations.

                        On a whim I tried plugging in a totally stock ECU.

                        Not only did it fix my hesitations (so far, at least, 3 days strong) but my AFR at WOT now hovers around 11.8-12, which is nearly spot on, maybe a few tenths too rich.

                        So, I guess somehow.. S52 injections= richer, M30 AFM = leaner, displacement/cam/comp = leaner... So somehow the stock tune works well? I have no idea to be honest. But my car has just been an absolute joy with the stock tune, it's running more solid than ever! Hopefully it stays that way :). My old ECU must have been wonky at least, but I'm more surprised how seemingly perfect the stock chip is.

                          Any plan for a exhaust video? I'd love to hear what this combo sounds like.

                                I will try and accommodate. My car is relatively quiet. Sounds a bit hot rod at idle, but you wouldn't notice anything is different unless you're an E30 guy ;)

                                I love the sounds at WOT, definitely makes it feel like an event, that's when you really can tell something has been done to it hehe
