      Thanks for the info guys. Seems I have a lot to learn about these little beasts! Growing up in rural Wilkes Co. NC (the birth place of stock car racing) I never really understood the drift scene. As a kid racing go-karts and such it seemed the goal was always looking for traction and corner speed; the exact opposite of drifting
      I tore down one of the Miata motors today and noticed another difference between the B6-ZE and B5-ZE engines. The B5's pistons are pressed-on style and the B6's use circlips to hold the wrist pins in. The B6 also has an oil drain / vent tube in the back that you had pointed out earlier in this post. Which style is preferred, Pressed or floating?
      serious engine builders use full floating wrist pins. You will need bushed rods. Pistons can be machined for retaining clips or sourced from an engine that uses full floating pistons.

        My ZLde has the same block as that late B6d. Here is what it looks like inside the cavity that this hole goes into.

        It's just a cavity, made by the oil pump housing and the block.

        • The big end bore of the B6-ZE rod bore is also larger than the B5-ZE's. My El-Cheapo Harbor Freight gauge measures the B6 at 1.89" and the B5 at 1.69".

          • Yeah, carb dip is pretty amazing. Don't get it on your hands though, it's a pretty potent neurotoxin.
            The ZLde crank has smaller big end I.D. than the B6d too. I haven't mic'd them yet. They look like the same size bearings as the b3 though.

            • Read it in the first post, that you can run the b6ze with the stock b3 festiva ecu. But haven't been any to find any detailed information.

              Any links or DIY threads I might be over looking?

                I don't think anyone has posted a DIY or a real detailed thread on it. I'll be doing the swap shortly, I'll post up the specifics. I've never done it personally, but I've driven 2 cars with this setup and can say first hand that it works good.

                • Awesome, please any and all information on it would be appreciated. I already read your post about shaving part of the distributor, idle valve (which I don't need here in Florida) bypassed that on my first 1.6 miata.


                  Where are you located? If your in Florida I'd love to come hangout and work on some cool festivas?

                  • Joe & Charlie, would either of you be interested in the 1.5L rotating assembly as a partial trade towards a custom strut / shock combo? Thinking of using the 1.6L rotating assembly for ease of replacement parts.

                    • eh not really. I can do it but I've only put one of the "Advanced" setups together so I may not get everything right. I'd prefer to do a straight cash deal.

                        Possibly. I'd need pictures of the crank and rods first though.
