THANK YOU for posting the dyno! Love seeing that flat torque curve. It looks beautiful, how has it been for you?

Can you tell me a bit about that intake manifold? What throttle body is that and how big is it? How about the Exhaust? How does it sound? What did you have to do to convert to E85?

Any plans for the future?

Thanks!
Its been really good to us, quite reliable. I designed and built the intake manifold, not going to give away too many secrets on it but I do build them for customers. Throttle body is stock for the LE5, no mod's to it. Header is a modified FBR header for a polaris and 3" exhaust front to back, has a really deep exhaust note.. For E85 we just put bigger injectors in it from Flowforce and we run Fuelab pumps/regulators so the rest of the system was prepped previous to the engine install.
We will be adding some custom cams and valve train upgrades eventually but for now its doing quite well. I'll post those up when the time comes. I do have a build thread if you wish to read a bit more. https://www.miataturbo.net/build-thr...4-build-99336/
