Torque is 135 @ 6200. I just uploaded another vid. 0-60 MPH 4.3 sec. and you get to see how it takes a tight turn and accelerates out of it. Next Mod. Just bolting in cams with undershim buckets and maybe 200WHP on pump gas. We are only using 10:5.1 CR with a slightly shaved head.

No plans for a Turbo for this motor. I wanted the fastest Miata that could be the fastest on a mountain course and a circuit track. I couldn't rev a Turbo to 9000 RPM. That's why we went ITB's for a light weight Miata. After NJ I will get on tracks that many Turbo Miata's have been on to compare times. ITB + Turbo will work good on a big HP circuit & possibly on a mid HP circuit.

Thanks! This past Sunday we took 1st in the Redline Time Attack Modified class at Nashville Superspeedway. Runnerup was a Viper & I was told by others that we were pulling away from a RSX on the long straight. Over 200 WHP Naturally Aspirated will be easy on race fuel and more agressive cams without higher comression pistons & stroker kit. Next event is RTA New Jersey at the end of August.

Is the head ported or no?

how is your idle set. are you having any problems or did you set your idle at 2k rpms?

[Erv187]

Do you know what your torque numbers are?

[ApexScalpel]

Looks and sounds great, I can't wait to see it in person!

[Saml01]

Now, you should throw a plenum on those ITB's and attach a turbo to that engine.
