WARNING...AUTOMOTIVE PORNOGRAPHY below. IF you are under 18 or of delicate disposition click away now!

Here is what the F1 style Barrel Throttle looks like in the Cosworth catalog.

And here is our used Barrel Throttle off the dead 2.3 Formula Atlantic motor all cleaned up and installed on our 2.5. Can you say throttle response?

Motor mounts are an issue. Factory mounts for this motor do you no good at all and attempting to work with them leaves the motor too high, too far forward, canted a funny angle, etc, etc. Thankfully, Tony at AWR is a custom motor mount pro and makes all our upgraded NC mounts. Tony's custom mounts dropped the motor down and back...but even all the way back as you see in the second photo above you can't use the stock alternator location. This alternator is a super small race unit from Cosworth and it still hits the steering. So, alternator will move to the bottom of the passenger side of the motor (better for our weight distribution anyway).

I wish I had more time to take pictures....I am sure I would like to look back later. But this is our busy season and the phones are ringing and ringing a lot more than last year. Today, I installed the brakes. Used our NC Big brake kit with two piece rotors and RX8 rear two piece....here are the product listings of what went in (will try and get shots on the car later).

While I was in the front brakes I got a better shot of Tony's engine mount. He made these for 2.3 install but they work the same for this 2.5 liter.

Brakes are in this morning (porterfield R4 pads, coilovers almost in (got a used set of Motons to try but I ordered the wrong rear swift spring diameter to go with them...). Lots of little things for Tony and I to finish up but 'hope' to have car to the dyno late next week...

Hey, Brian...I was told the Cosworth barrel throttle wouldn't fit without bodywork in the engine bay, yet your pics look like it works just fine. Whassup?

Hey, Brian - we were told the Cosworth barrel throttles wouldn't work without bodywork in the engine bay (making it an illegal mod for CSP)...whassup?? That looks like it fits just fine!

Can't speak to that...this 2.5 liter on custom motor mounts doesn't tell us anything about fitment on the factory 2.0. The other issue is that the factory 2.0 is drive by wire throttle and these are old school cable throttle. We have a Motec to run this one.

I understand the implications of what I'm asking but... would Motec be a viable standalone unit for street use MX5’s with more than usual modifications. What I mean is, the information interface between OEM gauges and the Motec unit may not be possible but I’m sure there’s a solution. What about advanced systems like ABS or traction control? Are those systems compatible or lost because of the change.

You would give up the dash, stereo wheel controls, cruise, ABS, etc. However, I suppose you could run the Motec as a parallel unit controlling just the engine.
