I am working on an EP RX-3 that has what I believe is the original Nikki carb with primaries bored to match secondaries.

Accelerator pump shot was very weak. Diaphragm is fine, adjusted all for...

Thanks Mark and Bud! This is going to be a lot of fun.

I'll post official rules later this week. Meanwhile keep those ideas coming.

Bonus race is a go!

Australian pursuit format. Bonus race at the end of the day Saturday, open to SM and IT, standing start from the end of the grid, handicapped release time based on qualifying...

Thanks for all the input so far, keep it coming.

This is NOT A DONE DEAL but one idea we are pursuing is a IT/SM "Bonus Race" on Saturday at the end of the day.

We're still working out the...

A simple question, what can we do to make sure you attend our August 11-12 race?

I am looking for creative ideas to boost driver counts, particularly in SM and IT. We are looking at everything...

Oh yeah, it is possible, though a bit difficult, to replace both regulators without tearing the engine down (just drop the oil pan). While you're in there, add a baffle, $20, and if you can afford...

I assume we're talking about 1st gen RX-7's... ?

I’ll say...

I bought mine from Mazdatrix. Dual probe/dual needle gauge, reads to 1800 degrees, don't remember the price, but it seemed reasonable at the time. I don't know how accurate it is, but Dave Lemon...

Thank you all very much for the help! BrianB called it - I just got off the phone with Tokico and they're sending me a new set, no charge.

I have acquired a set of second-hand white Illumina 5-ways for my ITA RX-7 and the number caps for the rear dampers are missing

Can someone please tell me how the numbers relate to the flat spot...

You're right, of course... I didn't phrase my question well - what I want to hear is how someone can justify the gears as legal for IT. I can't see any loophole there.

Steven

Thanks for all the replies! I am convinced that the "hardened 3-window rear stationary gear, hardened front gear" are not legal, but I think that everything else is okay.

If I did go with their...

I'm engine shopping. Here's how the Mazdatrix website describes their "ITA Special" engine:
