I broke the cardinal rule - I did not take pictures of the engine harness as I disassembled. Now that I'm putting the engine back together, I can't figure out the routing such that the IAC and the TPS can be reached. Does anyone have pictures of the harness routing between the manifold...

I'm planning on using Koni Yellows, of some varient, in a new build. A common option is a tubular strut housing that can take either Bilstein or Koni inserts (8610 or 8611). I could also go the route of a Koni 8742 (essentially an 82 series Koni with purpose built attachment flanges). I see...

So I'm pulling together parts for an ITS RX7, and both T1 and T2 Torsen's can be found for an NA FC. Which is better for our car? My understanding is that the T2 has less lockup during decel, but is that true? Has anyone actually tried both?

When discussing rear spoilers / rear wings, ITCS section 8b says that " Dealer installed or limited production front/rear spoilers/air dams/wings are prohibited" I failed to find the term "limited production" in the glossary. For example, the Miata 'type R' was, in relative terms, limited...

Is the exhaust diffuser in the exhaust port considered an 'emissions device' that can be removed? I know we can't port, but can this device be removed - and if so, what sort of impact does it tend to make on the performance if left in? My understanding is that it is VERY hard metal. Thanks for...

As my family is rapidly growing, I'm finding the need to be more creative about raising funds to go racing. I'm entertaining the thought of renting out my ITA car for drivers' school, maybe for a race or two to qualify a racer. I've never done it before, so thought I'd ask - what sort of...

Does anyone have a contact or information in regards to practicing on Friday? Do you need to have had an annual on the car before you can practice, or just a license? I've got to do some shake down laps before this weekend.

I've got an '83 fuel tank has either a pickup restriction, or is sucking both fuel and air; I disconnected the hose right at the tank and put it in a can, and the pump draws just fine from the can - it barely dribbles when drawing from the fuel tank, with 10+ gallons in the tank. Is there a...

I'm going to try Summit for the first time on June 18th, provided my new engine runs by then. Anyone from NER planning on heading south? Any suggestions for a first timer at Summit? ------------------ Dave Youngren NER ITA RX7 #61

I want to put an O2 sensor in my 1st gen header, but I am worried about the high exhaust temperatures. How far downstream does Mazda mount the stock O2 sensor, and has anyone with a 2nd gen had difficulty with getting O2 sensors to last due to excessive heat? ------------------ Dave Youngren...

Does anybody have a trick to installing the oil pump sprocket without pushing the stupid key out of the pump shaft? I unfortunately found mine under the engine stand...after installing the front cover. It took me many tries before the key would stay. Also, what's the easiest way to tell that it...

I have been racing with the same tranny for 4 years, never needing a rebuild. At the same time, I've been running with a stock clutch and pressure plate. I just picked up a 4 puck, and started to wonder - is an undamped/abrupt clutch the reason transmissions fail on RX7s? Should I still use the...

Well, it looks like I'm staying in New Jersey, but (shhhh) I really enjoy NER - how do I switch from NNJR to NER? BTW - anybody have a working 12A for less than the cost of a rebuild kit (and center plate, and end plate, and ...) : ) ------------------ Dave Youngren NER ITA RX7 #61

Anyone ever rebuild a 12A with the gasket/seal kits from Victoria British? Prices look to good to be true... [This message has been edited by dyoungre (edited September 11, 2003).]
