We have scheduled a Double Regional + 90-min. closed wheel enduro on Sun. + PDX. Gauging interest in enduro on Sun. afternoon after 2 days of racing in hot Aug. Memphis heat - assuming you are going, would you do the enduro? It's only an extra $80 w/ both Regionals. Also, would you be...

For the umpteenth time, the front muffler on my SpeedSource single 3" system either busted or, this time, broke off. I was going to replace it w/ the ISC front section and weld on the rest of mine (that is still good) but Mike is out them and not building anymore soon enough. What good exhaust...

Steve E., help! For those of you out there w/ SpeedSource cars, have you had to replace your window net yet? I don't see how to do it - the lower bar has 2 90 degree angles and I don't think the net will slide over them; the upper bar has the latch welded right in the center. I have to have a...

We're finalizing the schedule for our big double National/IT Tour 3-day weekend and I have a question for the IT group. Would you prefer to run both races on Sun. (that's 3 sessions total) and be done or have the second race Sun. a.m.?

Over the years no matter what I do it always seems that I get some leakage out of the shifter mechanism. Runs down the tunnel and looks like crap. Anyone have a permanent solution? :shrug:

I have someone who may want to rent my ITS RX-7 for the Double School here at Memphis 3/14-15. I will not be driving those 2 days and he can't stick around for the Regional Sun. so, logistically, it works well. I'd prep the car as I would for myself and I have a used set of Hoosiers he could use...

OK, first off let me confirm this: I am assuming that all 2nd Gen. 5-lug axles are interchangeable - right? Specifically, I am trying to install a '91 axle into an '87 chassis (and also assume an early diff.). What's the friggin trick to get the diff. end of the axle to line up w/ the...

What is/are the best book(s) on suspension setup and handling info that translates best to underpowered sedans like ours? It's about time I learned how to make my car handle.

I went up to Louisville this weekend to meet Chris Ludwig to dyno-tune the engine he just rebuilt for me. We were on a Mustang. Before I reveal the results, I thought I recalled a discussion of how to compare Mustang and Dynojet rwhp, but I can't find it. In the range we are talking about for a...

March 10-11 w/ test day on 3/9. Memphis BBQ and St. Louis beer party Sat.! :birra: IT gets 2 races w/ separate sanctions - count as 2. Go to Memphis Forms- fill 'em out and mail 'em in. :eclipsee_steering:

W/ Christmas coming up there will be plenty of sales on home air compressors and I may be tempted to ask Santa for one. How much capacity, hp, and pressure do you need to operate basic air tools and/or a paint gun? Yea, I know I should only get one the size of the "Little Boy" A-bomb but I have...

We've exhausted ourselves over on the Mazda forum so I'm throwing this out here. I don't think it is really a Mazda-specific issue. 2nd gen. ITS RX-7, new battery + 300 amp booster, new rebuilt starter, new plug wires, 2 events on engine rebuild This car has always turned over slowly but now...

Ever since I got this ex-SpeedSource car it has been somewhat difficult to crank. I hear other cars crank right up like a street car but this one doesn't. Now I can't get it to start. :bash_1_: I have changed the starter, charged the battery, and have it on a battery booster pushing 22+ volts...

Has anyone ever had a situation where the thing just won't time right? I just had my 2nd rebuild of the season and can't get it running right. I set the crank at 5ATDC, align the CAS marks, and insert the CAS so that the screw is about in the middle, where it usually is. When I put a timing...

Is it just me or does everyone have problems w/ blowouts? I tow w/ a '95 Tahoe and have had different tire brands but the result is always the same - they never just pick up a nail and go flat - they have catastophic tread separation while pulling my car down the highway at 75. Just had one Sun...

I have to replace the hose and inlet/collector on one side. I'm not sure what's stock and what's not but the inlet/collector piece that the hose attaches to is approx. 3" x 6" w/ angled 2 1/2" hose outlet. Frankly, it looks like a vacuum cleaner attachment. Does anyone know if this is a part...

Set of 4 new, in box, G-Stop Goodridge braided brake lines for 2nd gen. from Mazdaspeed. Includes front fittings and rear banjos. $100 shipped.

I traded out my Pi system for a set of analog gauges and got an old used Mallory tach in exchange. I wanted an in-dash and it would be cool if it worked because it is 3+" and has a shift light and rev limiter. Try to find that at Autometer. However, I am now convinced that the thing is reading...

Side seals went a month ago; both rears were in pieces. I got the engine rebuilt and have it back in and have just gotten it to start. It seems like it will run OK at higher RPM but, of course, I don't want to run it there yet. It is extremely rough below 3000-3500 and will not idle. On the...

I know this has been discussed before but not in awhile and the top RX-7s seem to be going faster and faster. Am I correct that there are 3 choices: stock iron, carbon (Racing Beat), and ceramic? The first 2 are priced about the same and I am not seeing why the carbons would be any better...
