But, people already create 4-door '87 GTIs. That to me, seems even worse than using a 94 (1.8) Miata tub for what will be raced as a 91 (1.6) car

According to solomiata.com, which is typically pretty reliable...
94-3/95 had 8.8:1 compresion ratio (though advertised as 9:1) and OBDI
4/95-97 had true 9:1 (due to taller dome on pistons) and...

SCCA Solo requires the R package trim on R package cars in Stock class, which leads me to believe the trim was factory installed.

If it were a dealer option, it would not be allowed in SCCA Solo...

I use the MSD Blasters. I was told to use the off-road version, but I forget the reason.

Looking at the MARRS results, where both classes are well represented, both have similar levels of competitiveness. The top tier cars are pretty close, the middle isn't too far back, and the last...

I use the solid center, 4 puck Racing Beat on my 1st gen. 2 seasons, no problems, looks almost new.

Thanks for the help guys.

1. Charcoal canister (evaporative emmissions bit). One line from the can leads to the oil fill tube (crankcase). The other leads to...

I'm converting my Spec RX-7 to ITA and have a few questions. The carb is currently a new stock rebuild, I plan to leave it that way for now with the exception of removing the emmissions stuff.

No CX specific header that I know of, but the block is another derivative of the ubiquitous D-series, so DX headers might fit. It is a different head, so I'm not sure about that.

Also, I believe SRFs rent for close to $2000 for full weekend.

I'm not sure how profitable renting alone would be - many shops rent cars as a means to generate future business.

I used to crew for Rotary Performance in VA. If I recall correctly they rented their Spec RX-7s for $600-$700 for a comp school weekend. They were good cars for a while, but eventually were pretty...

Depends on the quality of car and level of trackside support.

With full support and delivery and a top-notch car, $800-$1000 is not unreasonable for a full weekend or comp school.

It can be done - I drove my Spec RX-7 on the street for the 1st year I raced (though not daily).

But, it might be easier to buy an old pickup (I'm thinking mid-90s Ford F150 base model) and a tow...

I'll second the tranny mount. Or the driveshaft/u-joints.

Stock 12a rotary puts ~90hp to the ground.
SRX7 12a rotary puts ~105hp to the ground.
ITA 12a rotary puts ~125hp to the ground.

I do not know what a stock 13b puts out, but most SpeedSource cars...

In DC, the following is allowed:
K&N (in stock housing)
Coils, plugs, wires are free
Timing is free
Stock exhaust manifold
Remove pre-cats
Replace main cat with hi-flow
Cat back is free

The Spec RX-7s in DC are making 105rwhp w/ stock exhaust manifold, no carb work, stock intake filter housing, and full emmissions gear.

That is dynoed with <2psi fuel and timed somewhere near 24*.

My understanding is, as long as you use the correct counter-weight, it will work (and I have seen some cars do this). But, as it is illegal, I have not attempted to do so myself.

Most of the difference is intake manifold and ECU tuning. Also, in the last few years of the 2nd gen, there was an increase in compression ratio.

I've seen GSL-SE in C-Street Prepared (SoloII)...

Title - not requiredto race, but nice to have for resale and street use (since you want to develop as you drive).

Then it's gonna cost you an awful lot of money to build a car from scratch.

Buy something prebuilt, buy a dolly ($500-$1000), and have fun.

I built my own car, spent about $6500. Could have...

Joe - yeah, we want to build it. That's half the fun.

Well, as I mentioned in another thread, my roommate bought a 1974 Mercury Capri. He talked me into co-owning it and assisting with the build-up. It's got the Pinto 2L, so will be an ITB car here in...

Adding an MSD box would be ok as long as the spark still passes through the dist cap on it's way to the plugs.

The method jrx13 mentioned (using extra coils that fire directly to the plugs) would...

jrx13 - would this be legal?

The ITCS states "Any ignition system that utilizies the original distributor for spark timing and distribution is permitted"

I would think the dizzy would need to...
