PA Hillclimb

Are foreign spec parts allowed for any classes outside of specials and modified? I'm curious about a couple options.

can i ask why?

im just going to go ahead with the LSD diff then.

From experience, which is a better setup? The limited slip or having just an open diff. I ask because i am at the point where i need to figure out which differential i want to run. Diff 1 Vented Disc Brakes Limited Slip About 70lbs heavier than Diff 2 Diff 2 Larger Drums Open Diff. I know open diffs...

thanks!

It states they they are the same for Stock except the list of disallowed tires is different, but it doesnt list anything. so i checked stock rules and it says i have to use OE tires??? but i can use any wheel diameter and tires size in the CSP....

Joe, can you check to see what the ITA verdict is for using a GSLSE rear axle assembly?

i hit a stock carb jackpot so im switching to ITA

great news!

You may have a problem with your brake mods and rear diff... What year is the GSL you're taking the rear from? Is it a non-turbo car? If it is not listed with the other RX7s shown under "Street Prepared Class C", the swap is not legal; further, allowable brake mods are ONLY those listed u...

So here begins a 1982 Mazda Rx7 GS project. Bought the car locally for $800 from a local guy. Has 70k on it, very well maintained (had the factory window sticker). Only missing the carburetors he had on it (they were a rare, dual Weber 36 setup). So this should be a great starting point. My goal is ...

so i think i may have final figured out some of the rules on classes.

I think i want to go with the C Street Prepared class for the 1982 GS. I can use the 12a engine without porting modifications, but use an header and from what i can tell an different carburator setup.

okay so. i printed off the entire SM and SP rules, plus the IT and Production rules. Now i shall read.

for ITA, it states under 9.1.3.D.5 "All single carbureted cars may fit and approved optional carburetor. Approved carburetors are: 1 Weber 32 DGV/DGAV/DGEV 1 Weber 32 / 36 DGV/DGAV/DGEV 1 Weber 32 /36 DFV/DFAV/DFEV 1Weber 34 DAT/DATR/DATRA/DMTR 1 Holley - Weber 5200" The thing is all of th...

another question:

are level 1 or 2 production categories allowed?

i picked up the 1982 GS model last night. Real clean shape. I plan on doing as stated. CSP. im actually rummaging through the GCR pdf from hell for 1) exactly was CSP stands for and 2) the rules! As for the Street Mod class, this is actually the first i've heard about this. What rulebook PDF would i...

well being that i don't HAVE the engine for the GSLSE. So that IS going to be a problem unless that car is going to be a "special". Frankly, i have no qualms about running in a class where i have no chance in hell of winning as long as i have some fun. So lets then look at my other car. 1...

it would be VERY hard to tell the difference between the 84-85 13b and a 86-88 13b because the only differences is the change from 3mm to 2mm seals, compression and i believe that to be about it for the actual block. Everything else is a bolt on change over. Plus if the transmissions had to come fro...

so i may almost HAVE to run the GSLSE in "special". but i do have a 12a powered 1982 that i could possibly run in another (cheaper) class. Both arent expensive builds really.

so the spec 7 might be good for the 82. or IT
