1987 Rx7 Turbo II - CHCA Hill Climb Car

warwickben · 12-01-2008, 05:12 PM

you guys are so lucky. id rather watch rally racing, hill climbs ect heck the baja 1000 (cant spell ) over drag racing and nascar any day. the closest thing to it near mass is scca rally cross events, which i plan to start doing.

i plan to build my sa up for rally cross and street use.

have you thought about intercooler setups. most fc hill climb cars i have see have a topmount/v mount setup. with a bigger scoop .

I have given most of my thoughts towards a v-mount for best cooling towards the radiator. I plan on running an NA 13B engine first though til i build (and have enough cash to get all the things that the turbo engine requires) so i get seat time.

I hear that lol

I got friends that live in Colorado Springs, if you go to the edge of their backyard there is a cliff and then you can see the air force school.

You should at least look into making it 4wd, I know it's been done before. Quite a while ago though, I don't have a link. If for no other reason because a 4wd '7, while still rotary powered, simply kicks ass.

but the money and costs involved, not only in building the car, but the increased costs of running ANY AWD car would be hard for me to handle.

warwickben · 12-03-2008, 05:48 AM

i here you on the cost of making a rx7 awd. id love to have one just to have some fun in the snow. there is not alot of info on the net about how its been done. what is out there is a custom tube front end and thats about it.

Whizbang · 12-03-2008, 08:58 AM

i know how i would do *most* of it. Maybe once i have a garage i might make one for giggles and shits rallycross use. Only thing would be steering and the hubs, but im sure i could find SOMETHING to do the job

warwickben · 12-03-2008, 04:05 PM

i have a picture of a carbed 2 rotor motor and drive train. its from one of the older rx7 rally cars.it looks like the front axel from a mazda truck, and drive shaft come out from the side of the tranny for the front axel.

id love to do it to my sa, heck it going to be off the road for a few years. i just dont know how to go about it.

AWD MPV drivetrain

Thats how they did it w/ the mazda factory rally FB...

Whizbang · 12-03-2008, 04:22 PM

the MPV had an R type trans?

warwickben · 12-03-2008, 04:44 PM

hmm? then you would just need the same diff gearing for the front and back.

bs?

WE3RX7 · 12-03-2008, 10:12 PM

Its not BS. Mazda had AWD MPVs they were able to use the drivetrain from in order to make a group B rally FB in the mid 80s. I'm not sure on the exact specifics of how it worked since it was a factory race car and they'll never publish the full build up. I believe Miller used 626 front axles on his AWD FB back in the day which are the same from the MPV so I don't see how it could be BS.

Its not that AWD RX7s are unheard of, its just rare and the people who have done it did it way before the internet so there is very little detail on it.

The MPV AWD FB is in the 1988 Mazda RX7 brochure.... its real, I promise.

WE3RX7 · 12-03-2008, 10:16 PM

Just checked. They mention the AWD FB in the 1988 brochure, but I believe the pics are in the '86 or '87 brochure.

The '88 Brochure shows Rob Miller's Pike's Peak AWD FC which I believe was also 20B powered....

Whizbang · 12-08-2008, 06:14 PM

that and the B2600 R transmission for 4x4 could be used.
