'91 Formula 3rd gen project - F-Body Road Racing and Autocross Forums

Found this 120kmi 305tpi/5spd car May 2005 in the San Francisco Bay area:

Set up a web page for it here:

'91 Formula WS6

Some of you here know about the project, probably most don't so here are some details. When I picked the car up it did not run well, surged and ran rich. Got that all handled, needed new injectors, radiator and a bunch of stuff under the hood. The 305 dynoed at about 200hp at that point, car competely stock. Since that time I had a March "street car" underdrive and 1.6rr put on it, that perked it up some rpms. Also had the front end rebuilt with a Spohn kit to get rid of the drunk 3rd gen sway! (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif) Put on the mandatory Global West Del-Alum bushings. I had some SLP 1-5/8 headers for it and small pile of goodies, some suspension pieces from Jason, some Konis from Sam, and Blaine Fab plans for an exhaust and subframes. Found a great deal on barely used Edelbrock TPI base and runners (from a forum member here), and staying 305 was the way to go..until... (IMG:http://www.frrax.com/rrforum/style_emoticons/default/gr_eek2.gif) a 383 stroker was found in the CMC forum! Turns out this L98 stroker actually ran CMC in an '89 Firebird in the early early days when they were just trying to get bodies! Needless to say this CMCer was kicked out pretty quickly after the class got going and did not put many miles on the motor.

So, 383 and T-56 and Superram it is! I am hoping to do some autox (for fun) with this car if they ever get any venues back in my area. It has pretty much been eliminated with out an hour or more drive since 9-11. Also an occasional lap at Thunderhill. I want the car to stay stock looking, even using the stock wheels. Ed Miller over at TGO has an interesting Wilwood set-up for the front brakes which should fit.

I replaced the stock rear which interestingly enough had an aluminum drum rear. Due to some production issues GM "ran out" of the '91 4 wheel discs which normally come with the WS6 option. I found a '90s disc rear for it, THEN I decided to put a 383 in it! (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rotf.gif)

Since then I made a couple decisions - decided LS1 brakes are fine for a mostly street app., going with an EB Miller kit and what is left from my LS1 brake set-up from my 4th gen CMC car. Late braking (ha!) news, I was able to obtain my old 3rd gen CMC car's rear end, a nice GM parts Dana 44 with a Detroit Locker. Hasn't been touched since I last raced it! A hearty thank you to my past and present CMC cars for their contributions! Can't wait to drive this sucker! I'm gonna see how long I can lay down rubber marks on my neighbor's driveway (don't worry, we around here consider that a right of passage. Pretty kewl 'hood!).
