I started modifying my car a few weeks ago for autocross. It's a 1973 1.7l car with a more or less stock 1975 2.0l engine, very clean. After the Portland PCA AX #1, I made a few postings and got some suggestions. Rather than continue to hijack that thread, I thought I would start my own.
So here's where we are at today: Tarrett Engineering front sway bar installed and set to mid point 225# Rear Springs and perches Koni Sport Adjustable Shocks set 1/2 turn from full stiffness Turbo Tie Rods 205/50-15 Kuhmo Ecsta XS Tires Empi 44mm Dual Carbs (replaced a single Weber) Mallory Unilite Mechanical Advance Distributor JWest RennShift side-shift Triad Headers and Exhaust System - heat disconnected of course Porterfield R4-S Brake Pads - to be installed next week I think that's about it. Damn, she drives nice. Super tight in the corners. Wow. So, what's next? Besides just drive and compete. I know that. I don't plan to miss a single autocross opportunity in the Portland area. Pictures next. Don't complain yet. Would love to get more ideas and suggestions. Thank you, Steve |

There is a long slippery slope just ahead.....you may not wanna get too close to the edge. (IMG:style_emoticons/default/biggrin.gif) |

There is a long slippery slope just ahead.....you may not wanna get too close to the edge. (IMG:style_emoticons/default/biggrin.gif) JP is right. Bontempi (High Performance House) will tell you the same thing: it takes a year of autoxing (and simultaneous instruction) and schools, if they are available, to get on the right path. Given the power that you'll have and the tire setup it's easy to get find yourself on that slippery slope - having to fight handing issues instead of concentrating on learning how to drive. Actually JP isn't kidding about that slippery slope. When you put that 2.3 in you'll have jumped on to the slope head first, especially with 205 tires. To be honest I wonder if the 205 tires would work in any event, even with an LSD. Remember that Jake's motors pump out a ton of torque....mine is over 190ft lbs at 5000 RPM, which would just shred 205's. One bit of advice pertains to your base setup. I'm sure there is someone up there that knows how to get a good baseline - this will make a huge difference. I like Rich Walton down here...every time he has base lined one of our cars it simply worked afterwards. He is going to be getting mine when the cage is complete and I get my little 4 cylinder back in. |
