We have been racing a 200 20v the last few years on the west coast in Chumpcar and now luckyDog racing. We had the engine go at the end of the year 2015 so now I'm in the rebuild and upgrade process. Anyone familiar with chump car racing knows about the build rules and we had stayed within those. Now we are going to race "EC" class and luckydog which is more open for building. I'm hoping that everyone can help guide me in purchasing the right parts and making a pretty killer car, I'm an experienced mechanic and actually own a car dealership, but I could really use some insights.
The car is currently a pretty stock drivetrain 91 200 20v. We gutted the car, had RaceTech build a custom cage and painted it simular to the Audi DTM early V8 cars. The mods that we currently have are 17z front calipers with C230 sport rotors, no bracket, just used a grinder and some brass sleeves, works amazing on this car. The rear brakes are stock. Engine mods are a Ben Swan chipped ecu with spring, that's it! The seat is a composite RaceTech with dual locking sliders since we have a wide range of drivers for the 24 hour races. We are also using the stock cluster but it went haywire last year. Added some switch panel items in the lower center console. The dash is stock but covered in Alcantara! looks cool. We also have a fire safe fire system. Front windshield is stock, rear is lexan, we've been racing with the door frames out and the crash bars off, it makes the doors insanely lite weight, but I think that I'll add the rear door frames in again and switch the glass to lexan with a driver vent.
What I'm going to try and do is make this first post a place to keep track of brainstorming ideas people might have for certain areas of the car, then I'll update them as we make the upgrades so that people can see what we end up with. Hopefully it will convince someone to do the same thing and come race with us! Any ideas or advice is greatly appreciated, forgive me if I come up with ideas that are just plain Stupid...
Needed Car Upgrades
- Body
The hood is very heavy, possibly build a carbon fiber or fiberglass hood, possibly even all the body panels:
Other ideas???
- Fix----
- Chassis/Suspension
- Fix---
I've also looked at the DIY write ups on the suspension but I'm not sure if it would be much cheaper, or more reliable??
- Brakes
Need to add a bias valve though.
Need to change to wheel studs instead of bolts, bolts are the worst during a pitstop, I saw a conversion kit somewhere.
- Wheels/Tires
We run a 180 tread rating tire, so we have a few different sets that we like, that's pretty easy.
We need to find one more set of lightweight wheels, perferebly 9 or 10" wide, we run 255's right now.
- Engine
- Fix---
Block: Try and get by with what we have, it's a 200K mile stock short block
Exhaust: Upgrade the manifold, 3" downpipe, right now it's a stock down pipe with 3" exhaust out the back now muffler. Maybe do a side pipe out the b pillar passanger side.
Turbo: Thinking Garret BB possibly GT 3071 or GT30r not sure.
Wastegate: maybe Tial drop in
Ignition: Deffinetly coilovers or ls2 coils
Intake: one of the cool redisigned jobs for the 3b??
ECU: Deffinelty VEMS I think, V3 harness start from scratch
update 1/28/16 Ordered the Vems V3 and the Twin shield harness
Update 1/29/16 Canceled order with vems.hu, reorder through Marc at EFI Express
Intercooler: Not sure, craigslist special, custom piping with v bands?? Really like v bands for race repairs, makes it much easier
- Gearbox/Clutch
- Fix---
- Fuel System
- Fix---
- Interior/Driver

Need to ditch the factory cluster, it's to hacked up. I've been looking at the AIM system , even the GT Wheel http://www.aim-sportline.com/eng/products-car/gt-steering-wheel/index.htm or the MXL dash. Also the Dash2Pro https://www.race-technology.com/gb/racing/products/display-products/dash2-pro. Both work with the vems inputs, the wheel would be pretty trick.
- Setup
- Fix---
- Aero

::We have races coming up soon so I'm in high speed mode, any ideas are greatly appreciated, no mater how crazy, I even dream about running a compound diesel style dual turbo system, maybe next year. I'll choose what we do by the concensus of whoever chimes in.
Thanks in advance... I'll include lots of pictures and videos
