My late and lamented 1988 Civic street car:
Here is an example of a budget project:
Stage 1: Track ready street car
buy Civic DX - 1200$
change bushings - 500$
buy used Koni shocks and H&R springs - 500$
pads-discs - 150$
Stage 2: ITB legal, but slow
weight reduction: 0$
roll cage: 1500$
used seat: 200$
kill switch, etc.
Stage 3: ITB, closer to mid pack
Si final drive: 200$
generic header: 120$
race exhaust: 200$
Ground Control coilovers: 400$
I can't stop thinking about a project like this! Damn the SCCA for making my dream of a 100 hp enduro-friendly Civic race car more realistic!
I think if my short/medium term plans were to stay in Canada, I would probably sell my SiR and buy a tow vehicle, trailer, and start this build.
The worst part of a plan like this is that it starts with a 1200$ car... so easy... must resist...
