4age tuning cheap tips????

[firehawk]

We raced a full season of endurance saloon with our AE82 FX-GT running a fairly stock smallport 4A-GE with fully balanced lower end, Toda 3.7kg flywheel, TRD 0.7mm head gasket and 0.2mm shaved off the deck. The power increase probably wasn't very spectacular but the added compression and lighter+balanced rotating assembly made the engine really pleasing to drive and it revved like motorcycle! Although we were able to outbrake them by almost 20 meters, we got really badly beaten by the BMW E30 325i:s with their big engines and big power that kick out some major straightline speed.

After throwing in a pair of 304/8.5mm cams and a TRD group-A ECU, the engine got really peaky and didn't really pull until 6500rpm and went up to 9000rpm. Since the endurance saloon regulations forbid re-gearing transmissions and limit the final gear to those which were only available on that bodystyle, the car was actually about a second per lap slower due to slower corner exits. Went like crazy on the straightaways, though. The lesson is: going for more power on a small displacement engine isn't always a good solution.
