As Ken said, that car is pretty clean as it sits, the more you molest it, the less value it has. If you want to molest something for the power, get a cheap 86+, do an LH2.2 +T, and save us the heartache of watching this prime 242 Turbo go from BaT-worthy to California crusher-bait.
This simply isn't true. Kjet is for someone who wants to drive a stock car as it came from the factory. This is turbobricks, not brickboard. Very few people know how to add value properly to a 240(it can be done and it won't be easy or cheap). If op wants reliability, he will need to ditch Kjet for fuel injection. There isn't a way around that.
