I just changed the oil and tuned the Hilux 22r (carby and petrol), well to the best of my ability) .
I have a few questions you might be able to answer for me.
1)The manual recommends 5 degrees but I have advanced the timing to 8. It even ran at 10 to 12 without pinging using premium fuel. I'd like to know if it will be ok to keep it at 8?
2)I have acquired a set of Lukey extractors 4 into 2 into 1. With a 2 inches diameter at the end. I plan on putting an exhaust on it this week. I have been quoted at $430 including gasket and fitting of my extractors for a 2 1\2 inch full system. Is it worth it? What should I look for or ask? Any better ideas at getting a bit more go without too much money.
