Boosting is not the only reason to chip an ECU... An all motor setup could definately make use of a higher redline...

But I agree, on this engine, and with the mods in mind, it would be a waste to chip...

Honestly, I dont even think this engine in particular is worth any modding... With the moeny spent you could swap it out for something else, at the very least a D16A6... But with the A6 you have MPFI, and it responds very well to modifications...


As for exhaust size, you need to have a game plan... For instance, do you want to boost? A boosted (forced induction such as turbo or super charger) would be better off with a larger exhaust... All motor on the other hand while it likes to breathe, it cannot be too big or itll hurt you...

My best advice, is sit down, write down what exactly you plan to do with this car... Drag race, track race, daily driver, daily driver with some spirit and go from there... Then once you have a game plan get online and find out what setup is best for what you plan to do... And go from there... Hondas are great because there are SOOO many different things you can do to them to suit your needs... But first you need to find out what those needs are before you begin modding...
