Ohh well, the D16Z6 is a Vtec engine, USDM spec
It is a D-series engine, cant say it's an odd motor, if you want to go for a car wit a Vtec engine, tthis is an option too. You can interchange most parts from other D-serieses, like you can use the header, filter and even the transmission from your car on this motor afaik. Fuel consumption won't be abnormal, as it has been chipped. And 150BHP is a bit far fetched I think, not sure, incase it had internal mods. Anyway, like anyother car you can look for common probs rather than worrying about this motor
So why didn't you look up the engine code on the block?
