I have read a lot of conflicting information concerning the strength and engine management issues when boosting Honda’s D series engines. So, with that said I hope we can dispell some of what I've seen.


Boost Pressure on a stock bottom end - I’ve seen numbers ranging from 5psi up to 12psi. I’ve noticed on the kits that different manufacturer’s sell start at 6 to 7psi, but the owner’s of these kits seem to turn up the boost. I’d like to be near the limit of the motor (50k easy miles), but still have a good margin of safety. I’ll definitely be running an intercooler, which should also help.

Engine Management (read: fuel delivery) – What is the best setup to deal with the boost and keep the cost down? I’d love for Santa to leave an AEM ECM, RC injectors, and a new fuel pump under my tree, but lets face it, I haven’t been that good this year.:naughty: So, what other options do I have, and what are the benefits/drawbacks of each? I want to do it right without spending large sums of money.

Thanks,
Andrew
