Performance gains

2001 Prelude; What is the easiest way to gain about 20-30 horse power without getting to carried away. Like I don't want to change cam-shafts or pull off the cylinder head. Does doing any intake mods throw any codes. Does a header really gain that much power, other than ripping off the stock muffler and installing a straight flow unit. On my '86 prelude I installed a turbo muffler and put on a bigger exhaust pipe mid way and gained big time power. Probably 15 horse.

You'll be stressed to pull off any real gains like that without dumping a little bit of money.


Changing the intake won't throw any codes
Changing the intake manifold to a Euro-R won't throw any codes
Changing the intake manifold to a Skunk2 will give some issues while obd2
A good header will net some power, but it should be also tuned.
Motor mount upgrades are a great way to pickup on some already existing power.


For just bolt ons and a tune, you could certainly get a gain but there is really no saying exactly what combination to go with and how well they will respond based on your elevation/region and motor health. Expect to spend upwards of 2k in parts prior to the tune, though.

Thanks for the info - would you comment on this more? I'm new to this platform but a big fan of mount upgrades/inserts and prefer something that doesn't add too much NVH but still makes a noticeable difference. What brand do you recommend and could you post a link of where they are available for purchase?

Thanks very much in advance.

No, you didn't. Bolt on components make very little difference in Honda systems, because Honda tunes them very well from the factory. If you want those kinds of numbers, you must go into the engine.
