b16a2 w/ 12:8:1 compression question
ok, i have a b16a2 built from the ground up.I also milled the head to get me from 11:8:1 to a little less than 12:8:1. I have to run premium fuel, which is 90 octane here, and octane boosters. I know with high compression like that and me racing I will build up carbon on my valves right? other places? Any methods ANYONE has for keeping your internal engine clean (without having to take apart my engine all the time) and running good will be GREATLY apreciated. I really need help on this one! Also, is there any specific REALLY GOOD oil i shoud run with my motor? it only has 500 miles on it rebuilt. Plz help!

Yeah, seafoam is a great cleaning agent.
I don't know if it's meant for these applications, but Royal Purple oil is supposed to be very good, though extremely expensive ($6 or $7 a quart.)

I've used it personally but not on a high comp engine or anything.
on a B16A. I did it some time during the early summer of 05. Engine still runs fine. I didn't really notice anything though

Re: b16a2 w/ 12:8:1 compression question (JayDiemB16aCivic)
im using ngk iridium and im using the oil that is meant for my engine strait from honda. I just got done puting on a new thicker head gasket to add back on what i milled from the head and my ecu is being redone right now becuz with the thicker head gasket it advanced the timing. so my ecu is being reprogrammed as we speek.

Re: b16a2 w/ 12:8:1 compression question (94hatchvx)
Certain gas stations carry fuel that tends to have less carbon buildup (it was an article in a Super Street from last year). With that compression ratio the easiest way to clean it out is to run Cam2, Turbo Blue, or even race fuel. Even at almost 12 to 1 compression you should mix race fuel with the 90 octane so that your valves don't ping. I run a mix of Turbo Blue and 93 in my hatch on my street tune and straight racing gas on race tune. When I tore it apart to refresh it, my motor had no carbon buildup at all.
