On a mild K20a with K-Pro, headers, CAI, valve springs, cams, and cam gears, is 13.5.1 pistons to much to be used as a daily driver? Or better, is this to much compression for a 90% stock block and head?

 

are you going to retard the timings like crazy? if you are, then i dont even think its worth going that high. if you're not, make sure u can get high octane gas.

on the topic of it being a daily driver, i would have to say no. can you honestly afford octanes higher than 91? 91 octane is almost 3 dollars a gallon down here in so cal. its hanging around this price and i dont see prices dropping drastically anytime soon. so, if you're going to do some sort of 50% 100 octane and 50% of 91, it might cost u around 4 dollars a gallon. if cost goes up, so does your gas, so you might want to think twice about going so high. also, you have to hope you never ever get bad gas

 

Thanks, that is exactly what I was looking for.

 

I wouldn't go over 12.0

Stock compression is fine, its already 11.5

 

I think that 12.5:1 would be max comp ratio for a daily driver!

stock is 11:1. the highest honda/acura has for their production cars in the US is 11:1. they had this on their k series and the f20/22. i think the TL also has 11:1. not sure about other honda/acura cars.

 

can you keep up with the gas prices is more the question in my opinion

 

if you run 93 octane, and have k pro you whould be fine with that comp ratio, if you have a good tuner

but it whouldnt do you any good, you whouldnt make any more power with that comp ratio, over say 12.5:1, theres no reason to go that high with stock head, stock cams, stock im, and stock block, there whould be no real gains from it
