Is 12,000 miles a fair estimate? Or am I underating stock internals on a K series motor?

K's are built like tanks, that's why they're so popular, new technology and better design.

if i'm correct, you are definitely underestimating the k's internal's. I'm not sure what trim, but i've seen a mid-500hp boosted setup on stock internals at over 2 bar, and it could handle that, but it's not recommended for a dd, or reliability with that setup.

i know im gonna get some laughs for this one but its for a friend and he's not trying to do much right now....

1.5L SOHC

upgraded fuel injectors
boost controller
no intercooler (for now)

how much boost will be safe on this engine? 6-8 psi?

the head doesn't fail on boosted honda engines, the bottom ends do -- especially piston rods, piston heads and block walls/sleeves...

No laughs from here my freind. I <3 1.5L's.

Read the FAQ sticky of this section. You'll find "psi" or "lbs" doesn't mean squat.

Try a DSM T25, get an intercooler, and use a Z6 head/IM//ECU/etc. Check out a HF/CX/STD manfiold on homemadeturbo.com also. Keep fuel (premium) around 12:1 and run conservative iginition timing. It should be good for ~200hp.

ok just to make sure i understand you all. if your want to take a stock n/a motor and boost it and still have it as a dd, for relability and safety, it is good to lower the cr. so after you have a complete turbo kit, plans for a good tune, what would be the easiest way to lower your cr and how much lower would it have to go. i don't know alot on this subject just trying to fully understand every aspect of boosting before i even turn the first nut to do it.

they're concave therefore they increase the volume of the combustion chamber at TDC therefore they reduce compression kinda thing.
