my engine block has compresion of 12.2 is ok if i put a turbo kit in it?? is it safe?
coz my friend said that its not....

 

my cummins runs 19:1 compression and 45 psi..... so i'd say you can run a turbo on that compression. Lots of tuning, lots of fuel, low boost, high octane...

its also i diesel......if ur running a 12.2:1 u would have to run 100 octane all the time do u even know how to acheive that high of compression or does the person that said that even know?

i think he means 9:1 compression ratio, anything over 10:1 for honda motors would be retarted to boost, example the k20, 11.5:1, i haven't seen anyone boost it, and if they have, i garuntee thats some low boost, under 8psi, your already on high compression

high compressions + boost = good bye motor.

look up cheesefrog's hatch on youtube and theres a video of him getting a tune/dyno run in thats a stock k20. dont tell people bad info(saying this nicely) anyone can turbo a higher compression motor the tune is where not blowing the motor up comes from

and no he doesnt mean 9:1 compression ratio. the compression ratio of a diesel motor is a lot higher than ours BTW

 

will a stage 3 crower cams fit my engine coz i changed its pistons thankyou guys

 

high lift cams with high compression pistons should be 'clayed' for clearance.
also its possible the valve reliefs are not big enough or in the wrong place.

 

sounds like you need to do a lot of research, instead of asking all of the questions in one thread. the z6 cam will fit in a d15b, but from what im told the d15b's camshaft is slightly more aggresive, so swapping them would be pointless.

i have a d15b and im actually running a z6 shaft cuz i fukced my d15b's up a little last time it was out, untill i can get my crower cam in my head this weekend

Yeah, that would be the main problem area.

I mean yeah, you'll be shooting stupid high compression numbers for a daily driver, and will probably need to run 100 octane fuel every day (which is perfect for ya if you consider the way gas prices are ) - though that's not even the real beef. The main problem comes into effect as wmac said, with a longer lift duration of a more aggressive camshaft the valves are going to stay out longer - which on a stock motor is fine - though you probably have longer rods and/or higher compression pistons to achieve your already higher compression, which might create clearance issues.

In short, you'll either have to A) Take some measurements and do some calculations, B) Take it to a machine shop, C) Plug it in and hope it doesn't pwn your valves, D) Take it to a machine shop, they can properly check it, D) find somebody with the same setup.

 

12.2:1 with a turbo, no wah jose , you'll send the cylinder head into orbit and your cranshaft to hell..

 

The D15B's cam timing is 9° off of the D16Z6's. I can't remember is it's advanced or retarded.
