is .40mm overbore to big for a d16z6. im also using a block guard

 

i have another question. i bought a set of pistons from a guy but he doesnt have the rings for .40mm over. where would be a good place for me to look

 

don't know the max bore on that engine but if you use the search feature on this fourm or even google it i am positive you will find your own answer

far as rings for pistons look for a place that sells pistons

you should research your questions b4 you ask them

 

first of all .4mm doesnt exist ( isnt a regular overbore size)

u probably mean .040 inches which is considered 1mm overbore which is 2 much for boost in my opinion
try the dealer for rings

200hp no problem but 300 ur really pushing it
dont ever plan on detonating

 

yeah i guess its .04 overbore. is it too big for a boosted engine. well we will find out

 

i'm going .040 over on my built mini me. plan on running 15 psi daily

 

better reinforce those sleeves or get some new ones!

 

well i have a block guard.

do u think that a t25 (greddy 15g) will support 225hp and will it pull til redline and 15 psi.

 

t25 might get you 225. those start to run out of air up top. and i don't see why you would run more than 10 psi on that small of a turbo. 15 psi is way out of its efficiency range.
