overbore question
 

ok so im building a z6 currently. ive never built a motor before..

long and short of it is i was planning on just honing the cyl walls and rolling with stock sized vitaras.. there isnt a "ridge" to be spoke of ( between tdc and the deck of the block)... theres only a texture difference in the cyl wall.... which to me means there is minimal wear there


my question is this


how many of you jackasses have put a motor together without overboring and what kinda success have you had


i dont wanan invest all this time in this ---- and have a motor that smokes.. and id RATHER not overbore it becasue i already have pistons


i suppose the easy way to find out it to measure the bores but i dont have ---- to do that right now


so... whos ghetto built a motor and had it turn out ok?

Re: overbore question
 

get file to fit rings...ohh and this should be in Hybrid/Tech.

Re: overbore question
 

I pulled apart a used block, put some used pistons with used piston rings and have happily boosting 18 psi since :)

well that enstills tons of confidence lol


thanks

Re: overbore question
 

I did vitaras and it was slightly overbored...got tones of blowby because of big ring gaps. Get correctly sized rings and pistons, if piston-to-wall clearance is ok, then use the pistons and get good rings. I personally would say just do whatever you have to for a properly done detup. Don't ---- around with vital componenets

yeah thats what im thinking its gonna end up being.. i think i have a buddy with some oversized vitaras...

i just dont wanan deal with the hassle of having it bored and ----
