dont really want piston slap with vitaras?
 

so im going to do a vitara build on my d16y7. im curently boosted at 12psi the homemade turbo way. boost is like a drug need more!!!

my question is the stock bore 75mm vitara pistons, ive herd will give me piston slap? correct me if im wrong.

if i did 75.5mm pistons, is it posible to hone the shat out of it? if so, dose anyone have a piston to cyclinder wall clearance spec?? :y :y :S

Re: dont really want piston slap with vitaras?
 

you mean like honing out your 75mm bore sleeves to 75.5 on your own? Take it to a machine shop and have them bore & hone it to your specs

dont forget to take your pistons to the shop too.. 75.5mm isn't as accurate as inch measurement...

Re: dont really want piston slap with vitaras?
 

stock sleeves area already pretty thin, I would bore them any. you could keep you're 75mm bore and the 75mm vitara's and have the piston skirts knurled, ask you're machine shop about it.

thanks for your help guys :6 :6

I just ended up putting them in there was like a .006 piston/wall clearance, the machine shop I go to didnt have a knurling tool small enough for my pistons. Supprisingly they dont even slap all that bad, in the cooler months I drive it I can hear it slapping for maybe 2-3 mins after startup but after that its gone.

so you think if i had close to .004 with out curlling prob wouldnt make any noise huh???? :y

Re: dont really want piston slap with vitaras?
 

there was a topic on this before saying that piston slap is better if your looking for around 400hp because of expansion. i'll try and look for it in a bit if i get bored
