maximum piston to wall clearance for 75mm vitaras?
sup.
just wondering. what is the maximum piston to wall clearance to run on 75 mm vitaras... thanks |

How much boost do you want to run? with my 81.5 dished wiseco's Im running .035, but im gona run 25+ lbs.

Re: maximum piston to wall clearance for 75mm vitaras?
When the pistons with rings on slide in by hand you know you have reached it...
Seriously though, on 90dx's vitara build, piston to wall must be .065+ they move all over the place in there. |

Maximum is whatever it comes out at :P If you car about diesel sounds then go 75.5.I just through them in massive ring and piston to wall gap stylz :-X

Re: maximum piston to wall clearance for 75mm vitaras?
I think you guys mean .0035 and .0065 not .065
.250 is a 1/4 inch.... |

.250 is a 1/4 inch.... .0035 = 350 thousands. |

.0035 = 350 thousands. .0035 = 3 and 1/2 thousandths. OR 35 tenths in machinist lingo. |

All I know is my ---- slaps like your mom's ----- lips in a wind tunnel (even when at full temp) and I have 190,180,180,190 cold compression on a 75.5mm CP piston build.

.0003 would be 3 tenths. Since most of the time when machining your talking thousandths, you don't typically think of a tenth as being .100. |
Re: maximum piston to wall clearance for 75mm vitaras?
I run mine at around 35 tenth fifths of a mil

Naw. When Machinists say tenths, they usually mean .000x. It's short for "ten-thousandths".

Anyways my wisecos were set to .003" at the shop, and when the extra coating wears away, it ends up at .0033" (according to the phone person). I get no slap on cold startup, and minimal blowby (no more than stock). I did allow #2 and #3 to get an extra .0001" of clearance since they run a tad hotter. As for vitaras, I'd go with .0035-.0040". The 75mm had a LOT of play in the blocks I tried them in, and people ran them fine that way. Just don't expect another 50k from cylinders/pistons with a .0065" clearance... |
Re: maximum piston to wall clearance for 75mm vitaras?
YOu have no way to adjust for piston to wall with standard bore 75mm vitaras.... so its just throw them in and be happy...
In my car i had .006 with no problems, no blowby, no need to be re filling with oil at the end of the month..lol .. JFK78 is running .008 clearance and he has 471whp.... |
