tosted a b17 piston ??? options ??
 

pissnuts toasted a piston in his hatch i need to know if there is any other b-series piston i can through in there that will work, i cant find and b17 cheap pistons.

Re: tosted a b17 piston ??? options ??
 

i believe the pr3 piston will work but will raise compression ratio's. I wanna say its even with the deck but not really sure

Re: tosted a b17 piston ??? options ??
 

i got a spare set of pr3's in my garadge that would be bad ass if i could just use them.


i wonder if i can just use ls ones for a nice low comp :y

Re: tosted a b17 piston ??? options ??
 

stock c/r is 9.5:1 in a b17
pr3's will raise it to 10.7:1
pr4's (LS pistons) <--duh...will lower it to 9.0:1
boost begs for the pr4's

Re: tosted a b17 piston ??? options ??
 

you like your comp calculator ??? fag boy


the rist pin height is to high on a b17 i dont know if the pistons will stick .030 above the block

Re: tosted a b17 piston ??? options ??
 

lol ohhh the piston my nitrous blew 12 months ago but just now lost compression ???? lol you guys are funny small turbo+ bad boostcontoller = choking motor in 80 degree weather

Re: tosted a b17 piston ??? options ??
 

it was 5 months ago




its probably because corey like running 90000* advanced on his timming

Re: tosted a b17 piston ??? options ??
 

so you think we can jus run ls pistons ??

Re: tosted a b17 piston ??? options ??
 

i hope we only got like 986738976248967 sets sitting around

Re: tosted a b17 piston ??? options ??
 

pictures?

Re: tosted a b17 piston ??? options ??
 

anyone know if you can run ls pistons in a b17 ith b17 rods ... should be ok cause b16 dh is .020 and the ls's is .030 which is less which will give you about 8.8 c./r. im just wondering if the wrist pin is in the right location on the ls pistons

wierd thing was no sign of detonation but i wasn't in it when it blew so who knows ...
compression reulsts are
150 150 0 150 :P

Re: tosted a b17 piston ??? options ??
 

i already found that i think that guy is a dumb ass though

Re: tosted a b17 piston ??? options ??
 

pretty simple take the piston off if you guys have a press if not run down to the machine shop and heat the rod up get the new piston in


Throw it in and see if your even with the deck shouldnt cost more than 15 bucks for them to press of a piston and time to see if your even with the deck.

Re: tosted a b17 piston ??? options ??
 

i think were just going to do it im going to measure the wrist pin hiegth with a micro meter the should according to the info i found and should make the compression 8.8:1 which is perfect for a gm8 @ 15 psi

Re: tosted a b17 piston ??? options ??
 

lol you dont have a micro meter. but i'll bring mine over

Re: tosted a b17 piston ??? options ??
 

lol im sorry the guy across the alley has one (scott) ... retard :1 plus i already found out that they will work
