Do you know what kind of pistons these are?
 

Well.....I got this motor in a trade and put a turbo on it being told it was a stock b18b1. So yeah I blew it up in a couple of days just driving around on a basemap not giving a ---- about it. I pulled the head off and discovered these. (dont look like b18 pistons to me...) Anyone know what these are from these photos by chance?

you know what failed yet?
not why thats obvious

Re: Do you know what kind of pistons these are?
 

something happened in #1 cylinder. It stated leaking oil out of the exhaust port on that cylinder and running like poop water. It looks like the ring took a ----. Theres a little bit of wear on the cylinder wall but everything still rotates. So hopefully nothing to bad. I am going to pull it apart and take a look.

PCT's for sure.... very boost friendly :P

Re: Do you know what kind of pistons these are?
 

PCT's?? oh nevermind I googled it..

Re: Do you know what kind of pistons these are?
 

pct's . that ---- had monster compression

LOL I think that happened to Abaz(J FRank) on here too. CDM spec ctr pistons. Surprised it lasted a couple days.

i remember that build, he was being ultra conservative too

Re: Do you know what kind of pistons these are?
 

He didn't know either

It was a flatrate job for some young kid

Re: Do you know what kind of pistons these are?
 

i was in the car for the ride, was ------ slow. dont think it even got half a pull before it was done. just started smoking more and more lol... came up to a stoplight and smoke was just coming in threw all the vents/floor/whatever.... DONE, turned around and went back to the shop...

Good good. Them things make a hell of of quinch point. Personally never seen something like that except on a SBC. But that motor was a dirty girl even for a v8.

Re: Do you know what kind of pistons these are?
 

Yeah I remeber that it was in a purple hatch. they did the turbo install and it cracked the ringlands on the first pull. upon taking the head off they found type r's in it.

Re: Do you know what kind of pistons these are?
 

domes = fail

present race technology stays the ---- away from them motor, spray, or boost. Do some research on it...
