i hope you dont have any problems. do your pistons look like my old ones or do they have a better skirt? maybe JE came out with a new design... the pistons i had were from 2003 but still only had 8k miles.

 

at the time they were the only ones available


btw sorry to hear bout your motor

 

Those are some shocking photos. When your dad informed me the underside of the piston can cracked, I didnt realize the entire skirt had cracked off!!!

The Arias Extreme Duty pistons you installed will serve you very well...no worries.

 

haha yea im excited about tuning the car after its broken in

 

i was running 851 cp pistons ..im going with aries extreme now..

 

cool i hope everything goes well for u

 

here are the picts of my JE pistons.. they're different than the ones you have

 

Those are the good ones similar to the ones I have...

 

*sigh of relief*

thanks biggy.

 

yea those are alot different and look alot better. glad they changed their design

 

the thing is.. the build date on my pistons were from 2003.. these were prototype pistons made for Nissan Motorsports.. we've been camping on these in preparation of my motor blowing, but it never happened, so i'm just putting them in now along with some more parts.....

well. i'm sure you're gonna be just fine with the arias pistons..

 

No prob man.... What comp are they Chebosto??

 

The thing you have to relize is that at 10.5.1 is crazy high to run with any amount of boost and that the pistons were made for n/a not turbo...Sorry you had to go through this you'll be happy with the new pistons...

 

i believe they are 9.0 :1 ? i forget.. its been so long.. we have to recalculate it... but here's the specs:

 

yea im bout done breaking the motor in

 

I think the problem was more with you running 10.5:1 compression with FI than the pistons.......even though that is strange, 10.5:1 with boost=not the smartest.

 

that was all that was available at the time... like i already said

 

Its all about cylinder pressure..
More comp and less boost can give similar cylinder prerssure to less comp and more boost.

FYI our motor is getting built with 11.5:1 and a fair bit of boost

 

i don't know if you know this, but you can special order pistons for almost any motor in almost any compression ratio...........it takes about 5 mins to call someone like Race Engineering who can set that up with almost any piston manufacturer.

 

I hope you plan on running c16 all day
