Let's compare a Busa piston to a C14 piston...shall we? But, by all means...DO IT!
It's the hot ticket...just like those 12.5:1 MTC pistons you ran...

I think the fact that you blew your motor up like 50 times says something about the quality decisions you make. But, by all means, tear those motors down and rebuild them with a used set of stock C14 pistons!

i only toasted pistons twice . SO don't be hating since your girlfreinds busa keeps breaking from your mechanicing . and your shitt can't stay together ..
my shitt goes out and runs every weekend .. can you say the same ..

I'm not sure what you are talking about? We have never had a mechanical failure with the Busa. In fact, she made 21 passes over 200 mph on it, without issue.
Ironically, her turbo Busa had stock pistons and rods. Have you seen the photos of the 1st gen Busa pistons cut in half? They are amazingly similar to JE Turbo pistons. Unfortunately, the Kawasaki pistons do not seem to be as stout. Even my 12R pistons are more stout than the ZX-14 pistons. The 14 pistons also have top ring land very tight to the valve reliefs. From the photos I've seen, it looks like the C14 pistons suffer from the same issue.
12R and 14 Pistons:

Please post some details and measurements of the C14 pistons.

1bad...I've told you before and I'll tell you again........I circuit race a RACECAR (much higher loads than a bike due to the weight and drag) with a boosted ZX14 motor. It runs Falicon knife edge rods and MTC Pistons and yes it has survived 20 minute races running 11PSI of boost, lap after lap after lap and yet you keep saying that MTC pistons wont survive more than 5 runs down a 1/4 mile dradstrip??????
There must have been something very seriously wrong with your build mate!!
Temperature is the trick when boosting engines.....the difference we have found since we fitted an intercooler to the system is phenomenal!

john bull i like i told you over and over and over .. i did not use the same pistons you used . because i didn't have to purchase no 2 mm shorter rods .. nothing wrong with my build .. its just shitty pistons .. IF YOU WANT I'LL MAIL YOU ONE TO LOOK AT ..

SHANE my c14 pistons are in a motor waiting for install into a frame . i have nothing to measure .. but i really don't give a fuck how great a zx12 piston is to a zx14 piston.. BUT I'll never waste my money on pistons from J&E or MTC I KNOW we gain nothing from either piston running stock rods over the stock pistons .. you guys can do what y'all want I DON'T GIVE A FUCK . BUT don't try to convince me I'm doing wrong by using what I'm using.. 500 passes and counting vs 5 FOR MTC and 3 WOT runs for J&E turbo pistons ALL WITH STOCK RODS .. AND THE J&E motor was professionally built pro custom tuned and pro priced .. all i did was pick it up and ride..

Nop, they are MTC tall deck pistons 11:1 which are used with 2mm shorter rods.

They would still be 11:1 unless he used a different head gasket, milled the head/block, etc. They are meant to be used with the shorter rods.

Correct, 11:1 CR.
My advise to anyone running a boosted engine is FIT AN INTERCOOLER. I think that this is the main reason why so many guys have engine failures on turbo bikes + plus with a cooler inlet charge you will get one hell of a lot more power out of the engine.

Whats an inner cooler, and will it help a nitrous zx14?

You don't need a intercooler you just need damn good fuel and AFRs in the mid 11s

No, an intercooler can only be used on boosted engines in order to cool the pressurised inlet charge and the more boost you run, the more important it is to have an intercooler since the higher the pressure - the higher the temperature.
Although when running on methanol even boosted engines dont need an intercooler since the methanol is so cold therefore cooling the intake charge dramatically.

That is just counteracting the heat problem instead of solving the problem. Buy expensive very high octane fuel and run a rich mixture and yes like you said and yes it will work......but the heat problem is still there,,,,,and the hotter the inlet charge the less power the engine makes!!

and exactly were are we to mount an innercooler on a zx14 bike. and i have seen a bike specific innercooler and it wasn't cheap. and it had a long waiting list .. AND it was made for a busa and you was gonna have to jerry rig it onto a zx14 .
so next best thing fog the air box 20 shot

You could fog the airbox with a 20 shot, but it might be just as easy to use water/meth injection. That is very small and works just as well as an intercooler.

correct ..but i'd like to gain something if i'm gonna do it
i never used meth..so i'll stay shy of it .. but i have used NOS and know enough of what to expect and ive got NOS part stuff
