Im planning to use ctr pistons with jun3s.

Was just wondering if these pistons can handle revs over 9000?
will it be safe?

and also should i get a spoon headgasket or just use the stock one?

 

properly tune...9000 should be ok...

 

but not over 9000? i plan to take ge tit to 9500??

 

I'll be more worried about your valvetrain than anything else.

yes, pick up some ef-1 springs, valves and retainers: They will handle way over 9k and are guarenteed that not to break, when used together

 

I have jun valvetrain already(valve springs and retainers)
so they will rev to 9500 redline np?

thanks

 

built properly the pistons are fine.
ditch thevalvesprings though.

Why do you want to rev that high, are you sure that you will still be making power there?

 

yes they are fine. worry more about your valve train if you plan to rev that high.

side note, dont try to set a goal to rev to 9500 just so you can say you can rev that high. build you motor and set your rev limit where you motor stops making power(youll know by looking at your dyno charts). no point in revving to 10K and risking damage to the motor if your motor only makes power to 8500. catch my drift?

 

yes np i know wat u guys mean i was just wondering cos a friend told me ctr pistons cannot handle revs past 9000. and i have "read"(not experienced) that jun3s make power past 9000+


thanks for ur help i will try to get toda or crower valve springs if i can.....

I would avoid crower if I were you. Im currently running crower but have heard too many horror stories so Im gonna switch to something else soon.

 

get ef-1 valvesprings.

what's wrong with the valve springs? i have mine for over 80k miles.

 

I would worry about Piston to valve contact.

shouldnt be a problem unless the head or block was seriously milled...mine is NOT a problem.
