I am building an LS/VTEC with CTR Piston (Standard Bore). Which Piston rings are to be used with them???

As far as OEM Honda rings, do I have to buy CTR Piston rings??? (If so, does anyone have a picture with the part number???)

OR can I go to my local Honda dealership and by Civic Si B16 Piston wrings??? (I think they are P30 Pitons.)

 

the factory rings are real good just use those... ctr piston rings and b16a rings share the same part number

 

Are you sure??? not doubting you, i just don't wanna have to explain to the folks at Honda that I bought the wrong ones, and i don't know what pistons i have, lol.

 

hes right i have them in my ls/vtec. CTR pistons and b16 piston rings

, dunt have the part no handy tho

 

yeah same part numero, the block code of the part number for the standard and oversized rings is PR3 = b16 or generic b series.

Thanx guys

 

Okay, I just ordered my Piston Wrings today from Honda for my CTR Pistons.

The Part number on the receipt 13011-PR3-003 is for a '00 Civic Si.

Is that Correct???

 

CP has low friction rings with a nitrided top ring, napier style scraper second, and low tension oil that works really well.

 

If the car is strictly a street car, I will use onda rings when possible. If I am building a higher performance engine, I will use low tension rings to cut back on internal friction.

 

I NEEDED THAT INFO ALSO I WAS WONDERING IF U HAVE 2 MACHINE NE THING OFF THE CTR PISTON IF U PUT IT ON AN LS ROD I HAVE 95JDM B16A2 HEAD 99 BLOCK WILL THE PISTONS FIT WITH NO PROBLEMS OR MODS TO THE PISTONS WITH OUT ANY VALVE CLEARANCE ISSUES

 

You will need to machine 1mm of each side of the rod to squeeze CTR pistons on to an ls rod.
As far as clearance, with pistons like those of CTR's nature you should clay your motor to check for valve clearance.

does maching off a 1mm effect the strength of the rod or r they milling of the length of the rod

Nothing to worry about.
You can have your machinist machine the piston to fit the rod instead of the other way around. THat is how my CTR pistons were done.

 

so do the machine some off the bottom of the piston if so how much or do u tell them the amount u want removed

 

It is probably cheaper/easier to mill the rods than the pistons.

i got my rods shaved and put on for like 100 bucks
GOOD DEAL

 

so if i machine any off will i lose any compression ?

 

has nothing to do with compression... just whether or not the rod can fit in the piston. all it is is fitment.
