Piston Size Help.

["BLAHH"300!!]

HEY GUYS.
around summer time i will be going into my engine to drop in a hi-comp piston, cam, valves, and springs.
i need to know what is the largest piston i can put in a stock bore cylinder? cani only put the stock size (hi-comp) piston, or can i remove the sleave, and up the piston size? i DO NOT want to bore.

if i can remove the sleave, what would be the pro's and/or cons of doing so?

also, on a 300ex, what size piston would i order if i removed the sleve....

what would an average price be for boreing the cylinder to maybe a "true 300", or "305" ?(i want a rounded price for just boring the cylinder)


help me out...

If you dont want to bore it then you can only go with a stock size piston.Its around $40-$80 to bore the cylinder.

THATS IT ?!?!
man i was thinking like 200$ bux or something...
40-80's not ****zel....315cc it is then...

its about 150-200 for a new sleeve then you have to buy a piston. i would guess you are just looking to bore it out and had the two confused.

prob 310 or 315 i guess.

all the local dealers by me are retarded and want 600 to bore to a 416 and put in a piston:huh

look in the red box (it's too small for me to read the yellow stuff)

297cc BORE KIT- #00267 $212.50----76mm Forged Piston, 13:1 - 10.5:1 Compression. This kit bores into the stock liner and comes with piston, pin, rings and circlips. 318cc when used with our stroker crank. (i think this is what i want...

"this kit bores into the stock liner"
does that mean it only bores out the stock sleve??

313cc BORE KIT - #00271 $315.95---78mm Forged Piston, 13:1 - 10.5:1 Compression. Requires re-sleeving. Kit comes with piston, pin, rings, circlips, head gasket and sleeve. 335cc when used with our stroker crank for the 250X & 300EX. 342cc when used with our stroker crank on the 300 2x4 or 4x4.

"re-quires resleeving".
so this one bores out the stock cylinder??
i think the 297cc kit is what i'm after, or something like it....



12.7mm STROKER - #16078 $277.55 ....??

12.7mm STROKER with HEAVY DUTY ROD - #16078B $545.55..??

the powroll 297 kit is the largest you can go without resleeving..or atleast largest powroll offers without resleeving....you simply have your cylinder bored out to match this piston...this kit is a rip off...lol all that is is boring your cylidner 2mm over...u can simply go an buy a high compression wiseco piston that is 80 over which = 2mm and you will have a 297.....and wiseco pistons are like $100 bucks this kit is 200
