Topic: Pistons for a 22re? .50MM over

[dov'd85]

i am looking for some .50MM over pistons for an 89 22RE i want as good as or better quilty as stock and if possible lighter and stronger? are weisco's any good? i no they are not a very good piston for a snowmobile, but maybe thats differant for toyota's?

thanks for any info

stock is 92mm   so  where are you getting 55mm oversize?
do you mean .055 oversize??  they make .020=.50mm, .030=.75mm, .040=1mm, .060=1.5mm

[dov'd85 [OP]]

sorry .50mm i want to keep my compression ratio right around 9.3-1, 9.2-1. and i want a forged alluminum piston
thanks

Are the 22r & 22re pistions the same? I have a set that has about 2000 miles on them. Long story short, the block wasn't cut right & the piston rings wouldn't seat. I took the pistons out & scraped that block & went with a stock bore that I had laying around.

I have a set of new .50 over pistons I may be willing to sell   No rings, just the pistons.  I'll hafta check and verify that they have the piston pins and such still.

[kneedownnate]

Pins and clips are there.

A .020 overbore will have no effect on compression ratio or power, and will only give you another 25cc or so.

like i said i want a comp ratio of 9.2-9.3 to 1 basiclly stock, i don't want to raise the compression any, it will make power and were i want it,
 not in the high RPM's

i am looking for a company that makes the right pistons for my 22RE

thanks

all you need is a stock type piston in .5mm  size,  any  NAPA  can  get them for you,  many might even have them in stock

Aisin aka Toyota oem  in a .5mm  size

yea i can get Original pistons, but i want something that is going to be just as good of quility but alittle lighter, what about weisco pistons or cp diamond?

[LOL @ IFS]

Why do you want lighter?  I mean, there's nothing wrong with that, but since you're not after HP and RPM, your light pistons won't really do a whole lot of anything, especially if you don't give attention to EVERYTHING else.  It's like an underdrive pulley on an otherwise stock engine- the gains are so miniscule and is really just a waste.  If you want to spend the time finding light pistons that don't up your compression and that are the same price as normal pistons found through Engine Builder and 22re.com... you're certainly entitled to do that, but I'd spend my time elsewhere, like taking my time with the engine build in a climate controlled environment.

i am not skipping any details i just don't want to raise the compression for reasons you may not understand... i am doing extensive work on all the little detail, balancing the whole assemble with my clutch cover, blue printing everything, alot of port work on the head and intake plentum aswell as the intake runner, pay attention to detail and all the small things add up,

i have rebuilt toy motors with eng bldrs kit's, i am not looking to just "rebuild" this one, i want As good of quality or better than Asian.

[LOL @ IFS]

As in, I don't have the mental capacity to comprehend your reasons, or simply that you haven't given us the entire picture...?

Well I know I would not understand. thanks for not burdening me with the details.

You mean wiseco, not weisco   Had great luck with them in the motorbikes but haven't heard much about them for toyotas.

[79coyotefrg]

as far as i can remember  the Wiseco  only come in 10:1  for a 22R  and are a little over $100 EACH



if your not going to be running  20 psi of boost  your  throwing money  in the toilet 

[dov'd85 [OP]]

no i am not knocking on anyone i am just trying to explain what i am looking for, i called wiseco and they want $140 a hole, i am not looking to spend that much money if no one makes a better piston with the same compression ratio as stock pistons (9.2,9.3 to 1) for the 22RE, that are around the same price, then i will go with original piston.
