I was wondering if getting just Type S pistons and rings would be beneficial and safe on my stock internals.. thanks.

They would be fine. They are 11.0:1 and would give a nice inc in power. Since you wouldn't be going with a forged piston there is no reason to resleeve.

The pistons should be fine with stock internals... but it may be a good idea to retune the VAFC for the higher compression.

thanks guys, you suggest getting new rings as well or can I get away with just the pistons?

red92si

Anytime you get new pistons, I would recommend you replace the rings.

so what if you get type S pistons and rods. Do you not have to replace the sleeves, even if your car has around 90k on it????

you only need to resleeve if you put in forged pistons, rods won't affect that, though with 90k on the engine you might need to get the cyl. bored and get oversized pistons depending your cyl. walls shape.

my car has 120,000 miles on it.. so I should get new pistons/rings and rods??

concLude

question: i already am blessed with a jdm 10.6 CR and to boot the engine only has 11,000 MILES, thats right MILES not KM.

anywayes i thought the type S pistons were 11.1:1 ration not 11

would it be worth it for me to rip apart the block for just a .5 increase, or would a spoon gasket help better? my goal is 11.4-6ish CR

thanks for any imput

they are 11:1.

That would be a huge waste. Better off to shave the head or headgasket. Don't touch the pistons if you don't have to.

The Spoon headgasket will either raise your compression by .1 .2 depending on which thickness you buy (1 ply, 2 ply). So with a +.2 headgasket you would be brought up to a 10.8:1 CR. If you really wanted the extra .2 to make it 11:1, then you could mill the head down accordingly.

If you want to end up with an 11.4, or 11.6 CR then you would either have to buy aftermarket forged pistons, or buy the TypeS pistons and still do the milling and addition of the thinner headgasket. The problem there is that by milling the head, or doing anything that brings the combustion chamber down closer to the top of the piston... you could end up with the valves hitting the top of the piston.

Although with forged pistons, you would have to resleeve the block.

Hope I helped

so with all my basic bolt ons done.. i/h/e/p and a vafc.. do you guys think type s pistons are a good next step in my na build up? After I save some money i am gettin a DPR job i have talked to them a lot, and a hondata system later on.

Dragazn

Is type S piston a drop in or and mod to the rod on US lude h22a4

you mean by resleeve is it mean reservice cylinder wall make it smooth or darton sleeve.

mcgill

so do i have to get new rods or not if i get the type s pistons?

Satan_SRV

You have to modify an H22A1 rod to accept a floating wrist pin design piston, get it re-bushed. H22A4 pistons inc JDM ones are floating...

BTW Spoon Headgaskets are lame, you cna just shave a stock head gasket to the width you want.

how much would that cost?

mcgill

where can you get a h22a rod re-bushed?

red92si

when I say resleeve... I mean sending your block out to get sleeves installed.

H22A4 means no mods to engine therefore I can just slap in the pistons,tune and be good.
