how much of a gain will i get by putting in type r pistons in my k20z1?

 

oem sized or .25 over sized... im supose to gain around 12 to 13 whp (doin some math and what not per liter divided by somemore numbers ... ) im running .25 over in my A2 gains to be in the 12-13 hp range from what ive been told... oem sized pistons i dont see gaining very much at all .. a little from the higher compression

 

they even sell .25 rings on the oem acura store. what us car do they come in? to used these over size to bore my block or would they fit right in?

 

they sell the rings becase dealers sometimes have to use them on remaned blocks that had to be bored... .25 over sized means the block must be bored .25 over to let them fit .. other wise they would be stock bore.. my pistons would not fit in a stock type s ..

 

do you honestly think it was worth it

 

I would say 5-10 whp

PM'd btw

 

i dont understand how the 05 type S has 210hp and the type R has 220hp even though the type R has a better im, diff axle back, higher compression pistons and a better 4-2-1 header with a better flowing cat. does the type S have somthing that is better than the type R ?

 

TS is not 210

 

its 210 before the new hp rating same thing as the type R correct?

 

peak #'s don't mean **** LOL

Thats correct. The JDM K20A actually has 220ps which means the actual HP of the JDM K20A is 217hp.

220ps = 217hp
