So for my head swap im debating if I should go with the Type S pistons, or 11:1 pistons.

I have been hearing mixed opinions from people so I am not exactly sure what I want to do.

 

Whats the compression ratio for the Type S pistons?

 

I believe its close to 11:1 but some people say they arent as good as some other high compression pistons.

 

you might also wanna think about gas prices...they arent gonna stay this low forever lol

 

Yeah who gives a hell I just wanna be faster haha

 

the type - s 4th gen prelude isn't 11:1, whoever told you that must really think highly of their low model 4th gen. Anyways not to diss anyone cause we all got preludes but heres your ratios on stock models:

4TH GEN PRELUDES: (1992-1996)
S-Type: All F22a motors: 8.8:1 compression (s-type prelude - 4 cylinder Accords
Si-Type: H23a1: 9.8:1 compression
Vtec: H22a1: 10.0:1 compression

keep in mind this is for completely stock internal engine preludes, and I can assure you unless you put higher compression pistons or something within that realm, that there aren't any preludes with an 11.1:1 compression

 

When did I say I have a 4th gen?

A 99 is a 5th gen and YES the BB6 jdm h22a pistons are 11:1.

STOCK in my USDM h22a4 I have about 9.5:1 compression.

 

what are your plans anyways, why are you geeting pistons.

 

Well I have a type S head thats on and I want some type S pistons to go with it lol. But im sure not going turbo with that compression and not being built. But I may just do a 100 shot because that seems to be a good idea with an H22

 

:slap:
H22A4= 10:1
H22A= 10.6:1
Type S= 11:1
