I think im going to get type S pistons for my 98 prelude h22a. It says that they will raise the compression from (10 to 1) up to (11 to1). So what sort of power gains can i expect and will i have clearance issues with the valves if im running stock Vtec cams? I also need to know if they will fit my stock block. Bottom line i dont know WTF im doing and i need to know if this will all fit properly.
-Thanks-

 

the type s pistons will be plug n play on your 98, they fit in the stock block on the stock rods and you will have no clearance issues. might wanna get some kind of tune afterwards, but thats about it

 

gains will depend on what youve already done to the car

 

around 10whp. It's not excatly plug and play. There are three different types of type s pistons. Type a, type b, and oversized. All matters according to your block. The oversized pistons will require a .25 boring of the cylinders.
