Hey guy's i currently have a stock b16a in my 88 Crx Si and i was looking into ls/vtec and i was wondering if the pr3 pistons would be good to be slapped on the ls block along with my b16 head. Anyone seen/heard good/bad stories? let me know what you think.

 

your gonna raise the compression a bit. never heard anything bad about it. prob a good idea

yea i know i'll raise compression,but just wanting to know if it's been an unreliable setup, any more input would be appreciated.

 

That's the exact setup I'm running. I say go for it. That bump in compression will give you some extra horsepower. Just make sure you run 91 octane and stock timing.

 

Do they just slip in or any needs machine work to get done? i know i'll need 91 oct even though i just run 91 on my b16

 

they are both 81mm so its a drop in affair

What rods will i have to use?

 

you would use your stock rods

 

Stock as in the b16 ones right?

 

no you would use your b18 rods

 

k thanks anyone have estimate Compression numbers i would have with the pr3 pistons on the ls along with the b16 head?

 

11.3 to 1

 

yea it's bout 11:3 to 11:4 to 1 the only thing i recommend getting new piston rings and get some new rod bearings then you'll be straight ur gonna love it, a great power increase....

 

what head gasket i need for this setup?
