Hey guys, I've searched and I can't find a good thread with people responding to the question I'm asking about.
Has anybody put in v-tec pistons(ex.PR3) into a b18a/b non-vtec engine before?

reason I ask is because I know that with a d-series engine, if you install a vtec head, you have to run a vtec piston or you'll slap your valves due to the valve reliefs cut differently on the pistons.
I'm just wondering if it's the same for the B-series non-vtec motors.
I'm thinking of putting in PR3 pistons I have access to into my b18b and pickup some aggressive cams to work with the higher CR.

Any experience with this? thanks guys!

 

also interested in knowin the answer to this...

 

from doing searches...I haven't gotten a direct answer but it looks like nobody is really concerned with any problems running the b16 or vtec pistons in a non-vtec b-series.

 

yes you can, a lot of people do it. you will be fine

CR will be at about 10:8 with pr3's
CR will be at about 11 with p30's

Thought so...good to hear

using zealautowerks, says with PR3's the CR would be 11.37:1 and with P30's 11.59:1

still

I've heard that the c-speed calc is a bit off...and that zealautowerks information has been provided by a group of honda-tech and hybrids.jp members.
I just still use the zeal but the CR will be a nice bump over factory anyways

how do you like it? what do you have done to the head?

 

I've got pr3's in my b18b right now. Results from a compression test were 230 in all 4 cylinders. Make sure you run 91+ octane if you put them in. My old GSR'd Del Sol had 185 in all 4 cylinders for a comparisson.

pr3's in the b18b, any mods to the engine? or did you just install the pistons itself.

any feedback on the setup?

 

Very interested..

 

what are the pros? cons? of using GSR pistons??? and what else do you need to make this happen?? any other internals?? and can you use aftermarket GSR pistons, or OEM???

Only the ctr pistons in the c-speed calc is off, everything else is on point.
