b16b pistons in b16a

hi, will b16b pistons fit into a b16a? will it increase the compression ratio and would it be worth doing?

If you have the suporting camshafts,valvetrain,Intake manifold of B16B's then it would be worth doing.

but on its own not worth it?

what are you after? more power and torque? have you thought of changing ur bottom end? much better bang for buck

The BYP Civic ran a B16a with CTR pistons for along time and then the engine went into a road car,TUNING the setup is the key to getting the most out of them you will just need a 65mm TB,Toda headers free flowing exhaust,cyl head needs a good valve job,You would be best off running Toda Spec-A Cams with there valve springs,or BuddyClub Spec3+ cams and there valve springs.

thanks guys, gsipsi, your going to say put a b20 bottom on it arnt you lol? ive thought about it but i dont think im ready to do that just yet, im just throwin some ideas around before i decide on what to do, if anything. besides i figured a b20 would end up costing me a fair amount of coin.

yeah but your rebuilding a motor either way its going to cost you. For the gains you will get from hi-comp pistons, doing all that to a B16a n/a it just wont be worth it. Its smarter to just upgrade your bottom end to either B18/B20 and working that. Non-turbo-wise there is no replacement for displacement.
Do you have the B16B parts with you now?. If you can install it yourself, without it costing you anything on labour etc then yeah why not. But just remember you will need supporting cams to get the most of ur new hi-compression

my old eg ran b16a2 wit ctr pistons, mugen head gasket and toda b's.

went well for stock bottom end 14.42 @ 110mph (itr g/box, full trim)

110mph?

surely not...

**shmivic** · 20-01-2010 12:19 PM

was done nearly 5 years ago.

proof was on time slip, witnessed by many.

all about ratio

4th gear, 8400rpm roughly, 177kmh

then you must be a pretty average driver to take so long to cover 400 meters,

110mph is the speed good drivers hit through the traps when the run high 12's...

when i was running 14.4's with my 83 prelude, i was only trapping around 95mph...
