im feeling pretty sick, so dont mind me.

what are the benefits of sleeving a b16 to maybe something like a 1.5 or 1.4 liter that could probably rev out to 10k-11k rpms?

most people stroke a motor to gain torque through out the powerband, but destroking would do what to an already small displacement motor?

would destroking a b16 to handle even higher revs and very aggressive cams make it better for road racing, or would it be better to have a larger stroke for torque?

i brought up this idea because they sleeved a b16 down to a 1.5 liter and threw it into a newer style civic with coil packs and i was wondering what you guys have to think/say.

discuss.

 

resleeving a b16 to be smaller would be pointless as it would still have the same r/s ratio. so if you found a smaller bseries crank, which i dont think there is, then you could rev it higher.

but that being said, the b16 is still good to rev high, so it would be a pointless waste of money to get even less torque than a b16 already has...

 

they did that b/c that engine has to survive at 10-11000+ rpm for very long periods of time, they have to run flat out for several minutes.. and do it alot. chances are you wont be reving 12000 rpms steady for 5mins at WOT

 

they also went down to 1.5 liters because the class they are in requires the motor be no bigger then 1.5 liters so thats why they did it, If you recall the supercharged b16 car that goes over 200 mph is also a 1.5 liter. its all in the classes.

 

awesome. i didnt have the magazine and was wondering why they did that.

thanks

 

wow.. I've never seen nore heard about DeStroking a B16...

 

all lisa kubos drag motors were de-stroked gsR's, and were made to 1.6 liters, this is mostly done on forced induction cars because of the lack of torque

 

*edit*

someone beat me to it

Now wouldn't you want torque? Or would they just want higher end power?

good job nick, i guess you haven't lost touch yet.

 

i think the turbo b16 the kubos used was like a 12,xxx rpms motor, and pretty much if it fell out of boost was useless, she even said it wasnt **** till 3rd gear

Actually, the only reason for destroking a FI motor (other than increased rev capacity) would be to reduce side loading under high boost.

 

destroking would allow you to run more compression height, improving strenght and durability of pistons and rings, as well as piston stability.
