does anyone know what are the differences between the b-series block besides the bore. and which of them can be bored and sleeved the most for 30-35psi of boost

urbansi

Well there is differences in stroke for one. But asside from that, you can sleeve any B-series motor and push north of 40 psi if you want.

If you really want a good power plant to go with, look into an 84mm 2.0 GSR block.

And then go from there, if you look on Mase's website or Evans tuning website, you will see that like 80% of the cars are built GSR 2.0's.

B18C has a block griddle and piston oil squiters.
B18B has neither.
Both have the same deck hight.

civic_eg-o

so the jdm b18c has the girdle and piston oil squirters, or any b18c being gsr or the itr

civic_eg-o

does anyone know about this info on the b20?

The B20 has some issues when sleeving.The LS (b18a,b) is a better and cheaper choice for sleeving.

All should be fine as long as they are sleeved properly. The vtec blocks b16, b17 & b18c all should have oil squirters. But some remove the squirters to run longer stroke cranks. You can use the b16a block with the ls crank but will need to remove the squirters.

If it you are not sleeving it do not do the b20.

so if i put ls rods and crank into my b18c block would it be a god idea to remove squirters, yeah or neah, just curious cause i'm about to build another motor, thankx

crxhybrid1320

I believe so and it increases the displacement slightly.

in order to use the LS crank in a B16 Motor i believe you have to deck plate it.. the B16 block is much shorter height then GSR / LS ..correct me if im wrong

civic_eg-o

i'm sorry but you are wrong on that one. the blocks have the same deck height but if you have the b16 internals you should keep the pistons (higher compression) and put in the ls crank and rods (more torque,more stroke, displacement). the disadvantage to higher stroke is more wear on the engine and less cylinder dwell time because of higher piston speeds, and there for are not made for very high rpm, but you shouldn't worry too much about this since your situation isn't extreme. formula 1 engines and motorcycles have less stroke than street and drag racing cars that is the reason they can rev up so high and gives them high hp, sacrificing torque (which is not as important to them because it doesn't take much to get them going)

i din't really explain my question too well. what i was refering to was the difference of the b-series blocks(not the internals) and not the specs on them either, but the advantages of one to another that they have. and which can be bored out the most ans still handle 30-35 psi of boost. B17? B18A? B18B? B20? b16a? B18C1? B18C5

You have to remove or modify them.

Gojira D.O.T

they do not have the same deck hieght,b18 blocks are 15mm taller than a b16 block

civic_eg-o

NO, you are talking about crank shaft stroke not the block deck

civic_eg-o

and it isn't 15mm it is 11.6mm stroke difference between the ls and b16

civic_eg-o

but i could be wrong so i'll check on that one

wantboost

iTrader: (2)

no. the DECK HEIGHT of the b18's/b20's is taller than the b16. to allow for a longer rod with the longer stroke.

you ask for help and then jump on people saying they are giving misinformation when they arent.....

civic_eg-o

i am not getting on anybody. if you don't want to answer a question don't answer it, but take off your *** tight pink thong and shut up.

Correct. Except I believe the B16 rod is actually longer than a LS rod. Correct me if I am wrong. It is that short *** stroke and long rods that make it so rev happy.

And yes the B16 deck height is considerably shorter than the LS/B18C

Go Away with that attitude.

turbotime

you can throw a b17 crank in a b16 block to increase the b16 stroke. The b16 and b17 are the same cast tho, b18 is taller.

*edit: b17 crank in b16 increases stroke from 3.047in(b16) to 3.205in(b17)

**edit: oh and u need the b17 rods too!

civic_eg-o

a big thankyou to every body with good replys and for correcting me

ValleySyder

i could of sworn i was rigth with the b16 height being shorter by a matter of 14-15mm..

civexturbo

Don't forget that the b20 block is already an 84mm bore opposed to the 81mm of the other b's
