i'm wondering what is different in the bottom ends between the b16a2 and b18c1? what i know is that they have the same bore... b18 has more stroke.... so the crank is different.... but is anything else? like do the b16 pistons create higher compression?? or are the b16 rods stronger cause the b16 revs higher??

Blue Dream

rods and pistons are both different,

pr3 vs p72

the gsr also has a crank girdle to hold the bottom end together at high rpm's I dont know if the sir has that.
the actual size of the block between the c1 and a2 is different also....

punkindrublic

the size of all b series blocks was the same i thought?


and how come the b16a doesn't have a crank girdle as it revs a higher then a b18c does??

i would think that since the b16 revs higher that the rods would be stronger cause once your spinning more then 8000 the stress is so ememse and going to 8500 is a huge jump in actual stress in the rods?

Blue Dream

rpm isnt the only reason for stress

the biggest is rod - stroke ratio OR R/S

well put Blue Dream..

Punk there is are tons of differences between the different models some have a higher deck plate then others it all depends...

and Punk my bottom end is smaller then yours

punkindrublic

yes it is... my bottom end is bigger... and my gears are longer yet the complete package is so small compared to others :cry::cry:

punkindrublic

which bottom end is stronger then?

BIGA10k

they are different. they have different power characteristics. one has more torque. one can rev higher than the other. one is a taller block. one costs more to buy. bigger is always better.

b16 pistons create higher comrpession in the b18c block...it has more stroke to it the rods are longer and the deck height in higher....I'd say the gsr is build stronger...the only reason why the b16 has no girdle and can rev higher is because it has a small stroke to it..b18 has more potential anythign else you want to know....

punkindrublic

why didn't you have any major typo's or language in that last post?

dingus8

ya that is weird eh...I"m scared....hold me.....

i think the B16 has just as much potential!

and if u were to race the 2 B16a2 and the B18c1 that would definately be a driver's race!

but Mod wise, yah the GSR has a slight advantage!!!
i wouldnt say it has that much.....

but then again it come down to the ALL MIGHTY DOLLAR!

dingus8

the gsr has alto more portential...more displacement..its' harder to make torque than it is horsepower..gsr in the same car stock for stock woudl win hands down...allmotor adn FI has mroe potential basically you'd have to pay alot mroe $$$ to get a b16 near the gsr if both heavily modded...same for stock to...

you'd need to bump the displacement soem how sleeve it stroke it...for all out comparo (both modded to the tit's)

ok heres the reason why this thread was started....

i'm told the b16 head flows better then the gsr head... so if i were to buy a b16a2 engine... and swapped bottom ends wiht a gsr engine i would be further ahead then just a gsr engine would be correct??

i was just wondering how interchangable the bottom ends where... but seemingly they are quite different

dingus8

that's the poor mans type r...type r head is essentially a b16 head with better cams and a better intake mani....only problem wiht this is that it will a) cost more money
b)not entirly worth it
c)your compression will drop due the fact that the gsr has a smaller combustion chamber so you will lose power from this

d) your puttign in a head with less aggressive cams

so not really worth it unless you put atleast the gsr vavle train and cams into the head along with higher compression pistons (ctr's)

when its' all said and done you would have made better power with the moeny spent keeping the gsr head getting it ported skunk 2 mani ctr or better cams...tunign 200 whp easy....

seeign hwo you woudl be spending alot of moeny on machien work, pistons yada yada doding the head swap and build.....

imported_gatherer

just get a b16.... then later on build your own bottom end starting with a Payn Technologies 2.2 liter block

Payn is a great shop... how do you know about it Jason?

You should have seen the cars that were there.... there were swapped AND turbo'd Civics scattered everywhere like *** at a strip joint.

punkindrublic

where is this payn located?? and what about a webpage?
