13b and 20b
 

what's up to the rx-7 club which is the realist car club on earth!!!! i would like to know what is the difference between a 13b and a 20b?

the search button is at the top of the screen.....use it wisely.......

13b is a 2 rotor 1300cc, 20b is a 3 rotor, 2000cc (or close enough) found in cosmo's.

The 13B is a two-rotor engine, the 20B is a three-rotor engine. They use the same sized rotors and housings, so comparing a 20B to a 13B is the same as comparing a 3.0L 6-cyl to a 2.0L 4-cyl.

20b - 13b = 7b (Algebra Humor) :D

For more discussions on the 20B, you can read through our 20B subforum.

These external sites are also good.

correct me if I'm wrong, but don't the b's cancel?

20b - 13b = 7

<never liked algebra>

i think you have to divide by b....then add some 0s....

(20b-13b)/b +......=20 boobs and a remainder of 13

yeah...that looks right

say b = 1300 (hehe)


26000 - 16900 = 7b (9100)

26000 - 16900 = 7? that'd be impressive :)

Ok, so I didn't set it up properly...

20b - 13b = 7b +13b

20 - 13 = 7 + 13

b = better ;)

wait dont the b's add??? 20b - 13b = 7d?

just kidding...

d= im retarde D

if it was an actually algebra equation it would be 20b-13b = 7b :P

you guys are all backwards :)

would be 13b-20b = -7b

cost of 13b rew and 20b rew
 

what's guys!!!!!!! i would like to know the price of the 13b rew and 20b rew with everything include? (brand new and used).

i would aslo like to know if it would fit in a 1988 turbo rx-7?

umm..ok

Re: cost of 13b rew and 20b rew
 

Do all the calculations for parts, labour and time, write it down, and then double it. :p:

Re: cost of 13b rew and 20b rew
 

Yes, they will fit into an 88 TII, but a great deal of work is involved, partially because the engine mounts are different. Performance shops currently charge about $35,000 to rebuild and install a used 20B-REW into an RX-7.

interesting....

:beer:

do all your searches from the above links. also try http://www.20bvert.com we can't answer all your questions you're gonna have to search a little. it's not an easy operation, hence the hefty price tag of installation, unless you have a good source of tools and is mechanicaly inclined to do so it's going to be expensive.
