GSL-SE is 135 hp; Renesis is 238 hp with the 6 speed, and I think the auto version is 192 hp.
|
what's the difference between the 4 port and 6 port? is either engine easier to turbocharge?..i ask that since the turbo motors from factory are 4 port.
|
also the gsl-se motors are the same as 86-91 na's. 13b 6port
|
the car im getting (gsl-se) has an 88TII motor with 89TII rotors, with 9.0-1 comp. how many ports will this engine have? 4?...it is running n/a. does that mean that im missing out unless the engine is turbocharged?...if not turbo'd, would it be a faster motor as a 88 or 89 n/a from factory? how much horsepower would this motor put out (without taking into consideration the mods it has done to it? would it be closer to 146 hp like the 86-88, or 160hp, like the 89-91. remember it has 89 TII rotors....
by the way the engine is ported, has a weber ida carb, rb exhaust, and msd ignition parts.....so how much hp WITHOUT the mods? |
what does a COSMO engine mean?

When you go out and look at the jspec motors the cosmo 13b's are around $1000 less then the 3rd gen 13b's...I know the cosmo with the 13b was rated at 235? 230? hp and the 3rd gen 255... whats the differences with the block its self... are the ports different at all??? Why are the cosmo motors so much cheaper?
|
:werd: I've always wondered about the difference between the 13B-RE and 13B-REW...
|
s4 =87-88 =160ish
s5 =89-92=180ish both turbo from factory. Major difference are the intake manifolds and to a smaller degree the ports on the housings are slightly different I think. So in reference to the question, I would say minus the mods, the motor since it has low compression rotors from the turbo, with the s4 housings maybe 140 na. |

Yes the Cosmo was sold here in 92-93 I think. It came with the 13B-RE.
Also, for some reason I remember reading about the 929 having the 13B-RE at one time. |
in us it was no on the cosmo in any year but the mid 70s. a number of pamplets had the 13b option on the 929 listed but I do not think any were shipped here or avalible for purchase. mazda sales history does not show any new cosmos sold in can in the 90s. gray maybe.
|
The JC Cosmo (90-95) was ONLY sold in Japan.
|
how much power did the early rx 13bs make??
the 4 port n/a ones? |
The 70's cosmo came 13b 4 port non turbo. And i beleive there like at 130 hp...im not completely sure on that.
