13BRE or 13BREW
ok.. this has probably been asked.. :wallbash: but i couldnt find it..
ran across a screaming deal with someone here locally.. would you get: 13B RE half bridge ported, NEW S5 rotor housings, 3mm seals, 3rd gen manifold custom built to fit done by rx7.com just the short block, upper&lower intake manifolds. has not been installed since build. or 13B REW bone stock complete swap with efini turbos, ecu, wiring harness, 5 speed trans 280hp. approx 48,xxx miles they both are the same price.. i want to buy the 13b re but my daily driver is almost dead. and i need to get the car on the road. thanks in advance for your oppinions |
For a street car, I'd go with the bone stock REW (correct) motor. You don't want a half bridge, custom intake mani setup for a street car unless you're pretty hardcore, definitely not for reliable transportation/daily driver use.

the rew hands down!

The RE actually has bigger intake ports stock but both can untimately be opened up to about the same. The main benefit to the re motor is the better flowing intake manifolds, but then you have the issue of the throttle cam being on the wrong side and no provision to mount the idle air control valve.

goodfella, the car will eventually go pretty hardcore..(once i learn more about them. i still have tons of research to do..) sorry about just asking everyone this info that took awhile for everyone to obtain. but these deals will be gone by sunday and i dont wanna pass something up that i will regret. |
You don't have to run the iac, just car won't idle as well when cold.

what's the point of a 13B-RE with S5 housings? S5 ports are smaller than the 13B-REWs ports, the 13B-REs ports are larger than the 13B-REWs ports. At that point, you'd be better off with the 13B-REW than the 13B-RE with S5 housings.

Id def. go with the REW just for driveablity and reliablity, the half bridge will require a lot more attention and most likelyy will not last as long as the REW.

the ousings arent new.. they were new then got a big port job. i have looked at alot of ports on rotor housings. i have even bought a used stock housing and sent it in to be ported just to see how much bigger it gets..(may be stupid but its helping me understand the motor more) so they will flow well beyond the capabilities of the stock REW also i just found out.. the rotors are high compression. so the re motor will either put out crazy power when it gets tuned!! :) or it will blow up. :anger: |
isn't it a pain to get a RE into a fd? aren't the engine mounts the same as the FC?

+130 on the REW. Sounds like the much more reliable option.
|
cool. thanks guys.. i am gonna get the rew..
sorry for just asking these questions. i just havent had time to research the re and i have to buy one by sunday or they will both be gone. i know you all have done tons of research trying to find the best set ups for your own taste. And i appreciate you shairing your opinions with me. thanks again. Kc |
Isn't the "280HP" on the REW with Effini turbos actually ~305-315HP? 280HP is the unofficial limit in Japan. As I hear Mazda only stated 280HP to stay kosher, while the 0-60 dropped from something like 5.4s to 5.0s (vs. the original 255HP FD). Not all of that added HP is the turbo, though. Some is the exhaust, etc.

I wouldnt touch a 3mm motor, so one more vote for the REW
|
13B-RE . much better engine. my mechanic says so :P

There is no point to running that motor over the REW. Plus, a bridgeported, race built motor is a horrible choice for the thread starter in my opinion.
But the jist I got from it is that they can simply withstand more beating than the REW. I do agree with you though; a built motor (which is what you would want to do with an RE) is certainly not suitable for the regular street driven FD. |

yes goodfella thats exactly what they are.
i bought the REW complete swap today. it will sit here until i have the money to paint my car. (dam state wont send me my income tax refund check yet!! i got the federal just waitin on the stupid utah government) when i get it painted i will throw it in and go from there. i just converted this car to RHD.. it was a little bit of a bitch but not near as bad as everyone said it would be.. i will post up a thread with pics of it. soon |
