Hi guys. Im new to this forum so hello. I just recently acquired two used but in good condition motors. One is a 13b-re and the other is a 13b-rew. I know that the re has a better intake system, but the rew has better ports. The re has a stronger rear plate around the dowel, whereas the rew doesn't. What i am trying to find out, is what parts should i use from both motors, to make a strong, reliable motor. I want to make at least 500whp from this setup, and i would have liked a half-bridge on the motor. GT40R turbocharger,1000 pri 1600 sec, power fc, walbro, fpr, fmic and the list goes on.....Any suggestions on what i should do in terms of building a motor to support that kind of setup??????

 

have it professionally done

 

Half bridge?

If its not a daily driver full bridge that sucka!. Do a 4" exhaust and race gas. Good luck with it!

 

well i was thinking half because i want to have a streetable car. The car already has a twin disk, lockup rear end, and full suspension. The car is an ex drift fc3s, and traffic here is like purgatory....I have heard some horror stories of bridgeported motors, and i was thinking maybe halfbridge would have increased the reliability slightly....sorry for thinking in a straight line...lol

 

Build the 13b-re, it has bigger runners than the rew and it fits into the fc a hell of a lot better.

 

Make sure when you build the RE that you port out the exhausts ports as the REW has much bigger exhaust ports then RE as standard.
I know the REW has 3 window bearings and hardened stationary gears, does the RE have the same I wonder? so you may need to swap the gears/bearings across from the REW to the RE

 

Run the REW gears and bearings, you can port the REW plates to match the RE plates pretty much so port match both sets of plates and run the RE upper and lower. Should be fine.

 

More fuel pump too. The little Walbro won't cut it. CJ

 

well i looked at both of the motors today, and i did see that the re has much bigger intake ports, but has smaller exhaust ports than the rew. Also i was going to use the re center plate so that i can use the mount kit to make life a lot easier in terms of dropping the engine in the car.

 

You won't need the 1000cc primary injectors... 850's will do fine. Go with a dual fuel pump carrier. As for anything internal listen to the other guys.

 

500rwhp isn't going to need anything special as far as your engine goes. In fact, your probably better off with stock apex seals. Just clearance the engine and that will be enough.

 

^ Ernie, could you possibly elaborate on PFS's "race clearance." I always wondered what was entitled in their specs...

 

If I knew how it was done, I would being building my own ****! lol...No, its taking material off the rotors and making sure everything is in spec, as well as making the motor "loose" enough to make the power you want without rotors smaking, pinching side seals, etc...

 

For a big boost/high hp engine you have to clearance it looser. Definitely adds some time to the building process...

 

Definitely the only time you'll want something loose in your life...

 

Just to clarify, you *cannot* "port out" the RE exhaust sleeves. They are hollow.

Do what I did and fine a blown 13b-REW and snag the exhaust sleeves. They are solid and if you ever wanted to go bigger you can port them.

 

Yeah either pull sleeves out of junk housings or use the rew housing if they are in good shape.

 

well guys got some bad news........upon further inspection of the re block, i've found out that the motor is blown and i think the probable cause is a broken seal. And i think you guys know what goes hand in hand with broken apex seals....so that leaves me with the rew block. I think it would have been better to use the rew block and just port match and use the re intake manifold
