Ok, this seems to be a good choice. Can someone explain to me good/bad of this engine. Is it the best 2 rotor engine? What kind of power could it max out to? Any and all information is greatly appreciated. Thanks.

stock intake ports are better, but the stock exhaust ports are smaller. Not necessarily the "best" motor. It still displaces the same amount as any other 13B...just has different intake runner sizes.

yup jspec hit the nail on the head. you can port a cosmo engine slightly bigger than a rew... but not much

4RotorRocket 08-23-2003 03:16 PM

So why wouldn't the RE be the better engine then?

Nobuteru 08-23-2003 04:17 PM

how much power can the RE handle?

vosko 08-23-2003 04:34 PM

you have to mix and match to make an RE work... why bother if you don't have to

What do you mix and match exactlly?Someone said something about this before but that was awhile ago I cant remember. https://www.nopistons.com/forums/pub...1047683561.gif

Like I said...just like any other 1.3 liter displacement rotary engine.



Are you talking about stock or ported? If your talkin ported, then the 13b-rew is just as good.

Nobuteru 08-23-2003 06:37 PM

Yea, the REW is just as good, but isnt as easy to get into my FC as the 13B RE. Ans it will be ported. Is it just a waste of time? Should I just stick with a 13BT? I want a lot of power. Im going to start off easy with it, but def boost up to a lot more soon after. I need suggestions, info, anything you can tell me. (Sort of a competition with a guy with an R33 skyline)

the RE is kind of a half and half engine. Half 13bt and half 13b-rew

Nobuteru 08-23-2003 07:31 PM

So would the RE handle more power than a 13BT?

yes

Nobuteru 08-24-2003 01:03 AM

How much power do you think the RE would be able to handle?

vosko 08-24-2003 10:26 AM

as much as everything else in your car can support

4RotorRocket 08-24-2003 10:51 AM

Back to the half and half thing,what half would you take from the RE and put on the REW?I know what half but I dont know what its called.

Nobuteru 08-24-2003 11:42 AM

So do you guys think the RE would be a better choice than the BT? Strength and power wise? How much would an REW install on my FC be? Is the REW the best 2 rotor? Like i said im looking to start of with lower numbers (400+ps) then move up to a better setup. I would like to know what would be the best engine to use that would hold a lot of power without problems. If there are things that i can do to strengthen my 13BT, can you guys tell me? I would appreciate that. I would also like to know where i can get brackets to setup a V mount in my FC. What turbo do you guys feel would best suit my needs? I was thinking of a T66, T04, 60-1(dont know if the 60-1 would give me the higher end power) Do you think i should get all new parts for the engine (rotor housings, rotors, etc) I would also like to know what i would need so that i can extend the RPM band without worry of blowing it. I saw gurumotorsports has a 2 peice E-shaft, hardened stationary gears, what else can i get? What else should i get? Thanks for the help.

stick with the 13bt, port it and put fd manifolds on. getting a different engine would just decrease your ratio between power and money.

4RotorRocket 08-24-2003 09:01 PM

I was thinking of doing this with the 10th AE im getting but I wont attempt it until my moneys right.Nobuteru do you know what I asked?

rx7tt95 08-24-2003 09:05 PM

If you swap in the REW stationary gears, the RE is JUST as strong as the REW motor and stronger than the BT. The REW runners can be ported larger than a fully ported FD engine, especially on the primaries. The only problem you may have w/the RE is finding replacement plates if needed. But core engines can be had much cheaper than an FD, in the neighborhood of $500-$600 which is about the cost of new housings which you should use if doing a rebuild anyway (ask me how I know!).

So just swap the stationary gears on the REW?Is the engine in the FC a 13B or no?

rx7tt95 08-24-2003 09:21 PM

the FC's engine is a 13B but it's a 13BT. There's a bit more material in the plates in specific locations on the later model RE and REW 13B engines. Swap the stationary gears AND the FD oil pressure regulator.
