guys,

my first question is in the 13b-re are the rotors different than those in the -rew? maybe lower compression?

If so is there a place to purchase the rotors and housings for the re (and the lim, uim)?

Whenever i search for the engine i see places that import the engine, with turbos... but what if you want to go single right away?

i would really appreciate any help at all

thanks

 

Drag International. Ask for Larry. Tell him Alex sent you. He's in Davie, and just got a fresh shipment of engines.

 

directfreak,
thanks for the info... damn that place is right around the corner from me! awesome. So i take it they import used jdm engines? i will call them and ask more specific questions.

oh yeah.. v8 killa.. what a sick car i hope to see it around someday simply beautiful


so anyone know about the rotors in the 13b-re.. how are they different from those in a FD? Just trying to get a good understanding of this engine...

thanks again!

 

rotors are compatible with fd's. they're the same compression and weight, so counterweights are compatible too.

i don't know if they're an actual different casting, but they work, anyway.

 

yeah after doing some searching they are the same rotors... any know of other places i could buy the housings and irons alone?

thanks for the help

brian

 

you don't want the housings. they've got that restrictive exhaust sleeve in them.

just use s5 or fd rotor housings. i've got no idea on the irons, other than the forums.

 

Then you unbolt the turbos and pitch them, easy.

 

haha, yeah i think ultimatley that is what i will do, i wanted to try to price out and see if i could save any money building the engine up from scratch. and going single.

So you guys would agree to use the REW housings over the RE? But you the RE irons?

 

yea, but only if you have the RE intake manifolds.

but since you're building it, you can port-match the rew irons to the re manifold and life is all good.

 

ahhh.. i think i left out that this engine will be going in a FC, so i have to deal with the motor mount issue. thats why i need the parts from the RE. at least that is my understanding so far.

 

out of curiosity, why an re instead of just an s4 or s5 turbo motor? both of those are plenty capable of 400+ whp

 

just thought the RE had some more low end... and i thought the internals were stronger(seals springs) but i might be wrong about that.
I guess after porting the s4 or s5 it will have the same low end benefits of the RE

i also like the having a JDM engine lol

 

here's what i recommend to guys that have me do cosmo swaps for them:

if you've got an n/a that you're going to turbo, go for it. a cosmo is only a few hundred bucks more than doing the same setup with a t2 engine, so why not?

but if you've got a turbo already, might as well get a big turbo, ems, fuel system, etc etc etc... max all that crap out, and THEN, toss a cosmo in there and enjoy the benefits.

and cosmos have more low end...eh, not when you stick a t72 with a q-trim on them... a cosmo with some bnr stage 3's would dominate the low end as far as 2-rotors go, though.

so figure out exactly what you want, make a budget and gameplan, and go from there.

 

I thoguht all cosmo's were turbocharged....

 

thanks for help with this... yeah i have a na FC right now. the motor has been blown for a while. i have already rebuilt it once to stock afew years ago.

so with the NA i guess you would suggest going with the cosmo right? I am going to stay with 2 rotors def. But i am still a little unclear whether or not i can build the engine or have to buy it used and go single.

Anyone have any insight on the cosmo wirring.. i think i want to go with a haltech or aem to for EM. can i use the same wirring harness out of a fc turbo?

 

well the exhaust ports are so restrictive in the stock cosmo motor you'd probably make more power with a stock t2 motor, so i'd say definately rebuild it.

screw the fc harness. it's old and crusty. haltech e8 is what i use in my own car, and have installed a bunch of them in other cars. reliable, simple, etc...

how much are you planning on spending on this?

 

yeah as of right now this is just a pipe dream for me i am just trying to get as much info as possible.. i plan on doing nearly all the work myself besides tuning and any kind of porting i decide on.

I like the low end potential of the cosmo.. if i get the exaust ports ported on the RE will it be a better performer than a T2? Other wise i will just go with t2 motor.

I plan on taking my time with the project, im in no hurry to get it done. I can see myself spending between 5-7K. is that reasonable?

thanks again!

 

5-7k is a little light for a project like this, but i guess it depends on what turbo setup you go with.

for that price range, i'd stay with the stock twins, or maybe try to find a set of fd twins for cheap. run them sequential or the low end benefits of the cosmo will be negated.

all said and done, if you had the bottomless budget, i thing a t4 gt35r with a .82 hot side would be killer for around 340-360 whp. spoolup would be super fast, without worrying about the transition, more linear power, etc...

or the bnr stage 3 fd turbos. either/or should do the cosmo justice.


~1500 motor
~1500 ems
~600 clutch and flywheel
~200 mounts
~500 intercooler setup
~1k exhaust
~1k misc. parts
~600 fuel system

all that is ballpark and guestimations, but you can get an idea of the financial magnitude of a pj like this.

 

great info, cant tell you how much i appreciate it.
After giving it some thought what i think would be good for now would be to get the RE with the stock twins, or FD twins if cost feasable. Then in the future go single. Does the RE twin setup have the "rats nest"? that was something i was trying to avoid dealing with but i might have to...
How would i best prep the engine for going single in the future so i dont have to rip it apart again later on (porting)?
When installing the cosmo i plan on handling fuel and EM so then when i am ready to go single hopefully it wont be too bad.

what you think?

 

RE rotors are more weight than REW ~ 20 g, other front counterweight, other intake manifold and throttle

 

U don't need port RE exaust
just put T2 sleavers instead RE sleavers

 

I didnt know they were interchangable...
I have taken apart one rotary but i didnt take the exaust sleeves out. how are they held in the housing?

also, are the rew sleeves any different than those in the tII engines?
thanks for the input...

 

and then port them. i think the cosmo ports open a tad later, but i'd have to check them to make sure.

 

I've been here and done that. T04S w/ bre w/brew housings, port matched, Wolf 3D. LOVE IT! The universal racer - good at road, drag, and autocross. (Can anyone say One Lap? I can - within 10 years I will do it). Going to turn car into dedicated track since the police and I have determined that it is no longer suitable for the street (at least, that's how I interpret them explaining how they would impound my car and take me to jail if they saw it again without a referee ruling .... ) It's all good - I needed the excuse to pursue my dream. Every man should have a dedicated race car once in his life....

I've got a pic of the engine bay around here somewhere......search on my name....

U need "red-hot" 3mm screw and screwdriver
Cosmo sleavers are smaller than T2


sleaver helds with 2 holders

I port exhaust approx 5mm from top
On this picture I put T2 sleavers into 13B-RE housing
