13b-RE 13b-REW
 

what car does the 13b-RE come out of and what is the horsepower
what car does the 13b-REW come out of and what is the horsepower
whats the difference between the two which is better to swap in an 88 10AE

13b-re came out of the jc(?) cosmos, and it produced 230hp

13b-rew came out of the 3rd gen rx7's, and it produced 255hp us spec.

The 13b-re has lager intake ports while the rew has larger exhaust. The rew used larger twins stock. Supposibly the RE intake manifold will flow more than the REW. The REW used a larger throttle body. RE came with 3 window main bearrings, im not sure about the REW. RE and REW run 9.0:1 compression.

The REW is very hard to swap into the FC3s chassis. There are a few people who have done it.

While to swap the RE in all you need is a set of mounts which K2RD sells for $250. You will also need a way to controle ie. a haltech or microtehc or stand alone of some sort. There is stuff im forgeting.

Im in the process of doin a RE swap into an 87 TII. So far it hasent been to bad.

whats the cosmo exactly?

it was a luxury car produce by mazda. More info can be seen here http://www.dmrh.com.au/

thank you thats what i thought but just wanted to double check
i am going to be doing the same swap as you into my 10AE i was told by droping
a 13b-re into it with wolf engine management
a front mount intercooler stock twins non-sequential 1200cc secondary injectors
supra twin turbo fuel pump a 2 channel igniter full intake and exhaust with all other stuff like radiator and fan and clutch and flywheel etc...... i was told i could get 475whp at 14psi but everything i have seen or read i dont know how it can be done what are you expecting from yours

When im all done i want some where between 380 to 400 rwhp.


To get 475hp @ 14psi you are going to need a huge turbo. Something that wont have the best response in the wolrd. Look in the single turbo forum for more info about turbosizing, response, hp capabilities, and other things related. No matter how much i would like to tell you im a turbo guru, my knowledge of the subject is microscopic compared to some of the guys on this board.

Any other questions i can answer for you pm me or hit me up on AIM

You are going to need more fuel if that is the hp range you are looking for. Either add another pump or find one bigger. Other than that you look to be on the right track. Turbo wise theres a wide range you can choose from, me personally Im going with a Precision unit, not sure yet as to what size but its either going to be the PT67 or PT72. Just need to decide if I want a sprinter or a top end beast.....:D

well i was told he could do this with stock turbos and thats what wierded me out cause i heard the stocks are good for about 400 and thats it but he swears he could do it with no prob so i am not sure whether to go for it or not
the last thing i want is to have him do it and only get 400 instead of 475

To make those #s on the stock twins will be pushing it. You'll have those twins going close if not beyond thier limits. 400hp should be attainable as there are guys on this forum that has done it on the REW twins.

stock twins from the cosmo and trying to reach 475 rwhp? Not going to happen. The cosmo turbos have smaller housings than the FD twins and are even more limited in their upper psi and ultimately hp range. If the best output on an FD with modified twins was around 415rwhp at 17psi. Whoever told you that is bullshitting you into thinking they know what they are talking about and if you do let them do the work, know up front you'll get around 375 roughly at 14psi.

Tim

thats what i thought but chris from checkpoint well used to be from there said that and from everything i have seen it seems impossible

Be ready for a let down since you will not make more than 360 ish on stock cosmo turbos at 14 psi. Pushing 17 psi you might make 375 to 390 since it sounds like it's going to be a stock engine and turbos. You should ask Chris where he's getting that from and think about another shop to work with since he's BS'ing you from the start.

Tim

well the only mod internally would be extremely large ports (so he says) and all fuel spark and air needed with eng. management but still stock turbos and only 14psi
it still didnt sound right though

My friend, take a look around, in my opinion there isnt a car with that much HP on stock twins, further more, for those numbers at such a low boost level is unrealistic due to a couple of facts: 1. Stock twins are WAY too small, 2. a stock unported motor wont flow enough to make those numbers at 14psi, 3. if you do get a porting job, a nicely combined single turbo, race gas, and a well tuned ECU the more likely outcome will be arround 450@18psi. But again, that depends on your needs/goals for the car.

That's my 2 cents.

On pump fuel and 22psi, the above setup made just on 500hp at the wheels.

Hey AJC13B,

Can you share the details of your build? looks nice. Is that a regular floating bearing turbo or BB?

What kind of engine mods (ie. porting, 3mm seals, etc.) did you do?

What engine management you got on there?

Later,

The turbo is a non BB TA45 with 68mm compressor blade, 68mm exhaust wheel and in that pic a 1.22 housing. I later went to a 1.05 housing and made 570hp on C16 and 26psi. In my 1st gen it ran 10.32 in 2002.

Engine had standard inlet ports, just cleaned up. Exhaust ports had been swapped out and was using T2 ones. Rotors were FD rotors and seals in the 10.3 engine were 3mm HME. Injectors were 850cc primaries and 1650cc seconadries. ECU was an E6K tuned by HITman

Oh! thats-a nice-a!

I have an RE, I used the stock Turbo II ecu til I saved up enough money and went stand alone. Stock Ports T62 at 15psi put down 43X rwhp, now the motor is rebuilt, ported, and has a GT4088 boosting about 2 bar on race gas, but power is not maximized because it's running super rich. We're looking to take it on the dyno whenever I get a chance, but since school just started it seems like that won't be for a couple of months now. I'd go with the RE, it's a better motor just put some REW exhaust Sleeves and you're good to port and decent size single (T04S or bigger), with good tuning look for 450 rwhp plus.

Alex

what size is that turbo
i am definitley doing a turbo upgrade now
just wondering what would be a good size for 500-550 whp

oops i didnt read the rest of this sorry

I'd say go with a GT72 dual ceramic BB from innovative with a .94 a/r to 1.06 a/r tan rear if you have the money. If not you could just get the same turbo I got for 900 bucks GT40 .94 a/r but make sure it's the 88mm one or you could just go and get a T76 q trim with a .94 a/r. There are soo many turbo's out there you can pick from but you should have a basic idea to run with.

Best of luck,
Alex

uhhm, i thought cosmos came with a 20B? :S or is that just some of them? :S

Cosmos cars from 89-93 came with either a 13B-TT (first verson of the REW) and the 20B.

13B had 230hp and the 20b had 255hp. But obviously the 20B would net ooddles of more torque than the 13b.

I have just bought a 13B Re motor from UK and took it apart today for inspection. I found out that there was no 3-window bearings compared to REW which has! The intermidiate plate has the same primary port times as 20B (smaller than REW) but the secondarys has the same port timing. The exhaust has same port timing as REW but ugly 20B steel sleeves. I have decided to build Swedens first true 600 flywheel hp 13B, becausse nobody has ever make even 500 hp on a dyno. Hopefully i have it on the dyno this winter.
