I want to take my 13 N/A stock engine out and drop a 13b TII cosmo engine in it... does anybody know were i can get the engine and how much its gonna be?

gingenhagen

you mean the cosmo 13b-rew (commonly called 13b-re) or the turbo2 13b. Either way this has been covered multiple times.

But just to start you off...

WHOA!

A 13B-REW is found in 3rd generation RX-7s, a 13B-RE is found in Cosmo Eunos, both are twin turbo and 13B, but after that, there are ALOT of differences (such as one bolts in with motor mounts and the other doesn't). I suggest you read the f3cspro.com website for more information.

13B-RE will bolt up to a 13BT (TurboII!) transmission yes.


Taken from Ted's site:

Transmission
The Cosmo 13B-RE bolts onto the stock FC transmission with no problem. The Cosmo 13B-RE only comes with an automatic transmission option, so it will most likely have a counterweight and flexplate attached; if your engine did not come with a counterweight, you can use a Kouki FC3S/FD3S stock flywheel or automatic counterweight. If you are going to use an aftermarket (lightened) flywheel, the automatic counterweight is required. The automatic transmission counterweight makes it easy to install an aftermarket (lightened) flywheel in this case. Be sure to install a new pilot bearing and pilot bearing seal before installing the clutch.
[Lightened flywheel - $400; ACT Heavy Duty clutch kit - $350]

What kind of car do you have in the first place? TII or NA?

Or just read this:

The "13B-RE" in the cosmo is called 13B-REW. It just happens to have 13B-RE stamped on the intake manifold.

You stated you want to remove your N/A motor and put a 13B-Re in it. I'm going to presume you have an NA car. The NA drivetrain isn't up to the task of what you most likely have in mind.

Thats a blatent lie.

gingenhagen

Hmm...that may be true. Let me go double-check my sources again and make sure.

edit: Ah, here we go.

W is for double (waberu?) turbo (twin turbo)
The cosmo 13B-REW has a twin turbo so it makes sense in my mind.

Whhhaaaaaatever.


They are two different motors, one just happens to have a W attached to it's name most of the time.

All the "W" symbolizes is the fact that the motors have two turbos. So he 13B-RE is still a "W" motor even if they don't stick the W on there. The blocks are different in many ways, namely the exhaust ports on the rotor housings. Anyone who has ever seen a 13B-RE housing will tell you. They have stupid little exhaust defuser dealies stuck in there whereas the REW housings do not. The REs have differences in the intake ports too.

Long story short, if you rebuilt a Cosmo 13B-RE with 13B-REW rotor housings, you'd be set for some power

They are very different motors in terms of buildup, no matter how many letters you stick on their name

gingenhagen

i would most certainly agree. The cosmo 13B-REW and the fd3s 13B-REW are indeed two different engines. And the cosmo 13B-RE (160hp n/a) and cosmo 13B-REW are two different engines as well.

Smoke crack often? How can you not understand even though it's been laid out so many times for you? Let me try. The twin turbo 13B-REW engine is found in the FD Rx-7 ONLY.

The 13B-RE is an entirely different engine which also happens to be twin turbo. This can be found in the JC Eunos Cosmo.

13B-REW = FD Rx-7

13B-RE = JC Cosmo

And there's no such thing as a n/a 13B-RE.

Yeah... was gonna say... N/A cosmo.... I must have missed something

gingenhagen

care to explain this then?

When I said "there's no such thing as a n/a 13B-RE" I meant there is no n/a version of the twin-turbo 13B-RE as found in the JC Cosmo (90-95). The engine in that thread is a very early (pre 1986) injected 13B and is an entirely different kettle of fish. Everything else I said still stands.

gingenhagen

You still fail to see the point I'm trying to make. 13B-RE is the name of the engine that I just showed. 13B-REW is the name of the engine that you are incorrectly calling "13B-RE". 13B-REW is also the name of the engine in the fd. That is because both engines have twin turbos, with the "W" standing for "double turbo". The 13B-RE does not have a W in its name because it does not have a twin turbo. Clear now?

How is this so difficult for everyone?

13B-REW is the designation given to all 13B Twin-Turbo motors in the FD.

The 13B-RE is the name of the motor from the JC Chassis.

So, they are different motors. With different names. They are both twin turbo (Yes, I know there are much older forms of the RE which were N/A) and jsut because it's twin turbo does not mean is HAS to have the W on the name of the motor. Why would any company that knows what it's doing name two different engines the same thing? For simplicities sake they left the W off of one of them, even though they are both twin turbo.

gingenhagen

haha. I would ask you the same thing.

It seems to me much more logical that they would give the twin turbo engine the twin turbo designation and the non-turbo engine the non-turbo designation. Of course, it seems no amount of evidence/arguing will make you change your mind, so whatever. Either way, everyone seems perfectly happy calling things the wrong thing; so if everyone else is wrong and i am right, then i guess i must be wrong. Haha, peace.
