Im probally going to take this deal,Im gettign a 87 wrecked car with a good title for $300.

Im getting parts ready for my friend on his 83 GSL,
Im thinking of using some of them parts,and hooking him up with this 6 port 13b,
We will be going carbed on it and I have some questions.

Since we will be going carbed (600 dbl pumper)
and road race header,(No ecu etc etc),Can I throw the actators out the window?

Now what would you do with the sleaves?

What sensors are on the block that I would have to rewire into the harness?

What other mods do I need to do besides:
SE oil pan
12A dizzy
12 FT cover

Can I use his GSL tranny with the 13B and the 13B flywheel?

Or Do I need to go to a 13b tranny?

Will I have to make a custom mount for the tranny?

Any info or PICS will be nice.

You can keep the 12A tranny. If you take out the auxilary ports, so people say the engine will run rough at idle/low speeds because the fuel requirements are low and the auxilary ports are open, allowing more fuel in than what is necessary. You can keep the sleeves in since they operate off of exhaust pressure. It take 3.5psi of exhaust pressure to move the actuators that open the ports. This happens somewhere around 3800rpms. If you are going with a after market header, you can remove the actuators. To get the ports out, you have to take off the intake manifold. Look in the 2nd Gen archive for write ups on how to do this.
If you are running a carb, then you may as well ditch the rats nest. 99% of the electronic **** on the 13B is emissions control for the fuel injection system. I say, dump gas, burn, go fast

actually, i don't know if the RB/Holley manifold has provisions for the 5/6 ports and actuators. so you've got me on that.

it will bolt up fine with you stock tranny.

from memory, the only issue i had with the Gen II 6-port, was that i had to get a block-off plate for the EGR-crap on the center housing. you will also have to find a way to plug the injector holes (but with a Holley, you should be able to just leave the injectors in them.)

Also, you could probably follow the thread at the top of the page about swapping a 12A for a TII and just ignore the turbo specific stuff and see what you would need for getting the 13B block to fit into a 1st gen.

Yeah, there was a company that did that for a while. Im pretty sure they were called Mazda. The engine was available in the GSL-SE .

I know what I need to put* it in a FB,


I want to know about getting rid of the 5-6 port
I dont care about emisions ****,cause we dont have inspections,I will be putting a 600 dbl pumper on it,RB intake/RB road race header<--for no 5-6 port

I will NOT be using the stock EFI intake cause its going to carb..I know I need the block off kit etc etc

I need to know CAN I take the sleaves out or just keep them in cause it will be going over to carb..That is my main concern..I know everthing I need for the swap,

Im glad I can use the 83 GSL tranny cause right now it has a 4 puck in it,I wanted to know what sensors are on the housing/if any that I would need to rewire in cause im going to carb I dont need the 13b harness..

SoRRoW

Does your parents know your up late post whoring on the net?

If you want to be a smart *** read the whole thread,
I said 87 6 port 13b swap not a GSLSE 13b...

I just rememberd your the guy who thought you ran 14s and never took your car to the track,

Manntis

Hey now, you did say 6-port 13B, which is what the SE has...

Play nice, evvyone

SoRRoW

I also said 87 6 port

Which is diffrent from a SE 6 port set up.
The SE I can use the front cover/oil pan etc..

87 I have to mod my self BUT the mods im concerned about are the 6 port POS sleaves/actuators.

BTW, I said 15 seconds, and only cause it seemed possible. My 0-60 was almost dead on, so I thought the 1/4 mile would be close too. Damn, some people are so touchy .

Has been done dozens of time. It will work if you know what to do. If you're going carb anyway, it's a really simple installation. RB motormountbrace GSL-SE oilpan, 12A front cover, and that's almost it. It'll bolt right up to the tranny, and electronics are useless if you go carby.

Rotor13B

6port is as 6port does.....lol

rotary emotions

Forget about that!!!
Not all sixport engines are the same. But as you'll probable use US spc engines, it won't matter that much.
If you go carb, it's very easy. But if you go EFI, then you better take a look at the donor first...

SoRRoW

Hell yeah if your "estimate "is faster than my actual time..lol

SoRRoW

Ok MY fault for not getting into details....

I KNOW you can put a 6 port in a SA/FB

You guys are not getting the question,
Im going CARB and KNOW I wont need the electronics/harness/ecu...

Imagine a bare block with the pulleys no emissions no a/c..no intake etc....


Put on a RB/holley intake
Now whats the best thing to do with the sleaves..since the actuators willbe gone..do I leave them in?take them out?

ASEmaster

Sorry I don't have any useful input for this thread, but I was wondering... what's the advantage of a carbed 13B over a standard 12A? I've toyed w/ the idea myself, but didn't know how big the payoff is.

rotary emotions

well, about 150cc's extra. Thats 10% more then a 12A.
If it's all really worth it, I don't know.
I'd swap with EFI, but I guess carbs are easier, and can make plenty of power too.

lotsacars

What's the facination with turning an EFI mill into a carbed one? Is it based solely on $?

SoRRoW

Cause im workin on a friends car and we have some new stuff like a 600 DP and Holley blue f pump to install in his 83 GSL and I will give him a engine and or tranny for $100.

Why stay FI?

It will cost more money to get more HP,

Right now we have these parts ready to go on,
All he needs to do is buy the injector plug kit,and 13b RB/Holley intake and sell his 12A one..

The rest of the stuff will swap over..with no problem,
Im just tring to figure out ths deal with the POS actuators and sleaves..

rotary emotions

Throw them out

okay ... so you're planning to run the 6-port with the 4-port Holley manifold, is that it?

well ... it's not an ideal situation for the motor, especially at high RPM. it's really hard to say what you should do because the split between 3-4-5-6 sits right in the middle of the secondaries on the Holley manifold. it's going to screw with your flow and port velocity.

i'd say take them out, it's probably better than leaving them in. but be prepapred for trouble with that engine if your friend has a heavy foot.

my concscience will not let me end this post without saying, in the NEAR future, either convince him to get the 6-port Holley manifold or pull the motor and convert it to 4-port (either with the appropriate plates or by siamesing the 6-port end housings.) it should be clear that the manifold is cheaper than a rebuild ...

other than that, like i said before ... the tranny will bolt up fine. all you need to is to block the injector holes and the EGR stuff. and since you're using the Holley manifold, you should be able to leave the stock injectors and the EGR-gadget in place (they'll just LOOK ugly )

hornbm

if I was doing my 13b swap with a carb, I would DEFINATELY go with a 4 port.

I'm sure it would much easier to install, and you can do more to it. (porting, etc)

SoRRoW

Yeah I was going to make a 4 port with 12A plates and SE housings,

BUT this engine is amost free,and we got the fuel pump,600 double pumper for it,We are just going to put the intake on and the road race header and try ti with out the sleaves,

Im glad some of you gusy were starting to understand what I was saying,I guess the others learned something too.

Ill keep you guys updated,If this dont work out,I guess Ill put it in my GS and give him my 12A with intake and header.

BigJim

Wiat, im pretty sure u can carb a 6 port, and sitll have the 5th adn 6th ports work. Doesnt racing beat or someone make a lower intake for a holley that keeps the 5th and 6th ports working.

Steve Shulz

Not sure of your budget sounds like a helluva deal but I agree with BigJim, more gas = more fast. Thats two more ports that are there just itching to be used. Good luck and keep us posted for sure.
