13B Turbo w/duel Weber's
 
I happen to have a 13b S5 turbo sitting in my garage and it will they just sit there and rot unless i do something with it and i don't want to go through the hassle of finding a S5 Turbo 2 to put the motor in.

I've been searching around the net for some information, but it doesn't seem like a lot of people have done this.
My buddy has a 69 VW bug with 13b mounting brackets and duel 44mm weber's that are set up for blow-through. we were planning on stripping the electrical off the engine and making mounting plate for the carbs. I know that i wouldn't be able to keep the coils, but i have heard you can take a 12a distributor and put it on the 13b for direct fire.

has anyone done this and able to give me some pointers and other problems i may run into. we aren't expecting a crazy amount of power just enough to get the 1200lb car down the track.

i know putting a rotary into a Beetle has been done enough times, but i don't know how many people on the board have done it. off the top of my head, i think Jeff20B and RxBeetle have done it so you can try searching with their usernames to get more specific info or maybe PM some specific questions to them. also, if you poke around the Other Rotary section, you may get more useful responses.

I know they can be put into beetles, my question was can i just strip the motors electrical and put a carburetor on and call it good? or do i got to do some other things to it?

actually, truth be told, you made a statement about the stripping the electricals and using a carburetor - not a question. how was i (or anyone else) supposed to know that this was the crux of your post?

anyway, the simple answer is yes. strip the motor down to the bare shortblock. use a Gen I distributor and wire up the ignition to use either aftermarket coils or Gen II coils. search for DLIDFIS in the Gen I section there are ample threads and a few newer tweaks to Jeff20B's original idea.

also on a s5 motor dont you have to get a different omp if your going to run it? i thought the s5 omp was controlled by the ecu.

diabolical1 12-23-08 08:55 AM

it is controlled by the ECU, but it would make the most sense to premix in the application he's proposing.

you'll need to plug the injector holes on the housings, and plug the OMP pump on the front cover, and on the housings as well.

find a way to re-route the oil cooler to get airflow; on either side of the chassis through vents cut on the fenders, or below the engine with some way of routing air to it.

you'll need to find a way to fab up a cooling system so the rad can get airflow.

its a little more complicated putting a 13B turbo than a 12a in a Bettle than just getting the adapter flange for the transmission, and engine mounts, and simple cooling system fabbing and a carb setup.

Turbo rotaries run hotter than n/a, so you'll need to figure out of way of cooling it down enough that you toast it due to thermal breakdown of the oil and/or overheating of the engine

i've seen it done before and its a very unique swap, the fabbing up is quite simple really on the few i've seen in person. just a few vents/holes cut, and some way of ducting air to the oil cooler and rad.
One really unique way i've seen at a car show in Florida was that the gentleman used aftermarket wider fenders, had big vents cut into it; one side was for the rad, the other side was for the Mocal oil cooler and I/C, all with proper ducting. Very trick, lots of AN fittings and stainless lines, looked very clean, this one used a carbed 12a-T with MSD ignition.
IIRC it made around 210hp at 12psi, cant recall the size turbo though, it looked similar to the size of a S4/S5 turbo

why would it be such a bad idea to dun a s4 omp vs premixing?

ive seen a rotary vw, with the rad in the front of the car, allso it had what you could call a top mount inter cooler. there was a metal plate between the motor and ic, and on the side of the beetle it had scoops to duct air in ect. i swear the ducts where knock off for a 67 shelby.

iam preety sure ive seen the body kit you talked about.

didn't mean to imply that it's a bad idea. it's not. i just meant it's the simplest way to insure seal lubrication without having to swap OMPs or rigging up some way to use the one he has. in the end all that matters is that the seals get regular and reliable lubrication.

Do you have the transaxle to engine adapter / flywheel? I have : Kennedy adapter, flywheel, and a complete racing beat exhaust fabbed up for a 13B swap into a VW bug. I might even have the clutch?

Are you interested in purchasing? If so, let me know and I'll send pics. Send a PM. I'm located in Southern CA, Orange county. Available for pick up or I'll ship if you want to do paypal.

stupid stupid question, when you say duel Weber's are you talking about the normale 2 barrel webber carbs or are you talking about the rare intake manifolds for rotarys that uses 2 2 barrel webber carbs?

post pics of your intake and carbs been trying to collect pictures ect.
