New to Rotaries (VW with rotary inside)
I'm Andrew, I've been into VW's and cars in general for years, but never knew much about rotary engines. I recently picked up a '66 bug that has had a 13b stuffed in it years back, though; so here I am. It hasn't been driven in nearly 10 years, but we have had it running long enough to know that the carb needs replacing. So I'm going to do that and give it a full tune up at the same time. The first question I have is what the hell do I have? The bug I know like the back of my hand; but the 13b, I don't have the first clue about... :hahaha: I've been doing a bunch of reading up on Rotaries, but I can't seem to find what year would this have come out of?

Thats really pretty neat. I hope you are premixing two stroke oil with your fuel though, as it does not look as though there is any operating oil metering pump.

i would guess 76-78 yr model engine.

Considered doing this myself. Very nice.
|
That is pretty slick
|
bugs with rotors are nasty
|
nice bug you got
|
First civics and VW bugs boy what next ? I must say though that looks really cool, welcome.
|
cool car!

Wow that brings back memories. I had a 13b in a 1973 chop top bug. You have a potential street monster. The engine is an old 4 port 13b. The intake is set up for a webber 48ida. The adapter plate to mate the engine to the tranny is probably made by Kennedy engineering along with the special flywheel. The starter should be from a 6 volt bug because the 12 volt wont spin the engine fast enough. Cooling was the big problem with mine, which I eventually solved by running copper tubing through the heater ducts on the side of the floor pans. I ran a chevy radiator to the front of the car and made cooling ducts through the fiberglass front end. Good luck with the car. If I can be of any help let me know.

I forgot to add about the carburetor. If it is a Webber 48ida you might want to try to rebuild it as they are very expensive carbs. Some of the vw conversions ran a custom Webber 48 that was bored to a 51mm, you may have that carb. And I agree about the oil premix, you will definitely have to add oil to your gas tank.

im a local rotorhead if you need someone to come take a look at it. send me a pm
|
I've been working on a very similar swap myself. I'd love to see some pictures of how your exhaust is routed.
|
that the motor is a 13b from what looks to be a s4 rx-7 that has been converted to carberation and a 12a dizzy.. idk just what it looks to me...
|
That is a very cool application. Keep us posted on your progress with the car.
|
very nice vw, im a watercooled guy myself (mk2)
and have owned 9 first gens in my short driving career. |
hey mate, looks to be an RX4 type block.
|
Here is a friends ROTORBUG in the UK - running a 13b bridge port, 48 IDA webber and close ratio VW box..

Fixableunknown is right, 4 port 13b. 84 was the first year for a 13b in an rx"7", though not the first for 13b use in a mazda.
Nice ride. My wife has been talking about building one. I say only if she goes with a big single turbo. |
13b came out...

Yep, it is running pre-mix only. That's one thing that the guy I bought the car from did tell me about before he sold it to me. :)
When did they start making the 13b? I thought I read that '84 was the first year for it? Im pretty sure it the 13b came out with the rx3. she is a chunky rx2 ;) <3 |
That looks like a Racing Beat manifold. We tried a blow through turbo setup with one of those. It worked but hard to tune and even harder on the vw tranny.
|
Took me a bit to get back to this, sorry about that. I had a really busy week last week. The manifold is an IDA manifold. It actually had a 48 IDM (predecessor to the IDA) on it when I bought it that I just sold on eBay. I'm going to buy a new IDA to go on it to replace the IDM. As for the engine, it's not looking too good at the moment... :sad: I posted this thread about it as I started doing a little bit of maintenance.
