This is my first Rotary and need help locating parts for this engine. Attached are pictures of pieces to my puzzle which was handed to me.

The First Picture Shows a Distrubuter style hole with a gear offset inside for a distrubutor or pump, Im not sure what goes in there. And behind it is a threaded hole that looks like a section of the oil flow?

The Next pic shows a small hole about 1/2" that appears to be some kind of exhaust port? It is on the Passenger side lower rear of block.

The Next shows the passenger side of the front cover with a notched drive somewhat similiar to a distributor going into a cam on an OHC engine?

The Next shows the oil filter housing but in front of it is a tube that appears to be the oil fill tube but it has residue of exhaust in it?

The Next shows a sensor of some sort like and oil temp sensor?

I know that this is a lot to ask but I am really having a hard time finding information on this engine, especially one that has been previously worked on. Please any information would be greatly appreciated or a direction.

 

These are the other two pic's that I am having trouble with, I am not sure what goes here or its function's.

Any information on this please

 

is it me or that first pic says your engine is a 13b ?_?

 

The 20b has been modified with 13b Rotors.

 

Those are not 13B rotors, they're 13B rotor HOUSINGS. Dude, is this really a serious post or are you pulling our legs with a joke? If it's serious, STOP NOW, do not pass go, and immediately take the engine to someone who know what the hell is going on. The 20B is not your normal rotary engine and you'll certainly *uck it up, causing you much pain in the wallet.

You are in PA right? Take the engine to Dave at KDR. He's an expert.

 

1 distributor or crank angle sensor (CAS) hole and turbo oil send fitting.
2 turbo oil return hole
3 meetering oil pump drive
4 oil filler tube. Just clean it up and get yourself the upper section.
5 oil level sensor on the pan (not necessary to fix)
6 heater core fitting
7 oil cooler send to oil cooler (you need a fitting to match your oil cooler lines)

Do us a favor and list your project details, whether your going turbo or NA, and please stop using apostrophies incorrectly. It really bugs me. If you can do all that, I/we can recommend what to do with the objects pictured. Perhaps even suggest other places to look for additional gotchas (water temp, oil pressure etc). OK?

I am currently working on getting and electric waterpump because the lower intake is lowered and lack of room available for the original. I am working on finishing the exhaust, fuel and pretty much everything else.

I want to thank you for responding nicely, I appreciate it.

AS FOR DAVID HAYES, I did nothing to you and just because this is my first rotary doesnt mean I am a ****** idiot. It doesnt mean I am a genius either, so If you can get past the fact that I mixed one word ( rotor with rotor housing) then please give me feedback, if you can't keep your thoughts to yourself. I posted here because I am very confident and have over ten years experience (not with rotary's). Don't just assume failure on someone without knowing who you are talking to.

I am not going to take it anywhere until it needs tuned.

 

1) You have never worked on a rotary before
2) You don't know a rotor from a housing
3) You posted a bunch of pics asking what "goes here" indicating a big lack of knowledge

CONCLUSION = take the engine to someone who knows what is going on. The 3 rotor engine IS NOT the engine to take on as your first rotary project. It's also quite pricey if/when you make mistakes. 20B parts are hard to come by and cost a lot of money. Rotaries are different and in general, more finicky than piston engines so knowledge really does go a long way to success.

Are you going to rebuild the engine before installing it? If so, it's not a simple task doing this. Is your current engine ported so you can make power with that "G42" (read GT42R) turbo you'll use? Do you have a manifold (it will need to be custom) or a subframe to drop the 20B into the RX8? The list goes on and on.

Take it from me, the guy with a 4 year 20B conversion project. It's not simple and you'll save yourself a lot of headache and money by involving someone that knows 20Bs.

 

Everything is already installed I just have to finish it, and in my last post I stated what was done but you did not read it obviously. Dont tell me I dont know a rotor from a housing I just stated it wrong so back off that. I am not going to take 4 years because I will be dedicated. If I dont know the answer I will find it before continuing "Thats why I am here"

I dont care if its a lawnmower engine or a Mac truck, this is what I am working on currently and your making this bulletin posting very difficult. So be more helpful or **** off.

Anyways, I found a parts list on the 20b at www.tripod.com/rotary/images and am having a hard time finding the parts on the lists. I went to mazdaspeed, mazdatrix and a few others and havent been able to match the parts numbers with the parts. Any suggestions.

 

Given your attitude, I'll just **** off as you say. Good luck with finding the parts and with your project.

 

No ****?

 

david, it's my car. seekford's a friend of mine who's helping me finish it. we went to school together and our car history go way back when we started with b18 block on an EK all the way to a daily driven 400whp FD which he just sold awhile ago.

as for your concern, the engine has already been built. i know your saga wasn't quite what you had expected in the beginning, but frankly, this really isn't a rocket science either. since 20b is already built, we're approaching it like connecting/dressing up any other engine. we just need to find out what goes where and stuff like that. and like he said, we're leaving the tuning to the pros. i'm actually planning to have the engine builder fly up for the final tune.

and my friend's new to the forums, so give him a few days to get acquainted and learn how to maneuver the forums, eh? :P

as for yours david, how is it coming along?

 

I have to agree with David Hayes...
The beginning of this thread got me saying: "WTF!"
It's not even 20B specific.
Almost any 13B will almost have the same specs.
This is not about cutting the OP some slack; this is about basic knowledge - this isn't some newbie section.
Anyone seriously wanting to do a 20B either has to have a lot of money they are willing to spend or a lot of knowledge, period.
If you are going to ask basic questions like these, expect some heat, period.

I haven't been regularly coming in here cause I was wasting too much time on here previously.
I can't believe the crap that's being discussed in here - I just shake my head.
It used to be a pretty elite and serious group of people who would post in here, but I see too much dumbshit threads now.
WTF.

My suggestion to you guys is to read more and ask less questions.
This is how you learn and not look so dumb.

BTW, working on Hondas has nothing to do with 20B's.
If you guys "built" a 400hp FD, why the **** are you asking stupid question like this?
I'm sure you've seen all those particular parts of the engine (or something similar to that) working on that 400hp FD, RIGHT?

(back to lurk)

never said built. he bought one used, did some minor stuff to it, nothing near the actual engine block.

anyway, i'm still waiting for some original oem parts to come in from the shop i originally paid more than the actual going rate to do the entire conversion. they never finished it, and after some 20months of spending the weekends pissed off at the lack of progress, i just towed the car back. once we have all the parts we need, we will start then.

please consider this thread closed for now. we're still learning/reading. thanks.

 

we're all teachers and students here, however, I too am sided with DH and Ted.

 

You paid a shop over $35,000 for a conversion and still had nothing after 20 months? I hope you got a refund. With that kind of cash, they should pay you interest too.

 

All the parts you need come off a regular 13B. I'd suggest, at a minimum, getting hold of a service manual or parts manual...this is super basic stuff. Even more at a minimum, go look at someone elses FC RX7 and you can figure it out quite easily.

If you can't figure it out easily, do what everyone else is suggesting and take it to someone who knows a rotary engine; it will be a piece of cake for them.

 

Thanks, I realized that the questions I asked were stupid and plan to only ask questions if I really need to. I have many of the parts that were missing from the original rx8 and a bunch of parts that were ordered that will be picked up tomorrow. I will post my progress and hopefully more people like you post again.

 

I'm pretty close to pittsburgh, buy my gas and beer and i'll come spend an afternoon helping you figure it all out.

 

if I were u I would take PATMAN up on his offer, I would of took him to a steak & lobster dinner if he came over to help me out

 

be a lot of $$ for gas all the way to LA, especially if i drove the 7..lol
