Thats the best info you can get=).

 

You can use a 4 port bridgeport template as a basis for a 6 port NA engine. The bridge ends up in the correct location and you then have the option to extend it. The more you extend it up and down, the higher in the powerband the engine will perform. NA 6 port bridges are going to end up as fairly high peak power engines (9,000 RPM) due to port size and location.

 

ok cool and i have another question...what do yall mean as 4 port/6 port and what would be my 13b n/a motor have?

 

Your 13B NA is a 6 port.

If you have to ask this, don't bridgeport the engine.

 

Dude what the **** is your problem all you do is contredict what i ask. I joined the "club" to try to learn more about a ****** rotary motor **** man why do you have to be a ********?

 

You're overreacting.

 

Ban.

See ya!

 

You don't know enough to know you don't know.

Think of it this way. Your question was a bit like asking "what aluminum alloy and heat treatment will I need if I cast my own pistons?". And then following it up with "Oh yeah, and what's an engine?".

You asked:
This indicates you want to bridgeport your engine. This also indicates that you are knowledgeable in porting and how to rebuild an engine (you do know it has to be disassembled to port it, right?). A certain level of knowledge is assumed from this post.

You then say:

Meaning that you are satisfied with the answer.

I then point out:

Suddenly, a wrench is thrown into your plans. You don't realize that you are asking for a very advanced form of porting that requires considerable effort to make work properly. I point out the difference between the port templates the vendors sell and what you need, probably saving you a major surprise when you stick that template onto your irons and wonder why things don't add up.

Then you ask:
This shows that you have absolutely no understanding on what you are asking for. 4 port vs. 6 port is one of the most basic questions that you could possibly ask, and one that would have been answered by even a tiny amount of research (it's amazing that the search feature will give you a crapload of info if you search "4 port or 6" or some equally generic phrase).

I then make the observation:

I often post in a very concise and direct way. It saves me a considerable amount of typing and generally does not open stuff for misinterpretation.

You then misinterpret what I meant as a hostile comment and post:

To which I will reply:

I don't have a problem at all. I was answering your questions as laid out by you. Far from contradicting your questions (how does one contradict a question anyway?) I was simply not giving you the answers you were hoping for. You are starting from an area of zero knowledge, which is fine. You have heard the word "bridgeport" and thought "Wow, that sounds cool!". Then decided you would bridgeport your engine. You asked for templates, with no indication that you do or do not have the knowledge to use them.

You need to walk before you can run. It is important that you learn the basics of an engine before you attempt radical modifications to it.

I think you would be interested to find out that bridgeporting the engine is rather easy. Takes about an hour with a die grinder/Dremel. However you've now built an engine that will not run in your car. In order to make it work properly you need a new intake manifold which is tuned for the high overlap ports. You will need a full exhaust upgrade with a set of long tube headers and flow through mufflers. It will be ungodly loud. You will need a full standalone EFI system and the tuning knowledge to make it work. Several hours on the dyno will be necessary to tune the car and a good amount of experience will be needed to road tune it for good driving manners. Regardless of how it is tuned, you will get 8-10 MPG in the city, and mileage in the low to mid 20s on the highway.

And suddenly, I'm not at all a "********". I'm the guy that just saved you thousands of dollars, hundreds of hours, and a failed project.

 

this is one of the best responses i have ever seen on the interweb

 

very fair response Aaron

the OP needs to control and respect themself

 

Amen

Nice post Aaron, hopefully the op can uderstand that, maybe a streetport or turbo should be his first...

 

good god ownage...I was going to somewhat side with the OP (sympathetically), but I don't think I can after that post

 

Street port is by far the easiest no brainer mod you can do. That's the route I went with never having rebuilt a motor in my life. Now I wish I'd have done more since I want more power from my N/A. Applaud the OP for at least asking questions and doing research. Something I didn't do at all before my motor build.

 

If you can be offended by that, you need to toughen up a bit before asking noobish questions on an internet forum. He stated the facts very clearly. There are indeed some people who would relish the idea of shooting down your hopes and dreams before you even see them fleshed out just to get a kick. Aaron isn't one of those folks.

Engine porting is not easy. I had a junk motor a while ago that I decided to practice on without a template and effectively trashed it even more, but Im better off for the experience. If you want to port your own engine, but have no idea what your working with, it's best to leave it to a professional.

 

To shay... Porting isn't that hard...

 

I think the OP is DAMN lucky that Aaron remained calm, explained himself clearly, and then didn't ban him for that attitude.

 

Yes, to the OP: for future reference, the name in red means ADMINISTRATOR
