You really need to do more research on the subject matter.
It sounds like you're being mislead...

Any chance u can tell me the name of the thread comparing S and Bridgeport for NA 13b I would like to learn the "proper" information behind the porting.

Jr_gosetto · 09-18-2013, 03:57 PM

And I'm just elaborating on my previous post about the NA with a Bridgeport. I'm not saying these is no aim to be had from a Bridgeported NA 13b. But from what I have heard the gain in power isn't worth the trade off in reliability/maintainence. I have heard guys running Bridgeported rx7's have to change the spark plugs about every 3 weeks, oil changes much more frequently, and it makes the milage much worse. Plus the same guys say it dosnt have neer as much low end. Also like I said I a previous post (give it a quick look over its #13) anyone know about high compression turbo setup.

Turboing a Renesis engine, especially with 10:1 compression is a really bad idea. The Renesis is not designed for and not strong enough for it. Detonation is as much, if not more, of a killer for rotarys as it is for piston engines. The only way it can be done safely is with massive amounts of water/meth injection and a high end ECU with an incredibly good tune. If you're putting that kind of money in it anyway, going with an REW and the ECU would make more sense. That is not easy either as there are compatibility issues with the 8s electronics.

I'm not a fan of doing much port work on anything, but the NA will benefit from it more than the turbo will. The turbo can overcome combustion filling problems with boost and changing the port timing has the same effects, as what you stated you don't like, on both of them. Check out some of RiceRacing's posts on this as well as others. You may get some gains, but there are tradeoffs. Whether or not to do porting really depends on what you're trying to accomplish.

Rotary Evolution · 09-18-2013, 05:14 PM

the issue with the renesis and turboing it is the side port exhaust. even n/a the engine has a difficult time cooling off the side seals before the next combustion event takes place. now add in a turbo to the mix and the EGTs are a chunk higher, beyond the comfort level for the side seals, warping them and eventually ejecting them as the early engines would an apex seal(except with the renesis, literally almost everything gets damaged including the irons).

now modify an early peripheral exhaust rotor housing to work with the renesis and think about what happens.

the increased compression ratio is now what is going to limit your possible boost level, but at least the side seals might just survive.

i'm currently working on a 5 port turbo renesis exhaust manifold... if you plan on doing more than stomping the gas pedal more than once every 15 minutes it's going to take hybridization or a complete engine swap.

Ok so turbo is a big no no thanks for the info guys. Sound s like I might go back to my old idea of swapping in an engine from a 93 rx7 and making it 4 rotor. And before anyone thinks im crazy look at this link http://rotaryengine.com/services/34kits.htm they do the work I get the engine I just have to make it work in the 8

There are parallel install options from Adaptronic and Haltech offering standalone control of fuel and spark as well as advanced options such as launch control, boost control, etc. PM me if interested.

You will not extend the rev range by adding a turbo. Doesn't work like that.

No.
I think you are crazy.

realistically, what is your budget for making this 4 rotor? there's a reason there are more 3 rotors running around than 4 rotors. Not picking on you, I just want to shine the light of reasoning as it's significantly more than most people think. However, if you know how much it's going to be, carry on and keep us posted. We all love a 4 rotor project

a turbo and renesis can work together without all the other BS but there are steps you have to take and it also depends on what you plan on doing with the car. if you plan on pushing 10+psi and run pump gas while tracking the car, no. alcohol, except not everyone has E85 available to them locally. water injection, but i wouldn't rely on that to keep EGTs down indefinitely to save the side seals. engine swap, probably the most common route. hybridization, probably the least common route.

Really I was jut askin honest questions I wasn't trying to make it sound like I know everything. I was trying to get good info about this and u were being very undesisive, little info given just bashing me pretty much so ya I will defend myself. And wat r u really going to do beat me up lmfao I'd like to see that

Technically your the ignorant one.. You are the one with no knowledge of anything rotary. If you did you wouldn't have bought that slow whatever it is in the first place.

When someone says 4 rotor they are talking out if their ass you have nowhere near the budget and knowledge to get it done. You also have a shit attitude that is going to make the few people who might be able to help you achieve anything with your slow 8 besides blowing it up. Sit back and watch you fail.

Now go blow your shart up like the rest so other people can buy your roller for cheap and do something but fanboi in it.

Oh and I bench 320 blah and bleh breh! So breh come at me breh .

GDHSF!

Fuck Off I'm out!!
