Ok here's the deal guys...

i dont have much experience with 3 rotor's so im asking for adwise... i have saved up alot of money and are now considering doing something to my 8 other than looks ..

Maybe a 3 Rotor swap.. i been looking around but stuff like 20b and 13b get's me confused, also theres stuff not being answered anywhere...

Two simple question's :

1. What do i need? : Can i just get a 3 rotor and put it in and go ? or do i need other stuff like gearbox new shaff's all the way to the rear wheels and stuff?

2. Is this even doable on a everyday car? : Yeah im using the car every day to work and other every day stuff ? how's the 3 rotor gonna handle that? is it posible?

Also just some advise in general about this is very apriciated ...

Here is one thread to start looking at
https://www.rx8club.com/series-i-major-horsepower-upgrades-93/project-20b-rx-8-commencing-186226/.

The 20B swap is a simple thing, you should see if anyone else by you has done this.

You will need the engine gone over. If you want to get a good amount of 20B info spend time on the RX7 forum in the 20B section. It isn't just a drop in and go thing.

1) No you'll need to address numerous things if you don't want issues, some very expensive.

2)Yes if you do it right the first time. We've done numerous 20B swaps and it can be done but it's not drop in and go.

The best advice is find someone who has 20B experience. Just because someone has built a 13B doesn't necessarily mean they have experience building 20B's.

That was seven questions, not two.

Thanks for the Info so far ! what's the diffrence betwen a 13b and a 20b ? and what does 20b stand for?

Money is not the problem. i just want to know what should i get besides the motor to get this right?

13b means 1.3L aka 2 rotor. 20b means 2.0L aka 3 rotor

Opane

Ahh ok i see .. So when someone is talking about doing a 13b swap in the Rx8 they meen putting in the motor from an Rx7 ???

expo 1 - Thanks alot for that link. how could i have missed that thread? lol.. nvm i read the intire thing now and it was i big amount of knowledge . awsome !

Technically, the renesis is a 13b. There are a few numbers or letters after 13b that signify which model they went in. 13b-msp is a renesis for example 13b-re or 13b-rew are different

Someone who has built and tuned more than one 20B. As well as has decent fabrication skills. Spend some time over here and read up on things. The level of knowledge on these engines is a bit more in depth over there.

Most likely any 20B that you pick up will get some sort of rebuild. Yes, it can be a daily driver and handle more power than a 13B motor if you decide to go FI. Remaining NA will go a long way with any motor but this option is up to you.

The 7 club is a great place to start to get a in depth understanding of what a 20B is but remember there are few members of the 8 club who have done this very swap/build so doing plenty of reading on your part will serve you well.

Good Luck

Find a place that will do the install and tuning before even considering this swap.
Unfortunately we were born in the wrong side of the world for this kind of swap, what's your budget anyway?
Anything below 25000€ will not lead to a complete and ideal swap for a daily driver, including labour.

Opane

Budget is really not a problem stop asking it hehe.. :P nvm i just want things to WORK .. and if the 20b swap is so complicated maybe i should go for a 13b ?? is that easy'er or?

They are asking about your budget because a project like this can be upwards of 40k usd. Yes, almost 4x the value of the car itself. There is ALOT of fabrication involved if you want it done right. If you are serious about this build you might want to find alittle more info on the engine itself. It's hard to take you seriously when you don't know the difference between a 20b and 13b. Why do you want a 20b in the 8 anyway? For 99% of 8 owners a 20b will be too much car to handle. Read up and goodluck to you if you are serious.

bse50

If a 20b swap is a hassle for your shop of choice it will be pretty much the same for a 13b rew or re swap. There will be less fabrication involved for sure but there would still be some crucial points to be addressed.

You should consider to just turbo your current engine in a good, reliable way. You would be satisfied anyway

13bre swap can be done for 15-17,000 euros.

Dude first of all you dont have to be a gear head to like fast cars.. neither do you have to be a gear head to be able to handle a fast cars.. its two diffrend things.. and second, i live in denmark cars are ALOT more expensive here.. a used rx8 is like 60k and a new one is above 100k mine was 112k usd . so i got money.. but since im not a gear head on rotary's my self i want the build to be as reliable as posible ... so thats why im asking in here before getting into something that will result in weekly or monthly rebuild's and problems ..

Turbo'ing the stock renesis engine is not gonna work for me.. the diffrence is not big enough.. if i wanna do something i wanna do it right ..

bse50

Double the stock power is not enough?

I'm surprised people are even answering this "nub" to begin with. If you got an unlimited budget then don't worry about it. Take your car to a shop and hand them a blank check... otherwise use the search function because all the info you need has already been talked about/discussed.

@!!narotordo

Put a 4 rotor in. Be the 1st 4 rotor rx8 street driven car everz lol

^ Good idea. 3 rotors might not be enough power for em anyways

Opane

Are you kiding me ? **** is your problem dude? ... this thread is a "WHAT SHOULD I DO" thread .. not a 3 rotor build thread.. could even be the 13b build ppl are talking about, 20b was just my sugestion but i dont know, wich is why i made this thread. i want the most reliable solution there is, i ofc dont have unlimited budget dont be stupid, but i deffinately have enough for this build.. but that doesnt mean it will be reliable? .. and that's why im asking you ppl about it? ... so please make a comment about it or shut the **** up, thank you..

bse50 - double the stock hp is just about what i want yeah but i dont think i will get that from the renesis engine? correct me if im wrong ?

I don't like quoting obama but.. yes we can!
You will end up with around 330\350whp with a properly built turbo kit, denmark is pretty cold so the temperatures should allow you to run with the proper timing all year round.
It's not really double the stock power but because of the intake and exhaust ports configuration it would be a very smooth power band with a high average power figure.
Many 13b rew with 400 or so hp suffer from very peaky powerbands that are pretty unusable.
