RX-8 3 Rotor from Mazmart
Saving in progress. 
Just curious why'd you guys go with the 20B as opposed to the 13B REW, which seems to be a more common swap option.
More than likely easier to find, parts are easier and cheaper to source and can make roughlythe same 400whp with a decent size single turbo and some porting on the REW.
Either way its nice to see another viable swap option/kit for the 8. Looks like I'll be holding onto my 8 for a long time with all the new resources and info out here, if I ever decide to ditch the renesis.

The main thing that would make someone choose this route though has nothing really to do with numbers. Peak power vs peak power doesn't explain anything else. The feel of the two engines would be dramatically different, they would have very different torque and power curves, they would drive very differently, they would sound different, etc...
I would bet that in the end most people that would choose an N/A 20b would do so for these reasons, and not 'cheapest route to X peak power'. It's why I would. Most peak power number guys don't seem to understand that concept though.

latest 20b n/a motor I saw made 312whp 240tq with stock intake manifold and streetport. reliable good power right there... that's what I want for the track. it made over 200tg from 4500rpm to 9krpm. the smooth power band is what I'm after. 20b ftw

It's certainly more common, but mostly due to price.

But the benefits don't end there. Think about how much SPACE there will be in the engine bay since you won't need intercooler piping. It will be neat and tidy under the hood. Additionally, with the removal of all the turbo and manifold, it should lead to cooler under hood temps when doing prolonged tracking.
And that sound......Hnngngggggg
Sounds pretty solid, the 3 rotor is a dream engine to me up there with the 13b rew. Sounds like a good way to increase the value in the rx8 market as well, introducing a kit like this. The prices on 8s have dropped significantly for a Series 1.
Attracting loads of uninformed buyers/"car enthusiasts". I could see more people with a bigger budget buying a roller specifically for this swap. And hopefully we will see more 20b 8s around.

Hi Paul, thanks for the response. When you say "Full job done HERE is in excess of $20k"....does that mean, swap performed by Mazmart on site? AKA, customer sends you a car and labor is done by Mazmart? Sorry for the dumb questions but I'm not familiar with y'alls business yet.
I guess what I'm asking is will this kit be something a buyer purchases and then does themselves or will this kit be something installed and tuned by Mazmart.
Yeah I figured it was borderline for a 20B making healthy power but KNEW the AZ6speed would die an instantaneous death haha.

.......now I'm REALLY interested! Part of the barrier to entry for some of us is that there's no guidebook to anything like this. Offering a turnkey solution for those that want a swap of this nature would be cool. 
I think both options would be nice. A turn-key solution for some, and a homebrew "kit" for others. But we will see what happens.

Paul knows and does lots more than one could think... 
Paul I sent you an email about my opinion on that.
But I think everyone won't loose the weight distribution ad drivability (I think bump steering might be a concern).
Maybe will be fine to know if an upgrade of the braking system is needed.
Bye
P.S. In my opinion 400hp is the minimum for the bucks.
