*YO MANG I'm running 25psi on my T25* *Pshhhh f00 I'm running 15psi on my T86*
I don't know why people get all funny in the pants when boost number are involved. The number itself is USELESS without knowing what turbo it's on. That T25 on the Renny will do nothing and the 15psi through a T86 will send it back from whence it came. It's all about the CFM.
Point is, somehow, somewhere running 20, 30 ,40 psi became the "thing" when it came to how much performance you have and how much you can brag.
I also don't know when a 10:1 became high compression. How you should look at that number is....you can run a lower psi but achieve the same power then someone with a 9:1, using the same turbo's of course. Does it limit the amount of boost you can run.....sure. If you start needing to run higher boost to achieve the power you want then switch the turbo for one that is better matched. I would rather run 10psi and keep my motor cooler, happier and make the same power as someone that runs 25.
In the end though, it ALL comes down to the tuning.

Alright guys, I've been reading around here for quite a while now and see several threads with people inquiring about different engine swaps. (20B, 13B-RE, LSX, SR20, RB2X ect ect)
Lots of options out there for the guy that wants something different but still want to keep their awesome RX-8 platform. Which I think is a great idea, I'm all for engine swaps. Especially engines that can produce realiable power!
I've posted up here in the past and have had alot of response but nothing really ever came through. Now that winter is approaching us here in Canada its about time to start booking in major jobs while the cars are in hibernation.
I've been approached about the 20B swaps, LS1 swaps, 13B-RE and 13B-REW swaps, one person asked about a 4G63 (Eagle Talon/Mitsu EVO engine) swap.
It can all be done if the engine measurments are right and even if they are not it still can be done. The biggest thing is $$$.
Anyways, what I'm getting at is that we have some room in or winter build schedule and we would like to do one of these swaps for someone. Someone willing to spend a bit of money on getting the right parts and having a clean 'from the factory' install.
So shoot us your ideas and what your goals are for your car and we can work something out.
Currently we are swapping a Cosmo 13B-RE engine into our own '04 GT and plan on daily driving it with 350 whp while keeping all the factory accessories working and having it pass a legitimet e-test. So tearing into an RX-8 is nothing new to us.
Just figured I'd try to help some of you who are interested in such a thing. I could post some pics of our shop and some of our work if anyone would be interested who doesn't already know about us.
Thanks
Joe

I had a 05 GT and sold it, the renesis is a piece of crap period. It was boosted I made 300whp and kaabooomm. Now I own a 2008 350Z with the new HR motor and this thing stock would pull on my 8. This is also a nice motor to add and boosts like butter in n/a configuration.
I think the RX8 is one of the nicest looking cars on the road, and the LS7 would make it a true beauty. 505bhp N/A is what I would love to see, I am thinking of getting a wrecked 8 and build it my self as a side project.
Again thanks for giving these blind and ignorant fools a option to the slow *** two rotor dirt of a motor

You appear to be the type of person who makes snap decisions without understanding situations. It's a bad life philosophy...
You blew up your motor...so its junk...good call there...
You probably did it as cheaply as possible without understanding how anything works. If you had any type of clue, you would not make a gross generalization based off a single example.
What you did was buy a steak taco...add tons of hot sauce...hated the way the hot sauce made your taco taste...and so labeled the steak taco crap...
You fail to understand how the world works bud...

Got to drive a buddies RX-7 w/ LS1 in it...
I hate to admit that it felt great having all that torque...
I did not like the handling of the car at all compared to the RX-8 tho...
Both the RX-7 and my RX-8 are built up for track duty so neither are slouches by any stretch...but they DO feel different and the LS1 is approximately the same weight as the 13B so it was not the change.
I came away from the whole thing with a new found appreciation for the RX-8 chassis and handling characteristics. It just needs an extra 100WHP to be perfect.
At the track I do not have problems pwning C5's or anything with obscene amounts of power. I just need a little extra juice for the straights. In my case I'm probably going to be getting the Esmeril kit and keeping boost conservative at first.

Thank you for taking the time to post here. I agree with you on just about everything, but why a EVO motor lol.

Wow you guys are terrible...
Anyways, since all of this engine swap bashing began and some of you provided me with a few links to look at, I see that some persistant people are making some decent power with these FI kits.
Since I'm taking the Renesis engine out of our RX-8 and was going to toss it in a corner for something to kick around on a rainy day and some of you think I know nothing about the Renesis and turbo setups, I've decided to fabricate my own turbo setup on our engine block. I'm going to be running it without any emissions, none of the factory ignition setup, and doing away with the factory ECU because I'm going to put it into this:
My 1972 Mazda 616
Originally equipt with a 4cyl piston engine, the 616 is the brother to the Mazda RX-2 which came with a rotary. Really the only differences between the two models.
My plan for this is to use a T04R BB turbo on the stripped down Renesis block and control everything with a new Haltech E6X using LS1 coils, which is the same turbo and ignition setup we used on our FC racecar that made 320whp at 11psi on pump fuel.
Should be an interesting project...

I don't blame you...you specialize in engine swaps, and we are telling you its pointless at this point to do. That sounds like money walking out the door...of course you are not going to like it.
I'm certainly glad you went out and starting checking out those links. If you continue to search I am sure that over time, you will change your mind regarding how much power and how reliable the new engine is compared to the older one.

hey guys, i must say that joe is a hell of a guy and very honest, when i had my rx-8 i was considering doing a 20b swap with joe, and i must say if i ever go back to an rx-8, i will go with a 2JZ " the law".... and i would defenetly allow joe to do my car.
ps. hey joe just for the record, how much would it be, just to install the engine and start the car.

Hey Jose, Thanks for the kind words, I haven't heard from you in a while I didn't know you sold the 8.
Installing a 2JZ probably wouldn't be a problem, as for cost....hard to say. Depends on how wild you want to go
Keep in touch if you ever want to do something like that.

with you evil---start dropping to much power in this chassis and the car turns into something else. Been there-- done that.
Yep we do need a little extra--- i choose the pettit kit. she cranks saturday--I added a few little extras. But that should get the power to were i want it.

It really only needs 100 extra HP to be a finely balanced sword...Anything above that is simply gravy...
Old video: http://video.google.com/videoplay?do...35336967829043
I let C5 pass because he kept reappearing after the long straight...but I would lose it in "teh twisties"...but you can see why he reappeared after the long straight...OMFG the acceleration on that thing is no joke at all...fun was had by all...
I'm not trying to out accelerate a C5...just not lose as much ground on the straights...If I can get that, I'll be a happy camper indeed...

Just wail until I post vids of my pratt and whitney equipped RX-8 swap.
It takes a while to spool the engine, and in city traffic it's very very slow. But when it does get to stretch its lets even the batmobile's got nothing.
