Engine swap projects
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

Seeing as I'm the evil one of the group...here's my unsolicited 2 cents...
Yeah because we all know how unreliable the stock engine is...
Or they could drop 5k and get the same if not more power instead...Currently FI options are beginning to really become much more available and increasingly very formidable in comparison to the options.
Unless someone is wanting for personal reasons to drop a significant amount of money and take a difficult route...it simply no longer makes as much sense.

FI engines were desgined for boost. High compression FI engines are built to be drag race engines and get rebuilt almost every weekend.
I always said if I got an RX-8, the first thing I'd do with it is take the Renesis out and put in a reliable rotary. Stock port, stock twin turbo's 13B-RE. Not saying that the Renesis is unreliable, in stock N/A form its great.....if you like driving an underpowered car.

Engine swaps? This ain't no damn Civic.
All I hear is people bitching about the power, so they want to drop a bunch of coin on an SR20 swap? Some dreary Nissan 4-pot? Doesn't make any sense to me. Neither does dropping 10 grand on an old 13B just so you can have the illusion of reliability. Your plans are nice and all, but you know, somehow I just don't see reliability as a defining characteristic of an engine transplant. Running any car with any engine it isn't defined for is probably going to lead to more rather than fewer problems.

Anything after 400+ whp is technically "unknown land" as far as I am concerned. I have yet to see anything to make me feel like the tuners really have a firm understanding of the next "hurdle" or if one exists. But we will see...
I will have to disagree that the "older" power plant is the better alternative in light of the recent changes in aftermarket support available now and in the near future.
I do understand what you mean, there are alot of great turbo and supercharger kits out there for the Renesis. Maybe the times are changing, honestly I haven't looked at any FI kits mostly because I think its a waste of time to try and boost a 10:1 compression engine running pump fuel. How long is that going to last for
The problem has always been engine manglement, and ignition. Those hurdles have been or are being overcome with impressive results.
This either demonstrates your lack of comfort changing old ways, or simply a lack of knowledge. I bet if you spent some time and do a little bit of searching on the forum, your mind might be changed.

Seriously, do more research before making such statements.
No offence man, but you choose to ignore the info that has been proven, tested and implemented over and over.
Stop making yourself look ignorant.

Over 20K miles daily driven out of it's mind @ 11 -12 PSI and drives like I just put the turbo in yesterday.

Donno, never bothered to dyno it. but I target 12:1 AF under boost and live in a hot and Humid state, so my car sees 100F+ temps near every day in the summer. I tried to go for higher boost too, but like the others found the ignition limits.

i was talking about the distance. and judging by what you have wrote thus far on this page i wouldnt choose you to work on my car. no offense but it doesnt seem like you have done your homework on our car or our engine.

Well its been a while since you have checked, but so far the only limitation is the stock ignition system. The kits available now easily do 300-375 reliably. The new one out recently "Esmeril" is reporting to have figured out an ignition "fix" of sorts for the stock system, for example.
That I definatly agree with, having an engine management and a good igniton setup would be key to having a reliable FI car.

I'm sorry that it sounds like I dont know much about the newest turbo kits for these cars. Its probably because I dont and dont care to either.
RX-8 owners from Canada and the north eastern US have emailed me asking what else can be done to improve the power in their cars while still keeping it reliable. They have heard too many stories of these expensive Greddy kits not working so well. So I suggest swapping engines to an engine already built for boost and that can make decent power reliably. Seems like a logical thing to me, most dont realize how cheaply and engine swap can be done for.

But generically your looking at starting 6k up to 12k for one of the best kits out there all inclusive.
A swap and turbo setup is going to be higher after everything is said and done. It also will have lots of kinks to work out before its "right".
One of the most recent advances which should further drop the price of FI kits will be the COBB AccessPort. Once that is released, a standalone will not be required.
We are also starting to see the same power levels...and extrapolating the data...potentially even more.

LOL, well I'm sorry to say, but I started this thread with the intention of getting rid of the stock engine because it doesn't interest me as far as reliable HP is concerned.

You also again indicate that you do not care to change old habits...that said, you are probably barking up the wrong tree here. Most of the users here are now only interested in FI of the current engine, or a 20B swap.

2.the rx8 owners in canada and the NE US look to have been schooled on the renny the same way you have "word of mouth" and have clearly been misinformed. if everyone is asking you for ways to make more power because of the greddy power numbers maybe you should do your homework first before advising them. how can you tell them to swap a engine when you dont even know the rennys market??? and the greddy kit is not expensive compared to other kits....OR YOUR ENGINE SWAPS!
3. I believe you may know what your doing as far as putting a new engine in the 8. but i dont think you now what the renny is capable of. wait for the igintion upgrade to see what power the renisis can yield before making more outlandish statments.
4. what is decent power to you?? 300whp 400whp?? i think you should see esmerils numbers now and new numbers before you go yanking the engine out of your car.

I wouldn't do a swap. But if I were to do one it would probably be a LS2. They're bullet proof, light for their displacement, compact, easily modified, and of course very powerful.

A buddy has an RX-7 w/ an LS1...pushin something like 500HP NA...
It's utterly disgusting...
Yet...I have trouble not trying to hump the car....

Met a guy at Road America a few years back that had a NA LS1 in a '93 RX-7. He'd bought it without an engine, and said he picked it up because in his mind the chassis was more suited to be a weekend track car/racer than the C5. He had time slips from the car running in the mid to high 11s.

Rotary , eh?

Once the ignition gets sorted out, which looks to be rapidly approaching, the Renesis should make ~350whp on ~14psi on pump gas without aux injection. You are getting into the same power range and you're using much less boost. Coupled with the already proven ability to withstand some detonation the reliability edge is going to fall with the Renesis.

At 25psi, it should be more than 400+hp...upwards of 500hp.
And I don't see how that was on strictly pump gas alone. Gotta be some sort of auxillary injection, at least.
