Looked like a nice Vette, and it's cool you used to hammer on it yourself.
Then you also know the level of modications it takes to strengthen ANY drivetrain of ANY production car to withstand 1000hp+. I come from the GTO world where we have to invest in expensive Kaaz rear ends, one-piece driveshafts, hardened halfshafts, built T56's, etc., so we also know the pain.
Point is, the comments from simplephp "just buy a Corvette" are superfluous. It will cost a **** ton of money to get ANY car to 1200hp and streetable, so any argument about cost is ridiculous. It's going to be expensive, so I'm saying that starting with an RX8 doesn't matter once you reach this level. Every damn thing is going to be replaced, strengthened or upgraded anyway, so the investment is going to be huge no matter what.
I couldn't make the same argument if all he was doing was swapping in a stock 350hp LS1. Then the costs vs. results don't make as much sense. I think this project is cool, and I just don't get the negative comments.

Oh no, I totally agree. No need for negative comments here, whether you like the project or not you have to appreciate the work and skills it will take to pull it off. I am doubley interested in this project because I have an interest in both the RX8 and LSx worlds
And you are right about the expense of a high power driveline. I did all my carnage with less than 700RWHP. It takes exponentially more money and skills every couple hundred HP up you go. I pretty much pushed the limits of what a corvette would take on stock bottom end and upgraded driveline. The next step up was an expensive forged bottom, new fuel system, custom solid torque tube, built tranny, solid rear, ect ect.

Props to RGONZA though. To each his own; I'm a rotor head to the end
.Note: Abel's power is on Alcohol

There are race RX8s making more horse than that. My friend Abel claims close to 1700. i'm not sure if that's to the wheels.

I'm just not sure you can say that tube chassis drag car is a "1700hp RX8"
Know what I mean?

Still, incredible project. Makes me feel like even more of a wuss for being nervous about replacing my own air filter.

That's a good way of saying it. It's does look it should be there.
I keep sizing up the height of the intake manifold and the fuel rail in my head. It's not too much taller than the heads, but its gonna be pretty tight under that strut brace.

Found one! ..one sec I"ll get it uploaded to a host.
^ that was my 2nd engine and in the box behind it was my 2nd or 3rd differential :D

3 rotor can make a lot of h/p---buts its the torque that is the difference between these 2 engines.
I am sure he is going to do a big stroker version 580 cu in +?? The 3 rotor tq band will not match at 1200 hp big block v/8.
i agree with you on the cam lift--and like you and i said--lifter/pushrod work will have to be done(still use the exhaust valve seals?)-- I also wonder if he is going to a low lift prototype rocker arm set up to maybe help get up to that 8.5K he mentioned? i wonder what "total" lift will be and i also wonder what duration he will be using.
I also REALLY wonder about the rear suspension and diff
That is going to be more work than getting the engine in the car.
Thank God we have pioneers around like this. Hats off to ya Bro!

After some brief research and thoughts I'm beginning my planning on an ls3 swap should take me about 5 years to fine tune everything buy a DD and transform the 8 . I'm fine with a bolt on LS3 for now, anything over 500 whp is pointless for my intentions. The weight of the engine is low enough the LS3 weighing in at 415 and the renesis weighing in at 344 71 lbs isn't room for concern if the mounting is done correctly.
So yea I'll get back to y'all in 5 years.

Not all of will go the 1200hp route. An LS1 with headers, cams, Z06 manifold will be plenty!
Re: the 71lb weight difference, put the battery in the trunk and you're down to an extra 36lbs up front! Not bad. I did notice in the pics that it looks like the radiator is as far forward as the bumper grill.

I do not believe it is just the weight itself that needs to be made up for, it is the position in relation to the wheels and the size of the motor that would be more of a factor than just the increase in weight. You put the engine farther back towards the middle of the car like the Renesis and you get a better weight distribution. The Renesis is located behind what would be the front axle. This engine being larger in size will be located right on top of the front axle and hence more of its weight will be on the front wheels no matter how it weighs in compared to the Renesis just because of its size and position relative to the axles. So yeah handling will be negatively affected a bit, but he will probably find a way to make that better than stock if he wanted to.
But come on guys he knows exactly what he is doing and he will pull it off one way or another, he is not only a frontier finding problems we have not even thought of yet, he is an innovator and will find solutions to those problems before we even know the problems existed. I cannot wait to see how it turns out!

I mean, I could have 10,000 lb-ft of torque, and if I try to take off on a wet street, I'm not going to break anything because I'm just going to spin.
This thing is still going to be light but have enough torque and horsepower that anything in the rear, short of a rolling pin with Hoosier 40 treadwear rubber coating, is going to vaporize if you lay into it. I don't think the point of the project is to tub it and stick slicks under it.
I don't know what that cam is going to do exactly, but I'm guessing that LSA is going to move the torque curve higher in the RPM range. Maybe thats what he's looking for. With a 427, it's going to make torque down low no matter what, and could help with the drivability and a more linear power curve.
RGonza! We can't read your mind! This is fun and all, but, man, give us an update tell us what's up!!!

one day in 5 th gear he will punch it and when that monster gets on it will break something so if u have 10,000 lb-ft of torque dont go out of 3rd or else
I get what you're saying, but, honestly, there's no way he's going to put all that torque to the ground... right?

Personally, I would have gotten a carbeurator and had it stick through the hood. But I'm just old school like that, I suppose.

Plus, 1200 can be a little much for a clutch to handle. Powerglides/automatics are really the only way to go.

I don't even like anything retro, like shaker hoods, on our GTO's. On the RX8? It would like like some schizo "Mad Max" car.
Paging rgonza!!!! Any updates?!?!
