600 HP? LS1 plus mods Really, that is going to be very difficult with a rotary. It has been done, though. Not going to be streetable at all at those levels, though. Instead of shooting for such a high number, why not start with something more reasonable. I know that several guys on here will tell you that 300-350 hp is more than enough to scare the crap out of you in these cars.

well i like to do that but i really wanna stick with the rotory

Check out the following users:

steve84GS TII (he has 300 or so HP) passes CA emissions
680RWHP12A (Robert) last I heard he was pushing 720HP to the wheels (not streetable, at least not at those levels)
Directfreak - not sure on his current power levels 400hp? Perhaps more.

There are others in the 250-350 hp range too. It is best to start out small and work up if needed. You have to remember that these are small, light cars and don't require that much power to go fast. Personally I would shoot for more like 300 RWHP. I'm sure you'll find it plenty and will be significantly less expensive and more reliable than going for say 600hp.

Then your going to have to be realistic. Your wanting to take a 130 hp engine, and mod it too 600 plus? I'm sorry, but even a small block Chevy isn't "streetable" at that level. If you take and double the horsepower, it will be more than you, or the car can handle. When you start getting to that kind of HP, you will have to build the rest of the car to handle it. Suspension, brakes, transmission, rearend, unibody (yes these cars are unibody), fuel system, and probably a whole lot more. There are a few (very few) first gens over the 600 HP mark. Why don't you ask one of them what it takes?

ok well how would i get to that level 300-350 i ve been told to go to a machinist and have them machine me two rotors and an ecentric shaft out of a aluminum titanium alloy

What??? Not true at all. Just check out the turbo 2nd gen and 3rd gen guys. See what they have done. Also, as I mentioned, there are 1st gen guys running in the 300-350 level range. Start by looking at posts by those users (probably steve and directfreak would be closest to what you are looking for). Just search and do lots of reading. That is the only way you'll know what it takes and you'll also need to figure out a budget. As Sam said, once you start doubling/tripleing power, you need to upgrade pretty much everything else.

djessence

first of all why do you want 600 HP seems like a pretty rediculous number if you actually want it to be streetable as youve said. Your chassis/unibody needs to be completely reinforced to take anything near that kinda power and still be able to be driven.

Try doing a search about performance mods and horsepower in the first and second gen engines. Search is at the top right of the page near the end of the banner.

are you serious?

We aren't the lounge. We behave here (well, most of the time anyway).

Here is a list of mods that you will need.

- Standalone w/ experienced enough person to tune it
- Huge turbo (GT42 size or larger)
- Custom manifold
- (1) large wastegate or (2) smaller ones
- All other turbo peripherals (ie BOV)
- All supporting mods inside the engine
- Huge injectors probably a 850/1600cc combination. Might be too small.
- Larger fuel pump
- Larger fuel lines
- All other fuel supply requirements (ie RRFRP)
- Upgraded clutch
- Custom Radiator
- Water meth injection, ethanol or race gas all the time
- Time & Patience
- And the key ingredient lots of BOOST

That will get you there, I am sure that I am forgetting something. You will also need the drivetrain to put the power to the ground and the brake system to stop you. Don’t expect to spend less than 20k to make a car that can produce and handle.

It is apparent that you are a new member and have not been around rotary motors for an extended period of time. That is fine; we all had to start somewhere. But before you get made fun of severely I would highly recommend that you take a moment and use the search function. Try the single turbo section, there is a great thread in there that discusses 500whp on pump gas.

Now that his question is answered I hope that the mods will close this thread.

I was thinking the same thing.... wait for it.. wait for it... Now we just need a "what kind of oil should I use" thread.

I'll be the first to say it.. this thread is kind of retarded.

Pics of current car that all this power is intended for...

I am sure there are much more important issues that need to be addressed before said HP numbers can even be thought of, so...

I want my car to be faster than the Veyron.

sneezix

Look at it this way: You can drive your car faster than you can drive a Veyron.

(Of course, if you find a way to actually get your hands on a Veyron, give me a call!)

I don't think the 600 HP is "reasonable" in terms of being street legal. It's simply too much power. Road racing is not all HP it's a combination of things. I like to think of a performance tuned FB as a fine Samuri sword. You want to make the 2 sided blunt hammer...

Why? What are your plans for the car? Track? Strip? Pantie dropper?

600RWHP?! Streetable?!

Even with my (albet still mostly on the drawing board ) idea of dropping an RX-8 13B and some other major modifications... I'm only expecting to make 300-350hp...

MAYBE... if I am lucky and the chassis doesn't fall apart on me I'd try and turbo it for 400hp. But keeping that toy streetable will be the biggest wrench in my plans so far!

God knows the amount of trouble that you would have to go to make a Rotory Powered 600HP FB Street Legal.

I'd say stay in the 300-350hp window... The power to weight ratio will be close enough to match some of the higher preformance cars, notto mention the fact that with proper suspension tuning, chassis stiffening, and other parts you can make that a finely tuned zoom-zoom!(+1 on the Katana Metaphor )

Why not try a TII Swap? That should be a decent start to what your goal is... right?

Well, I think I've rambled enough...

Holy crap DemonSpawn all of those smilies in your post is making my ADD act up, my eyes keep darting from place to place, aaaaaaahhhhhh!

Sorry, I felt kind of ADD myself...

Ever seen the Lotus Exige? That car doesn't have that much power to it but it doesn't need a whole lot to begin with because it, just like OUR cars, is very light. You'd be amazed what the right suspension and slight engine upgrades can do for you.

+1 on the lotus.

it is the same weight as our first gens (absolutely base is what 2200 lbs of the frist gen?)

and they develop 180 HP. So 600 is rediculous and asking that diminishes your credibility, especially after your other threads we have seen
