Just wanting to know how hard it is to make 400whp in the 8. I have not purchased one yet due to the fact that I don't know a whole lot about rotory. I am very fimiliar with the S2K and the 350z and know they both can make 400whp pretty easy. I don't like the 350z due to its 3200lbs+ and the S2K is a convertible, and I'm not a fan of drop tops, and lets just face it the RX-8 is just sexy and more practical in everyday driving. My main question is what needs to be upgraded to make this kind of power, if anything. If someone has already done this could you point me in the right direction with the cost, reliability, ect... Thanks

not to bust your bubble on the 8 ( its a great car) but 400 at the wheels, consider your bubble popped. 300 is a way more attainable # but thats still gon to take some cosiderable spending. but i will say this car with 300 or so would be an absolute blast.

Mazport is claiming they have a 400whp kit.

It has the potential for 400 whp. That potential is thus far untapped. 400 whp is attainable in this car, but you'll need to solve some issues with the spark coils having the spark blown out around 330 whp. Cooling will also be an issue An S2000 will need a full rebuild before it will make a reliable 400 whp. The 350Z will have issues at that power level after a while too without a rebuild.

Anything is possible with enough money. Send us your car with a blank check, we'll get you 400rwhp.

RX7 engine is your only chance.

the end answer, it is very difficult to make 400 whp

nickmc19

money isn't a problem, i will save by making my own products, i was just wondering if anyone had done it and what kinds of problems they ran into and what not. i have rx7.com not to far from me so i would just have them tune it.

oh and 350z's and s2k's make 400whp reliably all the time, i've built them both and they still run great on stock motors.

Expect ~$10K for 330 hp and a lot more to make more.

make your own 3 rotor engine and turbo it. easy 400hp.

or just swap in a 3 rotor engine from a cosmo.

if money isnt really an issue.

Scott at Mazsport told me he got 374 whp out of an 8 already, he's got 600 whp out of RX-7s before too, so I would think that if you can write a check you could get 400 whp out of an 8 if Scott is you tuner and mechanic.

EDIT: This post is not related to the one directly above ^
Edited the original statement to reflect my opinion more accurately, as well.

Latest turbo kits that are out now are capable of producing 400 on the Renny, but none have done it yet. Whatever MazSport have or haven't accomplished (in regards of the 400 WHP figure) is based entirely on rumors, questionable and can be considered to be nothing more but a speculation, until there are dyno prints that prove it, or them making it a public announcement.
To push 400s, at a minimum you would need to upgrade the fuel system and the ignition. To this day there are no ignition upgrades that can support these 400WHP, at least none that have been proven to work there.

The engine itself seems well capable to do the numbers without any major mods, but no one knows for how long.

I personally had tried to see what are the limits there, and in the past month or so intentionally pushed the car as far as I could Boost wise, and found that it just begins to misfire at 14 PSI and above (which is probably around 320-350 WHP depending on the charge temperature and overall conditions).

Cody Red

it's not THAT easy to make 400whp from s2k, but it's possible, yes.

for the 8, you might wanna check out mazsport.net for there turbo kits. three that provide up to 400whp, but you've gotta have some 'deep pockets' for that.

the z is only 2-300lbs heavier than the 8 but sports four seats. but to have four seats and a lot of power, you might as well buy an evo or sti.

you're smart enough to have come here first, than to have bought the 8 and bitch like the many other people that have done so since it's hard to get power out of the renesis without going FI.

legendkurado

be a pioneer and figure it out.. then post and sell ;p

rotarygod

They are the last people that need to prove anything to anyone so I'm not sure why you are saying their results are nothing more than speculation. Just because you personally haven't seen their dyno numbers doesn't mean they don't exist or the rest of us haven't seen any of them. I assure you they've topped 370 rwhp.

This coming from a garage mechanic should be laughed at. With the reputation Scott has, if he said he has done it, he has.

I wasn't talking about MazSports 370 number. I was talking in general about a 400 WHP (which I am not even sure they ever claimed publicly) I remember them saying that it is capable of it, but can't recall seeing anywhere that they actually did that.

It just so happened that the previous post came before I posted mine, so it looks like I am questioning Mazsport. By any means, I do not. And I apologize if it came out sounding this way.

Mac,
How the hell the place where I do my mods has to do with anything?

He has a reputation that precedes him. You do not.

rotorocks

... and that explains that my efforts should be laughed at exactly how?
But then again, why did i even bother asking? I should have known that you'd just start mumbling.

I didn't laugh at your efforts. I said your statement, in questioning Scott, should be laughed at. I really think you are twisting words just for the sake of argument.

Never mind
