It seems to me that it is very hard and costly to get any power out of the rx-8. Even turbocharged all the numbers i have seen here seem lows. Not hating on anyone but a turbo rsx-s would easily break 300whp tuned and still cost the same or even less. Why is it so hard to get these numbers from the rx-8?

There are two kits: the greddy and the PTP. The greddy kit is designed to be cheap and conservative. The PTP makes 320, and others have gone higher with custom setups IIRC.

 

There are several 300+ whp turbo kits in development. I think the PTP has released a 390hp kit. Scott has a kit with 311 whp at only 5psi. Our aftermarket is in its infantcy give it time.

 

Beat me to it lol

 

the rx8 is just very well tuned stock. needs more time..

 

Yeah but dont forget the RX-8 engine is only 1.3L and the RSX is 2.0. The RSX engine is 150% bigger to begin with. The RX-8 would definately produce more HP per liter of displacement than an RSX

 

not the "it's only a 1.3" arguement again -_-
and who cares, the rsx is a nice car, but the power goes to the wrong wheels

 

The RX-8 has all the power I need. If you want a lead sled, knock yourself out.

 

If you can't drive fast with 90whp, 900whp won't help.

 

Screw the aftermarket! Figure out how much power you want, then figure out which turbo will support that. Go to a shop..have them custom make everything to spec. Done!

 

true. enjoy your rsx-s.

 

Nice math.

 

What Re said was; "Its a bitch to tune but not impossible."

 

Nice I would love to see a front wheel handle so much power, there was a comparison somewhere on the Internet by several US tuners and let's just say the highest powered one didn't do very well.

 

3 years after release and the aftermarket is still small. Sorry guys but if you don't have a good selection of parts by now, you never will. Sure, there will be more things available in the future, but it won't be much more than you have now.

Second, I'm not sure what the OP is here to do other than pump himself up about his RSX. The Greedy kit on the RX-8and the RSX usually yield about the same WHP, the two cars also dyno fairly close stock for stock. The RSX guys just have more choices for turbo kits, though big WHP is a joke since they're all FWD.

Lastly, why the hell would anyone buy an RSX now. The new Civic SI is better in every regard unless you're a badge *****.

 

*** MOD EDIT: Be nice please. ***

 

Why some of you are so angry...DAMN!! Only asked this ? to find out how far u can go with the 8. i plan on getting one but i wanna get to 350whp. obviously thats gonna take some work.

 

All the reading you ever need is right here.

I just wonder why people on this site love to rag on you Ike...You're honestly among the top two or three most sensible, unbiased, reasonable members here...me too :D

 

Ike just likes to kick people off cloud 9 and some people resent him for it

 

Hehe, there was a Honda dealer right next door to the Mazda dealer with a Civic Si on the lot when I got my 8 a few months ago.... It drove ok, but no comparison with the 8... who the hell wants a FWD "sports" car. Thats no fun!

 

i'm sorry but for theptp price it'd just be cheaper to get a 20b engine with 600+Hp w/ turbo and the bang for buck would mkake it worth it

 

While I agree it is getting tiresome to hear the line "the RX-8 market just hasn't matured yet". This is true. ECU upgrades did not pop up overnight for the last RX-7. I don't think it was until ~'98 (someone correct me here) that we even got the PFS "Purple" PMC, and as I recall everyone thought that was a Godsend, much like everyone now thinks the Interceptor is a Godsend. There were always standalone options, but that was very costly. The FD was released late '92, that's a long long time for the market to really ramp up and get going. I expect the RX-8 ramp up time due to small production numbers to be no different, and three years later here we are. I have no doubt Pettit, Axial, Performance Design, and Mazsport will all come to market. And SFR, GReddy and PTP (or you can put down a deposit anyway) already exist, as does Blitz. By my count that's 8 options for a car that isn't exactly a best seller.

 

Sure, if you have the time and know how to do all the fabrication work yourself, and even then I think you won't come close price wise. And you still need new halfshafts, transmission upgrades, clutch, cooling, rear end, motor mounts, ECU, fuel architecture, ignition, upgraded suspension, wider wheels/tires...etc...if putting in a 600hp 20B was that easy lots of us already would have done so.

The Puerto Ricans make it look easy because they have the know how and do it themselves. Pay someone to do all that above, and I'm sure I'm leaving lots off the list, and your cost will be a heck of a lot more than the PTP kit.

 

I'ma make a thread asking who else, besides me, is saving up to send their 8 to 'Rico for a 20B. All our problems shall be solved!!

Wait, what's the gas mileage with a 20B again?
