How about a turbocharged version for the power hungry.

I think all models are gonna be N/A... I wouldn't be suprised if racing beat or mazdatrix or some such company is thinking about an aftermarket turbo kit.. That'd definately be sweet.

 

Hey Guys,
This is my first post. I read in an article that mazda is working on a turbo system for the Renesis engine. Also that it has been said by mazda that this engine is better equiped to handle forced induction than the previous RX-7 engine. Sounds like good news to me, even if it would have to be aftermarket. I am in the market for either an RX-8 or the Nissan 350 Z. But without forced induction i will have to go with the Z because of its more impressive power output. Even though the RX-8 should be a better handling car. Any Comments.

Same old dicision variables:
Price, preferance, performance..

 

I would think that any turbo development would be used on the possible 4th gen RX-7, not the RX-8. There might be a Type S or something RX-8 in a year or two that has 280 hp .... but I doubt it will ever be turbo'd.

And I'd take it over that scarry ugly Z anyday. Although the 8 isn't as good looking as a 3rd gen RX-8, it still MUCH better than the 350Z.

 

i like better the idea of turbocharger on the rx8

 

I am personally going to wait and see how the RX-8 sells. I want one badly, but hope Mazda has no issues with their new rotary engine. If they make a T/C renisis, so much the better.

Awaiting the price and release of the RX-8...

In about 2004, my 91 will be ready for an engine swap. Hummm.

 

Why can't Mazda take a lesson from Toyota. Toyota produces a NA truck but you can walk into the parts department and buy a factory approved supercharger developed by Toyota's TRD group. The nice thing about it is Toyota will cover the supercharger under their factory warranty.

Why can't Mazda do the same? That way those that want the power can get a factory approved blower and those that are fine with stock don't have to pay the extra money.

 

For that matter, why can't Mazda build a new REPU?

 

It would be cool to have Mazda do a new REPU. But don't hold your breath. Mazda has no plans to do it and they do not see a market for it. When the REPU was built there were no other small pick up trucks with any power. The REPU was alone in that regard. That has changed in the last 25 years and there are plenty of small trucks with a good amount of power.

 

Where did you read this article?

 

the one hope we can have, is that Japanese car manufacturers have done away with their "gentlemen's aggrement" of a 280ps limit. Hopefully this is true...

...cause with a factory turbo, this car could push 300ps...of course, it's still a torqueless wonder

 

Well heres my Two Cents... a designer of the RX8 stated that the car will be very easy to tune, I heard a rumor that the RX8 will have a compression ratio of 9.5:1 and I am not too sure, but that could make it turboable (I am just getting into Rotaries and I really dont know what too high of a compression is on them, please tell please tell). Only problem I see is that engine bay and that big ol Plastic thing, i hope that gets Nixed before production, I really do. It would be good for making a sort of Ram Air Induction as seen on the soon to be extinct WS6 Trans Am (and I dont care what many people think about domestic automobiles, but this is an American Icon washed away). one good thing about it though is that its plastic, and we all know that Id rather cut regular plastic, then metal (Regular meaning not Kevlar filled or Lexan).

Thats a dollars worth of stuff, and I gave you two cents....What A Deal!

 

A REPU would be nice, nothing beats the sound of a chainsaw powered truck :D

Veloracing your a damn post *****...j/k i'll be in yahoo chat later

 

So, you want to go fast? Weight reduction is ALWAYS better than power boosting for increasing performance, unless you just like to spend lots of money..

 

Of course, you can do both..

 

Just stick one of these good ol' 20B's in there and you'll do fine :D

 

Look for companies to make low compression rotaries, they would allow for high boost and nos, if thats your bag, im thinking of turboing mine, but then again im also worried about it. Anywho, we have to see how much more weight reduction can be done, this is already light light car. Me I started a diet. :-D

 

> Thats a dollars worth of stuff, and I gave you two cents....What A Deal! <

Being a post ***** is ok if you've got quality stuff to say. Just don't become AOL minded and you'll do fine

> A REPU would be nice, nothing beats the sound of a chainsaw powered truck :D <

Heh, none of the REPUs around my area have that sound. I've almost forgotten what it sounds like. Around here, they are either loud, throaty, full of bass (at low RPM), or all of the above

Mazda ought to just take a B4000 and install a 3 rotor renesis. All they need now is to sell the RX-8 in production quantities to fund their racing and 'rotary experimental' ventures. I'd like a Cosmo21 and a rotary B4000. Hmm, R4000? :D

 

okay so maybe not a dollar, a nickle maybe?

 

Nah, it was worth at least 8 cents

 

Well ok maybe not a chainsaw, but certanly a lawnmower on steroids. I like the idea of a 3 Rotor Renesis in the B2400 :D I have only seen one REPU my whole life

 

I wouldn't be holding my breathe while waiting for a turbocharged RX-8. Mazda went out of its way to develop the REnesis engine as a normally-aspirated powerplant reaching the 280hp (JIS) limit covered by Japan's Unyusho (Ministry of Transportation) 'administrative guidance' regarding power levels. Despite a handful of 300hp (JIS) cars appearing (one STi Impreza as well as Toyota's Yamaha-powered Mark II and Crown Athlete, both officially certified as 'tuner' cars modified after final assembly, just like the STi), the Ministry of Transportation has not indicated it will relent on the 280hp (JIS) cap applied to Japanese manufacturers for their mainstream catalogue models. Nissan has been pushing the issue with the R35 GT-R, but so far any suggestions that 300hp (JIS) be sanctioned have been met with a polite, but resolute "taihen muzukashii" - literally 'very difficult' but in fact a Japanese way of saying 'no' without saying 'no'. While the administrative guidance is non-binding on any car exported from Japan for delivery to another market (such as North America), in Mazda's case a heavily modified engine might not make economic sense.

Mazda is also still stinging from warranty costs the FD and (to a lesser degree) FC RX-7 wore. Development of the REnesis was predicated on a 'non-turbo' draft from the guys holding the purse strings, all of whom have long memories.

Some studies have been done on a LPT system (though nothing in hardware - all done as computer simulations), but a traditional turbo set-up isn't in the cards as a factory or factory approved option at this point in time. Bear in mind that Mazda is a much smaller company than Toyota or even Honda, and just hasn't got the resources - in terms of facilities, manpower and funding - as those two. Thinking along the lines of 'yes but Toyota is able to...' doesn't take into account these differences in the area of staffing and finances. Or company pholosophy.
