I love my 8 but I feels it needs more torque in the lower RPMs but I really don't want to turbo it or supercharge it . My RX8 is a stock manual 2004 and I am just starting auto cross . And i am just getting into cars . So I = noob .

Please help

 

The aftermarket performance section is your friend...

next time test drive a car before you drop 28K on it. Or at least do your research on what kind of freaking engine is in the car.

 

You have a small engine. That's the nature of the beast. There are 2 ways to get more torque. 1 way is with forced induction. The other is with a larger engine.

 

That always kills me. They had to have test driven it before buying, but they suddenly come to the realization that it doesn't have enough torque/hp etc... I don't get it.

 

Had you done some reasearch , you would had known that this is one of the biggest complaint with the RX8.

 

Rotary Engine != Low End Torque

Let's disect your post:
As do I.
This is not an uncommon feeling. I would also like to spend my paycheck and keep it too, but them's the breaks.
"I want more power but I don't want to do anything that will add more power. Which way to the magic beans please."
Very cool. A lot of people do fairly well in auto-x using Rx-8s. If you drive well, you should be able to keep your RPMs up and not need much below 4/5k rpms. At least you're not trying to drag race.
You won't get much argument here.

 

lol I love the car i think its one of the best cars out there and i got it b/c its next to ungodly stock it just want to hear about cheaper mods then turbo kits they just kill it . i was looking into a 20b but .. they are autos rights? the 20b cosmo was just auto

 

The 20B swap is more expensive than any turbo kit. People do run MTs with the 20b but I'm not sure which trans they are bolting up. I think Rgonza runs the Rx-8 6spd.

You can run nitrous or you can spend a couple grand for ~20 whp. When you look at the long run, other than nitrous, turbo/s/c is more hp/dollar than just about anything. The Rx-8 has fairly decent intake/exhaust tuning. Most other mods will not yield significant power returns though small gains will accumulate with time. I put in my supercat and I *think* I got more power but not enough to say "kick in the pants".

 

If you are looking at a cheaper mod than a turbo, a 20B shouldn't be included anywhere in there. Plan on spending far more to do a conversion. What transmission an engine was mated to originally is irrelevant. The cheapest way to get more power is with a Greddy turbo system. As it comes it isn't a very nicely setup kit but fortunately there is enough information here to make it nice for the money spent.

Are you in the USMC at Quantico?

 

A 20b swap would cost about $20k+ unless you do everything yourself, and even then it would be extremely costly.

 

At least you're not trying to drag race.

I know the rx8 is never going to be a 0 to 60 i mean the 8 is a great handle car .

I got it b/c its good auto cross car and i got it for 16k and only 30,000 miles and certed Mazda damn good deal on it

I was just seeing if there was something I was missing

like i said I think the car is perfect but the torque and just seeing if you guys had any ideas.

 

i like 20b over turbo b/c the turbo stress the heck out the 1.3 and will cuts the life in half

 

i think the turbo will cost more in the long run .. if i do all my own work

 

i will need new Exhaust header, cataylic convertor, cat-back exhaust, intake header, throttle body, cold-air intake, bigger fuel injectors, better fuel rail, better spark plugs and wires,Lighter pullies. before 20b

 

All of that added up will give you somewhere between 10-15 additional horsepower over stock so don't expect bolt-ons to do much.

A moderate turbo does not really add any stress. Detonation adds stress. A bar of boost is not twice the wear. It doesn't work like that. Yes a bigger engine will not work as hard but trust me, you are not going to do a 20B for cheaper than a turbo. I think you are underestimating the cost of one of those.

 

Are you in the USMC at Quantico? no but i work for them

 

i scared to turbo b/c i still want to have my car in ten years do you think if i turboed it will last that long

 

All that BEFORE a 20B? If you were to swap in a 20B about 1/2 that stuff would not swap over to the 20B. Save your money, buy the GReddy turbo and do the fixes for it found on this forum.

 

For the cost of a 20B swap/setup, you could probably run a Greddy kit and have cash to spare for 3 more engines. Ultimately, the Greddy setup with bonus engines would last longer. The 20B is going to come in used, sit in a fabricated cradle and use a lot of custom parts. It'll run strong and, for an aftermarket swap of that magnitude, it'll be fairly reliable I guess. I don't see how it would be more reliable than a well tuned Greddy kit.

 

Like the others said, the only way to get tons of TQ outa this car, either Turbo/SC or engine swap.

engine swap(20b) will cost you at LEAST 3 times the amount of a turbo kit. not including labor.

Even the cheapest Turbo kit out there (greddy) will cost you MORe than 5 K because some of the stuff that came with the kit are junk, so you have to get *better* parts.

You should've did your homework before you got this car. and as always, SEARCH is your friend, the same ? has been answered like a zillion times.

 

The best way to insure that your car lasts 10 years is to treat it properly. You can make any engine combination fail or last a long time depending on how you drive it and take care of it.

 

Take your car back and buy a Mustang GT. That will take care of your torque problem. Sounds like the 8 definitely isn't for you.

 

You are starting to autocross. Look how well the 8 does against competition with much more torque (read 350Z) and you will see that this is not a problem in competition whatsoever. In buying this car you have traded some power in return for great agility. If you are just desparate for more torque on the street, the answers have already been posted above.

 

So how would you drive the 8 to make sure it lasts 10 years?
1) Agresive
2) Like grandma
3) both 1 and 2
4) Other ; explain....

thanks for the feedback
