yes but its not practical
i get a dented fender because some jerk opened his door on my car i have to pay like $2000 to get it fixxed and order parts from japan or if it gets stuck in ahail storm
but also i like the rx-8 because its different
but like you said there will be a sc or turbo kit coming out?
and what about the rx-7 i heard?

the rx7 is meant to be released in 2006(correct me if im wrong!), but its just a concept right now, which means that all could change.... but it would be turbo, rotary, two seats etc... again..

aftermarket for the rx8 is going to be very very good, but the car has only been out a few months max, but hopefully by january febuary time aftermarket will be starting to break through, i think the car has a lot of potential to be in the 12 second range given the right time, parts, and love :D

Mazda hasn't even committed itself to anything yet, and noone but rumour mongers said anything about a turbo.

Skylines are not "ALL that", trust me. I lived on the little island of Okinawa for a couple years. Skylines are a dime a dozen. Yes the GT-Rs are rare, but you can get better performance for the money.


I may be biased but the 8 is a better looking car by far. It's not in the same performance catagory, but for the money you'll get an incredible car.

For ex-Supra guys... or anyone I guess

What makes a BPU a BPU? Like what is the definition, and did the definition just evolve among the tuner community out of nowhere?

also, just to gratify my curiosity... what modifications were included in a BPU, and what performance increase was typical?

bpu=basic power upgrade, bpu's are basically, i/e/h

they are available for any car im thinking but most ppl say "a supra with bpu's will beat ..........(place car here)

im pretty sure thats what bpu means, unless im thinking of a completley different thing

Actually, BPU was coined by the Supra twin-turbo world. People discovered that some very reasonably priced and simple mods resulted in an astounding amount of horsepower.

On a Supra, BPU consists of a cat-back, downpipe, boost controller, and a boost cut controller of some type (to keep the ecu from cutting fuel due to higher boost). That's it. With that combo, 400-420 RWHP is EASY to obtain, and is still very solid, reliable, and easy to drive.

The twin turbo Supra is definitely a solid platform to build a LOT of power on - that engine is one strong bastard.

BTW, this is kind of off-topic...

that basic power increase list also includes turbocharged rx-7's.

i've done the same thing, 3" exhaust, intake, FCD, and gotten some great gains from it.

Combined intake and exhaust mods

The thing I anticipate the most are the results of the performance impact for combined intake and exhaust upgrades...

ie; gross improvement with K&N intake and a Borla exhaust, etc

I'd imagine there's potential for 20~25 rwhp gains if this is done right - but the impact on the cars everyday lower rev driving nature will be a big issue too. (You've got to live with the car!)

Any facts or theories out there on this and how it will impact or enhance the cars character?

...these are mild modifications. the impact on drivability and fuel economy should be very small, but noise on both ends will surely increase.

Yes, I think the installation of headers would be like building a ship in a bottle.

It'll be interesting to see what headers do to the low end of the torque curve too. I want the best of both worlds, more power up top and no loss of torque down low ... with the only cost being a little induction noise and a slightly louder exhaust. (oh, I want world peace too! )

:D

A header should be able to be installed from the bottom no problem.

yea, im guna be interested in how much the headers are for one and secondly, what kinda performance gains they will give, i am going to try to get some when the price is released, i think they should be able to be installed from underneath??

intake and exhaust will actually help your fuel economy by presenting less of a restriction.
As long as you drive the same and don't use your extra power anyways.

I want to know how he came to the conclusion that 20-25rwhp is waiting with an exhaust and an intake.

Oh yea, intake (15hp) and exhaust (10hp) = 25, rigght?

riiiiiight.

10 for intake and 10 for exhaust.

20 hp max.

I could see another 10hp for header and high flow cat.
