Hey guys,

Money not being an issue (not like I'm millionare), what's the best combination of kits, turbo, parts, filters, whatever you need to build the fastest rx8? I don't want to be able to compete against an EVO or an SVT or an STI, I think for the kind of money I paid for mine (mine is fully equipped including gps) I should have been able to beat the crap out of the previously mentioned cars, unfortunately that's not the case. Now I want to be able to compete with a Porsche or an M5 or a Corvette or some hgih performance cars and easily kick the crap out of EVOs SVTs and STIs the way they do it to me now.

If possible, please include websites to where I could get these parts and installations done. I'm located in South Florida.

Thank you

J

 

Talk to Acosta-Racing and get a 20B swap and you'll be done.

 

Well at this time competing with Corvettes is going to be a pretty tall order to fill. Money is definitely going to have to be a nonissue. For sure you are going to have to go the forced induction route. The Greddy kit as it is won't give you what you are looking for. Mazsport is working on a compressor upgrade for it but we don't know exactly how much power it will put out. SSR racing and PTP both make turbo kits based off of the T-04 family of turbos. These turbos are built to spec and can easily push the types of power you will need. Plan on spending between $5,500 and $7,000 just for one of those systems. Then you will need adequate engine management. Mazsport hands down has the nicest system right now. It is around $1600 or so. Then you will need it tuned in properly. Your exhaust will have to be dealt with and you may as well upgrade your flywheel while you are at it. At this time it may cost you nearly $10,000 to get to the level that a Vette comes at off the dealership lot. You'd definitely beat up on the Evo's, STI's, etc... All of these mods together are still speculation as no one has hit that level yet. This conbination SHOULD work. One way to find out.

Since you are in South Florida, look up Mazsport. They're down there too.

 

Where's Ike?

 

LOL, and good post, like always RG.

 

:D

 

^that's what I was thinkin

 

I actually shop around a lot of turbo kits and different websites to find out that with a lot of money on hand you can get the rx8 only to like 300-350hp.

If I'm going to invest $10k, I want some true power. Shopping around more I found out that you can get an Infitity G35 to 650HP!! that's what I'm talking about. So I think I might be changing my rx8 for a G35 soon, then spent $7k to get some true power.

Link to G35 turbo kit claiming to take it to 650HP.

If you have any other suggestions as to what car I can get that I can tweak it and get the kind of power I'm looking for, let me know! Perhaps, that the car used with 20k/30k miles and 1/2 years old does not cost over $30k.

Thanks!

 

1st) Aluminum Flywheel...the best acceleration gain for an NA.

http://www.racingbeat.com/FRmazda4.htm Read everything on that page from Racing Beat.

2nd) High Flow Cat or Midpipe. Midpipe will provide you an 8HP increase per racing beat, regardless of what type of muffler you have.

3rd ) wait for the interceptor X dyno run on the NA, Interceptor can still be used on a F.I. set-up.

4th) Revi Intake ~$500k for 2-3HP....I do not believe this will be usable with F.I.

5th) High Flow exhaust muffler...no difference if you have the midpipe..other wise a gain of 3HP ...for $635.00

Do not believe the SR Motorsports horsepower gains they report....do not buy the hype.

 

Dude...you want to beat a vette and are pissed about $10k? Why don't you go look around at MSRP for this car and a vette and then come back a little less pissed. I'd be happy as hell if I could beat up on a vette w/ only $10k invested in this car.

Also, the G35 (new) is about $4-6k more (at the time I was looking) than a new RX-8. So, you'll spend $4-6k more on the car, $7k on a turbo for it, but bitch about $10k for the RX-8?

Also keep in mind the weight of the car...power/weight ratio on the G35 is going to be worse than the RX-8 too...so you'll need less power in an RX-8 to over power that 650 HP G35 because it weighs, what, 400 lbs more?

I think you need to sit down and think about what you really want to do here....

 

I think the problem is "financing mentality". If you have a wad of cash, it's easy to say 30K for the car and 10K for the upgrades. But if you don't have the cash it's easier to say "finance a car loan for 45K".

 

If you want a dragster for the cheapest price then you are right go somewhere else. The G35 would be a stupid buy. It is 3400 lbs. & for about $10,000 less you can get a WRX, put $4000 into it & get 600 hp. Or for $15000 less get an SRT-4 get Mopar Stage 3 & have 350 ho off the showroom floor with a warranty. Realize the cars that you are talking about base $5K-$15K higher than the RX8.

 

If you want HP numbers in the 650 range....you bought the wrong car....it will take massive loads of work to get any 2 rotor car to 650hp....pean to spend money.....

Also the G35 will put down that much power at the dyno with the right turbo...then on your way home youll ben all you conrods....have fun building the bottom end.

Plus if you have an rx8 now and are going to trade it in and buy a new g35 your gonna lose a few grand right there.

I think you would be suprised what this car will do with 350ish WHP.....

Even with the rx7...going above 500hp in a 2 rotor isnt very common....it gets more and more difficult after that.

 

Some folks have more money than brains, wish I had that issue every now and then :D

 

If money were no object, he did say that didn't he, 20B would definitely be the way to go.

 

650whp LOL,,, since when did the VQ blocks hold that kind of power without building up bottom ends.. Good Luck spending only 10K and reaching the butt heavy G to 650whp without breaking anything.
I would say 650whp in G = building bottom ends, turbo kit, fuel system, tranny, possible axle upgrade, ect,ect = over 20K

 

Buying a turbo kit that has the potential to flow enough air for 650 hp is easy. Finding an engine that can handle it without spending the money to build it up is the hard part.

My advice if you want to beat up on Vettes is to actually go out and buy one! Buy a used one if you can't afford a new one. Then mod it. Start out at their level and then improve it. You'll be faster that way. If you can't afford a Vette, go buy a Camaro Z-28 or SS and then mod them. My friend has an 02 Z-28 that has only bolt on mods and a 150 shot of nitrous that he got for $1000 as a Venom kit. He's got less than $2000 into the car in mods and will currently hang with a Z-06. With the nitrous he's around 500 rwhp. He ran a 12.8 at the track without nitrous if that tells you anything. You can find these cars used all the time. They'll give you the power you want without spending $10K on the engine.

Speed costs money. How fast do you want to go? Another option is to go find a used Turbo Supra and mod it. The stock bottom end is capable of handling over 1000 hp. If you want a car that makes 300 hp at 5000 rpm's but can make 1100 hp at 8000 rpm's since peak power numbers are all that matter, these are the cars for you.

Sorry to hear that you are going to have to sell the RX-8. Good luck on your project.

 

Excellent answer Pcimino

 

You don't think the Renesis could be built to hold 600HP? I mean, if money were "no object."

I mean, with 600 HP I'm sure the lighter RX-8 will hold with a Z-06 too...so, you figure the cost of a new Z-06 is, what, 60k or so.... That gives us a 30k budget to kick its *** lol :D.

 

the tranny sure wouldn't take to 600HP thats for damn sure.

 

Probably true...but it can be bulked up, yeah?

 

with 30K , hell yea~

 

um... the z06 weighs less then most rx8s and has better traction, gearing, aero dynamics, TORQUE, tranny, can fit fatter tyres, etc...

the only way to keep up power wise is if you go 20b which so far has only been done once and costs $65K (with single snail) and NEVER really proved any hp claims. and even then, it doesnt garantee you a kill because dollar per dollar, a z06+the $30k difference = owns almost anything.

i remember when the rx7 ruled A stock track events.... that is until the c5 showed up. now your talking about the rx7s $30k, 4door,cheaper, heavier, weaker, softer younger brother vs a $65k car that out preforms cars that are +$130k.

think about it.

Curb weight of RX8 = 3030 lbs.
Curb Weight of 2004 Z06 = 3116 lbs.

On everything else I agree.

I do think it is absurd to compare a $65K car to a low $30K car. Then some people will say the 2003/2004 Z06 can be bought used for around $34K-$37 now vs. a new RX8, but that is apples & oranges as a used RX8 can be bought for about $24K. Just because Chevy killed the Camaro/$30K sports car long ago doesn't mean all of a sudden we have to compare the only sports car in their lineup to the RX8.

 

With 30k in the RX-8, done right, I think it'd be able to keep up with it.... That's just me, though....

Besides, the only reason the 20b swap costs so much is because of all the labor, you could do it for MUCH cheaper than $65k using your own wrench.

Either way, the Z-06 is a nice car, but not unbeatable by far.

P.S. I love how you uppercased torque .
