Option C: Wait until there is more than two options on the market. Especially if they have a better ECU solution than the emanage. Maybe RG or someone else will get this sorted out soon.

8thRider

maybe I should just do a ECU tuning and some supporting mods first?
and save the rest up for a possible later turbo kit?

Fanman

Realize that if you do te ECU Tuning (Canzoomer) you are essentially wasting that money as most turbo kits come with engine management (like Greddy Emanage). SFR is offering their kit with no fuel management (though still $5500). Also be careful if you get a hi-flow cat unit, as it caused (random) backfire on my turbo kit. Wound up pulling it, now selling it. Even an air intake, like the RB REVi or the AEM unit will be useless if you get the turbo kit later on. Look for a Catback exhaust. Later if you decide to get the turbo kit then put in your stronger clutch with a lightened flywheel.

8thRider

so basically besides the exhaust, clutch and flywheel, others are kinda useless if I deicide to turbo later on?

8thRider

guess ill save up money for turbo later until warrenty is over~~...~~
should I tune the suspension and change the tires or get a body kit for exterior while I wait?

Fanman

I got the RB springs & swaybars. Love them. If you change tires (at the end of the stockers) go to 245/40/18's More common size, better choices. Body kits are nice too.

Other mods will give you hp gains when you are NA (such as CZ unit, RB REVi air intake, Ram Air Duct, etc.), just realize that if you plan on going to a turbo kit later, they will become useless (could always sell them).

8thRider

thank you, I guess ill get my car to the nearby garage once Im free~~

8thRider

hmm...
it is a good idea to just sell them afterwards^^
since I do want some good power while I save up money for the guarranty
If I get the following mods, approx what WHP will I be able to push? Can I pull a 350z or maybe even an STi?

1. RB Revi air intake
2. RB/Other Cat back exhaust
3. SR Motorsports/RP Performance/Canzoomer Hi-flow Cat
4. Canzoomer Piggyback ECU (Although have a good mechanic tune it. Also might looked at a used one that they have here occasionally on the For Sale board.)
5. RB Flywheel (Have to take apart & drop the transmission though)
6. Zex Nitrous w/55 shot jet (Talk to people like Charles R. Hill - Resident RX8 nitrous guru)

Sigma

All those mods, minus the NoS, might get you 20-30hp depending on your success, if any, from the CZ. You might surprise a 350Z, but you wouldn't be beating him, and still no chance against an STi.

I don't know what the NoS would net you. More than other the other stuff put together though.

Moostafa29

With all those mods (mayb 205whp), plus the nitrous, you should be able to beat a bone stock 350z, and sigma is correct in that you still would have no chance against an sti.

Fanman

I ran Addictive's car. He has the Zex system (55 shot) with a test pipe. When I was at 6 psi (4 at the top) with my hi-flow cat he gave me all my car could handle. On the Malibu Cruz there were a couple of straights where he gun it & I was behind him (single lane road) with another 6 RX8's behind us. He was running out of the giggle juice but the few runs he did his car was fast (almost ate his rear end on one run though). I'm not sure how much faster my car is now that I have turned up my boost a bit (fixed the leak) & have the C02 system. There is a guy running a 75 shot with his Zex on a bone stock car. Ray (Charles R. Hill) said it is possible but if you have the other stuff (more hp when you are not on the juice) you are limited to the 55 shot.

I've personally run an STI when I was down in san Diego. It will surprise the guy. We gunned it on a freeway onramp onto the freeway, and a few miles on the freeway & he couldn't catch me.

8thRider

with ur mods.....
of course.....
looks like NA will get me nowhere...
turbo...

8thRider

if I dont do any other upgrades, only the greddy turbo kit, will I be able to smoke 350z?

Sigma

It would become a driver's race at that point the cars would be rather equal and you should win "most" of the time.

Fanman

It will be a much better race that's for sure. One poster here trimmed about 1 sec. off his 1/4 mile time without tuning. The 350Z is about .7-.8 sec. faster in the 1/4 mile so it will be close. Trust me I made my share of stupid mistakes. I havea set of pullies that are useless on my car, a hi-flow cat that is now useless. a set of gauges that i am now selling, my cat back exhaust that I might be selling soon. I made the mistakes. I'm just telling you how to get the most hp without going through the pitfalls that i did.

Actually if I had to do it all over again I would probably go with the NA mods, then get the nitrous setup. The turbo has cost me a lot more than I origianlly thought.

jwbond

fanman, what additional costs were there w/ the gredddy? I would guess just a clutch, but fill me in.

Also, i would think nitrous would kill the renisis faster than 6psi from the greddy...any thoughts on that?

Fanman

Tuning, tuning, tuning. Installation costs. clutch, gauges, gauge pod.

I properly done nitrous system (Zex has a nice wet system),shouldn't put any more stress on the engine than a turbo.

8thRider

But with only NA mods, how much whp will I be able to crank out at most?
of course, with the nitrous, it is obviously better^^...
turbo costs a lot, but dont you think its worth what it costed?

Fanman

With : RB Revi air intake, Ram Air Duct, Hi-flow cat, Cat Back Exhaust & tuned Canzoomer I would think you would be somewhere in the 200-210 whp range. With a lightened flywheel I reallt think you will give a surprise or two to an S2000 or G35/350Z.

Like I said, if I had to do it all over again I would have done the nitrous route. If you want to pull a nitrous & sell the car later on it is relitively easy. With turbo that is not the case. I do like the extra tq. on the low end & the extra power everyday, but looking back I would have done the nitrous & called it a day.

Again no BS, I'll tell you like it is.

murix

Or you could learn how to drive the car in corners, go to a track, and be competitive with a stock motor against a 350Z and STi being that it would be a drivers race.

Fanman

That to.

A suspension setup, nice set of lighter rims & lighter, grippier tires can't hurt either.

8thRider

yea...suspension setups are nice~~
but i think the stock suspension is ok for now, thnx for the rotary^^
I just feel that my 8 lacks power in the straights...ARGH!
nitrous are nice, but Im not familar with those monsters yet...
they give you instant boosts? how long can you hold onto the nitrous button? and how much whp boost does it give? -_-

Fanman

Nitrous is really not that great for autocrossing or street racing (when you don't know when you will need that extra power). More for 1/4 mile racing or canyon runs/set races.

For example the Zex system runs 55,65, or 75 shot. The 55 shot if you do about an 17%-18% drivetrain loss will give you about 46 whp. 75 whp would give you about 63 whp.

8thRider

so...
if my car is mainly for street purposes, turbo will be better than NA?

8thRider

will the intake and other NA mods be used if im going SC later?
or...is it useless as well?
