So regardless of price and hp, which one of these, as seen here http://www.turbo-kits.com/rx-8_turbo_kits.html, is easier to install, more reliable, and is the ball bearing upgrade on the SFR worth it?

I assume the SFR is harder to install but is it something the average guy could bolt in over the course of a weekend with normal hand tools?

(srry if this is in another thread but a quick search didn't give me the answers I wanted)

One advantage of the GReddy kit is that so many knowledgable forum members have installed it, and can help if you get stuck. I only know of one person with the SFR kit, and I'm pretty sure they didn't install it. So just keep that all in mind.

Thnx, that is a good point. I guess I'll get a GReddy

Your going to do the install with hand tools???

Fanman

Big difference between the 2 kits. Question you have to ask yourself is how much power are you looking for, and how much are you willing to spend. Two most important questions.

As for the ball bearing upgrade. It is worth every penny.

Im stuck in your spot too xenocide.

The main thing i first looked at was price... it seams that the Greddy will put a few more bucks in your pocket.

As far as installing the kits... for the Greddy a lot of people can do it for you without doing something wrong. The ssr/sfr kit probably would need a very experienced mechanic/tuner... and you will pay up for that.

performance is hard to go on between the two for now, because as moostafa29 has already mentioned, not many people on the forum have the kit or have it installed. The only thing to look at is what the ssr/sfr people claim... so trust them or not its the only info anyone really has on the kit. But Greddy's kits is all over this forum and people really seem about satisfied with the product.

Or last you can wait another year or two for the other tuner kits to come out.

hope this helps!

what is it with ball bearing turbos whats the difference??

rkostolni

SFR will give you more top end power but the boost comes on much later. Greddy gives almost immediate boost, but less top end. So you need to figure out what you'd rather have. In my opinion, for driving around town you will like the Greddy kit more.

I for one wouldn't want a turbo 8 that dips at 7000rpm. The main reason I bought another rotary was for its high revving nature. Without that you might as well buy an evo or sti......

I say go for the sfr if you can afford it.

rkostolni

sfr dips at 7k also.

"Usually" ball bearing turbos spool up a bit faster, also more reliable than standard bushing turbos.

Fanman

7000K is the result of engine flow, from the dynos all the kits seem to have that dip/ decline at 7000K.

I agree with Raptor wait for the PTP turbo kit to come out. It will be the most complete & highest hp.

I just bought a 06 rx8 and dont know if it would void my warranty? Also give me a CEL light?

Fanman

Absolutely void warranty. CEL is regular occurance.

Whats the PTP turbo kit????

adrian-1

It's the "Pay To Play" (PTP) turbo kit. It costs $20k!


just kidding. look here.

PTP has my vote and thats what im waiting for.

We have sold about 15 kits since our original release.I know there are quite a few people who have bought them off of these boards so I am surprised that there is not more of the guys talking about it. We have sold quite a few more kits recently so I know people will start popping up with their impressions soon enough.

You can do the install with normal hand tools.The install is pretty straight forward. The other thing is that we have real dyno results. The tuning and dyno chart is from a Dyno Dynamics which tends to read lower then the Dynojet so that is something else to take into consideration.

That is fine but you will be giving up at least 80 horsepower at the wheels based on the average gains I have seen with the Greddy system

Moostafa29

^True, I think those who have gone the Interceptor route are the ones with the higher hp numbers out of the GReddy kit. I'm not sure what the average emanage owner is getting, but I'd assume if they have completed the 3 fixes, it should be better that what people were getting in the past.

SpeedForceRacing

From what I have seen.....most people are getting anywhere from 200-240 WHP out of the Greddy kit with moderate boost pressures.

Fanman

it looks something like this :

1. Greddy Turbo kit (includes EManage) + peripherals (BOV, gauges, pod, etc) = $3500 = 230-240 whp
2. Greddy Turbo kit + Other FMU + peripherals (BOV, gauges, pod, etc) = $5000 = 300 whp
3. SFR or PTP kit + peripherals (already has BOV, so gauges, pod, etc) = $7000+ = 340 whp+

These are prices without installation (figure about another $1000 for that). Decide how much you are willing to spend, how much power you ultimately want, and the rest is pretty easy after that.

I know there's no definite answer to this question, but what do you guys think the life expectancy of the engine (assuming proper maintenance and care) would be with the SFR? Greddy?

Fanman

I don't think anybody knows. Nobody has put 100K miles on these cars with the kits. They've only been out a short time. Properly tuned & supported I don't see a durability problem with the engine that has a turbo kit on it.
