Just ordered my kit from Jason at the RX-8 Store. PF Supercars will be doing the install and tuning. Will post pics once I get her up and running. Thanx to Jason at the RX-8 Store for a quick response! I will send you a map when I am done!

AWESOME. i can't wait for the results. keep us updated and posted on everything.

Way-to-go-bro! Let us know all the details and the differences to stock once its up and running.

I look forward to hearing details on tuning and performance from this first round if turbo kits. Interested to know what it does with our power band.

Congrats, can't wait to see how it turns out.

oooooooooooooooooooo anouther person i am sooo jealous of...congrats...can't wait to hear how it goes and how much more ZOOM it adds:D

Congrats man, the era of FI 8s is beginning.

Congrats man. How much are they charging to do the install?

congratulations...cheer on the delivery service to get it sooner!!

Congrats! Welcome to the club... FI club that is.. hehe

Rub it in thankx :)

There is now a subset club in RX8 club haha

Mark my words, it's only a matter of time till there is a dozen or so FI kits on the market...

Mark my words, it's only a matter of time till there is a dozen or so FI kits on the market...

Allright, I'm marking them........J/K!!!!!!!!

I think I will wait for the SSR kit or the PTP kit to come out before I jump into the FI club....

Then again, Hymee's supercharger kit is looking pretty damn good too!!!!!!!

SSR/SFR has come out.

SSR claims that the pricing from them will be cheeper than from SFR, and SSR also claims that they are tweeking the tuning and getting around 335whp and will post dyno sheets on their SSR-ENGINEERING website.

If they get 335 hp that would be phenomenal. That is like 150-160 whp more than a stock RX8, almost double the hp. IF it is reliable. That is the big question with the Renesis & this massive of a hp increase.

When I was considering the nitrous install on my 8 one of the axioms I had counted on was the idea that most factory cars are capable of a 50% increase in h.p.(at the fly) with very little affect to the reliability of the engine. If that is the case we shouldn't be too surprised to find numbers like 330 h.p. as a starting point in the modding process. Whether through 7 pounds of boost, a 100 h.p. nitrous kit, or a combination thereof I think the RX-8 will show itself to be very responsive to such mods and we will have some very fast and quick cars when we hit our performance plateau.

Took the words right out of my mouth..... :eek:
I definately believe that this car has a lot more potential than most people realize or want to think. I think that we are just scratching the surface right now, and I can't wait to see what the near future will bring us.

But in talking about the potential of this engine not as much in putting out power but in terms of reliability are we limited ? If we could strap a big turbo on it, or turn the boost up to 12 psi but the engine will only last 6,000 miles who will do that ? Wasn't that the problem with the RX7's. You could get insane amounts of hp out of them but the question wasn't if it would break, but when. With the Renesis will have have to tear apart the engine & throw in new apex seals if we want 300+ hp ? I'm all for more hp, but I guess Charles is in new territory, and so is SSR/SFR in 300+ hp. I'm just looking for more hp but still want the reliability to be almost on the level of a stock car. I know, isn't that what everybody wants ? But I guess if 5/6 psi is the max then I will stay there and not push the engine.

I think guitarjunkie would have a thing or two to say about rx7's not being reliable and lasting at high hp..

I'm talking stock engine. I have seen some ridiculous RX7's but they all had beefed up apex seals, and more. Until people start introducing reinforced apex seals for the Renesis I'm just worried about how far we can go with this engine in stock form. I guess Charles is the first to really push the envelope.

Who said 5/6 psi is the max that the renesis can handle?

Who said 5/6 psi is the max that the renesis can handle?

That's just the level the Greddy & SFR/SSR turbo kits are set at (for Turbo) & some of the superchargers too. From seeing some of the problems that some of the SC kits have been getting at around the 385-300 hp range it is a bit troublesome (RB had some issues at around 285 hp that they were testing on one of their Renesis engines). Could be a fuel capacity issue, as there have been insights into hoe the returnless fuel system pretty much maxes out at around 60 hp +/- for the upcoming kits.

The sum total of my experience with the Renesis and mods has been that the engine can handle abuses that the previous models have not been able. So far I have accidentally revved it to 11,500 rpm(second gear at 80 mph), hit the fuel cut HARD while under nitrous boost(unexpectedly broke the tires loose near the top-end of second gear), subjected the Renesis to loads of detonation(during nitrous testing), and several strip-type passes on it. All this and the engine still runs great. I am in the high 12's for 1/4 mile times using a handful of bolt-on mods and a 55 shot. I would say the RX-8 is a "wolf in sheep's clothing" in stock trim and if the owner chooses can be a very competitive vehicle. Although not a drag car it can hold its own in the 1/4 mile and as far as wheelhop goes, with the pre-load removed it will hook up pretty good. On the matter of 285-300 h.p., I would venture to say that the fuel pump is up to the task but the factory injectors may not be. The odd thing is that the intake/MAF are said by a local tuning shop to be good up to 500 h.p. due to the size of the pipe and the type of MAF used. Coincidentally, the MAF is the same one used in the WRX/STi.

Charles

Good tuning, plenty of fuel, is all that is really needed .The only thing in question now is the compression ratio being a little higher. This might be a problem but we will find out soon :) .

Mazda's APEX seal is AWESOME. No need to change them IMO.

I am willing to say, with confidence, that 2005 will be the year of the RX-8. I am sick of hearing and reading about the 350Z so I hope I am correct.

Charles

Amen to that!

There seems to be a school of thought that by changing out the apex seals and some other internals you can lower the compression ratio to accomodate say 10-12 lbs of boost.

Maybe I'm just misreading you, but how do changing out the apex seals lower compression? The only parts that need adjustment to lower compression are the rotors themselves. But the issue was how much metal was in the Renesis rotors that they can be refabricated in these respects. Racing Beat barely got anything out of their recent lightened rotor offering, so maybe there isn't enough there to work with?

My kit just got here!!!! My car is now getting a motor from mazda under warranty!!!! So it will be a few days before I get my 8 back. I will start a new thread when I start.

-Ryan

Fenman I agree with you, I really do not care about Turbo's/ SC if they are not going to be reliable. I don't know much about T/SC but if they can not go for 100,000 without needed a rebuilt then I dont' want to mess with them.

I also worry about what it could do to fuel economy since the 8 is not great for that, but I hear the change is slight so I dont' worry too much about this one.

The main concern is the reliablity issue. I also do not care about going to 12psi ect, I'd take 7psi and be very happy with it.

My plan for my RX8 is to lower weight by a bit (lighter flywheel, rims, pully's) lighter battery, exhuast, and maybe break system...if that exsist at all. Run it for a while with those upgrades (of course some other things too) then stick a SC or Turbo on my 8. If I could get to at least 300HP (which apparently is no problem) but better yet 350HP...I would be ONE HAPPY GUY. At 3,000 pounds and 350HP...that is fast enough for me...who am I racing?

with the pre-load removed it will hook up pretty good.

Mr. Hill...LOL,...what do you mean by that? I heard wheel hop get's real bad on the 8 so that is definitely something I would want to reduce. Is there another way other than putting on a "gosh...the metal bar...GOSH, sorry I'm running a blank on it's name..ARRR" in the rear...I hate seeing it across the trunk like that.

awesome!!
congratz!!

A friend of mine is a Greddy reseller and says that the kit is 4195$. It comes with a lovely CARB sticker, so it is supposed to legal for Cali residents.

I'd get a new friend if he sells you the kit for that much...there are a few places selling it for less than $3k shipped ;) .

And so far it's not CARB certified...

I can get it for a good price, I was merely quoting the MSRP for the kit.

To change the pre-load in the rear would require adjustable length suspension arms in the 5 link set up. Instead, I have always suggested that the first mod a new 8 owner perform is to replace the rear swaybar with the Racing Beat bar. With that, the hop is eliminated. I still have traction issues through first and second gears but at least the tires stay planted.

Charles

Please confirm if this kit recently received CARB certification. I'm sure there are at least 10 people in CA that would buy it the minute they heard that news verified.

^^^what he said

I cantbelieve there are so many people jumping on this kit when its probably going tobe one of the slowest ones oncethe others arrive.

alot of folks haven't yet, they have just expressed interest

From what I heard it is on backorder till the end of FEB. I mean I don't know how many Greddy sent over here to begin with but I thnk they have sold a whole lot of them.

March is what I heard.

^^^ hehe good it'll give me a few months to ha;f a year time to save up for a kit:D and by then we'll all have nice impressions of the kit from you philodox

From what I have seen of the other kits on the market the Greddy is going to be very popular. For one you are getting a complete kit with ECU for a little over $3k. All of the other kits on the market are $5k+ and that doesnt include ECU.
Another thing is the Greddys ECU is preprogrammed which is great for the average RX-8 owner that doesnt have a shop close to tune it.
With these other kits that have large turbos, you're car has to be tuned or your going to blow the motor.
I would also suspect Greddy will come out with a kit with a larger turbo like they do for alot of other cars.

Right, and when they do release another kit with a bigger turbo, it'll most likely bolt onto the current cast manifold that they have with the current kit. All you would need is to upgrade the turbo, intercooler, and piping.. or at least I would think ;)

it will give them time to make some numbers.

My prays have been answered!

Of course I would play it safe and get some new apex seals when they come out, a new biggger, better radiotor to help cool it, all the JIC Suspension bits I can get my hands on, a really nice JDM Mazdaspeed Strut Bar (the really nice aluminum one that connects 4 points in the engine bay), chassis stiffening bits, the Mazdaspeed body kit, some Volk TE37's, brake lines, calipers, maybe slotted roters, etc...

Of course I would play it safe and get some new apex seals when they come out,

I know someone with a 7 second FD who still has 2mm apex seals with no problems.. I don't think 3mm make much of a difference except in the wallet :p

The matter of apex seal size is one that is always up for argument. Racing Beat seems to feel that although the 3MM seals are stronger they are less flexible so there may be no real benefit overall. Of course there are always anecdotal examples to prove any point one wishes to make so, like everything else, it is a matter of choice.

Charles

The main benifit of rhe 3mm seals are that they can take a little more abuse if you happen to detonate.

The dirty little secret among rebuilders (OK, its not all that secret, Cameron from Pettit freely admits this) is that the real reason to use 3mm seals on a rebuild is so you don't have to buy new rotors. The groove wears over time and becomes out of spec for the 2mm seals, however with a bit of machining it can be made to fit the 3mm seals perfectly.

Ya, you probally can't wait for the kit to come. I saw it being installed on ninedeeps rx8 it looks really really nice. I wouldn't be able to wait haha. good luck with the kit

Ninedeep is a tool. I met a guy that works with him and he also siad he was a tool. I have my kit and it needs a bigger turbo and I/C. after my trip to the dyno to see how far the turbo will go. After that I hope to get a gt 35/40 bb and remove the front crash bar in favor of a 3 row greddy I/C.

Yeah, but for the current setup of the GReddy kit, the I/C is sized perfectly for the amount of airflow it has to cool off.

For the price of the kit you get more than you pay for IMO.

Definately. I agree with you whole heartidly. You would be hard pressed to find a complete kit that is truely bolt on and also with engine management for a similar price point.

I think this will be a great kit for people who want to maintain some reliability and want more power for typical daily driving. Other kits (like SSR) will come out with more HP -- but the larger turbo will also have negatives for those wanting a daily driver. Plus -- my kit was only $3275 shipped for the complete Greddy, BOV, flange and a turbo timer -- it is going to be very tough to find a kit that has a higher cost/benefit ratio IMO. I will be complete with install and hopefully some tuning (if we can get the Greddy code) for $4k :D
