Which is not as durable as a cast iron manifold. That is why most OEMs use cast ductile iron.
It is also more expensive to manufacture unless you own a foundry like Trust/Greddy does.

Most of what you are looking at in the pics is aluminum, anyway.

BTW - if anyone wants to upgrade your Greddy kit, you can get the secondary injectors from an automatic RX-8 and install them in the second primary position for another 30% or so more fuel. good for another 2 or 3 PSI (11 PSI total).

 

I was thinking that is what made the price higher. Stainless is real expensive right now at work. I like the BTW BTW

 

Interesting Could you explain with more detail please.

cheers

Well, the primary 1 injectors on a "hi-power" RX-8 are 300cc. The primary 2 and secondaries are 400cc.
The secondaries on a "standard-power" (automatic) RX-8 are 500cc. The "standard-power" model only has 4 injectors instead of the 6 on the "hi-power".
If you swap out the primary 2 injectors (which are only used at very high loads and, even then, only at a fraction of their capacity) with a set of secondaries from the "standard-power" model, you are increasing the capacity of that injector position by 25% without significantly affecting the off-load performance of the engine. You total fuel capacity for the whole motor jumps from 2200cc to 2400cc.
You could do the same with the secondaries too, if needed, though the factory injection system is good out to about 300 HP already and swapping the secondaries would cause drivability issues that you would have to tune out with whatever fuel management you are using - and it is not an easy task since the secondaries come on at all different loads and RPMs at varying duty cycles.
The primary 2 injectors only come on above 6800 RPM or so and WOT, topping out at 10% - 15% duty cycle at redline.

 

Well some people already have the e-manage, or the canzoomer, so spending the extra cash for the TSI would be pointless to some people, that's where the savings have gone.

Like we've stated before we aren't trying to compete with the greddy market, as you can see in the component list we include things like a 46mm Wastegate, Aluminum battery box w/ the complete battery relocation kit including wires, heatwrap and shielding, stainless coolant line etc. etc. Basically what we did was include everything in the kit that might be a hassle later on down the road (melting hoses, wires, batteries etc.) so the customer won't have to deal with it.

Simply put, comparing our kit with the Greddy kit is like comparing apples to oranges.

Thanks Mate by reading through the various posts i have hopefully become knowledgeable enough not to have the wool pulled over my eyes

cheers

SSR: Do you have a sound clip (or even better a video clip) of what the blow off valve youve included w/your kit sounds like?

 

Oh bytheway I love how you guys are bitching about the price. Like I saidearlier their kit brings you to a horsepower level equivalent to a $48000 BMW M3 (plus the Rx8 weighs less). Your Rx8 becomes a ****** monster versus what itused to be w/this upgrade. Whatwere you guys expecting to pay for an upgrade of over 100whp? 5000 seems exactly whatI had in mind before the kits were even close to being released

 

We are going to switch out from the Evo Motorsports to the Tial 50mm BOV, it's really sweet sounding!

 

I agree. The kits are two different animals. But, it is not apples vs. oranges.

Your kit, from what has been documented thus far, is the superior kit.

If we figure the standard Joe can get 60 whp out of the greddy kit at 3000... that is $50 a pulling pony. Your kit w/fuel management (go w/the TSI to repeat YOUR results) is roughly $8000 (throw in 1-2 other goodies to repeat your results). From this, you get 110 horsepower. Consumers are paying $72.72 per pulling pony for your kit. Although it does boast greater performance, it is currently not competitive pony for pony w/the greddy kit. Yes, some pieces are of higher build quality, I am not overlooking that.

Finally, I will state that I am not meaning to trash your product in any way. I think that it is absolutely fabulous that more kits are coming out for the consumer. Because when there are more options, there is more competition. This creates lower prices. I also think that the SFR/SSR kit is a real piece of art and it is manufactured with pride. But you have to realize that a person can not justify spending all that money on your kit when another, less expensive, viable option exists. You guys NEED to lower your price in the near future to get a foot-hold on the public that only has 3-4k to spend on their car and want whatever they want NOW.

Other than that, you guys did a fantastic job on this turbo. I commend you also for promising us a product and FINALLY delivering with results comparable to your claims. That in itself adds to your credibility some and surely is appreciated on this forum where claims and boasts always end up in the black hole.

 

I think that point about the price is not only about cheaper competition, but...

...adding a turbo now is an auto warranty void. You want to void the warranty on YOUR new 8? You've got some deep pockets for both a turbo kit and repairs...

$30,000 for an RX-8 plus $8000 (install labor too) for a high power turbo kit, $1,000 - $3,000 for suspension mods... well **** you could have gone shopping for a $40,000 car instead and we haven't even started talking about wheels/tires and bodykits. Getting my drift?

Lastly... what do people expect to pay for 100whp more? That isn't the issue. People are looking for more power... not a 500whp drag machine. I am more than willing to bet that the vast majority of people on this site aren't interested (at least initially if at all) in a 500whp "****** monster." If I wanted that, I'd save time and money... buy a American V8 car, drop on a s/c or t/c and let the 8 eat ****. Will it handle better? Not with out a lot of mods, but what can you do on the track with an 8 with all that power? That's more than you need for "twisties."

To sum up my point... the SSR/SFR kit is great... for those in the market for crazy power gains and a high quality kit. The GReddy kit is for everyone else... those looking for some more power at a reasonable price with reliablility. Which are you?

 

yea i go tto play with all the coolest stuff right before i got discharged. haha nothing wrong with being signal..we combat guys go tto be able to talk to eachother..and lord knows we can't figure that stuff out...hehehe:D

 

Yeah... you have all those DATs, ****, and ground pounders running around w/no idea what time it is, let alone having any command and control on the battelfield. Scary thought for signal guys: during the cold war w/Russia, their initial plan was to DESTROY all personnel and equipment related to signal before ANYTHING else. The signal corps was #1 on mother russia's hit list. W/o signal and communications, you have no command and control... thus, you have small pockets of unorganized resistance units working with some autonomy that are easy to disperse. Ah, I love trying to explain all that to any other branch .

Bottom line.
Signal: You can talk about us, but you can't talk without us!

 

^^hahaha i love that last line that was great:D but alas..i was a glorified ground pounder with explosives..."Marne Sappers through the breach" :D

 

Glorified ground pounder, maybe. But, you are now allowed to wear a really cool tab (Sapper) because your specific trade is a VERY demanding and unselfish one. I give you strong kudos. I also see you are going to college. Have you thought of exploring your options through ROTC to get a commission... or have you already pursued that? Sorry if I pry, it is the professional developer in me that makes me want soldiers to strive for more .

 

alaas i was medicaly discharged due to injury's suffered before and during the war, i'm okay just can't shoot my rifle or do half of the things combat engineers need to do so to sum it up i can' tre-up or get back in until i'm fixed....but that probable won't happen for a loooooon time. but i had a good run and it was fun with lots of memories...i got no complaints.

 

First of all, I have no clue which kit is worth what, but from an unbiased standpoint, y'all are giving SFR/SSR an unfair amount of crap, compared to greddy, who pounced on the first-to-market position, as well as the low-price position. From a pure business standpoint, claiming both spots is unsustainable, and will usually reflect the age old adage, you get what you pay for, and in this case, it was something that *may have been* rushed to market. None of these kits are proven, and in the end, it'll be one year to two years down the road that determines who wins this race, and you'll be able to follow the trail of blown engines to find the loser.

Also, when it comes to comparing the $3,000 Greddy kit and the $8,000 SFR/SSR kit, these prices are like comparing the $28,000 out-the-door price for my RX-8 GT with the $47,300 retail price of a BMW M3. These are completely different price points you're talking about. Greddy retails for much higher, but you can get it for roughly $3,000. SFR/SSR is advertising (retailing) their kit for the $5,000 - $8,000 that we're throwing around on this board, but I'll bet that whoever buys this kit will buy it for much much less.

Good luck to all the teams putting together FI for the 8. I'll go with the winner two years down the road when the vote has been recounted by hand five or six times...and when the attrition of competition has dropped prices down a little bit more...

I dont know your specific case and if you are not comfortable in sharing on the forum, you can PM me if you like... but if you suffered said injuries while on active duty, The Army is obligated to either, in some way, fix it or compensate you for the loss. Unless, of course, it is not a mendable injury. But, I care not to pry. If you wish, as I stated, PM me and I can surely find some AOA for you to pursue. God I love Army acronyms...

You may also want to talk to the ROTC office on your campus. Usually, there is an O-5 there that you can speak w/personally at any time that their schedule allows. He/She can do A LOT to help you out.

 

I can't agree more.. I love you guys..but quit the bitching please and just have some frickin patience.. good things come to those who wait.. and if you're complaining about getting a turbo for our rx8...a turbo with QUALITY parts...shoot.. wth people?? YOU GET WHAT YOU PAY FOR.

i'm playing the waiting game myself.. gonna see em all..rp's..greddy...this one.. and others.. makes no sense to jump on the turbo bandwagon right now..

and whatever the price may be.. thanks to ssr/sfr for even making a turbo for us..I for one appreciate it. sorry for all the whiners on here.

 

HAVE YOU GUYS THOUGHT ABOUT GETTING A ROOM?
Arent these threads long enough without extra fluff?

 

New Rx8? Ive had my Rx8 since August 2003 and only have about 20k miles left on my warranty. Itll takeme about a year and a half to finish it off. The way I see it is -- why postpone the inevitable? Wait another year and a half to drive my car the way I always wanted it to be when I could just do it now and end my suffering?

I dont autocross or do anything fancy really. Im not interested in anyof those other mods. Only the turbo kit.

Whatyou said is true for SOME people on here but let me behonest w/you - in my case I am upgrading primarily for better straight line performance. Like someone said earlier if I were concerned about outperforming other cars on the track I wouldhave already done **** loadsof suspension mods and said **** forced induction. A lot ofmembers probably wont admit it on here since its a general no-no on this forum - but they really do have an inner desire to woop some straight line *** - even if its from a stoplight.

Im definitely the former. Do I reallythink that majority of the people on here looking for a turbokit are in it for better track performance? Id say HELL NO - more of them want it for the speed. Most people donthave as many opportunities to enjoy a cars handling capabilities in regular day-to-day driving situations as they do w/speed. That need for speed isan urge easilysatisifed by simply being on a straight open road and pressing down on the gas. A lot of us would loveto take our cars to the track everyday if wecould - but realisticallythat is not an option. I already love the way my Rx8 handles - and nowI just want fulfillment in the one area in which I havefelt my car has been lacking in for the 16months Ive owned it for. And I wouldnt call SSR/SFRs kit a "crazy" power gain. Its notlike theyve turned the Rx8 into a 1000hp Supra - well at least not yet.

 

Question for SSR/SFR or anyone else.
When all is said and done, (parts, install, gauges, misc stuff)
I figure ~4500 for the GReedy and ~10,000 for the SFR.
The GReedy is a great kit and a great buy. It delivers exactly what is advertised.
I am leaning toward the SFR strictly based on power output.
My question is about the stock drivetrain at these power levels. (240 <-> 300+)
Can anyone comment on the durability ?
I'll spend the 10k on the kit, but I want to know if I should expect to have to upgrade
other parts. That will effect my decision, since 10k is already over my price point for FI, but I can probably swing it.
Thanks all.

What about the people that want show winning looks as well as a great increase in power?

 

Depending on the power levels your shooting for with our kit your not going to spend $10,000. If you want about 270 WHP all you need is our turbo kit ($4995) plus the pre-tuned TSI ECU ($1399) and depending on installation (if your doing it yourself or not) then you're good to go. Or if you want to tune it yourself, or if you even have your own engine management system then all you need is our turbo kit. Think of the versatility with this kit, some people out there don't have any Engine management so we have the pre-tuned version for them, now for those that already have engine management and don't want to spend the extra money on it then we have the base kit which they can tune themselves.

 

Hey Keith SFR or SSR How many injectors are are supplied with your upgrade. (R)
