Give me a firm date when you can take my money.I mean cars been out a year now and still nothing.Is this ever going to happen?

 

Let's not get too hasty around here. Along with FI comes a new ECU mapping scheme, the ancillary parts to make all of this happen, and fabrication of brackets and stuff. This all takes time if you want it done right.

Charles i do believe i understand what it takes to place FI on a car.My point is that alot of people here claim "oh next week dynos and cost will be available"is all crap.Not getting hasty and im not impatient person I just hate false claims and promises.

 

WTF: Why don't you make FI for the RX-8.

If you can do it faster than these other guys, then you may have a reason to complain about them.

Sorry if this sounds harsh, but I don't see anyone owing you anything.

Also, you shouldn't be in such a rush. If someone puts out a hastily made FI, I sure wouldn't want to be first in line

 

this is going to get nasty

 

I would love for WTF's car to be the guinea pig for some type of FI, that way if it blows the engine, we can all be happy it wasn't us.

Honestly, this thread sucks.

 

Where do I sign up??Im not a pansy like some others that i know.I would give my car up in a second to be a test mouse.I have even offered it to some already.I believe everyone here is missing my point.Im not upset with the wait im upset with false claims of completion.Hell SSR posted a material list like they were all done.3 weeks go by and still nothing.There are pictures of turbos everywhere but nothing to buy.

 

It's usually hard to know how long something will take, especially if you're dealing with a new car and diving into unknown situations where you're learning as you go.

 

Do some RX-8 owners nurture bizarre behavioral characteristics?

The first group complained that the mileage wasn't good enough, and if only they had known, they would have bought a Prius. Great.

The second group claims the car isn't fast enough, and there aren't enough aftermarket parts to make it faster.
Wonderful.


Why did you buy the car in the first place?

 

Knowing what i know now i would have bought a rx-7 again and another daily driver of some sort.I like the car dont get me wrong at all,just need a little more under the hood.

 

I understand WTF's position on this, and I know he understands the perspective of the designer/manufacturer(s). There is nothing wrong with the market speaking loud and clear, and I am sure he is just saying what several others are thinking. I wouldn't be surprised to find out that he, and others, thought I was full of hot air because I have mentioned titanium power plant frames and a new design for a header but have yet to deliver. My personal concern is balancing the upgrades to my own car(so much fun!!) while also finding the money to pay for the raw materials on prototype products. Those items are still on the project board but I think I will wait until I store the car for the winter before moving forth with them. As a customer and hopeful developer at the same time, I am empathetic to opinions like those from WTF and I appreciate them. WTF, thanks for your candor on the matter.

I drive about 500 miles a week and on average I see ONE RX-8 during my travels in TWO weeks. I am sure the others here can say similar things. This brings to mind the following points How many of the few RX-8 owners out there.

1, Want to add aftermarket FI based on the reputation the FI RX-7’s had?
2, Willing to void their warranty on a car that’s in its first year?
3, Want to be the first with a FI RX-8?
4, Want to make bad gas mileage worse?
5, Have a extra $3,000-$5,000 around for a risky MOD?

I think the real reason for the delay is a combination of the above plus the fact that there just are not enough customers to make this type of MOD profitable for a company to do. The reason a company would want to make a FI kit for the RX-8 is to make money, not make your car go faster.
I am happy with the power of the RX-8; I can merge onto any hwy quickly and pass an 18-wheeler with ease. Also knowing that I cannot “dust” 350 Z’s at lights keeps me form doing something stupid that can either hurt others or myself. What more does someone need? Now if Mazda sold 100,000 RX-8 in its First year you would see a FI kit. My last car was a 2001 Chrysler PT Cruiser. They sold about 150,000 in it’s first year and there were FI kit in the same year. It’s a simple supply / demand issue.

 

PLease dont preach to me about sales or marketing when u have absoulutely no basis for your statements.

 

Yep

 

Rx8's did manage to sell 75k in the first year, overshooting Mazda predictions, so I guess that means we should see one soon. I do agree that if you set a deadline then you should meet it, don't do empty promises.

 

But that's the point! You'll take a well used car, over a new one with a fresh design for a faster quarter mile time? That makes no sense! And if it mattered so much, there were scads of choices out there to make.

No matter what, some people are NEVER happy.

 

Hey WTF -

If you have some time and money (and don't mind being without your car for a few weeks), you can bring it down to me and I'll build you a system.
I'm not too far away from where you live and I've built a few custom turbo systems in my time (well, more than a few).

I think a lot of the delay from the other people that have laid claim to building a system for the 8 lies in the desire to make it a kit that can be installed on other people's cars with no fuss and no damage or claims.

A custom system will not fill those goals - it will only be for one car and YOU will bear the weight of any difficulties.

That said, it is really only about the welding. Everything else is proven technology and the parts are there.

Figure on $2500 to $3000 in raw parts and $2000 for labor and tuning. That will get you a basic T3/T4 intercooled system running about 4 - 6 PSI and 80 to 100 HP.

I won't do it on my own car yet because I don't have the money laying around at the moment and I want to wait out my warrantee.

I just installed an E-Manage on my Miata - I was using a kluge of mechanical controls before - and I have been running 12 PSI on it for 5 years or so using a custom system I built in my garage.
My MX-3 V6 was the same way, but I sold it to a guy in Canada who seems to be enjoying it.:D

It just isn't that difficult to build a system - it just takes planning and a willingness to face the possibility of finding your motor's weaknesses very quickly.

 

YTD sales rx-8 10456
YTD sales 350z 14469
Considering they have at least 3 to 4 weekend install FI kits for they z i believe these numbers warrant one?
150000 pt cruisers doesnt mean a damn thing.Different market, comparing a 4 door $13000 car to a $30000.Not to mention i see alot of old ladies driving PT's.

 

Nissan uses the 3.5 V-6 in practically every model they carry along with a few Infiniti’s Developing a turbo kit for the 3.5 V6 is not a bad business move. Mazda needs to get more 13B’s out on the road to make mods for it worthwhile to producers. 150,000 PT Cruisers in one-year means Chrysler did a good job. The first two years however they were underpowered and turbo kits soon came out. They are purchased by all age groups and are all over the road main reason I got rid of mine and got a RX-8.
WTF, I gave my thoughts as to why there are no FI kits, why do you feel no one has brought one to the general public yet? Also based on those sales figures I wonder where all the RX-8 are hiding? I see way more 350 Z’s on the road than RX-8’s

 

Well your kinda right with your thoughts on the 3.5 nissan.While the plumbing will remain the same for the most part the tune will not.As far as im concerned thats the difficult part.Look at the boost for a procharger kit for the g35c compare it to the 350z.Even though those cars are very close in every aspect the tune is still different.I agree that once the leg work is done for one the others are easier but far from finished.

Look at the new post just put up about the trust system.The J-spec is finished and they still cant confirm a U.S. kit.Ive contacted some local tuners here and very well may end up trying to complete something myself.To answer your question as to why its taking so long?Hell i dont know.Whats scary is a couple people ive talked to that are in the process of releasing something are not even including engine management.Maybe they know somehing i dont.I can tell you what im hearing is that the MAF sensor does not cooperate well.

 

I think there is a delay in developing FI for the 8 for several reasons. First, most shops don't have the money to buy their own RX-8 outright so they need donor vehicles. Remember how much flak Al from SSR took when he surveyed for a donor car? Second, when the 8 was released to the public most people were fearful of testing the limits of the 8's internals. After much discussion with resident sages on this forum we all agree that Mazda would, most likely, have built the Renesis with certain improvements in strength. However, most others are still hesitant to have confidence in the strength of the Renesis. Third, most people who buy these cars have no interest in modifications because they are geezers like me whose wives would kill them for hacking up a $32K car. That's why I have no wife!! You should have seen my salesman's expression when I told him I would begin mods immediately. Lastly, the ECU being encrypted poses certain problems for designers of FI systems. There is a possibility that the factory ECU could be used up until the point that the injectors' duty cycle becomes a problem. Same with the signal voltage from the MAF. According to MazdaManiac there is only a 20% window that can be used. Any more than 50 h.p. increase requires a new MAF or conversion to MAP sensor.
