Turbo kit bolt on??

[Pirana]

The problem lies on the factory ECU, even the Mazdaspeed, which is supposed to be tuned, has problems. From hesitation to overly rich. Tunning is the key to a reliable system, also installation like Spool said. Most problems arise from people wanting their kit to do more than it was designed to do i.e. 12psi from a 6psi design kit. Choose one that gives you what you want and stay with its recomended parameters. If you do not see one, then ask to built one specifically for you. Like I have said before, I chosed the HiBoost because its Haltech computer, it offers everything I wanted, performance and looks. We have yet to test it like the others, but that starts next week.

Yes many people have issues such as stalling, parts macking out, runnin to rich/lean ect. They key to reliability is installation. Thats why its sometimes better to get a kit installed by a pro. We have people that buy kits and we never hear from them again. Then we have people having driveability issues for months and we get calls from them frequently.

I agree with you 100%.

In a turbo engine just a vacuum line plugged in the wrong place may make a huge difference between a smooth drive and a rough one.

If you are not 100% certain that you can do it right, you'd better take it to a professional to do it. I'll save a lot of trouble.

That's my main fear. The computer and the installation. I'm pretty confortable with all of the maufacturers and I believe they care about thier products. But, they are the experts on their systems. If I went with any of them, i'd either want to drive up to them, or have the hook me up with an expert down here for that. Installations i've seen run from 700 -1000$. That's can be 30% of the price of the turbo kit though. Not that it's an unfair price, it just adds to the total.

I agree with Pirana, I like to see a system with a computer fix too, not just an FMU. From what i've heard, that may be the weak point in the kits. Hate to change the direction of the thread but i'd like to hear what the manufacturers have to say about the efficiancy of FMU's etc. as I see it as an important factor in the kit.

Yup

We install now, I posted in a thread I started about pricing ect.

Whats wrong with an FMU? They are great for what they are meant to do. You try to overstep the parameters however and you will have problems. Just because you cannot run a gizzilion psi on something does not mean its bad.
We are still slaving over the microtech that offers the best tunability and hp, however this is not for everybody. For those that want a simple fuel control device for 7psi or less the FMU does its job. Yeah it will not extract every last hp out of the car but thats what stand alone engine managment systems are for

 

[keyserscott]

okay. good point. so you say an FMU is good enough for an auto with a 4 psi kit? There's just some companys who would disagree. not sayin you are right or wrong. just sayin theres room for argument. so far thre are 2 kits out their utilizing a standalone or a piggyback. make a compelling argument. this is a 3K purchase for most.

if I buy your Stage 1. How many gauges will I have to buy to ensure it's running safe? 3.?...4.:?..no ones lookin for a simple solution. Just the best one.

 

[spoolinmp3]

I really challenge anyone on here to say that an FMU is not perfectly legitimate for a low boost setup @ 4psi. Drag, Greddy, HKS, FMAX ect all have been utilizing FMU's on turbo kits with even higher compression motors than ours like vtec's for years.

Now if you want to run 7psi plus boost I would say dont even think about wasting your time on an FMU. If you want I can sell you a microtech for your 4psi setup......but it will be an utter waste of money. Now somebody like GotZoom that plans on running 10 psi of boost or more and running a huge t04b 6o trim turbo, tubular mani ect will need the microtech(laugh)

Really all you will need is a boost gauge. But for saftey atleast get a good egt or a/f gauge. Thats it. So thats 2 gauges

 

[keyserscott]

those are the best.?I love your kit I wanna go stage 1 then upgrade with an intercooler when I get the money. is that the best option?

 

[spoolinmp3]

I understand if one would be paranoid about running a turbo and blowing the motor. There are few on here that have. BUT if you keep a low boost setup there really is no reason to spend the extra money on a computer. If you down the road want to increase boost than run a piggyback like perfs or something more involved like our setup. I think even HI Boost will be offering managment systems for guys that have various turbos from different manufacturers

 

[keyserscott]

So running a low boost kit on an auto would not warrent a piggyback or stand alone?

 

[spoolinmp3]

those are the best.?

I am sorry I really did not understand your question are you refering to FMU's?

I love your kit I wanna go stage 1 then upgrade with an intercooler when I get the money. is that the best option?

You have to ask yourself this. What will you use the car for, how much do you want to spend? And what do you want in a turbo kit.

An intersting tid bit. We have sold plenty of turbos of various stages. And we have never had a stage 1 non intercooled setup have any problems. This is a base lit with I/C and a simple FMU. More people running the I/C versions have had problems. Our stage 1 is a great setup and is very cost effective. I cannot say its your perfect option but a darn good one

 

[spoolinmp3]

Alot of people will tell you that running non-intercooled is plain stupid. My sister has a p5 that we will be running a stage 1 setup soon. If I was not confident in it I would be running an intercooler on it
