So let me get this straight...............

[herbieP5]

Is the only apperent problem with putting a turbo on a Pro5 or MP3, with a good amount of boost (10-12 psi), is the fuel managment problem? I am not an expert and wasnt even sure if I was gonna boost my pro5 because of all the complaints about the computer limiting the boost pressure. I am pretty sure the internals of our engine can handle the pressure, So I guess I am starting to lean toward the turbo set up.

Will somebody tell me the + and - of the a kit from spool or flyin?

Also, why cant the ecu be tricked like they do on some honda applications with add ons from companys like cybernation.

I have read a lot of articles on turbos and have been an import enthusiast for a long time, and I find it a shame that there is not something on the market that can make our cars a true boosted beast.

well, I feel like I am rambling now because I am getting frustrated at subaru drivers who are driving arround in their chubby, overweight cars and making fun of true performing cars like the MSP.

I digress...........................................

I doubt our transmaission would like having the HP forced to it at 10-12 PSI.

Our computers aren't Honda computer. They work in an Colsed Loop mode at WOT ignoring all sensor inputs.

transmition problems can be fixed fairly ealily with clutch ugrades and what not, but there is no piggy back systems for our ecu? Or if I get a stage 3 from spool, will I be able to add a new managment system later and turn up the boost, or should I go with a custom turbo. start from scratch and build it up?

I need information on this stuff, I am not afraid to try this stuff, I just gotta know that there is hope.

we will start from the top

unless your talking about the MSP the ecu (PCM) has nothing to do with controling boost.
it controls the pulsing of the injectors and ignition timing.
because it was dedigned for N/A operation there has to be some "fuel enrichment" to handle the needs at low boost up to 7 psi
stock ignition maps on the p5 will handle this. some who own a mp3 might correct me but i believe that the mp3 ecu has a slight advance factor int he ecu.which can cause a problem for the turbo at those pressures unless you are using at least 94 octane and above.

the differences in the two kits are many but for this posts sake it depends on what you want to accomplish. set a goel for power potential and they can both help you. my suggestion would be first make your plan and discuss it with both via phone and they will tell you what they can do. whoever you feel comfortable speaking with then go for ir!

the major problem with the ecu is that honda uses a MAP sensor and with ti a s*** load of honda money to support the aftermarket. our main problem is the MAF. someone posted earlier about ignoring sensors in closed loop. that is not correct. in closed loop the computer will take into a count EVERY sensors inputs and especially OBD2 the o2 sensor for emmisions.
this is probably why the e management system wont work. open loop operation takes into acount TPS and MAF mostly to govern fuel and timing along with pre programed maps for both

and the last statement about no after market support
yes that is true but TRUST me thats not for much longer!!

The MP3 has 3 degress advanced timing which will cuase knock at lower boost levels then a normal protege can sustain.

Aslo the stock ECu will always go for a higher A/F ratio and can pull out 30% of the added fule so you have to trick it into thinking its getting the 14:1 it wants and not the 12:1 your giving it.

Mazda has stated that the Engine block and internals can not sustain more then 10 PSI. Everything would have to be replaced to get more boost.
Aslo the Transmission canot be saved by a clutch, if the power is too much for it then its gonna die. Remeber there is a good damn reason the MAzda 626 was totaly scrapped when going to the 6, the drive drain can't reliably handle the power out of te 3.0L enigne.

The FM kit is the simplest to install and retains the cats for emissions the Spoolin it is more difucult to install as an exhuast shop has to do some of the work, welding, and you junk the main cat for more power.

The WRX is a true performance car, why do you think it went right by you and would still hand and MSP its ass! Subaru has spent YEARs developing that car not just hiring a company a few months ago to slap a turbo on an existing car! Not to mention it was engineered to be 50 hp more then it is here.
Theres no reason to take shots at other cars here. The Protege is the car in question.

I say just use a stand alone E management system that sould work. If im wrong my bad im new to this. Im use to building up them HEAVY CHEVYS but I love imports too. Nothing like beating up on V8s with a 4cyl.

I dont think it ignores ALL of them

 

[chdesign]

in closed loop it does ignor the O2 sensors but it goes to a pre-mapped fuel map but still reads the MAF sensor without knowing how much air is going in then it doesn't know where to start in the given maps.

we need to talk
