ok.. so here is what i have and ill get to my question in a minute

turbo p5/msp

CAR STATS:
MSP STOCK ECU ( no mpi tuner on it at the moment )
STOCK injectors
STOCK fuel pump
MODIFIED HEAD ( port and polish.. stock internals)
FMIC
GREDDY type r bov
downpipe being built at the moment
2.5 exhaust to tanabe ( straight through
AEM wide band ( it reads 17.0 at start up, 10 under boost )


issues: NO power.. like.. it makes all the im gonna get up and take off but nothing... at 60 mph i can have the pedal to the floor and it bearly makes it to 70... just runs like crap . has no power under full boost.. and is burning fuel like no other.. was having valve issues... had them fixed.. checked timing 4 times.. we did the timing belt twice to make sure it wasnt off by even a tooth. thought it was an injector issue... replaced them, fuel pump, fuel lines fuel rail and now as of today fuel pump, maf been replaced 3 times.. relocated the maf to 4 different places... swapped out bov's new vacum lines, hell new alt not that it has anything to do with it. changed the oil 3 time... some sediment in their.. not a bearing.. but a shaving from the pnp and milling of the head... checked the rotating assembly for any issues.. bearings adn all .. tehy are good... another issue the car is having is a heat issue.. i was coming back from topeaka to junction city where i live. and the car was running hot... so i stopped and checked the fluids... they were good... checked the plugs.. they were bad.. again... all blackened and the tips were toast.. so i got new ones.. threw them in and bam.. they went bad changed them out from stock p5 to stock msp plugs.. same issue.. went one step colder... same issue.. so now... im buying a completed new motor... stock... just gonna slap the turbo on it and call it a day ( after it gets rebuilt.... anyone even have a clue what is wrong with the motor?? should i just blow it up and call it a day? i'm really frustrated with my mazda... i love it but... its a hassle not to be able to drive it

bump..???

well.. i know some one has this issue.. or has had it before... any ideas guys? maybe i have this posted in the wrong spot?

are those stock p5 injectors and fuel pump or msp injectors

[orng1]

They are the same or similar injectors, I think the MSP injectors just have a different spray angle.

It's burning fuel like crazy, is it smoking? Recheck all your couplers and clamps. I've had that problem a few times.

[slowtege5]

Yeah i could only get 5 psi out of my injectors but i had to upgrade the fuel pump to do so, also had to tune it!

The P5 and MSP injectors are the same. You need some type of EMS.ie SS afc , AEM fic or go standalone. BTW did you get the fax.
