MX3 BP swap

[Jho]

well its not done, the shop had a few probs with my car going before customers that were on a 3month wait, haha, well its going to be done on Monday, just have to get a wiring diagram from Mazda, the boss man wants to make it look better than a factory job, so i'll let him, i get it all for under $1000


BP Motor/tranny/ecu everything= Free
new stage one axles= $168.57
gasket material/o-rings=$21.39
labor= $800


he is also gonna fix my pacesetter exhaust from my pro and make it fit the mx as well as building me a cat delete and tuning the car, this should be a mean beast.

Intake, Header, Exhaust, BP, MSD Coil, RPMz dizzy, NGK plugs and wires they are guessing, 140ish at the wheels, this is the first Mazda BP swap in my area too, my car is one of two mazdas that are customers at the shop, and the other doesnt have pistons. also anyone know of a place that i can find some 60-80duro motor mount inserts to replace the rubbery stock ones thanks

Sounds like your getting hooked up. That should be nice.

I don't know the duro of the ES poly lower engine mount inserts, but I've been using them for over a year now, and am very happy with them. Some people have complained of the front one not working, and having to get an escort mount to make it work. Mine fit just fine, just giving you a heads up.

I got them from ZXTuner: http://www.zx2racing.com/store/close...d=192&offset=0

w/o different internals or cams/cam gears you wont see 140whp.

looks like a good setup so far.

still no power to ECU whats the deal?? any ideas guys, anything commonly overlooked on the swap?

[tunerguy]

Ok so i still have no car, i found a 1993 MX3 V6 5speed and i am going to steal the chassis electrical harness to it. WIll that be compatable with the BP harness or will i still be stuck

The MX-3 harness is different than the BP harness.

I read somewhere that it is nearly plug and play, what MX3 is nearly plug and play with the bp?? What do i need to do on the 1995 MX3 to make the BP electrical work?? the car turns over but no ECU power what do i change?

I'd use the harness and ECU that matches the engine you are using.

It's only nearly plug and play if you have a 93 or older mx3 SOHC 1.6. The 95 DOHC 1.6 harness is different. Even with an older sohc 1.6 harness you would need to run wires if you want VICS.

well i found what my problem was, the reverse light was some how shorting out and burning the 10A engine fuse, however now we cant get the fuel pump to turn on so we are going to create a relay for it in the rear of the car, mind you that the fuel inj relay in the front of the car does click when i turn the key, so there is a prob some where in between, what wires do i need to run or swap for the 1995DOHC MX to make the BP work correctly, i hear rumor of running a wire for vics, did the DOHC B6 not have that feature?

[tunerguy]

THE BP IS ALIVE!!! finally today, i cleaned out the car, wired the fuel pump relay and then installed the intake, changed the distributor cap, and cleaned up the wiring mess, tomorrow morn they are going to weld the exhaust and then its off to the races

also what would cause my temp gauge to go through the roof before the motor even started

A failed temp guage sending unit.

its like a 10 dollar sensor from the dealer or something cheap like that. Vato zone probably has one.

Yeah, you should be able to pick one up at the local parts store.
