ok thank you aries

new bp = Sweetly easy swap....

If your planning on using the stock axle and half-shaft with the stock F-series Trans (what i did) your going to have to either modify the half-shaft...or buy a new one that is 1/2 an inch shorter.


At first i modified the half-shaft... I welded an extra 1" to the right side of the mount and extended out the hole, then I Die-Ground the other 2 holes over right and dremeled new bolt landings...

Then My pass- outer most CV tore in jan and it toasted the bearing...so i got a new outer axle and had a shop match me up the half-shaft... I think it's from a Protege that had a F-series and a BP....So if you get that info you'd be SET...


By yourself with the right tools, a picker and a calm head it's an easssszzzzzzz swap...

only thing you have todo is unplug the fuel-injector harness from the B6 and put it onto the BP...Then plug in ALLLLL the sensors from the B6 and Zip-Tie them to somewhere...That just prevents the ECU from throwing a code and running in Safe-mode...

Although I still get a ghost code in 4th/5th cruising with little to no throttle for periods of time...

ahh awesome, but everything else goes right up. do we use the bp ecu or the b6? thanks for the info ill do some searchin on that jack-shaft see if i can find anything. thanks cy

i'm running a B6 ecu...

I image i'd make another 20hp if i ran the BP...just because of the difference in the fuel MAPS....

But on open loop really all 4cyl motors "Could" run on the SAME exact ECU...the only difference is the pre-programmed injector and ignition timing, and AFR...

which is why we have Megasquirt, AEM, Greddy, etc Engine management units

ahh ya, are you running any kind of engine management? if id bore the block and get performance cams id have to get some kind of management correct?

i got a question...what u mean by connecting all the sensors and ziptieing them somewhere? do u mean the ones that are hooked up to the BP ziptie off? i was just curious cuz imma be doin the swap here in a couple months hopefully

He means to leave the sensors and solenoids plugged in - the new BP uses less solenoids in some respect.

ok thats what i figured he meant but i figured id ask, thx

im plannin to do this swap as well, are you runnin the bp ecu aries? lots of splicing i bet.

I'm currently running the B6 EVERYTHING....from Distro to ECU only thing BP is the complete engine...

and it's making alot more power...as expected .... because it's melting the aftermarket OEM Clutch i have.... If i do like 5 or 6 - 1st gear to 2nd gear burnouts, letting the clutch slip down as the tirespeed comes up....it glazes the clutch and i have to cruise easy for like 500K.....

Aftermarket Stage 3 clutch here i come

awesome i cant wait to get the swap done in my car. and i already have a stage 2 spec clutch kit from my turbo set up so that whole issue is bypassed

ahh awesome thanks aries. since you have it bp ecu wired up, do you notice a big difference with that compared to the b6ecu running? my car is basically ready for the swap just need to find a good engine for a good price kinda hard with the shipping.
