thought the escorts were from 91-95.

this is great info alot of people need. this should definetly be in the 4cly faq.

thanx

for 94+, you will need the coil/ignitor. whether it be from the bp car or an msd setup.

the "3rd" axle is also called a jack-shaft, half-shaft, etc. it's the axle that bolts to the back of the block and goes into the passenger side of the tranny and the passenger side cv axle connects to this.

And, 94+ MX-3's have electronic speedometers.

The BP did not.

i second the faq suggestion, great work marlon you answered all my questions

now, if only we could get the exact same way of info for the BPT and B6T and the KLZE and everything else....the BPT should be exactly the same info right? or will you need a stronger tranny and clutch on all years?

Hey this is what i was looking for earlier, haha thanks. One more question, does the BP use the same alternator as a b6? I would like to get a stronger one and was wondering if i should take this out of a parts car when i get the chance?

i think it's the same
if u want a more powerful one get one from the v6 and swap pullys
search for more info

question about the 92-93 info.
do you know if the b6 tranny bolts directly up? will there be a few bolt holes left unfilled? are you sure that the sotck mx-3 clutch will work with the engine? i thought there was a differnet amount of teeth...
Then again i think alot and all i end up with is a headache, any help info would be great.

the stock sohc tranny works but u need to your your stock clutch and flywheel off of the sohc

so basicly all yu do is unplug everything from your sohc and just put in the dohc with tranny and flywheel and cluch then just plug every thing back on.Like a\c piping and eveything else.
and
then unplug the ecu and plug in the dohc ecu.

also one more question if the engine is a 94 does the ecu have to be from the 94. or can the ecu interchange from year and model(like protege to ford )

thanx

ok sounds simple enough. any other tips ?

Good info... I'm doing research before I do this swap.

I've got a 96 RS and I want to throw in a BPT.

I have a few questions tho if anyone can answer this:

94+ with stock tranny
Parts needed: BP engine, harness and ecu

94+ with bp tranny
Parts needed: BP engine, ecu, harness, tranny, clutch, flywheel, 3 axels and mounting bracket for the tranny under battery tray

What would be the advantage of throwing in the BP tranny over using stock?

Also there is talk about the "GTX" and "GTR" engines... what is the difference between the two?

Would there be an advantage to getting J-SPEC engine over a North American one?

Thanks.

you're confusing two different motors. the bpt was never released in n. america. if you're wanting the american engine, you're talking about the b6t. if in fact you do want the bpt, the 1.8 turbo engine, there are two versions. both are very good motors, but unless you get a very good deal, i wouldn't waste my money on the gt-r.

as for the tranny, you want to use the bp tranny because it was built to handle more power.
