BPT and B6 Tranny, Mounts, questions.

I know this is probably a repost but I wanted to know a couple things. Before I ask, yes I did use the search fuction and all I catch are things close to the answers but not close enough. Ok. Question number one, I know a B6 Tranny can't hold the power of a BP. Does the Tranny bolt up to the BP this way I can keep the same CV axle setup? I will be looking towards getting stage 2 axles at corksport if it is and as for the tranny, I'll probably bring it in for work. Now the mounts. When the swap is done do all the motor mounts line in? I don't want to get excited and buy the motor and not be ready for the setup. I want to keep it at a one to two day project. Another if the tranny mounts in question. Are the internals swapable from the BP trannys? Thanks for your time peoples. Hopefully I lose my newbie status. I was a KA-T nissan person before and new many answers lol. Stock 240sx block with a turbo lmao.

NM about the tranny, I am going protege tranny and Hybrid axleshafts. But yes questions about any mounts needing to get moved or how about AC lines?

Let me save you the trouble.. This will NOT be a one or two day project. There will always be something that you dont forsee and youll have to wait for..

Making up intercooler piping and modifying the front bumper.. it takes a while.

And save your money on the axels.. Stage 2 is needlessly expensive.. stock ones will do just fine.. Youll blow the diff in the tranny LONG before the axels give out. If you get anything.. Get a phantom grip LSD first.

Anyway, The mount situation.. The one on the passanger side can be the mx-3 one... with the others it really depends on what transmission you have. With mine I have G series tranny that came out of a early 95 protege, its a weird model that even confused the people at the mazda dealer. Anyway, The front tranny mount is an mx-3 mount inside a 95 protege bracket.. The driver side mount and bracket came from a protege. You might have to go back and forth from a junkyard a little. Id say your best bet is to get that mount along with the transmission. As for the rear mount and bracket. Im using the mx-3 one off the b6 tranny. Had to cut a little piece out of it to make it fit but it works just fine. Alot of stuff is on the fly with this stuff. So be prepared to do alot of running back and forth to places.. Youll need another car and a full tank of gas

OHHH and make absloutely sure you get the flywheel out of the same car you got the tranny from just to save yourself the agravation.. You cant use the gtx clutch and flywheel just so you know.

OMG lol thank you so much, finally somewhat of an answer I was looking for. I have to thank you so much for sharing that, now what your saying is the biggest thing I have to do is the mounting brackets off a protege. By the way is a 95 Protege a NA BP and has a G series transmission. Yea basically I am trying to avoid running around by saving up money for all the stuff I need, but the turboing is gonna be a later thing. I just wanna get a dang BP in there from a junk yard with somewhat good miles meaning better than the 160,000 on my stock BP lol. And do the Axles have to be custom. What did you get, or does MX-3 Axles fit that tranny and that tranny isn't shifted slightly?

The reason for an NA BP is so that I can forget about difficulties and make up piping while having a driveable car. Also this way I can get an engoine for a better price and when it comes time, build up the block and it will cost less than a GTR but be as good if built right. Plus corksport has the gtr rods and j-spec intake cam.

Basically any place can do this.. Get the axels out of the car that the tranny comes from and then just get them to switch over to the mx-3 ends. Unlike the mx-3 the protege axels have a half shaft that bolts to the back of the engine. Where the mx-3 just has one long shaft going right to the wheel.

As for what tranny to get. It has to be off a bp series engine. I heard 90-94 protege lx 1.8 and the ford escort gt also has the same gearbox, apparently some kia has the same one also but god knows what model.. Im too lazy to look it up. If youre buying the bp from a junkyard.. Just buy everything out of that car. Buy the whole engine and gearbox.. and get the ecu.. and you might want to get the wiring harness too just for the sake of plug and play. I know that I modified my mx3 harness to work with the bpt and the gtx ecu. It didnt take much it was just figuring out what needed to be changed was the hard part.

What year is your mx anyway?

My MX3 is a 95 B6 with dual overhead cams. I was thinking about turboing the B6 but I wanted to go a bit bigger. Do I have to change the shifter linkage and what parts will I have to strip out of the Protege LX. I also heard later than 95 has a 1.8 but I don't know if that is a BP series.

Franko · Post by **Franko** » April 3rd, 2006, 8:31 pm

90-94 is the good bp series.. There are later bp's I believe but they arent as good. The shifter linkage is the same, and I think youll be best to get the whole harness with that engine since your harness is way too different than the bp series.

Awsome, yeah I am gonna try attempting to knock out the project in two days. So that seams like my answers for that. Before I still don't know what you mean with the whole mounting brackets, this is way different that what I am used to, I am used to doing all RWD cars lol. But are you saying you had to do more moding cause of your tranny model and is the earlier tranny model more of a direct mount and from what you've seen which tranny is stronger? So if I go with your setup, can you help me a little bit with the eplanation on the setup of the mounts. Plus I found out switching the ends on axles aren't hard so I can do that all myself. And the intermediat shaft, the motor comes with a mounting area for that???

P.S. Thanks dude so far you are a real big help. This is gonna be my first time beefing up a front wheel drive car. Not used to much yet. Lol belts are irritating and thats about it. But really, you are pretty awsome. Thx for all the pointers so far, I'm gonna print this sucker up soon and start getting to work on this craziness.

here's what you need:

front motor mount: protege bracket (bolts to tranny)
mx-3 motor mount (round rubber thing that bolts to car)

driver side mount: all protege

passenger side mount: the part that bolts to the car comes from the mx-3
the part that bolts to the engine is from the protege

rear trannt mount: protege or mx-3 mount will work (round rubber that bolts to car)
protege bracket (bolts to tranny)

the axles from the protege will work, i didn't need to change any axle ends. you also need the jack shaft. the motor has 3 tapped holes in the block so you can mount the intermediate shaft. you will have to get those 3 bolts too. maybe the bolts from the RS motor will work.

also make sure that your tranny comes with the metal clutch line. i had to order one because it is different than the MX-3 one.

the biggest pain for me was getting the axles separated from the tranny. good luck with the swap...it's totally worth it.

Phantom Grips are trouble and are a waste of money. Preloading the spidergears like that will cause the gears to break faster than leaving it stock. And I've known MANY people that have used them and swear they'll never go that route again (one is a DSM shop owner who used to be all about Phantom Grips untill he used them for a while).

Lol this thing is old but thanks pal you did add some good info for me. Cross your fingers that I get it in when I purchase the motor in this month. It's hopefully going to be the BPT from the GTR. One of the guys I called have one in stock.
