I got an ELM based scantool and interfaced the ECU with an old laptop. Right now i am just reading stuff from the ECU - once i figure out how to do two way communication i may be able to adjust parameters like fuel trim, timing advance etc.

Just to clear up any confusion -
The swap info is for swapping a new gen BP (95-98 protege) into a DOHC (94-95) mx3 (both ATX).

Need to use the mounts from B6 -

Two ways to hook it up-
1) Use the B6DE ECU & harness (engine harness, injector harness, alternator/fusebox harness) - almost everything plugs in - use o2 sensor from B6DE - some of the solenoids may not match up with the connectors - can either splice in the connectors from BP or use B6 Solenoids (BP has 1 FPR solenoid and B6 has 2 - so need to get that solenoid and plug it into the harness to avoid codes)

2)Use the BP harness and ECU - the dash connectors are different - so need to get mx-3 connectors and splice it into the BP harness - the wire colors are given in the table below - Some wires are in the old trans computer connectors - dont need that computer anymore - unplug the connector and splice away. The connector that goes to the fuse box (under the hood) is different - get mx-3 connector and and splice it - same color wires - there will be an extra Black/Red wire - the old transmission harness is not needed anymore (because BP has integrated transmission harness) - separate the Black/Red and Black/Blue wires from the old tranny harness and splice it with the same color wires in the new harness (Can cut and discard rest of the harness). If you get the OBDII connector from the protege - you can splice some wires to that connector and hook up OBDII scanners or a laptop computer (with some additional hardware).

I'm about to do the same thing with my 93 B6 SOHC. I wasnt planning on doing in until the spring, but I wound up NEEDING an engine last week when some idiot stipped a plug-hole and ruined the head.....that and the engine was already leaking oil and the last owner screwd up the timing bet...a real mess. Anyway my only concern at this poin is the transmission/clutch situation. Can I use my fm25-r or do I have to get a gm25? And If I stick with the F can I use my existing clutch or do I have to by a protege clutch. Please help ASAP cause I need this done by the end of the week. Thanks.

Your swap is not the same as mine - you have an SOHC engine and mine was a DOHC - the wiring is different. I also used a BP from a 95 protege and its different from a 90-94 protege. I beleive you can keep the mx-3 tranny but you will have to get the BP flywheel and clutch (i might be wrong on this) - the whole (90-94) bp swap into SOHC topic has been discussed to death and beyond - so you will find a lot of info if you go thru some of the old posts and faqs.

Yeah I read a few topics about the SOHC BP swap but they all get kinda vauge around the Tranny issue. Also this is the only swap topic I can even post in. I just thought some one going through here might know for sure what my options are. I've heard you can, then I heard you can't, that you need the G tranny. I'm just trying to find someone that has made this swap with the SOHC and what they did with thier tranny situation. BTW hows the BP workin out for you?

There are a DOZENS of different 4-cyl swap guides. You cant tell me that this info isnt a few clicks away. Now you have gone and junked up this man's topic about a completley different swap than yours.

You CAN keep your F-series tranny, but you must use your current (MX-3) axles & clutch & flywheel if you do.

If you decide to upgrade to the G-Series tranny, you will need new axles, jackshaft, clutch, flywheel, and top tranny bracket.
All from a 90-94 Protege LX.

I have had my F-series and my BP-swap for a few years now and I drive the hell out of it with no problems.

Sorry, I wasnt trying to junk up anyones topic. Yes there are dozens of guides out there but they dont all agree. I've read that I HAVE to use the G tranny with GS Axels, I've read that if I use the F tranny I have to use a Protege Clutch. It really confusing. This isnt some Honda swap that is more or less plug and play... or atleast the internet would make you think its not. I needed to know from someone who actually did the swap. IF you know a better place than MX-3.com to find that, let me know. And as I said earlier the only reason I posted in this swap topic was because I <b>can't</b> post in any other swap topic (which is stupid IMO because now I've gone and pissed people off) Anyways I got the answer I'm looking for so I'm done and gone. Thanks for your help.

Hey WICKED SWEET POST...
You need to condense all the info into 1 post and get this FAQ'd

I'm going 1.6L DOHC to the New Gen BP...
I will be getting this swap done at a shop because I don't have the garage space anymore...I'm gonna help the guy along as much as i can...

A Picture's worth a 1000 words.... could you take and post some pics of the installed motor..In particular I'd be looking for the locations of the coolant lines and electrical connections.. aswell as any splices into the 1.6L harness...

Also a would it not be possible to wire in the 1.8L o2 sensor?? my 1.6 one is definetly shot and i get a new one with this 60K motor...

I will try to take some pics if it stops raining here (its been raining for 3 days now and its cold too).

If you use 1.6 Harness & ECU-
Coolant lines and electrical connectors pretty much go in the same place. You will have to take a fpr solenoid from the 1.6 and leave it plugged in (B6 uses 2 fpr solenoids and bp uses 1). You may have to switch the EGR solenoid connectors as well. Use the B6 injector harness. Bp has an extra crank sensor - you can leave it unplugged. Use the B6 harness that goes to the alternator, starter etc. You can use the BP's 4 wire o2 sensor - just splice the 4 th wire to battery ground (not chassis ground). Dont remove any vaccum lines - the B6 has a long vaccum hose going from the airbox to one of the EGR solenoids - you wont need it - you can just plug the hole in the airbox.

Enjoy the 125hp.....

Are you planning on boosting ?

I'm making an adapter for a t3 turbo from 6"x1' roundstock..Something like what homemadeturbo does..but CNC'd...
5 threaded holes for the studs to the manifold and 4 for the turbo with the inlet hole cut out and then tapered up..

There will probably be a crown but i have to measure the flange on the old primary cat to get the right measurement

ariesdude · Post by **ariesdude** » November 18th, 2006, 1:49 pm

Is definitely in the plans - probably next summer. I am planning on boosting just 3-4psi (because i want to keep the auto) and i just want some low end torque.

Cy · Post by Cy » December 8th, 2006, 4:37 pm

well the motors in... and running like garbage... i think i have to switch a few parts from the old motor to this one...

The biggest issue is that it mis-fires like Crazy... lightly on the throttle it's not bad up to 3500... but on the throttle in almost any rpm and it won't crank past 3500rpm...
