#1858 of 1867 96 metro engine into a 92 metro
Jun 07, 2012 (5:49 pm)
I have a 92 metro with a bad engine, and a friend with a 96 engine. What kind of issues will I encounter making this swap?

You may not realize that there were at least five different motors used in the 1992 Metro, and at least 3 different motors used in the 1996 Metro.
Basically, the Metro was made with a 3 cylinder, 993cc motor (called the base model and the LSI); or with a 3 cylinder 993cc motor which was designed for more extreme fuel economy (called the XFI, which was not made in 1996); and was also made with a 4 cylinder, 1.3 liter motor. There were also differences in the motor which was used with a manual tranmsission; compared with the motor used with an automatic transmission. And there were difference in motors which were made to meet 49 state emission requirements; compared to motors which were made to meet California emission requirements.
So you first need to make sure that both engines have the same number of cylinders; and use the same type of transmission. You then have to make sure the 1992 vehicle is not an XFI model (XFIs have an all black rear bumper; while base models and LSIs have a two color rear bumper).. But you might be able to get by if both vehicles do not have the same class of emission equipment.
The 1996 vehicles used a totally different electronic engine control system (called OBDII) which would not be practical to adapt to a 1992 vehicle. So you would need to use the 1992 intake manifold, throttle body, distributor, ignition coil, igniter, computer, and wiring harness with the 1996 engine. These parts should be directly interchangeable. There are one or two sensors on the 1996 motor which are not used on the 1992 motor; so they would have to be left disconnected (and preferably removed). Both motors in both years use the same spark plug and the same plug gap.
The 3 and 4 cylinder motors use different model clutches; but the 1992 and 1996 model clutch does not change with the years for each engine type.
The automatic transmission uses the same overhaul kit for both engine sizes and both years (though that does not necessarily mean that the transmissions are entirely the same).
This should be a straighforward swap; providing the engines are the same type, and you folow all the steps listed here.
If you post additional feedback; please list the engine size and transmission type. Also get the emission specification information, from the emission label on the underside of the hood of each car. Thank You.

Thank-you, you have been very helpful. I do know both engines are the typical 993cc version and they both have the 5-spd tranny. I will get the emission info and post it, if you could look at that, I would appreciate it very much.

Thank you for the updated details. I would also recommend using the 1992 oil pan; as that eliminates the crankshaft position sensor; which will not be used, and which protrudes from the 1996 pan.
At the bottom of the text on the underhood emission label; there is a note which reads something like "This vehicle conforms to all US emission regulations for 1996 model year new motor vehicles sold in the state of California."
This is where the distinction between California and 49 state emissions can be found.

Before you start switching the motor; I would STRONGLY urge you to run a compression test on the 1996 motor. The stock compression on this motor is 195 psi. The minimum allowable limit is 165 psi. There also must not be more than 10% difference between the lowest and highest cylinder pressures.
All too many attractive looking Metro engines have compression that is out of specs. This is the result of driving the car too slowly in 4th or 5th gear under load (due to not downshifting) or mixing brands of oil; either when the oil and filter are changed, or when oil is added betwen changes; or running at high speed, accelerating hard or climbing steep grades before the motor has warmed up to normal operating temperature; or using unsuitable spark plugs or low octane fuel in what is basically a highly tuned motor.

Thank you zaken1 for your help on Venza vs. LexusRX350.

You're welcome; but from this unusual location which you chose to contact me; it seems like you may be having difficulty navigating around the Edmunds website (either that; or you are an avid tourist and explorer). I mentinon this because when someone wishes to express appreciation for the help they have received with their "answers" question; the normal way to do that is to log onto the original question (which you can find at http://answers.edmunds.com/question-Are-Toyota-Venza-Lexus-RX-350-vehicles-15983- - 9.aspx) go to the answer you feel was most helpful; and click the "accept as best answer" button. This awards points to the person who wrote that answer. Those points determine our rankings on the site. It is also customary to click the "thumbs up" button under the answer you like; as that awards more points. But I still appreciate your going out of your way to contact me and express appreciation!!!
P.S. I was born in New York (But I have lived in California since 1952).

I just went through this issue with a '94 Metro 1.0L.
The unused pin is A, and so B and C are on that same side of the connector. D, E, and F are on the opposite side, D is adjacent to A, etc. When you do jump from D to E you should notice the timing will retard, then set the timing to 5 BTDC and remove the jump. The timing will jump up to about 7-0 BTDC.

Hi zaken1: I find your recommendations to be very insightful/helpful. I have had the exact same issue with the exact same model/year car as tvmogul. I do have one question with regards to your item #8 (8> If someone has moved the distributor position; in an ill advised effort to change the timing; it could cause this problem. The ignition timing cannot be adjusted on this motor; but moving the distributor position will change the rotor air gap; which will cause the motor to cut out on acceleration.) I don't know the history of my '98 Metro and can only guess that this may have been done at some point before I bought the car 3 months ago. Is there a way to check for the correct rotor air gap and how can the distributor be reset to the correct factory preset position?
I have no access to an engine analyzer or even a tach meter, but I can take the car into a mechanic who can reset the distributor if you can provide the needed specs. Thanks, dgarr

I guess since you are asking you are missing diagram inside hood. Mine is missing also but, I found a factory service manual. Check on amazon and eBay for used manual. I paid $45.00 for a good used manual. If restoring you will probably need. I will dig out my manual and try to make copy of routing. I am not sure how to get it to you though. I don't see how to do a file attachment.
