    Re: How is the new engine, working all right?

    Went with a used 2002 engine from Double 02 Salvage. Car ran great, tons of torque and acceleration. Even smoked the tires in first gear, and can chirp them into second! But on my first trip over 10 min, the car overheats. After trying everything, it wound up over at a top BMW mechanic in Canoga Park, CA.

    He determined that there were some clogged passages in the head, but after hot tanking, it was determined that corrosion had damaged the head beyond repair. Bruce, the mechanic, contacted Double 02 Salvage, and they've agreed to send a replacement head.

    It's been a few weeks, and I'm still waiting for the car to come back. But I'm hopeful!

    How is the new engine, working all right?

    How did your project turn out? Also, can you post some photos?

    It's not running yet, but I'm very happy with the way everything is going. I did post a couple of photos here some time back. I don't have a final write-up, but some remarks here and there. It's going to be very cool, I think, and to me it is a very logical engine choice, as it still looks "old school" with the aluminum cam cover and intake and the header. I'm working on wiring now, with most of the '02 wiring coming out and the 318 replacing it, situating the fuse box and integrating all the engine to general wiring systems to instruments and body of the '02. I have rack and pinion steering with a MOMO wheel as result of the swap, so I'm anxious to feel that, and a five speed, and a limited slip. I need wheels and a suspension rebuild. It takes time and...

    Jim --

    Do you have the m-42 swap written up anywhere? I'd love to see some pics and hear some details on any particular problems you had.

    Re: Dropping a 320i engine into a 2002 - not easy

    I had been having a hard time finding any sort of 2002 engine. All the major places that carry them were out of stock. I was recently told about Double 02 Salvage in Hayward, California. I called them up, and they had used 2002 engines, so I ordered one, and it arrived in a couple of days.

    Switching parts over right now, so it should be up and running in a few days.

    Yes, this is a one owner 1970 2002, with everything original, and since it's been in California since new, there's no rust on it. It was discovered in the original owner's garage, where it had been sitting since 1987.

    Thanks for everyone's help and suggestions.

    Re: Dropping a 320i engine into a 2002 - not easy

    As Jim S said, no transplant is easy. Back to your 2002: is it in good enough condition and mostly stock so that some future collector might want it in close to 100% original condition should you decide to sell? Invariably, as the years go by, modified cars are worth less than stock ones. Why not buy a new/rebuilt 2002 engine from Metric Mechanic or a specialist like that? Good luck, and enjoy the best sedan ever designed.

    You would want a low pressure pump if you keep

    carbs. The English car guys have low pressure electric pumps available.

    Re: Dropping a 320i engine into a 2002

    Thanks Jim - is there any other things to convert beyond Oil pan, dip stick, and fuel pump - speaking of which - how'd you do the pump? The 320i's pump was part of the gas tank insert? How do you power it? Where to wire from?

    Re: Dropping a 320i engine into a 2002

    Allow me to add a subtle point relative to the oil pan change. The dipstick tube is shorter on the 320i, but the dipstick is the same as an 02. So use the dipstick tube from the 02. If the 320i tube is used, there will not be enough oil in the 02 pan at the stick full mark because the stick will set lower in the sump.

    I have a 320i intake converted to high pressure EFI. Laer, while crusin the parts yard, I found an unadulterated 320i that had the correct support bracked for the dipstick tube. The tube also mated to the bracket nicely. I set the tube in place on the 02 and set the stick. The oil level read overfull. So I compared the tube lengths discovered the differences. I used the 02 tube.

    Re: 320i engine into a 2002 sounds reasonable...

    Thanks for the tips. I had lined up a 73 2002 motor this weekend, but that deal fell though, and I'm out looking for another motor.
    If I did go with the 320i motor, it w ould be simply because they're easy to fine, and the place that has them (Bavarian Motor parts in Rancho Cordova) has such a great warranty, I can't overlook that option. I'd only be getting the motor, no tranny or anything else. I had already counted on swapping the fuel injection for the carb, and swapping oil pans is easy to do. It's going into my mechanic's shop, so he has tools, hoists, etc.
    As long as motor mounts line up, and the tranny is compatible, I may just give it a try.

    Re: Dropping a 320i engine into a 2002

    I am in the middle of replacing my 75 2002 M10 with a 77 320i M10 engine...

    Oil pan - 320i oil pan is deeper, must exchange

    fuel pump - 320i head is not drilled for mechanical pump, I am investigating an electric pump placed at rear of car

    intake with carb - looks like a perfect fit. Opted out of using the fuel injection because it requires stronger lines leader from gas tank that the 02 came equiped with.

    Here are some pix of my process thus far...

    320i engine into a 2002 sounds reasonable...

    I see your position. Do consider that no swap is as simple as it sounds, all things considered. The radiator should be fine, trans, too, assuming no issues with mounts. Check the fit with the oilpan and the steering clearance, but they are so similar, I would think it should work. The e21 has rack and pinion rather than the steering box. Fuel pump and filter need to be changed, but an e30 in tank pump/sender unit fits the 'o2 sender unit hole, so that should be easy. I would run new hard lines under the car to eliminate the plastic lines through the cabin for safety. Lower the pick-up about an inch.

    Does the 320 engine come as a parts car? Trans? Electicals? Mounts?
    I'm nearly finished with a '91 m42 (same basic 4 cylinder, but from there it is radically different) into my '76 '02, and it's NOT been piece of cake, but it will be sweet when done. Many modifications and fabrications, but it's still all BMW and very clean. I'm down to finishing touches on the coolant and vacuum hoses, wiring, fuel hoses, intake, and exhaust. I did replace all gaskets, seal, fabricated mounts, hoses, 5 speed trans and modified linkage, new 318is radiator, auxilary electric cooling fan, custom driveshaft from BMW pieces, e21 rack and pinion swap, and a few more troubles.

    Your swap should be much easier since many items are compatible, such as the radiator and trans (I'd want a 5 speed), and maybe the same driveshaft, but still, you will be looking at several dollars more than $750 by the time you've done the fuel, exhaust, new hoses, and anything else not included with the e21 engine. Don't be surprised if you spend closer to $1500 by the time you are finished. Got an engine hoist? Decent garage? DIY or having it done? Do it really well if you want to drive it safely or sell it later. Don't cut any corners on details or quality. You wouldn't believe the number of pieces from other years and models of bimmers you can access. I've had great help from an excellent BMW parts counter man and a friend who parts e30's for a business, forums, and the occasional search of RealOEM to examine parts diagrams for any year and model. Very helpful. Go for it! Let us know how it goes. Good luck. Jim

    Dropping a 320i engine into a 2002

    How difficult would it be to drop a 320i engine into my 1970 2002? Both 2 liter engines. Do they have the same external dimensions? Can I remove the furl injection set up on my old engine, and swap the carb over to the 320i engine? What about the fuel pump?

    If anyone's ever done this swap before, I'd love to hear how it worked out.

    For those who are wondering why: the engine is seized in my '02, and I can get a nice used 320i engine, with a 2 year warranty, for $750. I can't rebuild my '02 engine for that price!
