engine swap question
 

hi i was wondering if it's possible to easily swap a 1.6 liter engine with a 2.0 liter engine. it's a 2000 protege. thanks.

the motor mounts in our car are different. it *is* possible, but with a little fabrication I believe. there are a few people who have swapped the fs-ze into their 99-00 protege's, but i believe had the 1.8l's to begin with, so no fabbing was neccessary. anyway, it is possible... but requires some work. if you call up corksport, they'd be able to give you better info on this... unless one of the 2.0 people jump in on this thread and either correct me, or add to it. :)

Actually, the motor mounts are the same. The only engine mounting difference between the cars is the bracket from the engine to the No. 3 motor mount (the one located at the timing belt end of the engine). The donor engine should include this bracket. The rest of the hardware should all bolt up, including the 1.6L axles.

The major differences between the engines are the trannies and the wiring. The tranny from a 1.8L will bolt right up to your 1.6L chassis and a 1.8L or 2.0L engine. The 2.0L manual tranny is a G-series, not an F-series like the 1.6L and 1.8L, so you may need a No. 4 motor mount and axles from a 2.0L car (I will check this later), but the 1.8L tranny will work with a 2.0L engine without swapping these parts. The 1.6L tranny will actually work if you install the 1.8L bellhousing (part # F5E1-17-150E) but the cost of this part plus the labor will probably exceed the cost of a good used 1.8L tranny, and the 1.8L has better gearing than the 1.6L.

The wiring is another story. Because the 1.8L/2.0L have several significant electrical differences from the 1.6L (different ignition, VICS, VTCS on the non-MP3 2.0L) you will need the wiring harness and computer that match the donor engine.

thanks for all the help. so if i would swap a 1.8 or a 2.0, what price would i be looking at??

OK, I confirmed some information from my first post. If you use a 2.0L tranny, you WILL need a 2.0L No. 4 motor mount (the one on top of the tranny) and 2.0L axles. Also, the dealer net price on the 1.8L tranny bellhousing is quite reasonable- only $122.50 (retail will be ~$200)- but it will require a partial tranny teardown to install. Depending on labor costs, reusing the 1.6L tranny may be an option, although the 1.8L gearing is still better. :D

The exact cost of this swap is hard to estimate, and depends heavily on the price and availability of used parts in your area. (Forget about using new parts right now- the cost of a new 2.0L shortblock is over $3,300! :eek: ) I'm guessing $800-$1,500 in parts and $500-$1,000 in labor. Add more if you want to upgrade stuff during the swap, such as using an aftermarket clutch or other things like that.

well i've been thinking of swapping an engine in and putting turbo on the swapped engine. i see that a 2.0 is expensive compared to the 1.8. do u think it's worth it? or should i just turbo charge my engine right now? have any of u done an engine swap or turbo charge before? if so, how much improvement is there? sorry for all the questions but thanks for the help.

Actually, the 2.0L engine is not necessarily more expensive than the 1.8L. Both engines are dimensionally identical.

The 2.0L TRANNY is more expensive because it requires more parts to be changed. Either engine will work with either tranny; it's just that the 1.8L tranny is easier to swap because it's the same basic transmission as the 1.6L (an F25M-R), just with a different bellhousing. Therefore, your existing No. 4 engine mount and axles will still work. However, the 2.0L uses the slightly larger, heavier and stronger G15M-R. The F25 will physically bolt on to a 2.0L engine just fine, it's just slightly weaker and may break more easily if you go crazy with the mods. Actually, if you intend to heavily mod the engine, I would go ahead and throw down the extra bucks for a G15, and also buy a set of heavy-duty axles and an LSD from the MSP. :D

Is it worthwhile? That depends. IMHO using a larger engine makes more sense because a bigger engine will usually be more reliable and have a more street-friendly powerband at the same ultimate power output. Also, the F-series 1.8L and 2.0L engines will ALWAYS have more aftermarket support than the 1.6L because speed parts companies usually ignore the smaller, base-model engines in most cars.

thanks for all the help. i'm gonna save up for that 2.0 and turbo charge it. how much does it cost for axles?

Dealer cost for the MSP axles is $274 for the right side and $285 for the left side. Dealer cost for the regular ES/P5 axles is $384 each (the MSP parts are cheaper!) Expect to pay 40% more than this to buy the axles retail from a dealer.

These prices are too freaking expensive IMHO and are a good reason to buy used axles. :D Most yards typically charge $30-$80 per axle, depending on availability. However, since you'll probably be buying an entire engine/tranny/axle/wiring package, you'll probably want to negotiate a price for the whole nine yards. BTW try to get the yard to take your 1.6L parts in trade- they may give you a discount.

Good advice. Then you could get the bigger front brakes too. :D

Engine Swap
 

if your really looking for a good swap, and dont mind getting a used engine, try looking at www.worksport.com, then click on Jspec engines. You can buy an engine that has about 30,000 miles on it but its from japan, which means its got 170hp stock instead of only 130hp which is in the US version. It'll cost you $1950 but its still cheaper then a $3000 new engine. Also you'll have to pay someone to install it, but if you have $5000 lying around then its worth it!

after you're done looking on www.worksport.com you may want to try www.corksport.com LOL

sorry my bad... hehe

I would like to know can a 1.8 engine fit my 2.0 automatic transmission

engine swap question
 

hey, i know this is a old thread so this is a long shot but i cant seem to find any info. so i have a mazda protege 2002 2.0 that was hit by a semi(motor is still good) so i bought a new shell (mazda protege mp3 2001) engine mounts and engine were all the same from the swap part everything was indentical. the engine wiring harness on the new shell doesnt line up correctly. seems a little to short to reach my fuel injectors sensor. Now did i do something wrong along the lines of the swap with the wiring position when i mounted the new motor, or is it a completely different engine harness? If so am I able to swap the engine harness without pulling the engine again? And is it just plug and play or do i have to cut it off at the firewall and rewire it all myself to get the fuel sensors etc,, to reach?
