Questions about swapping parts engine to engine
Good morning everyone. I totaled my 02 Jetta about a week ago and the mourning is over and the healing process has begun. I have found a couple different cars I can buy but my main question is... Can I swap my turbo, injector's, tune, egr delete, etc to the new car ? Do they have to be the same year or anything special I may not realize before I do this I'd like to keep all the old modifications. The sad thing is the old engine is running fine just had timing belt kit done 10000 miles ago. But those aftermarket parts on there are quite expensive as I'm sure yall know. Thanks in advance.

Do you know if immobilizer was deleted with the tune? As long as you are swapping the turbo etc to another alh they will swap over fine.

ALH was only made until 2003. 04 and 05 mkiv's have a PD engine with engine code BEW.

Other than the tune, you should be able to swap to any VE motor, '02, '03 preferred.
For the tune, assuming it's internal to the ECU, you'd want one the same '02 model with the same ECU part no. for a simple swap. You may be able to get it into a different year, but there will be complications. Unless you're trying to go real low budget, it might be more efficient to just tune the new cars ECU.

I'd be tempted to try and find an ALH that has had a "timing belt event". Swap the motor & the ECU.
My $.02.

Ya I had thought about doing an engine swap with a 99 and a blown motor but I'm not sure how difficult that would be I found 01 real good shape and a clone of my old car. What would be required to swap the ECU / tune to the 01 from my 02 and also how difficult is the engine swap I had a South bend stage 2 cluth so I assume a engine transmission transplant. How much different are 99s to 02s or any other 99 to 03 models in relation to tunes and these mods. Also thanks for the heads up on the 04 I did find one in really good shape but now I will be looking 03 back later. On a side note I have arp head studs would they be a straight swap without pulling head ?

For ECUs, '99.5 Jettas are unique. '00-01 have a different ECU than the '99.5, and the '02-'03 are also different. The big difference between the '01 and '02/3 is the glow plug system. If you use an '02 ECU in an '01 car you'll get a glow plug fault you cannot correct. And I may not remember this right, but I also think the cruise control won't work. You'd be better off having the '01 ECU tuned.

So what do you guys think is easier doing a whole engine trans ecu swap or just change out all the modifications and then have the new ecu tuned ? I know my trans and clutch have been upgraded I would like to just swap the whole thing out and save the other engine and trans but honestly how long do y'all think that would take I have pretty much all tools needed minus vw special tools. Is it a weekend job ? And if I put the whole engine and trans in the new car with the matching ecu is there anything else left to do ?

Will your tuner disable the upgrade to the "old" ECU and upgrade your "new" ECU? That is the easiest route in my opinion.

BobnOH September 21st, 2017 13:34

If the car you buy has the same ECU part no. as your '02, it will drop right in.
I did some searching, the ECU for an '02 manual TDI and an '03 manual TDI are both 03890612FD. That scenario, your chipped unit would drop right in.

To change the engine and transmission doesn't require any special tools. But, you will need more than a set of boxed-end metric wrenches, screw drivers, etc.

I'm sure everyone that has swapped engines have a sequence they follow, give or take a step or two.

With a good jack (meaning size mostly) and cherry picker, you should be able to drop the engine out the bottom in a few hours. Disconnecting wiring, hoses, axles, shifting cables, exhaust, etc., is the most time consuming, in my opinion.

I use a "home-made" vacuum system to suck out coolant as I remove hoses to save the coolant, but mostly to reduce the mess. The vast majority of connectors will only plug-in one location or their length/location makes it quite obvious where they go when going back together.

(Different Engine) > It recently took me about 5 days to swap a 2.0T Gasser engine in a 2008 VW EOS, scattered out over more than two weeks (we seniors work at our on pace). That engine had loads and loads of wiring connectors, hoses, pipes, etc........ everything went out the bottom without having to remove the hood.

Ol'Rattler September 22nd, 2017 23:24

At least you didn't take it out the bottom because you had a senior moment and forgot that the car has a hood that opens.:D "Damn Sam. It must have taken me 3 weeks to change the air filter".

Congrats on the retirement. With retirement I found that by not drinking I have a lot more time to devote to important things but there is still not enough time in the day..........
