mkIIIs weigh a fair bit, but i know from hauling a ton of junk in my rabbit that the 1.6L TD is sufficient to move that amount of weight.
i'd like to put that 1.6L TD into a mkIII (giles pump later to wake it up a little), and i'd like to make sure i've thought of everything before heading down that road.
out of mkI though mkIV i am the least familiar with mkIIIs. i imagine i will need the motor mounts from a mkIII to put it in, and that the bolt holes for them will already be present on my MF-code block. will mkII mounts work as well?
for exhaust, i know a few people who use a mkIII downpipe in a mkII chassis. similarily, will a mkII downpipe work in a mkIII body with a 1.6L TD motor? will an aftermarket mkII 1.6L TD downpipe like the one offered by passenger performance work in a mkIII body?
will the shift linkage and clutch from the mkIII work fine with an FN-code rabbit transmission or will i need to find a solution to that?
other than sensors, i imagine that the wiring from the mkIII (formerly 1.9L TD) will work with the 1.6L TD, its really just the stop solenoid that is critical. you guys who know my rabbit know i'm happy as long as it runs and gets me there. i'll work on sensors and hooking everything else up later.
i haven't researched the specifics much as you can see but i will be doing that this afternoon. any help you guys can offer is much appreciated!

I had a bone stock 1.6L TD with Giles pump and a stuck turbo wastegate that didn't allow any boost until after 3,200 RPM.. boost maxxed out at 7 PSI or so with the LDA deactivated. It performed fine with virtually zero smoke for streets & highways, so MKIII weight is not a concern.

I use MKIII mounts and they bolt on the MF block.

I had a MKII turbo downpipe mated to the existing MKIII exhaust system. A custom exhaust system (2.5" downpipe to 3.0") was later transferred from my MKII Jetta to my MKIII Golf and it was a direct fit. The underbody of both cars are identical.
will the shift linkage and clutch from the mkIII work fine with an FN-code rabbit transmission or will i need to find a solution to that?
That I do not know, but I used my MKIII 1.8L 8v transmission (gas) and I love the short gear ratios. The 5th gear was swapped out for a taller one, making highway cruising nice. I suppose the MKIII 1.9TD you're looking at doesn't have a transmission?

It's really a simple job, especially if the MKIII had a 1.9L TD. My MKIII had a 1.8L 8v gasser and wiring the 1.6TD was still simple. The "hardest" part was wiring the stop solenoid to the ignition.

thanks malone. i knew when i saw your name it was going to be an informative post on this topic. :)
the one i am looking at is just what i was hoping for. however it has no motor/trans/exhaust :oops:
i think i still have the original mkII exhaust system on the jetta i pulled this 1.6L TD from. if it isn't squished into the ground under the weight off the jetta i'll try to salvage it.
re: transmission. i have a rabbit GTI gearbox and whatever 02A would have come in a 2L 16v passat. thinking about using one of those with a longer 5th. but for now i just want to dump the rabbit's motor/trans in there as a unit.
thanks for all the info!!

Use a3 or a2 mounts for engine and tranny.
a1 tranny and shift linkage is not compatible with a2/a3 chasis.
My mk2 DP will fit your mk3 just fine.
-
I don't believe that you can use the rabbit tranny in the a3 or a2 for that matter because the shift linkage bracket that mounts to the diff housing does not have the necessary holes in the housing for the bolts to go through- this also supports the tranny mount if i remember correctly.
As far as the swap goes I have an 87 mf motor in my 94 jetta 2.0l gasser. Easy swap I reused my gasser clutch and tranny. the only problem I had was that the oil pressure light wont go out regardless of which pressure switches I tried. Hope this helps.

935 you beat me to the punch

will the A2 transmission work in the A3 body? i have the original box from the 1990 jetta that i got the TD engine from, just rememebered :P
-
Yes the a2 tranny will work, a2/a3 chasis are fairly identical.
-
What about the speed sensor,With the a3 being elec pickup and the a2 being cable driven?
Does anyone know if the a3 speed sensor will work in the a2 trans,If not then You'll have to put up with no speedo :(
-
i have a few mkII TD gauge clusters, i could always jam one of those in there until i sort out an electric sensor. thanks for all the info.
-
The Mk3 sensor will fit a mk2 trans. If you need a set of Mk3 diesel engine mounts I might be able to help you out.
-
thanks for all the advice everyone.
i'm going to try to pull all the pieces together to do this nice and clean. so far i think i will be able to get everything i need, but there is still some question as to which axles are required. i need to get my hands on the mkII transmission i plan to use and see what size the axle flanges need to be. box from a 1990 jetta TD.
test drove the '94 jetta that the 1.6TD will likely be going into (with its current 1.9L TD engine that will be removed), i'm happy with it... only disappointment is that the 9.4" brakes in the mkIII bring it to a sluggish stop especially compared to the rabbit i'm used to. i will likely go to 11" VR6 5-bolt stuff later on since i have those parts sitting around collecting dust. not too excited about the increased rolling weight or more expensive tires with 15" wheels but stopping is more important.

not too sure if the power steering pump in the mkIII is the same as would be in a mkII. will either mkII or mkIII power steering pump brackets work to mount a mkIII power steering pump to the 1.6L TD MF engine? should the accesory belt be the standard mkII TD belt for a car with P/S but no A/C?
-
I have the MKIII here,and a MK 1.6L engine with the PS setup on it.I will verify today if it will all bolt up.If it will,you can use what I have to get you mobile for now.

Pump is different.The snout is longer on the MKIII pump to clear the larger harmonic balancer and serpentine setup.
I have the MKII stuff you can use,but it look as if the high pressure line is different.The MKII uses a flare nut connection and the MKIII uses a banjo bolt.May be able to rig something up,or you may have to use a MKII PS line on the MKIII,as long as it will bolt up to the MKIII rack.They used two different PS racks in these cars,but I don't know if there is a difference in the high pressure input line fittings or not.
The best way is to probably swap in a manual rack,as the PS systems are trouble on VW's anyways.I can probably get you a bolt in manual rack (new rebuilt) for under $200.Just making sure it's a bolt in setup without changing tie rods or anything.
Then you can keep the belt setup simple,and just run an alternator.
-
thanks for all the info.
i would like to try using the mkII pump and mkII high pressure line.... as long as they will bolt to the mkIII rack. i guess i will need to determine if the fittings are the same for the input. you wouldn't be able to tell without pulling the line off the mkIII rack, correct?
if this car was just for me i would go to a manual rack in a heartbeat... however i'd like to keep the P/S in this one since it will hopefully be driven by my girlfriend quite frequently and i know the heavier steering is something that would deter her... want to make it as easy and comfortable for her to drive as i can within reason. no automatic transmissions :lol:
-
The rack end fitting should be the same,as the racks are the same between a MKII and an MKIII.
You would probably have to go new on that line,as they always rust and break when you take them off.
The PS line is around $100 new.
-
I'm not sure what year parts you are messing with but if your mkII power steering lines won't bolt up to the rack, you might want to check lines from the later mkIIs .
I think they have the same rack as the mkIIIs.
I swapped the rack in my '91, went to manual and somewhere around '90 they changed ... I think these later power steering racks will swap into an mkIII.
-
thanks for the tip fatmobile. on hold with parts right now i'll ask for '92.
-
i'll use the mkII PS pump/bracket/line, feeding into a mkIII rack (which is the same as a later mkII rack anyway). makes sense. hope it fits up when it comes down to it.

back to the top for scully.

thanks for all the advice on this. hopefully this thread will be a good resource in the future for anyone browsing this forum. good luck with your dad's car scully.
my plan has changed:

my plan has changed:
Woohoo, there's a familiar sight. Last one of those I saw was tucked in the back of my '02 Jetta TDI (bloatware and parts b&tch, can you as for anymore?)
Good luck with that project Lanny. I trust it's going to end up in the GTD? :)

hey drew, nice to hear from you!
haha nice work cramming it into a jetta trunk. i was glad i had my rabbit hatch when we were loading it up :lol:
the 1.9 will end up in the '94 jetta i bought last week as a daily driver. it is a GL, turbo diesel... but sans motor/trans/exhaust... so now it will get its proper 1.9TD (the motor is actually from another '94 jetta GL TD, by chance :P )
i have other plans for the rabbit, none of which are in stone... so for now my focus is on the bus and the '94 jetta. the rabbit won't be my daily anymore!!

ahhh one more question.
a transmission from a 1990 Jetta TD will be going into the 1994 Jetta TD. to make the speedo work, i will need the mkIII electric speed sensor.... but there are two types, red gear and white gear. any idea which one i need?

Red gear is for 3.67 final drive, white (or "natural") gear is for 3.94.
If the gearbox is stock from a '90 TD it will have a 3.94 final drive, but your best bet is to reference the gearbox code to be sure.

hoping to get out to the shop this week and check the gearbox to be sure.
you know your stuff drew, thanks. 8)
