After enjoying life as a Subaru owner, I decided I needed a more economical ride... and found this:
1981 Rabbit L 1.6D 5-sp w/ <50k kms on rebuilt head, solid floors and shock towers
To-do:
- new WP gaskets (urgent), t-stat, hoses (as a precaution)
- shifter linkage bushings
- left/right engine mounts
- quick suspension/brake inspection
Goals:
- full repaint
- turbo (using many of my AAZ parts sitting in some boxes in the garage and some IC work)
- interior removal and update (replaced with sportier seats, cabby center console with gauges, etc.)
- damper/spring/suspension reinforcement

Oh yeah, OH YEAH, you are going to love that 2 door. Yank the back seat and put down a 3/4 inch thick piece of plywood with a cutout for the spare. Carpet goes all the way up to the foot wells and you have a very nice mini SUV. I haul all sorts of stuff with mine but I did need to raise the springs in the rear after I loaded it up with 11 gallons of Veg Oil. Why burn the expensive stuff?
Only one question. Did they charge you extra for all the green slime on it? Crazy how folks don't clean a vehicle before selling it. I knock the price offer when they do that.
And now that you own one of these critters all free time will now be spent on it. Trust me.
Mine got a cruise control install start on it today.

Nice! What color interior is that? Lipstick red? Royal red?
-
Looks like the VW tan to me.
-
Very red. ;D

Nicely weathered. Let the Mods begin. Seats first. Gotta be comfortable every mile. Ricaro rules.
-
Let me know if you wanna get rid of that 5-speed ;D

Engine and trans are out... trust me, you don't want it. Diff bearings have taken a vacation, destroying the output seals... this explains why the engine smells like gear oil. This just gives me the opportunity to revise my plans. As I still have my 020 from the AAZ with a <10k km clutch/flywheel, an upgrade is in the works. :P Now I just have to figure out if the current axles will accept 100mm inner CVs or if I should swap over the 90mm flanges. I do want to split the trans from the AAZ in order to install a new main gasket to not have any issues with tech inspections at auto-x events.

Looks like the vacuum pump has been upgraded.
-
I believe it has... looks identical the one from my AAZ kicking around. Did a quick test fit of the turbo and manifolds after degunking the the backside of the block with some diesel and elbow grease. Working overtime at work tomorrow, so progress will come on Sunday when I pick up a 1.6TD intake manifold in order to match the port shapes.

A lack of updates usually means I'm busy... and having a cool boss that gives me free reign of the shop during lunch breaks gives me reason to be busy, especially when the sandblast cabinet is part of the deal. As a result many items have been sandblasted and repainted with the exception of the chassis itself.
- engine bay painted in racecar (generic rattle can) white
- steering rack repacked and installed
- new tierods installed
- pedals sandblasted, repainted, reassembled and installed
- purchased used (low mileage) set of Bilsteins and lowering springs (to be cleaned up)
- rear axle completely rebuilt
- poly bushings installed
- new front control arms (w/poly)
- drilled, tapped manifold to install EGT probe
- intake/exhaust manifolds finalized/installed
- new engine mounts (brackets blasted and painted)
- installed new brake booster
- purchased used Corbeau FX1 seat
to do:
- new rear main engine seal/gasket
- trans main seal
- convert mk3 AAZ trans to 90mm flanges
- install clutch and assemble engine/trans (+timing belt at this point)
- finalize turbo oil feed and return lines (weld appropriate fittings for oil pan)
- install rear axle & suspension
- install front suspension
- install MC and new brake lines AtoZ, bleed brakes
- design and manufacture lower front susp brace and driver's seat brackets
install engine
- install wiring loom
- interior... everything
- fabricate custom exhaust
My goal is to have it done by Aug 23-24 with a couple of weeks of shakedown before my first autocross Sept 7.
Pics to come tmw.

Its August 30th is it done yet?
-
I wish I had the ability to strip it down fully.. :( I am considering picking up a cheap HONDA in the mean time so I still have a daily! haha
-
No bad 8v thats what the people at tdi club said I should consider and it was horrible. That is unless its an 80s honda wagon with awd. Those are cool.
-
I'm happy to see people take an interest in it... long story short, no it's not done, but I'm pushing like mad so that I can get it done before the craziness starts in terms of schoolwork (final-ish year in Mech Eng).
And here's the long story:
Probably the worst month of motoring, EVER. On my way to work Aug 12 (keeping in mind that I just drove home from the cottage the night before) my Subaru decided to lunch on its timing belt. Pretty much the worst case scenario applies here... accelerating in the left lane of a 4-lane highway, but I managed to coast it off the highway. Engine is toast and the car has to be parted out before the snow flies. After missing out on 3 or 4 decent diesels I decided to bite the bullet and bought a 95 BMW 525i w/5sp... got it for a steal, took care of the maintenance/small problems and was driving like a dream until the notorious BMW cooling system reared its head and sheared the upper rad hose from the end tank of the radiator. Fingers are crossed regarding additional damage in the form of a head gasket or warped components. So I now own 3 cars, none of which run but parts are coming in tomorrow for the Bimmer and should have it back on the road by Thursday.
As for the Rabbit:
- Solved the drive flange problem, in theory. Ordered a set of Scirocco axles with 100mm flanges.
- Suspension & brakes are done... just needs an alignment.
- Engine is in, but still working on some cooling lines and oil lines
- Currently fabricating the exhaust (2.25in downpipe, high flow cat into 2.25 exit with turndown... still not sure if I'm going to put a muffler)
- Currently working out the wiring to have a hatch mounted battery for better weight distribution.
A couple of other small bits remain but listing those would be tedious...
Took some measurements to make a rough exhaust design:

Waking up from hibernation... time to work on the Bunny. Last Fall I decided to focus on my studies, so the Rabbit fell by the wayside. :P I did a few odd jobs to get the driveline bolted up so that it can sit on its own wheels for the winter but not much more. Pulled the tarp off the car last week to pull off the Snowflakes in order to start refinishing them only to have 6 inches of snow dumped on it 2 days later.
Regardless, by having to drive the BMW all winter the budget tightened up quite a bit - $100 of gas every 1-2 weeks does that. This forced me to re-think the Rabbit project a bit. The main focus now is to have a good commuter car, so I've dropped the turbo and custom exhaust and install all the original bits. The Scirocco axles were also a waste of money as the outer CVs did not work, so I ended up converting my 020 from the AAZ to a 90mm flange to use the axles that came with the car.
Task list to get it running:
- coolant/heater hoses
- replace some trans mount bolts
- install alternator
- install engine wiring harness
- finalize battery wiring (trunk mounted)
- paint wheels, new tires
- fix MC reservoir leak (either grommet or reservoir)
- front corner lights
-
Do you still have the measurements for that exhaust set up? Would you mind sharing? I'd like to order some pipe soon ;)
I'm a big fan of being realistic with projects and enjoying my cars instead of just seeking ultimate performance. Lots of things get sacrificed for a few minutes at the track instead of having something all around useful / comfortable / practical. That being said are you sure the turbo plans should be dropped completely? Coming from another guy who dailies an na rabbit I certainly feel like a bit of boost would make the rabbit more practical all around. Efficiency and practicality. My .02! But glad to see this build resumed either way!

As far as an immediate running car, yes, the turbo has been dropped. If I need to travel longer distances, the 'ol 525i is more than capable for the time being until it goes under the knife for some body work and more.
I will continue working on side projects for the eventuality of a turbo install, but I might develop a full drop-in, refreshed engine package. Since I have a lot of AAZ bits floating around, I won't rule out a full AAZ swap if a long block pops up locally.
I'll try to dig up the CAD file... from what I remember, the DP-back system was done using less than 8-ft of straight tube and 2x 180deg J-bends that cut at the appropriate angles jigged up on a bandsaw. I never managed to mock it up so I can give you rough dimensions and angles for a 2.25in diameter setup, but cannot guarantee a perfect fit. For the DP I had planned, an additional 2 J-bends were purchased but never cut.

I have a jig for a mki downpipe I made. It sucks to make as it takes about a weekend to get it all good. I am making them 2.5" and usually around 250.00 plus shipping as I am in no hurry to make any. Plain ol' carbon steel.
-
I may have to keep you on my list theman if I can't figure out a decent Downpipe myself. Can you do one for a vnt15? Or would that require significant changes. I know it sits lower right?
Thanks for the info ak. Sounds like you have a solid plan. I'm looking to go turbo sooner rather than later though because I'd driving a lot around town lately and i could really use the extra pep!

No sooner have I said that I'm considering an AAZ, I find a short block locally. Oops. ::) ;D

My jig is for the stock KKK and Garrett turbos, so it will not work for a VNT. That said since the VNT is low mounted it will be easy to do on the car. It should be a U bend cut into two 90s and welded together, one down and one back. I have a jig made for the rear engine mount for MKII and MKIII to use with the VNT...I like making those.

That sounds painfully simple. And that clears all the shift linkages and what not if I just go straight down and straight back? I saw some question mark looking pipes around before...
Sounds like 100$ of exhaust pipe and a few hours I could have a full 2.5" system... Woot!

I am now in the process of making/machining all of my timing tools... I just refuse to buy something so simple, especially when I have no income right now (damn winter is killing the ship repair business and my summer job). I will also be building my own pop tester due to my recent discovery in the injection system. It seems like I will be rebuilding my injectors. I pulled them apart today and it was near impossible to separate the nozzle (2 are frozen and the other 2 tough to move). Will try soaking them in diesel tomorrow as I would like to avoid that expense as well.

Things always balance out, right? Got a job at a race shop and the fuel tank started to leak on the 'ol Bimmer... $550-650 for a new tank. Getting the Rabbit back on the road has become a bit more urgent. :-[
-
I'm enjoying your thread a lot. I'm in the same situation. Subaru lover, bought a Rabbit, Subaru starts breaking.
Most likely wasting time while at work.

Well, working on Porsches and some awesome race machinery has tied up a decent amount of my time (in addition to Formula SAE designing after work) but I've been enjoying some of the perks of working in a shop with a super chill boss. I've also been fixing friends' cars after discovering the incompetence of many 'professional' mechanics. Let's just say a female friend got suckered into an alternator job for a hot no-start on her Civic which was unfortunately masked by an extremely cold winter. Hmmmm, maybe the CEL and extremely rich cold starts were clues that were overlooked. I fired up my scanner diagnosed a bad coolant temp sensor even before I got to the codes. Her mech was trying to convince that the alt was overheating again... BS. Sorry, just venting. >:(
Anyways, I've solved the fuel tank problem on the Bimmer by keeping it under a half tank. ;D As for the Rabbit:
- Snowflakes refinished, cheapie tires for commuting mounted.
- MC resv. grommets resealed
- Cooling hoses plumbed and system filled.
- Injectors/nozzles cleaned and reassembled (no, didn't pop test them... only temp install)
On my list this Sunday:
- Temp weld the original batt tray.
- Engine & interior wiring
- T-belt
- Inj pump priming
- trans bolts
- etc.
-
Sorted out my fueling/priming problems and got the thing running after over a year of being dormant. In fact, took it for a 100m drive down the street and it was noisy and glorious...
Only some minor tasks left:
- Hood mounting (broken mounting bolts need to be drilled out)
- Ground new headlight wiring harness
- Mount new power distribution setup in engine bay (hatch mounted battery)
- Install horn
- Tighten pass control arm mounting bracket (stud spins in chassis, will need to weld or come up with something different)
- Align suspension
- Diagnose oil pressure light (by installing my VDO gauge)
Pics to come...

Busy with my final year in engineering (projects, etc.) but finally got the Bunny running well enough for daily driver duties. I still have some issues with the wiring (GPs and dim front indicators) and not too happy with the pulley alignment on the v-belt. The old stock exhaust is leaking, driver's CV joint is torn and I managed to screw up my wheel bearings with what I thought was going to be my axle upgrade (Scirocco CVs) in order to deal with my 100mm drive flanges (AAZ trans).
Regardless, she drives, starts at -12C and even the gas gauge just started moving after 85km.
