Hello and recommendations for a TDI 4runner

[tindias]

I believe that both the 1.9L and 2.0L TDI  motors can be bolted to my existing driveline via "acme adapters" in Canada.

Their plates work with any 22R Toyota transmission.  When I spoke with them, they said it would work with MK3 engines of any kind for sure.  They were unsure about MK4 and newer, but I believe the bolting pattern for the transmissions has not changed.

Look up aaz on ebay and you will find 1.9TD aaz's going for about $2200 shipped from CA. Decent low milage. I paid $2400 for mine with about 30k miles on it with a 5 speed.

As for putting in into your toy. I made the adaptor myself, and have all the prints for everything. I did a full adaptor that wraps all the way around the toy bell. Mine is mated together and going into a rock crawler.

Good info here..........

From what I've read the adaptor will work with a TDI (if I ever wreck my car I'll let you know 100%) I think the angle of the motor vs the trans might be different though.

Thanks.  I can't find anything referencing AAZ on ebay currently - no motors, only pumps forsale.

Can anyone tell me what the AAZ designation is - and years that it applies?

There is a Jetta here (1998) - TDI - $1500.  Owner says the pump is going bad making it hard to start.  The bad news is that it's got 177k on it and I'd be tempted to rebuild it, which is going to run me at least another $1k... '

Here is a link for a motor.

AAZ is a Canadian (and European) motor. In Canada it was used from 92 through 98. In 92 only Passats had them. Actually maybe it's 91.. I'm not positive.

Thanks for the link.. Somehow ebay doesn't like a straight "AAZ" search.
Motors look good, reasonable mileage.
stock 75hp and 115ft/lbs is a bit anemic... Maybe I should ask over on the IDI section, but what's reasonable power output on these things when keeping them reliable?

Is there a good T3 manifold available?

I found a local 98 Jetta with 177k - leaking some oil, pump is failing.  TDI and complete for $1500 (entire vehicle) - I'd be tempted to rebuild it + cost of a M-TDI pump, we're probably looking at $4k.

[mr.woods]

If you can get the whole car why not just keep it straight up TDI?  I would just see what is wrong with the pump, or if it even is the pump. I would have went with a TDI setup if I was able to find a donor car, But they want $5,000 for TDI's with over 200k around here.

[theman53]

yeah if you got the wiring and can get the whole car under 2,000 I would go TDI too...not mTDI full electric since the wiring is there like Mr. Woods said. I bet it isn't the pump.

That is pretty typical power for a TDI stock, the MK4s and newer are 150-200 ft lbs.  For an MK4+ plan to spend more, but you can flash the ecu for increaded power.  The AAZ can make good power with pump tuning, big injectors and other upgrades.  If you are looking for power right out of the box you could pick up an NPR motor=)

You can chip tune ANY eTDI not just the MK4's.

75/115 is stock AAZ power, but easy to see the 120/200 range with pump mods & an intercooler. The stock injectors are fine for any tuning on an AAZ within reason. FIxing the crank nose isn't an option IMHO, check Libbybapa's profile for the fix.

North american TDI's in stock form 1Z/AHU - 89/149 (MK3 golf/jetta/b4 passat),  ALH is 89/155 (mk4 golf/ jetta), AFN 109/173(B5.5 passat)  ... i think that's all correct, there is some overlap here & there with the VW half model year changes.

Keep in mind that torque is available from around 2000rpm, so nice for a small truck.

Without a turbo upgrade I's say +20-30% can be found with just a chip tune on any of them, +40-60% tune and injectors & +100-infinity% with tune/injectors/turbo/clutch/... 

180hp/300+ is pretty easy for ALH guys to see with a turbo/injectors/tune & then its clutch time, the 1Z's had slightly weaker pistons & maybe rods so aren't as popular for high HP builds.

This guy's got a nice 1Z/AHU build page http://www.stealthtdi.com/Jetta.html

Those numbers are off the top of my head, i'm sure others can provide some tuned hp numbers here.
All of the TDI's in e form can run a VNT turbo, the 1z/ahu's need a ecu reflash to newer software for this tho & all benefit from a EGR delete or a upgraded CCV filter system to avoid clogged intake manifolds (something you should check on a used tdi purchase)

The other thing to watch with a used TDI engine is if its out of an auto or manual tranny car, auto's got a 11mm injection pump while the manuals got 10mm. Auto's had smaller injectors though while the manuals had larger injectors. That doesn't matter cause you're going to want some Bosio injectors anyway. Most tunes driven mildly will net better fuel economy too.

Pushing more than a small sedan a nice large intercooler and a upgraded oil cooler are a good idea. Many tuned tdi's run fuel coolers too.

There's a guy promising mtdi pumps from e pumps with a tiny mod, i'm taking that with a grain of salt until its proven.

ebay england always has land rover mTDI pumps, a simple mod to the IP bracket & its installed in a afternoon, I doubt the electronics could be figured in that time. Then you can tune with a screwdriver! Just don't discount the mTDI based off a few posts here, do some research if you're even just a little interested.

thats all i got, time for work...

I don't count the mTDI out, but I have to budget for the only working mTDI pump that seems to have good references - which looks to be around $1300. 

I'm just not interested in integrating the mTDI electronics.  I'm capable of doing that, but simply don't care for the hassle, nor do I care for the expense of the tuning software and defeating the electronic anti-theft ($400?).  It extends the learning curve and project length.

I like the references to the AAZ motor 120hp and 200ft/lbs is right no par with the 22RE gasser (stock).  This would be a power reduction on my turbo motor...  I really need to get to 150hp  200-250 ft/lbs.  I do recognize that those power peaks are pretty early on a diesel - maybe 1500 rpm sooner than the stock gasser and mileage would be significantly improved.

I have a newer T3 that I'm running currently -  a .48/.60 - I'd like to put that on whatever motor I choose to run with.
I'm also already intercooled.

I appreciate the commentary and contributions here - this is a great forum.

For reference to the discussion & comparison:

22RE('85-95):

bore - 92mm
stroke - 89mm
compression ratio - 9.4:1
116hp @ 4800rpm
140tq @ 2800rpm

[dcg9381]

Thanks, I didn't realize they were that anemic stock, although the peak torque is similar to a diesel.
The turbos do a lot better, I have a collection of dynos at:

That t3 is bigger than what came stock on the 1.6ltd.  You could use it but turbo lag would be significant in a heavier vehicle.  The 1998 jetta probably has a garrett t2 or the kkk equivilant which will work much better in your application.   I'm running a k14 on my mtdi right now in my toyota pickup and it's nice.  Spools up fairly quick and I'm making full boost, 18 psi, from 2000-3800 rpm.

It is possible to make more power than your turbo 22re but it will take some upgrades like larger nozzles, a better intake, porting the head,a vnt turbo, and a very well built mtdi pump.  The tdi does feel really torquey though, with good low rpm grunt.

So, personally, the only reason I would ever do another swap like this is if I wanted to.  It doesn't make sense to do this for any other reason.  My final cost was over 5g for the conversion and that doesn't include my time.  Yes I'm getting better fuel economy but I'm only saving about 10 bucks a week so at current fuel prices it's going to take ten years for the payback!

I also notice extra weight in the truck more than before.  I notice a big difference in acceleration and power.  You might find this hard to believe but I fill the fuel tank and I feel the difference.  I hall two passengers and I feel a big difference.
