Heya All, Today I finally got a chance to dyno my 1.9 TD cabby! In its stock form the aaz motor make 75 hp and 90lb/tq, this is what my cabby put down
The pulls were done in 4th gear and my boost would peak at 21psi@ 3200rpm and then taper to 15psi after that :rolleyes: not bad for a tired garret t3. The engine definitely has more potential in my opinion and would produce much more with a healthier , smaller turbo.
Judging By how I totally fumigated the shop, the fueling is definitely there now i just got to get a good turbo in!
I out torqued a stock vr6 it made 150 hp and 146tq
A special thanks to Giles for building me the best pump in the world!, and To Brison thanks for the constant motivation! -

Thats Sweet!
Which turbo do you have in mind? K14? -

dont go T2, there are many in Europe that have successfully ran a k24 on the AAZ.
you just have a lazy turbo.....and your IC piping is a big diameter so that will affect the laggyness
I think you should show everybody how its done and get a gt28rs or a vnt22
it would be a shame to have such a nice set-up and run alittle wimpy T2 -

I think a T2 or a K14 pushing 20psi would be ideal.

I was initially content with the base line dyno #'s, but now Im just craving move. :evil: A very good friend of mine has generously offered to let me try his k24/k26 hybrid with only 500 kms use. So upward and onwards I have to space the exhaust manifold off the head for the turbo housing to clear. Need to get some 1/4x3"x12" precision machined flat stock to make some exhaust manifold spacers. Not even 1000kms on the motor and I'm all ready swaping the turbo :lol:

i dont think a k14 or t2 will will be efficient at 20+psi

So I bought some M8 1.25 threaded rod in Stainless Steel from fastenall for $14 and cut it up in 2.5" sections .5" longer than the stock exhaust studs. I had my little brother "The Machinist" make me four 1/4" exhaust manifold spacers and the turned out really well. Now i have everything ready to make that monster k24/26 housing clear my intake manifold.
and finally some pics our future 24 hours of lemons car??:twisted:

So I finally got my turbo upgrade from Bryson and it is beautiful.
A little history on this turbo, It was born a k24 and was bored out to fit a k26 impellers and shaft, within a k24 housing. Hence a hybrid turbo. This was all done at a professional turbo re builder before I owned it. Without further delay some pics.
the swap begins !! the car with the old t3 in
3" SS downpipe removed
next I removed the 4 12point 12mm bolts that hold the turbo on
and the old t3 on the floor 
now to remove the exhaust manifold
and now remove exhaust studs cause there gonna be to short now
and now the new longer SS studs installed
next i installed the double gasket and the manifold spacers
now to prep the turbo , Im putting a plug where the wastegate takes its pressure from the turbo, and going right to the intake manifold for wastegate reference.
then i mounted the oil return line and installed the manifold and turbo
The new turbo spools quicker than the old t3 and will sustain 25 psi of boost.
the car is alot more powerful now and i cant wait till may 30th when i will hit the dyno again and see what kind of numbers this setup will put down. -

And then, we start feeding some REAL boost to it! :twisted:

I'm interested to see how fast it will spool up. My Garrett T3 is great, but I'd like the higher boost to come in at lower RPMs.

Interesting stuff.
I'm looking forward to the new dyno numbers!
That's a nice turbo BTW! I always thought the KKKs work better than the Garretts, for some reason. -

Can't wait to see what it's running now on the dyno. -

SO I needed a new plate sticker for the cabby, and that meant another "Joke" ontario emissions test. I decided to bring it to the vw dealer in orangeville since it a flat rate anywhere $36. I book an appointment with the service dept and let them know its a diesel. (Diesel emissions test in ontario is a VISUAL inspection so long as the exhaust is intact and there is no visible smoke @ idle, it's a pass) I arrive to the dealer with the cabby and the guy at the service desk ask me for Make and model of vehicle. I tell him it's a 1990 vw cabriolet 1.9td. He says "Impossible". He walks out to the lot and looks under the hood then says "OH we'll have to test this under hotrod/ swap class " . Ok whatever I tell him my ownership say Power/D so it is registered as a diesel at the ministry of transportation. FINALLY he agrees to send a mechanic to preform the diesel emissions test. The VW mechanic (nice guy) started my car in the lot and popped the hood, poked around, looked at the tailpipe @ idle, then turned to me and said "you pass". COOOl So then he asks "off the record, how much fuel is this Injector pump really pushing" and I said "It's a Giles pump". "AHHH enough said".
Now all is great I have a valid emisions and valid stickers and I'm all set to lay down some new #'s this Saturday at the Diesel Doctor Dyno day. ONLY 2 more days
