Alright so I'm building an AAZ that needs to be reliable but I also want to be able to run the 1/4 in 13's. Here is what I've got planned so far.
complete AAZ overhaul,
K26/24 Hybrid
Giles Pump
Borred out to .5mm Over
Stage 3 Clutch
Intercooler
2.5" turbo back exhaust
I'm looking for 200 ish HP, and much more torque, I want over 300ftlbs of Torque. I do plan on looking at a Nitrous System, maybe a 50 or 75 Shot to be injected at WOT. Only for 1/4 mile racing
What else am I over looking at this?
-
You may want to get some upgraded rods and possibly a crank girdle. Definitely an aggressive exhaust porting. I would go 3" exhaust rather than 2.5".
-
I do have one extra girdle already made up if you decide you need one.
-
crank girdle? sorry i don;t want to sound like a moron
-
well, a main bearing girdle, yes.
it needs to have the holes drilled, but there are dimples in the centers of where they should go, so you dont have to worry about drilling in the wrong place.
and it needs the slag cleaned off it(really simple with a wire wheel/grinder)
and you will need to come up with spacers to go between the girdle and the main bearing caps, but that should be easy/cheap for your local machine shop to do.
all the expensive/hard work is done.
you could have it for $70 plus shipping(a real steal compared to the $400 they cost commercially)
the $70 covers what I paid the machine shop to make it, plus ten ish dollars for my trouble(the machine shop needed constant hounding for over a month to get them to spit these out)
just let me know if you are interested!

So its for strenghing up the Bottom end of the motor? I may be interested in it, I will def keep it in mind.
Any ideas what kind of connecting rods i'm going to need? I heard rumours that VW's have forged internals? I know the ABA had forged Rods and Pistons
-
I never did any of the rods or the girdle on my AAZ, but then 300 HP was not a goal. I used late rods and ARP studs/bolts throughout. Better rods are the later Pumpe Duse rods from a TDI. Do the head porting for sure. It made mine breathe a lot better. Also a PD 140 or PD 150 intake manifold flows a lot better. Get an air/oil oil cooler in place of the water/oil one. 3" is overkill for these engines on the exhaust.
-
Well I'm Aiming for around 150 to 200HP, and over 300ftlbs of torque before Spray.... ;D .... The Motor I'm rebuilding is a 97 AAZ. So TDI Rods will fit in the AAZ? and For the intake I'm planing on making a custom Intake, and Exhaust Collector to the turbo,

Sounds like a bear. Yes, the PD rods will fit the AAZ.

Where would I be able to pick up a set of those?

Have you read this about the K24/26?

I think the dealer would be the only source, but you could try a want ad in the classified section.

No I hadn't read that, but now I did. What would you suggest for a turbo?

Actually, be careful. I don't think PD rods will fit. They have bigger "big ends". The 1Z, AHU, and ALH rods may be fine though.
-
I believe myke_w has H-beam chromoly rods for sale that will fit the AAZ. Used to have them for $550 shipped which is a very good price. kermatdi also has H-beam rods for the AAZ for around $700, I think.

I will def look into it, I don't feel like blowing a rod going down the road or strip
I was recommended Not to run NOS on it because I already have a force induction motor and anymore I risk blowing the block...Any Input on that?
-
I got the temporary motor for my car so I can rebuild the one thats in it. The reason I'm not rebuilding the new one is its only got 170,000KM on it and the one in the golf's got 353,000KM and is pretty tired lol
And I know the car is in rought shape, someone did that to it at night when buddy was sleeping lol

Got the parts car running today took it for a rip up the street....Damn that thing can pull :D, made me happy to know how good the motor worked...then drove it in the shop and ripped the motor out of it lol, we are getting too good at this because I brought the car into the shop at 10AM and at 1:30PM the motor was sitting on the floor and I was prepping the transmission for removal lol.

no one on here likes the K24/26 there isnt enough exhaust getting out of it to be a performance gain. the K26 will out perform a 24/26 hybrid any day. a K26 makes 35 psi happily. thats what i was told to use.

I think now I'm either going to run with either a K24 or K26.
After helping my friend bring his smashed car home to NS I stayed for a couple days...Meet a Few people from Custom Obessisons. One of the guys gave me a full size TDI Factory Intercooler ;D How hard is that going to be to mount up on my MK3?

I dunno, you better send it to me for a test fit

HAHAHHAHA Your funny, I carried that thing on the train with me and put it in the seat next to me lol. I couldn't figure out why people where looking at me funny at the train station ::)

When you figure it out let me know!! I'd always figured that would be the easiest way to intercool Jezebel...

Finished Up the welding on the floor of the car today, still need some filler and undercoating. Before welding up the holes I decided to take a picture of the Floor :D

I love MK3's but in Canada I think its Impossible to find one with no rust like that. Thats not to worst I've seen, The Parts Jetta I picked up I stepped in and onto the floor in the garage ::)
I plan on completly redoing the whole floors again lol
-
Ya just gotta come out here to the wet coast, eh? Pretty rare to see rust-outs in my neck of the woods. Pretty much every car in the scrapper is there due to a crash.
-
:D AINT THAT THE TROOOOFFFFFFFF!
-
I'd Love to find an Golf Shell in good shape to rebuild, But since I'm on the Salty Coast :P I don't think I'll find one, So I got to learn to get handy with a Mig lol
-
im on the west coast, and it rains and rains, and rains here. but we never see rust like that. they rust out on top before the bottom rusts out. but we get no salt on our roads. and like Bryan said, we get to see all the cars in the wreckin yards piled up from a drunk or something.
-
So I went up to the shop the other morning.... And this is what I saw.... :'(
My Poor Little Golf,

well Cat, there is more coming. So you better stock up on some beer for the big storm, I'm sure your honey will need some more booze too. :P
-
Picked up some Baylees on the way home ;D
-
So I started preping the Golf to swap motors so I have a better running one ti'll i get the new one built up...I'm getting too good at taking MK3s apart...you remove 12 bolts and 6 screws 4 clips and 2 wires and you end with this ;D ;D:

Takin the old AAZ out tomorrow and putting a low mileage one in.

Any progress on this build?

i remember posting a thread about a guy who put ford escort 1.8 pistons in an aaz for a bigger bore, it was like a 2.2 or 2.1 liter aaz

Not Much, I'm still in the middle of swapping motor so I have a reliable one in the car while i'm building up one. November is coming to an end so my car is off the road ti'll April (seasonal car). I haven't been working much on the car lately. I will get the motor in and car running by the end of this week...Just so I can move it from the garage to the storage thingy lol.
