Title: AAZ vs 1.6td?
Post by: chrisg on October 26, 2010, 12:01:35 pm
looking to do a swap from my 1.6 NA and i stand at a cross roads as to what has more power potential. now i know i'm looking in the wrong spot if i want "real" power with out spending lots of money, but just something that will get me moving better than the 'ol trusty N/A

just kinda looking for opinions, disscussions, questions, just a general pros and cons of each.

either motor i end up getting i'll be upping the boost, and fuel, just easy mods.

so all in all, who thinks which engine is over all a better one?

AAZ has more potential down the road. It's a nice engine in the light m2 chassis. Plus, you can go mtdi by switching the cylinder head, pistons and building a mtdi pump if you want later. And the 02A transmissions are better than the 020's.

You don't have to change your trans. It will still bolt up to the AAZ.

Well in that case it's pretty much a toss up.

AAZ is a dull lazy sloth of a motor

The 1.6 is fun.

Perhaps... but as the saying goes:

"There ain't no replacement for displacement"    ;)

Don't know if you got the 205 GTI or the Golf GTI in both guises?

the smaller motor was always considered to be the drivers option.

Sure the 1.9 can grunt but I dont need that in a small light chassis.

Yuuup ;) a lightly modded 1.6 will be more "fun".

Or as we say in the states:

"Nothing beats cubic, or pubic inches."

This topic also interests me as I have a 1.6td GTD lump but have often wondered about going for a 1.9td AAZ, never really found a comprehensive list of the pros and cons of each lump though.

For me personally the 2 main factors for the engine choice would be fuel consumption and driveability, I especially like power low down never been a fan of revving.

AAZs definitely have more low end torque. Mileage really depends on your right foot. My 93 Passat gets the same or better mileage than my 85 NA Jetta, FWIW.

My aaz with Ported and polished head ( extrude a hone ) goes...

I just got the PD130 back from them and Iam waiting on my custom intercooler from Bellintercooler

I looked at a GTI intercooler yesterday and it was massive 1-1/2 thick, probly 33 x 33

with power your going to need a LSD in your trans, I did a custom CHD, 3.67 with 16V internals
.71 final, peloquin lsd, all bolts in and out ARP 12PT
Ooh yeah it's pretty, powdercoated satin black...

No budget build, company truck...

so here's what i was thinking. i can pick up a 1.6td with no trans or harness for $80 so i think i might do that, do some general maintance. then up the boost, up the fuel (eventually send it over to giles when i get some cash, summer time perhaps) and that last post got me thinking about a small intercooler possibly.

so with a 1.6 td intercooled, running maybe 10-12 psi, with the fuel up. should run pretty quick? now, remember, i say "quick" in comparison to my N/A

You can do 17-ish PSI fairly safely. Especially with an intercooler and an egt gauge.

yeah it'd be quick and fun, i'd run more boost tho since u'd have the intercooler, ur not going to win a bunch of races or anything, but it will be a very fun to drive car

The fuel consumption issue is negligible

Driveability depends on what you want....I've had two 1.6s and two AAZs, I'm now building my next motor and had both motors available - 1.6 block and 1.9 head.

fuel consumption is not really a big issue. i mean with my car i have clocked 850km to a tank, but that was babying the crap out of it. and the smiles and fun of flooring with a cloud behind you is just worth the extra penny at the pump.

and running 17 psi, how reliable would this be? this is a daily, but that being said i'm not looking for bone stock toyota corolla reliability. just something that will start in the morning.

I run 17 psi on a k24 with no intercooler with no issues. Of course I have to keep an eye on egts as they climb very fast. I also have arp bolts and a metal headgasket but those things aren't really mandatory.

I ran 30psi on my 1.6 and that suka is still on the road.

But..

I set it up correctly, MLS head gasket, ARP head studs etc etc.

But oh what fun..

What turbo were you running 30psi with?

i don't know that we ever got any peugots here...  i don't think they'd do well, after fiat and stuff i think small european cars left a bad taste in usa's mouth, kind of like diesels other than vw's.  not that i think fiats are bad cars, they were just sold here at the wrong time and by people who didn't know how to service them so they got a bad rep
