Andrew has said on many occasions an AAZ will produce the same power as the TDI's with the same modifications. Just consume 15% more fuel doing so, because of efficiency.

So a compound k03 and k24 setup with all the room in the jeep/4runner... and some mad pump modifications (like 11mm head and big huge dirty injectors) were cookin BACON>

What about a VNT 2256 and a 12mm pump....that is what I have. I also have the hybrid that we just made of the T3 vw hot side and the T3 mercedes cold side and that same 12mm pump. I plan on making an MTDI out of my AAZ with it, as I think I wrote early on in this thread. Also, I have 80% of the parts and even if I don't make the OM617 power, I bet I will be darn close and 1/2 the weight.
Even at an AAZ I think I could push 200HP and hopefully closer to the high 200's *wishful 280ft/lbs* if the turbo and 12mm pump will suffice.

If your only looking for 200hp an 11mm would do that with no problem. A 10mm will do 150hp. There wont be many advantages to the 12mm head unfortunately, disadvantages really being that you will be limited to like 3700-4000 rpms. HOWEVER! If that massive turbo will spool like a mother before 4000 (like 2500) then you have a good candidate for some mad power.

I feel that the 300ft.lbs would be achievable at that point. It may require some knowledgeable pump tweaking, to do with advance curves though.

I had the 12mm pump on my 1.6 for a few days. It was leaking out the screws up top, so I had air. But with its current Gov spring setup it would go 72mph in 3rd gear, probably more but it sounded too violent for me and I would shift. With my AGS and 3.67 R&P that is approx 4,800.
For the most part when done it "should" be the wife's unit, so I am not too bent out of shape if it doesn't rev to the moon for her.

Well if it sounded bad at 4800.. LOL thats like taking the 9mm pumps to 5800.

Its just that the plunger is physically bigger, and is harder to get the mass moving back an forth as fast eh?

FWIW it ran about as good as my Giles pump. It had more bottom end snap, but after that it kind of pulled like the Giles rig. It definately had more get and go than a stock VW pump.
BTW GILES pump would make that noise around the 79 mph mark in 3rd. If I was driving spirited I would usually still shift at 70mph.

190? That is a disgustingly low number for a 6 cylinder. ;).

You could easily out do that with a slightly modded TDI or slightly more modded AAZ.

usually a gasser makes 1:1 power:torque ratio..

i thought 190 ft lbs was GOOD for a 180 cubic inch engine that spins 8000 revs..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

I think with me that fine line between want and need is somewhere around 5,000 RPM  : D

i bet with a proper turbo a 10mm can do more than 150hp, lets not forget daves 1.6 that did 195whp with a 9mm pump.  or joshs car even, he did well over 200hp with a 10mm pump on his 1.6.  i guess the difference is much larger turbos than people usually use on a tdi and also perhaps revving higher since ve pumps can only move so much fuel per stroke so the higher u rev the more fuel u can move, tho u still can move put so much in per combustion.  but also just to be contradictory, i have heard(note that means this is hearsay) that 12mm pumps can be revved higher but you need to have high flowing injectors, which makes sense to me, but i'm not about to go try and break a 12mm pump haha.

yesterday i was driving home from getting supper with my lovely lady when i got behind a jeep the bumper said "Yes it's supposed to smell like that" and the license was "DSL-JEEP".  when the light turned green it was obvious he was running bio or wvo haha.  so the next light i blew a bunch of black smoke while we were sitting there, and at the next light i was able to get next to him(york, pa has alot of redundant traffic lights) i said hey is that a 617 and he says yep (light turns green pull to the next one) and i asked "hey do they make an adapter for that or did u have to do it your self?", he said "i made it, and i sell them mercedesdiesel4x4.com"  cool right? haha  anyways that light turned green, and the turbo on it sounded great.  those mercedes have a lot of power potential, but i don't think they had much power stock haha.

I passed on a 400.00 jeep...it was a cherokee and I need the wrangler for the woman. Cool site and I looked they do much more bellhousings than for a jeep, but sadly all are for the MB engine.

yeah good prices too i thought especially for the little father son business that it appears to be.  i can't imagine that they are moving thousands of these things.  maybe they'd make a vw adaptor.

Well, if all goes well I pick up a 2002 Jeep Wrangler Monday. All he has to do is clean it out and take my money. It has a blown engine, 4 cylinder with a manual trans. It is in excellent shape and I got it for a ton less than blue book...I would almost say for my looks and a song, but it took some $$$ too. I only saw 2 small, very small rust issues and it looks very, very good for a 2002 Ohio Heep. I will build a TDI out of an AAZ block and drop it in next year. 12mm cummins pump and a 2256vk probably if not that then the VNT 15 I have.

I will post pics as soon as it happens.

i would honestly consider the VNT15 as the best option.. instaboost!

Every turbo you've ever had on your rig has had "Instaboost"... ;) No matter what the size of it, the condition or the engine its on this is Kevin's reaction to it;

"Yeah that Holset HX-50 over there on my 1.6? HOLY *** DOES IT SPOOL FAST"

"I have a K03 on my 1.5, it doesn't spool anywhere near as fast as my HX-50 did... BUT DAMN ITS PRETTY FAST SPOOLING!"

LMFAO.  :-*

It all depends on what transmission you are using and what gears its got in it as to what turbo you choose.
