1.9aaz moded to TDI in a Jeep.

[theman53]

In what I think is if I have a 1.9 I will definately spool the 2256 just fine. I don't know yet as I haven't done it, but from what I gather on libbydiesel's setup it will be all in how the vanes are adjusted. Right now it has a 4 cylinder engine and manual trans, so I don't know if I am going to go with the bigger trans or just see if this one will like it. It will come down to the cost of another trans and if the adapter plate will work with both or not. If it will not I may try real hard to find the bigger trans for it.

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.

my VNT20 is NOT instaboost!

nowheres close to it.

neither was my K24..

but the VNT15, even with the vanes open, was instaboost..

how can you claim that a VNT15 is NOT instaboost?

the second you throw any amount of heat to a VNT15, it spools..

an HX50.. that may never spool on a 1.6D.. we would have to figure out how to turn 10k rpms to spool something that HUGE..

if ive claimed any of my other turbos are instaboost, im comparing them to a similarly sized turbo.. my VNT20 spools MUCH QUICKER than a T3 or K24 does.. the VNT20 is a variable nozzle turbo, of course it spools quickly..

after it exploded, i kinda hatd it, and thought they were junk, but honestly, out of all the turbos ive run on my car, the VNT15 is my favorite, hands down! it spooled quick, and pulled hard right until the rollers started skipping..

Well here it is. It will start the slow process now. 2002 jeep wrangler 2.5 4 cylinder manual trans shale green metallic.




It has new tires on the front, pass front fender is rusty and there is a small rust spot under the driver door. It made it on its own power to the house but has a BAD engine knock *guessing piston skirt broke off* but it misses and sounds like it is going to explode at any second. Everything works that I played with except the Odometer, but I think that is part of that "jeep thing" they brag about, which means all Chrystler products electrical systems and all things associated with them are junk. Brakes feel new. Overall, I am pleased with this purchase...and the wife is too. Amazing considering it is another non running vehicle. I could make serious money on it if I dropped in another jeep gas engine and sold it, but I believe this diesel will be most fun.

[theman53]

Next question is the 4 cyl and 6 cyl have different manual trans. I have to make all the adapter stuff either way. Should I roll the dice to see if the 4 banger trans is up to the task or just get the nv 3550 right now. Also, I have no idea if the transfer is the same between the 2 trans, I think it is, but these jeep sites are nothing compared to our GTD. As long as it is taking my machinist on the 1.6 TD head, I may take him my TDI head soon so it will be ready next year.

So I don't lose it and maybe someone else can use at a later date. Looks like the NV3550 can be used in all jeep 4.0 from 1997-2006

http://www.jeep4x4center.com/knowledge-base/jeep-wrangler-fluid-capacities.htm
Also looks like all heeps had NV 231 transfer case except Rubicons. So I can mix and match trans.

http://www.novak-adapt.com/knowledge/ax5.htm
That site tells me the ax 5 has only 21 spline transfer, the bigger trans had the 23...I don't want to spend too much on finding another trans and T case combo.
EDIT: I wish I had JB's money, but that is about it

get an AX15/R150

in the Jeep, they were called AX15..

in the toyota V6 trucks, they were called R150..

they are just an aisin-warner trans..

very tough tho.. ive seen lots of 350 chevys mated to R150 toyota trannies, and live lots of miles as well..

im not very impressed with the NV3500/3550 trannies.. they have weak syncros, and 5th gear often times goes out..

the Aisin-warner trannies are BULLET PROOF from my experiences.. ive personally wheeled the hell out of one for like 50k miles..

[theman53]

Cool, the ax 15 are cheaper. The syncros in all my GM stuff always go out on 2nd, but they are tough as hell. Since this is for the woman mainly I would rather go with a smoother feeling trans. The ax 15 I didn't think had as good of gear ratios as the NV but it really wasn't that big of a difference. I just have to find someone looking for the ax5 and the transfer to go to buying mt stuff.


...also looked at the 6 speed NSG370, but many have said it won't handle anything for power.

[theman53]

I found an ax-15 with a transfer case, but it has the internal slave cylinder bellhousing for 300.00. I may get it, but with everything I have to buy lately I don't have the coin. Someone needs to buy my MK1 stuff I have for sale for the last 4 months.

I wish I had JB's money..

dont we all?!?!

think of the COOL one of a kind VWs we could build with JBs money?!

the Toyota R150f bell housing has an external slave..

and you can buy adapters to go from VW to Yota..

[theman53]

I found a deal on a nv3550 I may go that route. It is almost new out of a wreck. Time will tell if I get it, but I will have almost 600.00 less than if I bought an AX 15 and had it rebuilt *I called my friend Matt who has a trans shop*. I am not in a huge hurry as I still have the 1.6L TD project to do... once I get the pieces back.

[theman53]

This is the complete junk crank out of my 1.6TD. I figured it wouldn't be too hard to cut up to use the end of it for making a flywheel spacer. This is a job for someone with a lot of time. Took about 15 minutes to get all the way through.



The idea is that I can make the spacer off of the actual crank hub. Instead of making tons of measurements I will be able to mark it through the back side and then bolt it to the crank. Then mark and drill the rest.

[theman53]

Ok, I have asked this on several different jeep forums with no answer. Here is the deal:
I have a 2002 NV231 transfer case in this wrangler with a 21 spline input shaft. This 23 spline input is for sale http://www.ebay.com/itm/180984577476?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
I will be mating the transfer to a NV3550 trans with a 23 spline output shaft. There are 4 different 23 spline input shafts for this transfer case, 2 different lengths and 2 different bearings...........What I need to know is if any of you know which input that is 23 spline will work with my parts? If any could help that would be great. I have local yards with jeep stuff so I think I could find one cheap and easy, or go with the ebay one that is pulled, but I just need to know what will work or not.


EDIT: Just found this, still am unsure of what I could get, but at least I have the differences laid out plainly. I should be able to do it once I pull the unit from the jeep now...at least. From what I gather it will be a late 23 spline with the narrow bearing and long input. Still if anyone knows what is up and could tell me I would take that.
