TDI(s): AHU
Default

My AHU moved a TJ with the NV3500 on 33's and stock 4.10s very easily. However it was not stock. Not sure the weight difference from the JKU. I eventually sheared all the R&P gears towing a camper out west and in a pinch ended up with 4.88's. They are a little too tall and I feel the 4.56 would be perfect. However I think these 88's would be ideal with 35's. Then again... not going to happen in a D35 either. All that to say if your JKU is at least geared as a 4.10 from the factory it should move it along a lot easier than you might think. My camper weighed in at 1500lbs and it was shocking how un-noticeable it was behind it. If anything that's more than your weight difference. Also keep in mind you have an NSG370 with a shorter 1st.

It has the 3.73's and weight is about 4500lbs but hopefully with that short 1st and the big flywheel it will pull away OK.
This is my daughters Jeep so acceleration is not the big deal, just don't want it stalling at every light.

I'm finally getting some time to work on this again and making good progress.
I'm at the wiring stage and its going OK BUT When I stripped the donor car I either overlooked the glow plug relay or forgot where I put it.
Can I just use a standard HD 12V relay instead of the stupid expensive BEW "smart relay"?
I have a whole shelf of relays in stock up to 1000amps.
I can have the fault codes deleted from the ECU when I get a tune so that's not a problem. Which ECU wire would run the GP relay and is it a B+ or B- signal?
This is a BEW, not an ALH so the pinout is different on the ECU plugs.

Randy, I'll mail you a relay for the cost of shipping if it makes life easier. I have a BEW smart relay somewhere...

Thanks for the offer xerootg but its the base and wires that have me stumped at the moment.
I will try a few more auto wreckers and see if I can find it.
I'm pretty sure I don't need the "smart" part. Next thing you know we will be riding in self driving cars!! :<(

My Jeep has 31.5's on it - 4000lbs. 3.73 rear gears. Has no problems with stalling or starting out from a light. Even pulling a 5000lb loaded trailer. Running a stock 3.7 SMF from an NV3550.

And what does the 3.7 unit weigh?

No idea what it weighs. More than a TDI flywheel. The SMF flywheels for the 3.7 are unobtanium rare now anyway. No one makes them and there aren't any NOS ones anywhere that I could find. I had to use a used one and machine it even though the FSM advises against machining them due to a convex surface or something like that.

Yes, I had the 1st 22R done back in May but then my long time machinist retired.
I found a new local shop to take over the machining but they are just now getting the fist batch of adapters built. The first ones out the door are going to be the Jeep and Ranger since there are a number of people waiting on them.
Next would be the 4 cylinder Nissan and new style 4L Ford.
After all that is done we will look at the Toy V6.

Found a local auto wrecker with an 04 BEW Beetle and got the whole engine/chassis harness with glow plug relay for $50 so I now have the proper glow relay installed.
Spent the whole weekend wiring and late in the day it came to life!
Rolled over about 8 times and fired right up. No cooling system installed yet so I only let it run for 20 seconds to be sure everything worked.
Hopefully next weekend I can get some hoses installed and take it for a run.

I was having a problem figuring out an intercooler solution for the JK and had bought a water to air unit but since this is a DD for my daughter I wanted it simple and reliable.
I found that there is an aftermarket intercooler kit for the stock JK V6 when you super charge it. I was able to duplicate that install with MUCH cheaper parts off the net.
My go-to supplier CX Racing had all the parts and installation went quick and looks good.

Also got the dlownpipe welded up.

Air2Air even on a smallish size out front will work fine especially in your neck of the woods.
