TDI into Jeep Swappers links

[N2TOH]

First off, I take my hat off to you folks who take the path less traveled.

Here is a short list of links you should consider for stuff that will help your project along.

THE MOST AMUSING THING IN THE WORLD WOULD BE TO DO A FACTORY LOOKING SWAP AND SHOW IT TO JEEP!

http://www.novak-adapt.com/catalog/electronics/tj_xj_crank_position_tach_emulator.htm (Please let Eric know why you would like his converter box, his company deals only in Jeep products.)

http://www.davco.com/DFP_biodiesel.htm (I used the older 234 filter in my B4 Passat, they are very cool)

http://www.jdjeeps.com/crankshaft.html (just another reference to keeping the factory computer happy)

http://www.dieselcraft.com/engine-oil-cleaning.php (I would have installed this in my Passat if I could find a place to bolt it)

http://pabiodieselsupply.com/shop/oil-centrifuge-55gph-p-347.html (the low buck option if your willing to fab your own mounts)

http://www.novak-adapt.com/knowledge/465_to_amc.htm for use with Lakewood RM-4082, maybe not confirmed.

a quick google for "jeep hydroboost brakes" also might be eye opening.

A General purpose duel pattern GM/Chevy adapter would be cool, in say an S-10 or K-5 Blazer.

EDIT~~~ May/18/2012 condensing the links.

LOCAL policies governing gasoline to diesel engine conversions, some places are very strict and others are so lax they are contrary to Federal requirements.

Pennsylvania seems to be pretty liberal in what they allow on their roads. for reference only is a link to a shop that does 4BT conversions. http://www.jeffdanielsjeeps.com/jd/diesel.ashx when contacting them I was informed it is a non issue, just a matter of scheduling a special inspection to verify that it is in fact converted, and the formality of submitting some government paperwork that changes the title and registration papers to reflect that the vehicle now runs on diesel fuel.

New Jersey = Unless it was a factory option, forget it. it's not worth the stress and aggravation.

bellhousing update

I found different specs for the same part number @ http://mothersperformance.com/i-713...ing-rm-4082-lakewood-mothers-performance.html

Package Dimensions: W18.0000” x H7.2500” x L18.2500”

I'm gonna guess that the 7.25 inch dimension is spot on for most 4 and 5 speed transmission input shafts.

Marshall's Industrial, for bellhousings and lots of good technical data

I bought their VW919 Flywheel Housing and modified it for my application. Great company, ships to the US fast and at a good price.

Cool housing, how much was it?

I noticed your location is California. My assumption is this is not a street legal rig, and will be trailered to and from off roading locations. If i could figure out a way to satisfy emission requirements to make it street legal i would toss the 4.0L in my TJ in half a heart beat.
Is my assumption correct?

 

[N2TOH]

while not living in CA myself I have heard that Diesel conversions are exempt from the smog checks.

Here in PA after the conversion work, has been conpleated it's just some paperwork and a visual confirmation.

Diesel Swap in California

These are guidelines, and cannot be taken as real technical guidance. Lots of holes subject to interpretation.
http://www.autorepair.ca.gov/80_BARResources/07_AutoRepair/Engine_Change_Guidelines.html

I've been back and forth with the ref a few times and gotten these statements:
- intake/exhaust plumbing changes are acceptable, but only as far as needed to fit the application (can't race-pipe it)
- all cats and mufflers must be retained, presumably the engine's cat and vehicle muffler
- relocating an intercooler is not a problem
- All OBDII and diagnostic functions must be retained
- imported engines are ok, as long as it was also sold in the US

The smog cert is a couple bucks, during which the ref will verify the car has been converted to diesel, perform a snap test at 2-3k rpm to check smoke, then apply a label saying "diesel". It's then subject to the smog laws to the engine year diesels, which for an ALH means a visual inspection annually. You also need to supply a list of what's supposed to be there for emissions equipment, which they check against their notes.

When I get mine through CA smog, I'll post how it went. May be a while, though, I don't work too fast.

I think it cost me a bit over $500 by the time I got it here from England. I think shipping & tariffs made up about a third of that.

Thanks, good to hear from someone who has actually done this.

The BAR website "Engine Change Guidelines" says:

A federal EPA certified (federal or 49 state) engine cannot be used in a vehicle that was originally certified for California.

So I think there are quite a few years in the 2000s that California did not certify TDIs. Anyone know what years?

 

[N2TOH]

Along that question, are those year 2K engines PD designs? maybe another reason to stick with the older VE pumped engines, and just wait it out till the common rails are more common.

not Jeep or TDI related but still cool, http://www.alligatorperformance.com/userfiles/image/Installed-Oil-cent.jpg

 

[Wakem1]

Could you give me an update on how the swap/california smog cert is going? I want to put a TDI engine in an '83 cj 7 but before I make the commitment or buy any conversion kit, I want to know exactly what I am up against. And again, I am a little confused by the comments here....seems that some conversions may or may not? be acceptable because the original TDI vehicle was exempt....? I have not bought the engine yet, so I am still flexible there.

Have you done your conversion yet? And if so, what engine did you put in what vehicle? And what were the issues to get smog clearance?
