If your like me and love Jeeps but want economy your not alone.  I have been searching high and low but with little support from after market companies doing your own swap could me a nightmare! Now there is a solution…HPA Motorsports.  Hpa motorsports will be offering TDI conversions for the CJ/YJ/TJ in the very near future.  There are many versions of the TDI and if you want simple you can convert a electronic diesel back to mechanical pump injection meaning fewer wires and no computers.  The TDI typically produces 90HP/178Ft Tq which may not sound like its enough to switch to a TDI conversion. A simple turbo upgrade or intercooling can net 100-150Ft Tq so now the upgrade has your attention.  I am pretty familir with the TDI motor since I owned a 2005 Jetta PD TDI which I never got below 42mpg on average, my best tank being 47 1/2mpg. Now we’re talking about Jeeps and they are not designed to get into the 40′s….maybe the 30′s..maybe.  I am sharing a company newsletter which I recently received and wanted to share.  Also if your going to Sema the project YJ test Jeep will be there TBA.

The past several weeks have been busy ones as our team has been working aggressively to finalize tooling and fitment for the Jeep TDI conversion while at the same time, augmenting our YJ’s running gear with a variety of upgraded parts.

To ensure our YJ was up to the task of transmitting the torque and HP of our TDI swap, both the Dana 30 and 35 axles have been torn out and beefed up. Precision Gear was called upon to outfit these small pumpkins with 4:10 gears and Alloy USA delivered unbelievable axles. The quality of these parts builds back our confidence in these OEM axles.

We have made some minor adjustments to our initial engine mounts to facilitate a seamless integration with the OEM rubber mounts. We have elected to supply a ready to install flywheel along with heat shields for the starter to protect it from the downpipe. Lastly, the downpipe has been re-routed to ensure it mates with off the shelf 2.5” exhaust systems. In our case, a Magnaflow has been strapped to the underside of the YJ.

Our Stage 1 Grouping is now finalized and is targeted to the “Do It Yourself” enthusiast. Take a browse through the product photo gallery to see detailed pictures of the installation. Note: Our engine mounts can either be bolted in or welded on. The installation images showcase the installation using the supplied bolts. Minor clearancing is required on the AX-5 bell housing to accommodate Bosch starter nose

The Stage 1 adapter set is as follows:

• CNC flywheel/crankshaft adapter
• CNC bell housing adapter plate
• Left and Right Male / Female engine mount set.
• (OEM jeep rubber mounts not included)
• Downpipe
• CNC machined Starter flange and heat shields
• (Bosch Starter not included)
• Flywheel and Crankshaft bolts
• Dowel pins for bell housing
• Turbo outlet adapter

Also included is a short OEM parts list to identify starters, engines etc. required for a successful conversion.

Stage 1 package $2599 USD

Our Stage 2 package’s intake track has been finalized. An air to water intercooler has been configured to optimize the space available under the hood, and sustain charge air cooling during low speed off-road applications. With off-road low gear terrain, air to air cooling intercooling as the factory TDI’s are equipped was simply not a good fit. Using a stand alone closed loop water system, our secondary radiator, cooling fan, pump and after cooler can maintain a steady state air intake charge best suited to feed our high torque output.

Our Jeep is bound for a debut at this years SEMA show. Once we return, we will develop the AX-15 adapter for late November release.

We have been teased and teased about a diesel Jeep Wrangler for quite some time. Concept after concept emerging teasing us diesel freaks that someday our beloved Jeeps will have diesels in them. A tuner company by the name of Green Diesel Engineering may soon offer us jeep guys something we have longed for….A diesel wrangler. Yes, GDE has been working on a complete diesel swap into your Jeep or rock buggy that may be available by the 4th quarter this year. After some forum rumors we decided to ask GED about the possible diesel swap.

Here is their response in a snippet:

We are working on importing a new version of the 2.8l VM engine in the states for “kit” cars and “off-road” rock crawlers.  When the engine is finalized, our objective is to allow it to be mated to any customer requested transmission (with custom adapter plate) and to have it designed to fit any Jeep product or other custom rock crawler.  The kit would come with engine ECU, wiring harness and custom engine calibration.  We are hoping to have something available by the 3^rd or 4^th quarter this year.

UPDATE

“Thanks for your inquiry; I appreciate your interest in all things diesel. Your request for a 50-state (Tier 2, BIN 5) emission legal diesel powertrain swap kit is a long term goal of GDE. Unfortunately, the first application we are trying to import will be for “off-road” competitive use only. The engine must be used in a non licensed vehicle that is registered with a sanctioned racing organization (W.E.ROCK, XRRA, SCORE, Dakar , etc.). These first engines will be marketed to hardcore off-roaders that want the diesel low-end torque, engine braking and precise throttle control for rock crawling. The objective is to build awareness for the diesel capabilities at a grass roots level. We are still working on finalizing the final build spec of the engine, but it will be based on the next generation VM 2.8l engine. The price is not set yet, but a kit including: engine, wire harness, engine controller and calibration could be between $10,000 and $15,000 depending on which transmission is used. This would not include the cost of tranny, cooling pack, exhaust, etc. A conversion is very expensive and not appealing to the masses.

To actually have an emission legal kit, we need some massive investment, which does not exist at the present time. The diesel powertrain would need a urea injection system in the exhaust to lower the NOx emissions, this requires a new engine ECU from Bosch or another stand alone ECU to manage the after treatment. A diesel particulate filter would also be a must. An endeavor of this kind will cost ~5-10 million to sell on a small scale, under 5,000 units per year.

What’s left of the Big 3 does not seem to want to invest in diesel for the US market. I think they do not talk with people on the street or see the marketing potential if done right. The Jeep Wrangler, Liberty and Chrysler minivan diesels could all be on US soil in less than two years if Chrysler wanted to be innovative, take a risk and sell up to 100,000 diesels per year. I am not confident they want to make a profit.

As GDE grows, we will be offering other products to the diesel community and a hope to broaden the use of clean diesel in the US . If there is anything else I can do or answer, just let me know. AEV’s J8 is a good starting point and a very solid product. I will start checking out their forum.”
