My son and I purchased the turbo diesel kit from Rocky Road. They talk a good line and the website looked good. Based on a few earlier purchases of parts like bumpers, wheels and 2 lift kits, we bit. It took 6 months of hounding them to finally get all of the parts. The book of instructions is out-dated. (Rocky Road said they had a contractural agreement with Keltec to reproduce it exactly as Keltec made it - so we were left to "guess" at what their new procedures were.)
The engine-trans adapter had holes slightly mis-aligned - caused a mess trying to get it hooked up. The trans pilot shaft conversion instructions left a lot to the imagination - tools and parts were referenced as being "in the kit" but no longer are (but they don't tell you that!) We had to purchase a long list of extra parts that could have been better described before we bought the kit. Some of the parts are totally unidentifiable as shipped. (I sent 4 emails to the owner of Rocky Road, asking for help, offering to send pictures of the parts that didn't make sense, etc. but never received a response.)
Thank goodness I discovered Jeff at Acme. He helped (for free on the phone, I incredulously learned) me to take a more common sense approach to the re-power operation - shared how my Samurai radiator was absolutely not going to work and that there is a much better way to plumb the cooling system than that described by the Rocky Road kit/book. Like using radiator hoses instead of copper plumbing fittings! - what a concept.
There is more, but you can ask me individually if you want. This seems long!
Bottom line - we are just at a year getting it done (week ends were severely limited) and may actually fire it up this week-end.
