hey, just got a quick question, i am looking for more power from my SJ410 and have heard people talking about a vw diesel engine and was just wondering how hard it would be to put one in my SJ?? any info would be muchly appreciated

If you have had you SJ410 for a while, then you know they don't match up with many Sammy parts.  That being said, there's no swap kit for an SJ either.  I had a SJ410 for years and it could reach 65 mph on the high way and it went plenty fast on the trails.  I'd stay with the might 1.0. 

A guy in the UK has been through no end of problems with this swap. Nothing wrong with the swap itself but finding someone with the knowledge to do it properly cost him 2 engines. I know he highly recommends these people. They spotted his cooling problem instantly (plumbed up wrong!) and have been very helpful.

You would need to swap in a 413/Samurai gearbox and you may well find that the 410 axles aren't up to the job. If its a pre-85 410 then will need to fit a bodylift or modify the trans tunnel.
