    Hi Justin,

    I'm at around the 500km mark and was pondering a turbo conversion with a mild boost but was a bit concerned I was about to make the 4BD1 into a hand grenade...would it be fair to say I'm worrying a bit to much about this ? I'm not sure how many NA motors have been turbo-ed out there and how safe it is to turbo an NA unit with that many km's.

    Just do it, and keep your EGT to a lower threshold if you are concerned. 600deg upstream will be a very safe level and give you good performance. I did mine at around 480k, but it got some huge caning, towing and "testing" at big fuel settings. Took quite a while to kill it...

    I’ve gone with the KLR, I know it’s cheaper if you source all the parts yourself but it seems like a pretty good deal that they’re offering with everything in one box. If it wasn’t for all this Covid business I probably would have paid the extra and got them to fit it all up.

    My county has one on it, there is a write up on the build on here by the previous owner many many years ago, he installed it himself. But looking at the 'kit' it all looks basically off the shelf from isuzu and garret
