I not sure about the amendments as I am not that far into it at the moment. Check out LocostUSA.com and search for Lima, there is a lot of info regarding the Lima engine, and probably info on the T5.
I hope this helps.
I hope to be starting my build very soon as I am still stuck for space at the moment.
I have just got my Lima engine with the 16v Volvo head running and I have to sort out the MS2 system yet. I have it installed in my 1986 XR4Ti. Once its sorted I can move the XR outside, then I can get into the build etc.
cheers,
Bill.
