Sorry John, don't get on here much! I'm not fussy about what is under the skin, in fact i love modifying. As long as the mods are executed well and improve the car then I say go for it. My biggest issue with my R32 is that I can't modify it! I think the people who have owned and put their mark on a car through it's life are as much a part of the cars story as the people who put it together at the factory. Most don't agree though looking at values of original, documented vehicles vs the modified versions.
I bought my 1600 back in 1990 as a body and parts from an engine builder who worked at HRT and then went on to work in F1 with the Arrows team. He had started to prep the car for the track but found HRT took up prety much all of his time. Not sure where he ended up. I rebuilt it back then - it's now about 30%1600 - the rest is 240K, DR30, 180B, 260Z, Hilux, R31 - even Pulsar! Mostly brand faithful, but most of the 1600 bits are gone..
I'm now giving her a refresh, fixing up the awful job I did back in the early 90's!
But hang on this is all about ADM R32's. Did you sell your Silver car? Market was looking pretty good last time I paid attention.
