+1 for VP Bilberry at 10:1, used it for years with no issues. Always later used car shampoo on the wheels after washing the car to get rid of any last remaining product.
i think it would be trick to see a clean 350z, look inside and see a 370z dash, steering wheel, clocks, centre console and door trim panels. a dash looking like its from a different manufacture will look stoopid imo.
TopGear test track:
Nissan 370Z 1.27.5
Ford Focus RS 1.29.3
No Z33 times to go by, but how far behind a stock Z34 would a full bolt on/uprev'd 350z with grippy tyres, uprated arb's and braided lines be? Not much if at all.......
These cars have a maf, not a map sensor so I'd be looking towards the crank sensor. My thinking is that would causing starting issues as the ecu wouldn't know where the pistons were in relation to the cams/valve timing for its spark signal.....
