Hey guys,
I have a navy blue 240Z that I purchased from a friend of a friend.
Originally brought with blown head-gasket I drove it with the stock L24 and flat-top SUs (
) until the SUs decided to develop a flatspot from between 1% and 80% throttle. Holding the throttle anywhere inbetween those two resulted in massive overfueling, a black plume of smoke three lanes wide on the freeway, half a rear muffler and a subsequent police detective motivated pull-over.
After several trips to Ballarat going 100->110, clutch, roll, repeat, I sourced a supercharged L28 replacement. After some clutch dramas during the install I drove the car like this for 6 months or so while I gathered together parts for a turbo conversion.
Then 6 months ago (ok so it might be more than 6 months), after breaking the gear selector linkage on the 280z 5-speed in there I took the car off the road to do the conversion.
