TWIN TURBO CONVERSION is complete
The car is a 1990 300ZX 2+2. It was produced in the first production run, and came with a slow 220HP naturally aspirated engine.
The car now hosts a 1991 J-Spec Twin Turbo engine and tranny...upgraded to Stage 4+ and delivering 450HP.
This site documents the major steps in the conversion process. I hope it is interesting to all...and useful to those who desire to convert their NA to TT.
LIFE IS SHORT...BOOST HARD!!!!
