I will start at beginning, I have NA supra and have removed engine to do NA-T build after noticed had knocking noise.
I have removed engine and initial idea was to do fully forged block, but reckon will cost about 4K and was thinking does it make more sense to buy pre-built TT block from Whifbitz.
Question is how much power can the standard TT block take with NA head?
I am also running Nos system that's why thinking forged build be best, but thinking 600-700bhp is realist goal as want to have very fast road car that can use on strip and track, but don't want to have to take block out again in few years.
Also on another note I did suspect little end had gone from rattle as noise was bottom of back on engine but when took clutch off the flywheel bolts were only finger tight, so now think that could of been noise just hope hasn't damaged crank.
