Oh Well, Nissan RB25DET engine as in my skyline is 9:1 and will take 1.2 bar as standard.

#1 - what's "dynamic compression ratio" ?
#2 The stock intercooler is worse than a GTA one, although it has better air flow over it
#3 The stock turbo is -worse- than a GTA one. I've got them side-by side on the shelf if you want a looksee. Smaller ceramic exhaust turbine, nylon compressor. Same inlet and outlet.
#4 better fuelling? How? Bigger injectors, yes, but if you don't hit the limit, how does this make any difference to the effect of a higher/lower CR ?
#5 Likewise engine bay heat issues..... you mean they'd rather lower the CR than cool the engine better? That's fuzzy logic if you ask me.
