i would say the availability of this differant engine is also an issue.... alot of pl love to have bigger displacement + turbocharge however anything above 2500cc is already killing for some pl in terms of annual roadtax.... my 1jz cost me around RM890 for roadtax alone...
having big displacement NA is fun wid the higher compression ratio, your power is just on tap. where else having a low comp turbocharge the fun only begins when boost came in. and if u are having a big turbine and if u operate below the boost kickin rpm u will just feel 'kosong'....
but i do love 2jz wid a big single... yummy....so for my own taste of mod, i will prefer doing a fairly sized turbo that could max out the stock 1j internals and if it doesnt feel but kickin enough, then move on to 2jz bottom....
bigger than 3.0 i have no idea... never had the chance to sit on a performance car wid such size of displacement
