I think 2JZ is suits for boost up stage.More power and less money spending.But 2JZ still not the best series engine for Toyota,hee.
Weak point:
1. I think who play 4x4 should knw this low rev engine behavior.
2. Engine heat,normal cond. is 90cel and hot cond(Malaysia) 100cel is common.Plus front mount
I/C and oil cooler might can reach 120cel.
3. Original ECU is detuning the power band base by engine temp.So need to get rid of the ecu if
you want power.But engine will be less reliable.96-97 VVTi engine will be more hassle
to tune.
4. 2jz really have less aftermarket choice in all range.(myb becoz the engine already
bullet proof)Anyway NAPREC claim 2JZ block is bit weaker than RB26DETT.
every engine has it`s weakness.All is depend on your pocket MONEY. I heard you can`t change name for different maker between engine and chassis at Malaysia?dunnoo~
