why post a reply like this when you have absolutely no idea .
And obviously have never attempted either conversion
i must have read this BULLSHIT a dozen times some dickhead claimed this once so every appoints themselves all knowledgeable
and repeats it all over the forums
for starters the ACTUAL length difference in the block is bugger all the 1jz pulley accounts for the majority of the difference .
the weight difference is a joke less than 20 kg (yes ive actually weighed them both)
the 1jz gearbox is 16 Kg heavier so the front to rear weight distribution is almost equaled
the actual mount position of the 1j allow it to be positioned more rearward and lower than a 1ggte
Not only is it a better fit but the car will actually handle better with a 1j in it .mounted in this position
yes the 1j is more expensive but with 1/2 cuts selling for $2000 they arnt much dearer .the whole conversion would be no more than $1,000 dearer but eh car would be 2 secs quicker 0-100 and 1/4 mile
considering the number of 1j conversion around i cant see how the number of 1ggte conversions done makes this easier .The 1ggte conversion has less involved but can still be done by even YOU
