Hey friends,
I come from the land of SR20 and am buying a car with a 1JZGTE.
Can you please offer me any info and advice on these engines?
Specs, power output, turbos, best aftermarket parts (turbos esp)
I know not much about these engines and would appreciate a hand.
Thanks

~280bhp@6200rpm, 270lb-ft@4800rpm
it's a 2.5 non-sequential twin turbo, revs happily to 7000+rpm. depending on what generation 1jz you have, the stock turbos can be good for up to ~16psi.
On the standard turbos and injectors, the 1jz can make around 230RWKW (some claim 250rwkw). If you want more power than that, it's time for new injectors, new turbos, new fuel pump, and a new ECU.

that 'some' wouldn't happen to be a certain journo for Z-Z-ZOOM would it? 
they are a very strong, well built engine. the heads are made by Yamaha and some people reckon they flow poorly - but these people are generally into nissans. the 1JZ can comfortably support 500hp on the std internals with the right tuning - and you don't see too many 500hp stock-internals RB25s do you? mind you, the std turbos will have run out of steam at around 320.
peopel will try and sell you all kinds of kits for the 1JZ, but i'm yet to find a turbo that will better the GT35R - 700hp worth of airflow, and sitting on the lazy side of it's compressor map island at 1.2bar on a 1JZ.
from memory 2JZGTE injectors are a great upgrade, or you can pick up aftermarket ones from any brand in any size.
stock auto will prob let go after a decent power hike (like anything over 200rwkw).
other than that, the only other thing i can think of is swap the auto for a manual. it's a whole new engine to drive with.

You're probably looking at about 200hp unless the cars has been tuned for those injectors!!

are you running stock ecu or a fuel controller of any type
auto or manual ??
other mods to consider include dump pipes off turbos big exhaust 3inch ++(if not already) . good boost controller.and custom ic plumbing (again if not already done)
oh and ditto 2j injectors on stock ecu...= waaay rich
