Question, how about ge block with gte head and gasket ge wiring harness and do the gte ecu how we'll do you think that will work, because I really would like a ffim but would like it to be like stock, let me know your imput on this

make sure you use a thicker gauge on the few power wires and ground wires that have a thicker gauge from the factory. there are only a handfull of them they need to be thicker, just flip the ecu over and you will see them.
Drift 101, that setup would work quite well, and is recommended if you want to use the TT intake manifold on your setup.
The head can be costly though, but if you are going to tear down to do the headgasket you might as well put back on all the gte stuff instead of the ge stuff if you have it, and it may require some other small mods but it has been done before and is covered in some thread its not too bad.
Do realize you may have to change out the oil pump to a TT unit then, because you will have the 2 cam sensors on the head and no distributor, so you will need a real crank sensor. If you are 96+ you may already have it take a look for crank sensor wires (a pair of the) coming off your oil pump.
If you don't have the oil pump,you may want to consider sticking with the stock intake unless you don't mind doing all that work.
I wish I had gone with a ge oil pump with the crank sensor (98+ vvti definetely has it, 96-97 maybe), but I just replaced it with a stock unit.
DO NOT EVER USE A GTE PUMP ON A GE MOTOR. it will result in too much oil pressure, and you will be popping front/rear seals continuously.

Well my car is a 96 but I'm getting a ge motor cheap from a buddy that was in a 93 I think my plan was to rebuild it anyway I think he said it was starting to knock, so I will be doing a compleat rebuild, I have been a Nissan tech for years now so rebuilding motors is not an issue I have built several sr20dets, this project I plan will take me some time to compleat so if I can use the gte head and wire it all up after that's what I might lean towards it will still be cheaper I think in the long run rather than doing a usdm gte swap plus they r hard to find I have seen a head for about 500 no cams not a bad price or find one that needs some work, trying not to go crazy but yet have a fun car that's reliable plus I wanna beat up on some of my buddies with built evos lol

The gte oil pump provides more pressure for the oil squirters which is why it shouldn't be used on an GE motor, but it has the crank position sensor on the oil pump. If you want a crank position on the oil pump you would need a 97 sc300 oil pump ( maybe 96 as well not sure since I haven't seen one in person) and the crank timing gear so you can run a Tt head.

Jwin is correct, you always match the oil pump to the block with 2jz's.
If its a gte block, use a gte oil pump (they all have crank sensors mounted on them)
If its a ge block, use a ge pump (96+ have crank sensors on them).
The only thing I am not positive about is the crank timing gear. I want to say the GTE and the VVTI-GE are different, but I am not positive. the 96-97 crank timing gear your guess is as good as mine but I would guess the same as TT cause the distributor is still there and the ge and gte pulses are the same.
hopefully someone has seen these different crank timing gears and can chime in.

The crank timing gear you have is the vvti gear which is a 36-2 meaning 36 teeth 2 are missing.
The TT one uses one where there are like 12 teeth.
so 96+ must come with that 36-2, so you would need to replace yours with the 12 tooth GTE crank gear to use it with the stock GTE or GE ecu, otherwise it wont work without the distributor. This is still much easier than having to replace the oil pump for 96-97.
Keeping the distributor really makes things much easier, but if the motor is out I say go for it, you aren't going to want to do it later.

Ya I'd like to try and make it as much as agte motor I can with out spending all the money on a swap I have built many motors for cheap finding the right parts at the right time, I work for a Nissan dealer so I get a discount also at our local Toyota dealer so it won't be to bad getting some new parts
