1.they don't much up...you have to mod

2.Is not hard but not easy either.You will have to keep some of the stock wiring and connectors-plugs from the 7M harness,which deliver signals from the MA71 body to the systems around the engine,like PPS,ABS,TDS,Transmission signals(more wiring if you go with autotrans),Reverse lights connector,heater valve and a couple more.
You also have to plug to the 2jz motor some 7M sensors like,oil pressure sensor,2 A/C valves,and possible a water temperature valve for the gauge cluster.So you have to tear appart the 7m harness and keep the right cables
for the connectors inside the car and for the connectors in the engine bay!
After you will have to make your own harness to connect some 2jz connectors to the ma70 body connectors (mostly found under the glove box compartment were the ecu is located)...while a few wires will go to the E10
connector which is located on the stock 2jz ecu!

3.You are wrong.The R154 is oem for the 1jz but you'll need need a 1jz
bellhousing.And if you go with 2jz you'll still need a 1jz bellhousing,1jz
flywheel,1jz bolts for the bell housing,7M disc-clutch,7M mounting insulators,
and 1jz mounting brackets (for the engine).And you will have to own a 89+
mk3 supra to have the correct crossmember otherwise you'll have to get it!

4.No

5.You'll have to use the OEM specific ECU (1jz engine goes with 1jz ecu and
the same goes for 2jz)...or you can go with an aftermarket ecu !

6.Some guys or sites can help you with that...But still depends what you'll
get (USDM 2jz, JDM 2jz, and 2jz from Aristo which is only JDM have some
small but important differences,if you go auto or manual or even 6 speed
getrag mk4 trans).I heard Arnout from Holland can do the harness for plug & play.

It's up to you

thanks supraclaou......and i have tried the search buttom all its giving me is this bill crap about sells and other peoples swap.....like they really tell u "i got this engien harness from the shop." or "i did the harness myself." NO all they say is "i got a 1jz or 2jz and its freakin fast check out my HP AND TORQUE CURVE"...........so i found the most easiest way to find something out is to ask the question......not spend hours on the CPU searching and searching for nothing.....but yeah thanks for the tip but like i said i tried looking....couldnt find so i asked the question........im pretty sure there are people out there askng the same questions......

Yes it is, scroll down on the first link given above, there is a new location.

Youve got to learn some patience, and try looking harder. All the info is out there somewhere, it just depends on how hard youre willing to look.

Dont worry man. I think search designers are the dummest living thing on earth. If search were so great we all be using it but guess we all arnt. If you have question just ask away. Some people just say search to say it but a few will always take the time to answer your question.

2JZ swap is a pain in the butt for the most thing its because of the wirering. The motor itself with the right mount will bolt in but the wires and bell housing will be needed. Also an another advice is if you are going to do a 2JZ, take the time to check the block over and mod what ever you can before putting it in. Saves the time later.

Not true - the amount of help the majority of us are willing to give someone, is directly proportional to the amount of help that the person has already given his or her self.

We tend to not spoon feed things around here ;)
