new to the forum with a build in process
hello everyone on cl I'm new to forum and happy to be a lexus owner
so to start off i have a black sc300 with no motor
i really wanted to go tt ended up being out of my price range. i recently purchased a complete na and figured why not go na-t. so far i have motor , r154 trans , spec clutch , 3 inch exhaust and a 71m borgwarner turbo. i would really like to make around 550-600 rwhp i just need some guidance to help get to that point dos and so nots to reach my goal I'm new to whole 2jz and want to make power

FFIM, bigger TB, injectors, engine management, TT headgasket, TT head studs, wastegate, BOV, intercooler + piping, EGR block off plate, and a turbo exhaust manifold is all you need.
You still need around $2,500 to finish this and that's with used parts. Best of luck with the build.

yeah you can do the tt ecu mod with some larger injectors and get rid of the distributor and go coilpacks and stuff, same if you went standalone like aem v1 or v2 among others out there.
you can also use the distributor up to 600hp, some have used it for more, but the plug gap has to come down or add an ignition amplifier, etc, etc, we all just end up going coilpacks to make more power more easily but the distributor with a new rotor and cap can do it just not great.
most important thing for na-t is engine management, forget the rest of the small stuff for now its all easy. decide that and then go with the best coils that ecu can support from the start is what I always recommend.

you can either start with a new 2jz-GE harness and modify that by adding wires for all the extra ignition stuff (coilpacks and ignitor), or you can use your friends harness on your car and use TT coils and ignitor and a tt ecu. you will have to move some stuff around on the engine bay part of the harness as the gte motor has a few different things going to different spots like the cam and crank sensors are in different places.
so you can either pay 700 and rewire that harness in the engine bay, or you can pay 1-150 and add the ignition wires to that harness. Its usually only worth using a tt harness if you are dropping in a TT motor and want the twins and all the extra stuff to work plug and play. if you are going single turbo na-t then its much cheaper to use a sc300 harness and go from there adding the ignitor wires and coilpack wires, as once you modify that tt harness its no longer worth $700 anymore, and a tt harness is not plug and play on a na-t it will require some rewiring in the bay. its arguably the same amount of work or easier to just install the coil wires on the ge harness which is what me and many members have done.
