your going to need to feed the injectors, so either a Denso MKIV fuel pump or 255 lph Walbro should be in your tank instead of stock. Not familiar with the turbo or e-manage ... so cant comment on that, but I assume your already addressing the stock AFM issue.
When I planned for 400'ish rwhp, I considered this path...
- feed it... injectors, fuel pump and fuel control...
- Hold it... strong engine (2jz is pretty damn strong if well maintained, believe it is metal headgasket from the factory)
- Push it... the turbo should do the job
- Let it out... the exhaust should be 3" turbo-back.
Your parts list is pretty short, so I assume that you are considering most things properly.. but thats just an assumption. Should have no problem providing you deal with fuel cut (sorry not sure if that is an issue with a 2J.. I run 7M), your tune (most critical part is making sure when you add the power you aren't killing the engine.. tune is very critical), fuel feed and exhaust.
thats my 2 cents, but I am not a mechanic, nor am I hugely familiar with 2jz.. I just happen to live really close to you.. lol.
