I used everything you mentioned plus new injector connectors with pigtails. Also before this modification, I installed a walboro fuel pump.

You'll need a head and a fuel rail. Maybe some bolts.

Here's the shopping list if you want to do it all properly:

550cc injectors + clips (there are adapters, but most end up soldering and replacing)
Lexus AFM (blank casting works fine, the electronics from your existing will drop in)
Adjustable fuel pressure regulator
Fuel pump (Walbro 255lph or equiv)
J-tube drill out or bypass
Wideband O2
Apexi SAFC or equiv (to do some slight fuel adjustments usually Lexus AFM + 550cc combo runs fairly rich)

Fuel pump relay mod will help if you want to nail down tuning a bit more so you don't have a spike when it switches voltages.

This could all be found searching pretty easily, it's been covered time and time again :icon_razz
