Throttle Body
Oil Pan (going to dry sump)
Fuel Pump, Rails, and Injectors
ECU

I want to also raise the red line to 8,000 but im not exactly sure of what that would entail...

This is my first engine that is being built for drifting and if anyone has any advice on do's and don't's on making a drifting engine it would be appreciated

DOs:

1. Imho, do start with a 2JZ-GTE instead, if you're certain that you're going to turbo it for sure. What posessed you to start with 'yota's de-tuned version of this incredible engine????
2. Figure out your max rwhp goal (post-turbo) before you buy anything or do any mods.
3. Keep your rwhp goal small, if you don't want to deal with turbo lag while drifting. There are reasons that you don't see many 2JZs drifting (especially on short, tight courses), and one of them is having to deal with turbo lag.

DON'Ts:

1. Imho, don't start with a 2JZ-GE, if you're going to turbo it for sure. What posessed you to start with 'yota's de-tuned version of this incredible engine????
2. Don't switch your pistons until you know your rwhp goal. The oem pistons (even the relatively wimpy oem 2JZ-GE pistons) can handle a lot of hp compared with other engines.
3. Don't switch your cams until you know precisely what your max rwhp goal is.
4. Don't try to run the same cams both non-turbo and turbo.
5. Don't try to run the same pistons both non-turbo and turbo.
6. Don't decide to change your intake until you know exactly what your rwhp goal is.
7. "" for the throttle body.
8. Don't decide what fuel pump or injectors you're going to run until you know your exact max rwhp goal.

QUESTIONs:

1. When you say you're switching out the head, what are you switching it out to? A 2JZ-GTE head?
2. What is your rwhp goal?
3. What compression pistons where you thinking of getting?
4. What duration of cams were you thinking of getting?
5. What size of injectors were you thinking of getting?
6. Isn't an ES250 a bit too heavy to drift competitively?

ANSWERs:

1. To raise your rev limit to 8K, you'll need aftermarket valve springs, titanium retainers, and a modified (or aftermarket) ecu.
2. You'll also need that aftermarket ecu to control your larger-than-stock injectors.

COMMENTs:

1. That dry sump system sounds cool (expensive too). Please post pictures of this modification, since it is somewhat unique.
2. Be very aware that if you try to run this engine non-turbo, and then turbo it later, you'll very likely have to re-do all of the engine mods at that time.
