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.

1. I would have liked to start with a 2JZ-GTE but i couldn't find one unless i bought engine assembly with turbos and in most cases the entire front clip from some other car using that engine (whether it was a Lexus or Toyota or whatever) and I didn't want to spend the money that a 2JZ-GTE cost with turbos and acc. (my budget is small at any given time but growing larger with every paycheck) or on the entire front clip.

2. My rwhp goal is 600

3. Is turbo lag going to be that big a deal when in the higher RPM range that I am assuming you should be in when drifting?

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.

1. I was planning on swapping most of the parts that seperate the 2JZ-GE from the 2JZ-GTE even if i was to get the 2JZ-GTE.

2. Im not worried about the rwhp goal for my pistons, it was one of your previous replys that said the connecting rods are good to 850 rwhp so im assuming the pistons would be fine for the 600 rwhp i want, but im worried about what will happen to them if i raise the redline.

3, 6, 7, 8. 600 rwhp

4. I wouldn't run the same cams for an n/a or a turbo engine

5. Same for the pistons.

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?

1. I want to switch out to an aftermarket replacement for the 2JZ-GTE head, but im not sure what company but i am currently researching that

2. 600 rwhp

3. I was looking for some advice on this but i was thinking somewhere between 10-12:1 comp. ratio so i could get more hp straight from the engine and keep the turbo smaller, and yes i want to go single turbo

4. Im not exactly sure. What i've narrowed it down to so far seems to fit into the category of "semi-rough idle". In other words fairly lumpy but so that it won't stall if i don't put throttle into it.

5. I have no idea except that they would be bigger.

6. It is on the heavy side but most of the es250 is getting stripped out and I am tunneling the body and with the dry sump system i can greatly lower the center of gravity and I am widening the wheel base so although the car is heavy with all the different mods it, in theory, is managable... If there is something skewed with my thinking let me know.

2. You'll also need that aftermarket ecu to control your larger-than-stock injectors.

1. Although I didn't state it the titanium springs/retainers were already planned along with the after market ECU. Any good companies to get the ECU from?

2. Good to know, thanks.

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.

1. Definately, pics will be posted as project rolls along.

2. I was planning on running it non-turbo but only before the engine mods were put in... I know I'd need a 2JZ-GE ECU and then I'd have to get the new ECU when mods are done, but I need a car to drive sometime during this time otherwise I'd go crazy...

Also, is 600 rwhp feasible with a n/a motor on pump gas? I've been tossing around the idea of keeping it n/a but am not sure its worth it. And a couple things i forgot to mention in my initial thread; the car will be a purpose built competition drift car but is going to be street legal and needs to be able to run on pump gas.

Thank you for your reply.
