why not 31? :3d_frown: HA!

but seriously psi doesnt mean shit! 30 psi on a 35r is not going to be the same a 30 psi on a t76! thats your first mistake sir.first you need to get yourself a power goal and ask or SEARCH a way to acheive said power goal on a 2jzge na-t.which i might add is the same thing im doing in my turbo mk3 and my power goal is 500-530 rwhp :evil2:

Why do you want 30 psi? And what turbo do you want to do 30psi with?

We need information from you, good sir!
1- How much money do you have to spend
2- How much power do you want to have in the end
3- How much work are you able to do (has to be top-notch quality work, not backyard stuff)
4- How long are you able to wait for this to come to fruition?

Reply with info and we shall see what the general consensus is. Until all of that info is public we can't tell you what to do. (more will be needed as well, that is just barebones basics)

imagine if this was posted on supraforums.com this would have 5 pages of flames in like a solid hour lol. but on serious note, do a little research, and figure out what you wanna do with this car. drag? dd ? 30psi with any turbo is alot of boost with any turbo.

1- How much money do you have to spend
**Need For Us To Help You.

2- How much power do you want to have in the end
**Need To Know To Select Turbo. Usually With 30PSI, Ball Bearing Is Preferred.

3- How much work are you able to do (has to be top-notch quality work, not backyard stuff)
**Need To Know.

4- How long are you able to wait for this to come to fruition?
**Important If It Is Your Daily Driver

You can run 30 PSI on a 60-1 and 30PSI on a 80MM....both are NOT the same PSI, so the way to select the turbo you need is to know the power level you are looking for.

You will also need fuel for this power level as well.

I think he just wants to run 30psi. Specifics dont matter as long as its 30psi.

Yeah stock NA fuel pump with stock injectors.. 30PSI

Different turbo's flow different lb's per min so 30PSI doesnt mean shit.. You can make 400HP on 30PSI with a small turbo or 800HP on a big turbo on 30PSI

Easiest Way To Those Numbers...

Do a 2JZ-GTE Swap, No NA-T.

By a Ball Bearing 70MM Turbo.

Upgrade Your Fuel System To 1000CC Injectors And Fuel Rail And Fuel Pumps To Support.

Buy An AEM, Haltech, Motec Or Stinger Standalone.

Build The Head, Cams, Springs And Retainers and over size valves is optional.

Throw In A Clutch To Support That Power, Twin Or Triple Disk.

Go To The Dyno, Throw In C16 And Tune.

That is how you make the higher end of the power you are looking for reliably and safely. You don't want 800CC injectors for 750HP. I don't like running my injectors at their limit, people use 80% as a rule of thumb of what you should not exceed. I use 70% for my calculations because it makes no sense because you can have proper idle with a good tuner and sequential injection.

None of this will be cheap. The price of a twin disk is $2,000 plus.

Ok, I'm going to be as nice as I can be. I can count on one hand the high school kids that could handle 600HP. All of them have been racing since they were kids on motorcycles and carts. If you own a MKIV Supra with a 2JZ-GE, you have more to worry about than just the engine. Off the top of my head:

- Transmission is either an auto or W58 5-speed. Neither will handle 600HP. Built auto or a V160 6-speed swap: couple grand
- Brakes brakes BRAKES. Non-turbo MKIV's have smaller brakes, and if you have 600HP you NEED to stop just as fast if not faster than you can accelerate: couple grand again at least.
- Wheels/tires. Gotta put the power down, right? Varies a lot, but a grand is average IMHO.
- Turbo/fuel/exhaust/engine/ECU/tuning/intake/clutch/etc. I can see an easy $10K there, if not far more.

The main issue is you're starting from an NA car. If you had a Turbo-6 speed car, you'd have a good leg up on getting to those power levels.

Wilwood brakes are top of the line and cost less than Brembo but they are still a couple grand for the front and rear. 10K is about right for the price of this power level and doing it right.

Swap a diesel engine in. You can run 60psi all day long.

Remember: Boost is a measurement of resistance.

A R154 will need a rebuild with new bearings, seals, synchros and Marlin Crawler parts to handle that power reliably.

If you're just going to immediately go single, I disagree with the post about going GTE instead of NA-T.

2JZGE with nothing but a thicker headgasket will handle the power you're looking for, but the tune AND octane are crucial, no detail is to be ignored.

My reason for telling him to go GTE is because the OP, no offense, sounds like he does not know a lot about this so the lower compression would be a plus in this case. You don't think so?

Totally get the same vibe, so maybe we should offer another solution:

OP:
You're in highschool, and you want to go from a 7MGE to a 700+whp 2JZ in a 23 year old car?
a) You posted this in the wrong section, thats why people think you have an N/A MKIV
b) Your going to need to have a lot of money, more if you don't spend a multiple hours night reading this forum for a solid year to learn more about what you want to do... because you're going to pay someone.

Basically, if you're going to pay someone, go 2JZGTE beacuse you're obviously made of money and want it now.

If you're on a budget, go 2JZGE and save up about $10k (realistically) and frequent this forum.

I have a better solution.

Stay in school, get good grades, read the forums until you understand what it takes to make this power and HANDLE IT and then do it yourself.

Why do high school kids think 400HP-500HP-600HP-700HP is a joke to handle and especially on a stick shift car where there are so many things that can go wrong. Have you ever thought about missing a shift and going into a lower gear, then your wheels lock and your car kicks sideways?

Trust me, it is not fun and will make you get an adrenaline rush if you survive...

A kid is in coma because on New Years Eve he was racing on the road and crashed the car. They had to use a saw to cut the roof on the Supra to get him out and the car caught on fire. It had a 2JZ with a 70MM but we don't know the power level but with that setup, it must of been upper 400HP to 500HP, maybe higher. Think about that...

Saying that is no way of me wishing bad on you but just telling you that RWD+High HP Supra+Young Driver = Danger.

Dude if your asking a question like that then your probably not well suited to try and build a 600whp. No offense to you but coming from another kid (im 16 too) you have another thing coming to you. Before you ask another question like that try doing some research. The knowledge on these forums are abundant. Do some research and you should be able to justify what you will need to build your car before you ask a question like that and get flamed by a forum. Your lucky supramania is a pretty nice forum unlike supraforums haha

waking up a dead thread--- turbo tesla did you ever find those dimensions to those mounts? and 400 is alot of hp. thats like 400ftlbs of torque equvilent to whats in diesel trucks....but in a 2dr car. throw a set of bearings in your 7m and maybe rings and na-t it. then youll understand boost,fuel management,blown hg so when you spend big money you dont learn the hard way. plus youll spin out without flying like a rocket if u go spinning out of control into the other lane :) been there...done that

good luck and school means alot..wait to hear what you decide to do!
