I agree with warmkop – you’re neighbor is completely full of it. Obviously he knows nothing about the 2jz-gte – the oem 2jz-gte internals are very reliable up to 1000hp (of course, using race fuel and high boost from a large single turbo and large fuel injectors).
However, your neighbor was correct that you can get about 100 extra hp off stock with simple modifications. Would you consider this as a starting point?

Wrong. By saying this your neighbor proves he not only is ignorant about the 2jz-gte, he’s ignorant about the Mkiv Supra Turbo as a whole. The oem rear axles are good to over 1200rwhp. Yes. That is not a typo. 1200rwhp. Really. Let me know if you’d like me to help …um… educate your neighbor about the legendary Toyota Supra Turbo. J

For 600rwhp (6spd), your neighbor is also NOT correct about this. The oem intake plenum is good to about 750rwhp (translation 882hp at the crank. Again – Really and 100% for sure.).

For 600rwhp (6spd), your neighbor actually IS partially correct about this. The oem fuel system is only good to about 525rwhp. However, the 2jz-gte only has ONE fuel rail, and ONE fuel pressure regulator. J Also, these are not the only components that need to be replaced for 600rwhp. For 600rwhp you would need (As warmkop mentioned) either a complete aftermarket fuel system (which includes these items and many other items that are required) –OR- a large methanol injection system that will not only supply charge-air cooling, it will also supply about 75rwhp of additional fuel.

Agreed. (Finally!) Score one for the neighbor. The oem 2jz-gte clutch is only long-term-reliable up to about 400rwhp. What’s that - 10 completely wrong, and only 1 right so far?

Wrong. The oem flywheel is fine up to 750rwhp or so, together with an appropriate clutch.

Wrong. The oem driveshaft is fine up to 1000hp, as long as you don’t try to drag race it with R-spec roadrace tires. ...and even then, the real problem is the subframe bushings and not the driveshaft.

Again, he’s completely full of crap here…however, he’s not nearly as far off base as the Sonyps307 dude.

WELL he’s partly correct because there actually is a set of mods that can get you to 800hp and much more if you want…HOWEVER that list of mods is definitely NOT the list he gave you. Instead, start with warmkop's list, and let us know if you have any questions.

Oh, last but not least you said:

Now I am perfectly happy with how it is and how it drives since it will be a daily driver

...please note that in general, the more you modify it the less reliable and the less comfortable it will become. Modifications are essentially a partial reengineering an entire (currently-working-well) mechanical system. Well-paid and well-qualified automotive engineers from Toyota designed everything in the Mkiv Supra Turbo to work together as-is. If you mess with one thing it can affect dozens of other parts of the system. Small modifications will likely only have a small overall impact. More extensive modifications definitely will have a more extensive overall impact. Put another way, you can get a "1001 hp" Bugatti Veyron from the factory, where the entire car is already properly engineered to manage that 1001hp...but it's a $1M+ car. Although some of that price goes towards profit, most of it actually goes towards covering engineering costs and materials. As you begin to modify your Toyota Supra Turbo, please keep all of this in mind.

All I said was there is supra running 1000hp+ on pump gas and u can get 600hp with a bigger turbo and more fuel. Of course he will need things like cams, head work, meth injection, bigger fuel injectors, bigger turbo, ecu, etc. what I was getting at was that the 2jz stock can take 1000hp can it not?

   ...There is NOT any Mkiv Supra Turbo with a 3L 2jz-gte running 1000hp+ on pump gas. Prove it if you think I'm wrong. Post the information about that Supra right here, in this thread.

   Actually, what you posted was this:

   ...which is absolutely NOT accurate or practical (see my post above for an explanation)...and therefore it is simply more of your bad advice.

   You did NOT mention anything about "meth injection" in ANY of your prior posts. If you're running meth injection, you're NOT only running pump gas. Warmkop told Mmeyer183 that you were wrong right here...and here...FOUR DAYS AGO!!!...and you still didn't do anything to fix/retract your misinformative posts, or post anything new to clarify your obviously-bad advice, until I called you out on it today.

   You do NOT need aftermarket cams or any head work to make 600hp with an oem 2jz-gte. You also do NOT need aftermarket cams or head work to make 600rwhp with an Mkiv Supra Turbo 3L 2jz-gte. This is yet more misinformation and bad advice that you just posted ... that could also result in Mmeyer183 wasting even more $$$ on unnecessary modifications.
   
   Your feeble attempts to dig yourself out of this hole are only making the hole deeper. You may (or may not) actually know a thing or two about base-model 7mge MkIII's (i.e non-turbo / 'normally aspirated'), but you obviously have a LOT to learn about the 2jz-gTe. Maybe it's time to quit trying to pretend you know anything about this topic, and just sit back and read and ASK questions so you can learn something first.
   

5. ...what I was getting at was that the 2jz stock can take 1000hp can it not...

   Don't try to change the subject. Your prior posts were all about what can be done "on pump gas" alone.
   

6. Sonyps307 (again) STOP posting lies and bad advice. This isn't about anyone getting upset. This is about you posting advice that...if followed...would waste the time and money of the unfortunate people who might actually believe your lies and follow your misleading advice. Bad advice in a forum like this could even result in injury or loss of life. What if Mmeyers183 followed your idiotic advice to build a 1000hp with pump gas, and the resulting fuel detonations blew chunks of piston into the crankcase...which in turn locked up his engine while drag racing? Would you even care that your bad advice could lead to his injuries and wrecked Supra?
   Vehicle modification is not an area where guesswork by ignorant amateurs can be tolerated. Give that some thought.
7. Sonyps307, unless you can produce evidence of this 2jz-gte Supra that by some miracle is actually "running 1000+hp ... on pump gas all day", do not post any more in this thread. If you post anything other than direct, specific information about that magic 1000hp+ pump gas 3L Supra in this thread, I will immediately delete your post from this thread AND suspend your membership in this forum. Your posts have already made it crystal-clear that you have absolutely no information of value to contribute to this thread. Consider this your final warning regarding your posting of misinformation.

Last but not least, Mmeyers183 - apologies for the digression. Please refer to my previous on-topic response, and let us know if you have any follow-up questions.
