Weak acceleration
Sorry about your bad engine. I would look for a used GE motor and replace it. Otherwise, replace internals but with stronger ones at the same time since your motor will be apart anyway. And you will have the option of boosting in the future.
What about bolt ons? Header/intake/exhaust/safc? These will definately help with get up and go.

OP, just get a quote to get your piston rings replaced. Then, PM CL Member 1989lexus, as i said i believe he found a 2jz-ge complete engine with only 11k on it. Then, look for other GE's with low mileage on them. Whichever is the most cost effective route, pursue it.
Then, once you have an engine that is running PROPERLY, worry about mods.
the guys engine is performing below normal. adding bolt-ons will only add stress to the engine and further his problems.

Before you do all of that, how do you know the rings are bad?
Did a mechanic tell you this? And how did he test it?
The 2J is not known for eating piston rings, especially on a naturally aspirated
(stock) engine. I could maybe see this being a bit of an issue on a turbocharged
2J, but it would need lots of boost over a long time.
The 4-AGE in my 85 MR2 had 193,000 miles on it when I blew the head gasket.
This was partly caused by a cracked exhaust manifold, which is fairly common
on these 4-cylinder 16 valve engines, and not unheard of on the 2J.
Anyway, when I pulled the head the cylinder walls were clean and smooth
and when I pulled the pistons the rings looked GREAT. I could almost reuse
them, but once you get that far into the engine, you might as well replace
them... (I'm turbocharging this car now).
To be brutally honest, the GS300 in stock form is not a neck-snapper.
Have you driven other GS300s for comparison?
I would do the usual tune-up stuff (plugs, thermostat, air filter, clean
throttle body, etc.) and drive it. Really... you almost can't hurt these
engines unless you drain all the oil out and drive it like you stole it.
The best cure for the GS300 blues is a GS400/430.
A turbo swap is possible, but expensive and tricky.
And you can't beat the sound of that Lexus V8.

i have no idea how it happend. ive had the car for almost a year. it burned oil really bad and had the blue smoke when i got on it. ive replaced all the o2 sensors and the cats. ive been running a thicker oil and havent had a problem with the smoking ever since. i took it to a lexus/toyota shop and told them the symptoms they said most likely its the rings. i should have a compression test done on it just to make sure. but other than that the only way id ever know is to tear into to motor.

with a new motor or a motor w/ bad rings, the 2jz-ge does NOT have any performance. not with 36xx lbs+.
running thicker oil is only short-term remedy. in the long term you will still need to replace the rings.

im not looking to make a race car out of it. and i know the thicker oil isnt a long term solution but rebuilding a motor is a lot of money that i kinda dont have at the moment. if worse comes to worse ill just get a credit card and tell the shop to go to town
