high powered NA!

Yeah pretty much. Rebuilding a 7M-GE with turbo pistons you might as well just do the motor swap. Or a 1JZ.
What are your goals? There are a couple of different levels of "max n/a hp"
Leaving the engine internals stock and just doing bolt-ons so its easy to smog, 10-15hp most likely.
Rebuilding the engine for the purpose of high HP, your budget it the limit pretty much.

Thats just the turbo. To get the most out of it you will want an upgraded mani/dp, if not need. Then you will need new fuel control because the stock it totally inadequate to handle the power you can make. The turbo will hold more boost more than your engine will! So, go shopping. I don't doubt that setup would cost in the neighborhood of 2K+.
Had to jump in here. Basic Bolt ons net pretty good gains. I have the following done to mine and plan on a couple more things in the future
Doug thorley Headers
2.5" Header back with test pipe
3" CAI
14' Timing
FAL Fans
PCV Rerout to Catchcan
EGR disabled
Electronic Ground Stabilizer
10mm NGK Wires
I figure an Underdrive Pulley and thermostat mod will just about do it for me(until that clutch needs replacing then its aluminum driveshaft and lightweight flywheel). Just set realistic expectations. If I dyno 200-205 at the wheels I will be more than happy.

Whats the 14* timing all about? And the Electronic Ground Stabilizer?
I dont have EGR on mine (UK spec), dunno about PCV and whatnot...

n/a internal will hold the same as the turbo internals, any of the na-t that have done it right have made power well into the 400's with just a mhg on the engine and supreme tuning.Noneed in opening up the engine unless u really have to, i know im not when it gets time for me to go na-t
Don't listen to all this, "go turbo" kookes. My NA is bone stock and pulls like a mother, once it hits 4000. If you are that hell bent on neck breaking power, quit posting here and buy a GTO. They're nice cars, LS2 and the rear comes out, beautifully. How does that sound?MKIII N00b said:
I bought my NA Supra, because it's a beautiful car and I really believe in it. I know it's going to cost a bundle to mod, but I think it's worth it. Is it worth it to you?
deng tough question. if i have the money then yeah. but im just stuck damnit this is a pointless thread, i might as well go turbo because ive been thinking of staying NA or going boosted, for all the money and what not i guess im going turbo. but thats when i get the money =]]] maybe 3 years?

It will be easier to swap the engine to a turbo or do a bolt on turbo to get power but you can make power with an N/a it will just cost you more. If you haven't seen Defiant7M's thread take a look at an (expensive) possibility. Going Na-t isn't too hard, I would however pull apart the block and make sure everything is good before you start, easier to do it all at once then to do it twice.

I am not really sure about the GE holding the same amount of power as the GTE...I would guess so, but since the GE has a higher compression ratio, there would be little to no room for errors when it comes to tuning...
^^Also it would mean more power with less boost. I'm certain the Na-t makes more power and torque than the stock Turbo.

my old '90 n/a made 227hp.
the mods were:
port and polished the head and intake manifold
ngk plugs
msd 8mm plug wires
cold air intake
pacesetter header
hks catback exhaust
gutted cat
i think that's all of it...sold the car four years ago.

ohhh my...... 
interesting discussion guys!
GT30R Is T3 flanged so you'll need an adaptor to use it with a stock manifold (you'd need this anyway as it has the Big Compressor cover)
The difference going Turbo is the amount of headroom you gain, with a modded NA when you're done you're done there's no-where left to go, with a Turbo you can always dial some more boost in if you've laid the ground work.
Something like the GT30 mentioned at 5>10 psi on an NA short block with a good head gasket is going to romp away from all but the most heavily modded NA 7M.
There's NOTHING wrong with tweaking your NA to get the best from it as long as you realise it's a bit of a dead end due to limited AM support, I'd suggest at the bare minimum getting it running correctly first as the basics are so often overlooked with the 7M ending in disaster.
