well if your looking at a swap your going to be getting a jdm engine.. you can just forget about usdm. and if your getting a jdm engine and your obd2 and dont want vvt-i then you can forget a swap. now the real difference between going NA-T or just swapping in a 2jzgtte is the rods and the intake manifold and compression ratio. the NA engine has weaker rods and much higer compression so untill you lower the compression your stuck around 8psi on pump gas.
If I remember correctly, the Newer 2JZ-GE engines have the problem with the rods (~2000 and up I think)...
DaveH ran a 9.78 1/4 mile on his NA-T MKIV w/ a TH400 tranny.
Of course the awful non turbo intake manifold and its not so easy to just swap in the tt manifold either youve got to worry about throttle body position along with other things getting in the way.
Again, DaveH makes a TT style intake manifold for around 700 bucks.
if your planning on really making a high hp monster i would go with the swap cuz in the long run it will be less expensive to acheive 800 900 or even 1000 hp if you really want to go that far.
Might wanna let ethan banks know that -- he built a 1000 HP SC... Built NA-T
there are many nice NA-T kits tho i just got my turbonetics fmaxx kit on and i love it cost me 4000 for the kit and the install will be slightly cheaper than swapping in a new engine. the price actually comes out to being decently close for both of them. but going NA-T depending on the kit you get you should end up with a little more hp than a stock tt
I'd take boost logic kit (www.boostlogic.com) for ~$3999 that has a tubular manifold made out of 341 SS.
A BPU TT will put out 450 RWHP on average, it will also run the 1/4 in about 12 seconds.
NA-T can be cheaper if you're smart about the parts you buy, but finding a deal on a donor MKIV 6spd TT will win out... your stock tranny will go after 450 (the 5speed W58 is a time bomb) and the open differential just has to go...
Either plan on 300-350 HP for 5k, or look for a wrecked TT that you can pick apart, because the driveline isn't going to hold up well at all.
...or combine the two and plan on NA-T w/ a thicker head gasket in a built tranny (if you're an auto) or a 6 speed donor if you've got a 5 speed.

Either way, it's not cheap.
