96 SC300 NA Build
I found another thread about someone asking how much ho he/she could make off of just an NA engine. I quit reading halfway through because no one gave an answer. I'm simply here to ask what I COULD DO to my NA 2jz for the time being for fun/hp gain. I'm going to turbo it later down the line (R154/R167 tranny swap before turbo) but right now i'm just wondering if there's anything I could do to the base motor. Better camshafts? Lighter pulleys? Relocate intake/throttle body (FFIM)? Anything?

Then you'll be wasting most of your money, and accomplishing very little. The mods for NA are not cost effective for turbo, and do little in any case.
More camshaft will increase peak power, and (in general) reduce torque and street manners in proportion. A mild cam (I have an HKS 264 in my GTE) still costs well over $1,000 + new valve springs + install labor, and does very little NA (but may help with a turbo). A big cam produces more NA power, and worthless for anything but a very serious turbo.
Lighter pulleys lighten your wallet.
A full exhaust system ($1,000 and up, + install) will add perhaps 20-30 hp.
The ITB you may see in line are $$$$, require new electronics, and do very little.
The traditional older V8 stuff (bigger valves, more compression) are expensive, and do little - not to mention disassembling the entire engine.
Stronger lower end parts (new rods, better main caps, head studs) add no power at all, they're just for safety.
Nitrous will instantly make the car much faster (50-75 hp) - and break everything if you're not careful, about $1,000 + install, yes it can be used with the turbo also.
This is not a Chevrolet L6 producing .6 hp per inch of displacement (250" makes 150 hp), in such a crude state of development that any speed equipment helps immediately. The GE is only 183" and already makes 220 hp, already beyond the reach of most older L6 engines.
