Bang For Your Buck
Ok...so there's a lot of information floating around this forum about good performance upgrades but I want to know what the following:
"What would your list of specific (brands/websites) bang:buck performance parts be if you were on a budget of $200/mo and what order would you do these in?"

here's a list of what I would do (and have 90% of it done):
1: 2.5" straight exhaust with a straight through muffler (unless you're turbo, then go to 3")
2: Header, I know people say it doesn't give you any gains, but it makes the car sound badass which makes it feel faster lol (only for NA, again, the factory turbo manifold flows MORE than enough)
3: Cressida or 280ZX Turbo AFM swap (only works if you're NA though)
4: 240SX/KA24 Throttle Body swap along with the mouth of the intake manifold ported out.
5: Megasquirt it
6: bigger cam
7: headwork
8: high compression pistons
9: ITB's or triple Webers
10: stroker motor
11: bored out stroker motor
of course, that's only engine wise performance, I've learned that these cars are fast enough with a mostly stock motor and that you should focus on the suspension/braking portion of the car first
Stainless Steel Brake hoses should be pretty high on your list. followed by polyurethane bushings, and then new shocks/struts, and high performance springs and larger sway bars

Thanks, PontiacKid. That gives me a few cheap upgrades I can do in my yard. 
As for the rest, I should be more specific. I'm limited to about $1-200/mo but want to improve the over-all performance of my car. Everything from handling to acceleration.
How much gain is there from doing the AFM swap & which of the 2 would you suggest?
Also, what brand of headers would you use?
As far as engine work goes, I won't be able to do any rebuilding any time soon. So tearing the engine down is a no go. Is there a way to do ITB's without a custom ECU to control then? Also, when you're talking about the KA24 throttle body swap, are you talking about the part that bolts on to the stalks? Is a specific adapter plate required?
Skib, I have the stock L28

I can vouch for top end improvement on that one!

Is a specific adapter plate required? they sell them (palnet) but you can just as easily port it out/port the manifold.

on the KA 60mm TB swap;
its not really "performance" upgrade, it will provide somewhat quicker throttle response.
if you run it, port your manifold out to 60mm. because even though your TB is 60mm it will still be going into a 50mm hole, defeats the purpose of putting a 60mm TB on no?
I dont recall if the butterfly hits without the spacer or not
the 1in spacer; you will need this if you want to run the stock throttle linkage and you will have to custom do the linkage on the TB itself (search hybridz for a write up)
if you want to really increase performance at the intake, gasket match the runners, the small runner diameter is the choke in the stock intake

That's pretty much what I'm doing. Here's a rough list so far...
79 280zx -205$
complete aluminum v8 -110$
forged pistons for v8 - 67$
transmission - 220$
Half shafts for yet unaquired differential 20$
turbo 130$
Headbolts 10$
alternator and starter - 40$
electric cooling fan, afm, various sensors and wiring 50$
Flywheel 50$
about 900$ so far, and been driving it for 3 yrs.
Things I didn't count, title transfer fee, license, tps switch for l28, heater core and alternator that blew, and new(used-perfect) dash speedo and guages. I figure this is maintenance cost, not modification cost.

the things that are going to open up power on the L28 N/A are head work, cam, exhaust, ported/custom intake, and when you want to get into really tearing things apart, some higher comp pistons, going 3.1 stroker, ect.
note on getting a burly cam tho: if your running efi you should be using an aftermarket ecu so you can adjust the AFR since its going to be wanting to eat up more than stock . or run carbs
triples would be badass
but just for some cheap stuff you can do for now. for starters, toss on a header with 2.5 in exhaust. I recommend a resonator and muffler, its loud. I had a header with 2.5in pipe and just a muffler and you couldn't talk in my car
second, gasket match your intake runners if you have the skill/tools. having a good tune and quality ignition parts helps too, not in hp but making it more efficient

many of those upgrades I wouldn't call a good bang for your buck. Its like $200 each for an additional 3-4hp each.
Save for 2-3 months. Buy a $500-600 turbo 280ZX parts car.
That's a good 50hp and 60 foot pounds of torque right there. Its all up hill from that point.
If you want to build a non-turbo engine, then buy an engine and build it on a stand while you drive your car. It'll take you 2-3 years with only $200 per month to build it up to 200whp.

Thanks for the input, guys. I'm liking some of the ideas I'm getting, especially some of the stuff I didn't know was possible (like swapping the Cressida's AFM in). I'm also starting to think that doing an RB swap wouldn't really be necessary for the kind of power I'm looking to make (I'd say max 220hp).
Skibs, what did you mean by gasket matching the runners? When it comes to terminology, I'm a lightweight but I catch on fast.
The KA throttlebody & webers sound appealing to me, as I like a car that responds more than I like going fast. Is there a thread or HowTo somewhere for the Weber conversion? Is there a kit for this or is it all custom work? I don't have access to a crazy amount of tools, but could do my own light porting/drilling/etc.
Not really keen on going Turbo, I have a tendency to lean towards cars with NA engines. As far as my $200/mo goes, this limit will slowly go up as I pay more & more of my debts off.

the webbers are just triple carbs, take off your intake and all your EFI stuff and bolt on the intake and carbs.
if you pull the intake off and set an intake gasket on it you notice the runners smaller than the gasket holes, you use it as a guid to how much material to take out. just google it

the TB swap is much cheaper, but your just swapping out the TB, with the webbers your ditching your EFI and swapping in a whole new intake and fuel induction

lol you cant compare the two, there totally different things
Id suggest doing some reading on how and why the parts of your motor work
and the specifics of those parts on the L28 before you start modding stuff.

First of all, I can compare apple trees to road apples if I want to, i'm not stuck on the l28, or anything else for that matter, we're talking bang/buck, no holds barred...
