So I'm probably going to buy an after market intake, and then I'm also looking for quick performance upgrades for now (not the +5hp sticker lol).

Any ideas?

 

What do you mean by "quick"? You could do exhaust, cams, valve train, nitrous oxide, N2O will give you the most HP for the $, turbo kit, or some kind of ecu upgrade. Unfortunately the ecu can not be chipped so you would have to buy a piggyback ecu or a standalone ecu. A piggyback ecu would be best if doing just intake and exhaust upgrades it will also show real hp numbers on a dyno. Without the piggyback you might not see any change. The exhaust is very hard to find and is pretty expensive. Just a few things I could think of.

I found that. Any opinions?

 

I wouldn't get something like that. Exahust/intake/header/nitrous will be your fastest increases and cheapest.

More expensive options are turbo charging, LSD, cams pretty much

 

With older cars like ours the best "Quick Performance Boost" is usually making sure all of the maintenance is up to date. Good set of plugs and wires along with a new dizzy cap and rotor. Also look into switching to synthetic fluids. I am running Royal Purple in my engine and diff. After all of that my car felt a million times better!! Beyond that for "Quick Performance Boost" some inexpensive things you can do are advancing you timing a few degrees over stock which is free. I installed a MSN blaster coil which was about $50. K&N drop in filter with better intake pipe. All of those things add up to a few more HP. Check out my build thread and you can see off the stuff I mentioned.

 

Quick performance boosters, or quick powerful performance boosters. The suggestions so far are good. Just depends on your budget, and how fast you want to go.

If you are so inclined, I have a complete 2jzge turbo kit I pulled off a 1994 GS300 I just bought, for sale in the classifieds.

I had nitrous on my last GS, and it was fun, but filling that bottle all the time gets expensive in a hurry. ..a turbo is always on tap.
