What should I Buy???

Hey whats up guys I just wanted to let you guys know that the engine swap went great. The newer lower mileage engine worked out good so far. Well let me tell you guys what I put in while it was out...

I put in a goodyear gator back timing belt.
Changed the A/C belt And the P/S belt.
Changed the oil pan gasket and put in a valve cover gasket kit.
Put in some NGK Iridium plugs
Changed the plug wires
Put in a Fram X2 filter
Mobil 1 synthetic oil
I also ordered some OBX cam gears that Have not arrived yet.

I know i didnt have to change all that but I figured what the heck while its out might as well take care of it all in one shot.

I would also like to know what else should I get for performance....?

I was thinking about an OBX header which will run me about 180 shipped
OBX Hi-flow cat about 65 shipped
OBX Cat Back system about 300 shipped
And an AEM CAI about 170 shipped

Are there any other minor mods I can do? I have about an extra 500 to spend I do have the 420a engine I know its not the 4g63 by a long shot but I have to make due with what I have. Or do you guys think I should just put a set of wheels on the car with the left over?

A buddy of mine wants to sell me some gunmetal 18's with tires for 500 they are in great shape. But I dont think I want to go with rims that are that big. I want to make the car faster not take away from it. Tell me what you guys think It will be greatly appreciated... Thanks

Somebody help this guy :( .. i just felt pity that this guys post was going down the list unanswered.. although i dunno wat to advice him.. i just helped him by bring back his post to the top :D

Homedepot CAI
OBX headers
OBX exhaust
Keep the stock cat :) Never thought i would be saying that.

I think that AEM is a waste of money. You'll be paying an extra hundred bucks for the name and still get the performance of any other intake. I would get the k&n intake.
