Best mod you have done to your rex to make it run better?
What's the best modification or new part you have put on your rex to make it run better or drive better? I'm just wondering what I should do first this summer since my rex has sat for some time and needs a lot of new things. I'm thinking suspension first.

First get it in tip top mechanical condition. Replace all rubber, change all fluids, get all the eletrical sorted (lights etc) and make sure your brakes are in like new condition.
From there this is the order:
1. Replace entire stock exhaust with headers and proven exhaust setup.
2. Remove rats nest
3. Make it breathe; a reworked nikki (aka Sterling) or a large two barrel (too many to list) or RB holley setup
4. Upgrade fuel pump and put it on a relay
5. Convert to an electric fan setup
6. Go poly on most of the suspension bushings.
7. Better springs and shocks.

2nd gen direct leading ignition. 5 mins of wire splicing after buying a $20 coil pack off the used market, and you've got a smoother idle and a more powerful spark. I actually saw gains when I did this that I did not expect. I even had a friend ride with me who knew nothing of the mod, tell me my car seemed faster (non-promt with a question like "Does the car feel different to you" I might add).

.I've been planning on getting a tune up soon and having the carb worked on. I will also look into the steering rack. Thanks.

Poly bushings in all the suspension links was one of the best mods I did. It improved the ride, road noise and made the car more responsive. Braided stainless steel brake lines is also at the top of the list because they made the pedal firmer and much more confidence inspiring than the stock rubber lines. $100 for a great upgrade.

I'm also going to be doing a lot of cleaning of the engine and working on the body to eliminate some cancer. I also gotta replace some parts that have just gone bad after sitting for so long, and just find out where some random wires/cables go and come from.

Well the clutch made it go from 'not running at all' to 'running quite well' so I guess that was the biggest :P
Aside from that, the shocks and springs made a huge difference. No more slamming the bumpstops crawling over speedbumps.
