I'm running a 22RE. LC engineering head and header.

I traded tire with a friend of mine yesterday. I'm now running 33's. No improvement in power, or mpg. I was blown away by how much better it handled though. Its much much more stable and quicker in the turns. The steering is also more reponsive. The physics of it makes sense I just was not expecting that much of a change.

 

Regear and lock it. Try a lockright, I tried Jay351's the other day. Doa quick search.

 

Now I'm looking at the really randomn. I found a Mercerdes 300TB for $1000. The car runs great, but is beat to hell. 123HP and 181ft*lbf seems like good numbers and it looks like it should fit. I'm just not sure about adapting everything.
