If your WRX is anything other than bone stock, but you don't feel like taking up space in you signature for your mods list, put them here or in your profile. This stuck thread will serve as a reference for all members to see what mods each WRX owner has on their car. Start with a description of your WRX as you bought it. Feel free to include installation or review links and/or 1/4 mile times with your mods list. I'll get us started.

My mods.

What turbocharger are you running on your Axis engine? Stock boost implies that you're still running the stock TD04.
 
#307 ·
.....

yea.... stock ECU, turbo, & fuel! Sucks, but I have to crawl before I can walk. Axis charged about $2199 for the block w/ internals, but there's supporting parts that you have to get w/ it... gasket sets, head studs, head gasket sets... blah...blah Plus I'm paying like $2500 getting it installed.... so yea, I'll be working w/ that stock turbo 4 a while. :)
