On a mitsubishi eclipse GST, how much can you boost without doing any rebuilding...

you want a gsx not a gst... and LOTS.. you just need to update the fuel delivery to compensate for the added air.

I've heard of people buying them new tearing off the turbo putting on a t20 and running 12's at the track (that was a gst too not the gsx (awd))

My buddies 91 eagle talon was the most impressive car I've EVER been in. including nsx porsche rx7 turbo ii 300zx etc...
