Not JDM's fault, I drove it too hard. So I put in a forged shortblock and I'm in the process of doing some suspension mods. It's a lot of fun. My advice is play it safe if your car is a daily driver or just a street car. But if you want something fun, she can be that too. You just need to have a solid plan for the car when you start. Just my 2 cents.

Oh, I can't wait to go back. Now she's got a torque arm, coilovers, T56, and lots more...
How much boost and rwhp was it making?
