I bought a JDM from them a few days ago, they delivered it to the mechanic and gave a 3 month warranty.. The mechanic just put it in. Turns out the turbo doesn't spool that great, I drove it myself, and it drives like sh!t. The compression on each cylinder is really high, which is good, but the turbo is crap. It lags a lot and doesn't boost past 0.5 on the gauge.

I'm really pissed cause I just spent $1500 on the engine + labour... Anyone ever deal with these guys? I want them to take out the turbo and put in another one that works correctly at their cost. I think thats only fair.

But I don't think it'll turn out that way. Anyone have suggestions on how to deal with these guys?

Thanks.
