I have never taken this thing to a dyno or to the track. I've never raced anyone in it either. Just drove it fast on the streets but never abused it. It never made the knocking rattling before the dyno pull. Plus the car was vibrating very hard during the end of the pull. So something may have been shaken up inside. I don't know.

Again I'm not blaming anyone. Or any shop. Its just one of those things that happen.

So here's the uprgrade:
2.5L STi Short block
Stock WRX 2.0L Head
VF34 Turbo
Catless Uppipe and Downpipe
TBE Catless 3.5"
STi Pink injectors
Looking for an STi Topmount (or aftermarket TMIC)
Walbro Fuel pump
Cosworth Light weight Forged Pistons
And leaning toward Ecutek Reflash (open to suggestions on this)
So far thats whats happening.

Then a Dyno pull...J/K .
