The Forced Performance FP3065 should let me attain 650 horsepower.
A polished stainless steel tubular header exhaust manifold is mounted on it. I also have a 40 mm TiAL external wastegate with dumptube.
The 3" O2 housing/downpipe has v-band clamps. I recently polished the aluminum compressor housing since it was originally just unpolished cast aluminum. It has a 2.5" 90 degree elbow welded on for a stock-like fit with 2nd generation DSM intercooler pipes.
The stock Mitsubishi T-25 came setup for 210 HP at the factory and could only afford ~300HP when the boost was cranked up. It also had a very small internal wastegate with weak flapper.
