I have an old h1c that I've had sitting around for a long time. The Assy. Number is 3528741. I haven't been able to find any info on it at all. I measured the compressor wheel and got 50mm inducer and 80mm exducer. It has a non wastegated 18.5cm on it that I know I'll replace if I use this thing. My main question is how much power can I get from this thing? I only paid around $50 for it so spending a little on it is an option.
