Anyone got any knowledge of IHI VF23 and what its characteristics are supposed to be?
Fitted to my STIV3 and have to say get great grunt low to mid.
Is it used anymore?

 

I have it in MY98UK-like. Running with standard ECU + Dawes up to 1bar kills performance until 3000rpm above 3500 comes to full power and holds it to redline. No major lag after gear change and it is capable to 330-350PS.
