Out of pure interest and getting solid confirmation on the block in the S401. if/when you get a moment see if you can identify a S20C code, in between the PS pump and alternator
Increasing the redline to 8000 would be easy if I had S401 definitions.. I dont currently but i'm sure they are blowing around out there somewhere. You could not have it gear dependant though, just a global increase.
Also at the end of the day its your car so if you want to ST a S401 I'll support you haha
This right here is a good opportunity for someone
@Individualities I’ll be selling my whole set up in a month or two. Process west tmic, vf34, SSI headers and 3inch down pipe in a few months if you want them! Everything will be there to convert yours to single and make 225WKW. Even the silicone turbo inlet and a shroud I custom made to fit the intercooler on a BE5 (:
