Our HX52 holset isn't much smaller goes good with no spool valve

the main reason for the spool valve is drift track work and a whole heap of because I can with a dash of I wonder if it will work. the holset would be a better turbo than a china any day that's for sure.

that's how people learn what works and what doesn't and that's how technology progresses!

Great looking conversion, keen to see how it goes! Fair few early 6cyl falcons with boost making some good numbers.

I cant see any real reason why it wont make some good numbers if the deadly ping stays away.

hey guys can someone explain to me the idea behind the spool valve & how it works? very interested to know, cheers
