Fitting a blow off dump valve

[David Clarke]

Im thinking of fitting an after market blow off valve to my car, is this a good idea and if so is there anything to look out for?

there are some carp ones out there and heard lots of fake copies of hks or forge ones.

leaks, sticking, or incorrect spring can case performance and general running issues.

any ideas on this 20g 16g 18g etc ive still no idea

The higher the number the bigger the compressor wheel so the laggier it will become unless other supporting mods/upgrades are done to utilise the possible extra power available

The compressor inducer is approx the inlet internal diameter  of the housing.

 

If you are replacing it because it's smoking, why not get it rebuilt?? (even possible  with MHI turbos to do it yourself if so inclined).

The 20g is also in the list posted

 

[scoobyjoff]

ok so a 20g would bolt straight on then would it 

[scoobyjoff]

so would this fit or does anyone know of another that will 

[The Don]

In theory.

An information page as AF no longer supplies turbos
