Is there any sort of walk through for installing a blow off valve? I have recently been given a GSP Type RS and wanted to give it a try, however I've never installed one and would like to give it a shot

 

if you don't want to give us more information, then for starting you want to install a turbocharger on your sc300 or sc400... The blowoff valve installs on the hot pipe leaving the turbo charger.

now i'm gonna read your mind and take a wild *** guess that you have a first/second gen 1jz-gte with a MAP sensor, then just replace the old blowoff valve with this one and plug the diverter hole where it used to dump the air back into the intake.

Some people can be so lazy with their posts, more info and we can be more helpful. Pics of your set up would be even better
