I OWN A 1994 WRX IMPORT, AND I CONCIDERING WHATS BEST TO FIT TO MY CAR. I LIKE THE SOUND OF AN EXTERNAL WASTEGATE, BUT I HAVE HURD ITS BETTER TO FIT A BOV. HAS ANYONE GOT ANY IDEAS ON WHAT IS BEST. THE CAR IS RUNNING AROUND 300BHP WITH A FEW MODS EG MANAGEMENT TD06 20G, FMIC.

ANY HELP WOULD BE APPRECIATED

 

You cannot run an external wastegate with an TD06 turbo or any other turbo with an internal wastegate. Well you can but it would be a lot of trouble for no benefit.

If you want the noise then get a VTA BOV.....however, the best dump valve you can get for your car was what it left the factory with.

 

I am actually trying to decide if i should upgrade my Turbo the a GT30 or to convert my TD06 20G to run an external wastegate.

The external wastegate sound is so much nicer than any BOV i have ever heard.

You would need to have the penny valve welded shut. (Simple method) or like i am considering, strip the turbo down, and a blank machined to fit where the penny valve use to be, and have this fitted and welded in.

On my business partners car we run a GT30 with a Tial wastegate, we had custom pipework made up to sit the wastegate up at the top beside the turbo rather than hide it away... looks lush. and fitted a screemer pipe. the pipework to fit the wastegate cost around £200 but the Tial wastegates are around £350

so if you are handy at removing your own turbo you could be looking at around £550 - £600 to complete.

but you can get cheap wastegates on ebay for £70

However a top quality BOV for around £150 would save you some pennies for other Mods.
