Okay so ive got an 86 turbo coupe 5 spd d/r turbo and i was wondering about blow off valves... Is it even worth while? i think it would just for the sound . Any preference in brand? Any info at all... thanks.

If you get one, it should be the recirculating type which are not very loud...if you get the the ones that blow off to atmosphere, your fuel management thinks that the air blown off is still in there and dumps too much fuel between shifts and could cause drivability to suffer, unless you buy some $fancy$ turbo management equipment

 

besides, with factory boost you dont really need one anyhoo, your throttle body has a way to vent the excess pressure for stock boost. you should do some other mods first, IMO...intake, exhaust, IC, etc

 

I do have a spare 1g dsm bov if interested...it may go on ebay, as I need the cash now

Awsome thanks for the info... how much do they usually run?

i paid $35 for mine. check ebay type in 1g bov

i need a bov for my rx, i have the intercooler for it, but didnt get the bov with it.

subyrally, what IC did you get? the bov I have is from a firts gen dsm (eclipse/laser/talon/galant vr4) and does not mount on the IC it is teamed with

i have a stock wrx ic, i just need to get the turbo and a few other little parts.
