twin turbo conver to single
 

hey i have a 1986 GA70 twin turbo and I want to convert to a single turbo
what do I need to do can I just put a big ass tubo on or to I have to do mods?
Thanks

hey mate iv got a 3rd gen 1gg & i am just fitting a t3/t4 when it turns up.just have to make a simple y pipe.should be able to run same boost as before 11psi std & 14psi on high may have a bit of lag but lag is just a clutch kick away.you will just have to make sure you dont run lean.sugest dyno run after you fit turbo to find out how much boost to run without running lean.dont be scared.
