Phillip1993 Posted July 31, 2016 Share Posted July 31, 2016 I'm probably going to be heading towards the 350bph limit on my impreza's gearbox and i'm wondering what would be a good replacement that's not the far to costly 6 speed sti gearbox Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 31, 2016 Share Posted July 31, 2016 Bug onwards 5 speed boxes have stronger casings and tend to handle high 300's maybe just over 400bhp (if treated with mechanical sympathy ) You'd have to Google your existing 5 speed box ty number (to find the ratio) and buy a later 5 speed of the same ratio. You'd just need the box (about £400) as shafts, props , fly ,clutch ect are all compatible with the classic set up 😉 If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...

savage bulldogs Posted July 31, 2016 Share Posted July 31, 2016 It's still only a ty 52 (weaker early classic box) You'd need a ty54 late v5/v6 classic at least , preferably bugeye onwards 😉 If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
