Yoshka_81 Posted September 11, 2016 Share Posted September 11, 2016 I've had a good look online and havn't really found anything substantial so just asking does anyone know if you can modify the existing plenum or fabricate a new one? Would it make a difference in power? Quote Link to comment Share on other sites More sharing options...
mjrstar Posted September 11, 2016 Share Posted September 11, 2016 My 1ggte kp has a ff manifold, probably not a lot of gains to be made especially on an NA. It's the original runners welded to a new rolled and folded plenum. Power wise a camshaft upgrade will net more results than modding the plenum. Have you considered running ITB's?

Yoshka_81 Posted September 11, 2016 Author Share Posted September 11, 2016 Yea itbs are a very long term goal haha more just wanting to do it for aesthetics at the moment not fussed about power just didn't want it to lose a whole lot because of it. Have you got any pics of yours? Quote Link to comment Share on other sites More sharing options...

Ooh that reminds me, I found a photo of when the engine was first fitted, will attempt to scan for you. Quote Link to comment Share on other sites More sharing options...
