Tidgy Posted February 8, 2017 Share Posted February 8, 2017 depends how far you wanna go, top mount will be at its limit if you do much more so your looking at front mount, then maf becomes an issue so wanna look at going aftermarket ecu (syvecs is by far the best but not cheap), then you have injectors, fuel pump etc etc SC36 or SC38 will be a good step up, or an sc42 if you wanna break the 400 mark, bearing in mind above.
