right then guys !! spool up and top end power, is there really any difference between these 2 turbo,s ??

i have a vf 34 currently on my rb5 but bearings are wineing a bit so have now had delivered a vf28 ( now when i oredered it i was told it was a vf 34 but as it happens i have found out that the inner core fitted is brand new and that of a vf34 !!! so outer casing vf28 and inner core vf34 !!! turbo developements have said that when you order a new vf28 from ihi they send you a vf34 as its replacement as they are the same !!! just had bob rawle map for my vf34 so will fitting this tomorrow mean another tweak ??? any idea,s would be appreciated !!

youll top out at around 330 bhp on the 28, not a bad stock turbo though

The vf28 is nothing like a vf34 matey,going from a 34 to a 28 deffo requires a remap and you will notice a world of difference between the two tubbys.the 28 will have shot its pot full before the 34 even begins to come on song,hence the huge price difference.the 34 is one of if not the most sort after of all the vf range,fantastic turbo and performs awesome on any model imprezza..GOOD LUCK.

cheers for the info guys but why do people go for the*vf34 ?? turbo dynamics said that they are the same turbo !! same size houseing and both roller bearing turbo,s !! i mean my vf34 only came off my rb5 as the bearings are wineing !! was making good boost when mapping with bob !!

some people say the difference is night and day between the 2 turbo,s but not much power difference between them !!!
