Hey guys.
I just got myself a RB25 turbo for my RB20 and i was wondering if i were to put the RB25 turbo manifold onto the RB20 would there be any benefits or is it the same size as the RB20 one?
Also is the RB25 exhaust manifold bigger than the RB20s if so are they interchangeable?
Thanks
Andrew.
what about a rear wheel drive RB26 Vs the GTST.
Does that just mean if you made the RB25 into a RB28 it would just kick its ass? or still would the 26 be better?
Get a turbo before cams and you have to ask yourself if you dont mind lag or not, so buy a turbo around that, 2530 is good for 230kw with not much lag or you can go something bigger and get more power if you dont mind the lag.
just get a retune using the stock ecu (RB20 ecu to RB25) and put boost on 12 PSI.
and like boostin_r33 said dont get a 10 year old fuel pump get a bosch or walbro new.
a better LSD helps also , my mate went from normal LSD to a 2 way and now he cant spin the wheels so easy as now he has to get both wheels spinning rather than 1
