Hello everyone, i'm new to all this, this being my 1st post so here goes...!
I am also looking into an engine conversion for my 240k, personally i'm inclined to get an RB20DET because this engine should suit my prefernces for the car.
1: it's still nissan
2: easily daily drivable
3: strong enough for hard driving
4: loads of potential for upgrades from aftermarket
5: easy for parts and service
i hadn't thought of too many of the downsides that are previously posted so i think i'l probably dedicate some more time to research on it.
My research found that for an RB25DET froncut with R33 Gbox is roughly about $1200 to $1500 more expensive than an R32 RB20DET frontcut. (in S.A)
because i'm new at this i wanted to get a frontcut because i'm not 100% sure if an engine package will supply everything i need. and its only $300 more for the whole front end over just the essentials(engine,coolers,computer etc).
also i found that here in S.A we can put an RB30 into a 240k with out an engineer checking it and without any necessary upgrades. just ring up and tell the motor rego office the new engine number and they send you a new rego sticker. With an RB20DET theres brake upgrades, full inhouse inspection of the car, potentially even chassis strengthening and more. with an RB25DET i think it would just be more so again! even bigger brakes, stronger chassis etc. but really i want the turbo option so i'l probably stick with the RB20 an see how i go.
Is there anyone who has succesfully fitted an RB20/25 to a 240K and has a description or information on how to fit one? any help would be greatly appreciated!!
