Firstly, screamin', sounds like an awesome N/A you got there.
I own a 93 r32 rb20de, stock accept for pod filter, KYB springs all round and various other non performance mods. Will be addingextractors to list very soon. My mate also owns a 93 r32, but its had an r33 rb25de engine dropped into it. Mods on his skyline is the pod filter and what he believes to be a nismo 2 1/4" exhaust. We go driving all the time and are always pushing each other to see who is quicker! When we pull up to lights we always have a bit of fun and have a bit of a drag. I would say 9/10 i will beat him. Even after he has a service, tune, etc. Now either he doesnt push his car very hard, hes not a very good driver, my rb20 has more guts than i think, or there is not too much diff between the 20 and 25?
Will have to get a dyno and see!
