The heavy duty clutch i was running started to give up so i bought a hhdb exedy clutch and picked up a blown rb25 box so have a play with while it was apart, seem too all fit in pretty well so ill look at rebuilding the box and replacing the 20 box in the future
yeah, with the kind of numbers you are running you will likely need the bigger box... particularly with an aggressive clutch, but then again will also depend on the size tyres you are using and how aggressively you shift gears etc...
Does the bellhousing really clear?
In my car the bell is really the limiting factor by a long way, if I wanted to go to an rb25 box there would be a lot of cutting involved

put my new clutch in doesn't feel the best with a very high release point but im told these clutches can do weird things for the first 1000kms while they bed in so ill see how it goes
also had another couple of rockers break on me
had some hand brake issues so decided to strip the rear callipers down and do a quick clean and rebuild
and also found that the crank breather between the bottom end and the rocker cover is suppose to have a restricter in it so i pulled it out of the original pipe and put it in the new one
Went to order harder rear springs and this happened
Gone solid lifters now
Procam 260 solid profile (slightly smaller than the bc264s i had)
And a bigger map sensor
With some good results
wow i just read this from start to finish... good build man. has given me a few tricks for my build am going similar route (sr20det) very impressive mate.
For anyone interested this car is for sale,

Did you ever end up fitting the 25 box?
Just interested to know how much further back the shifter would be compared to a SR bell on a 20 box...
