RB series Dimensions?

[cruisey]

I'm not sure if anyone can help me or not, but I'm trying to get the external dimensions of an RB20DET. My friend is modifying his *shudder* 1990 Nissan Pickup, its slammed and all that minitrucking jazz, but it really needs more poke, and he is a Nissan junkie.
We need to measure to see if the actual engine will fit before he lays out his hard earned cash for it.
Can anyone help with the length/ width/ hieght statistics, or know where I could get them without phsyically going to a wreckers? Currently we're too busy to do it ourselves (sad I know). Hopefully he can save up some more and get the RB25DET for some real tyrefrying fun.
The bonnet is very narrow length ways, so that might cause a problem. A VG series might also be out of the question because of his raised front guards (this thing is looowww) so that might not fit width-ways. Thanks for any help. It is geatly appreciated!
