Wow angry posts sweet..... everyones taking it personal very objective
Hey Snoop
My advice would be consider it a bang for buck comparison like i think you are already, assuming you can get either cut at your stated prices, a Rb20det would poo on a RB25det with teh spare $1500 dropped on the baby 2L. Its simple bang for buck
Now looking at the previous posts

"But hell.....SR20s Have made me piss so i personally would concentrate on working with your engine to make it stronger instead of putting in a half bodged one from another car!"
Too true that dirty lil 4 potter in a light car wrecks hell with equal mods

"Rb20's don't make the same power for exactly the same mods. The benifit is they come in smaller/lighter cars factory and arent' a slouch of a motor."
You remarked how quick lag wags r31 silly is in another post 13.01.... its weighs in at 1390kg... much like a r33, Its a R32 RB20det a 3" a truck cooler and a high flow t3..... 290rwhp
"The bottom end is just as strong/weak on both the Rb25 and rb20. they are both very small engines and will rev like hell."
This isnt so, have you ever put a 20 rod next to a 25 one?
Also it seems the high compression ratio combined with weak pistons crack RB25det ring lands when they start breaking 300rwhp no?
"Both are good engines, same design, more cubes - more power"
Too True!!!!
When all things are equal
Dont waste your time rebuilding 25s then donate the head to a 3L

Completely stock making 252rwhp is extremely impressive never seen a stocker put down that power more like 170-180rwhp, cant see how its breathing through such a small exhaust
"Gradenko"
"Works Auto, I find it cute that a small group of anti-RB25 biggots have popped up in order defend the already well respected RB20 whenever its ability is questioned, but honestly, we're all on the same team here. Go Nissan!"
Paranoid...... lol but yeah too many emotional incites cant really go wrong with most nissan gear
"ndr"
snOOp,,,,With mild mods as you have stated the RB25 would be a better motor,,,,but if you want more power later on the RB20 gotta be a better base to start with,,,,lower Compression means a better Turboed Motor."
True reliable stock internals that can rev...... just add boost
If Ive annoyed anyone its not my intention these are my opinions
