Well, with my setup right now, i'm looking at easily 450 and thats with stock injectors. So you should be able to make 450 no problem. I know guys who own gtr's with stock 26's that are running 420 with stock turbos. That motor is seriously underated and sometimes guys give it a bad rap, i dont know why cause it can make serious power with little mods. It sounds like your heading in the right direction though, my only advice is to not cheap out and hack stuff together, unfortunately this motor deserves attention and respect, if you do it properly it will repay you in power.
Yeah I had a 200zr pan which is what you need to just use the stock Z mounts, but then I discovered the block on an AWD have a different location for the pickup. So I sold the pan and bought a regular RB25 pan and had this guy reverse it into a rear sump steel pan. So if the measurements are right I should be able to still use the Z mounts. If not then I will either use Q45 mounts which are bigger or I heard mounts off of a mustang will work as well. So we will see as soon as I get the pan back. All I want is about 450 Hp and I will be happy and leave it at that.
So Sniper how far have you gotten into your swap. I am doing the same swap myself right now. I should be test fitting everything in the next week or so. So far I have everything except the FMIC, Nistune, and flywheel. I got a guy in GA making me a upgrade pan with a rear sump. I was told mounts. Oh well hit me up if you still doing it or have any info.
you should do a how 2 that would be nice... make a list of all the things you got and take a pic of the bottom and the suports, cuz i want to do the same RB, is lighter then VGs
