wiki says that the rb26 runs at 14.5psi stock but has a enternal boost limiter in the actual motor so its more like 10psi take it with a grain of salt ill test it out once i get it running with a boost gauge, i would def think about some fuel injectors, rb20s only are 270cc and with a stock rb20 turbo being a t25 and stock rb26's are t28 so double the size and pressure of stock......to close to call but id rather have acouple more bills into it then having to rebuild and having acouple G's. found this thread on nico kinda discouraging but i still want to see what i can get. http://forums.nicoclub.com/zerothread?id=413133 also in that fourm the dude turns up boost to 15 psi and blows the exhaust turbine right out of the exhaust ie detination

hey man, was at work looking at rb20dett on google and thought i could give you some help. some things to know, don't know what frame your putting it in but putting it into a s13 the stearing column is in the way (left side drive) you need a custom downpipe or mckinney's. with mckinneys rb26 pipe they shave the pipe so it will fit but with the rb20 it sits farther back so you will need to shave the pipe about a inch and a half more towards the turbo. also where the downpipe and muffler connect the downpipe pushes against the bottom of the car would suggest some sort of spacers. you got the manifolds down all i did was chopped and rewelded the flanges in the proper place you only have to change two flanges the intake: relocate the bov. Take a fmic w/pipe for a rb20det(r32) and some universal pipe and custom fit it, would be so much easyer with a aftermarket intake mani(had to cut my hood to make it fit with a stock mani...) I suggest blow thru maf if you can remap or tune with a piggy or standalone (which you need to tune if its blow thru i wouldn't risk running stock mapping as you can lean out the engine) then just put a air filter on each turbo and your done. If you want a draw thru you will need to make a pipe to go from each turbo to the maf obviouslly....not fun next thing is the turbo oil/water lines, get stainless steel lines custom made, also for the turbo oil return you will need a brass T fitting i believe mine was 7/8" (way hard to find) connect with some heat/oil freindly hose. unfortunatlly i started it up and found out that i got taken on the motor and had blown rings so i don't have any idea how the set up runs....haha lame i know but it should pull, the rb26dett stock boost is at 14 psi. im concerned about leaning so i would suggest a aftermarket fuel pump and nismo FPR. i would deff make sure its not running lean before you get on it. totally hope this helps, ask any Q's if you got any. also every swap is different so you might run into these thing or you might not... haha my bad if there is any grammer issuse its like 3:53am workin that graveyard
