ok listen, i have done 3 rb25det swaps into s14's and i have to say that that motor SUCKS BIG DONKY BALLS. What a lump, and as for tring to get parts when something breaks, ha, impossible they never run right even stock. and a rb25 will never make 800hp, you'd be lucky to get a relaible 400 to the wheels. just save yourself a bunch of headache just because you feel you have to be different to be cool and just go and get an sr, hell if you wan tto be different and make power go get a s15 sr, it makes more power stock then any rb25 and it hauls ass. so seriously, rb's are the SUCK. They are ok when their in a Skyline but in anyhting else the blow.
