RB20 fuel problem!??!

[lilskyline240]

my buddy has a rb20 swap in his 89 hatch and it worked perfect for 2 year. he put it away for last winter and hadnt taken it out till this weekend cuz he has been restoring the body. well now hes got a problem. Car starts up and idles alright but the second you give it gas, or any kinda load it just floods with fuel and dies. what do you guys think it is? MAF? o2 sensor? TPS not set correctly? im not really Good with RB's im more a ka-t man myself but i just want to get some imput from you guys before i head over there tomorrow and look at it

Yo, I had the same problem with my rb25. I replaced my o2 sensor with a universal 3wire for a 300zx and I installed a universal fuel pressure regulator and turned the pressure down, worked awesome. Got all the parts off ebay.
