Soooo, I just bought this 1990 S13 off a guy who paid someone to do a very half ass RB20 swap and I have been finding nothing but issues with it and am almost at the point of being brain dead running around in circles searching one issue after another. To start with, and to give you a hint on how much of a dummy the previous owner was, the intercooler piping was on backwards... (believe me I'll be posting pictures soon) so that was basically the first thing that got swapped. I wouldn't have bought the car if it wasn't a steal and I didn't wanna see a perfectly good S-Chassis go to waste. Now for the issues I can't seem to figure out.... I checked my plugs last night and cylinder one seems to be flooding? pulled the plug and it was the only one that was wet so I have no idea whats going on there, and then earlier today I started it up and it would hardly hold an idle, then when trying to drive it was like I had a Bee-R installed and it was hitting the rev limiter at about 3000 RPM (which I can't really tell if it's 3000rpm because the RPM guage doesn't work)

I Love these cars and love it even more with an RB because I have always been a fan I know they are a ton of work and very very picky but if anyone has any ideas or needs more info from me to help me figure this out please PLEASE HELP! Im beyond frustrated with this thing... any ideas would help.
