Rb20det s13 runs perfect but slower than a civic Hey everybody, i just made this account because ive been browsing this site everytime i need to learn something about my engine(rb20det) and the info yall got here is incomparable to any forums in the US where its just a huge internet argument. With that being said i havent found anything on this forum that adresses the issues im having so here goes. I have a rb20det swap in my s13 running everything stock, its holding boost at 10psi, the wideband reads 11-12 on boost and around 15 at idle, the timing is set at 15* and everything appears to be running perfect except a little idle fluctuation from 680-780rpm and sometimes i need to hit the gas when cranking to start it. The major issue im having is my car is slower than my honda accord but seems to be running fine, i can feel the turbo spool and the boost comes on but its still very very slow. Any help would be greatly appreciated
