S13gts-t

Hello all. Been around rb20’s for a while. Mostly swapped into s13’s right now I own a 92 gts-t.

Doing more research. Maybe my idle is fine? This Rb is in my s23 with stock gauges. Would read higher due to having 2 more cylinders?

Appreciate the replies. I’ll put it back together this weekend and try it

Please help me friends. At my with end. Have torn this engine down and rebuilt with all new seals and had cylinder head machined. I finally have the engine firing on all cylinders. Sounds smooth as butter. Only problem is. My idle won’t go below 1800. here is what I have tried. adjust idle screw all the way in(closed). Blocked off cold start valve(1600 rpm), Adjusted cas. Pinched each hose leading to the intake manifold to see if there is a change in idle(no changes). Cannot hear any vacuum leaks. known problems are that the manifold gasket that is between the upper and lower parts of the manifold has a tear in it(not very big, definitely not enough to idle at 1800rpm). No o2 sensor connected right now(don’t think it would change idle a lot, maybe I’m wrong?)
