Why is my RB20 turbo chirping at idle. (Video Inside) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Dropped a RB20det into my s13 almost got it going except having a few issues. Revs and idles fine but will not drive for more than a couple seconds until it starts bucking and having little to no throttle response. Also have this annoying chirping sound coming from the turbo at idle.

Anybody got any ideas?

update: no longer chirping.. was due to the breather tube on the front right of the valve cover being blocked off. heres a copy paste on a diff theead:

update: ok opened up the breather that we originally had blocked off.. car now runs fine with people in, but after it heats up it begins to blow smoke and lag extremely bad. starting to think it's a blown head gasket. here's a video
