Redtop Or Silvertop

[poeticjustice88]

Is there any way to tell an rb20det from a redtop and silvertop. I know the inlet manifold s are different, but bot models had this manifold, so how else can I tell which engine this is?

All I need to do is find out which gasket kit to get for my inlet manifold, but it is looking to be a mission to find out

no ; both models had different intake manifolds

Redtops have "NICS" on the manifold, as distinct from "ECCS" on the pictured manifold. Redtops are generally from R30 / R31 Skylines, Silvertops are R32 (although that engine bay doesn't look very "R32").

Don't forget Z31 (with a top mount intercooler)

Don't you mean INTERWARMER?

The other difference in the manifolds is the redtop manifold has dual ports for each cylinder - because it runs a variable inlet runner design. Silvertops have a single inlet runner with a single port onto the head.
