Rb20det Difference Red/silver Tops

[mr-r33]

hi guy just want to ask if any of you can tell me how to spot the difference in the RB20DET red top to the silver top

iam maybe geting a car that has a RB20 in it but when i asked the guy if he knows if it is a red top or silver top he said i'm not sure i think its a silver top

any way is there any marking on the block/head that would tell me what it is...i know the rocker covers are difference but not hard to swap red for silver

[Wheezy]

intake manifolds are different, fuel rail is more like an rb30 on the redtop, it has hose tail injectors. If the inlet manifold says NICS it is def a redtop, there is an ECCS variant.

Best look at R31SkylineClub for the differences, there are plenty of threads about them, redtops came in the HR31 import from japan among other cars.
