how to identify motor

[tegguy]

I am looking at buying a 240SX off someone here and it supposedly has a RB20DET motor in it. I am new to nissans Can someone tell me where on the motor it says what it is? I know where it is on hondas but this is my first 240. perhaps a pic to show also

there will be a "rb20" stamped on the upper timing belt cover if its a rb20det (duh) as well as the coil pack cover says "Nissan 24 valve..."

rb25 has no stamp but the coil pack cover says "Nissan 2500cc"

rb26 has a similar stamp as the rb20 ...

Some RB20's don't have the "RB20" stamped timing cover. RB25's have a extra hump on the timing cover and coil cover reads "TWIN CAM/24 VALVE/2500 NISSAN"

Also u can check out the ecu...It'll read something like MEC-r212...

But if ur scared that there's a ka in it just count the cylinders...So long as it has an inline 6 turbo in it, u should be fine...

Its real hard to mistaken an rb for a ka

also the manifold says "eccs" ( or something like that) on the top.
