Easy Way To Identify Neo Head

[33_drift]

The only thing close to a number that I can see is stamped at the rear of the head and I’m pretty sure it’s covered

NEO heads have the front head drain blocked off. Non-NEO heads have a steel drain that goes back into the block.

Spoke to another guy on Facebook and that said the same thing, cheers for the reply

Above exhaust ports 2-3 you should find a number cast, 5l8 for turbo neo and 5l7 for non turbs

It must just be my anti-R33 bent, but I would have said the easy way to identify a Neo head is it will be under the bonnet of a good car.

I’ve still got to pull everything off the motor to see it, factory manifold is in the way I’m pretty sure it’s non-neo though

Also non-NEO 1997 and 1998 R33 GTS-t has the black CAS

Non neo has a four bolt plate on the vct cam pulley, neo has a single bolt. If no cams are installed the non neo will have two big oil feed holes for vct in the cam journal orientated transversely. The neo will have two small oil holes orientated longitudinally with the head.

So I have a stagea that’s blown a head gasket and I’m looking for a head, I’ve looked for the casting number in the place that’s specified and there’s no number that I can see, is it cast into the head or stamped

Would you sell your old neo head?

From all the info I’m getting, mine isn’t a neo head

[iruvyouskyrine]

Then why do you want a neo head to put on to it? Neo head on non neo bottom end = bad times

R33 Has a metal Mitsubishi CAS 23731 02U11

Neo has plastic Hitachi CAS 23731 5L 300

Are you sure your head can't be repaired?

Providing no one has changed it, neo cam covers do not use those bolts with the bolt seals either

I don’t want to put a neo head on my motor, I just asked the question to make sure I didn’t buy the wrong head for my car

[iruvyouskyrine]

ohhh makes sense, my bad!

All good, just in the process of pulling everything off the turbo side so I can get a look at the casting number and order a head

[33_drift]

So the casting number on my head is 75T 4, pre neo yeah?
