RB25det engine identification

[Rbpatrol21]

Hey guys new to the event life. I recently bought a patrol with a rb25det, the previous owner gave me no information on what model the engine came out of the engine number is rb25242462a can anyone tell me exactly what it is so I can order some new parts 

[iruvyouskyrine]

number is not helpful. post pics of the engine especially near the exhaust manifold of cylinders 1/2/3, the coilpack valley, and near where the top rad hose goes into the engine

[Rbpatrol21]

The coil packs I put in are the same as the picture 

[iruvyouskyrine]

Its either late R33 or R34 neo engine. Take a picture of the coilpacks on your car, and the area around the front of the exhaust manifold as well to confirm 100%

As above. But what do you want or buy?

How are your intake temps? Tip mount intercooler seem like a poor idea.

Looks like a late s2

[iruvyouskyrine]

S2 didnt have plastic CAS and still used the coilpack mounting brackets

[WMDC35]

Hard to say from the pics, it could be a mix of what they had lying around, late s2 does have plastic CAS, it hasn't got the neo ps pump.

As you say see if it's got the drain at the front of the head, might not matter depending what parts are needed

[iruvyouskyrine]

Are you sure? I have only ever seen R33 'S3' with the plastic CAS, they also have the R34 ECU header plug and the coilpacks mount directly to the head, but still hydraulic lifters and no VCT drain.

If your VCT is working R33 changes at 4500 R34 at 5400

[WMDC35]

Seems to be mixes towards the end, looks like a 33 type though with the intake, side feed injectors and ps pump etc

I thought it looked more S2.5+ than Neo, but photos aren't sufficient to convince.

It certainly does not have the R34 Neo throttlebody on it.

If it is a vanilla RB25, then it will have come out of an R33 Skyline**. If it is somehow AWD in the Patrol, then it would have come from a Stagea**.

There are a couple of other choices of vehicles that the engine could have come out of, but not to the extent that it would make any difference.

Was going to say it looks like my '98, so the last of the R33's, but the timing cover behind the CAS is different and much bulkier.  It has a larger flange and that webbing that mine doesn't have.

Looks like its lost some coolant more than once as well - all that white dust.

[WR33KD]

Could be a neo and they have changed the intake. Don’t s2 have a pressed tin cam cover not plastic?

[Duncan]

interesting conversion. probably goes way better than my td42 one but I suspect an rb25 will still struggle moving all that weight.

surely it is 4wd....if the original engine was td28 it is likely all the original patrol 4wd stuff bolted right up.

[WMDC35]

C34s can be a mixed bag, anyway looks like the OP has gone

25 Y60s seem to go pretty well surprisingly
