RB25DET series 1 and 2 visual differences?

[GTR-Ben]

Is there any way to tell by looking at the engine if it is a series 1 or 2. I know the ECU is different and one has a ceramic turbo while the other has plastic.

Can you tell by looking at the VVT?

Ignitor..

the throttle body piping is different between series 1 and 2

The coil pack's are differnt.

On the series 1 their is a little box at the back of the motor and on series 2 their isnt any little black box.

The CAS looks a little different to the series 2. - only minor features.

The colour of the engine rocker covers. Series 1 are darker cover and series 2 are shinier silvery colour.

Look at the Nissan Japan Co manufactory plate or compliance plates

You can look for the ABS system in the right hand conor of engine bay. - Series 2

The rear wing and body kit is different, steering wheel is different, seats are different 1995 - 1996 mdls.

Air bag on series 2's

I carnt think of anything else.

Not quite right. Many series 2's don't have ABS. Mine included. I'm sure there is a thread on differences in the FAQ section.

Is it an option from the factory in the series 2 1996mdl + ?

It's just an engine, it has been painted, and it dosn't have the intake pipe to the throttle body..

But it has an ignitor pack (little box as cameron called it.) so it is a series 1 which I worked out after making the first post about 10seconds later..

Just dropping it into a GXI for someone.. only wires that look different are the under dash ones it has a multi junction where the earlier nissans have a smaller plug. Anywhere on the net to get the diagram from the RB25T looms, not just engine loom?

I have done a search, looked through the FAQ section and havent been able to find any information that says that S1 parts can be used on s2's and vice versa.

What I want to know is.

1. Can a S1 coil loom and engine loom be used with s2 coils.

I'm using new splitfire coils for a S2 and the s1 plugs dont fit.

2. The coil cover has an ignitor on the top, at the back. This is a series 1 part?.

Looking on the underside I noticed it has 10/94.

3. Are there different versions of PFC's for each series?

On the side it has these numbers. PFC RB25 9910-0035

4. Is there any markings on the head to identify what series it is?

The guy I bought the engine off said it was a S2, but after finding the coil plugs not fitting onto the S2 coils I need to know exactly what I have.:slap:

I thought I'd better sort this grey area out before i buy any more wrong series parts.

Does anyone know or will I need to do my own research to find out.

[GTR-Ben]

If it has an ignitor, then it is a series 1 RB25DET.

I believe the Series 2 coils have a built in ignitor like with the S15 SR20DET engine.
