[RB SANDY]

I have a rb25det in a r32 gts-T how can I tell if it is a series 1 or 1.5.

black box on the back of the rocker covers.

If you have one. Series I motor.

If you dont, series II motor

[WazR32GTSt]

you mean series 1 or series 2

there's no such thing as a series 1.5

just something SAU made up to make later model series 1 owners happier...

[RB SANDY]

I know the direrence between the series 1 and 2 but not 1.5

[FORZA-MOTORSPORT]

Doesnt series 2 have the r34 turbo, which has a black plastic front wheel, series one has a steel front wheel easy to see difference, didnt know there where 3 different r33 series how does it go with the extra torque??

I know the direrence between the series 1 and 2 but not 1.5

there is no 1.5

series 2 have 3 bolt coil packs.

series 1 have 4.

I don't believe series 1 have variable cam timing

As R31Nismoid said...no ignition amplifier present on series 2

[Guilt-Toy]

the series 1.5 came out in 95 only i believe - check your coil packs and follow the plugs that plug into them. If it plugs into a square box that has another plug connected to it going to the engine harness then its a series 1 engine.

If its just pluged into a plug with no square box then its a engine wich is a mix between series 1 and series 2

Its got coils with ignitors built in and it does not have a plastic front wheel on the turbo but still has ceramic rear (same as series 1 turbo)

[paulr33]

looks like a series 2 engine

[nizmokid]

well my car is a r33 series 1 style ....but it has the series 2 motor in it , the car was made in late 1994....so what have I got a series 1 or 2 ...or the rare SAU 1.5? hahahahah

.....oh this is the motor which was made with the car! not dropped in after!

[Lazy-Bastard]

looks like a series 1 to me going by the colour of the AFM sticker......don't S2's have pink ones?. My S1 has a green one

[Lazy-Bastard]

I don't believe series 1 have variable cam timing

they do

[paulr33]

doh, good spot. didnt think of that

[Munkyb0y]

they do

yeah i thought series 1 had variable cam timing too.

also this tps plug not used on S1 manual, but is used on S2 manual. Dunno if that applies in the R32 setup though.

thats a series 1 motor. series 2 have a rounder tps, and it has 2 plugs (although both not always connected).

as for the series 1.5, they weren't a true model, but just a mix match. they have a series 2 wing, series 1 interior, series 1 bodykit, and most have a series 2 motor, drivers airbag as standard.

series 1 or 2?

[mad082]

1.

telling if it is a series 1 or 2 by the coil packs isn't 100% accurate because the person may have changed the coils. but it is less likely that someone has changed the TPS.

I know that the car has an Igniter and the afm was changer with the old rb20 one.

can any one tell me the year of the motor I can take more photos if wanted.

[mad082]

bit hard to tell the year. but if it is a series 1 it is more than likely a 93 or 94. small chance it could be 95.
