R32 -rb25 Computer ?

[4hirpm]

im looking at geting a power fc for my r32 wich is running an rb-25 i am unsure if it is a s1 or s2 engine and computer as it seems to be running the stock r33 computer.

If anyone no's an easy way of telling the s1 and s2 computers and engine apart it would be a great help

cheers

no matter dude, pfc for a s1 and s2 skyline rb25 are the same

having said that another easy way to tell is have a look at the back of your spark plug cover and see if there is a lil alloy box with heat sinks on it, thats your ignitor module and is only on s1 engines, if its not there its a s2 which have the ignitors built into the coils themselves

Would be interested to know what mods would need to be done to run the 32 on a 33 ecu. Not that I want it done, but I have a rb25det in my 32 and it seems to be running on a chipped 32 ecu.

Do a search for posts by carl h He runs an rb25 pfc on an rb20 in the US and had to swap a couple of pins around (either injectors or ignition, can't remember)
