hey man, ive got a picture of the intake manifold bolt pattern, ive been doing some research and as far as ive got is thinking this engine may not be a rb25 but a rb20....it has red temp sensor on the radiator hose, looked up the CAS model number and its saying its an rb20 one...but it seems to be running indivdual coilpacks and I know the rb20's never had these, ive attached pictures of it, see what you think...
