Which Model Is My Engine

[Eatan8]

Hey Guys.

Im lookin at getting a set of Tomei Poncams for my 1996 Gtst but i dont know in which month it was made i know in late 1996 they changed the CAS which changes the S1 and S2 cams and was just wondering if there is a way of checkin without opening anythin up. I looked at the import papers and plates in the engine bay and couldn't find anythin if i miss read the plates or there is another way 2 check it would be great 2 know.

Cheers

S1 motors and S2 motors have a different coil setup.

Just go via that i think is what most do.

S2 has no ignition box

I thought that the difference was with the cas eg. silver for S1 and early S2 and black for late S2 - on

Late S2 in pic below..

easiest way to tell is coil pack setup.. if it has a ignitior it is series 1 if it doesnt its series 2

hmmmm my engine was a series 1 but it has no ignitor pack? and its got the silver CAS? but yeah my mech converted the coil pack thingy

think for poncams the change over time was 07/97

if unsure i would go for S1 cams - as they are 1000x easier to sell if they are wrong versus the S2

plenty of people have been stung with this problem and im sure there are cams out there in sheds that cannot be used.

build date of the car is on the Vin/chassis plate above the brake booster

+1 for being stung.My car was built in sep 97.And i ordered the wrong cams.If you car was built in 96 then you need the "series 1" cams.Even though both your and my car are series 2.
