rb25 neo coilpacks on s2 motor

[jbballa9876]

I am considering the possibility of using neo coilpacks on my s2 motor considering i might be able to trade s1 coilpacks for a set of neo and save some money.

I have researched and found the s2 and neo have same plugs but different mounting holes. And neos doesnt have a coil rail but bolts directly to the head??

Does anyone think using the neo coilpacks will be too difficult to be worth it or think its no big deal? im nearly 99% positve the coilpacks are the same otherwise but please correct me if i am wrong.

Thanks for any input all is appreciated.
