Thanks for commenting on the article! We have done a lot of work on the e36 to make some very trick things reliable for both street and track!

This is the 'cam kit' that we developed with Jim Conforti and Josh (Eurosport). This kit is rock solid and is truly awesome! The car is transformed - street or track. Good news for 2.8 and 3.2 owners as well the kits will be available for these motors too. Also, we have a 3.6 stroker and two different SC designs (a centrifugal and a roots) coming out!

We did not either - so we said let's try to do as much as we can for a CCA CR HP car (which limits the mods to bolt-ons (only cams can be changed internally). We used mild cams that were chosen with Will Turner's help so that we could truly recommend this kit for street use and lose minimal amounts of torque!

Yes - we will not change the crank pulley. We lose some power gains, but it is reliable!

No worries - the cams are not that high lift. We (evosport, conforti, turner) have had ZERO problems over 16 months with this cam kit on 20-30 race cars with stock springs. You cannot replace them in HP so it was not an option. However, you can most certainly change them on your street car for preventative measures.

Wait till you drive it!

Thanks! And if anyone has any specific questions, please e-mail me directly with any questions! I don't want to be too commercial on this list. E-mail
