because your valve stems are shorter.

listen: you're more than likely going to fuck it up. i'm not going to say you ARE, because in the event that you happen to be, maybe remotely even close to being a badass like me, then you might be able to make it work.


Here's the main sitch though.

the GTI-R rocker geometry is off. that's why the JUN stage 3 and th Tomei solid pivot cam lobes are so different in their base circle geometry vs regular SR hydro cam stuff. that way they can work in the GTIR also.

good luck.

i'll be the first one in line to laugh WHEN it explodes.
