Tomei Poncams On R34 Neo *info Plz*

[loksta6]

Hey i was just wondering if some 1 could shed a bit of light regarding fitting poncams to a neo R34

I have been informed that the head needs to be removed to get the tappet adjustment correct

and that also the springs have to upgraded no matter wat cam you use?

What im wanting to know is has any1 just bolted them in or is this do-able? have they needed shimming at all?

I have heard so many mixed storys about what u can and cant do or if u can get away with bolting them in and checking clearances ec etc

so if anyone has some info on this for me would be much appreciated! cheers.

Hi mate i used the 262degree 9.15mm lift neo poncams and i bolted them straight in. The shims sit on top of the buckets in the neo not under so setting the shims correctly is easy as, but i found i didn't need to adjust any maybe i was lucky??? as for the springs tomei say you dont need to change, i didn't and found no probleme. hope this helps.

i used gtr tomei poncams for my neo head which needed shimming. Changed to heavy duty springs aswell. Depends how high your rev and what level of boost you use.

to get the tomei valve clearances with 260deg type poncams we needed shims.

Bolted straight in. No shims or springs needed. Runs like a standard engine just slightly noisier.

cheers
