Tomei Poncams

[Get EPIC]

Hey guys, ive got about 250 rwkw on my r33 and was thinking about sticking some poncams in. What difference would it make to power delivery? Would it make much difference?

[Reflector]

I have mostly everything stock on my RB25DET but I love the sound of upgraded cams and wanted some extra power. Put you in perspective. Car previously made 204rwkw on dyno before upgrade. After poncam upgrade and a 100cpsi cat the car now makes 214.8rwkw. So there's not a huge difference for the money, BUT, my torque curve improved more and is definitely more noticeable through mid range RPM.

All in all you'll get people telling you they don't make a difference and there's no point upgrading or others saying it is worth it. I consider it a good mod and I personally love the sound of my car after the upgrade

Thanks for the reply mate. I might get them as i have pretty much done everything else to my car that i want and see how it goes. Cheers

Peak power will barely change but that isn't he purpose of Poncams. Midrange torque is where the main improvement will be.

Is it worth the money? Depends what else you could spend the money on.

Yeah as other said mid range its worth it. After adding poncams and e85 I gained 30-40 kw everywhere throughout the rev range and improved repsonse so I would say there worth it. Just remember to do your valve springs while you do them.

I had these installed on my RB25.

After picking the car up from the workshop I was slightly disappointed, since the 'improvement' was barely noticeable.

Also I could not hear any difference in engine sound (contrary to what one user wrote here)

I got the cams for a good price and my cambelt was due for a change.

So I went for the whole package (while at it)

I doubt I would do this 'mod' again, the $$$ are better invested in a stronger turbo.

Still, if you can get a 'pair' on the cheap you might go for it (while doing the cambelt).

The cams will definitely not hurt performance, and possibly in connection with all the STAGE II mods they make more of a pronounced difference.

I installed them for mid range and fuel efficiencies. Not sure if they made any difference because I also bolted in a 3076 and HKS cast mani at the same time. I've still got my std cams and have toyed with the idea of swapping them in and out for back to backs - but to be honest ICBF. I'm still going to use the cams, they are already in, and I just don't care enough to do it [plus you can snap a stick if you don't watch it].
