RB26 camshafts in RB20??

[crayman]

I just put 33 GTR cams in, takes about 30 seconds to start and idles just like that video of the maroon S13 only hunting up and down with the idle screw almost all the way out. But seeing as all the hard work of removing my rusted on harmonic balancer and seized cam caps, it's not that bad to pull it apart again to chuck some RB25de cams in I have lying around. I may even mix and match the RB20 exhaust cam with the RB25de inlet cam as they have different lobe separations

How has the power delivery changed?

Hmm hard to tell, I'll chuck some new plugs in tomorrow as it's misfiring under load (coilpacks are average too) Free revving it makes the turbo spool faster, but I find it rather doughy off the line (worse than a stock 20, which mine is!)

sounds like all that happens is you get lots of boost/fuel blown out the exhaust ports at low revs and high revs its only slightly better from what I've read.

I would put money that the average power has actually gone down.

rather than making a new thread that's kind of on the same topic.

I want to buy a set of used R32 GTR cams (but don't want to get screwed over). Is there anyway to tell that they are R32 GTR cams? Do they have particular markings so you would be able to tell the difference to say a set of RB20 cams or other cams?

I have some still sitting in my new rb26 if your interested
