Rb26dett Cams Into A Rb25det

[super_s13]

They did say however there is some machining needed for the VCT do you guys/girls know what exactly needs to be done. Or will it stand out when the tuner puts them in. Also what kinds gains could you expect. I only ask as i can get a set for 150 off a mate that has replaced his with upgraded items ages ago.

but u can get a decent aftermarket exhaust cam gear new to suit your car at that price... thought that would be better then trying to ge t them to fit?

[rev210]

waste of time.

They are solid cams and unless you have a Neo that means no-go.

[super_s13]

The artical said if you have a neo there is no point. There pretty much the same they reckon. So dont do it then?

and tell your mate who is selling them for $150 to stick it cause they usually go for ~$50 on the forums, I got them for free off a member cause nobody would give him money for them

Ramp rates on the lobes are different for solid and hydraulic setup so you would either need to convert your heard to solid lifter setup ($$) or have the cams reground to suit hydraulic lifters.

That being said I have heard SK puts them into RB20's without any modification for good results

[bubba]

From what I've read of 26 cams in 20s with no mods, there are some idle issues as the valves are opening/closing sooner/later due to the ramp rates. I was applying this same theory to 25s because they both run hydraulic lifters.

If it is able to be done without any mods, then someone please say so as I have looked into this several times and come to the same conclusion - that it's not a drop in affair.

I tried dropping them in an rb20, and it lost about 80% power up to 4000rpm, when we decided to pull them out
