Truth or fiction?- RB26 cams in a Rb20

[RustspecS13]

I have a friend that will have stock rb26 cams I can get a hold of cheap/possibly free and Ive heard they are like a 20-30whp bolt on.

I looked in my fsm and they are a little bigger, but I think they are solid lifter instead of hydralic.

Any way, my main point is there proof that they make more power then stock? Any one have dyno charts?

mainly fiction, some fact.only the r32 cams work and even then you need adjustable cam gears to reset the cam phasing.it will never run 'right' because of the lobe design as it was intended for solid lifters not hydro which will not have the right ramp rate.

yeap i second that motion lol. someone on this forum i believe tried that and it didn't work so they put it back to stock.. but to make it work you gotta do alot of thing like he said . but if you change the lifter and get cam gears . and you cas wont work.. not worth it.!!

Ah ok. So could you use stock RB26 lifters then or would they not fit/require machine work? I'm just curious how some people got "good results" from doing it.

But then your CAS timing is still fubard and you'd have to rotate that into the right position. Hmm.

machine work and lots of it

they didn't

Blah screw it Im going to put a VQ30+T in F it. Torx and rpms near what the rb20 can do. Its also aluminum....

I think you'd be a lot happier with a VQ30 over a RB20. Gonna be a tight fit though, right? Bad a** for sure.

[RustspecS13]

Its not that bad from what I've seen....the rb20 is staying in fornow. But my eventual goal is VQ30 in the daily and vq35 in the track car. plus then i get a super strong 6 speed from a 350z. Instead of the weak KA/SR/RB20 box.

It'll pretty much be 6cyl nissan power for a while.....:-D

kind of late but.

Is it do able yes, but its not practical, as stated above you would be putting a solid lifter cam onto a hydro lifter. The lobe ramp is designed diffrently for the solid and hydro lifters.

And you only gain little bit of lift and some duration and IIRC Ex duration on GTR is less than that of Rb20(but that's from the top of my head).

You would need GTR32 cams, (adj cam gears are not necessary to get it running) but to get the optimal performance. You would IIRC need to retard intake about 2degrees and advance exhaust dont remember how many degrees, this is where adj cam gears come in handy.

There is a Ausi forum that people talked about it. Some broke/bent valves. So I'm not sure if this truly works.

I have a set of R32 cams In, Ex, that I was going to put into my RB20.

And you can buy solid lifters their only about $450, and GTR cams you can pick up for around $200 for set. And adj cam gears cost usually $280+/- depending on brand.

This is a video from that Aussi forum that someone posted, somwhere in USA(Missouri?) 240sx with Rb20 and Rb26dett cams think he was running Hyro lifters and non adj gears. Anyway it was while back when I was looking at it, but I went a different route.
