i think this has been cover before, i believe you will need to fabricate an adapter or something.

the flange is completely diffrent, so you either have to redrill the rb20's head or like 240slidekat said make an adaptor.itb's are nice to have for sure but doing that swap is just a pain to do it.

Blitz Makes an adapter plate for like 250.00. Other wise the only guy I know to have done it without buying the plate did it by doing alot of chopping and welding. It is functional but looks 3rd rate and quite ghetto fab.

Lets not forget the port size of the Rb26. The intake ports are freaking huge vs the Rb20. The 25's are a little bigger than the 20.

http://www.watfordmotorsport.co.uk They have the hook up for parts apparently

E-mail this guy, he says he can make one with no [email protected]

It is not such an original idea that it has not been done yet so there are quite a few things out there.
