Im looking for a standard location on an rb26 to mount my knock audio sensor. i know where the “ideal” locations are but dont seem to find anything good. Other than dismounting a factory unit or using the upper rear engine mounting bolt Im wondering if theres a common practice with these engines that yields good results? any help is appreciated.

i personally use the z shaped bracket left rear of the head the bracket is factory bolted to the head with two bolts and has two open holes on it I use one of those holes. on some gtr engines, there is a spare 10mm bolt hole on the block behind the ac pump i have a drilled out knock sensor and on others I use the bolt the holds the coil bracket down in the centre.

Regards Ross

ok thanks. I guess i dont know how typical is to use the cylinder head in practice.
