[skylineboy84]

Nope, the Greddy RB26 clear cover wont fit over variable inlet cam controller on the RB25. You will notice a bulge on both the left and right side of the RB25 cover. RB26 cover has a bulge on right side only.

I bought the Greddy cover thinking I could heat the plastic and a make a second bulge. This would have worked okay on acrylic but turns out this is polycarbonate which tends to bubble badly. It could possibly be done using proper blow moulding equipment, however the shape is also completely wrong.

I turns out the clear greddy cover is about an inch too short (leaves a gap at the bottom where dirt can get in).

Also does not match profile of cams and leaves a gap at the top.

All in all the GReddy cover is not worth the hassle of fitting.

The good news is you can get a clear cover made exactly to fit the RB25 from PSI parts made by sniper racing.

I havent fitted it yet however I have had a good look at it.

My only comments are that it is a bit more flimsy than the GReddy cover which is fairly strong. I would say the plastic is about half the thickness (say 3mm compared to 6mm). Given the cover is not subjected to any load I would say it should be okay. The surface finish of the RB25 cover is not quite as good as the Greddy cover either (but still acceptable). Greddy cover is high pressure injection moulded in a polished die. The RB25 cover looks to be blow moulded over a female mould.
