Hi all,

Just started putting on my stage 1 kit from minisport, and found that the inlet gaskets aren't included. And after buying one, I realised that I need two because there was a spacer attached to the old manifold.

I've just cut one out of some gasket cork, but I've noticed that the minisport inlet manifold has a larger hole. I'm using an HS4, and the manifold is also compatible for the HIF44s which need the bigger hole.

Should I just cut the gasket hole a little bigger? No big problem, I'm just not sure what's usually done, and I don't think having the gasket hanging inside the manifold is a good idea.

(Sorry about all the recent topics I've made - I want my mini back on the road!)

so you're fitting a HS4 (38mm) to a new manifold with a 44mm bore? probably not a good plan - I'd be hunting down a HS6

however

I'd put the 44mm hole gasket on the manifold side of the spacer, and the 38mm hole gasket on the carb side

I bought a stage 1 kit for an HS4 and this was just the one provided. I actually have 6 Hs6 carbs lying around but none of them are in working condition, and I want to keep the fuel economy. For a 998, I understand that an Hs6 would be too much anyway.

By the way, does anyone know what the threaded hole leading into the inlet manifold is for? I know the two pipes at the side are for the water cooling, but it looks like I'll just have to plug up this hole unless it's for something useful.

The threaded hole is for your brake vacum connection (if a vac unit is fitted!), otherwise just put a suitable bolt with sealant in to block it off.
