MG Midget and Sprite Technical - star drive or slot drive

hi, quick question, how do i know if my oil pump is star or slot drive? I'm thinking about camshafts, I've got a 73 RWA midget, thanks in advance

Does it realy mather?

When you have the engine out to change the cam and folowers it is not that mutch extra work to change the pump as well.

I'd check the bearings as well since you have it upside down with the sump off.

All parts that do not cost a lot but cost a lot to change when the engine is still in.

Just like the clutch.....

As Onno points out when you change the cam you would probably want to change the pump anyway.

Normally you would purchase a slot drive as this is by far the most common type in modern use. If you want to change to the higher capacity pumps these I think only come in slot drive.

Im not sure they even make a star drive anymore...

Buy an SW5-07 Cam Kit from Swiftune.... It will come with oil pump.

I went the swiftune approach... and vary happy I did, whats great is you get everything at a vary good price

I got the roller tipped high lift rockers, springs, veneir sprockets/chains, camshaft, degree wheel, oil pump and several other things i cant remember... takes all the guess work out.

The only draw back is you dont get any specs... only the timing degree spec which is 116

I did find these specs recently... Un-fortantly I dont remember the source, so just remember ... I read it on the internet. So it must be a fact.

Opps Sorry! ... I forgot my spec book at the shop, Ill post the the swiftune SW5-07 cam specs tomarrow.

And happy you did Prop? why?
Did it make your engine rev brilliantly?
What is your BHP figure at 5000RPM?

Or did simply look nice?
