Just wondering is it true that you can use certain bolts from a diff for the plenum chamber? Im about to buy one without bolts, but i have a spare gearbox and diff. Is there enough bolts on one diff and gearbox?
thanks

Or just measure the length you need to go through the plenum chamber, and order some appropriate bolts for it. Thread into the carb is 5/16 UNC I believe.

Namrick can/will supply pretty much anything you can dream up bolt wise.

You could tap the holes in the plenium M8 I think,Drill the holes in the carb bigger .Then you can bolt the plenum to the carb from the carb side....making it easier to remove and refit whilst it is in the car.

Not my idea I think Dan(lincoln) has done this mod

If they're 5/16 UNF in the beginning 8mm is not possible.
Also, leave metric screws AWAY from Minis!

prob m10 then,The screws that hold the heat sheild on the back of the plenium are m6 so go with the flow.

Also the spark plug thread is metric*tongue*

Sold the turbo and seeing what the C20XE can do!

I cant see the problem with using metric threads, in fact the next engine i do i may well use metric all the way through it.

Good reasoning behind this is i can get top quality nuts and bolts, anything i want for free *smiley*

The problem with metric studs is that during hte next rebuid everything gets thrown in a pile, and when rebuilding you use the 8mm bolt a different place. We've all experienced this. If we stay imperial, this will never happen. :)

So... I get the 2 holes in the plenum tapped to a M10 thread, and i drill out the carb holes to the m10 size too??

Sounds much better if i can remove it easier in the car, and im thinking of droping the engine in without the plenum on this time last time i had to tilt it away from the scuttle.

I dont throw bolts in a pile when i take me engine apart i always put the bolts back into the holes loseley, or tie wrap them to the part or something, otherwise its inevitable they they get lost!
