Uprating Mk1 850

[stigproducts]

I have got an 850 Mk 1 and would like to fit a bigger engine- it is
quicker to walk right now!
I am thinking a 1275, and obviously some suspension and brake mods to
go with it. before I start I am thinking will a new engine and subframe
from a later car just fit straight in or are the early/late shells
different? I apporeciate even if it does things like cables will need to be
reouted differently. I keep meaning to go to a big mini show and ask around-
maybe you guys can get me started?

Thanks, yes it is a very early car with all the things you mention, 36,000 miles in the family from new!

I wonder in light of what Phil has said then if the engine-subframe mountings are the same? Could I keep my subframe and drop in a later engine?

Any other advice gratefully received.
