Hi all. I'm not exactly sure what is on topic in here, appologies if
this is not.
I am converting a car (a lotus) from carbs to fuel injection. The
throttle bodies I'm using have a slightly diffeerent bolt parttern to
the carbs, such that there is enough 'meat' on the flanges, but the
holes are too big and about half 'a hole' out, if you see what I mean.
I'm thinking about filling the existing stud holes in the manifold with
JB weld to effectively make flat undrilled flanges and then drilling and
tapping that. This will mean the drill/tap will be working half in alloy
and half in jb weld.
The jb weld packet seems to suggest you can tap it - in reality does
anyone know if this will work?
Should I go for a course thread like UNC, or a finer one (metric or
UNF)?
Cheers,
Conrad
