James-
I think it might be harder than you think to aquire all the parts
necessary to convert a car to "original" PI spec. -- I know the
folks in Endland won't part with PI manifolds or control units
without an exchange...
Do Canadian spec TR's have PI ? I know the stuff shows up in the TRF
cats but is it really available? Just to buy it outright without an
exchange?
I've thought that the hot set up would be to use the PI
manifolds and adapt them to EFI... parts for any modern 6cyl ought to
work nicely. There is a website listed on the SOL website with
exactly this info... I think they want $1600 for a EFI complete set
up..
PS: I just did my emissions check this past Saturday and I passed
Hydrocarbons by a factor of 5! With worn original SU's...
