I'm trying to compile a list of the 'hidden costs' of the TBI-TPI swap, not to discourage people from doing it, but to let them know what they're getting into. I know many of you know scores more than I do about this, so let's help everybody out by putting our heads together. Thanks!

Cheers,

James

 

Hidden costs for me was $60 for fittings to adapt the fuel rails to a 3/8 and a 5/16 hose barb, but if you're using an intank pump and stock lines this should not be a problem.

Anther small hidden cost was brass 1/8" NPT fittings to make a new riser for the oil pressure sensor that didnt interfere with the intake manifold.

Also a hidden savings was that my car already had a map sensor mounted on the drivers corner of the firewall.

 

Thanks, see sy2449's post below (getting ready to try a TPI swap) to see my input, and respond to that thread. That way we don't start repeating information.
