anyone have a how to on the scfi to mpfi swap?

things like the part numbers would be espically helpful. thanks

 

I do believe i have posted part numbers before. Are you wanting to do it for performance reasons or to replace a faulty SCFI unit? Cause there will be pretty much no performance difference.

Anyway, here's where I posted the PNs:

i have a faulty unit in my blazer.

thought it might be the converter causing my bad fuel milage/stumbling/etc but i punched the honey comb outta the cat this past weekend and while the truck now runs better....... its still has the same problems jsut not as severe.

 

i thought there was a bracket that needed to be replaced as well...... and also a "nut kit" or am i wrong and do i just need the mpi for my year blazer

 

If you have the newer SCFI (plastic upper plenum), then all you need is the MPFI spider.
