if i was to start with say an LS or something and wanted to swap in a B18C5, is it a direct bolt in? what would need to be added/modified as far as:
vtec
iab
axles
mounts
other wiring
etc

thanks! btw i did a search but didnt find much. i guess B18C5's are expensive

 

The motor is a direct bolt in, and you can use any 3g integra axles. ITR axles would be best. All 3g integra mounts are the same except the ITR mounts are a little stiffer. There is no IAB on a b18c5, only on h22a's and b18c1's. IAB = dual stage intake manifold, b18c5 = single stage.

As far as wiring is concerned, you'd have to add knock and vtec wires I believe to the LS intermediate harness for the ITR harness to plug in and work properly with the ITR ECU.

 

sweet i was hoping it would be as simple as that
