The Honda PCX / Forza / ADV150 / SH Forums

Hi all!

I might be doing an efi conversion on a non-pcx engine (139qmb) soon, and I want to use the intake manifold from the pcx as an efi-ready replacement. One of the major snippets of information I have been trying to gleam from google searches is the center-to-center bolt hole spacing on the engine-side of the intake manifold. The engine I have, has a bolt spacing of 45mm.

There will be more tidbits of info I will need in short order, but one thing at a time. Thanks in advance dudes and dudettes!

I have a spare engine that I will be rebuilding eventually. Let me know what you need to measure.

So far, the most pertinent measurement needed is the bolt hole spacing I mentioned above. After that, it would be the pinout (what color wire goes to which physical pin) for sensor unit on the TB.
