N55 335 to N55 435 JB4 swap?

BMSe92 · 04-09-2014, 12:21 PM

Thinking about trading in my 335 for a 435. Is it possible to swap my stage 2 JB4 from the 335 over to the 435? Or does it require a different harness

Pretty sure it works for both the 335/435/535. I would double check, but I think you should be all set.

Yea I figured the unit itself would be the same but wasn't sure about the harness. I'll call burger and confirm

E9x to F3x the wiring harness length of some wires may be an issue.
terry told my my buddy looking for an F10 535 that a 135 wouldnt work.
but wouldnt say why

It very well may be different. I believe all of the 4 series use the electronic wastegate.

Best to ask BMS.

Since you're going from N55 to N55 (presumably both F series), it should be the same and you wouldn't hook up to the solenoid (since the 435 is electronic while the 335 was pneumatic if it was a '12 or early '13).

They haven't yet released the electronic wastegate connection as far as I know yet and it's still in testing.

Take all that with a grain of salt, but that's the general idea that I've gotten. I dont have stake in that game so I could be wrong on the details.
