New project, 2002 Chevy Tracker ZR2, 2.5L with no timing on the right (#1?) side. I'm pulling the engine and swapping in a 2.7L engine from a wrecked but running 2004 Suz XL-7. The 2.7 is basically a bored out 2.5 but with a couple of important differences.
There's a thread posted on an Aussie Zuk forum from the mid-2010s that comes very close to my situation. The poster said this is the "easiest swap ever". You swap in the 2.7 short block but use your Tracker's 2.5 ECU and all peripherals (except you can use the XL-7 alternator). Two exceptions however: the cam position sensor and the knock sensor apparently do not interchange.
There's also a "2.7 swap" link in the FAQ thread in this forum, but i didn't see where it answered my questions:
First question, kind of a simple one. Can I just cut the 2.7's knock sensor wires and leave it dead in place when I drop it into my Tracker? I'll confirm when I pull the old engine, but I don't think the 2.5 Trackers in the USA used a knock sensor. So I figure I can just cut the 2.7's knock sensor wires and leave the sensor or a plug in place. Right?
Second question. Do I use the 2.7 or the 2.5 cam position sensor? Also I understand that some recalibration may be necessary if you remove or replace them. And there's a torx screw on the side of the CPS that appears to be a set screw of some sort. So I use that screw for the recalibration or ?
Thanks for any help.
