Re: Hey all new lad needs some help!
Hi Chris, to clarify;
3sgte and 3sge camshafts are interchangable as in fitting in the 3sgte head. They have different lift, timing and duration, altering the valve movement / air&fuel let into the engine aka engine characteristics. Aftermarket camshafts are also a great improvement in engine performance possibilities where the engine is modified.
Any change in camshafts needs to be matched with supporting modifications that vary depending on camshaft profile and boost. Some basics include adjustable cam gears, valve clearances checked, cams should be professionally dialled in (not just the cam gear says so), and must be dyno tuned by a professional dyno tuner who will adjust the degrees based on the data from the dyno and there expertise in tuning (if you want power earlier or later). This is not a do it yourself / Google told me so.
Shaking engine is hard one to diagnose on forum - how much shake, at what rpm, at what boost. Many checks come to mind to narrow such as checks on fuel pressure, oil pressure, compression and leak down test, fuel injectors (what are your running) and other aspects. Can PM through a few more details, however with your investment best see a professional dyno tuner.
Australia is a big country. In January it's normal to see temperatures as high as 40-45 degrees Celsius during the day, some parts hotter and some colder.
