Yes you can do that but after that you should have a cam pulley in order to adjust the timing, if not you would run +X degrees or -X degrees of the original position on the cam.bringing this thread back up from the dead to discuss something that others might be interested in.
Question - for all intensive purposes, wouldn't shaving down the block 1.83mm have the same effect as using rods that are 1.83mm longer?
I'm sure i'll be told that I should just get the custom length rods, however, they aren't necessary for my application. I'm running low boost, but my combination of components raises compression too high and has made tuning the car difficult. I want to reduce compression, but not all the way down to 7.5:1.
I don't think its necessary to spend another $250 for rods I don't really need. I'm also not concerned about damaging the block and the inability to swap back to stock or other pistons - z6 blocks are cheap and disposable as far as I'm concerned. I also don't want to machine the head, as it has already been milled and I don't want to take it down any further.
Any reason why I shouldn't just deck the block by 1.5mm or so?

Is there any way to get a sense of how much the cam timing will be changed based on how much I shave the block?
Is not needed.
To be honest, even as a noob, I didnt ask questions. I got my ass on HMT (before Rick P's faggot ass), and searched my ass off. If I couldnt find it there, I googled it. If I could find the answer, I looked harder. Because guaranteed, some "noob" had asked the same stupid question that I wanted to ask, and a million people answered it.
And in the end, I turbo'd my first Honda, and with great success. And the shit that went wrong, I had enough common sense and mechanical ability to figure it out.
Noob or not, if you cant do that, or dont want to, you shouldnt be working on your car in the first place. Take it to a shop, and pay them to do it for you.
If you dont want to research, spend some money, do some trial and error, and blow some shit up. The information that is out there, is because someone else did this in the first place.
I cant believe, with how big of a trend the Vitara build is, people are still answering the stupid fucking questions, that these "noobs" are asking. The information is EVERYWHERE, in EVERY build, on EVERY forum. It cant be that hard to find.
But luckily for you, or whomever else, including myself, someone got tired of the retards, and finally just spoon fed everyone the answers, and compiled it all into one thread... Which, even if it gets stickied, someone will still start a new thread, asking questions about Vitara pistons and deck heights.
