???it was stated many times is that lsa is a measurement of events and is irrelevant, but many times ive hear references between lsa and different engines ? is a 106 lsa for example the same as the 106 on a buick or vw engine?? will it affect the different engines the same?

I've done just about everything you can do to a car and have a good amount of experience, including motor builds, transmissions, axles, restorations, and conversions, BUT have VERY little experience with FI. I've read this entire thread and it's very informative, as I just got my first turbo car. Got a good deal on it since the motor was knocking.
These last few days have been a crash coarse for myself
I do tend to agree with engineermike on his theories, as it seems to make the most sense.
I'd appreciate any thoughts or opinions on my project.... I'm building an LQ4 that I just picked up and am trying to decide on a cam shaft. I have the STS rear turbo 60mm on an f-body. I want reliability, low-maintenance, and just for the sound, a cam that has some lope (but not too crazy). I'm only wanting around 520-540rw, which I know can easily be done. I'm not, by any means, going to push it to the limit. So what I am asking is, "What is an example of a 'small' cam on the market that still has some mild to medium lope to it?" I want to have most of my power at low RPM's as I don't want to rev it to the moon to get max power. I want full boost to kick in at low RPM as possible, but still "some" lope.
I was thinking somewhere in the neighborhood of 220/230 w/ .550-.580 lift at the most, on a 115/116LSA
Any thoughts or suggestions are welcome...thanks!

BTW, I'm using the stock 317 heads w/ Comp 918 springs, and LS6 intake. Also, I am planning to get the heads re-surfaced just to get them perfectly flat and sealed up good, and get some good piston rings, as well as hone the cylinders. Thats about as far as I want to go with the build. I don't want to throw 1000s of dollars into it like I've done in the past![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Would it be worthwhile to use the bigger return spring with the 60mm garrett turbo?
Thanks again!!!

That was a lot of good reading.
TDP, based on page 1 of this thread, the EPP cam sounds good. Also, dont waste your time decking the heads and replacing the rings on a low power turbo build. It will do just fine as is.
Im running a LS6 and man I miss that lope. Im also looking at replacing the cam before a 3 bar retune. I will report back with power numbers after ONLY changing the cam with the same boost levels.
