A Picture Book-my Tib Work-turbo-build
the high comp setup would be really great with a very good tune! though I'm not sure that the pistons could handle the heat, it would have been better with forged ones. but anyway, I like how you would go high-comp. it should compensate for the turbo lag everybody is complaining about AND give off a more linear and hence more driveable, traction friendly power-band. goodluck on the project!
just make sure you will always keep an eye on AFRs and EGTs. pinging can be a VERY big b**** smile.gif goodluck again!

haven't had much time to take pictures or work on the car but i have it further along than it looks more pictures to come.
don't have pictures of the following but is done
ic piping is done
head is taped for oil
oil pan is taped for turbo oil return
things that arnt hooked up include hoses for wg bov and boost controller, kinda confused on what goes to what.
i know boost controller goes one from the taped part of the turbo then dunno where the other end goes.
wg have no idea prolly the other end of the boost controller connects to it some how(there are two connecters for hose on wg)
bov i know one hose goes to vacuum don't know where other one goes.
lol some little but important details to sort out but will do my research.
The BOV is connected to your intake manifold/post TB, and your boost gauge is T'd off this line.
Also the BOV should only have one vacuum port?
Your boost controller is hooked up to top of wastegate; and the other side is T'd off wastegate reference bottom port and turbo port.

If someone can confirm this would be nice.

I see a broken ringland in your future. It's the weak point. Hyundai pistons are shit with stock 10.3 compression. And you raised it.
I also see you not wanting to settle with 200hp after ALL that work done. It's really not much of an improvement. Ask anyone with a turbo setup and they'll tell you the same. Everyone wants more.....
I honestly think you should go back with low comp Wisecos.

In my experience with at least the Beta 2 pistons, which are basically the same with just subtle tweaks, they can hold quite a bit of boost in a properly tuned engine. On my stock block I ran upwards of 20psi at the track and when I finally tore it down I saw no damage on the pistons.
Now increasing the compression can help if done right. The key is in the head modification and maximized your quench pad. If you do both of those and tune the heck out of it your high comp engine will last a long time. I would not go above 15psi with the high compression though.
