I've kept it kind of on the low up until now, but I recently (finished totally today) installed a super16g on my car, w/ tubular manifold.. Check out my garage for pics and what not on that:

But... ever since the install I've had hella problems...

#1, the manifold (I believe it was a prototype KOU manifold) isn't aligned perfectly, so everything is crooked, all the oil lines had to be fabricated, and new fans had to be perchased.. Luckily all these problems appear to be fixed with some serious help from Carl Crawford (Owner of Speed-Source). Can't express how helpful he was with the installation and letting me use his shop + lift to do it.

#2, this manifold gives off some serious heat.. On top of that, it puts the flange where the manifold mats to the turbo about 3 cm from one of my new fans.. I'm afraid it's going to melt, I've already smelled burning plastic when stepping out of the car, and that hasnt even been during serious driving... The only ways I can think to fix this problem are:
a. Thermal wrap, but I'm afraid the manifold will crack...
b. Heat sheild (at least in front of part of the fan), this seems like the best solution, but there really isnt much room to work with there... and two it will block some airflow..
c. Put the factory manifold back on, but this would mean im stuck with a tubular manifold and O2 housing, and plus i would need to purchase a HRC O2 housing..

#3, I'm having boost problems... I'm thinking it is because I am still running the stock downpipe and just having serious boost creep.. I have the AVCR set at .65 bar.. I would assume that is somewhere near 10psi or less.. Actually, I'm not even sure this wastegate will allow for any less then that, but none-the-less, the turbo should not be seeing levels of 16 psi when its set that low... Tomorrow I'm going to bypass the controller, and just route a line from the wastegate to the turbo for now, just to see what the minimum boost is, and to keep things under control until i can get this thing properly tuned.

#4, I cant tune this thing, i dont have a datalogger or cable..

Other then that, seems to run good, I'm just freaking out

was the manifold portmatched to the 16g? If not, expect some lag.

Yep it matches up, I'm pretty positive its the downpipe now that nate supports the idea, the O2 housing is like 2.5 and the stock pipe is like 2

GSXracer, if u can pm me the number of winners circle and some info about them/the ceramic coating that would be awesome... thanks

In my experience the opposite happends. I have very low boost with excelent control before upgrading my exhaust. The second my 3" downpipe went on my boost shot up.

You said you have a super 16g. Don't those have a 15psi spring in the wastegate actuator? I'm assuming you are talking an HRC super 16g.
