CA and TB time
Alright, on the advice of a certain mod, I'm going to consolidate my rants and raves into one thread, sticking with my original post about mt TB and CAs. I haven't even started on the CAs yet, I'll get to that.
While I had the car all pulled apart, I decided to change my intake mani gasket with the NewSouthPerformance gasket that is supposed to help lower intake temps but about 20*. In the process, I cracked a plastic piece on the back of the head through which coolant flows. Needless to say, my attempt to repair with epoxy and a hose clamp was an epic failure, and after a quick test drive, it leaked, I overheated, and I'm in need of more G12. I found the part on ECStuning, only 20 bucks, no big deal, and not too much of a headache to get back in there and replace it.
All that to get to my real question. Something happens once I hit 10 PSI, the car seems to bog down a little, make some wierd noise, almost like a boost leak, and won't build any more boost. I don't think it's a boost leak though, I only removed one line (DV to intake mani) while doing the TB. It runs fine as long as I keep the boost under 10.
Also, and maybe it's my imagination, but at idle, or coasting, my vacuum is 20 in Mg, and I could have sworn it was closer to 25 in Mg before.
Any input or troubleshooting advice would be great, but naturally, I won't be driving the car until I get my coolant leak fixed. Overall, the TB job wasn't too bad, and one hell of a learning experience. I managed to do the entire job myself without any extra hands, and the blauparts tool kit was rather helpful, but wouldn't have been required if I hadn't done the seals as well. I'm sure I would be able to do the entire process again fairly quickly, and I don't regret doing the work myself at all!

Yeah the coolant flange. Nice! Be extra, extra sure that the new O ring for it lines up perfectly when you install it.
Didnt' you have to remove a couple vac lines on the intake manifold to do the gasket? Sounds to me like you either forgot to reconnect a line on the manifold, or maybe created a leak in one of them in the process. A leak at the intake manifold would explain a drop in vaccum and boost. 20hg is about normal with the AC off, but if you are used to 25hg, then ya.
