It def is really easy. Install a MAP sensor and make the switch.

The car is running pretty good now. I got the new full length SS braided clutch line put in and all I have to say is this has to be the best 40 bucks I've spent on this car, it's never shifted this easy and disengaged this well, I def recommend this piece. I also got the FP intake pipe installed and man that thing makes my car sound way meaner than it actually is, and the BOV sounds pretty good too. I have a question about the BOV too, probably an easy one, but the BOV shouldn't leak while the car is just idling right? I can feel air coming out from the BOV while the car is just idling. Oh and the tach decided to stop working tonight too,so there's another project. But anyway I snapped a blurry, grainy photo of how the engine bay looks right now. Don't mind how messy it looks, I always have the motivation to install new parts but I usually run out of steam when it comes to the "making it look good" part....

It's leaking because your car is probably making more vacume than the spring is rated for. Someone correct me if I'm wrong here. The sple purpose of the spring in a bov is to hold ot closed when not in boost. If the spring is weaker than the amount of vacume your car is making then it will pull open the valve slightly. Is it adjustable? I can't see what brand you have in the photo.
Might just be the picture but, are you missing some manifold to turbo bolts? looks like there's only two of them...

Some cars that have a high vacuum at idle have been known to pull the diaphragm open on the BOV. So, not all of them do it, but it's normal for some. How much vac do you pull at idle? With my Kelfords, I only pull 12 in/hg and my GReddys don't open at all. But on stock cams, I pulled 22 in/hg and IIRC, my BOV did open a bit at idle.

I'm running a stock 1G BOV and I haven't modified it at all, I'm not sure if the previous owner has done anything to it or not. At idle I pull about 16-17 in/hg according to my MAP sensor, I'm on Comp cams 101200's so that's probably why the numbers aren't in the 20's.
And yea, there's only 2 bolts, the other two are broken in the housing and I just haven't had the motivation to fix it, there's a pretty thick gasket there so it doesn't leak, or at least I can't feel anything while idling I'm sure it's a different story while I'm getting on it.

Don't have much experience with the stockers, maybe crushing it slightly to preload the spring would help this issue? There's only one other mod that I'm aware of, but I don't think it would help this issue.

When I was running a crushed 1g BOV at idle you could hear it leak a little bit, whether or not air was coming out I couldn't tell because I was running recirc...try crushing it, because your vacuum was lower than mine it most likely will not leak (as much)

Plus if crushing it doesn't fix the problem, or you crush it too far and would like to go back to an uncrused one instead of upgrading, I have a couple uncrushed ones laying around that aren't worth much.

Hmmmm alright, I might just pick up a new one since they're only around 100 bucks anyway. I've got another question, you guys that have wideband O2's how much do your reading bounce around while cruising? My readings stay around the same number but bounce around about a point either side of the reading (it doesn't just settle on one number). I'm thinking it's either because I might be leaking exhaust out where the manifold meets the turbo or just because I have it in the stock O2 location.

My wideband bounces between about 14.6/7 and 15.x. it's normal since your car doesn't stay at one afr while cruising; its shooting for a good average. So you will get a little high and a little low.

Thanks to laser92 I picked up another 1G intake manifold and took it to work today to drill and tap it for two extra boost sources. I also had some Loctite aluminum putty laying around so I slathered some of that on the two fittings. The only thing I'm worried about is the putty says after it cures it's good for 200F, anyone know what sort of temps the intake manifold can reach?

New intake color... Dupli-color high temp with ceramic black and clear coat, turned out alright I guess...
