see that is counter productive.
1. I already have this manifold and it works fine. Also the EGR runner is a great place for the EGT sensor.
2. a gasser manifold may be better...but boost is boost. Just because cylinder 2/3 are favored...does not mean equal boost is not being distributed and in the grand scheme of things...this is an old POS 1.5.
3. Imagine there is 10psi in an intake, when cylinder 1 intake valve opens...gets all the boost, and so on and so on.
A gasser manifold may be the optimum situation but I think a TDI manifold will be easier, cheaper, and won't make me cut a perfect exhaust manifold that will require nickel welding since it's cast.
lol, you seem like you need NO HELP at all. you must have built a few of these already?
ive been there, done that.. got the tee-shirt. the gasser intake is a great upgrade. makes more torque on the bottom end. keeps cylinders 1 & 4 from getting too hot also. again, been there, done that. ive blown up a 1.5 from boost. and the intake manifold had a bit to do with it blowing up.
you can weld cast iron with mild steel wire. i did on my VNT turbo, cut the EGR port off, welded it closed, then drilled and tapped my welding for an EGT probe. its not a straight shot into the manifold thru the EGR port.. but if you hack most of it off, it makes placing the probe much easier. lol, should tell my turbo manifold that it needs to be welded with nickel rod.. cause it got welded with mild steel wire from a millermatic 250, and its been holding up great for years..
trust me, just because the intake has a box style plenum, does not mean it distributes the air evenly. there have been counltess threads about how the TD manifolds suck because they bias the center cylinders soo bad.. cyls 1 & 4 DO GET HOTTER then the center cylinders. the 1.5 i boosted, you could see that the outter pistons were more eroded than the center pistons.. that manifold does make a difference in air flow.
anyways, they were just suggestions, do it how you want, its your engine. i just know that i would be using a gasser intake because it makes things soo much easier. plus, it looks cool. and it works way better. you can feel the difference, just from replacing the intake manifold. and another thing, the RIGHT ANGLE ports on the intake manifold, they flow like hell..
also, you want the EGT probe in the stream of exhaust gasses, not up in a port like how you would install it in the EGR port.. so more than likely, even if you do put the probe in that port, its probably not going to read the correct temperature, its probably gonna read colder than it actually is..
either way tho, its your build, im not gonna twist your arm and make you build yours like i built mine, although you would thank me for twisting it after you got it finished and noticed the difference! lol..
