No, it cannot be done easily and when you want to install the 1.5 GTM SC kit air intake tube and filter, it is so much easier when the exhaust manifold is removed.

Tip: you don't have to remove the catalytic convertor when removing the exhaust manifold. Remove it from the engine compartment from the bottom.

Did it, I forgot how much I can't stand exhaust work. Hope I have no leaks. All I have left is the Alt/PS assy, and some fab work, NISMO to Zspeed undertray mods.

Thanks

You will need to separate the cat from the manifold b/c it is easier to install the intake pipe then the air cleaner then the exhaust manifold then the cat,the reason is it's a bitch to line up the air filter with the exhaust manifold and cat already in the car.

Next question, (this will never end) after some research on BOV's, it looks like we should be closed at idle. My valve will not a-just to closed, Turbosmart sells higher rate springs.

The only thing this should change is the hiss at idle and a small chance of intake charge contamination.

In the GTM 1.0 you recycle the BOV air but in the 1.5 and 2.0 it is open. If you through a belt you would sucking in unfiltered air. I am going to put a small K&N on my valve and get the correct spring to close at idle.

Nope they will be open at idle,you can adjust it alittle tighter so your boost/throttle response won't be lost.

The bypass valve needs to be open at idle since the throttles are closed (high vacuum in the manifold) and the supercharger is trying to force more air into the engine. The bypass valve operates on a pressure differential between the charge pipe and the manifold. The higher the differential pressure, the more the valve will open. It is operating correctly. Also, if the belt were to fail, the supercharger would stop turning and therefore would no longer be pressurizing the charge pipe, the pressure differential between the intake manifold and the charge pipe would be less than the spring pressure in the bypass valve and the valve will stay closed.

Putting a stiffer spring in the bypass valve will cause compressor surge since the charger would be trying to move a small amount of air at very high pressure ratios. Bad idea.

The reason why a blow off valve on a turbo is closed at idle is simply due to the fact that at such low exhaust gas flow, the turbocharger is not spinning fast enough to even generate positive boost pressure at idle.
