I noticed in the last picture you're dumping the coolant overflow tube straight down, then scrolled up and there isn't a coolant recovery tank. Any reason why?

otherwise looks good.

by not having a recovery/overflow tank you will constantly have to fill the radiator, and it's a good way to get air into your coolant system without.

[QUOTE=samnavy;143837]Lev, there are two popular WB02's that we usually recommend. The first is from Innovate Motorsports called the LC1. It goes for under $200 but does not include a gauge. What it does include is a really nice software package that you load onto your laptop. Since you really only need to monitor WB02 readings during tuning, driving around with a laptop on the passenger seat for an afternoon isn't that big of a deal.

Does the LC1 wideband need to be installed in the car at all times, or can you install it tune your car and then take it out to use in another car?

^That's not uncommon. There's nothing wrong with borrowing one either instead of buying your own. It's kind of a pain in the *** to wire in just to borrow one and use it once though. You'll want some sort of piggyback or standalone in the future anyways, so it's makes sense just to buy one and make it a permanent install.... that way, anytime you make any change to your system (bigger injectors, another PSI of boost) it's all ready to go for tuning.

Also if you're going to do that, you need an extra bung on your downpipe cause the stock NB02 will still be used.

They are fairly particular to their power source and grounding connections. Ask in the MS forum for where/how guys like to run their install.

MS needs full time wideband input in order for certain things to work right. You could put it in another car but you better make the wired connections with bullet connectors or something that you can easily unplug.

.
When I installed my catback a few months back I had to put a plug in an O2 bung cause as you know my car only has 1 O2. Can I use that bung?

By MS I assume you mean Megasqirt section?

Yes, MS=Megasqirt.

If you intend to replace the NB02 with a WB02 and use the WB02 to feed the engine computer, then you only need one bung cause you're replacing the stock one. If you are going to install the LC1 alongside the stocker, then you need a spare bung. It doesn't matter where in the exhaust it is (you could stick it on the muffler) as long as it's not too close to the turbo... I think 6" is generally as close as you want it.

Normally, as coolant get hot, it goes out the tube to the tank and the end is submerged in extra coolant in the tank. As the system gets cold, the coolant in the block/radiator contracts and sucks coolant back in from the tank. With no tank there, the system will suck back in air after it has purged coolant.
