I wonder every time I see those bungs on the oil filter housing I wonder if I could use them to plumb in an oil cooler. For your rear mount turbos I agree with mikellucci. Keep it seprate.

 

Gotcha! I was just wondering since I had never paid attention to these bungs before. I'm still going to be running the external oil system. I would rather blow the turbos than blow my motor anyday.

 

Now that I know these bungs are here, I'll eventually add an oil cooler. I drive my car really aggressive specially when I track so this is a must!

 

Some new updates! Coming along nicely!!

 

Is there a particular oiling system you are trying to mimic out there in use? Would be curious to see it; got links?

Glad to see some progress!

Keep in mind, my complete turbo build took 5.5yrs! Patience is key; do it right the first time, or you'll pay for it in the end.

 

It's going to be a long night again...

 

The way we mounted the turbos ended up being perfect because the oil feed line fittings are on the top and the oil return fittings are facing down so gravity will help move the oil downward. The oil pump will go connected to the oil return lines so it can suck the oil and pump it back into the oil tank. I believe one of the other guys or may have been you... mentioned that it's best if I connect the pump after the oil return rather than before. Plus that's how some of the vette and gto guys are running their setup.

 

Can't wait to see the final product and the performance gains.

 

Great to hear that this build is finally progressing nicely after that long wait you had with the shop.

 

Thanks guys for all the motivation and useful information that you've provided during this build! It was a long night and I'm running on a couple hrs of sleep but today is the day she'll be started up! I'm off to Home Depot to pick up some oil return line fittings and then I'm back to the shop to get the oil system connected. I still need to find some intake filter covers because they sit really close to the rear tires. Bov flange will also be welded on today. I'm still missing some vacuum lines.

Any suggestions on where I can tap a line into to run a boost gauge?

 

Good to see this progressing! You could tap a boost gauge off one of the turbo compressor housings. I might shy away from doing that unless there's a clear path to run the vacuum line to wherever you're mounting the pressure sensor and ultimately feeding the wires into your cabin.

Otherwise, remove your TB and tap a barb a few inches before the intake manifold.

If you get into a pinch you can T your gauge off of the stock vacuum press/evap near the TB/intake manifold. I would not recommend this long term but for a few days and just the boost gauge it should be OK.

 

I'll have to tap into the intake manifold because otherwise it's a really long hose from one of the turbos all the way into the cabin. I need to go pick up a boost gauge today as I have no idea what kind of boost levels I'll be getting.

Quick question... A far as fuel goes, we only have crappy 91 octane here in Cali. E85 is easily available though. I see some of my friends running a couple gallons of e85 and the rest 91 octane in their 335's, evos, subi's, etc... Do you recommend I do that as well?

 

A few more pics...

 

^The best source is the turbo itself, like what was previously mentioned; but if you're not wanting to run such a long vacuum line into the cabin, then a source from the intake manifold is second best.

BIG NO on the E85, in this case. Our ECUs cannot compensate for the ethanol content. I boosted my Civic on e85, so I'm well familiar with it and what you have to do in order to run it PROPERLY. Sucks not having 93 octane fuel; I've got 93 & e85 at nearly all pumps in town here. E85 does have awesome properties though; the biggest being the added octane it provides. It helps prevent detonation, like race fuel. But the drawback to running e85 is that you have to run nearly 20-35% more fuel through the motor vs petro. So fuel mileage is not nearly as good. This is one reason why people say to try to find a gas station with ethanol-free fuel.

Sounds like a lot of progress! Wishing you well on the buttoning up all the minor things.

Oh, btw...I don't recommend running cheap air filters on those turbos!

 

Thanks for the e85 lesson. I wont't be running that for sure!

I reference to the boost gauge line... I have no problem buying a hose that long and running it to the cabin but won't that give me an inaccurate reading due to how far the turbos are in the back as opposed to running it directly off the throttle body?

As far as the intake goes... I ordered some k&n intakes with a 2" opening but they haven't arrived yet. For now this is my second best option.
