    I would not rush out now to buy a bunch of expensive aeroquip fittings to make the perfect drain hose. The distance is short and bulky fittings take up space, reducing hose length and thus flex that you may need. Try to study some pictures or just copy what others have done and that has worked for your manifold, your turbo and your drain location. If draining to the pan drain, I would want a quick disconnect there for oil changes since I don't like pulling hoses off barbed fittings and putting them back on repeatedly since the hose loosens up and leaks.

    Usually end up smacking your knuckles on something yanking the hoses off as well.

    I already have the aeroequip 1/2 to 10an fittings and 10an hose. Also have the 10an Y and 45 degree fitting to go up to the engine bay for vent.

    It should be pretty straight forward. I just have to order the tap, drill bit, and handle.

    I'm going mock some diagrams up at work tomorrow and let you guys check them out before I go forward

    Sometimes it's easier to use a ratchet and a 12 point socket rather then a tap handle. The handles for the 1/2 tap are quite big.

    Good to know! Thank you

    On a side know and I know may be thinking to far ahead. But I'm really thinking the car will be solid after these couple adjustments.

    Excuse my ignorance but:

    The shop I bought my fittings from has race gas, $10.00/gal. And this may be a question more suited for a tuner, Zack. But I figured I'd start a discussion here as well.

    Are tunes made for a specific octane? For example, the highest pump gas I have available is 93. And e85 is about 30 miles from me.

    Do I have to have my tune revised if I want to mix race gas with 93 or run it straight? Say I wanted to run 20psi safely at the track but the car usually runs 93. But I purchase some race gas, could I run it and turn boost up?

    Would tune need to be revision for meth.

    I have AEM kit installed

    Race gas has the same energy content as pump gas so it should not significantly change the AFR. If your gas where you live has ethanol in it adding race gas will make it a tiny bit richer due to not having ethanol in it. A small water meth injection will also make it a tiny bit richer due the the added methanol but neither should require a retune.

    This is absolutely correct.

    Your tune is already mapped to the injector max; Therefore, You can increase boost to where you are at 650whp and the fuel will be close. Verify the afrs are correct and we can retune as necessary.

    I would suggest dyno revising the car so I can verify everything looks good at these higher levels.

    These posts might be misleading. Race gas can mean a lot of different things. MS109 is much different then street blaze 100 which is different than say C16. All are race fuels. But ms109 has a different stoich then streetblaze100. Therefore it takes more by volume like e85 then say street blaze 100. Running a mixture of ms109 could cause your WB to read lean, as it takes more by volume. Kinda like e85 requires like 30% more by volume. Race fuels are the same way, you need to know what your putting in your tank.

    So, be careful just tossing in "racegas". Also, C16 likes a mess load if timing, so you would be down on power tossing that in. Your safest bet is to mix street blaze 100 octane if your going to do anything. Its the closest to 93 octane stoich value.

    A lot more too it than what I had thought. Thanks for letting me know. I'll have to call the shop back and ask them what they specifically carry. $10/gal though I might not be using it frequently. I'll work on getting this meth kit dialed in.

    I wonder if I can get this car up and running in time for this event near me. Would be awesome to try the car out

    Running into some issues with this drain. I haven't tapped the drain bolt yet but got under the car to see how the lines would layout.

    Turbo sits so low that that with a 45 degree off the flange with clock at 6 angles the line slightly lower than the drain plug and creates a 'lump' in the center section of the tubing that faces upward slightly

    would be okay to run a 90 off of the flange? Not sure if it'll drain as easy with a 90 or not

    Thats why we suggested not to use an fittings :/

    The drain should slope gradually down the whole way.

    I tried and tried to make off the shelf fittings work and I ended up having to make a custom piece by cutting a 90 and welding it onto the flange.

    Yeah,

    I originally bought the AN fittings when I was to weld AN straight fitting to the Dip Stick tube until you guys steered me away from it.

    Now I'm trying to make use of my investment.

    From the looks of that,

    a 90 should work on mine. The hose will slope down after it. Is that JB?

    Yes journal bearing 6262. Technique Tuning manifold but all the cast bottom mounts seem to end up around the same spot.

    Try clocking at 5:00 to see if that helps.

    Do you mean 7?

    I think the SPA would work. Really wanted to use something other than rubber line, considering it is oil.

    But I would like to drive the car as well
