Does this look right? (pics inside)

[kilcourse64]

I believe I have everything routed correctly, but to be on the safe side I wanted some opinions from experienced SR owners. The nipple on the right of the intake manifold (larger of the two) goes to the BOV, while the nipple on the left (smaller of the two) splits between the FPR and boost gauge. The bottom nipple is blocked off.

Also, I was a bit worried that I tapped my hotpipe too far from the turbo, opinions? The boost controller is from DNA Motorsports, opinions? Has anyone heard anything about the wastegates on the Isis T25/T28 turbo?

Thanks in advance

Looks good...

Just make sure your BOV has a vac/boost source(i.e. nipple located behind the throttle plate), otherwise it won't function correctly. Everything else is just as Flip said.

The vacuum line to your boost gauge from the fpr, looks suspect as hell!

Any advice on how to make it less suspect? The hose provides a snug fit on the T from the FPR and I secured it with zip-ties as well. The boost readings are dead-on consistent, but I'm all ears if you have some advice.

Generally looked down upon to t into the fpr. Have a dedicated line for only it.

The best fix, would be to remove the nylon line and the fitting on the gauge. Replace it with a nipple and silicone hose, 3mm or 4mm

If not use a plastic weld kit, weld the nylon line to the plastic T.
I know for sure that line is leaking, but will it pop off IDK

Teeing to the fpr is fine, why when that line pops off or leaks you should know by looking at your boost gauge. Being that you connected it like you did, you should be constantly monitoring your boost gauge anyway!

Yeah, this is just one of the things we need to stop!

Squash nut on your wastegate rod needs to be tightened. It should butt up against the adjustable end, tight. Looks to be an adjustable wastegate. You may want to dial in the boost with the WG, close to what you want to run daily. Then fine tune the boost level with the MBC.

The nylon line fits very snuggly in the vacuum line, the fit is actually so tight that I'm worried the diameter of the vacuum line may be too small. I was trying to avoid what you mentioned, a leak, so I may have gone a little overboard in my pursuit to prevent it.

I'm running out in a few minutes so I will most definitely be looking into a nipple/silicone hose setup, as that would be ideal like you mentioned, but I'm still confused on how I would avoid T'ing off the FPR since I am using the other nipple on the intake manifold as a vacuum source for the BOV. There is the lower nipple that I have blocked off, but that is before the throttle plate, any advice?

I should have been clearer when I posted this picture, but yes I am aware, the nut isn't locked down because I was setting the wastegate to the correct amount of boost that I am tuned for (as you can see it's a pretty conservative setup). I plan on perfecting the setting with the MBC like you mentioned.

If you're going to T something off, T off the bigger vacuum source. Aka use the bigger port for BOV/Boost Gauge. The smaller FPR source needs to be a direct connect, no T'ing off.

[Lutz Performance]

yes FPR needs to be on its own source

the T boost gauge, bov, wastegate act

The fpr doesn't need to be on it's own source, even the factory routing has it tee'd!
If it's tee'd with a pressure gauge you will know when there's a leak!
I know for a fact if you search this issue, the same people say the same shyt over and over again. Then every once in a while someone lame will agree with someone!

All I'm every trying to do is get, all of the half broken 240sx's running!
I should make a list of all the misconceptions running rampant in the community!
Vacuum is vacuum, boost is boost, we have gauges for a reason install them so they work!

To avoid the Teeing, get or build a vacuum block, but it's not necessary! you are fine teeing the fpr!
I use all the stock nipples,
left top, fpr/boost gauge
right top, BOV
bottom: boost controller
I have a gt2871r/ w T04E cover, it has a nipple for my boost source, external gate.

Thank you, I appreciate the explanation, sounds logical.
