I used a threaded fitting on the oil filter housing.

Whereabouts on the filter housing did you tap into. Reason I ask is you need to have it on the side where the oil comes back from the oil cooler AFTER being filtered.

hole at the base of the pipe

Note that this is the twin oil filter housing part from a 4bd1t.

Do you have 3" dump pipe going to a 2.5" exhaust?

I'm wondering whether to persevere trying to fit a 3" exhaust or go to 2.5" and make it easier to route.

Are you still happy with a 2.5" exhaust or would you go 3" if you were to do it again?

3" is better for EGT's and sounds great but is hard to find space for, is more expensive.
2 1/2 " is just as good power wise (IMO) but can be routed in the same place as standard.

Your call

You can do 3" or 2.5" through the wheel arch, depending on your tyre size and how much you care about the tyre scrubbing against it.
My stock exhaust scrubbed on 255/85's. My 2.5" will not because I made it. The 3" on my county does not scrub, running 235/85's.

This exhaust is 2.5" all the way.

My county has a 2.5" dump (180 deg mandrel bend from the turbo) into 3" system.

IMO the 2.5" sounds better, but it's also a different (and smaller) turbo.

Allegedly 2.5" is "too much" backpressure and 3" is "too little" and 2.75" is just right.

I will stick to 2.5" in the future.

Thanks for that, and the picture.

I originally planned for a 3" and to route it between the chassis rails to make room for another sill tank on the passenger side. The more I get into it, the more I'm having to compromise:

• It's going to be a lot easier and cheaper to go 2.5" through the wheel arch and down the side where my existing 2" NA exhaust is (can always put my water tank somewhere else)
• I initially thought I could mount the exhaust manifold upside down which gave better clearance for the compressor sprial and to route the inlet pipe under the air cleaner. But now I think I will just go over the top of the rocker cover and sort it out later.

This is a RFSV with a passanger side fuel 50L tank, no problem.

Attachment 158585

I have seen someone with a hx30 route the outlet like that with teh manifold right way up, (I did it the He221w). I had a go with a hx30 but I could not get clearance bewteen the elbow and the exhaust manifold.
Maybe someone who has done this could share a photo of what they cut out of the exhaust manifold?
You could space out the T3 flange and use that spacer to add an EGT gauge too.

My he221w is spaced off the T3 flange with t2 adapter.

Hey, that looks good. I will check on my vehicle. I have a 64l LRA fuel tank on the drivers side but current constraint for long trips is water. I'd still feel a bit uncomfortable with the exhaust more exposed on the side, but I've never dinged my current one.

Yeah, I considered a spacer. Was going to make something up, would only probably need about 5 - 10mm to get clearance I like the idea of having the probe there too. I think I'll mock-i up with a block of wood and see what fits best.

I tried spacing the turbo from the manifold T3 flange last night. A 5mm spacer is sufficient to get the compressor housing rotated enough. So I will make up a spacer out of plate.

I can't get enough clearance under the bonnet to have the pipe go over the rocker cover so the above is my only solution now.
