Thread: 3" Exhaust

I have the Isuzu truck engine and flywheel housing, and it has plenty of room for a 3" exhaust above the starter and down the firewall to the transmission tunnel.

Even with the higher starter position on the Land Rover flywheel housing, I'm surprised you can't do the same.

Unless you were willing to give up 33" tires and routed it out the side..

That's what I was actually getting at. I don't have a heater box there which I assume would be in the way for most people. On mine it looks like there is enough space, which seems like the least amount of exhaust routing if the turbo has the dump pipe facing backwards. It results in the exhaust dropping to the exact same spot as the NA exhaust on the inside of the chassis rail.

It's funny that JC's faces backwards, but then does a U-turn back in front of the starter... so not quite what I meant! I think isuzurover may have routed down the gap I was imagining...but with forward facing turbo dump.

(stolen from his budget turbo build thread)



Anyway, no matter. I've just had exhaust routing on my mind lately - as you do! I'll post some pics in my members ride thread and you'll see why.

You have a 3" mandrel bent exhaust? Exiting through the inner guard?

There are a couple of ways, but I find it easiest to use the gallery here.
- Click on the "Gallery" link at the top of the page
- Click "Upload photos"
- Choose your photos etc and upload
- Once uploaded - Go to your gallery, click on the photo you want and then copy the link from underneath it (there are different sorts of links but the bottom one give you the photo full size in your post).

Once you've got that link you can click on the "insert image" icon at the top of your post and paste the link in.
