Hey all,

Having issues with fitting a 3" downpipe on a RHD car. 666fab manifold and 18cm2 holset rear. Anyone with a RHD and 3" DP, please help ?

marc at dirte30.com to send pics, or post them up here.

*looking at fozzy/ant.etc ;)*

How much was your holset manifold from 666?

This is what the downpipe looked on my 2.8

Nice Gunni, very nice!

From what I have gathered 5 and 6 pipes coming from the ports need to bend very soon so that a downpipe actually get´s past there.

Wish I had never used that log and just built a manifold

Why?

Not pretty, but functional.

Because the time it took to modify that one I could have just made a tubular one.

Hmmm, I'm not sure I can get a 3" bend back under the manifold to run that side of the steering knuckle.

I'm looking at ripping out the steering couple and using a solid spacer instead to get some more room.

Thanks guys - any more photos appreciated!

The bends I used are extreme angle, i.e their radius is a little to tight to not interupt the max flow capacity of the pipe size.

I've some pictures somewhere.....but it's pretty much running down the bulkhead behind the steering linkage. My number 6 runner hangs out quite a bit and it forced the DP towards the block, then a 20' bend takes it back towards the oem exhaust position.

My turbo sits around cyl 2,3, further forward and I would have routed the downpipe around the steering at a lesser overall angle, like what Toby did on his M30, I don't like the 90' bend a foot from the turbo, just doesn't look/feel right for some reason.

I'm going to 3.5 or 4 inch to the steering linkage this time, leave the rest at 3 inch, only because I'm redoing the turbo position so a new one has to be made anyway.

Pics of the problem area????

have a look at the link below

The two joined pipes on the left in the V are now gone (relocated to other side) they are wastegate pipes. As you can see I cut some heatshield off the firewall, still can't fit 3" down there without touching everything

You need to take #6 off and raise it´s exit from the manifold.

Do you have pictures from the other side where #6 joins the manifold?

Here ya go



Two turbos, RHD and there's another 2" wastegate pipe to go in too

Thanks all. I'm going to fit an E36 rack with one of Dan's splined shafts. Should give me plenty of room.

that's a good idea does the e36 rack fit?

Yep, check the Group Buy section for the thread "Steering Linkages" started by DanThe and have a look at his comparison picture on the angle of the steering knuckle between E30 and E36 rack... I think it's on page 5.

There are a couple of pics of my twin turbo set up here. Drop me a PM if you want and i will dig out the CD of the build and send you some better pics if you need any.
