Make the centre section shorter and run the outer two cylinders into the end as you would do on a non log style... The centre two can be welded on an angle towards turbo flange...
This one has made 300 rwkw with ease..

The primeries are level with ports.. But the guy wanted a high mount...
having them come out and down about 30mm or so gives good clearance..
Also mounting flange on approx 45* angle keeps turbo off inner guard..
A T04Z 1.15 housing was used on this manifold....

Ooops...Lol I have changed the tigs plug since that shot....

To do a good log manifold takes heaps of work. All bends flow into the turbo.
Heres a better pic

the problem with bends on the center 4 runners is no one can cut the curve out of the 90* cause i already wanted that and curve out the the turbo flange i was going to do but it pushes turbo 2 far out and hits strut tower so i keep it in the extra 2-3cm and i got clearance or i got to put turbo on a 30* angle and get all to annoying.


anyone with a lathe can do it, so any engineering shop can do it, hell you can do it by hand with a grinder, wouldn't take more than an hour to do all 4.

you really should copy the two nice logs that have been posted in this thread, they are both very very nice designs.

In all honesty, the original design, its stuff like that giving log manifolds a bad name, and if your keeping it that way, you'd be better of modifying a stock cast manifold.

lol, we've had about 2 mechanics, 2 boilermakers, and every1 is saying, MIG and TIG is far better. It's so confusing!!

Any boilermaker/welder will tell you the TIG is Better, even myself.

TIG (tungsten inert gas) also known as GTAW (Gas tungsten Arc Welding)

MIG (Metal Inert Gas) also know as GMAW (Gas Metal Arc welding)

1 letter different, Worlds apart. You'll never get the same control on delicate or precision stuff.

Can be Migged, But I wouldnt If I were Paying for it.

This is when I first did mine. my car is still not going as it an ongoing project but i mig welded mine. Spatter will clean off, but if you prep the surface( i.e. remove mill scale ) and set your welder up right you can mig without spatter.
Trial and error mate, give it a go i say. Ya appreciate more when ya make it yourself.

Cheers Corey

It's a bit off topic but how much would a good welder make a year? I'd love to learn how to weld properly. you can make some pretty cool stuff.

Depends what you welding and where you are doing it.

Best way would be to get into high production welding (ie Flux Core, mig, innershield) as all you need is a weld test to get a start. A night course will get you up to speed and certified if you pass. A flux core welder in my company where I work will make $30 an hour casual, with paid lunches and overtime all work done to AS 1554 (structual code).

If you want to hone your skills, do a Tig night course and chase the pressure pipe ticket, AS 1796 it will require a lot of patience, robotic movements and practice, lots of it. A good TIG (GTAW) welder can make $150 000 a year if he's doing offshore pipes or on a rig doing spool pieces.
It requires a vertical and horizontal (2g and 5g) as they no longer do a 6g (45 degree butt) for a test piece unless they are using ASME codes, ie ASME 9.

Good money to be had, but only if your good!
