Where?

Re: Forward swept turbo headers

What about these? They are 1 5/8 ID log style manifolds. Certainly flow much better than stock (not as well as headers) and route forward for conecting to a turbo. Piping is schedule 80 - so they should stand up to most any abuse. Have them coated to reduce temp. All for less than $300.

are those for 3.8 camaros? If so thats awesome, not as well flowing as headers of course but who cares that's a steal.

Re: Forward swept turbo headers

I built them myself... Schedule 80 pipe, a 3/8 flange, and a mig. The cost of the pipe was just under $200 - I wouldn't have believed the expense of this stuff if I hadn't seen it myself. The swain coating will run $100 - $150 and is a true ceramic (thick) thermal coating - not just a jet hot dress up.

These are sitting on a 3.4. I posted a while ago about forward swept headers and noone had any good leads (beside fff). I did not have room to fit the fff ones so I built them myself. I am building an Opel GT with the 3.4 as motorvation and if you know what an Opel GT is you know there is VERY little room - which is why I chose the 60 degree v6 motor. The forward swept exhaust was a necessity as I could not exit the exhaust by the rear of the block for clearance reasons. Now, since I have the forward exhaust, and there is plenty of room in front of the engine, it would be silly not to do a turbo (at least that's what I tell my wife). I got the idea from a friend of mine that builds custom engines - mostly 4 cylinder turbo Opel engines. He has used these materials for some time and has never had a problem.

I am presently half way through another set and these new ones run three pipes into one collector - like true headers - only not equal length. They still exit in the front. I havn't decided on a three bolt flange or a ball joint yet - but as soon as I do they are off to get coated. From the picture viper04af posted - they look to be the same design as the new ones I am making.

we us the Vband flanges...... easy, simple, flow well

Re: Forward swept turbo headers

I have looked into vbands... I am not sure if I should use the 'kit' and weld on the flanges, or get the pipe with the flanges already welded on. I know that many turbo applications use vbands - so I suppose they seal well. Both the three bolt and ball flange are cheaper than vbands. Is the selling point the sealing power?

Three bolt flanges would certainly be the cheapest - but if the exhaust pipe joint is not perfect, they will not seal well.

The local exhaust shop can do the ball joints at a reasonable cost. Ball joints seal better than three bolt flanges and allow for a little wiggle room.

Re: Forward swept turbo headers

Good luck with your GT! Had a 70 1.9 with sd weber ,cam,headders and ff exhaust.I had great fun with that car in my younger daze,wish I still had it. BTW the sway bars and rearend [3.44 ?] from a kaddet will fit the GT.

Re: Forward swept turbo headers

Thanks Puffadder... Mine is a 70 and originally came with the 1.9. It now has a complete tube frame with a mustang rear on ladderbar/coilovers. the front is mustang II with r&p. I have 11 inch vented discs all around. The car weighs less than 2000 lbs so I am only looking for 250 ish hp to make it scoot real well. The turbo I am looking at is a Garrett super60 with comp 60 trim .42 a/r and turbine 68 trim .48 a/r. I think I am going to redo the manifolds once again and go with 1.38 ID to better match the exhaust ports. I think any bigger than that and there will be too much volume and lag the turbo.

There seems to be quite a bit of interrest in forward swept headers for the 3.4 and 3.8. Anyone want to talk about specs to see if this can become a reality? Tube size? How should the manifolds exit? With straight, 45 degree or 90 degree turndown near the front of the engine?

Re: Forward swept turbo headers

That's for the 3.8... would there be any difference for the 3.4? The kit that fff once made connected to the existing exhaust I believe (?) then routed it forward to the turbo and then back to the existing cat.
