DGheaders Performance header: New design tri-y 2.0 2.4 2.6 g63b 4g64 g54b

[ragragtimetime]

RRTT's headers are old school. They are some beautifully made and finished headers but I doubt you'll be finding a set of those gems in a hurry...I share Brads observations on the new design headers. I would think having #1 exhaust runner being that much longer will force the engine to pull more torque from that cylinder (might make it sound like a WRX - could be a good or bad thing depending on your allegiances )

good eye geezer101....its a Doug Thorley TRI-Y HEADER

??? are these EQUAL TUBES ???
OH the humanity--- what???

[camoit]

are the pipes equal length, I hoped for something prettier I guess, but they look workable.

Wondering about pulse collisions with unequal lengths/

Well since 98% of the stock manifolds out there are cracked and have the same length pipes. I really don't think you need to worry about pulse collisions unless you are pushing 8000 RPM and the direction of flow is all one way. Also thats more important on the intake side because the fuel can fall out of suspension with a carb.

^^ yep

I Want one!
So did these get built and are available this time?
Thanks for following through guys, its been a looong process for sure!

I I think it has taken about 5 years to get them up and going. The paired port ones have had a totally new redesign now. So there much better fitting and looking.

I know this is a little old. But do you make turbo header for the 2.4 4g64 SOHC engine. Mighty max head.

I second this.. I would buy two if you made them..

I am looking for a stock one from down under right now.. Here is a photo of one I found on the board..
Starion Turbo Manifold.jpg

[geezer101]

The 2.0 SOHC G63B Starion manifolds aren't the only option but the alternatives aren't much better. Single cam Cordia turbo will work (notorious for cracking due to lean factory tune) or the manifold off a 2.0 DASH 12v turbo engine (better design manifold - split pulse) The whole engine is a near no brain swap - if you can find one. Much easier than a 4G63 twin cam (PLEASE DO NOT START THE "don't waste your time on a SOHC, blah, blah, etc..." TIRADE - this is minimal mod to retrofit alternative...) 83-87 Galant Cyclone turbo)

I have access to both a dash engine right now and a cordia engine.. As both of those are hard to find I would still buy two manifolds if they would make them, One for my truck and one for the wife's truck.. If something happens later on I don't want to be looking for another unicorn! They have the plates and the tools they are almost there just some elbow grease needed to have a end product..

I am not looking to make a 10 second truck I want to put taller gears in the rear end and have the power to not make it feel like a dog on the low end. Plus if I stick with the 8 valve head I have a non interference engine I don't have to worry about wrecking my investment with a timing misshap or broken belt. No reason why a 4g64 SOHC 8v should not be able to push 250 to 300 hp.

Great post SamuelRock !!!
Correct Me if My readings are in error -2'nd Gen sohc 4g64 s.e.f.i. mighty max-,
Comp ratio 8:5-1
Throttle Body 2 1/8 " (54 mm )
Exhaust 1 7/8 " (48 mm)
106 bhp (98 to the wheels)???


Hypothetically,
CR up by 1 point,
TB id increase to 2 7/8 "
Exhaust(cat back) 2 3/4 "
= 131bhp, 119 to the wheels
Net gain 20% over stock for the same undersquare design ?

I think our truck HP is 116 out the box..

I am thinking forged pistons and rods and 18# of boost from a 14B = 250 hp

Do a Dana 44 swap on the rear end with 2.72 gears and kick back on the highway near 30mpg!

I am in the process of getting my engine 2.6 G54B rebuilt in my 87 D50 Ram pickup. I purchased the Weber carb today with the fuel pump and regulator from carbs unlimited. Also new distributor plugs hoses and some other stuff from Rockauto. I would be interested in the $500 header when I get the engine back.

[geezer101]

Not sure if he's still making them...

[D100dave]

I will give him a call today to see if he is...

Hope this is not a dead thread yet... Cannot find a header anywhere for the 2.6ltr 4X4. Anyone have any idea? Yep, its been a while I have been on this site.

Looking for one as well.

Hi

New to the forum, however was able to find someone still making headers in 2024, for my 1985 2.6l MM 4x4 on the site.

DG headers is still making these. Fitment was perfect and Dominic was easy and responsive to work with dgheaders@rocketmail.com

see images of installed, don't mind the black coating that was me using boiled linseed oil, headers shipped raw mild steel.
