I just want to know if anyone makes a turbo manifold or manifold set for a single or twin turbo on a LS motor, I've looked for a few hours and can't find anything . I'm swapping an LS3 into my '82 and want to do a single turbo setup, so if that helps for a reference... Do any companies make this, or do you guys make your own? Anything helps, thanks

Stainless works makes forward facing headers. Obx might too

Thank you!

the tubing on those is entirely too large for most applications..

OBX makes a set. I made my own around 4 years ago which look similar to the OBX ones. You could have an issue with the brake booster with the OBX. Unsure since I have never bolted a set up. I know when I built mine I had to fish it around the booster so it wouldnt be touching.

My new car I am going to just do a flipped truck manifold and possibly a flipped LS4 on the drivers side.

Here are some photos of my old setup to give you an idea with forward facing headers. Not I had cut the rad support out only bc I was fitting a T6 flanged turbo.

I modified my engine bay some and have a tubular crossmember along with a steering rack instead of stock steering.... with that being said...

A stock 2010 Camaro manifold on the drivers side pointed down fits with out modding.
On the Passenger side I used a stock Truck manifold.

Then made a crossover pipe from drivers/passenger to the T-6 Flange on Passenger side.

Ended up like this...
Hope that helps,

Thanks... It's over in the LTX/LSX swap area

If you need more pictures shoot me a email

Do you know if the Stainless Works manifolds will have a clearance issue with the Brake booster, or would just a stock manifold from a truck or camaro be best for clearance.

The manifolds are best for power and fit.... they hold more heat in than the headers so more of the exhaust energy is put to the turbo wheel instead of loosing it out a thin metal header.
Plus the manifolds seal easy don't leak and are cheap. We keep several sets here just to fit on the LS swaps we do.
I run a PA Performance K member, coil over conversion and lower arms/manual rack.

Ok Thanks, I'll go with the OBX manifolds. I'm sure I can find someone locally to help me tweak the manifold if I have any issue with clearance.

plus they will keep velocity up. heat and velocity are key to spooling well. im going to be modifying a set of truck manifolds for a set of stock GN turbos. will be awesome

Yep... Exactly....

I'm using the 2010 Camaro manifolds on my 67 Chevelle wagon with a stock 4.8L and two stock GN turbo's...

My Camaro did have a GN engine in it for around 7 years... 10.32@133mph pump gas on Drag Radials

oh? copying Moran's setup as well?

Not sure who that is or what you mean by that?

Don't think anyone does stuff quite like I've done
It....

Never seen that car before.... But mine's a Wagon and done totally different..

He is using a GN style turbo... I just happend to have two laying around and I've been into the V6 stuff a long time and know how the stock one's (two) would act on a 4.8L
Just building it as a pro-tour style car Only looking for 5-600hp with instant response and fun to drive with good MPG.

RaverRacerX

its not THAT different. thats about what im looking for. im probably going to have roots blower like response out of mine im also using a treadstone mustang tt intercooler.. should work well. the article is actually wrong.. moran used 2 stock gn turbos. the 5557's wouldve been able to do more that 12 psi

i wanted to ask.. do you know of anyone that makes/made more modern compressor wheels for the tb0348?

im using the gn turbos because im going to follow that upgrade path.

I must say, after driving a 500whp roots blown ford Lightning truck, I have a new appreciation for throttle response. Roots blown or twin screws are plain nasty
