Hello All, we were doing a tech piece on a mockup engine in the shop and took some photos of how things fit together with our new divided Cast Stainless manifold. The Turbo is our 79mm T4 SUM-270004R. The manifold accepts our 44mm diaphragm gate SUM-260072 or the high-end piston style SUM-270100R. We took pics of both so you could see how they fit next to the downpipe.

We used a length of our 4' Stainless tubing with our Downpipe Flange Adapter SUM-260803

The plug wires need to have 90 degree boots on the spark plug end. If you guys have a part number that works well for you, please let us know and we can add it to suggested items. Crusty old truck coils were used in the photo because that's what a lot of guys run.

So here for your viewing pleasure! Please let us know if you have further questions.

Msd makes a short and long plug wires, and have plug ends you can bend. The round truck coils take the short wires, the ret. ones use the longer wires. Looks like the short ones would clear. Be interesting how that setup would fit in my G body, right now I have the Hooker setup mocked up.

Looks sharp Brian!

Might work decent in a G-Body.

Will the SUM-270100R attach directly to the same flange as the tial 44mm? If so I'm sold.

Curious to know if anyone try these yet "sum-260072"?
I know what they look like but unsure if Summit does anything to make them better other than engraving their name on?

The trick used to be a use an Accel short spark plug. Not sure if they make those for a LS engine. And your coil packs look nasty.

Summitracing

yep. Completely unique. We paid for tooling.

Summitracing

Ha ha yes. We went home for lunch and grabbed those out of the garage. We have tons of shiny new performance coils but not shaped quite like truck coils.

Summitracing

Yes. Identical mounting.

Summitracing

Let us know. We can help out. Although these are Modeled, patterned, cast and really the best out of anything; we are always looking for constructive criticism (rather than deconstructive criticism). Constructive is how we make stuff better.

Looks good! Just to clarify, your descriptions states "Divided log with 50mm wastegate mount for each bank of the engine." but you link to 44mm and 45mm gates. Assume the description is incorrect?

Any idea if this manifold will clear a high mount a/c compressor?

Quito195

No they mean 44/45 gate. I already got burned by their description since I had 2 50mm gates laying around so I bought one of these manifolds. The OD of the vband flange is 50mm and I’m sure whoever wrote the description doesn’t understand how gate sizing works.

Summitracing

Slow Sedan is correct about 44 or 45 gate is max. We will correct the description.

The Turbosmart 45mm gate fits perfectly on the WG flanges.





There needs to be some pictures of the manifold mounted to an engine in actual cars.

I think getting a 4" downpipes will be very difficult in the space between the firewall, block, frame, and manifold.

Pfff, just take the exit out through the hood like all the cool kids do.

​​​​​​If I was 22 years old, I would. But the last thing I want to do is cut a hole in my GTO hood.

Summitracing

. Yes. We are getting this fixed. Thanks for the spot!

We do not know at this time. We are looking forward to seeing the installations and performances in-car
