What LS Exhaust Manifolds / Headers

I agree with Eric. What RH does is order the set from Sanderson in plain steel, have it delivered to their door, remove the sanderson name plate or any other evidence that it wasnt made by RH, have it coated and then send to the customer pawned-off as their own.

I bought a set from RH for my 944/LT1 conversion in 1997 which was missing the Sanderson name plate. Then I bought a set directly from Sanderson which had their plate on it. No biggie right? ....Well, actually, I paid $700 for the set from RH whereas I paid 250 for the set directly from Sanderson. Shady business practice. Live and learn though.

What is the part number for the sandersons that fit he 928? Their headers look very nice.

follow the link in my post. It will take you right to them

I have order a set of the Sanderson LS158.

I called RH and they said they do not make LS1 headers for the 928 because the factory F-Body Camaro LS1 manifolds fit and flow well enough for most applications. I waited for a week to see if a cheap pair would show up on eBay and opted for the headers instead.

Here is picture of the motor mounted. It felt good to see this progress ( the clutch input shaft lined up perfectly ). I test fit both the truck and corvette c5 manifolds. The truck manifolds almost work. The triangle flange on the driver's side manifold hits the steering column. I think if it would have been a 2 bolt flange it would have cleared it. The C5 manifolds hit the cross member the only way this would work is by cutting a pie slice out of them to turn up the down pipe, not worth it IMHO.

Forgot to follow up with a picture. Sanderson Headers fit perfectly.

Now it is on to the plumbing for fuel, coolant, and power steering

I have not found the right headers but it looks like you did the homework for me. Can you show a picture from below? I am still working on the details on the engine harness and running plumbing. I used a 5.3 truck motor, Z06 cam and valve train, used a alt/p/s bracket made by dirty dingo so the alt would clear the hood. My engine is rotating but have not flashed the pcm or installed the fuel rail.

Just call Sanderson, they have a set that fits perfectly. I've used them on three cars so far with no issues.
LS1 headers
They also make them in 1 5/8" as well as 1 1/2"
No these won't fit the 944's so don't ask.

I bought the ls158 from Sanderson. Credit is to Admin as the one who pointed me in the right direction. Sounds like we are doing very similar swaps. I am not going to cam my 5.3 until after I get everything working, trying to keep my costs focused on the essentials as I am on a tight budget.

What year is your 928? Where are you mounting your remote oil filter?

located on the frame rail right by the p/s pump. short run to oil outlets on engine and easy access to service. Mine is a1987 928s4. I'm a camero fuel rail and a vette fuel filter with a short return to the fuel tank from the filter.

ps. mounted adapter side ways with the filter facing the radiator to protect the filter from any flying objects under the car. Later I plan to put a belly pan underneath don,t want anthing sticking down.

What accessory bracket are you guys running?

Rob,
The F body brackets work just like the 944's

Does the GM PS pump have to be modded for the 928 PS rack?

Also to confirm, does the Sanderson LS134's have the O2 sensors built in?

And does anyone have a picture/dimension of the rear driver's side head to firewall clearance?
I would like to set the drivetrain back another 1.0" to get more CV clearance when I mount the 6-speed.

I used a aluminum bracket from a company called Dirty Dingo
The pump works fine. Steering is a little stiff but better than too loose.

That 928 looks so cool like that.

As far as the PS goes I thought someone said that there is a GM power steering unit that the Porsche 928 lines would bolt right up to. Anyone know which PS unit that is. Are you thinking about retaining the original 928 PS reservoir?

I plan on using the F body accessory brackets. Did anyone have to have special hoses manufactured to retain the original Behr radiator?

Thanks,
Aaron

I used the 2004 silverado pump and brackets except for the alt and p/s pump bracket that I bought from dirty dingo so the alt would clear the hood. The lines for ac and ps I took the Porsche lines and the gm lines to a shop that make up pressure line and had them cut and splice. Worked nicely. This set up put the ac compressor right by the Porsche ac lines for easy plumbing. I'm up and driving now but haven't finished the details on the ac. Don't expect any problems.

I used 2002 FBody Headers on my 928 conversion. They cleared just fine.

Were those the OE or after-market headers?

LS1 Fbody Headers (From a 2002 Camaro SS in my case) worked just fine.
