w00ts '83 944LS1 Hybrid

In my case (in-progress 928 swap), I re-used both the OEM Porsche roll-over check valve and the pressure relief valve.  I kept the roll-over valve in the stock location, but shortened the line between it and the pressure relief quite a bit.  I was also able to place my Corvette fuel filter in the stock Porsche location. I relocated the relief valve because the OE set-up had mounted it above the rear bumper support using about three feet of vent line.  I just moved it near the roll-over valve and kept it in the driver's rear fender area with the fuel filter and other parts of the vent system.

One thing I did check was the pressures on the vent valve.  If a vent valve isn't working correctly there are a couple of possible problems.  The first is that the gas tank can pressurize trapping excess pressure in the tank.  The other problem, and the one that seems to cause the most problems for 928 owners (no idea about the 944 situation) is that the valve can malfunction cause excess vacuum inside the tank, which can damage the tank by collapsing it inwards and flexing it repeatedly over time until it cracks.  The pressure check valve should prevent the free flow of air in both directions, but open in both directions with only a tiny bit of vacuum or pressure.  I think my valve tested at 1 or 2 psi in one direction and 3 the other.

I absolutely love what you have done.
I did notice one thing on your exhaust manifolds.
I also initially wrapped mine and was promptly advised by Admin to remove it.
Apparently, even with the high heat ceramic coating they are very prone to corrosion.
Other than that it looks great.
Cheers!

Lookin' good.

On my swap I left the 944 fuel vent system including the carbon canister, deleting only the steel vacuum regulator and running the line into the intake before the MAF.

Erioshi:
Thanks for your input, i plan on cutting my vent line and using the WS6 unit mounted behind the bumper, will double check flow and replace with new if necessary.

RS Technic:
I appreciate the vote of confidence! Im Only trying to take the information provided and do the best i can with it! Call me a Spleen i spose lol. My concern with heat under the hood outweighs my concern about rusting/gone mani's. I mean, what kinda life expectancy are we talking here? like 6 months wrapped vs 5 years unwrapped? I dont live where theres snow would that matter? or just the fact of having a wet membrane in contact with the metal for an extended period? ie: driving in the rain, then parking the car.

Rich:
I dont remember seeing such a setup on my car, i looked in my parts boxes and could not find it. Is there a reason to plumb the vent to the intake for performance or reliability reasons?


So, went to install the brake booster assembly, and whoa boy! What a PITA! Could not for the life of me get my booster installed, all to find out i didnt cut my valve cover enough >:O . SO, luckily i had an extra set that came with my engine, so fearing the same result i CHOPPED them lol. Bye Bye powder coated covers….
Looked like it was going to fit:

My hydraulic guy nailed the fitment here, 45 degree JIC hose end and a 90 metric to JIC fitting:

Silicone heater hoses are run, Booster/master and “new” set of valve covers installed. Still cannot figure out where the intake piping can go..(help?!? Lol) Lately its making me consider some headlight buckets.

Also, ordered my suspension and some of my braking parts last night. Here’s what I ended up getting, let me know what you think:
Weltmeister 250# AutoX Front Springs
Koni Yellow front shocks (to match the rears that I already have)
Weltmeister 28mm solid torsion bars
Zimmerman Cross drilled rotors F+R
Am considering bigger calipers from the front, and seems ive missed the boat as it were on XSCHOPS bad ass adapters. I know a lot of cars ive seen use the big blacks, and boxter, etc etc.. But im trying to do something a bit more uhm “cost effective”. Has anyone used the Wilwood caliper adapters from the VW busses? Apparently the NA 944 brakes are an upgrade for the busses(news to me). Theres an adapter for 150$, that uses off the shelf “universal” Wilwood calipers PN:120-6816 (120-6816RD for red) 175$ ea @Summit. So, roughly 500$ for a big brake kit that uses stock 944 rotors. I feel like this may be too good to be true, any thoughts?

2nd start:https://youtu.be/p2KOqSfETbc

Few minor systems like clutch, and brakes, then should be up and goin soon!

Sounds great

Great setup! I'm looking to hookup my late model with power wires soon! Keep it up anyone have a write-up for late models power lends?
