why are you using long runners if supercharging?

I must admit that I've always had a thing for long shiny runners going across the engine

Today I have been working on the intake manifold. Made a template for holding everything in place and gave the runners a few weld spots, so it is now one piece. Still need to close it and add the throttle body flange.







Trumpets inside.

Nice work, very impressed with the jig...
fun and games getting into those gaps between the runners...might be a little easier than my headers as the gauge is similar...
assuming you'll have some kind of support bracket for the plenum too?
once again great work

Thanks Stu.

Yes it took some time to build the jig, but it paid off. The runners are placed nicely now. There is a support bracket under the plenum, yes.

The manifold is now fully welded and polished. On the underside are a few vaccum ports; for the brake booster, the Megasquirt and a future idle valve.



The flange for the throttle body has been laying around for more than 10 years. I made it, when I was working at a place that had a water jet cutting machine.



The 36-1 wheel had to be bored out to 30mm, and the chuck on my lathe cannot open enough to hold the wheel, so I made a holding tool instead.





I did off course not take the tool down at any time. Welded and drilled holes before I put it in the chuck, machined it out and installed the wheel right after, so it is perfectly centered.

Since last time, I have been fabricating brackets and finding parts. Mostly fabricating.....

Here is an overview of the result.
Fuel rail + pressure regulator
Intake manifold (throttle body from a VW Golf III 2.0 16 Valve)
Hub adaptor for the 36-1 wheel and poly-V pulley
Alternator bracket
Hall sensor bracket



The arm that is protruding from the back of the alternator bracket looks a little thin, but it's an L shaped profile. It is visible on the upper picture.



70A alternator from a VW Passat.

I need to paint the brackets, and then it's assembly time.

These days I'm working on the wiring.



Yes, it looks chaotic, but it's going quite ok.

The ECU will be installed on the tray under the glove compartment, and the relay board on the back side.

All the hardware for the engine is ready for install. Well, I'm waiting for some parts that I have sent in for powder coating.

I need a new fuel pump. My plan was to install the old one, should be ok for a start, but when I installed it and hooked it to a battery, to hear if it was still alive, I discovered that it was leaking.....

Thanks, it does not have a single crack

The previous owner replaced it in the late 1980's, I believe, and the car has only seen the sun for a couple of hours at a time since then. Kept in a garage mostly.

The steering wheel btw, I bought that, brand spanking new in 1994 for the price of 660 USD !!!!

I never liked the original two spoke wheel, and Ebay was not invented at that time, so I had to drive a long way to a Porsche dealer and pay the price.

I still have the original cardboard box it came in

And now, an oil cooler. Plenty of space for that behind the 951 front.

That 924 is getting so much quality work it makes most others look neglected

Thanks Morghen. The car actually looks a little neglected these days, it's bit dusty. It stands next to the car I use every day, so dust will accumulate. But as soon as it can run under it's own power again, I will give it a shower

Still working on the wiring. Pulling cables from the ECU in the passenger side(right), pass the heater, and through the firewall in the drivers side, in some existing holes.



When I was laying with my head in the foot well, now and then getting strangled by wires, this disturbing scene from Superman 3 came to my mind....



Anyway, this afternoon, all the wires are tied up, inside the car, now it's time to connect them to the different sensors and injectors.



I'm adjusting the valves, and the cover is in for powdercoating. So until the cover is back on, the papers protects the cam from dust etc. This engine has valve adjusting shims, so I had to acquire two tools for that job.

Still working, but getting closer to an engine start.

Original Bosch 044 fuel pump, no Chinese aftermarket crap. Fits more or less in the original bracket.
