924 straight six swap

I'm from Northern Ireland, to be exact country Fermanagh, my profession is as a mechanical engineer and recently in particular powertrain

Those are complicated rules and I guess set up to prevent modified cars but allow for the likes of industrial machinery like fire engines to power pumps. Here strictly speaking engine modifications and changes are not regulated we just have inform of engine number changes, but if the car is too modified, ie if the axles, engine and gearbox are all changed it will have go for an inspection and lots of paperwork but you still can do whatever you like. But a simple engine swap generally doesn't call for any inspection, however its insurance here is difficult to get at times...

If your limit is 150hp should happily get that naturally aspirated, I think it was TSR use to get a quoted 160hp from the I5 10v by boring it out and changing the camshaft and keeping the k-jet injection, so even keeping your current cam and building a 6 branch with mappable injection and ignition 150hp should be within possibility. I say building a 6 branch as I see from the other forum I spotted the project ton you TIG weld

Here is a video I made yesterday, when I took the car out for a cruise in the countryside.

Have been working a little on the EFI hardware, fabricating injector bosses, cutting off the plenum and drilling holes in the intake manifold.

I dont have a milling machine, so I made a drilling template, which worked fine.

Well, a lot of work has been done, and here is the result.

Running Megasquirt ECU. Over the winter I will have to change the ignition, so the ECU controls that also, I'm running fuel only now. But the vacuum advance is not working right and it was the plan to control ignition sooner or later anyway.

Here is a trip I took, before winter. The sound is much better now, with the 2,5" inch exhaust.

Congrats on putting it all together. I really like your intake. It makes one pause and ponder.
I bet it has some very good Torque curve as well. Keep up with pics/ vids.

Thanks.
I made the intake more or less from scratch, since the EFI intake manifold for this engine is hard to get and would not fit in the engine bay.

On some of the first pictures, you can see that I'm welding injector bungs in what is actually a manifold for the diesel version of this engine. Yes, the diesel and gasoline head has the same boltpattern for both intake and exhaust. All I had to do, was to enlarge the holes a bit (left=diesel/right=gasoline)

I cut off the plenumchamber on the dieselmanifold and made the new one with the long runners instead. The material here is stainless steel and I made a jig for holding the runners in place.

I also made a complete 2,5" stainless steel exhaust system.

The old downpipe to the left, which I quickly made from whatever I had in the workshop, was a complete disaster, flow wise, so I opmized that, when I build the stainless system.
