The low compression 11N, 12N, 13N, 15N, 16N, 17N, 18N, 19N and 20N engines were an alternative for people who wanted to use cheaper 92 octane, also known as Normalbenzin, gas. Although the savings were probably very small due to the higher fuel consumption caused by the low compression. The high compression engines like 19S, 20S, 20E etc used 99 octane aka "Superbenzin" gas. The Swiss and Swedes had their own emissions regulations, but those had nothing to do with the "N" engines.

Thanks for that.. I was told the Low compression 2.0L was a swiss issue.. and kind of rare ( for a reason ) . Learn somethign new everyday.

The 90 hp 20N wasn't as bad as the other ones, the only difference to the 100hp 20S was the 8,0:1 vs 9,0:1 compression. The rest of the N engines used 1bbl carbs while the 20N used the same K cam and 2bbl Zenith INAT as the 20S. They were made in tens of thousands and could be found in a Manta/ Ascona B or a Rekord E from -78 up to around -82.

Subtle but important mods.. on intake #13 ( Lucky 13 ).. due to printed prototypes finding issues.

#1 - I kept thinking the flange bolt pattern was off due to printing.. NOPE.. the FRONT bolt hole is NOT SYMETRICAL to the other 3 !! Its 1.5mm closer to the #1 Runner.. and the first alignment pin. This can be easily missed when you are using an old intake gasket and head. Also access to the bolts to the was a bit off. So redid the whole flange. 1.5mm may not seem like much.. but its enough to keep you from getting a bolt into the block.

#2 - My Injector openings were a fraction too small.. 0.75mm so couldnt mount the injectors.

#3 - The Lokar LS mount for the throttle cable was larger than I anticipated, fixed that mount.

#4 - Throttle body flange and opening a bit small.

So I opened to 66mm to better handle the aftermarket 60x60 throttle body with a 65mm venturi. Not a throttle body I plan on using but some may want too.

#5 - Added throttle cable mount to the upper side to help with any throttle bodies what have the cable come to the top or the left side. As now this fits all 60x60 throttle bodies.

With that.. I think I am done. Printing one more final test fit up.. and will then go to the next stage. The one piece Intake I had made came to me with supports on the insde.. good for fitment testing, useless for airflow.

So sending Bob the one that was made in 4 pieces and super glued together.. It dimensionally is the same for testing. May need some sealing. But it should work.

 

[GoinManta]

Now that most work has been done on the intake, time to address the high vs low part variants.

I BELIEVE as it is a simple flange change out. ( made the 2.4L flange a hair longer and port matched in 3D the transition, and move the bolt and pin location up the 13mm

y

I MAYBE able to get variants made for both at the same time.. ( say the initial order is 20, get 16 Low and 4 High... etc.. )

Would it be better to weak the runners specifically for the 2.2L/2.4L head ? possibly.. ( I have my doubts as to any major benefit vs cost aspect )

But of course getting ONE set of these intakes made will take a bit of investment, so making two completely different ones I would see as being not cost effective.

If anything, people have been welding flanges to the 2.0/1.9 intakes for the 2.4L for a while now.. so if its good for the stock intakes it will be fine with this one.

In anycase, this one at least is more than simply slapping a flange on the intake.. it does have a longer transition than one would get with just porting a flange.

 

[The Scifi Guy]

Looking good! 🤩

 

[GoinManta]

Found and ordered 60mm throttle body that will fit the new intake, has the IAC built in and they even removed the hoses for the water coolant lines for me. Has the ports needed for PCV as well.

Also comes with the bracket for the throttle cable ( I will remove and repurpose to the intake ).

Latest version is being printed, then once I have it fit tested I will send to Bob for flow testing with this throttle body.

Then it will be down to getting the price and answers on the intake and should be ready to price it and start presales for the setup.

 

[GoinManta]

I am done. SOON™ a complete custom EFI system for the 4 Cly CIH.. Designed to fit under the hood of an Opel GT (and thus really any CIH Opel ) with NO body modifications.
Built to run on Microsquirt or Speeduino or MaxxECU will be ready as soon as we get the prices and can go into production. Everything else is on order. Will come in both Low Port (1.5L/1.6L/1.7L/1.9L/2.0L) Head and High Port (2.2L/2.4L ) Variety.

The throttle bodies came in and are perfect, the final fitment was perfect with a few small corrections.

The intake is on its way to Rally Bob for flow bench testing.

Distributor shafts and bushings on order.

Great thing about this is that there are a number of TunerStudio setups already out there so even programming will be a breeze.

I am currently expecting the first kits to be about $1600. Which means with a Microsquirt and harness kit under $2000. This will include the Intake which will have a MPA sensor built in, the AN fittings on the intake side, the Throttle body with Idle Air built in, fuel rail and injectors ( 2000 4.0L Mustang), all the matching plugs for the sensors. Just have to source yourself the AN fittings for the fuel system, an ECU and the ECU end of the harness.

The first 20 will be available in the Summer/Fall of 2023 and I will ship to Europe. If you notice it fits under a GT Hood with no modifications to the GT body at all.

Great work Charles! VERY exciting !!!

 

[DavidF1972]

Looks great 👍 how is the fuel rail secured ??

So all the bits and pieces are ordered, should have everything here by end of the month. The intake, I am still waiting on pricing and lead time. Also by end of the month we should have the flow bench results as l well. I hope to be in production by March and possibly have in my hand by July.

I had to commit to 50 sets of all the components for the intake and have so committed ( maybe I should be committed to an asylum.. but thats another issue). As I am a small shop and to get these made will require a good bit of extra funding as I have already invested more than a few thousand into components..

So decided to do my own Kickstarter without using Kickstarter.

If I can get 20 pre-orders, then I should be good to get 50 intakes made. If I can only get 10 pre-orders I will probably limit the initial run to 10-20 kits and keep a few for myself and call it a day. If I can get 10 pre-orders

Option #1 - Intake & Fuel Rail & Throttle Body ONLY - $1150

Many kits do not include the mated plug for their sensors. Mine will, include everything you need.

Throttle Body (60mm)
Throttle cable bracket
IAC Step motor ( Built in to Throttle body ) and plug
TPS Sensor ( Built in to Throttle body ) and plug
MAP Sensor & Plug for intake
Thermostat Sensor & Plug for thermostat housing
Bosch 4 Wire wide band Sensor & Plug
Four Fuel Injectors ( 20lb / 3Bar / 14.3 OHM )

As you can see not including the intake the parts to make the EFI System whole is between $400-$500 worth of parts.

Option #2

ALL Above with Electronic Distributor - $1375

All the above along and a NEW Solid shaft distributor w/o weights & Plug Distributor comes with Hall sensor and built in pull up resistor for computer controlled Ignition. Along with Ignition Control Module & Pigtail connector

Will need to reuse your Cap and Rotor, and will need to either send me old distributor, or pull off the lower gear on yours. I have no cores, but will have new Pins I can send you if you elect to do it.

Note you can modify your stock housing or modify the new side draft thermostat housing from Opel GT Source)

You will also need your own AN fittings for the brake hose and fuel rail. The Kit will need an ECU and pigtail to the ECU. ( Not provided ) AMP'd MicroSquirt

PM Me if interested. I will be taking a small downpayment now of $100 to ensure your place in line. The $100 is refundable if the intake does not go into production or the flow bench testing doesn't go to plan. Shipping is not included, and anyone can get on the pre-order including those in europe.

Cool! That is awesome you were able to get it done! It will be interesting to see what the flow bench stuff tells us.

 

[itb gt]

Re the manifold Will it work under pressure ?

 

[GoinManta]

Re the manifold Will it work under pressure ?

No reason to think it wouldn't.. it will be cast or CNC aluminum.

 

[GoinManta]

YIKES!!!

Yea most the parts MOQ was 50.. to get a good price.. when 20 costs almost the same as if I got 40 at the price of 50.

You get the 50.

 

[GoinManta]

I realized when posting on the 1100 thread.. I had not put the info on the Distrbutor project here.

Its also done. We will have two variants.. a Wieght distributor that can run a coil like a 2.0L Distributor.. ITs real function is for the european market where they need new distributors for the 2.0L and 2.2L but it came up as part of making the distributor bushings and shafts for the EFI.

Which is this:

The difference between it and an Opel Dizzy. It is a solid shaft so you dont have to modify your old distributor ( Althought you will need the gear off the bottom )

IF you used a Megasquirt, a MAXXecu, a Speeduino, etc.. adn want to control the dwell and timing as well as the fuel you need this.

Now you can go wasted spark:

or coil on plug as well

If you want to use the distributor as a Cam trigger instead..

Easy enough..

That said.. the distributor I am using has this

That gap is enough for the ECU To detect #1. The Leading edges are all 90 degrees from each other.

Anyway the bushings and shafts are already in production to make this a reality.

 

[GoinManta]

We got pricing.. and it came down to quantity or quality.

The difference was small enough on price I am going with quality.

That said we will only have 20 intakes on the run. If they sell out and I have enough interest, I will make more. I have commitments for about 10 units already.

Intakes will be CNC'd out of three distinct parts, and then TIG welded. We will have Low and High port versions.

They will be media blasted, polished and surfaced treated, then anodized.

There will be an option for special colors on a PREORDER basis only for an extra $200. They otherwise will be coming in Chrome anodization.

Preorders will ship for free ( Small surcharge for european orders ) and pick High or Low port.

There will be a very limited number in high port that will be ordered for "stock" if I do not sell out of the 20 pre-orders.

So if you want one and have a 2.2L/2.4L head you will want to preorder.

Option #1 - FUEL SIDE ONLY - $1790 - Will, include everything you need. Including the O2 and Temp sensor and all connectors.

Custom Intake made of Machined Aluminum
Throttle Body (60mm)
Throttle cable bracket
IAC Step motor ( Built in to Throttle body ) and plug
TPS Sensor ( Built in to Throttle body ) and plug
MAP Sensor & Connector Plug
Thermostat Sensor & Connector Plug
Bosch 3 Wire wide band Sensor & Connector Plug
Four Fuel Injectors ( 20lb / 3Bar / 14.3 OHM )
Fuel Rail
AN Fittings - (2) AN6 and (1) AN8

As you can see not including the intake the parts to make the EFI System whole is between $400-$500 worth of parts.

Option #2

IGNITION SIDE Above with Electronic Distributor - $1990

All the above along and a NEW Solid shaft distributor w/o weights & Plug Distributor comes with Hall sensor and built in pull up resistor for computer controlled Ignition.

Along with Ignition Control Module & Pigtail connector.

Will need to reuse your Cap and Rotor, and will need to either send me old distributor, or pull off the lower gear on yours. I have no cores, but will have new Pins I can send you if you elect to do it.

If interested I will need 50% down minimum, full payment will be optional and appreciated to make it happen sooner.

 

[The Cub]

I’m keeping my fingers crossed. I think it’s great that you are taking this on. Just curious Charles did your design(s) go through the RB flow test yet, if so how do they stack up? Or is my question still a little premature yet?

 

[The Scifi Guy]

I might end up getting one.

Here's some thoughts:

I'm sure the flow will be adequate, it may have a little more flow than stock or maybe a little less, we won't know for sure. If the runners are roughly the same as stock, then I'm sure the flow will be roughly the same. The TB is bigger than stock, so there shouldn't be any bottle necks. If my extremely oddly shaped SSD manifold could flow as well as it did, I'm sure this one will flow just fine.

But, of course, the MORE POWER guys will never be satisfied, so, howsabout this option: Sell the 3 manifold parts seperately and let the buyer weld them up themselves. This way, the buyer could grind and flow and weld away anything that displeases them or that they imagine will create more flow and then weld it up themselves. They could anodize or paint or use some sort of other coating themselves.
