BMW k1100 16v 1380 conversion
After years of consideration and looking for the perfect solution which fitted my needs of more power, ease of conversion, fit within emission regulations and budget.
I have considered a 7 port head with fuel injection, though i learned I would have problems with emissions by using a cam which suited the engine. Therefore I would needed to have made a compromise with my choice of cam,
I also looked at various engine swaps, Suzuki, Micra and Honda. These appear superb, but I felt a little beyond my mechanical competences. Also I wasn't prepared to have the car off the road for too long.
Next up I considered the bike conversions, i almost bit the bullet and went for the AElynx kit. These conversions appeared a lithe too brutal for how I want the car to be.
So…..finally today I bought the specialist components bundle kit. (taking advantage of the Kroner/Pound exchange rate today) Maybe I call the build the "Brexit"
SC ‘K’ Conversion Kit
SC Bespoke Bi-metallic Head Gasket
Refurbishing, Machining and Assembly of your ‘K’ Cylinder Head
SC Storm 2 Engine Management System pre-mapped for your engine
SC Bespoke ‘K’ Wiring Loom, Ignition Coil Pack, HT leads, Coil Bracket and sensors
SC Ancillaries Kit (including Throttle Cable and Dipstick)
SC Crank Trigger Kit with Crank Position Sensor
Preparation of your A-series block for the ‘K’ head
De-grease, surface, re-bore, hone and centre main strap machining of your block
Pocketing of your pistons for valve cut-outs
‘K’ Exhaust Manifold
Billet Remote Thermostat
Even though I am now suffering from a sense of post purchase anxiety, I will try and outline the specs of the engine as best i can. All comments welcome.
1380 block prepared by SC and built by Guessworks
- MED Verto Ultra-Light ST1 Clutch Kit with lightened flywheel
- Pistons TBD
- Crank - balanced x-drilled
- Conrods - Standard balanced and lightened TBC
- Steel mainstrap
- I will use the SC ECU and maintain a narrow band Lambda (for emissions)
Gearbox
- From Guessworks TBD. I think a SCCR box.
- 3.4 Final Drive.
Cylinder Head
- Cam wise - I meant to ask SC which cams cam with the kit LT or RS. Depending on emissions I would like the RS cams. I need to confirm this
- I have asked SC to machine and add a standard mini oil cap into the head
Colour (the most important part)
- Block painted black and head painted dark grey.

I like it!!!
Men viktigast av allt:
-When can I try it?
![Very Happy :D](./images/smilies/icon_biggrin.gif)
"post purchase anxiety"
Dom här orden var nog det sannaste som sagts vid sådana här inköp
![Shocked :shock:](./images/smilies/icon_eek.gif)
Frågan är väl vad du ska registrera den som?
Ombyggt fordon eller amatörbyggt fordon?
Måste göra om lite mer då kanske?
Kanske "rear beam axle" eller vad tusan den kallas kan imponera på besiktningen som ombyggt?
Fram har du väl redan lite justerbara grejor, men om det räcker som ombyggd hjulupphängning vete f-n.

Re: BMW k1100 16v 1380 conversion
I will register the car as ombyggt.
I took the car to SFRO 2 weeks ago and he was happy that the car would be registered as modified.
As you say all the suspension is done (bottom arms, tie rods, hilos, uprated cones, rear camber brackets) all of these thing matter.
Also the brakes are now 7.5 4 pots , even though they are smaller that are more efficient than the standard 8.4 so he was happy with that also. Even the reduction in wheel size will be accounted for.
The change final drive and the change of gear box and diff help the car to reach modified status.
This is enough ( i hope). Otherwise as you say there are other options (rear beam, rear discs, alloy trailing arms, larger break cylinder etc).
You can try it in the summer![Rivstart :rivstart:](./images/smilies/rockstarting_mini.gif)

Re: BMW k1100 16v 1380 conversion
But your car is 1996, right? Catalytic converter and all.
Will it really pass as ombyggt fordon with that model year? Usually modified engines are not accepted due to emissions after 1975/1993. Or can you use the E85 loophole...?

Re: BMW k1100 16v 1380 conversion
exactly. The car must retain the cat and Lambda and will meet the current emission levels for the car.
The ombyggt status comes with the other modifications. I have had extensive conversations with SFRO and even took the car to them.

Re: BMW k1100 16v 1380 conversion
Se till att firman du beställer från förstår den ska kunna passera svenska krav på avgasrening.
Bifoga gärna exakt vilka dessa kraven är när du beställer, så blir det lättare för dom också att göra rätt.
Hade även kollat med detta företag: http://www.psimotor.se/ då dom vet en hel del om vad som går att besiktiga och inte!
Nu vet dom inte så mycket om "kojor" mer än vad jag plågat dom med, MEN kan säkert ge råd om hur vassa kamaxlar som ändå går att mappa så man kan besiktiga.
Ps. Du kommer hata dig själv om väljer 3,44 för med den motoreffekten lär den orka med en 2,95 eller 3,105 och ändå accelerera som fan!

Re: BMW k1100 16v 1380 conversion
Thanks for that link!
Yip I have had many conversations with specialist components regarding emissions. I will use a standard set of LT cams, there is a lot of flexibility with the valve timing especially the overlap duration. They are certain that the timing they suggest will do, but there is always lots of room for adjustment.
They have also integrated the use of a narrow band lambda sensor. Normally they would use a wide band.
I am not set on the final drive as yet. Current I have a 3.21:1

Re: BMW k1100 16v 1380 conversion
Förstår inte varför dom vill använda smalbandslamba istället.
Mycket märkligt! Rena stenåldern.
Det blir väl separat spjäll per cylinder på denna och inte ett till alla fyra cylindrarna?
Till en vass sugmotor vill man definitivt ha ett spjäll per cylinder.
Äh, SC har säkert någon bra förklaring på detta. Kan man hoppas.
Åh du! Bara få se och höra denna igång lär bli spännande![Cool 8)](./images/smilies/icon_cool.gif)

Re: BMW k1100 16v 1380 conversion
Det ska bli intressant att få se hur det går att få plats med den under huven. Ta massor av bilder!
Jag hade gärna byggt en liknande maskin själv. Fast jag måste erkänna att jag är för snål. Det blir inget billigt kalas.
Vad har du för tidsplan? När ska den vara körklar?

Re: BMW k1100 16v 1380 conversion
I am bit Snål (being from Scotland), so it was a really considered purchase.
I am trying to save money where possible.
Actually, I hope the build goes pretty quickly. 3 weeks and SC will have the head and block modified. These will then be sent to Guessworks in Engkland and he will build the short block up and build the gear box. Then all parts come to me for final assembly. I want to have it driving at the start of the summer.

Re: BMW k1100 16v 1380 conversion
So I have gone for a set of Omega pistons 7cc dish (73.5mm) which need to be pocketed for the 16v head.
Aiming for a compression ration between 11:1 - 11.5:1
Have also agreed with SC to build the short block, I didn't feel I could manage it myself.
Nothing fancy:
Standard rods with resized big ends
ARP conrod bolts
Regrind and balance of a standard crank
Jackshaft
And the omega pistons

Re: BMW k1100 16v 1380 conversion
I have also decided to keep my SPI fuel tank and fit either an mpi pump or a walbro 195l pump.
advice seems to be that an mpi tank and pump is a good solution. I have learned that the mpi tank is foam filled, which helps with fuel surge/starvation. Though I am not too sure. so for now I go with my current tank. If there is an issue I can always add a swirl pot.

Cleaned out the garage, car in the air.

Fuel tank removed. I will reuse this spi tank but with a mpi pump.

Removed the sump guard, bonnet and towbar. I intended to sell the tow bar but i now 8 holes in the boot floor, I cannot weld and don't have welder. maybe i just refit the tow bar.
Lets call this a gentle start.

I will be watching every step, i to have an SPI here in Sweden and want to upgrade in the near future. What have you done with your old engine?
