EFI with BMW 16V twin cam head
Turbo Mini Forums

would going to the port per cylinder make it dead simple to tune and get it correct vs the 5 port

surely its easier to make reliable power with the 16v head no?

Well yes it is more simple, no charge robbing or anything like that. Takes all of two hours to map one on a RR usually.

who makes the best simple bolt it on and go kit? and heads ready to rock?

i just want the easy way to 16v turbo

sick of all the hassle of carbs and shops not wanting anything to do with it

get in and drive it something easy for the local shop to setup and get 100%

Specialist components offer ready to go efi

What about 7 port ? Much easier than a 16v conversion. You can use your current cam, rockers and exhaust manifold. If you had the bits needed you could do it in a few hours.

ahh sounds a more simple option whos 7 port would be your choice phil?

just looked at the price of the med track day 7 port head yikes might as well stick a k head on there

med want 1800 gbp for the 7 port and specialist components for the conversion kit and a referred head 650 and 970 so 1620

look at the SC 7 port, its a better head, and a fair bit cheaper I think

Whatever you choose to do, fitting different heads in 16V or 7 port guise is going to cost a serious amount of money.

The question is whether this makes sense when going forced induction. It does maybe from a setting up point of view, but anything below 170HP is quite easily achieved using a 5 port head, mapped ignition and the trusty old SU.

If I were you I'd try to replicate a known engine spec correctly set up in the UK...i.e. Run the same head, CR, cam, turbo manifold, turbo, and intercooler. Then it's simply a manner of running the same map and needle. Perhaps someone like Benross can assist in this for a reasonable consulting fee to pay for part of the rolling road investment that went into the setting up process?

Alternatively, wouldn't Russel engineering in Sydney be able to point you in the right direction when it comes to setting up SU's 'locally'?

As a 3rd option you could opt for specialist components 'electronic carb' injection kit for the 5 port head. This can be used in turbo applications although the injectors can 'only' flow to about 150HP....fitting larger injectors might screw up part throttle no boost resolution.

All depends on what you want to get out of your engine I guess.

thanks guys i think im going to try switching back to unleaded fuel with a BDD stock needle and see how that goes

eventually i think ill end up with 16 valves it will likely be a second engine tho as i dont want the car off the road for to long

alright guys so ive decides to go 16V but wanted to know where the best places to go read up dose it matter what k head it is like is there a part/casting number thats preferred? or can any K1100 head be used? also would it be best to use a 1275 block or common 998/1098 blocks?

to be fair i should have just gone with a non a series engine from the get go but now having so much of the mini stuff its a no brainier to use what i have and just get the rest

As you're in Oz, you need to look up Matt Reid (the mini man) and see if he has some kits available. Alternatively www.force-racing.co.uk or Specialist Components

You need to decide if you want to do the small bore or the large bore. If small bore, you're limited to the K100 8v head.

lots of info on here, search under bimmer, twink as well as the more obvious k1100/1200

easiest thing is 1275 block, and any K1100/K1200 head, some 1200's had longer higer lift cams (RS was 285 vs the LT and GT's 252 deg) and smaller valve stems, apart from that they are basically interchangable.
