Brand new, one off custom turbo manifold to fit BMW E36 318i. The flange's are designed to take any of the garrett GT series turbo's. The heat wrap is in place to protect the spark plug wires, coming out from the power pack. The rest of the manifold has been heat wrapped to ensure, minimal heat soak into other engine components, and also to ensure maximum gas flow velocity. This manifold replaces the existing one, and the Y-Pipe. You will need to take your car to an exhaust centre so they can cut your exhaust just before the lambada sensor (on the engine side), and then flare the pipe so the downpipe slides in and clamps down. As shown in the picture. It is a very easy job and should cost no more than £30. Or if you are fairly apt at such things, you can do it yourself. The entire manifold and downpipe is made of stainless steel, it is tubular for better flow, it has also been heat treated against cracking. I have also wrapped it in heat insulating tape. There is also a lambada sensor bung in place.
The manifold is designed to be a top mount the turbo. This makes its far more easy to get a good oil drain and positioning of compressor outlet piping. It also makes a straighter and far more efficiant flow of gas for the downpipe. Plus it looks great to open the bonnet and see a turbo!!! The only two things that have to be moved in the engine bay in order to fit this and a turbo are:
* The windscreen washer fluid bottle. It has to be moved to make room for the turbo. A very easy thing to do, can be replaced by a sports edition bag, or any plastic bottle. * The top radiator hose. It has to be moved in order for the compressor outlet (boost) pipe to go down into the intercooler, or straight to the inlet manifold (whatever you decide.) Samco sell a replacement radiator hose that can be manipulated to get round this.
The manifold works with the M43 type engine. However it may work, with the M42 and M44 type engines. I'm not entirely sure.
The testing alone cost many hundreds of pounds to make sure it works, let alone the actual build. It is designed to be for the serious tuner/customiser. This is not a "turbo manifold" that you buy on E-Bay and have to hack your engine bay to get it to fit. IT WILL FIT STRAIGHT ON, NO FURTHER MODIFICATIONS ARE NEEDED FOR THE E36 M43 engine.. To whoever purchases the manifold, i will be more than happy to answer any questions you may have to help build your turbo BMW.
I probably won't buy it, but I'm just after technical information and advice.
It has been designed for use on an M43 engine, the sucessor to the engine in mine, the M40.
AFAIK, the only major difference between the two is the inlet manifold design the rest is just improvements.
Mine is a 316i and the manifold is designed for a 318i. Apart from the obvious differences (port sizes e.t.c) and assuming it fitted, would this work on my engine?
I'm assuming I would have to uprate the bottom end of the engine (rods? pistons? e.t.c)
How much would the right turbo cost?
How would I provide an oil feed? Direct to the turbo?
Adding an intercooler means I can have more boost?

You might be lucky and find that the ports are the same on both heads. The right turbo will be down to what power you would like to go for, for instance some turbo kits don't need the std engine modifying due to it being a low pressure turbo. I'd get on a Bmw forum and see who has done the conversion.
Cool mod joe, your car has a top speed of 120 mph, i know because i`ve done it in a 316i, although this is a cool mod its also quite expensive, personaly i`d just uprate the cams etc as you`d get more for your money and it won`t kill you on insuranse as the turbo would
I have fast road cams mate and it seems they haven't made the slightest bit of difference (don't know about figures though)
Regardless of cost, this car is a project car and always will be, I'm using this one to learn from (hopefully, not by mistakes) so the more I do, and the more I learn, the better
never thought about the insurance though.

Its easy to bolt a turbo to any car with the right manifold to fit it, the problem, and hard part os matching the fueling....
With a turbo, you cram more air in to the cylinder, this in turn needs more fuel. Heat is also generated by a turbo, again this needs more fuel.
In addition to the turbo, ideally you need a bigger AFM to measure more air, bigger injectors to supply more fuel, and something ECU wise to control it all
so could the standard ECU be altered enough or would a replacement ECU be necessary?
I've had a quick look on bimmer forums and the likes and nearly every reply suggested replacing the engine for a bigger (and then add a turbo to that if you still wanted more power)
They said even if the cost of the turbo kit is cheap, it's getting the set up right.

Just them other questions if you can answer them..?
bottom end need uprating?
How much would the right turbo cost?
how do you provide an oil feed? Direct to the turbo?
Adding an intercooler means more boost?

Depends how much boost you want to run... Turbo pistons are harder than N/A Pistons, and can take more heat and pressure. Rods are stronger, as are cranks. Manufactors that do engine with a N/A and Turbo variant, although the parts inside look the same, they are not - eg the SR20DE Nissan Engine, and the Turbod SR20DET are basically the same, but the "T" has a stronger crank, rods, pistons, thicker liners and oil squirters pionting at the pistons the keep them cooler.

How much would the right turbo cost?
Depends what you want to fit. A std T25 can cost £50, the turbo on my Nissan cost £700....

how do you provide an oil feed? Direct to the turbo?
Yeah, take a pressurised oil feed and run it in to the top of the turbo, the drain is then generally tapped in to the sump.

Adding an intercooler means more boost?
No, an intercooler cools the charge temp. Charge temps tend to get higher with more boost, though even at std, the cooler the charge temp the better.
Standard bottom end on nearly all BMs is up to the job;)(up to 10-12psi anyway) However,as stuy said its all the other bits you need that put the price of conversions up...
For all the work you would put in (and money)I would just convert to s52 engine and running gear(M3 e36) Either 3.0 or 3.2 will transform the performance overnight and is not actually that hard to do...you need a full damaged car(seen one for £2000)to do it. I would help with this cos it would be sweet...
And if your not happy with performance in the future you can bolt a turbo onto them as well(not cheap)to give a MINIMUM of 580 bhp!!
Don't plan on doing any conversions yet - still paying £200 a month insurance for a 1.6

You'd gain more power and it'd probably work out cheaper (and easier) to put a bigger engine in. I always hear people asking on forums how to make their 1.4/1.6 more powerful and the answer is to put a bigger engine in. BMW like Honda have had decades of making good NA engines.
Yeah thats the answer I found on a lot of other forums too
