    Turboing a 2.8EFI cologne

    Right I'm fairly new to this engine set up.
    How easy is it to turbo this engine???

    Thanks very much in advance

    Rick

    P.s
    I'm only going to be running it on standard internals at a low pressure like the 200 BHP Turbo technics Kit
    Will I need to fit a high pressure oil pump???

    Re: Turboing a 2.8EFI cologne

    Like all builds not that easy to do, but, the basics are okay. You need an header with turbo, and a crosspipe,like in the turbo technics kits, or fabricate one yourself, but the tt ones fit a sierra, and you dont have that much space to work with. In a granada / scorpio just a bit more room to play with. Next step is fueling and retarding. You could use a aftermarket ecu, using the 2.8 sensors and injectors, or you could find a turbo technics dcu using a mapsensor and two extra injectors in the throttle, controlling the extra fuel and retarding.

    I didnt check,but it seems the early 2.9 ecus fit your loom, and the injectors from the 2,9 are 200cc, instead of the 140cc in the 2.8. Boost hoses and an intercooler is some puzzle job, but it is quite good to do! Im doing the same, only with 2.9 rods and pistons, to lower compression, and a few extra parts like a crack brace and an high flow oil pump. The max fuel added bij the turbo technics dcu is enough for about 285 pk, the used super 60 turbo has enough breath for 325 pk.

    If you aim at 200 bhp you wont need a high pressure oil pump. In fact, your better of with a high flow oil pump, the turbo has an oil restrictor for a normal oilpressure, if you have a higher oil pressure the oil gets trough the oilseals, making your engine a nice smoker!

    Not wanting to be a pessimist I would say avoid turbo 2.8colognes as mine was nothing but trouble. Spent a fortune on mine and got fed up with it going wrong so i got rid. A 24v cossie would be a better bet

    Re: Turboing a 2.8EFI cologne

    It depends on what breaks. The 2.8 mfi has some weak points. Cranck bearing number 3, and the in and exhaust manifolds are pretty resisting. The tt kit still uses those manifolds, but the efi inlet is already ways better, it even has 6 inlet tubes in a decent size, instead of the 4 on mfi. As long as the fuelingis right, and you use decent materials, like good big end bolts from arp, and just using good gaskets and headbolts (the victor reinz headgaskets are the best, only custom gaskets are better, but they cost custom money). On 200 bhp, you wont have big troubles, but things like improve the cooling in the heads can use some tlc.
    Ifyou want big power, use a 2.9 twin turbo, if you want serious big power, use a 24v twin turbo, but remember, the cologne v6 engines dont like over revving, and has their weak points. But if you build your engine with the weak points in your mind you can build a reliable 2.8 turbo for fast road applications!

    Re: Turboing a 2.8EFI cologne

    The 2.8 twin turbo we built in a MkI Capri had big problems with overheating (running over 1 bar though, a bit more than 200 bhp...) until we removed the internal thermostat and went to an external one in the top hose. Then it all worked fine.

    I'd say 200 bhp is easy, no internal modifications needed at all. But to get it to run really sweet, fit a Megasquirt and some larger injectors.

    Re: Turboing a 2.8EFI cologne

    Hey Gustaf just seen the thread I started over a year an a half ago.

    Already megasquirted it and the turbo is off at the mo as I have just rebuilt it.
    You were saying about moving the thermostat to the top like the pinto...
    Have you got any pics.

    I can definately understand why you have done that.
    Stange place to put a thermostat in the cologne... Although it does warm up quicker in the winter.
    I have an ally rad in mine so it does rarely get over 1/4 up the capri gauge

    Cheers for the info.

    No pics, sorry. We got an external thermostat housing from a friend, don't really know what is was for...

    Re: Turboing a 2.8EFI cologne

    Hi, I'm not turboing mine but its got Stage 3 hds and high lift cam, with tubular exhaust manifolds. Does the 2.9 inlet manifold (which I know nothing about), fit straight on and therefore allow an increased flow INTO the engine. And is there any value in the bigger injectors, or do you need megasquirt to go with???.

    Re: Turboing a 2.8EFI cologne

    You can get a 2.8 EFI manifold from Sweden for example, it's an easier solution.

    With ported heads etc. you need a good remap, bigger injectors or not, to take advantage of the tuning. Megasquirt is a nice, cheapish option.

    Re: Turboing a 2.8EFI cologne

    Hi, as you've probably found out by now the EFi kit for a 2.8 is very rare - being that Ford only used it for a shorttime as they were developing the parts for the incoming 2.9 Cologne. I too just like you was going to EFi a turbo 2.8 and collected all the parts to do so over a number of years. Times have changed and the 2.8i turbo is long gone in a mass clearout of my capri garages last year. So I'm about to list this on eBay as I rarely check my various forum accounts!



    But basically what I've got is:

    2.8 EFi kit complete with manifold, injectors, injector wiring, throttle body. Plenum and throttle body cover diamond cut with black paint. With it all comes a pair of alloy rocker covers that I planned to hav painted the same way. Just image how good that'll look! (I built a black 2.8i for my wedding that is also about to be listed on eBay). So with it all comes a new boxed EFi distributor, new 2.8i water pump, 6 new in box spark plugs (Champion RN9YC), a spare 2.8i front pulley, a new 2.8 EFi gasket head set and a pair of old (but uncracket from my view) 2.8i leaded capri heads. As well as that lot there are the 2.8 EFi particular water pipes and hoses etc. I don't have the original EFi ECU or wiring etc as I was planning to megasquirt. My belief is that a 2.8, turbo or not, would be greatly improved with EFi and a decent ECU with rollingroad set-up. Id expect a substantial increase in the smoothness of power delivery (most likely more sooner) and a requiste increase in efficency. I wouldn't like to estimate what sort of power increase there would be but the EFi manifold / plenum / throttle body is much more efficient than the MFi so with gentle porting to smoth the exhaust flow while you're unleading the heads etc I'm sure you'd have a substantial increase in relation to the little outley compared to old fashioned tuning limited by teh EFi. (Don't get me wrong, I had Specialised Engines rebuild my 280's engine to Stage 1 and it was as if someone had mixed the best bits from the Cologne and Essex engines but it cost a hell of a lot!)



    So, either look it up on eBay and bid or try comtacting me through the message here - as I said I don't look very often so I may miss it unless it fires an email to me!!!

    Re: Turboing a 2.8EFI cologne

    Hi, I wouldn't be interested in the heads, rocker covers (mine are colour coded), or the water pump, but am interested in the rest. I would still need to buy megasquirt, so how much for all the other parts. Is the 2nd front pulley to be modified to fit crank sensor?.
    Cheers

    It might interest you to place a 72 minus 2 cogged wheel onto the distributor shaft

    Re: Turboing a 2.8EFI cologne

    Hi I'm trying to build a 2.8 cologne turbo for my xr4i. Any tips and advise would be great.I have a 2.9xr4x4 for the running gear etc
    read about injectors is there anything else that would come in handy and worth me keeping it for?
    Kind regards Dave.

    Re: Turboing a 2.8EFI cologne

    Nothing really of use but you can try the 2.9 EFI manifold and see if you can modify it perhaps. I have seen 2.8/2.6 carb intakes modified for the 2.9 so the reverse should be possible.

    IMO, EFI is superior to working with the old K-jetronic/MFI from the XR4i. If you go that route, all the EFI hardware (fuel rail, regulator, TPS, temp sensor etc.) from the 2.9 works great with aftermarket management, such as Megasquirt. Just choose some larger injectors and you're good to go for 250-300 bhp. But then again, it's even better to use the entire 2.9 engine :-)

    Re: Turboing a 2.8EFI cologne

    Thanks,I might have a go at modifying the 2.9 inlet manifold as I using the 4 wheel drive system would make abs wiring easier if I was to us all the loom out of the xr4x4.
    Would like to keep the 2.8 as I have stage 3 heads to go on.Its something for me to consider thou.
    Thanks

    Hi 2.9 inlet manifold won't fit,couple of fixings in a different place,plan b is to make my own fuel rail to suit 2.8 inlet manifold.
    Post some pic's if I can sort it.

    Re: Turboing a 2.8EFI cologne

    Hello all,

    I have had one EFI version Cologne 2.8 engine sitting in my garage now for a while.
    Does this engine and fuel injection type have lambda version too? Or, is it just with MAF sensors?

    Will keep the engine in my posession for future, as it seems to be coming a rarity.
    Just bought the wiring harness, EFI box and MAF sensors for the engine.
    All the hardware is also accounted for EFI bits.

    Cheers

    Just MAF sensors, no lambda on the 2.8 EFI's.

    If someone has all the intake parts for the 2.8 I would gladly buy it.

    Have one extra set.
    Downside is that parts are in Finland.
