    Turbo Technics - V6 Cologne - Capri 2.8i - turbo specs

    Hello

    I'm trying to find the exact specs of the T3 used in the Turbo Technics Capri 2.8i/V6 Cologne.

    Any help is appreciated.

    Also, if anyone has any componentry of this kit which is willing to sell I would be interested to hear about it.


    Thanks

    I can't help you what size or spec the original Turbo Technics turbo was but I think it does not matter much. You better select a turbo that fits your engine. A red light racer or an endurance engine, 200 Bhp or 400 Bhp. That's most important.

    I've been using a Sierra Cosworth like turbo but larger exhaust AR 63 instead of .48 on my 2600 May Replica Capri. Just to get rid of the exhaust gasses faster, helping the engine to run cooler.

    For pictures of the setup, check the dyno plot files.

    Agreed. A T3 is pretty basic and fairly outdated these days - there are better choices unless you are trying to restore to an exact state?
    Staying with Garrett a GT25R or 28R with a AR in the 60 range could work nice or Mitsubishi TD04 - 16T or 18T as alternatives. I'd go for a ball bearing type
    and water-cool it if possible. You may be stuck with an integrated wastegate but its not the end of the world - just external gates work more efficiently IMO.

    Correct, again, alle depend what you are after. For a simple basic turbo engine, integrated wastgate keeps it even more simple. I would also go for T25-28. But I still got several of these T3 turbo's bought them many moons ago in one auction. Last 2 will be used on my MX5.

    PS, for a cheap setup, Maxspeedingrods sell. T28 for a very low price (not for racing but good enough for fun).

    Thanks both for your replies.

    But I'm after the exact specs of the Turbo Technics Capri 2.8i kit.

    Any help in that direction is absolutely appreciated.

    specs will likely be ancient and very poor performing. Not worth trying to replicate, unless it is for some sort of concourse restoration.

    And by looks of things, a horrific turbo inlet.

    https://www.kgfclassiccars.co.uk/vehicles/2316/



    Also, some googling suggests there might be more than one, as some data lists a TT076, another a TT093 turbocharger.

    Would Turbo Technics themselves not be able to assist ?

    If I compare the numbers, my kit is at least as effective as the one sold at Turbo Technics. Hard to beat a low pressure turbo carburetor setup.

    Mine was 2600 cc, not 2800 which also have bigger valves. And no intercooler

    That's really an interesting set-up, experimented with blow-tru's in the 90's too, and yes as you said they are awesome when set properly.

    Haven't tried TT yet as from other threads I have noted that they are not forthcoming with regards to such queries.

    This one is setup properly. The carburator has some small modifications. The modified carb was so easy to tune I had it ready in minutes on my dyno. The rest of the time I've spend on the dyno was just a control to be sure.

    Ignition has the right mechanical advance, vacuum advance for lights load running and retard +/- 2-3° on boost.

    Would be easy for them to post a little more detail online then, and avoid all the calls.

    Although as said, can't really see why anyone would want to replicate such a kit, unless for absolute purist reasons. Modern turbos are just so much better, and plentiful in sizes

    rest assured that if someone needs to replicate such a kit there must be valid reasons.


    Meanwhile, i still appreciate any help both in terms of specs and possibly any parts.

    always assuming theres someone who actually knows that info! those turbo kits were made a long while ago most people who were involved with them are probably retired or dead!

    you try ringing Microsoft and asking them about windows 95!

    Posting such a question here is addressed mainly to a possible owner of such kit, familiar enough with the parts and most importantly willing enough to share such info.

    hopefully such an individual is active on this board and one day or another will be gentle enough to give me some insight.

    Same as I was thinking. But, compared with the Turbo May kit, not many of these kits where sold out of UK. No idea how many the ever sold (May round 5000). Even May kits become rare now.
