    Icon5 205 engines

    Hey guys ,
    What is the difference between the 205 GTI S1-2 UK and Australian engines.
    The Aus engines are 75kw and UK engines are about 100kw, what did they do to the Aus spec engine to detune it?

    Different head, poorer porting, less compression. All the things you need to do to kill an engines' Hp.

    Different cam too. The timing is really dull.

    To make a euro spec engine (minus cam) you need to get a series 1 block and a series 3 head. This gives more compression and larger valves. The series 3 cam is also better than the earlier one.

    Why not just buy a late model (1992 - 1995) 405 s, sri 1.9 ltr engine and if necessary, gearbox. It is the 405 engine that the 205 uses isn't it? Thats what I would consider doing if my engine ever died. Probably more 405 wrecks out there that 205 gti wrecks?

    Thanks guys.
    I've had my s2 for about 2 weeks, 1.5 of that it's been at Elliot Tune getting a new clutch, cv joints, tune, etc etc, Just got it back this morning
    It just needs a few bits and peices now and it should be sweet.
    I'll post some pics once I clean it on the weekend.
    I can't believe Peugeot went to all that trouble for us aussies, i'm touched. :p
    Our pertol wasn't a high enough rating, is that the reason?

    No, we went to unleaded in 1986.
    The series three engine was a lot closer to the european specs because it used a more sophisicated fuel management system.
    I believe the mono point system fitted to my SI to be better than the Bosch L system fitted to the series 1 and 2 GTIs. At least it is digital and has fully electronic ignition.

    J - You can get the S1 head cooking if you want.. i ended up getting some work done to mine that has made it pretty hot. Let me know if you want some more info...

    Dave is right. The 75kW DFZ block, as fitted to early 205's and 405's, has smaller piston dishes than the later 90kW DKZ(?) block. The chamber in a DKZ engine is 34cc compared to 49cc in the DFZ. So putting the two together produces good compression, around 10.5:1.

    Early 1.9L GTi's in the UK also had a version of the L-Jetronic, but without the lamda sensor.

    Thats right Peter, the DFZ block, with the DKZ head is the combination referred to. From memory the DKZ head was 38cm3.
    How much power did you end up getting out of your 205 8 valve engine?

    That's all true but if u can't find an SI head your up shit creek.

    That's why I said you can still get decent gains out of the DFZ head with the right work done.

    Default 205 Cti

    From what I can find Australia got the US spec CTI engine.
    The head block I used was a Jaz head on a S1 block and pistons as a start.
    Actually didnt mean to, Just managed to buy a brand new one (no more left sorry) from P504 services. Thinking it was only a S1 head It now has 2mm O/S valves inlet and exhaust and I think a Grp N cam plus lots of other fiddles different computer etc description MUCH better and torque! any one have a 6 speed gearbox?

    Yes, I'll need to clip your wings tomorrow. Hopefully I've now got all the bugs out of mine and time to extract my digit!
