    Default XU10 engines?

    G'day I've been doing some research and found that the late mi16 has about 160 HP and the late 306 2 liter twin cam/ late xantia engines have about 130. Where does this extra power come from? Is it in the head or in the bottom end? Different pistons? Different cam ratio's? or is it in the inlet manifold?
    Also does anyone have any idea what the difference is between the bottom end in these cars?
    I'm thinking of using a xantia engine i found with either the mi16 head or mi16 cams and manifolds. The engine i found has only travelled 81,000 km so should be a good basis! I'm staying opptomistic that the manifolds will bolt on the xantia's head!

    Any thoughts?

    I'm trying to go down this path because I cant find any low km Mi16 2 liter engines to start with! and the 306/xantia dont seem to give any trouble, so I'm hoping this will be the case in the 405! Hopefully I can build another engine identical to the one i have already but without the rattling noice that nobody can fix!

    Thanks, Chris

    I am reasonably sure the extra power comes from the cams and the manifolding (needless to say the computer is probably different as well). The CR is 10.4 on both.

    The use of the low km XU10J4R motor is a good way to go, no oil surge and factory built.

    Good Luck.
    Present fleet:-
    Peugeot 93' 205 Gti 16v
    Peugeot 73' 504 Ti from new
    Peugeot 08' 407 Hdi Coupe from new

    Previous fleet:-
    Peugeot 95' 605 Sv
    Peugeot 92' 205 Gti
    Renault 72' 16TS from new
    Renault 69' 10
    Renault 71' 10s

    The xu10j4 is a 2L iron block with a head almost identical to a 1.9L Mi16. The xu10j4r is also a 2L iron block but with a newer head, almost identical to an xu10j4rs. The valve and port sizes of an xu10j4r head are identical to xu9j4. As BIGRR said, the cams are the major difference. Just buy a low km xu10j4r and change the cams.

    Thanks peter you've just confirmed everythink i wanted to know!
    What sort of car does the xu10j4rs come out of? Would it be worth going that way or is xu10j4r a better way to go? Will the rocker cover form the mi16 bolt onto that head? I want to keep it looking original and use my coils etc so not to change any of the wiring loom!

    Thanks Chris

    XU19J4RS is GTI6 and Xsara VTS so not easy to find.
    The XU10J4R is 306 XSi and early 406 so much easier.
