    Default What to upgrade/replace during 205 mi16 conversion?

    Hi All,

    It looks like I've found my mi16 engine! I figured I may aswell upgrade/replace other parts since the car will be off-road for a while.

    The car is a S1 205 Gti.
    • Engine Mounts..If they ain't broke do you fix it?
    • The Brakes are worn and need a change.. what's a good upgrade? Find a set from a 206?
    • It's hard to explain, but it feels like the front wheels are about to roll off on sharp turns. Could this be worn Driveshafts or some kind of bearing issue? Where could I find replacement shafts?
    • Mi16 Timing belt kit, $230 from EAI. Is this ok or should I look to purchase elsewhere?
    • Anyone have a Quaife LSD for BE1? I don't plan on hitting the tracks but is it worth the upgrade?
    • Is there anything else I should be looking at doing? Just pretend this is your car for a moment with no budget


    As you could tell I'm punching way above my head with all this but I'm keen to have a go. I'd really like to get this done right first time. Thanks!

    Engine mounts: fine
    Brakes: 206 is a great conversion even if its only the fronts and 205 drum rears. Master cylinder upgrade a must.
    Quaife is worth it.

    Replace strut top bushes and check the wheel bearings with the driveshafts removed. Check LCA bushes.
    Worn back end will make the car handle odd and twitch too.

    i bought my timing belt kit from UK $140. Cant go wrong - not sure what brand the EAI is. If genuine, better i think.

    Check all connectors - mainly FI, Coolant sensors, Oxy sensors

    If your handy with a crimper and soldering iron, i would replace these with new ones which have a better clip (much easier to take off)

    you can even find the different coloured ones for CTS and Oxy

    Assuming the bottom rear engine mount & bearing is the same as mi16, and is out of car - check thoroughly for cracks, or replace with one of those two piece poly bushes which i have heard are good (do some research tho) and easier to replace again in-situ. Also i would replace centre bearing.

    Water pump and remove heater bypass circuit. Use the aluminium water distribution block from the 205 (if it has one).

    Gates is the best, the genuine belt I have is made by Dayco.

    Thanks for the responses. I've purchased the Gates timing belt and now chasing the others, in particular the water pump, Quaife and some 206 brakes.
    My research tells me that my S1 GTI wont fit 206 brakes without replacing the Hub? I've searched the entire forum with conflicting results. Has anyone done this themselves?

    PeterT... What's the reason to remove the heater bypass circuit?

    You'll need Si hubs if you want to fit late model brakes with small driveshafts.

    The bypass circuit is only needed in 405's in cold countries, so the engine warms up faster. A 205 doesn't have a bypass circuit, so why fit one? It also eliminates two hoses that may otherwise fail.
