    Hi all,

    Guessing this may have been covered a few times but every time I try to search for 318 TDS it says too short or too common etc.

    I am thinking about getting a 318 TDS as I cannot afford a 325 TDS yet.

    I hear they are rather underpowered so was wondering if anyone could give me advice as to whether it is easy to get more power out of them?

    I would guess all the basic stuff of exhaust, good service, clean intake, intercooler and blank egr etc.

    But can you adjust the turbo on them and can they be remapped? Or are they too old and need a chip?

    If so can anybody recommend another thread/website with details etc or your own experiences.

    Cheers,
    Ben.






    Just found this on ebay. He claims that it does not just make ECU think car is cold etc and has sold seven of them. Found the good feedback from the 318 TDS chips sold too.

    I would still try and aim for a 325tds if possible, there is a big difference between the two.
    The turbos on each can be adjusted with a bleed valve, and I can do chips for either type.

    Would love the 325 but I do not get my years no claims until December.
    The 318 is the same price as my 1.5 VTEC-e Civic is at the moment. However my car is quite a bit quicker than a standard 318 TDS.
    However with some mods and a chip the TDS should be around the same power with more torque.

    Could you explain the bleed valve? Not done anything with modifying turbos really. Pretty sure I read somewhere there was a screw on the turbo you could adjust?
    And what sort of price for a chip?

    A bleed valve will vent off boost pressure which is used to open the wastegate and slow the turbo down.
    Venting off some of that boost makes the wastegate stay shut longer, and make more boost.

    Ah fairly simple then. Will have to google them and look at prices. Do they have to be model specific?

    Is there still any point having a chip if adjusting boost etc?

    Also what sort of boost do they run standard and what would you set it at? Got an old boost gauge of my Dads Pajero so that will be the first thing to fit to momitor that and to help if adjusting boost etc.
    Then de cat and egr blank etc etc.

    Sorry for all the questions but it is nice to actually get good info out of someone for a change!

    Changing the boost will only have a minimal effect, it won't make too much difference to the amount of fuel injected, and that is where the power comes from.
    The chip sorts out the fueling and does most of the power differences, the boost changes would either reduce the smoke levels and keep it cleaner, or give a slight increase if it is limiting fuel to avoid smoke.

    Have a look and see what the boost gauge shows, I can't find any data on what sort of boost pressure they should be running at.

    Okay thanks mate.

    Going to look at and probably buy Saturday so will be able to have a play soon.

    Will chat about a chip too.

    Well I bought it, seems to be cosmetically challenged but mechanically sound

    So time to start playing once I get it home next week......and save up to tax the bloody thing too.

    Started playing today. Removed rad, intercooler and pipework for cleaning. Also replaced thermostat.
    Started to blank/delete EGR as well. Blanked the vacuum pipe out of the vacuum solenoid to the right of the EGR and blanked the other end of the pipe off as it comes out of the EGR.
    Now I have to blank off the exhaust manifold and EGR valve ends of the metal pipe but the flange each end posed a problem. I want to completely remove the metal pipe but the flange stops me putting a normal flat blanking plate on unless I can get someone to drill halfway into it.
    My other option was to cut the ends off the metal pipe and weld up the holes and bolt them back on.
