2.0 HDI 90BHP fitting a turbo

[steve_earwig]

110bhp is for a 2.0 diesel? Well, perhaps now, but think when these engines were designed, hell they're based on the old XUDs!

yeah but there only 110hp with the intercooler without one there only 90hp so still thats no brilliant with the turbo, but going on age it ok, i must look into bigger turbos for the engine,

anyone know does the 2.2 HDI have the same turbo or bigger then the 2.0 HDI

thanks

Go and get it remapped, makes a massive difference to the drivability of the car.

GT1549P - not bigger, but it's variable geometry....

You can be forgiven for thinking the 90 has no turbo, hell you can't even see the thing without a struggle!

Re-mapping is the safest and easiest way to get more power (and economy) don't even consider trying to bolt on a bigger turbo. The standard unit is very reliable indeed.

All HDi's have a narrow power band between 1700-2800 rpm there's no 'turbo rush' as such, unlike the old 2.1td

Hi, if its a little more power you're after? then try a power chip, there a sinch to fit & give you a noticable boost

Surely whacking on an intercooler is first port of call?

If you want it to slow down yes.

Diesels rely mostly on the amount of fuel being injected for their power since the intake is just a big hole taking in the same amount of air each time, just cooling the charge air will do nothing without a new fuel map. In fact most remaps only really address the fuelling and leave the boost pressure alone or only slightly increased.

excellently put welly, ive been telling folks that for ages. It isnt intuitive that a diesels power comes solely from injection pressure and pump timing and confuses them that they are so different from a petrol, and as you say more turbo boost alone is no good either

to David (or anyone else wantin more grunt from a diesel) - a good cheap power mod is a tuning box, which only attaches (plug and play) to the fuel rail pressure sensor and increases injection pressure, if you cant afford a remap, which is just a cleverer fuel pressure increase but mapped to rpm and load instead of a "blanket" increase across the board. Tuning boxes can cause a bit of smoke at low revs as you open her up to pull away, and a good remap should not, but neither are always true, and both give bags more grunt. A tuning box can be had for £80 from ebay.

YAY, I did good

*runs to tell his mum*

thanks guys for the info i went looking for the turbo "i didn't try too hard now" and i couldn't find it anyone have any pics or links to pics

Thanks

Get the car in the air, get underneath and follow the exhaust up behind the engine, can't miss it (might need a torch of course...)

[john1412]

thanks i must do that
