DonnyDiesel aka Mark developed a wide range of performance parts for rover diesels. Unfortunatly he has moved onto other cars and so these are no longer available from Mark I believe. However I'll leave the links and pictures up here for information and reference.
These products aren't available anymore from Mark, but I've left the page up to give people ideas. Other companies do some products though if you are after something specific.
Being blunt the turbo outlet pipe doesn't make a lot of difference. It looks pretty, and it won't hurt, but it doesn't make a huge power difference.
Some people have uncrushed their original pipes using various means to get a better shape. You could even use flexible exhaust pipe instead if you wanted to replace it totally.
It all depends on what mods you have as to what is the next best "bang-for-your-buck" mod.
The best usual mods for the 25/zr/zs/45 are injectors from a 200/400/600 di, up the boost to 19psi, and a decat and performance backbox.
That little lot will give you 140 -ish bhp, maybe a few more.
Then to top that lot off a remap which should see 150 ish bhp.
Above that you are really needing a bigger turbo.
You can fit a FMIC but it doesn't give you a lot more power and its a bit of a mission if you aren't using a dual pass intercooler getting the pipework to fit.
i've already removed the EGR
this week I'm going to fit a decat pipe.
i'm waiting the delivery of SDi injectors from Dark ice design.
boost to 19psi will be done when injectors fitted.
after that, maybe i'will send my ecu to DID.
they are working with reidy remap... do u know?
I'm not sure to be honest. They'll upload a fairly generic remap to your ECU (thats all you can do without seeing the customers car). I'm not sure if it was a reidy one or not. I've not heard any horror stories though.
For my ECU stuff I'll use Dakta from mg-rover.org as I regard him as a friend. I've done work on his car and he's helped me out with my camper too).
I don't have a mappable ECU though, I' need to swap chips inside the ECU rather than plug a laptop into it!
, well done and very instructive for L-series!
