diesel tuning..

  1. #1
    hey guys,

    ok so after chopping and changing my mind on the "what car next" dilema i have made up my mind.

    not going to give much away but as the thread title suggests its a diesel (Mpg ftw!)

    2.0 8v TD 111bhp - 192 lb-ft standard.

    now ive never had a diesel before so have no idea what you can or cant do to tune them.

    heard of remaping/tuning boxs etc but thats about it.

    would anyone care to shed some light on this please?

    can you add bigger intercoolers, turbos, cams etc etc al that stuff, im a total noob!

    thanks guys :-)

    There gets a point, where tuning outweighs the MPG advantage...

    A lad on pug306.net a few years back, had a 306HDi, which is 90bhp standard.. Put a slightly bigger turbo on, FMIC, and had it mapped, and made 150-160bhp, with 40-50mpg easily done..

    Id say if you dont want to spend a fortune, get a FMIC, can build it yourself, buying piping, and an intercooler of any scrappy car that runs one.. Then have it mapped, sure you would see 30-40% power gain

    bigger turbo and i/c etc..but without knowing the car..its hard to know what you can do in temrs of ecu..and how much more power they can take

    im thinking its an mg or some form of vauxhall

    Defo not french, unless he added money to what he sold the last car for.. As cars in the last cars price range, are all the HDi units, that run 90bhp..
  5. #5
    dont say its a mg zr... im quite sure it will be

    can you get one for what you can sell a 206 gti for?
  12. #12
    110 406 hdi... Yeah... But its not that its an mgzr...

    Pick 406's up for 5-600 quid now...
    Moon milage mind but still...
  13. #13
    why assume there wouldnt be money going in?

    no one mentioned there not to be.....
  14. #14
    You know what it is...

    And im right... Mgzr... Only 4th time of saying...
  15. #15
    you are close..

    already a zr in the houshold though..

    I never, i went on the basis, if it was french, that he would have had to put money in to get something newer, but if he hadn't, it couldnt be a newer frenchy derv

    We know what it is now, so not to worry

    Turbo Diesel engines are easy enough to remap, but on a standard car you'll often find the clutch soon starts to complain because of the torque increase.

    And yes you can do many of the same mods such as fmic, intake, headers etc etc.

    Iirc there 1.9 and 110bhp
  26. #26
    i was thinking the vw engine tbh..but then though agaisnt it
  27. #27
    nah i dont like the VAG scene at all!

    its a MG ZS.. not to everyones taste but im a HUGE MG fan!

    oh and anyone who gives it the "not a rover" bollocks just stop there as you have already shown you know nothing about them lol

    Great cars let down by common k-series fault ruining them much the same as lancia had happen to them... Me personally dont rate them, however dad had one in, rover 75 178,000 on it spec'd really well drove well just got ruined as a manufacturer name...
  31. #31
    going to take a while to find the perfect one though, not many the way i want one in diesel but they are out there!

    missed a beaut 2 years ago and regreted it since!
  32. #32
    Tbh after me being a geek about the power figures how many cars run the same engine power outputs (not to say there the same engine)

  34. #34
    so.. back to the topic of this thread.

    anyone else like to share some info?
  35. #35
    I had my A5 done. Got an extra 40bhp ish. Pulls a bit better now and still returns decent ish mpg for a fairly big engine. Would recommend getting it done!
  36. #36
    ring pdtuning karl..theyll give you some info
    obvs a decent front mount and a decat/straight through will help
  37. #37
    I had a clio dci got it mapped and put a larger inter cooler + decat down at rs tuning in leeds and it give good gains and masses of extra torque.

    Induction kits are useless on diesels as they are free breathing so take what air they need anyway's as long as your filter's are pretty much free flowing.
  38. #38
    see i'm thinking of having my diesel remapped but I've gotta get rid of the 306 first for the cash,
    im tryin to decide if I go with a little less hp an torque or perhaps lose a little mpg and go for that extra power, 2nd option is also slightly more expensive as I would need a decat
  39. #39
    Basically with diesel tuning it's about pumping as much fuel in as possible and sorting the air flow.
  40. #40
    surely a decat would meen huge amounts of black smoke? id like to try and avoid this haha

    The de-cat on my clio was done and smoked like a bastard taking it to rs tuners. As soon as they had mapped it no more smoke except gear changes going balls out.
  42. #42
    ahh so once mapped properly it should be ok, thats good to know.
  43. #43
    dont actually know how many cats mine has its a 330d, it does mention on the site I was looking at that there might be an increase in smoke but nothing alarming

    Love these cars. Pappa used to have the zs 180 in yellow (first one ever made )
    Now he's got the Zt-t 190, and im driving the BRM.
    Very reliable and great fun to drive, all of them.

    People get put off by the HGF, but they're just faggots
  47. #47
    Quite alot of tuning options out there for these engines, for not alot of money. SDi injectors, remove EGR, remap and you will see around 140bhp. Pretty sure there are other D.I.Y things you can do to help release more power.

    I had a Diesel Zr Karl, bored one night - SO around 3am me and my mate turned up the boooost, felt much better after that :-)
  50. #50
    Don;t think it's been mentioned (I've had a quick skin read) BUT, Performance French Cars are running a section each month about dizel tuning. The guy that writes it runs the turbo diesel owners club UK (TDOCUK) and knows his stuff from the sounds of it. Were thinking about chopping in our MK3 golf GTi for a nice 306 HDi. then giving it a bit more fuel, a bit more boost and hopefully some nice subtle mods to freshen it up. There's one down the road in good nick... I might go and knock on and see if they want to swap!!
  51. #51
    Diesels are the future! lol, mines got a spec list as long as my arm. Drinks fuel when you give it a boot full, still really decent MPG when you drive "normally" I find anyway. Mines a 306 D-turbo. So no ecu, but sure most modern diesel it would be possible have a twin map ecu get the best of both worlds?
  52. #52
    Would you go for an HDi or DTurbo if you had the choice? I can't tell what difference their is?
  53. #53
    thanks for al your replys guys, some good info been posted up

    cant wait to find one that i want!

    HDi has an ECU, D-turbo can pretty much be tuned with a screwdriver, turning boost, and fuel up.. But then again, id rather have a proper map on an ECU, by someone who has a clue

    this^^

    hdi for "proper tuning2"

    limited by what you can do with the dturbo as once youve turned the pump and injectors up that's it..be lucky to get 140bhp at best out of that

    hdi can take bigger turbo and injectors and have the fueling and ignition properly tuned to make decent power

    a mate has a 306 hdi at about 180bhp

    another mate is putting an hdi in a 205gti shell..and will be running about the same power
  56. #56
    I see!! Spot on

    So the HDi can be set up with a better map rather than or as well as tuning things like the boost levels and fueling?

    I'd only want a decent power if it's economical too. The Golf is currently doing about 35mpg and we could do with getting a bit better economy out of something hence why I'd looking into the 306 as it looks like a bigger 106 which I like.

    i havent read all the comments on here yet but in response to the OP,

    i had an MGZR TD 115 with a decat and mafam box on it, thats all it had. did about 40mpg and its mid range grunt was impressive, 3-4K it woulsd accelarate (after some serious lag) pretty hard. I loved the car alot but though it was quick midrange it wasnt useable really and starting it up i dreaded as it just sounded so rough and awful, sounded like it had serious diesel knock but was assured it was fine.

    Had several friends with 306Dturbo's and my only comment can be though you hear good tales on the internet and hear of people with good ones none of the ones i have seen have been much cop. standard they are guttless but will do a genuine 55mpg, but turn the pump up and they rattle themselves to pieces at idle, every copper pulls you as everyone behind you has developed emphysema and like my old MG, the power delivery is useless. Also, as a result of the pump being turned up by someone who didnt know what they were doing the headgaskets usually fail, alternativly, they adjust the boost way out of line and something else breaks.

    Remap wise, a few of my friends have had cheap remaps done, the power has been noticably increased but a few have had turbos fail, usually on VWs i will add. but usually not bad. Having spoken to a few mappers they have all highlighted that to create a map you need to have the car on a rolling road, and every car being slightly differant after a few miles in regards to wear and filters, oil etc they all respond differantly. As well as this, any modifications you have on the car will alter the peramiters of a map. long story short, if you get a plug in and play remap, how do you know its not just a generic map from a ... 307hdi? most diesels have the same ECU so you need to be careful.

    My own experience, i have a C4 VTS HDi at the moment as a trog about. It had 136bhp as standard, a dyno revealed 12 of them had escaped. after a remap, with the boost at 21psi it made a sound 191bhp and just shy of 400ft/ib. does around 35mpg and is great! being a 16v diesel is isnt quite as breathless higher up in the revs so drives more like a petrol.
    But still imo, my VTR is the better to drive, i get 50mpg driven steady and when its not its a right hoot!

    Thats just not true.....

    Youll find they are both equal as far as mods go

    the d-turbo is basic. no ECU messing things up, no sensors, and all you need for a stage 1 is a basic tool kit, which will see anywhere from stock to 140-150bhp (probably more with the right tune and pump mods) its just trial and error really

    a hdi stage 1 remap will see 120+ but depends who does the map

    obviously, both being a turbo car you can increase modify the turbo,injection,exhaust, change the intercooler in the case of the DT or add one for a hdi and so on

    Feel free PM me with any questions, I've got a dturbo running close to 200bhp at the moment on a poorly turbo
  59. #59
    on what turbo at what boost?

    mate is running a scooby td05 at 35psi and still hasnt touched 200bhp.....
  60. #60
    Thats because its a scooby turbo.....Mines a one off hybrid you wont see another running gauge only goes upto 30psi, flies straight off.

    If you can find me a 50psi gauge for less than a million pound I'll tell you exactly
  61. #61
    I've seen a few 306 diesels tuned and all they do is sound shit and chug up more black smoke than a coal mine.

    Leave it humble and enjoy the decent economy IMO.
  62. #62
    is your car blue? i think ive read your thread before on another forum..

    youve taken my post out of context by the way with basic mods IE the screw driver..the dturbo and hdi are equals..to get big power IE what your wanting to/doing..its easier with the hdi for the reasons i posted

    i say hes running 35psi...hes not running an actuator...just massive spring to keep the wastegate shut

    Karl listen to Uncle Gav turn the boost up nice big fmic remap it enjoy fund it by selling more doirty socks

    I'd love to smoke the chavs with a derv though.

    Have an exhaust pointing to the curb and then BOOOOM get smoked.

    All smoke, no poke is often the case. . . and what kind of headgasket and valve springs do you use that withstand 35psi of boost going into and engine with an 18.1 comp ratio! Jesus that's got some pressure in there.

    also want it to be "safe", dont want to be forever changing turbos etc etc

    Lad I know is just an hdi with big front mount, alloy boost pipes, a new manifold and downpipe, running a scooby tdo5 with the actuator disconnected and a big spring behind the waste gate trap door lol

    Mapped up with bigger injectors

    Made about 180bhp and daft torque
