new to diesel tuning - Tonibruce - 11-09-2013
Hello all, bought a 306 dturbo to drive as a daily car but am really bored off standard power now, so have bought a 11mm pump from a member on here, from what I have read I need a td04 or t25 turbo, front mount intercooler, 2.5-3 inch exhaust to hopeully get around 180ish hp.. Anything else I need? How bad will it be on fuel with this set up? I'm not new to turbos as my other car is a civic vtec turbo running 373hp that I have built myself with gt30 turbo etc. Its just iv never tuned a diesel before so any advice is appreciated!

advice:
read and search. All the info is on this site.
have fun

Standard Piggy reply lol.
Get up some pics of the civic in "The Couch" Im sure alot of other members would like to see that
Make sure you understand how the pump works before you start tinkering, you do need some kind of uprated turbo, but what you choose is upto you.
RE: new to diesel tuning - underground375 - 11-09-2013
Most popular turbo would be the TD04, but from what ive seen these last few weeks or more is people experimenting with different brands and types of turbo on the DT. Id still go for the TD04, but ill wait till I find out with the plates made .

It's fairly simple really. Add fuel until it coals, then add boost until it's clean. Repeat until it breaks something then upgrade or replace. Continue repeating

In a nutshell
RE: new to diesel tuning - underground375 - 11-09-2013
Way I did it was add the most boost the k14 would (24) Hmmm then add abit of fuel abit at a time until the coals was about the standard they was from factory!

this is a good start.. but the turbo boost will co-relate to the amount of fuel...many people running k14s at 30psi can testify to this.
yes it was the standard piggy reply...but by his questions it was clear he hadnt read up on the tuning guides on this site.
11mm isnt needed for 180bhp and td04/t25 is now a very old inefficient method of boosting. as would 3inch exhaust piping...
but all that gets covered at lesst once a week.
another prod/vote for a decent FAQ page with sparklers n flashing lights around it on the newbie page!!!

Pretty perfect summary of XUD tuning there!

Depends what you want. Go through videos on youtube of 306s with different turbos and decide what you want. Dont listen to Piggy.

These engines are only bad on fuel if you thrash them tbh...

Not even then, even beating the shit out of mine won't get it under 30mpg
RE: new to diesel tuning - Tom - 13-09-2013
Haha i only get 30's in mine!

Is it tuned at all? To be honest, i'll easily get between 180 and 200 miles from £20 if i'm careful and stay off boost and coal... But give it a thrash and that quickly drops to 50...

11mm pump, 2.5 exhaust and a td04 would be perfect IMO
Bolt on and reliable (ish) 180 bhp for peanuts
Get cracking!

Yeah it's stage one tuned to about 19psi, pretty mild.
RE: new to diesel tuning - zx_volcane - 13-09-2013
Also +1 for ignoring Piggy, don't know when he became so intolerant to new peeps asking questions, plus doesn't always give accurate advice himself.
11mm + TD04 FTW !

RE: new to diesel tuning - ADV_93 - 11-10-2013
TD04's are a good place to go if you want MORE power, or a GT2052S or whatever turbo people are fitting to XUD's this week... But it costs a lot (may be a few hundred-£££, but it's still a lot)

But in fairness it's dirt cheap compared to extracting more power out of a petrol engine for example
Bang for buck it's a bargain

Oh, absolutely! Diesels are so much easier and cheaper in comparison! In that case, yeah, it is a bargain!

I would still maintain that 11mm is not needed for decent power just a larger blower and a goved pump. As soon as I put an 11 pump on my motor it has always become unreliable.

I always thought the reason behind the 11mm pump setup was because the added fuel meant it could spool the bigger turbo? Isn't that basically what a map does to a HDi with a bigger turbo?
RE: new to diesel tuning - Dave - 13-10-2013
Haha I stand corrected. The 11mm just allows more fuel overall, higher boost and gets the fuel in faster, wont necessarily spool the blower sooner it will more likely bog it.

Hence why a Lucas pump won't run a TD04? Or so i've been lead to believe... Thought it was down to the increase of fuel = increase in exhaust pressure = spooling of bigger turbs?!
RE: new to diesel tuning - Dave - 13-10-2013
Lucas pump will if you open up the gov in it, in fact it would more likely respond better for top end (6k+) rpm if you can mod the gov properly because of how the pump works internally (info there for anyone interested). Increasing fuel does increase exhaust pressure but non more than what a 9mm is capable of. It will help it spool a tiny tiny bit more but nothing that's worth upgrading pumps for.
RE: new to diesel tuning - Mattcheese31 - 13-10-2013
11mm just means you can cram more fuel in in a smaller injection space, if you run a maxxed out 9mm you'd have much higher EGT's i would have thought, i'm not going 11mm though personally . .
RE: new to diesel tuning - Dave - 13-10-2013
You will have higher egts if your running more fuel on these things
