turbo shoping

[brock hdi]

Right am about to go turbo shoping is a td 04 any good for a hdi just coz I know for 1 plus can you put a screamer pipe and a wastegate? Don't even know if you can put them on a diesel

[cwspellowe]

They're good for gov modded XUD's. HDI's don't really rev enough for them to use them properly. Look at stuff like the Garrett GT's, much better suited. Just ask Jonny23-121213213111

Wot about turbos off vans

[hdi shaun]

Iveco daily turbo hybrid into stock exhaust housing would be a good one

No, no, and NO!

Seriously don't go to the effort and cost of making a hybrid. Get a standard turbo and hold it next to something like a GT20, you'll see why. The inlet and outlet on the stock blower are really tiny, it's just going to be less efficient.

[brock hdi]

I'll ebay gt20 turbos now wot cars/vans are thay on?

There isn't a definitive best turbo for the 306 hdi, it's all a matter of what your after. The TD04 isn't the best option for a HDI but there are turbo's that work such as the gt20 as said above, but again you will need to find away of mounting it to the exhaust manifold as the flanges are different and also setting up the VNT aspect of that turbo. I'm sure Jonny can help you with that as he's already done it.

How much power are you aiming for though? And what mods have you got already? There's no point fitting a huge turbo if you going for like 120 - 150 bhp as this can be achieved on a standard turbo using other mods. That will then keep your power lower down in the revs making it more driveable.

If your going for more then yeah you need to start looking at the turbo, but remember there are other mods that are vital to go with it. The main thing id consider when looking for a turbo is where do I want the power... The bigger the turbo you go for the further up the rev range the max power will be, and lag will also increase as it take longer to spool, hence diesels being fitted usually with smaller turbos.

I built a Iveco daily turbo 2.3 HPI hybrid recently (K03s basically the gt17 equivalent) it didn't really take much effort and its was pretty cheap in terms of turbos. I bought the unit of ebay for £90 then took it to a turbo specialist and had it fully rebuilt with 360 bearings for a further £220 so £310 is pretty good if you ask me. And its gonna be a solid unit as the specialist rated it to 30+ PSI.

Another thing to consider is whether you want a VNT setup or wastegate setup? VNT's are more versatile in that they come in earlier in the revs but can carry on for longer when compared to an equivalent waste gate turbo, but they are harder to setup and it will require some research, I believe there's two methods of doing it. Obviously a waste gate setup is simple in that it just goes on like your original and off you go, plug and play affair.

Its all just a matter of what power you want and where you want it, then you can buy the correct turbo for your setup.

[Piggy]

you can buy a very decent turbo for a lot less than £300!!!! dont panic about that figure.


and fyi, not all gt20 turbos are vnt.

most on here us the 's' model which is wastegate controlled. simples

---

but a stage2 map, fmic and decent clutch will see massive gains without upgrading the blower!

[Heidi]

I know there is a waste gate model but iv read alot where the VNT setup with the GT20 was used, to reduce the lag... And £300 isn't bad for effectively a brand new turbo with upgrades its cheap. But you can always run second hand, reliability will always be a concern though as you don't know its past. At the end of the day he needs to specify what power he's after and where he wants it before people start telling him a definitive turbo to buy. No point fitting a GT20 if your after Sub 150 BHP.

[Poodle]

£300 is a good deal for a hybrid turbo, but it'll be struggling if you want to go much past the fmic install. As a reliability upgrade i'd say it's perfect, for further development it's pretty useless tbh. K03s hybrid is pretty much the same thing, hybriding will always be a compromise and for the sake of a little research a standard turbo from another vehicle adapted to fit will be much better. Spend the £100 buying a turbo that suits your needs and then £200 having it rebuilt, same price much better result.

Totally disagree. The newer GT turbos spool so quickly they make a massive difference to driveability. It's not all about headline bhp, the GT20xxS's spool so damned quick that the lag isn't really an issue, yes a VNT has instant boost but the wastegated ones are not to be looked upon as the same as older T25's and TD04's. I'm hitting full boost just over 2krpm, WAY quicker than the T2 I had before.

The GT2056S I use could theoretically run up to 190bhp all day long if the rest of the engine holds together. I'm still on a 9mm pump though (yeah yeah, XUD) and while it's not much more powerful than the T2, the chronic spool times compared to factory turbos makes it all worth it.

Oh and FYI a GT2056S can be picked up for sub-£150 if you hunt hard enough, a GT2052S possibly even cheaper. Completely transforms the way the car drives. Plus it'll produce less heat and will be miles more efficient than a factory blower. Might be overkill on a standard, unmapped car but totally worth it if you want to run stage 1+

[Piggy]

^^^^ agree all the way.
for the huge headache of vnt setup...a gt2056s would do the job very well.

I picked up a gt2056s with almost no play at all, but oil seal gone, for £120.

Im rebuilding with a garrett kit. Job done

[brock hdi]

I know for a gt2052v off a Nissan patrol wood that do the job

[silverzx]

If reliability is a major concern then I wouldn't go further then a stage 1.

If your happy to change a clutch then go stage 2.

Otherwise as with most old 306 DERV's things will go wrong when you start pushing them!

On the other hand, many of us have had minimal problems, if your kind to your car then it's not so bad but I get a feeling a lot of members on here actually try to kill their cars.

[Dum-Dum]

IMO people need to stop copying the one or 2 people who have found an adequate turbo and just have a look around and do some research. The amount of info out there on the internet is phenomenal.

Don't know why fewer people aren't running GT22 series blowers.


If you want cheap just go on ebay and look at the 99p turbos, there's alot of miss spelled listings that are bargains. You want anything off a standard diesel that makes 110bhp+ or anything modern with a capacity of 2.5L+

Probably because of the bigger hotside on the GT22xxS blowers, with a VNT yeah fair enough it will outweigh the delayed response of a wastegated GT22xx but the potential for more top end isn't really worth it unless you're aiming for siily power. Like I said, the GT2056S can more than likely flow enough for 190+bhp and still be within its efficiency band.

Nothing wrong with people copying though, not everyone knows how to read a map or hunt for a turbo (look at Flynn's recent mishap for that..). It's like the TD04 elitism all over again, there's no secrets when it comes to turbos. Who gives a f*ck if everyone has the same turbo if it's a setup that actually works?

I went through a lot of heartbreak and even more money trying to get my setup to work. I don't think everyone has the commitment/time/money to do something similar with a turbo that's been untried before. Some people just want to be able to bolt stuff on and know it works. Who gives a f*ck if someone tells you how to tune the car if you're happy with the end result? I have no issues recommending the turbo I use, and i'm more than helpful in making sure people don't make the same mistakes I did. If there was someone who was experienced in that turbo before me who could have held my hand and saved me £450 on extra turbos then great, but there wasn't any specific advice for MY setup.

It's for this exact reason the diesel tuning world pisses me off, everything's made out to be such a closely guarded secret. The petrol world, you can ask anybody anything and they'll share the info. 99% of GTi6's seem to run a Magnex exhaust and a K&N or Viper. Why don't THEY try something different?

Answer: Because it doesn't matter AT ALL.

If someone wants exclusivity, stop telling everyone what turbo they're using and let the numbers do the talking...

Chris thats not entirely the point I was making

[cwspellowe]

I know, i don't know what came over me

I was doing so well in the first paragraph to stay on topic too..

[Dum-Dum]

No worries dude, Its not a dig or trying to be exclusive its just I find all this turbo copying a bit tedious as it seems to run in 6 month/1y year cycles. Someone finds a turbo thats better than the last big thing, everyone else copys it for a while till someone else finds something better then everyone else copys that. I just find it all a bit unimaginative as I don't think anyone has found the perfect turbo for the HDi yet.

Id love to see a GT2060 bolted on as i think that would be epic

Yeah it's just a case of finding a GTBxx60 and nicking the compressor wheel. Same shaft size, would need the GTB housing too though. Can pick up 60mm compressor wheels from rebuild companies but would need it VSR'd and a properly reamed housing, wouldn't trust it without those two things knowing how fragile the GT20's can be. Would have some chronic surge though I think..

I know what you mean about turbo's though. But the TD04 still seems to be king because it's so f*cking cheap. GT blowers are still a tad on the pricey side for anyone who isn't prepared to put the effort in to fit one. Shame though as they completely transform the cars.

[Dum-Dum]

Lots of 2260s on ebay from about £200 for the parts you need

[cwspellowe]

Are they wastegated or VNT'd though?

[Poodle]

You can get wg 2260, but you'll find the hotside is too big for the HDis unless you extend the rev range, otherwise the gear ratios will drop you way off boost every time you change up. Plus you'll be needing some serious fuelling to make it worth the upgrade, beyond anything we've seen yet for sure.

Also, bear in mind the 2056s will make more power on a HDi than on a XUD, i'd be surprised to see it causing a restriction before 220.

It's not so much a restriction, 220 would be overspeeding it a fair bit, bear in mind I killed one on a 9mm. 190bhp is a realistic target with one though.

The 2260S has the same shaft as the 2056 too so would just be a case of bodging the 2056 turbine and hotside onto the 2250 compressor/CHRA. IIRC from stripping mine down, all the parts are individually balanced, so you may even get away with not VSR'ing it.
