While I am quite happy with the pull in my TDi, I feel that it could do with more past the illegal motorway speed mark.

So far it has been re-mapped and has a Merc MAF. I have heard that a K and N panel filter may be worth fitting too. However, despite its estimated 140bhp, I wander if there are any more reasonable mods that could be done to further boost the power? I am not wanting to do nitrous or anything extreme either.

The car is an ace workhorse, cheap to buy run, reliable, nippy and reasonable on fuel. I just wish it had a bit more pull past 70 mph so that passing people who put the foot down is less of a problem.

Any help/advice welcomed. []

Bigger injectors.

Amar put them on his 110tdi, could have a word with him.

Wouldn't bother with the K&N filter, minimal power increase vs. risk of oil contamination on the airflow meter.

Larger injectors is probably the last "easy" change, although you may want to try an original airflow meter in place of the mercedes item - they tend not to get along too well with chipped engines.

Also, have you had the dynamic injection timing checked? Worth looking at, and if possible set up to be slightly advanced, but still within spec. On a 110, an hour's work to do, with the right kit.

An ITG replacement air filter would be OK as I believe they don't need oiling so won't much up the MAF.

The engine you have is capable of getting close to 200 bhp although you would need to change the injectors, turbo and intercooler to get near that. VW had a race car based on the 110 engine producing around 200 ponies.

Not sure how viable it is to use the PD150 turbo and intercooler with a set of larger injectors. There is an old post that lists the part numbers for the injectors.

I think you can use the 130 turbo but you have to change the manifold to stick the 150 turbo on there.

 

[djhorace]

Thanks for all the input so far.

Am interested in going ahead with some mods but would have no clue where to start. Is there a web page or any information on doing any of the things suggested ie;

Bigger Turbo and Intercooler

New Injectors

Also, are there any suggestions for air intake?

Am interested in what shtu said about the Merc MAF. I put on the Merc MAF due to hearing so many issues with the VAG unit and given that my one gave up the ghost too, after trawling the forums, found that the Merc was the recommended unit. And given that it was half the price of the VAG one, and that response was ace after installation, assumed it was ok. Have there been problems with Merc MAF's and tuned engines? The only thing I an see wrong with mine is that the car leaves a huge cloud of black smoke in its wake under full accelaration.

Any further input appreciated folks. I will try to find the info on the injectors.

Cheers []

PM Amar, he is looking to push 200bhp

anything is possible, and like simon mentioned, it has been done before!

get a carbonio - as for the airflow debate, if they are going to die, they would die even in stock form!

 

[shtu]

Well, let's put it this way.

I bought Foxy's mercedes one, after he tried it on his car and didn't like it. Works grand on my std. 110. There's been a few folk complain of getting check engine lights and odd behaviour. Have a search...

As for the cloud of black smoke, maybe just soot getting blown out after trundling about for ages, or could just be needing the timing tweaked. Worth checking.

I'd go for the injectors first, myself. An hour's easy work with a set of spanners. For more info on tuning the non-pd, try www.tdiclub.com They are much more into this, as the non-pd was the only US engine until very recently.

Off top of head, injectors are from transporter van. Part nos. are on here somewhere.

 

[LiQuOrIcE]

my 110 is standard with merc maf, pulls very very well upto 90, sitting at 70 and put foot down is no problem.

 

[Jotape]

I've a friend with a 110tdi with 224bhp...

remap..bigger turbo..bigger intercooler..uprated clutch..injectors...and a more couple of things....

So...it's possible.

 

[Rivage]

I've just spoken to Jabba.

If you have a remap/ chip/ whatever, the car will have to be reverted to standard before tuning with bigger injectors begins.

Just chucking on the injectors without re modifying the ECU map will result in horrendous overfuelling.

Once the car is back to standard, you can begin playing once again. As people have said, injectors, turbo, intercooler, exhaust etc etc etc (clutch, gearbox) can then be changed and the car will need a custom re map.

Power up to 200bhp ++ is possible.

the turbo only has internal differences, they are both physically the same and in size, ive compared them.

i thought the con rods needed to be upgraded for the older TDI to be pushing 200bhp? ive heard stories of bent con rods.

Just spoke to Simon at CentralVWAudi, http://www.centralvwaudi.com/

and he was very helpful and explained the options available for my engine and diagnosed the judder I am experiencing through my clutch.

FYI, a 110bhp unit can, as has been mentioned previously, have Injectors added from a 2.5 VW Transporter (am still looking for the Bosch part numbers on the web), but because this particular engine was not found in transporters in the UK, Bosch stopped selling them and they can only be had through VW stealers now for ?400 a set.

A TDi 130 turbo can also be added for a further bit of power. With a re-map from Superchips (Recommended by Central) power and torque should be up by around 50% from standard with 170 bhp being a likely figure.

Central did however say that the injectors could be added to the current configuration with no real problem. Overfuelling may occur at low revs but the turbo will go to higher boost levels when it the ECU detects more fuel. However the transporter injectors do not inject at the same low level as the standard units.

FYI, also, according to Central, the TDi 110 Passat clutch can be changed for a clutch from a Passat TDi 130 (5speed) from a 2000 model early facelift Passat before they changed to 6 speed. A juddering felt at low revs on full power is the dual mass fly wheel complaining about too much power. And something else I never knew was that the MKIV golf has a different, more advanced, ECU to the Passats 8 bit jobby making the Passat less tunable.

All in however, the engines are the same, and if you have a TDi 110, it may certainly be worth speaking to the chaps as I did.

Now to find the transporter part numbers, and hopefully a supplier that will do them for less than ?400! And a turbo from a 130 tdi, or 150 tdi with intercooler and manifold, a 130 clutch...[8D]

 

[djhorace]

Oh, and forgot to say he has a tdi 90 (golf I think) with 240 bhp which does a 13.03 1/4 mile!!

hope it helps!

For the 90hp 4-cyl 5 speed injectors (known as 0.184 injectors) here are the part numbers you'll need (upgrade for automatics in North America only):

(Qty 3) - 028 130 202 P (there may be a suffix on the end indicating that it is reconditioned)

(Qty 1) - 028 130 202 Q (there may be a suffix on the end indicating that it is reconditioned)

For the 110hp 4-cyl injectors (known as 0.205 injectors) here are the part numbers you'll need:

(Qty 3) - 028 130 201 T (there may be a suffix on the end indicating that it is reconditioned)

(Qty 1) - 028 130 201 S (there may be a suffix on the end indicating that it is reconditioned)

For the 150hp 5-cyl T4 Multivan injectors (known as 0.216 injectors - biggest commercially available) here are the part numbers you'll need:

(Qty 3) - 074 130 201 K (possibly with a V on the end indicating reconditioned rather than new)

(Qty 1) - 074 130 202 R (possibly with V on the end)

Yep, Just went through that part of their web page. Must have missed it first time round.

Looks like they recommend going to standard before adding injectors. I was under the impression injectors would be plug and play with my mods..??!

Lots of information on that site though. Worth a visit.

 

[bobseptic]

These .216 injectors sound the ticket, i will start looking tomorrow. As for remapping to standard im sure the chap who did my remap will have some ideas. Plug and play sounds good though.

My original remap is backed up so i dont see a problem.

I know i havent seen the dyno figures but the bloke who did my remap said he regularly gets the 110(non pd) up to around 170 and has even brought a 100 up to 170 with no adverse smoke/comsumption. I cant wait to see the figures. Would this mean maybe the injectors in the 110 have the ability to get this 170 figure.

By the way this bloke drives a 130pd @ 240 with remap/aftermarket intercooler & hybrid turbo + Boost guage. I havent seen the dyno figures with my own eyes but when i do i will post shots [!]

But i tell you one thing pinkys_pd130 goes like f***dabbydosey. Ive never been in a diesal that pulls that way.

Don't know if these http://forums.tdiclub.com/showflat.php?Cat=&Number=139346&page=0&view=collapsed&sb=5&o=7&fpart=all&vc=1 race pipes ever made it into production.

Might get a few extra ponies with one.

 

[djhorace]

Does anyone know of a VAGCOM machine in the North East of Scotland in a garage that know about TDI engines and are willing to set up a non standard TDi?

We have wannabe garages here but dont fancy using my car as their test bed as I have heard of some expensive horror stories!

 

[djhorace]

CentralVWAudi will sell you the injectors for ?400. Apparantely they are very hard to source now however. Everything I have read and heard is that the injectors are probably better than a re-map/chip from standard.

You have an ideal setup bobseptic if your original setup is stored. If you add injectors in standard ecu form you will be able to compare std injectors and chip and std chip and .216 injectors.

I think I will have to change my injectors at a location where I can have the car re-mapped or at the very least, have someone who has a vagcom and knows about TDi engines. Central reckon I could add the injectors as is, but that goes somewhat contrary to what the TDiclub says. In order that I try to prevent huge repair bill think I will go this route.

Perhaps if there is enough interest we could do a group buy on .216 injectors?
