Introducing PP0.5 – The new PP2 Injector.

Dear all, As you know we pride ourselves on producing only the best modified injectors for our valued customers.

Well, we’ve done it again and this time, we have developed a mod which is probably the most versatile and accessible injector mod that we have done to date, and for some reason, I have called it PP0.5, The results from these injectors are highly positive and they are a welcome addition to our line of injectors.

As some may know, we were producing a modified Stanadyne injector aimed at the 88 bhp T4 that we called the PP2 injector. These injectors were old hat single stage stanadyne ones which as standard units, perform fairly miserably. Once modified, they were able to deliver up to 140 bhp upon remap. The problem with the stanadyne injector is that out of every set we receive, only 2 nozzles can be unblocked sufficiently well enough to use, combined with the fact that the needle lift sensors are againg and failing more often, another solution was required.

Initially we offered VW T4 PP1 injectors as a better alternative to the stanadyne PP2’s, which they still are and they are still offered, and still deliver in the region of 150bhp once remapped.

We have now developed another alternative to both PP1 and PP2 primarily geared towards the 88 bhp AJT engine but also of use on the 102 bhp ACV engine. These are the aforementioned PP0.5 Injectors.

So, what’s different about these ?

Firstly, they are Bosch injectors. That means that they are 2 stage injectors that perform much better than the single stage stanadyne injectors or even PP2 modified stanadyne injectors for that matter.

Secondly, they do not require a remap and will deliver around 125 bhp on upon installation and the option to remap for even more power either soon or at a later date or is still present.

Thirdly, Emissions – PP0.5 Injectors flow fuel differently to PP1, and as such the emissions from these are minimal and this is one of the reasons that they don’t require a remap in order to be used.
What are the benefits to fitting PP0.5 Injectors?

PP0.5 Injectors open up a whole new range of possibilities for both the 102 and 88 bhp T4’s.
For the 102 bhp T4’s (And 1.9TDI Engines) – Vehicles produced before 2000 had the older type ECU which requires the chip to be replaced before a remap is possible. There are only a handful of places that cater to this so by fitting PP0.5 the 102 can enjoy a substantial performance improvement without the need for a remap.

Performance & Economy – Although PP1 are the classic injector upgrade for the VW T4 102 bhp, PP0.5 can offer a veritable middle of the road option which might appeal to certain owners. They will deliver a great balance of performance and economy and should yield around 125 bhp by installing them. Economy generally improves as a result.
Cost – for those on a tighter budget who do not wish to remap immediately or at all, these injectors are a viable way of achieving a Project Power performance improvement without breaking the bank.

Replacement Injectors - In addition to a performance improvement PP0.5 injectors offer a viable and cost effective way of replacing worn or failed injectors with fully reconditioned ones which not only offer the benefits of new injectors at a fraction of the price, but also the improvement in performance. This is true of both the 102 ACV engine and the 88 AJT engine as the injectors can be used for either.
For the 88 bhp T4’s – All Models can utilize the PP0.5 Upgrade including those with the older and those with the newer type ECU’s.

Performance & Economy – On installation alone the PP0.5 will deliver around 125 bhp on a completely stock vehicle. Economy will either remain the same or improve. Generally it will improve as the engine has to work less to achieve a given RPM.

As with the 102 the option to remap for even more power will always be there and an intercooler can also be added at your leisure.

The main benefit for the 88 is the accessibility to this modification, it only requires the injectors and in some cases a minor adjustment to the idle which is effected with VAG COM or VCDS and literally takes 5 minutes.
We have now fitted these to quite a number of 88’s and the results have been consistent every time. A highly discernable improvement in performance to 125bhp, no smoke and great economy.

Cost – PP0.5 injectors are remarkably good value for money. With PP1 or PP2 a remap was required within a couple of months of fitting. With PP0.5 the remap can be left until such time as you want to do it. As such it can save the cost of the remap and cuts the cost of the performance upgrade to almost half.

A remap of course can be done at any time in the future and is recommended to give even better performance but is not a necessity.

Installation -

Installation of the injectors is relatively straight forward and instructions are given on request. For the 88 bhp engine a replacement fuel supply pipe is required as the wired or lift sensor injector on the Bosch set is slightly longer than the stanadyne. As such it should be installed in Cyl. 5 and the fuel supply pipe from an ACV engine used so that it reaches the injector perfectly.

Below is the Dyno run from Adam Oakley who has tested the injectors for smoke and power on his stock 2.5TDI
As you can see 124.5 bhp with 183 lbf-ft was achieved with no other modification.











UPDATE !!! UPDATE!!!******************************UPDATE!!

OK so its been a few years since we began making these VW T4 injectors and the feedback has been brilliant.

We have since learnt that these injectors are capable of a whopping 169 BHP !

One customer asked if we would supply him with one of our 2.5 inch downpipes to compliment his PP0.5 injectors, we said why bother ? they are the smaller nozzle and we didnt think it would be worth while.

The chap insisted and we sent him the downpipe and he then went for his remap. The mapper phoned me as he was very surprised too when the van made 169 BHP on the rolling road. The feedback from the mapper was that these injectors are the most versatile injectors he has worked with and deliver fuel in such a way that they can be used as a direct replacement for worn injectors or for performance mods so long as the diwnpipe was fitted.

So we now have the best solution possibe.

Without a remap they will make a nice modest 120 bhp or there abouts

With remap they can make 140 bhp

With our 2.5 inch downpipe, Exhaust and remap - 169 BHP.

Now you might ask what is so special about the 2.5 inch downpipe ? Well aside from its amazing quality and looks, it removes the most restrictive part of the exhaust tract - the cast iron exhaust elbow from the turbo and replaces it with a totally unrestricted apperture which makes a massive difference to the flow of exhaust gas.



Take a look at the old elbow next to the new apperture and it becomes clear.

Re: Introducing PP0.5 – The new PP2 Injector.

Good news, I`ve been thinking about giving my bus a bit of a boost in power. As an every day runner it`s fine but the issue lies when I need to overtake something on single A roads, that's when you really need some extra push.

Vans a 2003 2.5 Tdi 88 bhp AJT with around 200k on the clock. De-cat exhaust fitted along with the EGR replaced with Allard kit and blanked off. A little whitish smoke on start up cold but clean when up to temp. Not to fussed about a remap if I can run all day with this mod at 125 bhp, that's the best part of a 50% increase in power. On top of that I`m refitting the inside just now.

Could you let me know costs on here or PM me for future planning.

Cheers Wullie P

Re: Introducing PP0.5 – The new PP2 Injector.

As above, if you could give us a price and when these are available as my vans back in the garage next week and then it was planned for pp2 but now you've thrown these into the mix then the thought I could fit and forget would be awesome.

Re: Introducing PP0.5 – The new PP2 Injector.

Hi Rake,

Could I have a price on the new injectors too please? Mines a 2002 102 ACV.

If I were to have a subsequent remap after the injectors have been installed what would be the overall increase in BHP?

Thanks x
Hi Dayvan,

PM sent with pricing.

Regarding the bhp after remap I would estimate a 140 odd bhp van.

Re: Introducing PP0.5 – The new PP2 Injector.

hi Rake,

my bus is a 2002 88bhp & i was going to fit the pp2 so i'm glad you developed these. could you send me the fitting instructions so i can decide whether to fit myself or get them fitted also could i have a price on:

1) set of injectors and necessary items to fit supply only
2) injectors supplied alone
3) how much to do the complete job minus a remap
4) how much all in including a remap

also do you still take the old injectors in px

thanks T:

Hi Cader,

I'll send over the injector pricing via PM,

As for the remap - I don't do the remaps but can recommend some mappers to you.

Fitting is £130.

The fuel supply pipe from the ACV is £70 odd from TPS although I don't professionally advocate it, the existing pipe can be manipulated to reach if you fit the wired injector back in pot 4.

It has been done numerous times already with good results.

Kind regards

Ron.

Re: Introducing PP0.5 – The new PP2 Injector.

hi rake. can you PM me the price of 5 injectors for my 2003 AJT please, i can sort the rest T:

by the way, your diesel rhino stuff is awesome. i have been using it for about 8 months now religiously but a couple of weeks ago i found myself out of town, low on fuel and NO rhino on board. what a difference!!!! it sounded like someone had fitted a 1995 transit engine in there :eek:

Hi rotax,

Message sent as requested.

Thanks for the Rhino feedback too, it is always a pleasure to hear :)

As for the PP0.5 injectors - the results are great.
Everyone who has fitted them so far is saying very good things about them and are very pleased.

Kind regards.

Ron.

Re: Introducing PP0.5 – The new PP2 Injector.

Rake

I have the original PP injectors fitted to my AJT 2003 2.5TDI way back in 2008 with a remap and have been very pleased with the long term results. Is it worth upgrading to the new 0.5 injectors your offering or just stick with what I've got.

Re: Introducing PP0.5 – The new PP2 Injector.

Cheers all who have asked.

PM's replied to.

Some good feedback is appearing on facebook from those who have installed PP0.5 already.

Andy Brooks I have the PP0.5 injectors installed by Ron at Project Power a few weeks ago and can assure you all it is the best purchase I have made on my van. I now have the smile back on my face again and enjoy driving it. Right good fun to drive now, thanks Ron.
Rolling roaded my t4 2.5tdi got 124.5bhp at the wheels, stock bar decat, k&n, egr blank and pp0.5 injectors. It's a different beast now well pleased!!!
