TDCi upgrades?

[poormansporsche]

I know what you are saying mate, I only went down the boost controller route because id already had a remap and the remapper told me that the boost was fixed and not ECU controlled, so although the fuelling had been upped in my limited understanding of these things it only seems like half of whats possible ! On my old passat petrol turbo when it was remapped the boost was only upped by 20% but this really made the big difference. I wasnt hoping for marvels by fitting the boost controller - just a bit more of a "Kick"

Anyway took the mechanic out in the van today with the boost controller on and let him feel the jerkyness and his first thought was that the injectors are maxed out

bigger injectors off a focus 115bhp ?

[mattvik30]

so is it not running smooth at all? Can you feel a big difference with the extra boost? Im really interested in knowing if the focus 115ps injectors will fit.

I remember when i joined this forum nowone was really doing anything to there vans and it was mainly a forum for problems with the connect. Now these vans are really getted tested perormance wise and we seem to be finding a way around there not being any aftermarket parts for the connect keep it up! we will get 180bhp out of these vans yet!!!!

It's only recently that folk have found out how to really push the T4 engines - and/or what can be sourced off other stuff to fit.

I guess the Connect will follow suit soon enough....

[mattvik30]

I think give it a few years and companies will start making aftermarket parts for the connect, as the van seems to just get more popular as time passes.

dunno whether its a big difference just more of a kick not a smooth delivery as you can hardly feel the turbo in standard form

it would be helpful if anyone knows what brand the injectors are ie bosch or delphi or something

If anyone can get these details, I'll have a dig around with a friend of mine who's done a LOT of work with injectors on the T4.

To give you an idea, he pioneered the work that gets an 88 or 102bhp 2.5tdi up to 150bhp+ - with injectors accounting for a big chunk of that increase.....

It may also be that the fuel pump needs uprating ! what i may do is just buy a tuning box and bung that on and experiment with extra fuel as you never know even with my remap it still might not be getting enough ! Dunno if its a bad idea though remap and tuning box

You done a de cat yet poormans? may help a little?

Also I personally wouldnt have the valve on, would just be using the gauge to check your never loosing any boost.

Think them bigger injectors and back on the computer would be a better job, but a pricey one! Thats if that would work?

maybe an email to vantuner about this to see if it cold work??

[NikFrisbee]

Maybe sent the injectors off to desiel bob, i think he can make them larger, but no 100% sure?? Injectors are exspensive so needed to be right. I think i have a PDF file will details of ford engines/models/injectors/codes and a PDF file how to find out what your injectors are and firing order etc. If i can find it i will upload, but not sure how to on this forum??? Also the injectors have to be coded to match to the ecu, but i think this can be changed with software..not to sure thou as this is somethink i have been reading up on the past week to see whats what. I think if this nut can be cracked then with a decat and remap we should see gains. But as be said before on this forum, turbo, intercooler,etc,etc need balancing, but i think with enough of us willing to try who knows what possible...

[poormansporsche]

pain in the butt if the injectors need to be coded as its a bloody fortune from fords to get done, oh well least the injectors seem a bit more reliable than the 2ltr tdci ones which are always going wrong, my local scrappy has a diesel focus on the pile, will have to climb up and have a look what engine it is and if the injectors and fuel pump are still there

[stephenferguson]

You could send ure turbo off and get it machined out a bit and a bigger compressor wheel put on, will help it high end. ha it done to my defender.

Also the air intake on these turbos is way too small, i have been told that if this is made this bigger it would help. And you would notice the difference, mite do it to mine.

Any details of this company?

Had my van mapped by martyn yestaday, was well worth the 400 mile round trip. Top bloke Anyway he said to go any further with power to go down the hybrid turbo and bigger focus injector route.

[poormansporsche]

can we just confirm though before i go salvaging from different motors that the only difference with the 110 connect is the turbo ? does it have the same injectors and fuel pump ? Also another thing that also may need upgrading is the fuel rail as well as ive heard that some rails have a limited capacity !

[So-Kal]

OK - the guy I'm asking about injector upgrades could do with some info (that I don't have) - so can anyone give me details of engine codes of the 75PS and 90PS, along with any other details that they may have - ie injector manufacturer, whether they're coded, etc....

ANy ifo appreciated so he can go digging......
