injectors from a 110 bhp leon or tolly

[leon1918]

can i fit these straight on to a 90 bhp leon and c an increase? do i also need a remap or chip??? i have been told i could see 130bhp+ from this mod??

You will not see 130+Hp from that change, I seriously dought you'll get 110 with those changes alone.

IIRC you'll need ECU adaptations to get it to work, but that's about it.

[markmck]

you will get more power but you may get more smoke.

eith a chip you'll need to make sure that they know its not a 90 std as the bigger injectors will flow more fuel giving more smoke


look at www.kermatdi.com for more info on injectors

[leon1918]

just off the phone with superchips(buckingham ind est) , they say the injectors are basically takin my car from a std 90 to a std 110 , he seemed to know wot he was on about , would this not mean that after fitting these injectors and then serial programming ,a air filter upgrade i may c the increase that a 110 could or near abouts?? i have a mate who has the 110 tdi leon an side beside up until 70/80 we have not a lot between us , both tuning boxes , then he can pull away from me and take it eay in a line . to have similar power or more would have me grinning from ear to ear with the standard tdi badge on the rear.

I'm trying to get a local Upsolute Group Buy thing with Simon Coe

www.upsolute.com so drop him an email if you're interested.


Cheers

No
The difference between the 110 & the 90 isn't only injectors, it's turbo, exhaust manifold, completely different mappings among other things. If you swap the injectors and remap/chip, the remap/chip will need to know it's a 90 running with 110 injectors (for added fueling). You still won't be able to get the 140-150 ala 110tdi.

[leon1918]

cheers prc, sound advice , would u think its worth doin this mod since i have sourced the injectors for £70???

[prc]

I deffo think it's worth doing, you just need to work the added fueling with some added boost. You might be able to get close to 130 with a good remap (aka a good amount of boost) + injectors.

Responded to your pm BTW.

[leon1918]

i mjst be annoyin the nuts off u guys but this stuff is addictive , i am readin about powerplus 520 nozzles , costing 280 usd, i can get the 110 ones here for 70 £ , wouls they do the same job or is there much difference? , would the upsolute chip be better than getting the car serial programmed over here after new nozzles?

[leon1918]

mark , after the 110 injectors are bought does that mean that the 110 chip from upsolute would be suitable???

[markmck]

the ecu between the 90 and the 110 are different so you would need a special remap for chip plus injectors

doesn't really matter with its serial port tuned, chipped as long as the mapping factors in the injectors.

Where were you thinking of getting the serial port remap done ?


there are a number of options for remaps / chips but not all are available for the older TDI's: Revo - they have code for the 110 but ofor certain ecu's, jabbasport can do a standard or custom remap, upsolute - not sure if they have anything to work with biiger injectors thought plenty of guys on tdiclub have this setup

you've also got AMD, APR plus I know of another guy who has a motorsport developments chip


Beware that you can have too much torque on these cars as the clutches can slip and the flywheel oscillate depending on the output


One upgrade leads to another........

[leon1918]

i hear car toys can do the serial port programming , for about 350£, take it u know quite a bit about diesels?? as u can c im totally new to this but want more poke from the 90 , was considering a change to a 110 but to find a clean silver 110 was amazingly difficult to start with an i think the tolly is slightly 2 big 4 me just yet! i get enough stick for the diesel as it is , but i really like the leon and thionk she will lokk well after a bit! have u got msn , it would be good to speak to u about this stuff cos u seem to know where ur comin from

I don't have any first hand experience of puting any of this into practice ona a diesel yet but as my Tolly has just gone out of warranty so i've got an MS Design front grill plus a set of Koni Sports both still in the boxes and waiting for install.


I am looking for a good set of springs for Tolly but haven't made up my mind yet


Eibach do a set of -30mm which are linear
Pi do s et of -30 which are progressive and
Spax do a set of -30 which are progressive

The eibachs are +25% uprated over standard. the others I don't know.

I think I have MSN but haven't used it for ages as i can't remember the password

Best thing to do before you do any mods is find out all the info you can before hand so that you don't get any nasty surprises

[leon1918]

i am currently running eibach springs alone ( shocks coming soon) but i have to say thye handle a hell of a lot better than std , they are 50mm which u may think would be too much but its really not bad at all , as i work in michelin i too have 8" *17 pilots which also help to keep me on the road! , will ask aroundabout tuning, i dunno if u know any of these other lads ,i hear from a mte melvin mc alonan whop drives a red 150 golf that a local guy does the serial programming cheapoer than most , supposed to be quite a job as seen on the m2 in a 110 golf sittin not wile far from the 150!!!!

We can tweak the files for any significant mod that you do to your car to get the most out of it. If you run your 90 with .205 injectors you will for sure see more smoke and so if you have the car chipped the inject quanity will need to be reduced to prevent excessive smoking. We wouldn't take the boost any higher than the standard file for the .184 injectors for fear of reducing the longevity of the turbo though. I think that the price you have been quoted for these injectors seems pretty good and might be worth it.
I would think that the above with a decent air filter might get you to around 125-130bhp with maybe a bit of smoke under WOT though. Always good for p1ssing off the tailgaters though :D
The turbo's on the 90 and 110 are quite different though, so you will come up a little short of the 110's chipped numbers

[leon1918]

maybe im missing sumthing here but if i fit bigger injectors from a 110 an then reduce the quantity injected isnt that defeating the purpose , wot sorta price we talkin for u to have me running at 125/130 then after the injectors??? i take it my tuning box needs to go?? cheers

[markmck]

welcome to the party Simon.....

How are we progressing on the NI Group Buy?


I've been tryin' to get interested parties to contact you direct so that you have a better idea of numbers.

Anyway looks like Leon1918 is another for the list !!

From my reading of this on TDIclub you need VAGcom to change the IQ (reported to the ecu) to keep smoke down.

Too much fuel with not enough boost = smoke - unburnt fuel.

problem with extra boost is the your turbo can only handle this up to a limit then melt down

basically by cahning the IQ reported this enables the ecu to compensate for the bigger injectors so reducing smoke


PS. Do you get cheap tyres from Michelin by working there ?


Maybe you could get a seatcupra.net discount organised !!!:D :D

[UPsolute]

1 hour ago I told myself that I'd take a quick 5 minute look at the forum and I'm still bloody here !!!
In a way you could say that it's defeating the object, but on the other hand it stops you running too high a temperature which wouldn't be good and also stops you getting pulled by the old bill for polluting the planet ! There's a point at which throwing more fuel in will do nothing but create loads of soot, which is basically poorly burnt fuel by the inject staying open too long on the down stroke.
I have actually tuned a 110 running .216 injectors without having to really reduce the inject, but believe me with your larger injectors it would need doing !!
I wouldn't advise messing with the IQ using VAGCOM, unless you're confident you can return everything back in case it doesn't work out !
You will not be able to use your TB with a chip and it's likely that running a TB with larger injectors would make it smoke a lot also.
Price wise it's no more for 'tweaked' files than it is for a standard set up.
Mark, I've been sending some mails tonight, we'll speak at the w/e on the mail and see where we're at yeah ?
I'm seriously turning this damn computer off now !
