hi. im looking to change my injector nozzles to .216 and get a remap aswell as upgrade the clutch to a performance single mass kit to deal with the extra power.

im in devon does anyone know who can remap the car properly? as i am changing the nozzles it will need a custom map and most places just seem to use a generic map thats used on all.

anyone else done these mods and how has it affected the car? bhp and torgue wise?

should i upgrade the suspension and brakes?

my leon is the sx model which has slightly more stiffer suspension to the 110 s.e's i have been in.

unsure about the remap part, but if you're going to make your car faster, then of course you should upgrade the brakes at the very least...

i had a golf gt tdi 110 remap by morebhp.com guy called jason top block , i would suspect incresing the nozzle sizes on the standard will require custom mapping to make the air fuel ratio just right, if its a pre 2000 car you might the ecu on the bench to do so, i made 142bhp on a genric stage 1 map 100% oem hardware, so i wuold think you can make close to 150 maybe with turboback slighty more

yeh. i might just wait for the current discs and pads to be used up before changing but when i do i will put some ebc or mintex uprated stuff on. i dont drive the car that hard just want some more 60/70 mph plus grunt for the motorway.
its a 2003 car so should just need a plug in remap.

think i will ring up some vw specialists that are about that remap and see if they can do a proper dyno test and map.

what about blocking off the egr valve? did that to a vw i had and made it much more responsive... anyone done it to one of these asv engines?

Yeh nozzles and map will get you upto the 150 mark, I've sent you a pm with the email addres of a guy who can sort you out, he's running his caddy van at 157bhp, he can also supply the G60 flywheel and sachs VR6 clutches.:)

thanks for that, sent him a message, i shall wait a reply.

does mileage on these engines affect them much when it comes to tuning.

i have tuned many petrol engines and i do know my stuff but my leon has done quite allot of miles.

its never missed a service and its always used top oils and runs better than many cars i have seen with half the mileage. the turbo is good and shows no play and isnt very old. it doesn't smoke or make any odd noises. doesn't use any oil between services
generally it seems to be a good healthy unit and has been used for motorway miles cruising at around 2300 rpm never been ragged at all.

i have a friend with a pd engine thats remapped to 190bhp with over 200k on and he raggs it everywhere and it still goes strong and healthy

are there any components known for wearing out on these? i can rebuild engines so i can replace bits if need be.
as with most things it tends to be not how many miles but how they have done them!

They're pretty tough engines, especially the older ones, thrash them loads and they still run sweet. Just make sure the oil changes etc are kept up to date and always let the engine warm up properly, there's loads of them in the states with huge milages and big tunes.:)

i think if you go up to the 216 nozzles then you will have to adjust the idle as it will hunt and the fuel mixture will be all over the place. if its a non pd which i supect it is then you will have to do "the hammer mod" google it, its self explanatory. best place to find out about modding the diesels is tdi forum and the best of the best is a guy called kermatdi, very very knowledgable on these cars, my brother has had a generic remap put on his car ( Golf gt tdi) AHF engine and hes running a drilled airbox with cold air feed and smoothed internals of the airbox and it flies!
I ordered a mercedes MAF for him so will fit that and see how much beter it runs. keep us updated with your progress, and as for the egr delete, i did that too for him after cleaning out his egr valve which was absolutely caked in gunge, i then blanked it off and disconnected the solenoid for the egr. ran much much better.

He wont need the hammer mod with a tune though, only if he's using the nozzles alone like me. I agree about kerma though, that's who I got my nozzles from and drivbiwire fitted them and set them up, very impresed and loving them. Does your brother have the engine light on after the egr delete? I've turned mine down to nothing but am thinking of doing away with it all together, what's with the maf? What's the advantage of the merc one?:)

his is a 1998 golf so i dont think they threw the light up, you can get that mapped out anyway so the light doesnt come on, apparently the merc mafs make the engine more responsive, have you got a link for the nozzles and balancing?where did he set them up when he fitted them? just blank your egr off and pull off the connector for the egr solenoid. where is this guy based who set the nozzles up on your car?

yeh the hammer mod seems a bit invasive of the diesel pump which even the tiniest particle can play havoc with.

i might make up a egr blank plate at work and see what it does.

dash light wise, i know someone who has got a pdtdi 02 audi a4 and that doesnt put the light on, just leave the hose attached so it can get a vacuum.

The hammer mod is fine but there's no point unless really needed, after fitting my nozzles my iq is at 5.5 anyway and if anything I could do with reducing it down a little bit, the lower the number the higher the actual amount that gets injected. Is that the tdi club you've joined?

I sent a set of injectors to kerma and he passed them to his mate drivbi as he does all the fitting and balancing, then they got shipped back to me and I installed them on the car.:)

yeh tdiforum

did you use new nozzles?

do they need to be set up then? not a simple take the old ones off and fit new.

what sort of money would i be looking at to get them fitted and balanced?
do kerma and drivbi have businesses in the industry? as i would be a bit worried about sending some expensive injectors and nozzles off to them if i might not have them back. and my car will be off the road in the meantime.
did you get new injectors too?

The ones in my sig "Bosio PP764 nozzles" They're good for 180 bhp with the right mods and also have a 5 year warranty.

I got a set off an old passat from the scrappy and sent them off so I could use my car in the meantime, the ones from a 1Z, AHU, AFN, ALH, AGR etc are all the same bodies. It cost about £280 all in including the nozzles ,the fitting, balancing and postage.:)
