All I know there were 'ARL' injectors installed. I will try to find out whether the BIP map was adjusted.
-
The car drives OK, no real (extra) vibration during 'normal' use that I can discern. Only issue is that sometimes, when the engine is idling in stationary mode, the cadence goes to a 2-step hop-hop rhythm; a little accelerator fixes that. Also (de)clutch sometimes helps. Can a 4-pot flywheel be machined towards 3-pot-ness? (adding versus subtracting material) If the only issue is the one I described, then is it worth doing so w.r.t. saving the engine?
-
Thanks, I acquired the bearings. Later this year I'll obtain the diff and find a place to have it fitted.
-
Does anybody here have access to info with the part number of the (conical) bearings at either side of the differential in a GRJ gearbox? As these should be not too expensive, I'd replace them when the diff goes in.
-
Yes, chipping is quick and has nice effects, but a GTD1752 turbo can really make the 1.4 TDI shine. A visit to the folks at http://das6-gang-getriebe.de/ can reduce RPMs and/or increase speed somewhat. The issues you mention are mostly due to age, I guess.

Sometimes it does spin in 3rd yes. So I did some research: At the quaife website I found: https://www.quaife.co.uk/quaife-atb-limited-slip-differential-launched-vag-cars-using-02j-b-transmission/ and https://shop.quaife.co.uk/audi-a3-02j-quaife-atb-helical-lsd-differential-1257 This means we need their number QDF26R for the GRJ gearbox. With that info I find this local supplier: https://www.motorsportparts.nl/volkswagen/golf-v/aandrijving-en-diff/Quaife-torsen-sper-VW-Polo-Golf-Mk5-02J-B,-02R,-02S-6-speed-2004+-c-w-bolt-kit- for a kit of diff and bolts. Requires about a day of work to be fitted.

Some flexible elbows/joints were replaced due to leaks that had developed. Tune was adjusted slightly. 170 HP. Same NM if I recall correctly. Fox feels like a new car again, accelerates harder than before. (will get timings in spring!)
-
Why? Every project is different and pricing like https://www.vanvughttuning.nl/chiptuning/prijzen/ just tells some benchmarks. I explained some extra work (besides the power enhancements). I guess you can do the math. On Facebook, when VVT posted about the car, some people said it was a waste of money. (i.e. to invest in a car with low resale value) They do not understand the situation of a rust free chassis, an engine that runs well and a car that fits the user.

VVT put he car on their website: https://www.vanvughttuning.nl/listings/vw-fox-1-4-tdi-160-pk/ Car is running fine. Now has the ARL head bolts, new pistons and rod bearings (because of miniscule crack). Also a full stainless 2.5" exhaust was fitted. (made response a tiny bit quicker) ~160 KM/h at less than 3000 RPM is kinda nice. (original car does 120 KM/h on the GPS at roughly 3000 RPM)

The `reference` Lupo with 200+ HP has injectors with bigger holes. This setup has some issues at idle which I'd like to avoid. Currently more power is not really needed. I simply need to find out how quick the car currently is. VVT fitted a 4pot flywheel, this was necessary to make the 400NM clutch setup fit. I am not aware of gearbox (`GRJ`) chatter; I do notice a small idle issue where the 'roudness' of the engine's rhythm can go to a two-step rhythm. A little throttle fixes this. A 1.9 engine will not have this issue I guess.
-
I guess that info needs not to be shared openly. Think about a gen five turbo. Think about a custom downpipe. Think about the custom FMIC piping. Think about a 450Nm clutch and flywheel for 4-cylinder engine (required to make clutch work). Think about bigger brakes in the front on `fresh` fusees to allow the bigger size brakes. Think about the VNT converted (not A2) firmware for the ECU and the tune itself. Think about two weeks of work.
-
Dunno about boost figures. Where can I find out about them? Would my UltraGuage be able to display boost pressure? Pics can be found in VVT's fakebook. FMIC was installed. Custom downpipe was installed.

Nicht bestimmt, aber ich glaube dass ein A2-Anlasser verwendet wurde.

After one week of mostly calm, quiet driving I can say that fuel consumption remains largely unchanged. Next week we'll drive a tiny bit quicker to see the impact on fuel consumption.
