Is it a little purple plug that is beneath (or above) the cigarette lighter?

Yup.

I think this will be beneficial to keep eh? lol

Double yup. ;D ;D

I noticed that on my two ten days driving the TDI around town and about 500kms roadtrip on the highway one day, that it doesn't smoke much. I mean obviously that tiny K03 spools low and keeps the fuel burning properly, and then the pump keeps the injection happening at the best possible time.. BUT I LIKE ME A BILLOWING DIESEL ;) Bigger Injectors are in my future, me thinks.

Obviously bigger inter-cooler piping will cause some lag, but is it even a problem with the quick spooling k03? intercooler piping will most likely need to be one off, and i was wondering on turbo lag, what do you think?

I was thinking of bigger intake (maf-turbo, turbo-ic, ic-intake) will this even be worth it for anywhere near stock power? Probably not eh, as they don't list an intake upgrade as even suggested till you add like 60 more hp though eh?

What range does the k03 do well in? Obviously its making its peak psi at 1900 where the engine has 150 ft/lbs.. how much does it go outside of its efficiency range at say 4000? Or higher?

I was under the impression from BrokeVW's site (which I can't seem to load right now :s) that the later 90mm 020 tranny flanges bolt to and in place of the 02A 100mm flanges..?

so that stock 90mm axles can be used..? anyone got anything on this?

dont trust me huh.. look at mods list.. myke_w ask him bout me..

for simple aspect.. look at bently tranny area.. no idea if 98 tdi book has tranny tear down info.. but if all else fails etka the axel flanges.. aka 020 vs 02a.. or go clean the grease from the 02a cup and see how there is no clip/anything in the cup..

you could always contact brokevw. He knows the 020 stuff and some about the 02A. He may know what works with what.

You can swap 90 and 100mm flanges between the 020 and 02A all day but make sure the axle lengths are right.

That does not sound right to me. The flanges don't interchange from 02O to 02A or the other way.
I'm running an 02J trans with 100mm TDI,2.0L gas car trans flanges that bolt in with a single bolt. The 02A all have a C-clip for attachment.
I'm also using 100mm Scirocco 16V axles and 100mm 16V spindles/wheel bearing housings. Sence it is still MK1 chassis.

So by going to these later rocco/cabby spindle/axle assemblies will I have to alter or upgrade the front brakes? I mean yeah cool, I wanna do that at some time.. but not right now... ya'heard'me? lol

Guess i gotta get in to a big u-pull-a-part down in Toronto and see what they got. what years classify as the later years? 85+? Also in these years are there any with 90mm to look out for? if they have the calipers/carriers with them should I grab them too?

I was contemplating just bolting it up to the 020 for now.. I don't launch hard ever and I'm super easy on clutches.. No ricer starts.. just smooth low rpm engagement. only get on the power when im well in to gear. I have faith in the 020... I think this will be my route of attack thus far. keep the 02A for a rainy day.. and buy a clutch for the 020.. maybe a %80 kit too?

Lets switch topics to getting the best out of an 020. not for OMFG POWER! just reliability under normal conditions. the tranny will hold the torque, its the clutch dropping it won't take, so it should do fine yes? what are your thoughts?

Upon other readings of people putting modded ABA's and the likes behind older 020's and really making those trannies beg for mercy.. I see no reason why a properly driven TDI (no harh starts, no clutch drops, no intense intens shifts)..

Some would say they have less torque behind them.. I think a modded aba is easily above 150ft.lbs.. even at less torque with crazy starts all the time.. i think would be easier on it to have a smooth driver behind it. Plus all these won't take the torque stories are from people who have put high torque/ high hp motors behind an old 020 and beat it till it bled..

I havent seen any sort of evidence where an 020 has not held up behind normal use... only jack-head-starts.

;) 020 I HAVE FAITH!

like i said on the whoretex post.. it will work, but plan to go thru the 020 if you want life.. :P

my odd ball 2.0 works the 020 pretty good.. eough to loosen the 5th gear retaining bolt into the main shaft without trying.. :D

yea it has torque.. unsafe in the rain with 14x6 wheels.. rips them free at will.. in snow deadly (only 1 time as cought commin home in 1/4" of snow, could not go or stop).. i added 15x7 back in 98 and that helped some.. but will still rip them free if you try to.. better then 14x6 opps style..

i expect my tdi-m to make more torque though :) and like i said.. i think i am at its logical 020 limit.. stock tdi should be fine.. add more power/torque things will get hairy..

make sure to add a lower stress bar.. even one made from angle iron is better then none.. you will get torque steer... thats hard on the frame horns..

UPDATE

nothing of any real importance :P but a post none-the-less.

I ordered and received a bunch of new goodies for my Jetta:

  • New 1" drop/sport progressive springs courtesy of Race Land (excellent customer service BTW)
  • New struts/shocks all around (Monroe Sensa-Tracs.. might sell them and get something different.. but hey $35 a strut and lifetime warranty? I'm game lol)
  • New strut mounts all around (Monroe)
  • New control arms and bushings (Lemforder??)
  • New ball joints (Febi/Bilstein)
  • New tie-rods, inner and outer (Febi/Bilstein)
  • New rotors (Brembo) and pads (NasCAR lol)
  • Lightly used drums and bearings (local autoparts discount special)
  • New Shoes, hardware and cylinders (discount special)
  • H3 fog lights
  • Driving lights

On the "To-Do List":

  • Obtain a VR6 water pump pulley.. anyone got one kicking around?
  • Purchase 100mm axles with lifetime warranty
  • Grind spindles to accept 100mm outer cv's & press in new bearings

Still pending thought process:


Upon talking it over, going with the 020 transmission would be completely stupid, counterproductive, heinous, and just plain dumb... lol.

Swap will consist of:

  • Full electronic TDI, ECU & Cluster
  • CTN 02A Trans
  • Hydraulic clutch
  • Cable Shifter (mounted inside the cabin)
  • Straight exhaust turbo back

so far just stock piling for spring! When the real work will commence! muahaha

QUICK QUESTION!

I need to take the timing belt off (I think i do anyways) so that I can fit the mk1 passenger side mount to the block..

I need to cut away some pieces of this little thin tin sheet behind the t-belt so that I can get this mount in there..

Question being, if I do have to remove the belt.. What must I do to maintain a flawless re-install of the timing belt.. It should be as easy as slip off slip on shouldnt it? I have never dabbled in the TDI t-belt area.

Your help is greatly appreciated :)

It's pretty much exactly the same as an IDI timing belt... positioning is mission-critical and to the thousandth of an inch.  ;D   The proceedure is exactly the same... lock everything down to TDC, tension the replacement belt with the cam sprocket loose etc... the only difference being that you check and dial in the final timing with software rather than a dial indicator.

In this case you can "mark and pray", as the TDI folks call it,  and likely not cause valve interference... but you're gonna need the right tools to lock everything down some day... and seeing as how this is an AHU engine both the IDI pump lock and cam lock should work for ya anyways iirc.
