    Its Official... I Inserted MY 73MM BIG BLACK WANGER

    I did it guys.. Had to pull my bumper off to take off both lights / change headlight bulbs .... so thought it would be the right time to finally squeeze my 73MM Black WANGER IC into my VAG.

    It was an epic day full of swearing, fiddling around, trimming plastic and dirty hands.. but it was really exciting


    For anyone who is interested or sceptical.. it was actually alot easier than the online ebay ic DIY guides make it out (was alot like the wagner instruction it was sent with)... and the IC was really not that poorly made at all in terms of having to file anything on the unit or make any adjustments or poorly specced out brackets or anything...... really none.. pretty decently made unit that fit pretty nicely


    As per the instruction guide... I was required to trim most of the bottom part off the bottom clips on the radiator (battery hand saw) to fit the bottom IC metal brackets underneath the radiator clips to enable to make good contact with the radiator.. otherwise the ic was getting blocked up on the clips and not making properly contact...

    obviously with the clips cut off and nothing to click in place... it didnt hold perfectly like a clip but it had the room to enter the right position when tightened back together and had to check regularly that it was able to go flush in that area..... .. took a few times trying to fit it and feeling around what part of the clip was blocking but wasnt too hard and finally trimmed enough for it to have clearance..

    gotta say tho... it was a bit of a bitch to put all back together ( IC. PLASTIC TRAY , CONDENSER) and fit it nicely ... fortunately wasnt too time consuming but it was alot of fiddling and a fair bit of patience... .

    one thing that made that alot easier.... i had to open up the top bracket hooks on the IC with a flat head for the condensor plate to slide in.... was maybe 1mm too narrow and giving me a hard time.. ... it opened fairly nicely and easily with it being quite a thick metal hook.. not flimsy at all.. .. and made enough room for the condenser metal plates to slide in... required some downward tapping / light banging with some plyers and managed to get all the plates in nicely and evenly ... condensor looked like it was sittng fairly even and flush.

    i did trim a slither (2mm up and 5cm across) off the top horiztontal running edge of the plastic tray (between the IC and the condensor) so the condensor fits underneath the tray properly and some other small plastic bits to make it all snug... but nothing too outrageous.. literally 1 - 2mm shaving to fit it underneath where it was getting stuck on the tray.

    then

    Once i bolted everything back up it all sat very nicely and tightly... and DID NOT require any makeshift brackets or metal plates... screws.. or anything... like many online guides say.. just the trimming of the plastic radiator clips and some plastic on the tray and bit of patience and fiddling till it looked right and even... then bolted back up and was looking and sitting very nicely.

    wont be driving it anytime soon so cant give any feedback on performance but pretty happy with the savings on the WANGER.. with the money i saved i picked up an impact wrench and some bits to put it together easier (made alot easier).... saved myself a cool $2000+ in equipment and install so happy with that.

    on closer inspection of the wagner installation i completely winged it... and doesnt say in the install to cut the bottom radiator clips off .. it seemed like they were in the way to me so i did that and it all worked out well.

    . it recommends you cut something else off to fit but didnt find that was a problem.. and to modify some other stuff... guess you gotta do some mods for the big STAGE 3 WANGER

    I have no axe to grind with you but how hard is it to post photos of your project if you wish to help others DIYs?

    thats cool, didnt feel like it needed photos.. theres about 10 - 15 videos online of installing intercoolers (mainly from the front, 1 or 2 from behind / removing the radiator)..... i did mine from the front method.. without removing the radiator or fans.... and to be fair i was actually too busy getting the job done and back together aswell as removing headlights, changing out some bulbs before .. had to put em all back in after and jumpstart my car to test the light bulbs e.t.c was sort of over it by the end if you could forgive me.. hands were basically covered in dirt and grime most of the time to be fiddling with my phone or taking pretty pictures.

    but in saying that I do have a few photos before i really got stuck into it... that i havent uploaded.

    not sure if they will get me a pass or lift my approval rating with inspector general lucas_GTI... but i can upload them if get around to it and you guys let me know ok.


    and I really do appreciate it wasnt as beautiful or cute as lucas_GTI's do888 thread... i wont deny it.... but atleast i do know the specs of my IC and why i bought it and how it functions .. just a little bit


    also, im sure to those guys who were wondering how hard these things actually are to install... they are not as hard as alot of the online threads make it out (custom backing plates, screws, fitment & rubbing issues ? e.t.c e.t.c)..

    apart from all the tools that are needed for disassembly of the front end... i think i only needed my battery hand saw as extra for the plastic radiator clips (mentioned in the instruction).. and after going over the re-assembly i might need 1 small screw to go into the existing condensor plate hole to hold it firmly in place.. otherwise its pretty good as it is but i will do that to be sure it doesnt move at all.


    Personally, I think its a little bit nicer for a DYI'r not to get bombarded with all these random photos (which arent necessary if you've already seen the videos and get started yourself .. which everyone is going to anyway).. it makes it look daunting... i definately know i thought i was in for a much tougher time as a DIYr from the online threads going around.. it was actually alot easier and to be honest most of them sounded like a lot of Garage-Overengineering, bitching a moaning from the guys installing them... needing 2 people to do it e.t.c e.t.c... i did it all myself basically on 1 leg and limited energy / time in the day.

    If i didnt have a sprained back and swollen foot i would have rated it as.. very easy aslong as you have the tools.

    So to recap..

    I followed a few of the front install videos (they all show u the same things) to get it all undone... did all that..... removed my OEM INTERCOOLER (actually had to crack the top clips to release it).... after trying to slide the WANGER in the same way (had no issues getting the top clips in and out of the WANGER, which was very nice as i had to place and remove it to trim the radiator clips)

    .. after trimming enough of the bottom radiator clip/tabs until it had enough clearance to fit in .. and left as much of the tab as i could.. . it didnt really clip/click in properly but this gave the clearance to fit the IC bracket underneath what was left of the tab and fit parallel into its right position in the front cooling sandwich without it being angled or misalligned. .. and then basically put it back together in reverse the best i could and it was done.. needed a little bit trimmed off around the plastic tray thing that goes around the IC and Condesnor.. to fit the condensor back in flush but that might be a situational thing and someone might not end up needing to do that.. i did just to be sure its sitting properly underneath the tray instead of over it... please keep in mind the condensor will be 20mm further away from where it was so thats why i had some trouble fitting it back underneath where it was without the trimming..

    anyone who has undertaken this or will do it , will understand what im talking about.


    As for a link to purchase.. its a 73mm comp cooler on ebay look it up. pretty sure i've covered that already...

    the inlet / outlet is 73mm and the thickness of the core is 55mm just to save anyone confusion.. the stock core is 37mm so its a decent improvement in size but didnt give me the fitment issues like some other people online have been claiming with their ebay ICs.. maybe they got some thicker ebay unit / bar plate or something i am not sure as there are 5 - 6 different ebay units right now.. and probably more specs over the years.

    from what ive seen the do888 is even thicker so that might prove trickier to install than my WANGER r.e the condensor fitting back underneath the plastic frame.

    as always, happy to help anyone with actual questions

    I agree, it would be great to see some pics - even from after the install if not during.

    And dead keen to hear how it goes once you do get driving again. Did you manage to collect any data from before you fitted it so that you can provide before and after data to qualify just how much improvement the mod delivered?

    happy to take some more photos of it with it bolted in before i put the front bumper / plastics back on (sort of looks the same as before i dismantled it LOL).. ... and some photos of the inlet outlet area / sillcone / clamps... i think 73mm inlets are about the max you want to go on the MQB if you want to fit the appropriate 73MM sillicone tubing on without a problem..... if you go bigger than that you probably dont have enough clearance around that area to put such diameter tubing as a section of the radiator will get in the way (might need to cut more on the radiator but stopped paying attention when the tube fit).. .. it literally just cleared the radiator and slipped onto the inlet tank relatively easily (which means some force to get it onto cover the whole inlet)... with the clamp on it has about 1mm clearance to play around and adjust / press it onto the IC tank while tightening.... but really didnt have too much trouble getting it all the way on to the end and tightened up..... a little bit of sillicone grease would have helped it slide easier but i couldnt be bothered getting off the floor at that point.. the outlet tank area was no problem at all for the sillicone installation which was nice.

    Unfortunately the car is off the road / unregistered because i needed to fix the waterpump, headlight bulb, oil pan gasket leak ( yet to do) for rego safety check and had the intercooler install already in mind while the bumper was off.. . dont really need the car so havent bothered... been feeling more energetic recently so thought id do it all this weekend.


    - Unfortunately I didnt log any info, statistics / diagnostics of the OEM cooler temps or performance but im sure there will be plenty of people online with those exact same stats and also results from a WAGNER TUNING cooler specifically .. before and after.. and ebay coolers too (which perform as well as or very close to the big brands - 10 over ambient in most open driving scenarios... heat soak when standing still)

    I am yet to find any user info or reviews on this particular sized 73MM comp cooler .. so i literally am the guinea pig for the world to see on this item.... all i know is it has the same spec / build dimensions as the WT 70mm cooler but the larger inlet /outlet... figuring it was some prototype / test cast from WT now being pumped out from china.. and is nearly similar weight (8.xkg WANGER vs 9.2kg WT *CLAIMED) may be the same after converted into pounds depending on equation used... or maybe i got them mixed up.. either way it was pretty close when i did the scales.

    ill probably get a bluetooth / phone ap for the JB4 to measure cooling temps if it has that feature.... otherwise i might log it off the computer... need to look into whats best.


    personally, im keen to see how the car drives with 73mm inlets and the bigger tank compared to the 60mm oem inlets.. there may be some turbo lag but hopefully not according to a few reports the is38 has enough power / pressure to fill the larger tank without lag and the larger inlet / outlet diameter helps alot with temps and pressure drop / flow.... Giving me optimum flow in the IC for up to approx 7OOish HP at the engine (probably will never reach that) where as the ICs with smaller inlet / outlets max out with optimum flow at around 500hp..

    if u guys notice the black plastic tray around the condensor / IC.. i had to trim the top running edge approx 1mm up and 5 - 6mm across to fit the condensor back underneath it.

    I did leave out 1 install detail... I remember i had a little bit of trouble with the rubber grommet holes on the bottom of the plastic tray where the bottom IC stems fit into.. it was just really hard to get them to fit in there i think the holes on the rubber grommets werent big enough for the stems.

    I pushed out the rubber grommet things and put the IC stems into newly wide open holes with no rubber reinforcmenet.. then i proceeded to jam the rubber grommets back into the hole from underneath the unit making sure its properly tucked in there between 1 side of the stem and plastic tray so it doesnt move around.. its not perfect but it works and saved me cutting the grommets into pieces to stuff in there.

    There's lots of data out there, but none for your particular car. What always interests me is not absolute values (those are often so easily gamed) but rather delta values. And those are never relevant unless they're done on the same car, but the same operator, in conditions as close as possible to each other (with variations noted).

    I am yet to find any user info or reviews on this particular sized 73MM comp cooler .. so i literally am the guinea pig for the world to see on this item.... all i know is it has the same spec / build dimensions as the WT 70mm cooler but the larger inlet /outlet... figuring it was some prototype / test cast from WT now being pumped out from china.. and is nearly similar weight (8.xkg WANGER vs 9.2kg WT *CLAIMED) may be the same after converted into pounds depending on equation used... or maybe i got them mixed up.. either way it was pretty close when i did the scales.

Giving me optimum flow in the IC for up to approx 7OOish HP at the engine (probably will never reach that) where as the ICs with smaller inlet / outlets max out with optimum flow at around 500hp..
    Turbo lag is generally due to the size of the turbo and how much exhaust gas flow it takes to spool it up. I've seen lots of comments about longer intake paths and larger intercooler volumes meaning that boost takes longer to build because there's more volume, but honestly, at the pressures and airflow rates we're talking, the difference is absolutely minimal.

    You should see better performance though, as there should, all other things being equal, be less flow resistance through the core and pipework, and so less pressure drop between the turbo and the intake manifold. More pressure equals more air equals the ability to burn more fuel equals more power.

    As before, thanks for photos. If you include the "rubber flap" (designed to help keep airflow going through the core and the radiator), what's the thickness of the OEM setup? Looks pretty similar to the Wanger - meaning that the Wanger's about as big as you can get before having to compromise fitting. Nice.

    I do wonder just how much airflow that crash bar blocks. I realise it's illegal to run without it (and the bumper covers it anyway), but I just wonder how much better engine cooling (and intercooler performance) you'd get with that out of the way. Looks like you've managed to swallow a small bird anyway, so the flow can't be too bad!
