Discover the 1.8T 20v Differences Between Engine Codes & Decide On Your Project Engine & Upgrades

[@ryanherrington9267]

I got this car cupra r 2003 running a nice 350bhp it's very impressive I'm using the AUQ engine 5 years had this car drove the hell out of it and its never broke down missed a beat and its ridiculously quick 😎

[@agtronic]

Man, first sentence of the video and I feel like a dinosaur. “Quite an early engine from Volkswagen”. I still view the 1.8T as “modern tech”. When that engine came out in America I had just finished building a 2.0L 8V turbo and was happy I made 300+ WHP with SDS EFI. Then this thing came out and all it needed was a turbo and a tune and it made those numbers with ease. Then every 20 year old had one … ahhhh memories …

[@spinnetti]

...and now these are dinosaurs.. Dunno why people wouldn't just drop in a EA888 Gen3 like from a Golf R or S3. 400hp on stock turbo and no internal changes. Seems a lot cheaper and more reliable. I did a "stage 3" on my 1.8t 2002 A4 but that had nothing on my simple stage 2 2015 S3.

[@emotionalintelligence776]

Swap the stock frail Rods for forged on the 06A and you are good for up to 500hp. But as ive encountered personally and with others the sweet spot is around 300hp to 400hp unless you enjoy lots of tire smoke. You could throw in some cams and tuning to change the tq curve to higher then stock but you still wont have traction in the lower gears. Most people dont have the money to spend on a daily with almost 400hp basrely 300hp so understand modding a 1.8t aint like slapping a turbo on a k20 or k24. You could do a comlete honda K swap and turbo and still have money left over for the same money you'd spend on just a good turbo for your dub.

[@Fastest_TT]

Hey I have a 06a could I slap a AEB HEAD on ? I need help please

[@nathansutherland892]

K20s are megger money to modify compared to a 1.8 20v You can't get a cheaper engine to go for big power than a 1.8 20v as its been proven for decades and try making over 1000 hp with ya k20 without modifying absolutely everything and spending 10s of thousands when a lot of the standard components on the 1.8 20vs can take over 1000hp as they are because they were built to be a strong turbocharged engine from the start way back in the late 80s. And power for power a 1.8 20v will always outperform what it puts on paper and be faster as it's been proven again and again

[@LL-se1vj]

Thanks for the video! Aqx is small port head found in 2001 seat ibiza cupra. I have a setup with a gt2871r stock block around 330hp and 450nm. Rest is s3 maf and 3inch full exhaust. Power comes in at 4200rpm till red line 7600rpm flat. No problems if you keep it maintenance up to date. Front wheel is oké from third gear.

[@chrismartin6427]

I had a 2000/w,reg skoda octavia estate 1.8T 20v and it was a AGU

[@RedWalnuts]

I've read several places that variable valve timing on the 1.8T is only used to reduce emissions right after startup, and that it has nothing to do with increasing power output or altering the powerband in anyway once the engine is up to operating temperature. I think you might be applying general knowledge about VVT to this engine, where it actually doesn't apply.

[@torquecars]

As far as I understand it depends on which engine, generally speaking the Audi cam timing works all the time and affects power whereas VW only seems to kick in on warm up. I should also have explained better it is cam timing, not the valve timing you might associate with VTEC or similar setups. I was not aware it was commonly only on warm up with VW engines, I had assumed the different brands worked in similar ways, trust VAG eh!

[@matejunsagris]

have B6 1.8t BFB Quattro , already done some mods ( FMIC, ko04 hybrid , decat , 550cc , ) only left rods and valves , my target 300 HP + daily driving on LPG . i will put IE h beam rods 19mm pins , due to the my needs is only 300+ and i like useable low end rpm car in city driving

[@baccchi4425]

for 300 you won't need rods, but it wont hurt to upgrade them, i also recommend putting on exhaust valves and a manual tensioner

[@zinkernator]

I have a Clio 172 cup fitted with an AUQ, with forge sump, K04 turbo S3 injectors with badger5 TIP, ram air filter, Albrighton fuel pump running around 260-290bhp will get it on rollers soon. It’s very quick as Clio only weighs around 960kgs with full cage so is my fun and trackday car. Runs 3inch system into a ktec racing back box so isn’t to loud for Trackdays. Also has a quaife and newly built box as is fwd. I love it

[@maikelnait4495]

I have a 172 with original 169 hp engine that seems quick enough. My biggest beef with it is that it’s fwd.

[@danquinn]

A real minefiedl then.. I've got a BEX in my Audi A4 1.8T 190 FWD. Comes with the K03s. I've never found out if it has forged internals, but it's been mapped to around 225BHP stock. Interesting video, thanks!

[@f.a3202]

From what i know only BAM and another one which i don't remember have forged internals. The BEX does not have them. Basically engines used in s3 and TT have them. Some Cupra's might have them too

[@PeteRock1]

Do you have videos specific to the ea113 2.0 TFSI Audi TTS 8J CDMA engines and their differences? I have a USA 2015 TTS w/ CDMA engine and would like to know its areas of concern and making it reliable and also areas to improve.

[@Sverigebilden]

I like your video and how you explain it. If you will pick one or maybe two engines for a swap into Golf MK2 or MK3 which should i go for and in what car will i find that engine? The only tune will be stay stage 1 chip. Thanks in advance

[@torquecars]

For the Mk2 or Mk3 i would go with a 1.8T AGU or big port/forged from an Audi S3 or TT, they give so much potential with the larger turbo and big port head.

[@Sverigebilden]

@@torquecars What year model can you find the 1.8T AGU or if picking ig port/forged from an Audi S3 or TT year model for the Audi? Any engine from Seat Cupra and year model?

Im owning 1.8t bfb 230bhp/340nm of tq. Nice enough for fwd b7.

[@Bigwicked-wz6ud]

Thank you for this very educational video give me a lot of knowledge that I had no clue about. It shall help me perform better in my mechanics of working on these types of vehicles with this particular engine. I just want to say thank you for your knowledge and information which has much improved mind so thank you I'm looking to other videos you have for knowledge

[@RoccoTakka]

Hi there just wanted to know if there is an difference between the Audi B5 1.8 turbo 20 v and the B6 20v crank sensor ring cos I have spark and fuel at all injectors ni start please help

[@kpariyes]

I just swaped 1.8T AEB 5MT to my 1.8 FWD B5. What's is recommend for upgrade to around 220 HP? I prefer more torque as I do not drive that fast, usually less than 170 km/h. Just want some power for over taking Should I remap, change air filter & intercooler? Or should I change to K03s turbo?

[@keatoncreates]

oh man ive been trying to find out if my car has a k03s it is a 2000 a4 b5 1.8tqs (AJL 180hp) id read the tag but its so hard to get to hahaha, just trying to figure out if a k04 is worth the spend before i stage 1 it (there are some maps for stage 1 k04 or with dump and intercooler only). Can anyone confirm!? None the less, Much appreciate the knowle3dge ive found a lot of incorrect info since i got the car a year ago, guessing because there are so many slight variants of a very old long used block, but your site has been very helpful, and this channel too obvs :P Thanks my man! appreciate your efforts

[@titaniclp1851]

I can confirm that the AJL engine in the a4 b5 has the k03s.

[@Nando84709]

Love the channel mate keep it up 👍 I’ve the Audi tt 1.8t 180bhp ARY engine. Are the any good and what horsepower is the limit?

[@Nando84709]

It’s the Quattro one

[@torquecars]

Glad it was helpful! Thanks for the support and encouragement my friend. Yes they are very good blocks, with the Quattro you can really get some decent power out of those and actually use it. Turbo upgrade and remap are the big power adders on those.

[@juliekirk8358]

Very interesting channel I am looking at the moment to do an engine swap, I’m starting to do my research on the 1.8T 20V I am mk8 transit custom I can’t make my mind up what tip it this engine or go for the VR6 any suggestions please?

[@Fastest_TT]

could I slap a AEB cylinder head on a 06A block? I need help please 😢

[@laszloszell8753]

What we know about the AWT 1.8t VVT block? Internals etcetera? Is a 150hp small port engine. If need i change the roods and pistons, but what about the crankshafts? Is cast or forged? How much can hold?

[@mauiwkeyz7804]

I have a BEX motor in my 2004 a4. Im wanting to by a emu black standalone unit but they dont have a bex harness im just wondering if a BAM adapter would work with it

[@ScalperNora]

Congratulations on the channel. I have a question, are the AUQ and AWP blocks completely interchangeable or not? Thank you

[@Mechanix91]

every 1.8t block is interchangeable with the exception of keeping the timing belt system to match the block, transverse blocks can be swapped into longitudinal cars such as a jetta or gti to a a4, but the topend accessorries and turbo need to be kept from original car to mount properly and the transverse i believe has a output shaft bearing or a bearing of somesort cant remember exactly.

Can you recommend any web sites I can get tuning parts from?😊

[@torquecars]

Where are you based? You can't go too far wrong looking through ebay, even the larger performance brands sell on there now. Demon Tweaks, Awesome Gti are names that crop up quite often here in the uk.

[@Landaultd]

My 1998 Audi A6 C5 1.8 20v with 125HP has an 06A Block too....

[@SirDarkWonka]

Here in Brazil we have cars using this engine with 1400whp. Limits? good joke 😂 However, with original parts it is best to leave it at 300hp, the engine can handle 400hp, but the transmission can only handle a maximum of 350hp.

[@nathansutherland892]

There are original high milage engines making over 600 and 700hp with the original gearbox so don't no where u got from but fully built yes they can handle over 1000hp quite easily

[@4BillC]

I got a real cheap engine for my build that jumped time. It was out of an 04 A4 but didn't have any marking on the head, I have a 99 parts car that didn't have any marking either but the trunk sticker said AEB. How would I know if I have a forged crank or pistons? I'm only going for 400-450hp, mainly I want to see 8000-8500rpm and 28-30psi. What ever hp that makes on a gt28 I'll be happy with, it's going into a FWD B5 A4.

[@Country-r8c]

The code is on the block not the head. You don’t really have to worry about the crank at that power level. The rods are the weak point. You will want forged rods. You should be okay to reuse the stock pistons at that power though.

[@Brad8261]

Did the bfb have large or small port size? Thanks

[@Brad8261]

Also. Conflicting information online, what turbo would be on a 54 plate 1.8t ltd edition 163 bfb? Ko3 or ko3s?

[@rollindeep786]

n2099 I'm fairly certain it comes with a ko3 turbo, mines a 163bhp quattro sport on the later 52 plate which falls under the early 53 bfb models and has the ko3

058 AEB, Only H beam rods, stock pistons, arp head studs, fcp valve springs and ADR cams - 685awhp kzbin.info/www/bejne/qnOnn4avmsqEfdU 06A sucks, because it has M10 head bolts from factory, unlike 058 M11. You can use 2,7bit M11 studs, but you have to drill M11 into block and cut 4 studs threads shorter, which are at the edges, because water jacket wall is close.

What’s the best forged pistons to choose from every day driving on the 1.8 20vt

[@torquecars]

I hate making recommendations as it is very subjective, but from feedback I've had the Mahle, Wossner & JE brands seem to be good street options on the 1.8T. Hopefully our other viewers will chime in with their suggestions for you.

[@JamesSmith-te7sv]

After blowing my aum engine up twice 😢 I now have, a fully forged engine from new oil pump race bearing rods changed to 20m pin new head 7000 miles in now in storage bought mk7 R 😂😂😂😂😂😂😂😂😂

[@renzohey755]

The rods of any 1.8t block can not handle more than +-350hp so 600 will definitely let you end up with a kicked/bend rod

[@nathansutherland892]

Why is there loads of standard 1.8 20vs running over 600hp then and early agu engines running over 700. Hp doesn't affect rods its the torque delivery
