Best 1.8T 20V Tuning Mods [Seat, Audi, VW, Skoda Tuning Guide] 1.8T Engine Performance Upgrades

The 20V 1.8T referred to as the EA113 predecessor is a great engine, so we'll look at the 1.8T Best Mods & Tuning Upgrades for your VW AUDI SKODA OR SEAT 1.8T Engine project.
Our focus is on the 1.8T turbo since 1993 the (Not the EA113 TFSi version as this 1.8T will be covered in a future video.)
If you know what the common tuning problems are, you can be prepared and hopefully avoid them by fitting the best mods and upgrades so we will highlight our selection of the best mods and upgrades for your 1.8T engine.
This video covers the tuning of the 1.8T engine and how to get 350hp and what pitfalls to look out for when you are adding power to your 1.8T.From turbo upgrades, to remaps and other performance mods like fast road camshafts, induction kits, head work, big valves and swapping your fuelling.
In depth coverage of tweaks and mods to the 1.8T's N75 valve and detailed explanation on what this is and what it does.
Small Port size head Engine Codes: ADR, AMB, AMU, APT, APU, ARG, ATC, ATW, AWM, AWP, BEA, AWT, ARX, ARZ, AWC, BJX ,BAM, APX, AMK, BVR, AJQ, AJL, APP, BBU, APY, AUQ, BEX, AYP, AVJ
Large Port size Head Engine Codes: Typically 97-99: AEB, AGU, AFY, AJH, VVT was included on AUQ, AWU, AWV, AWW, ARX, AUM, AWP, AMK, BAM
Use of Blow Off Valves in the 1.8T
Because of the loss of system pressure caused by the installation of a blow off valve or dump valve, difficulties with engine control may arise so we look at ways round this and your options.
This video also covers mods on the K03 K03s and K04 turbos and how to tune them and swap them around when upgrading your 1.8T engine.
Generally speaking the AGU APH ARX AUM AVC AVJ AWC AWD AWU AWV AWW BFB AJQ APP ARY AUQ BEX AMK APY APX AJH and BAM came with forged cranks but there are some exceptions to this list

Am a old geezer, ended up buying a random ibiza 2006 cupra, 1.8t to do a 2 mile work run, pretty surprised in how good this engine goes, which has led me to this, good listen

[@zeusricochant7357]

Ive got an 03 a4 Avant 1.8t (bex) with under 90,000 miles. Been off the road for a wee while but it's going to be project. Love it so much

[@s.o.s.exploration2412]

I love my 2004 VW Passat GL Wagon. It has the not as favorited AWM 1.8T, 5-Speed Manual. USA variant. It has almost 230k on it, but it doesn't burn a lick of oil between changes. Ever since it came into the family we have kept up with oil changes religiously as well as the appropriate belt and water pump replacements as well as kept an eye on the pcv system and common steering issues that accure with the multi-link suspension design. I'm going to be bringing it out again this year to VolksFest in Milwaukee. It is shaping up to be a great year for the ride after putting the work I've done, restoring it, being in my hands after getting it from my X-wife. Such a reliable motor not causing much of a fuss after the 18 years of its life being in and through the brutal Wisconsin winters.

[@emotionalintelligence776]

If you're interested in a K04 and you already have a K03s keep looking. If you somehow feel the desire for more power then go big turbo. The reality is most people and I can't stress it enough don't need anything more than a tuned K03s with full supported boltons. A fwd car like a vdub with a huge low tq curve just waste energy spinning your tires in the first two gears. There's nothing wrong with a working N75 and unless you're a mechanical engineer the so called performance N75 is the same as the one in your dub. It simply has the screw turned full left inviting spikes and other shenanigans that kill your turbo and or motor, just leave certain things alone. The best information is what applies to how you're going to drive your car decide wisely it's your money, your license and always your life that's at stake.

My old 2001 Audi TT Quattro 225 had 267k miles on it when I sold it. The only thing that went wrong for over 40k miles was coilpacks. I was told it's from high rpm shifts with a unitronic tune. The current car I own, another TTQ225 has 103k miles, all stock. I absolutely love these cars. They just work.

[@torquecars]

Got to agree with you, it was bulletproof. I loved mine and it never missed a beat. I only sold the car because it has some accident damage and was gutted to lose it. It was the last fantastic Audi VW engine IMO before the world went eco friendly and everything is run by computers and gadgets.

what mods should i do to get 220 whp? On an AWP golf gti engine?

[@jungillestt02]

I have a 02 Audi TT 180 Quattro with the AWP engine. Fun car, haven't done much besides a nuspeed intake and silicone hose pcv kit. Turbo inlet with a turbo silicone breather kit and fmic with forged diverter valve and new n75 along with a down pipe are on my list so I can remap it with some decent results. I plan on a tranny rebuild and clutch way before the map though. One thing I can say is the ko3s feels great comes on fast and hard but definitely feels like it's being choked up a lot by the stock inlet and outlet (down pipe) side of things getting to the upper rpm range. Low end torque is great though for daily driving around the city.

Cool video mate, I've watched you before and like what your doing. I got an a4 1.8t bex. Some idiot had put a k04 on without tune or supporting mods and it blew its self up. I am putting it right and have put a k03s bk on, new waterpump, thermostat, proper fully synthetic oil, changed the timing belt plus tensioner. New solid front subframe, brake calipers on the front, discs, pads on the rear. Getting a bit of overboost still, but will be replacing n75 for standard vag part. Really good cars if looked after properly.

[@torquecars]

It depends on what you need, personally I avoid those with a DPF as I do lots of short journeys. The TSi is better suited to me and I like the wide power band but my 2.0TDi pulled like a train and gave great fuel economy. With the same power the TSi will generally win in a race but the TDI running costs are generally lower and more reliable.

Stock everything, just power mods 350bhp is quite easily achievable. Even stock clutch holds to around 300-350 depending on the way you drive and the wear that is already on it. Stock intercooler will do you fine till the 300hp mark as well. Just tuned my friends' 150k mile/250k km B5 1.8T with very minimal mods and it was neck and neck with a 360bhp dynoed B5.

[@daviscrawford8452]

Right now I have a 2004 b6 a4 that’s got a ko4 turbo with apr stage 2 tune and other supporting mods. I just fixed a boost leak so I’m enjoying the car making full boost but I do think the car has more potential.

I have a unmodified 2004 Avant A4 B6 1.8T BEX 6 Speed manual Quattro S-line My question is what mods to I need to have it ready fort a re-Tune for a bit more power ? Also what was done to yours, the supporting mods?

I have an 01 Audi a4 1.8t FWD 5 speed MAF-less with a big front mount intercooler, atmospheric blow off, K04, methanol injection with 550cc (@3bar) injectors fuel pressure is stock 4 bar and upgraded fuel pump. Car currently has about 250hp at the wheels. Going bigger turbo soon, already have the parts just need the time. I personally did the tuning with Eurodyne Maestro. I also have an 04 A4 1.8t didn't do much to that one yet, and a 2014 A4 2.0T running a Intergrated Engineering stage 2 that my wife drives.

[@torquecars]

Nice spec, you are clearly a fellow Audi fan! Any traction issues? Nice to have you along for the ride and thanks for the support. I've got plans to cover these engines in more detail so stay tuned.

[@4BillC]

@@torquecars first gear just spins but second gear hooks.

[@torquecars]

Who needs first gear anyway. Have you thought about a differential upgrade on that? It should help with traction, you'll probably find it's just one wheel spinning up most of the time.

[@4BillC]

@@torquecars I'd love to put a better differential in it! Unfortunately that is way out of my budget. My car didn't come with traction control but it was equipped with the EDL, but since my abs module is shoot it doesn't work. From my understanding it will apply brake pressure to the spinning wheel to force the tire with grip to get more torque. I do have another ABS module, just haven't put it in yet.

Hi, nice video , I have a question, if I install a solid mass clutch instead the floated bi mass clutch could it generate more vibration or any issues? Audi a3 1.8T 8L

[@torquecars]

Glad it was helpful! Thanks for the support and encouragement my friend. You will get more vibration, but these engines are fairly smooth and the transmissions are fairly strong. Ask around and see what feedback you get from the many forums, personally I would go for it but not too light on a road car.

[@sydallen4381]

Great video, but a bit confused about the injectors discussed around 27 minutes. I have an APX engine, K04 turbo, 2000 Audi TT quattro 225bhp/165kw. I'm thinking of a remap. Your video says that the APX usually have the Bosch 315cc injectors, but also says the K04 turbo models typically had 386cc injectors. How do I tell what my engine is fitted with, before I get the larger injectors? Thanks.

[@torquecars]

Yes it is extremely confusing. Different cars from the VAG group in different regions met different specs and some years had other parts thrown in. Understandably the info online is very contradictory and I rewrote this script quite a number of times but this still slipped through :( ! Any injector quoted capacity on these is generally - or + 28ccm at 3 bar. The rail pressure has a bearing on how much an injector delivers so raising the rail pressure will extract more, and a worn engine may report much lower when measured. From what I can find your 225HP APX with a K04 used 06A906031J with an average flow as per the listing in ETKA and ELSA : 358cc so between 330cc and 386cc. Your local dealer should be able to confirm your part number based on region year and model spec.
