Hey i just bought a mk3, what first mods do you recommend?

[@Eurolanta6]

I had a 97 MK3 GTI VR6 twin turbo. That was the funnest/ most reliable non turbo to turbo build I ever driven that car was neck to neck in reliability with my wife’s 07 Honda Accord 2.4l in stock form. We both drove our cars for 5 years, and both only had to do regular oil changes, tuneup, and tire changes. And mind you that was my first car I actually set out to build. it cost me my high school savings working at ihop. Ended up with like 5k into the turbo build. And another 2k in suspension. And what made it all super nice was the tune. The tune and who you pick to tune your car will always be the factor that determines if your car will be reliable and fun. Or a money pit then a blown engine… DO iT Right. Nd always use oem Bosch parts where you can. NGK plugs, amsoil oil, and Mann or wix filters..

[@donduck6195]

I have the ko4 on a VW EOS. It's crazy how low it starts to make boost. I can feel it by 2800 and by 3500 it's roasting tires.

[@nateglo5980]

I just recently got a eos what else do u recommend doing to it

[@castin5244]

Needs a remap. VWs don't take well to power modifications without remapping. Everything is controlled by the ECU. Wastegate, diverter valve, etc.

[@r1l3y91ef]

Yup. Well aware.

[@brandonowings4268]

So is literally every car since OBD2 became common use. And it's known in the audi community that a K04 on stock ecu is a noticeable upgrade. Tuning and slightly less tiny injectors will obviously yield more power but only because of factory boost pressure being a measly 12psi

It does spool a tad later and high end feels better and doesn't fall off as much as k03. I can see what you mean if it was on the factory tune. Anyway.

@Kuma Ma-kun its simple and direct. Just undo the old stuff and swap in the new stuff and make sure that you use new crush washers on the coolant and oil feed lines on the turbo.

[@nissantech8857]

Different waste gate provides more resistance before opening which allows higher boost levels even on stock tune. N75 valve upgrade would come in handy

Most Volkswagen guys will know that a K04 is not just a direct bolt on. Especially if your car was a 150bhp model, in which case the standard form is a K03 setup. For a K04 Upgrade, you need a K04 manifold, you'll need K04 oil lines and a suitable K04 downpipe because of the exhaust housing being in a different place. Then in order to make the power you'll either need a 225 fuel rail with TT or S3 injectors, and a BAM inlet manifold, or just buy bigger aftermarket injectors. You'll also need a lot of little awkward bits. It's not just a straight swap, unfortunately.

Shona a k04-001 is a direct bolt on. Your thinking of the Audi TT 225 turbo

[@shona5512]

@@rabbitgti652 Yes, that's what I'm thinking of because that's generally what a real K04 is. A K04-001 is essentially a K03s.

It was $1500 because the whole front end needed to be rebuilt. Mine isn’t a GTI either, it’s been rebadged with the GTI and rabbit logo the the 20th anniversary (but mines an 01 so it can’t be the 20th). Very confused, but very fun to drive.

Did he need a different manifold or downpipe or is it an exact replacement?

It was exactly the same as the k03 but bigger. Not by much. All I did was go through the catalog and chose the turbo that was a upgrade but would be a direct bolt on.

I have a 1.8t golf gti it has the k04 with apr stage 2 tune with 550cc injectors. It's running rich and I think I need to do smaller injectors calling apr tomorrow for some tips but trying to get any advice I can lol it pulls strong but here and there it sputters like its either getting to much airflow or fuel or not enough of one or the other

What is your boost profile... From the video you said your hitting 24psi at 3000rpm, what psi you getting at red line?

[@andrewwright.]

Also it's a ko4-001 so basically not a ko4. It's the same as the ko3-53 but a tiny bit bigger.

[@stevecvntniko8271]

So not worth it?

[@andrewwright.]

@@stevecvntniko8271 if you looking for an extra little bit of power then yes. If your looking for MORE then no. Ko4-23 is another manifold/downpipe/injectors/fmic setup and intake...cost a bit so people slap of a ko4-001 and call it a day. Ko4-23 is 270/75 max so 250whp ISH. If you going to go ko4-23 then look at a cheap gt25/28 setup second hand. That's where the real kick of power is and not with ko3 or ko4....will be more on/off boost with a Garrett but imo VW made a mistake...1.9tdi got the Garrett gt1749 and the 1.8t should have got the gt2561.

[@r1l3y91ef]

@@andrewwright. that's why I chose this turbo. Direct fit but a better boost profile. The k03 peaked faster but fell off at the higher rpm. I'm a little worried because I'm very close to the 300tq as it sits. That's when you start bending rods according to my tuner. So I didn't really want to push that.

The mk4 is my daily. In this video the diverter wasn't performing as it should. But I'm currently running the rkx diverter. Found on amazon for about 45$ the car is probably around 5.5 seconds to 60. But it's a lot more lively on the roll.
