Your Dream Big Turbo 1.8T MK4 Pt. 1 

Any chance you guys could rebuild my 1.8t

@@tylerst-onge5257 of course.

I have a killer Audi TT mk1 project I want yall to finish that might top this built.

Don’t let it sit too long

I have a twin divided 6266 and ie race cams I seen it light up right at 5200 rpm 😂

@@btwlbchris3360 lol I bet things start happening reallll fast at that point! Honestly if it goes out to 8800 that’s still a decent powerband. Mines built for the mountain roads, so it’s a different flavor. I bet that 62mm is a blast

They basically don't exist much around here, which is why most have switched.

I've never used maxxecu so not sure how I would have helped there lol.

ECUMASTER SORRY! the build has taken so long i forget what parts i even ordered

For the most part this isn't a DIY channel so you're likely not going to find any step by steps (aside from our AWD conversion car). However I have no doubt you will still learn lots.

Yes. Custom tubular manifold.

Very nice.

I would've went turbo, ditched the g60 awhile ago.

It'll happen.

Loads of builds on FB

More vr6 stuff coming. We are a shop remember so we share some of what comes in the door.

Yes, big power mk6 r please!

This is built for one purpose, street r@cing. So you are correct not ideal for 98% 1.8t builds.

@@COMotorsportsand it'll be an absolute fucking monster of a weapon for that purpose!! Love it, love you guys.

It's part of a complete intercooler kit.

Same engine so when it comes to making power it's mostly the same. Limitation on the B5's is tuning at this level, possible but not without headaches.

I think they have used it, but isn't their preference from what I could grasp

The reason we use emu black is because it's newer tech, global.support that you can pick the phone up and call 24hrs around the clock, the ecu can be used on pretty much engine size or platform, options that are available over ignition, product growth and options, and a handful of other things. I'm sure ignitron is good but for a bit more you get a lot more and can put the ecu on anything.

@@COMotorsports @05glisedan YAY!! This is where I get to chime in on, tell me what it can do that ignitron can't right out of the box? Let's talk straight and only 1.8t, not whether or not it will drop into another car. What the emu black can do before you buy extra sensors or replace sensors in order to use it vs straight dropping it in, for the 1.8t specific build guys. Seriously though, as you know I do tune all formats, makes and models and you obviously know my love of the 1.8t(I would hope after the last 116 years). For a long time 1.8t owner who wants a drop in solution vs other standalones, in this case, the emu black. For anyone else reading, i fukn love ecu master stuff and haltec, etc. So this isn't hating, only point making. For instance, Ignitron is growing, hardware and software wise. It requires no jumper harness, no replacement of sensors, etc. UNLESS, you want too add features(like flex, which is very simple) Out of the box I can do boost by gear, boost by speed, and a variety of traction control strategies and making them all switchable if so desired. Along with multiple boost maps(and switching) right out of the box for my ignitron customers. This is for a model that CAME with the 1.8t I am talking about, not a mk1/2 swapped car. Can even make a race mode to allow a total map switch(in a way) and such. If we just add a content sensor, we can expand that to full E85 and straight 93(which from the pump in the USA can vary from 3% to 12% currently) or activate blending, and have a car that can run everything in between. Which can also be calibrated as desired, etc. Also adding fuel temp just by adding the content sensor. It can do rolling launch, various forms of launch control and such out of the box in a 1.8t platform vehicle. Now, I do have more Ignitron experience than most in the Americas it seems lately, and that is because I started using it in my mk1 20vBT back in early 2019, so I have seen the ECU and company grow slowly and with purpose. I will say, mechanical health still matters, and like any other standalone, this isn't some guy who bougth a file package and just reflashes, so it isn't for someone looking to flash and forget. As many have seen with the content here, Dave and Co put a lot more work than the avg bear into all of this and Daves experience goes back to the beginning of the mk4 platform easily(cos he is fukn old). SO his opinion matters very much to me as a long time mk1 vortex homie. But I will disagree that, for most 1.8t owners looking to take the next step, Ignitron is viable option if they are willing to listen, learn and take on more than they have with their project when it comes to knowledge and hands on work, especially tuning, but is much much easier than diving into an EMU/haltec/ecu master standalone setup. And any competent tuner can handle Ignitron. In no way am I saying the emu black is a lesser control unit, that is not the case, but...for the 1.8t 20v specifically, as a drop in solution...nothing is like it.

I know nothing about tue ady engine code. If it's an internal waterpump block then I'd say it will fit.

This will be a flex fuel tune. So it can ru. Whatever e0 to e85.

Not sure about off the shelf. Likely built to order but the entire intercooler and crash bar is a kit.

Short answer yes, email us with your setup.

Grind it

whenever I think about it. All you do is twist the belt so it's an easy check.

Good tires and suspension (which it has), and boost per gear or boost per mph will help a lot.

I'm not a fan of k04s ok 1.8ts so I'm not the best person to talk to about it.

@@COMotorsports well what would you think an elevation of 735 ft above Sealevel . Atw 550cc injectors XSpower 015XLB (45.4mm/62.3mm) on 25psi , front mount and fbo ? Any guesses ?

@@marksimrow1157n That's not much elevation, I'm in central texas and I am at higher elevation than you. 1326ft. elevation begins to be a factor mostly around 3000ft-ish.

stock are fine for that power level for sure.

CAT 3660 on the small side, 3651 on the large side, unless you want to drastically push your powerband to the right. You will be restricted more by the 3 bar map sensor and intercooling than the oem cams.

On most vehicles it can really help with spool, however on these it's a bit more primitive setup. I've never done a back to back comparison to see plus vs minuses on these engines to be honest. However we do delete it a lot on larger power setups.

They say if it's on from 2k rpm to 5k rpm you see a torque increase then after 5k you see a torque decline from having it on after that. I've tuned brz and 350z and can confirm on a dyno I have seen the factory maps have vvt turned on in the mid range and off at high rpm on these cars. Both brz and 350z gain torque by adding 5-10 degree cam advance in the mid range but benefit nothing from adding cam advance at high rpm I've tried it all back to back on a dyno was curious if you've tried it before with 1.8t on the dyno I have a friend has a link ECU 1.8t and link ECU has vvt off. There's ways to program an output on the ECU to turn on the vvt but I called link ECU directly and they said they leave it off because there's no benefit I've never heard a standalone ECU company say this before not sure if they were just lazy with their development/testing​@@COMotorsports

Girdle is not necessary at this power.

there are guys making 600whp on stock intake manifold and throttle body.

@maxmyslewski we've done it. Doesn't mean it's right and not a huge restriction. However in regards to the hemi throttle body, it isn't required for most big turbo 1.8t builds as it's a bit large, but it will be fine in this.

@@COMotorsports he asked when it was necessary, so i answered. i appreciate your response

@maxmyslewski as did I. For 600whp stock throttle body it's not ideal, It's restrictive and you're leaving power on the table. Restrictions cause increased pressure and heat. It's been well documented that at 400whp you're definitely causing a choke point with stock tb.

Stock

AEB flows a bit more, which means it makes power a bit easier. Sort of like upgraded Cams vs stock.

@@COMotorsports For 500 wheel horse power, for mainly street use, with a G25-660, do you think it's really needed to not fall off up top? I'm mainly concerned with the lower torque penalty.

@ralmslb easy answer, what size charge piping are you using?

@@COMotorsports I'm not sure yet, but I think it will be 2.5" to match the 8P intercooler (I will try to fit it on a 8L S3)

@@ralmslbyou're fine with a smallport, most people are and an AEB should be a least needed item. Factors being - A) they are fukn old and most were not taken care of. B) They were terribly cast in production and the metallurgy is not as refined as a smallport C) with your setup, the usage you will mostly be doing, a large port will hurt more than help, do a set of CAT 3660 cams and see more results across all fuel types and the entire powerband, you more up top, go to a 660.

Mk7 GTI and R is the same stuff. Lots of that content here.

06a block with aeb head bro

Why FSI crank when not needed?

@@COMotorsports not worth the 13% increase in displacement? (with an 83 bore)

@@gunnar6726 I guess my point is, this will already make the power he's shooting for with the parts he has. So would you swap out a crank and pay for a bunch of machining work, and parts to achieve the same goal?

Not In a very long time.

Roger that.

It's all about the tensioner.

most people don';t NEED that belt, as they are driving their cars on the street.

Items are described in video.

☝️That guy. Lol
