I hope this is my future. I have a 1.8t aeb manual B5 Passat in my garage. Full bolt ons with stock turbo. The desire to go big turbo has really increased in the last year. Finally caught up in all the maintenance with high-quality parts. Definitely a maintenance heavy car that only likes premium parts.
I have a 1995 mk3 vw golf 2 liters. I need to increase my power but don't know where to start. The car is obd1 hence, I was thinking about changing the wire harness and ecu to a vw mk4 ecu where it can be turned, then I was considering to boost it with a ko4 turbocharger. Am trying my best to work with what have. To make power with what I have. Minimizing cost. What do u think is the best way of achieving this goal?
Is there any reason why I couldn’t use a gfb g-force 3? Do I need to change anything in maestro to switch boost control into open loop? Or does it just force to turbo to do as it’s told?
Any experience with the Link standalone ecu for vw/audi? Building my b6 a4 1.8t, from what i hear its one of the easiest to plug in and tune. Any thoughts?
Haven't used it, but tuning with most standalones is going to be similar. There will be no plug in a and go options, they will all need to be tuned. Much like the plug-in Haltech we used in on of our recent videos on a 1.8t, it still needs to be tuned for the application.
@@COMotorsports I knew itd need tuning no matter what, just wondering if theres a benefit Haltech vs Link. Ill do some research, thank you! Love the channel btw, one of my favorite channels
is there a major difference between golf gti 1.8t's and jetta 1.8t's? I swear i see more jetta's built than golf's. I hate a 1.8t jetta myself but has some issues, and like the golf more
Just curious how come the torque is lower vs the HP on a big turbo. I have a K03 sport on my 1.8T awm engine. And my Torque is quite a bit higher then my HP. Was just curious
Many things play factor in that. However the biggest one in your case is turbo size. The tiny K03 is good a making low end power and torque, but doesn't flow much after 5000 RPM, which is why it feels peppy in the city, but no fun at all on the highway when you try and rev it out further. Put a larger turbo on and it can make similar torque but more peak HP. But with proper turbo selection you can have the best of both worlds up to a certain point. I stopped caring about TQ on a street car at around 400wtq as it becomes useless and just breaks a lot of stuff, so after that it's more so about obtaining peak power. Also note cam selection plays a very large factor in this as well when you start to modify the engine. I've made higher 400wtq, low 400whp then just switched cams and completely changed the graph. Making higher HP and lower TQ... which is exactly what I was trying to accomplish on it.
@@COMotorsports thank you so much for explaining this. Have you or anyone else had any experience with either of these cams. Brian Crower Stage 2+ Cam Camshaft 262 / 272 for Volkswagen VW Audi 1.8T 20V www.ebay.com/itm/362956065824 Or Piper Ultimate Road Cams Camshafts for VAG 1.8T 20V PN: AUD20TBP285 www.ebay.com/itm/323654890675 Or any of the piper ultimate road cams I was really hoping to find a set of Integrated Engineering Street and strip cams but they have been out of stock for years. Really wish you were closer to Pennsylvania. Thanks
Iv got the BORA front end on my 3 Door golf by far the best looking mine is also a 1.8T20v but an early 1 so biggest turbo I can get on it is a K04 absolute riots to drive especially when mine weighs 1104 kg
@@COMotorsports see I thought you was limited due to it being an older system I was looking at a GT28 after your video.but got told it wont work due to it not working on vacuum pressure. I know of a K300 turbo but never seen 1. So Iv just stuck with a K04
8:07 what is the torque measured in nm? And second question has anything been done to the trans ? How would this build go with drags what are the weak points drive train wise ?
I’m mid-mounting an AEB engine from a Passat with the Passat 5 speed. Do you see any difference in performance between the inline vs transverse intake manifolds? I can run either.
I’m going to build a r32 mkiv motor, going to install a bw8374 turbo that was in my other car and I want to know what Parts you recommend for the motor, internals wise.
Stock compression 9.5:1. It's using stock pistons, and the head has not been decked, and using stock head gasket. And I don't follow your question about made same power at lesser boost... what are you comparing too?
CO Motorsports sorry I was under the impression these motors were 10.5.1 or 11.1 compression. If that were the case the motor would have made the power it made with less boost. That’s what I was trying to explain.
@@jdportwerks6795 Ahh... the newer direct port injected engines have higher compression but the older port injected 1.8t engines have lower compression. But yes with higher compression it would make more power with same boost level. The issue then is you can't run as much boost due to detonation so it's a trade off if you don't have good fuel to support the compression.
Actually watched this and the awd vr6 turbo video back to back and was surprised the 1.8t made more power I always thought the vr6 would easily out perform a 1.8t
That wouldn't be apples to apples, although this 1.8t has a similar size turbo 62mm it's much newer technology, and brand new. The other is very old and tired. Next up, we had decent fuel in this one at the end which allowed more timing... which in turn makes more power. If we were able to play with timing on the VR and add better fuel it would have made more power for sure.
I saw in another comment you really like the gtx28 series turbos. What kind of numbers would you see out of a 2867 gen2 on a fully built 1.8t aeb on e85?
You could make similar power to this on a gen2 gtx2867. You'd just have to lean on it harder. The turbo selection did this one was chosen based on the guys goals and future plans. I've made near 700whp on this same turbo on a 1.8t.
CO Motorsports yeah I already have it I just haven’t got it tuned yet, I was wondering what my numbers would be haha It’s in a b5 a4 so I’m going to lose some whp with Quattro
@@hawaiianpunch20v Comes down to boost, engine specs and fuel... oh and how big your balls are. :) The turbo itself is capable of making decent power. That little turbo with quattro is going to be fun on the street.
@@wolfmooo6501 I didn't want to assume incase it was a swap. But I don't really understand your question, what "turbo pipe" are you referring too? This is a complete CTS turbo kit. So all pipes (intake, charge, and downpipe) are CTS.
@@COMotorsports I'm sort of new to the whole terminology that has to do with the 1.8. Yes, I like the looks of the CTS turbo kit on the right side of the engine bay. The engine in mine currently just has a K&N cone filter, and I'd certainly like to consider getting that same kit that's on that one!
@@tylerjdubbs3141 I hear what you're saying... but unfortunately this is the way Maestro is, and plenty of cars have made much more power than this. In fact on this platform, most tuning providers maxed out the stock map on their larger injector files as common practice. Doesn't mean there isn't a better way to do it, but if it works it works.
CO Motorsports it has nothing to do with maestro, this is the way ME7 is... the car has plenty of room for a MAF so why not run one instead of relying on knock based corrections for timing and lambda control for fueling, that’s just such a hack job
@@tylerjdubbs3141 I'm aware it's not a Maestro issue, hence my previous reply. The client wanted a BOV... hence why it has no MAF. Anyways, I'll keep hacking cars. Thanks for your input.
That is alot of boost 29 psi for our shitty canadian 91 gas. Great numbers. I like watching because your a crazy canuck like me. Im stuck with the shity 91 in the GTA as well.
Planning on doing a rebuild like this. Got some questions for you guys: My car 1.8t has 240,000 miles and change my oil every 5k miles and hasn't seen overheating issues in the 17 years that I have owned this little guy . Doesn't smoke or anything like that. Just want to put rods and do a bigger turbo. Something reliable and fun to drive. Do you recommend changing the main bearings or just leave them in there and do the rod bearings? Also did you install calico or standard coated rod bearings? Planning on using the same pistons. Whats piston rings do you recommend? Is Grant fine? Thanks again and keep on rocking this 1.8t builds!!
If the compression is good then you don't really need to change the rings, however since it has high mileage and you're going to have it apart than it only makes sense to do them. I use ACL Race bearings.. in regards to the mains, that's up to you... I've done plenty with stock main bearings. Just depends on power level you're chasing and what it will be used for.
@@COMotorsports Thank you so much! Definitely would like to reach close to 400hp or a little more. A fun street daily!! I'll go ahead and change the rings and throw in some H-Beam rods! Great video!
@@winky_ice Appreciate the feedback, don't forget to hone it before installing new rings. If you're using old rings don't hone and put in same holes, if you're using new rings you must hone it first.
@@COMotorsports For sure its getting honed. Thinking about getting those supertech exhaust valves and changing the valve seals and not decking the surface. Maybe clean the valve seats. What you think? should I send it out to a machine shop?
@@winky_ice If you're trying to make big boost and are unsure of the state of the head then for sure. But if it's straight then chuck it back on. Exhaust valves are a good idea though.
Excellent video, as a tuner what are your thoughts about adding nitrous to setups like this one? my turbo already max out so I was thinking on adding a 50 wet shot on e85
I guess it comes down to what you're doing with the vehicle, what size turbo, when you're looking to spray it.. before or after turbo is spooled etc. Nitrous is an effective power adder, but for the cost.. I bet you could find a newer tech turbo to do exactly what you're looking to achieve with zero sacrafice.
Hey bud that’s a 3 port solenoid I see you up there? I’ve been trying to find out how to do this because I have a mk4 big turbo set up gt3071 turbo border 60 over 60 over je piston cp rod the list goes on man . Just can hook up . Anyways where are you located? I’m in New Jersey and wanted to get the car retuned
These were always great little motors as long as you didn't get one of the ones with the incorrect (or incorrectly installed) rings from the factory that used oil like crazy. I'm guessing those have all either been retired or rebuilt at this point. I'd love to do a little project with one of these, something like a Triumph Spitfire. Nothing crazy, just a decent turbo and injector upgrade. Get up above 300hp at the wheels.
@@COMotorsports yeah, I was collecting parts to swap one in my old mk3 GTI, but life happened. Back then, the hot ticket was a K04 turbo, bigger injectors and a tune. They aren't even breathing hard at 300whp.
@@COMotorsports probably, but back then, that was what you used because the K03 they came with would pop if you turned them up too much. The death shriek of a K03 is a sound you never forget.
Sorry but these numbers are weak, not sure what's missing in the set up but 6262 @29psi should be making well over 400.Most likely in the tuning as I was able to make 360awhp on a gtx2860rs @22psi on a mustang dyno at that. Also If your gonna pull the motor on a customer's build at least wash the engine bay.
Weak but it made more power than you? ;) In all serious stock valve springs are holding it back so I couldn't rev it any further. This turbo needs RPM. I've made ~700whp with the same turbo on a 1.8t with a built head. The turbo is not even getting to it's effecieniny range yet. I assure you there's nothing weak about the potential in this setup.
Nice great work just bought a 1.8 turbo unfortunately it's automatic thinking of throwing in a k04 cuz the stock turbo is pretty much done for not trying to race it really just trying to get a little more horsepower and better response out of it it's a daily driver would love to do a big turbo but as a daily driver not sure if that's the way to go
All depending on the mods you have, power you're trying to achieve, future goals and where you're located. We're located in Canada so parts are a bit more expensive here due to our crappy dollar.
@@MisterMuffin_ Our big turbo program is built around what the vehicle is going to be used for... and the end goals. So it's sort of changes from build to build.
There's lots more to clutch selection then just Torque.. like what are you doing with the vehicle. Drag racing, road course, daily? In short you can't have something that does it all. No problem having two different clutches that will hold the same amount of torque, however one can be suited for more daily use and less abuse, where another won't last as long on the street but will take more abuse. Just comes down to what you're doing with it. But we've seen 400wtq, and track abused for many years on FX400's.
CO Motorsports ok cool thanks for the reply, I’m building a 1.8t and looking into an fx400 for the engine that will soon be in my daily, my goal is 350-400 hp
Great job man! Can I ship my 01 bug to y’all?😂 it’s my daughters car and runs like crap on takeoff but moves pretty well when the turbo spools up. I keep getting 2 codes fuel pump circuit and camshaft sensor a. Any feedback is appreciated thanks
6 or 7r? They both have totally different limitations. If you're talking about stock turbo on either, the turbo will run out of steam before the engines capabilities.
This is my typical go to setup on MK4's. in behind the bumper behind on headlight. -10 line running from valve cover and crank case over to it. Slick, and out of sight.
Where are you guys located I have a refresh block with IE rods and calico bearings pretty part for part setup only difference is I’m working gt3076.63 and atp mani. Are the exhaust valves necessary I’ve seen yes and necessary alot of mixed answer out there I have meth to try and keep temps down regardless.
@@COMotorsports ok thanks for the prompt response so even with meth helping I should still refresh head ditch the sodium filled valves and then I’m good to send it? It’s a street car too idk if that matters. And 350 crank or wheel?
@@COMotorsports wow ok cool thanks a lot you guys are located in Canada? I’m in New Jersey so sadly it’s a trek unless you guys have a sister shop or something but if not do you guys do remote tuning I have maestro 7 but I’d have to locate a dyno rental somewhere
Price really comes down to what mods you're starting with, quality of parts and location. Here in Canada our dollar isn't as strong as the USD so it costs us about 30% more for parts then say someone in the US.
I would not spec this turbo out for a 400whp tops HP build, definitely not. I chat with each client to ensure we're building the setup to their needs, be it autoX, drag racing, street or road course. In this case the customer wanted power and intends to go further with the build...meaning this was just step one. Since the next step wasn't going to be too far off in time I sized the turbo for the end goals in this case, which was more power.
@@COMotorsports Thats great, i have mine fully built except for cams with a MasterPower r494 and i intend to use this Precision 5557 but i dont know if i want full boost at 6k with stock cams, im thinking about it haha, i want more than 390hp though, somewhere around 450 would be fine, you think that with the 5557 i will get there? with water/meth injection?
@@GeroCastreje I've used the 5557 on a few street cars, they're decent. My favorite probably is a GTX28, or 3071. But... you have to remember the quicker the spool the more of a tire fryer it's going to be, if it's FWD.
@@COMotorsports thats true used small turbos before and i dont like the feeling, im not looking for the best build or the more expensive one, just a fun one for the street, that 5557 came cheap (980usd in Argentina) avoided the customs taxes etc. Maybe i just give it a try
you should think about opening up a vw shop in south wales uk, gwent vw so called specialist's in south wales are rip off's, they say they fix your car but leave bolts lose in the engine so it brakes and then they wont to charge you 1000s more on top of say £5000 you've all ready paid them. im gutted as a friend own's welsh coast customs he stopped doing tunning and moding like he used to because of ill health.
I think it’s a crappy setup ! It’s missing at least 1k RPM up top to have useable power ! It finally wakes up at 5k and hits cutoff at 6.5k…if it revved to 7.5k it would make more sense but as is you’re much better with a smaller turbo that kicks in earlier in the RPM range ! Perfectly tuned with a K04 it would be much quicker on the street !
K04 are dumb on 1.8ts. However this setup was built to make 600+ originally. This was just step one hence the lazzy setup, however it got abandoned and this car doesn't exist anymore.
I wanted to know if you would be interested and some sponsorship I have an empty for Volkswagen Jetta 460 over it's got a guarantee 30 Turbo je rods IE Pistons stage 3 tune everything is there there's a couple other things that need to be addressed so we can really lay the power down like it should.

A simple google injector calculator will show you the injectors are over 80% duty cycle on pump gas. Put the rev litter lower so it don’t hit injector duty limit. Do a data log and you will see it go over 100% duty cycle. It’s not boost cut your hearing you have to small of injectors ask me how I know
