@FabiaGonzales yeah but there a little bit expensive:)). i will try to buy a bigger 1.4 turbo maybe a used one and rebuild it. Could you estimate a power on my current build but with a 1.45 bar instead of 1.5 bar? thank you so much.

They are*

I can't really give an accurate figure but id guess you'll probably lose a little peak torque but keep the same max power

@FabiaGonzales oo thats good, i think that torque is a little to much for the clutch and transmission. thank you so much man!

Mine boosts way higher than its supposed to (on external sensor it peaked at 1.7bar just before boost cut kicked in!) and was making around 325nm! My clutch feels as though its quite worn but it still held it no problems!

 

If you have the 5spd box i'd avoid lugging it at low rpms full throttle in 5th gear as that seems to be a weak point of those boxes (it puts too much stress on the bearing at that end of the box). Haven't heard of any such issues with the 6spd box yet.

 

The larger 1.4 tsi turbo doesnt like to hold a steady boost, it wants to peak really high or hold a much lower boost. It's difficult to get somewhat of a midway, and as soon as we took it for road testing it was getting giddy and boosting too hard again (it was making some good turbo spool whistle sounds though hehe)

@FabiaGonzales yeah.. i have the CJZC engine so it has the 5 speed trans.. sometimes its slips and sometimes it pulls very good.. like it slipped from 3rd to 5th like 3-4 times i tried then for like 3 weeks i pushed it very hard almost daily and it didnt slipped once. 

So i dont kno if its the clutch or its to much torque for the trans to handle.. 

@FabiaGonzales sorry, can i find an uprated MAP sensor?

An uprated map sensor must be mapped in properly, if you don't the boost will be much higher than you expect with no extra fueling and you will run far too lean and probably melt the pistons!

 

I don't know of any but JBS is the place to go for that sort of thing because of their work with the hybrid turbos (which incorporate a map sensor upgrade too)

aa ok, thank you so much!!

@FabiaGonzalesany update on your build?

Not as of yet. Lockdown's put a bit of a hold on things as i don't live close by anywhere, but i've been speaking with JBS who've said basically for anything beyond the stock turbo, you have to start looking at uprated MAP sensors.

 

The stock map sensor can read up to 1.5 bar boost and the ecu is configured to cut boost if it gets too close to that, so to get much more than about 1.2bar (stage 1 ~130bhp, with stock turbo) you need an uprated map sensor, which supposedly increases the maximum boost the turbo can see along with the internal limiters that come in just before that maximum.

 

The uprated sensor needs mapping by a tuner though, it's not a simple plug and play, if you do put it in without mapping it, you'll probably destroy the engine as it'll run far too lean.

 

JBS have told me they're working on a hybrid turbo which they expect to produce around 190-200bhp, it's a similar but more optimised design than simply slapping on the 1.4 turbo (i'd imagine with lower lag and more top end but I don't know any finer details than that though).

 

As everything's been put on hold, debts from elsewhere have cleared and i've a bit better cash flow (promotion at work along with more hours woop), so i'm getting the suspension up to scratch while i wait for some news on the turbo front. Depending on how much ive saved up going into the new year i might even go the full hog and go for the hybrid if it comes out decent looking.

With MAP sensors, you have to take into account that boost is additional to atmospheric pressure, so 1.5 bar boost is 2.5 bar absolute. The stock MAP sensor is a 2.5 bar unit, the part you linked wouldn't have any affect, so that leaves a couple of other options;

 

A 3.0 bar MAP sensor.

https://www.darksidedevelopments.co.uk/products/vw-3-bar-map-manifold-pressure-sensor-038-906-051-c.html

 

A 4.0 bar MAP sensor.

https://www.darksidedevelopments.co.uk/products/genuine-vw-4-bar-map-manifold-pressure-sensor-small-probe-03k-906-051.html

 

That's going off if the one you linked is the actual stock unit, i'll take a peek on catcar.info and see what i can find regarding that.

 

Edit;

 

Stock part number is 03G906051E, looking to see what the specs of that is - most places are showing up as it being a 3 bar sensor, but that wouldn't make sense. I might pull the intake filter off and see what's actually in there later..

I think 3 bar will be more than sufficient, it's just finding one that will fit and work with the ECU. At the moment I want to finish my suspension work and brakes as I've already got or ordered those bits and in the new year I want to get the exhaust done. Then I will be looking at this again.

I've also been thinking about an LSD and clutch pack upgrade.  What a money pit!

I've been looking into it a little more, it would seem that the stock map sensor is rated for 3 bar, but i can't find any actual solid information. I've messaged JBS regarding this. It may be that it is a 3 bar sensor, but the internal limiters are set much lower.

 

I'm getting suspension sorted, then having the turbo mapped in, and then looking at exhausts. Maybe looking at a high-flow intake pipe between the turbo and stock air filter box at some point along the line.

Didn’t it already make 200bhp?

Yes, but pushing beyond 1.7bar peak at only a little over 4k rpms (hitting over double the peak torque as stock), i don't wanna kill the engine! At least not yet anyway! Give it a year or two to live at least so i can save up for a built 1.4 hybrid replacement to drop in when it does go haha

 

At a safer boost level (1.4 bar ish), it should be good for 200bhp at higher revs, with a nice wide power band from 3k to 6k ish. It needs more work on the mapping to get it dialed in correctly, and probably a map sensor.

APR offers a 3bar map sensor for the EA888 2.0 tsi (which they say come stock with a 2.5 map sensor)..seems a bit odd for the 1.2tsi to come with a 3 /2.5 bar map sensor when the bigger power makers come with the same.. its not the 1.4tsi that is a bit closer power wise or by turbo size..

Not strange at all as even though it’s a smaller turbo it needs to make more boost to make the power

so a tuned 2.0tsi with a stock map sensor (same one on the 1.2tsi ) can run 320hp  with boost lower than 1.5bar?

No cause the turbo size is different.

 

I make 2.4 bar for 300bhp, my friend makes 2.3 bar on his car but due to him having an 76mm turbo he makes over 1000bhp.

After getting the turbo mapped has anyone noticed low down power improved. Mine has very little low down power under 2k rpm compared to my old 1.4 140 Ibiza. I bought my old fabia back yesterday 😆

Has it been fixed?! Haha, yeah below 2k is still pretty weak. There's a lot of lag but from 1700 ish the boost does eventually come on.

yea its been fixed. it needs a washer bottle as it has a small crack so when filled over half way it slowly dripples out. im guessing bumper will need to come off to access it. the only think that concerns me it that on some roads the steering wheel it to the left when going straight. I hope its needs an alignment as I never got it done after fitting springs.

Hey , recently got this rtmg ea211 1.4tsi hybrid turbo for my fabia , it came without a wastegate actuator so i wanted to ask if i could attach the one from the stock turbo or should i get a new none oem one?

Great to hear yours is making a come back.

I think after mapping there is improvement low down compared to stock but its completely overshadowed by the increase in power once the turbo comes in. Of course it's got some lag as its only a small engine running a turbo for a larger one. There's always a compromise to be had when pushing more power from smaller displacement, you can't have it all unfortunately. A hybrid turbo would help but they are mega expensive and I don't think the lag is that bad
