K03/04 - GT Bolt on 1.8T

[Fruit And VAG]

The GTRS is a bolt on version of the GT28RS! It has the same compressor housing just the turbine side that is different!

The three types of eliminators are GT2X GTRS & GT2871R (being the largest)

Yeah I know, but the GT28RS doesnt use the stock manifold, inlet pipe and downpipe as I undesrtand it - so owners of the GT28RS are likely to uprate those components and I wonder how similar a GT28RS and GTRS will be performance-wise as a result. Is the GTRS simply a better design using stock internals, or does the GT28RS have an edge providing you got the mula to jig around with your internals?? I suspect installing a GT28RS with manifolds such as those from ATP in their GT28RS package will give the GT28RS an edge, but only a slim one for quite a bit of increased cost. Hence I think the GTRS is probably the best value-for-money solution out there in BT conversions and represents something that is atainable by more everyday people who are busy and cannot go without their car for a week or two while a garage re-arranges their engine bay.

Your original message you spoke of the GTRS with an aftermarket manifold...

I think with the right set with the GTRS, 350 should easily be achievable, especially with the high flow manifold they are going to be releasing shortly!

This is nice, but my suspicion is that most people who would dream of a BT conversion (like me) havent got time for the install of the GT28RS, and the marketing around the GTRS is with stock internals, not with a manifold change. So in that respect there are possible performance differences on two identical vehicles where one went the GTRS route and the other the GT28RS route. I just think the GTRS route is going to be more bang-per-buck as it were, but marginally beaten into second by the GT28RS in real performance terms.

Maybe I didn't make my point clear the first time?

today got my lcr back with the gt28rs eliminator fitted and revo stage 3
no logs yet but it feels like boost coming on arround 3500 and max boost arround 4000
(and it feels like the boost keeps running till the limiter)

some pictures :

Can't believe they got it in without removing the downpipe!

Seems to fit nicely

What else you got? Did upgrade the injectors or just fit a 4Bar FPR? Does it go well then, i mean is there a big difference in performance?

 

[Feel]

Looks a good job. I'd not read anywhere about a GTRS going on a K04 car.

Looks like it fit okay? Taking the driveshaft out seems a scary thought, but it does create a lot more room. Did you have a look at doing it from above?

What does it drive like off boost? Can't wait for logs.


Edit Snap.

Did you use your k04 exhaust side housing?

GTRS Eliminator exits straight down.

 

[Feel]

They do a K04 fitment GTRS as well m0rk. Just no high flow mnaifold as yet.

Is it me or do the turbine housing studs look a little short?

Edit Snap.

You loosen the manifold/turbo bolts from above but you'd never get it out that way as the engine lies back slightly towards the bulk head! Plus you can only get to two of the downpipe bolts from above, the third you need to be underneath.

Hi guys have read through the 6 pages of info and techno babble and my head now hurts!! lol

Am i right in thinking then from what i have read, i can buy the GTRS Turbo and fit it straight to my leon cupra without messing about with the manifold tip downpipe etc??

Secondly if i did want to go the GT28RS which if i remember is the next one up (correct me if im wrong) i'd have to change a load of stuff in order for this to work??

So just an over view to get more power without going into stupid money how do the 2 compare cost wise and money wise etc??

Sorry if this is covering old ground but i haven't a clue on these things and as said before my head hurts from 6 pages of techno jargon!!

Many thanx for any replies guys in lamens terms!! lol

The best options are the GT2X or the GTRS! GT2X is only slightly bigger than a K04-23 (turbo found on LCRs S3s etc.) which the only thing you probably need is a 4Bar FPR then get a map to suit and you'll be around 270 - 280 with a high flow zorst! A bit more if you increase the size of the inlet.

With the GTRS you'll defo need bigger injectors (LCR/S3 380cc injectors with a 4Bar FPR should be adaquate which uprates them to 437cc which should be good for around 350BHP), bigger Turbo inlet pipe is a good idea which means a bigger MAF housing. People seems to be using the 225 inlet pluming (again found on S3 LCR TT 225) and the ATP high flow exahust manifold would probably be a good idea too, to get the most out of it! Again mapped to suit such as REVO stage 3 which I beliveve are gonna have software for it! With this your probaby realistically looking at around 300 - 310 BHP

The other i would just forget about, if your gonna go real BT then i say do it properly!

Ok thanx your mother so GTRS it is then, with a bigger MAF, injectors, exhaust, ive already got the tip but its for my standard turbo now would that still be adequate or need a bigger one?

What do you meanby the 225 pluming inlet?? soz bit dim i am?

As for the manifold would that be ness for now as i thought i could use the original one?

So this will be ok for my cupra??

Thanx for the time and help mate

 

[HTC]

So does the GTRS compressor need to be clocked to fit the car correctly?

Also are there any plans for you dyno your car.

I'm supposed to be fitting one of these to an S3 soon and I'd like to know some numbers if possible before I commit.

 

[Feel]

Dunno about clocking, I assume as it's a kit it'll fit as it is? Pictures show turbine housing off though, so

ATP website says 350bhp, depending on mapping and fuel. Assuming it IS a GTRS...

225 inlet plumping Air filter/MAF/TIP, the like the S3 and LCR has so it's slighty bigger. So i'd recommend a bigger TIP with the GTRS!.

You'll get away with manifold for now but for an addition £300 quid you may as well do it all at the same time!

Yes this is all for the cupra so you need the K03 fittment kit for the transverse 1.8T FWD, it's all on the ATP website. They do a 3" inlet as an extra but not sure about fitment on that!

 

[The MoffMeister]

ok either way think im going to do that then really appreciate the help mate any idea on rough costage etc??

 

[YerMother]

Probably not going to have much change from 3k if any! But you will have a solid 300+ BHP

 

[The MoffMeister]

jesus, better get another job but for that money cant you go ihi?

 

[YerMother]

It's a common mistake mate!

Unless your gonna do the fitting yourself?

Parts alone (rough costs)

1,100 - turbo kit
400 - injector (probably source some cheaper)
100 - S3 MAF housing
40 - 4 bar FPR
100 - S3 TIP
300 - manifold (if you get if)
500 - remap
Total = £2540

If you get it fitted it going to be around 6 hrs labour (say @ £50/hr). So 50 x 6 = 300

So thats £2840 it's all rough guestimates before anyone starts

Edit: Oh you will want an nice free flowing exhaust too! Another 1k!

Well anyone wanna buy my body? only way i can pay for it haha but then again i suppose most of it can be done by hand if its bolt on etc

But otherwise sod it why not you only live once watch this space and thanx yer mother exhaust a 1k whats it made of gold?? was getting blue flame surely that will be ok??

Nice one cheers all

 

[Feel]

DDX - was your stock k04 flowed? Do you want to sell it, I might know someone who's interested in a new one

How does the Revo stg 3 compare to JD's code?

Just wanted to make sure i got the desired effect!

Blue flame is still around £600 isn't for full turbo back system??
