Title: S3 inlet fit a 1.8T mk4 ?
Post by: p4sty on 22 May 2012, 14:35
Hey peeps
I've recently bought a mk4 golf to do up !
Basically taking the engine out and putting a k04 on etc etc ..

Need to know a few things ..

Will an s3 inlet fit if i swap the throttle body ?

Cheers

What engine code you got?

Remember the 1.8t's that had the k04 had smaller inlets, so if you have an AGU it will be different due to the bigger inlets. I'm guessing your after a inlet manifold that faces the other way?

There was one engine that will match the big ports if you have an AGU but the mani is hard to find s/h, that faces the otherway. Otherwise get FMIC and run the pipework over the gearbox into the FMIC and then out the otherside and into the TB, just don't run the pipework to low otherwise it gets in the way of the gear linkage.

It's an agu again as its got low mileage ..

Where do you get them inlets brand new ?
You mean run the pipe off the back of the turbo ( red hose ) to the right hand side , under the tip .. That way ??
Also do you know much about 6 speed conversions ?
I've got leon cupra r gearbox etc etc if that will fit ?

Why do you want to change the inlet may I ask?
Just get xs power manifold and a K04 turbo, custom down pipe with a few other supporting mods.
I wouldnt waste my time fitting a s3 inlet mani imo.
You need the below as far as im aware

-VR6 maf
-injectors
-fmic (2 1/2" pipework)
-3"turbo back exhaust
-225 fuel pump
-decent remap.

Theres alot of money to be spend to feel the benefit of a K04 conversion but good for 300bhp.
Check out Toby's thread on here mate Iv prop missed alot more if im honest.

Goodluck  :cool:

Run over TIP, under would get in the way of the shifter.

If I remember correctly its just a 90degree silicone elbow so just loosen the jubilee and spin it round and pipe from there, you will also need a T-piece that will feed back to the n75, from memory, possibly a 8mm branch from a 51mm pipe, I just grinded the stock steel one down and beaded it, as I'm cheap lol.

You can get brand new inlets from dealers, since its an AGU its big ports, the manifold you need is of a seat 1.8T engine, can't remember the code.

6 Speed has be covered a few times but I believe you need new CV's as well to make it work, a big job with no benefit. I also read gear ratios are identical to 5speed except gear 6, how true this is I do not know. Also single mass fly wheel conversions cost more on a 6 speed gearbox, so when the clutch goes more money. I'd stick with the 5speed if that what it came with.

I've pretty much got everything needed as I break Audi s3's and Leon cupra r's

I just wanted the engine bay to look better with the pipe work etc but looks like I'll have to get some more pipe work :-)

How do I find Toby's thread sorry ??

Cheers

Very nice :-)

By the way your running Saab injectors aren't you ? I was going to use s3 injectors or 440cc injectors can you guide me in the right way ?
I only really know what I'm taking about on k04 ( audi s3's ) kind of similar I guess ..

What I was going to use was -

K04 023 turbo
Relentless manifold
Custom exhaust system Inc Decat
S3 injectors ( will they fit on agu inlet ?? )
Wmi ( depending on costs )
Fmic

That's it upto now but like I said not too clued up on golfs

Any help much appreciated
Cheers

then saab reds will work!

get a badger 5 tip aswell  :cool:

Post by: golf-sib on 22 May 2012, 21:14
The injectors for your AGU are EV6 type fitament which are low impedance (1.2 Ohm) versus the TT/S3 injectors which are EV12 type and high impedance (12 Ohm)

In short I'd look else where for injectors, Calibra yellow's come to mind  :smiley:

Post by: p4sty on 22 May 2012, 21:19
Right ok so s3 don't fit ?
Do you know off hand a list of injectors I could go for ? Looking for 440cc most probably but want to keep cost fairly low :-) .. In regards to the maf can I use an s3 one ?

And yep an AGU motor .. Think I'm going for a b5 tip herd very good reviews !!

Yep use s3 MAF :afro:

Look above two injectors already suggested  :wink:

Injectors are piss of piss on a AGU to do, should be 10min if you know what your doing, with the AUM etc there's so much crap in the way even getting the fuel rail out is a ball ache, let alone the manifold :(

Herd nothing but good reviews regarding r tech !!
I rang them yesterday and they said I'll need to leave the car there for a week !! Can't remember the price but it was a custom map :-)

Also to use a b5 tip do I need a 3" maf ?
Herd I can get the housing on my s3 one made into a 3" one though !!

yeah a week preying theres no problems!  :grin:

mine was £500

390 maping
60 fuel
50 fuel pump

i used a VR6 maf housing and changed the internals
b5 tip is more of less 3" all the way down to the turbo  :cool:

Air mass meter, between tip and air box, registers how much air the engine sucks in!!!

Well you see... Your MUM!

On a serious not, as the turbo get bigger the air that is sucked in increases more and more. Until it reaches a point where the current MAF cannot read the rate of air flow.

Now again, off topic and explain a MAF. All it is, is a heating element where air flows past it, all it does is works out how much the temperature drop is occurring in the current diameter that it sits in and takes into account IAT (intake air temp) & density, does some maths and thats how it works out the air flow. Also when you take the MAF you notice a pug with mesh on it, the mesh is there to smooth (make linear) the airflow to improve reading accuracy.

Back on topic, eventually the MAF reaches its limit due to the way it works as the element can only go so far, so you increase the internal diameter and adjust the ECU to take into account the new area which will effect how it will read the airflow, in short your increasing its maximum airflow range.

Hope this helps

Just seen this. The benefit of fitting an s3 inlet is that if you get all the charge pipes with twin coolers its all a perfect fit and bolt straight on and you don't have to play about with custom pipes and buy a new front mount like me an Toby did but the cooler we got is a beast

Post by: golf-sib on 23 May 2012, 09:12
Don't forget kids he has an AGU so the inlet mani won't match up as it has wider ports, on a AUM it'd work, otherwise its a case of custom mani if he goes for bigger power.

get a badger 5 tip aswell  :cool:

what saab red injectors work as theres a few different part no's on ebay !!

also best place to get a 3" maf ?

and b5 tip the best one to go for ?

anyone know if i need a 4bar fpr / uprated fuel pump ?

I'll find the part no for u,
eBay vr6 maff that looks like urs
B5 is by far he best as it stays pretty much 3" ll the way down to the turbo
U don't need a 4 bar but I used a Walbro in tank pump or a s3/ Cupar r pumps work, eBay for them too or the breaking classifieds

If you could let me know that would be great as there's a few sets on eBay ..
Which Saab injectors are the biggest cc ?
And where do I get a maf from ?
Title: Re: S3 inlet fit a 1.8T mk4 ?
Post by: golf-sib on 25 May 2012, 11:02
Use s3 or LCR maf as its same size as vr6 one and use fuel pump of s3 or LCR.

Not sure on Saab red cc, but its more than adequate for your setup and more, its not like your after 500bhp where 750+cc is needed, plus wayyyyyy too big injectors are a bad thing do don't go crazy and get 700cc stuff.

Oh is an s3 maf 3" aswel ??
Well aparently there's several types of red Saab injectors so trying to find out which ones are which :-)
Would you go for a 4 bar fpr ??
Title: Re: S3 inlet fit a 1.8T mk4 ?
Post by: golf-sib on 25 May 2012, 13:02
S3/TT/LCR all have 3FBR, upping it will increase flow. Just make sure the map takes the 4FBR in consideration otherwise it won't benefit you.

the 3" Maf measurement is the external diameter ;)
