Thank you! This actually made heeps of herzpewrz! xD
I have the Seat Ibiza 2.0L GTI from 1997 with the ABF engine, and no joke! This I can strongly recomend doing!
Thanks for your comment friend.
Faster acceleration on Lower rpm’s I guess? Did you dyno’d it? Thanks!
@@Kegels_gti_16V it revs upp a lot faster. Like the flywheel lost half of it's weight!
No did not dyno 🙃
Port matching the Mani runners about 5-6 inches,and the stack completly made a noticeable improvement on mine ... Youl be glad you did it...look into the phenolic spacer before yo do 😉
yep the standard port matching on the lower manifold to the top part is really bad, at the point which is the most important. That will be coming in the next ABF video ;-) tested phenolic's and we didn't see any real drop in manifold temps on the 16v due to the manifold design and the main heat sources being the cam cover and exhaust manifold at the rear of the inlet manifold.. Seen a very small drop in temps by making a heat shield for the underside of the manifold at the back.
@@RestoDesignsnando How did you measure the temp difference?
I certainly imagined it would do naff all due to placement,but I'd still like to get it...iv not done the t.b porting yet,but have done solid 90° 76mm Alu pipe from t.b to a 65mm black silicone joiner to airbox ... And run crankcase filter off the breather housing so no secondary pipe to join..
@@clintonquinn3755We drilled and taped two standalone air temp sensors into the manifold, one at the back of the manifold after the T/B in between runners 2 & 3 and the second one on the lower half just under the flange on runner nº4, also used the standard temp sensor some manifolds due to A/C cars to get an idea of surface temps as well. Heat sock at ideal is shocking on ABF's running Digi setups and 16v K-jet cars.
Something to be said for someone to 3D print up a front style inlet manifold out of plastic with slightly shorter runners
@@RestoDesignsnando by no real drop any increase in reduced iat's is better for combustion,notice any shift in the rev range? Liking the sound of the heat shield👍
Mais uma excelente informação Nuno 😀 já andava com a ideia de fazer ao meu jetta mk1-abf agora vou mesmo avançar com este pequeno upgrade
Thank you friend.
Can’t wait for my golf 1 with abf 🙂
Good job 👍
Thanks a lot mate.
@@RestoDesignsnando You're welcome :)
Good how to! I’ll be doing this soon 👍🏻
Will you check the gains of doing this?
@@glennkegels2166 yes once things get a little bit back to normal It'll be going the stealth racing
Resto Designs I hope to see a vid 😎 I’m planning a dyno testday after summer as well 🔥🔥
@@glennkegels2166 cool would be interested to see your results mate
@@RestoDesignsnando still no new dynorun,
But I’m back with doing mk3 16V things 🔥
Nice , and thank you for your time and effort. So , I'm having one seat Ibiza cupra , I found her in not so good state but with good engine, and now I'm rebuilding the gearbox , changing fuel pump , cleaning throttle body etc. Can I do the same like you with manifold , and does it fit in seat chassis ? Also , I want to put full custom exhaust system , so do you have any tips how to improve power, mostly mid-range. Thank you , I'm new in ABF world. Cheers 👍
Thanks for yoursupport, I had a 2 door Seat Cordoba 2.0 16V ABF in 2000. Great cars, Yes you can do the same with a manifold as the Seat 6k front half is Golf mk3 with 4x100. The Manifold helps in the mid range torque, exhaust 63mm works best on ABF, and look at getting a good chip for the ECU. One thing I really like doing on the ABF is the flywheel and replace the gearbox. The std CDA gearbox has a 3.6FD which in real world gets 95mhp/155km in 3nd gear, which is too long and kills off acceleration, try to find a 3.9FD gearbox from a early mk4 non turbo gti which has this gearbox as well as lots of other new and old cars like Corrado's and B3 B4 Passat's, makes a real difference like you've added 50hp. 3nd gear does 80mhp/140km which is normal in most cars with a 2.0 N/A engine.
@@RestoDesignsnando thank you very much for all your tips. I will post on ytb everything when I finish everything. Stay safe , regards from Belgrade.
Sweet video! I wonder if this is worth doing on a 9A 16v on Digi 2.
The 9a Digi 2 is a engine I've not seen here in Europe, it has a two stage throttle right? and if it's like the euro KE-jet 9a they have wedge shapes screwed on only the small throttle, so not going to make a big difference, maybe look at the inlet manifold size, is yours the 40mm? if so the bigger 52mm works well.
@@RestoDesignsnando yessir, 50mm getting slapped on soon along with an ABF clone intake cam. thanks for the advice.
@@6ixthstage845 Any time friend, are you in the states? KR inlet cam works well and matches the ex cam, ABF inlet with the 9a/KR ex cam is a bit of a mismatch setup, you'll be better off fitting both ABF cams in my opinion.
@@RestoDesignsnando I got a good deal on the cam unused and from what I read should still expect an 8hp gain from it over the US cam + more when matched with the 50mm intake manifold? will let you know how it feels when I get it all together though.
@@6ixthstage845yes anything is better than that 9a inlet cam LOL cool, I wait to see your video.
Did you do a video on how to mod the air box?
I haven't, I do show the airbox in the mk3.5 cab ABF project. After looking at all the airboxes from 1.4 to VR6 to TDI, I start by getting a mk3 TDI airbox, I use the lower half due to having no hot air feed from the exhaust as standard and having the biggest front pipe, then I use the TDI velocity stack as it's bigger than the standard ABF one.
Any gains noticeable?? Removing this lip made the car run a bit rough on low rpms??good job!!
Thanks for your support friend, yes a noticeable difference in 'tip in' and feels a lot stronger past that 16v cam point of 4k, I done this to loads of ABF's with no ill results, what engine did you do it to?
@@RestoDesignsnando in the past i do in a PSA 1.6 engine, but now the story is different i have a 1.8 Short Block Kit Car base stroked to 2.0 with stock ABF head and schrick cams, originaly this engine came with ITB but in a street car is better to use a std intake due to low end torque, perhaps i’ll try with your method but i’m afraid because there is no spare parts of this engines, they’re too old😂
@@xaakixan yes parts are becoming hard to find for the ABF, Schlick cams Cool! which ones 260 or 268
@@RestoDesignsnando 268 a bit rough at idle but fine!
@@xaakixan ok nice, you still using the standard Siemons ECU? if you are using the standard ecu and 268 cams then maybe you shouldn't do this to your throttle body as the ecu will be going nuts with the drop in vag pressure due to those cams and light throttle openings
Do you know if these samco intakes will fit a mk2 abf? I notice yours doesn't have one fitted and using a standard intake?
The answer is I don't know, the only reason I haven't tried yet is that I'm waiting to get my first 3D printed airbox to test, put it on the rolling road and do a step by step to see what does what, but that may only happen how in late 2023.
@@RestoDesignsnando it's a £90 gamble I guess. I'll let you know if if I buy one before you 👍🏻
@@ianmcmullen8535 Sounds like a plan👍🏼
Hey just wondering how hard isit to remove the throttle body?
It isn't that hard, two plugs, 4x 5mm allen key bolts and the main intake pipe.
do you still answer these?, what's the name of the cutting bits in portuguese? i tried to find them but i'm going mad trying to!
Hi there, Sorry unfortunately I do not have no idea what they are called in Portuguese.
@@RestoDesignsnando ah shoot, i found something that i think is similar but no idea if it'd work, i think its called a "fresa rotativa"
I would like to see a dyno with stock tb. with polished one like yours and with one ported and polished. So we can see the differences in each one.
Let's see how much time I can get at Stealth to play around with a few bits.
Would this yield noticeable results in an 8v 2.0?
The 8v AGG/2E throttles are smaller as are the humps, it will sharpen up throttle response, not sort about any gains, as the 8v is limited in other areas, cam, exhaust ports on the head.
Any tips on doing a mk2 golf 8v kjet throttle body?
Yes I do have a tip for you, I can't remember if the mk2 kjet throttle is the same size as the mk1's one, if it is then find yourself an Audi 2.2 5 pot kjet throttle as its bigger, you will need to port match the inlet manifold slightly due to the second butterfly's bigger size, also do the WUR mod to add a little extra fuel. Back in the day all us mk1's boys bolted on the 2.2 throttle and the WUR from the same car which used vac much like the 16v ones. Worked really well.
Where did you get the intake pipe from?
Got that inlet pipe from Samco, comes in the few colours.
Is there something similar for the 8v 2.0?
The later 2.0 AGG has the same kind wedges but on the smaller scale.
HAVE YOU NOTED IMPROVEMENTS?
Yes throttle 'tip in' is a lot better and once the 16v comes on 'cam' @4k feels better also.
@@RestoDesignsnando if I make this change on a totally original abf engine, since it takes more air, do I have to remap the control unit or make some other changes to get more petrol through?
@@cianfran93 VW drop in more fuel over 4k to protect parts, cat, valves, at full throttle, but they over do it, to the point taking a little fuel out adds power. So this kind of does that by having a little more air leans out the AFR's a little which then gives a slight hp gain.
@@RestoDesignsnando so by making this change, I do not touch the control unit and I do not do damage even if more air enters?
@@cianfran93 yes as it isn't like you are adding 20% more air, VW put that in the throttle to sorted the 'tip in' feel and in doing so also limits the top end a little. Plus the basic Siemens ECU will adjust a little to also help. Just be carefully not to touch the area where the throttle closes ok.
