Title: intake manifold for a gtd
Post by: ikas on March 07, 2009, 11:53:54 am: I've read some where on the net that the secret to have a nice power on the TD vag motors its a good intake manifold!
I wonder if exist some intake on the marcket or only we can make a home intake manifold

thanks!

that and a good exhaust manifold/downpipe can give some very excellent results!

From what I have heard the big downpipe and exhaust is a much better upgrade to start with just like jt has said. For big HP numbers though all here say to use a custom intake, so the #2 and #3 cylinders don't get more air than the other 2.

nice forum hey?

well, someone in this forum has a 1y intake manifoltd in a 1.6td, it´s larger and it takes the air from the left, ( right and of the car).
And its got a cool design too 8) .

In this forum we can see some extraordinary car and mod´s, and they are mine inspires!
And I'm remember mine poor english to get on CFS!!

Post by: dieselherb1 on March 07, 2009, 05:22:02 pm: Will the N/A intake fit next to T3 to make a custom intake? Or will any intake fit next to a T3 with trapazoid mount? A K03 seems like it would fit with exh. manifold flipped, but would the downpipe be a problem in a MK1? I thought cut a N/A intake at the pipe merge into the airbox then weld a plenum tube on, but looks like no way with a T3 trap. mount.

a spekar dessa maneira nao chegas lá nao :lol: :lol:

the 1y manifold has you all can see, is not as narrow has the gtd one, so in order to make it fit in a gtd, you have to get a tdi exhaust manifold and adapt the gtd trapezoidal flange.It´s a very insteresting setup, I think there is a user in this forum that has a setup like this...

But there is always the passat tdi b4 (i think) manifold, as narrow as the gtd and is inlet is faced right.

Post by: Rabbit on Roids on March 08, 2009, 01:20:19 am: ive got a gasser intake on my car. i think i actually gained more power from that then i did putting a big exhaust on it. its just like the intake from a 1Y engine. shaped just like it and everything. i ported it a bit too before i put it on also. they definently dont clear turbos without the proper manifolds and/or clearancing of the manifold.

What did you have to do for clearancing? Got any photos?

Post by: truckinwagen on March 09, 2009, 08:56:04 am: I don't have any photos, but I just put a gasser mani on my 1.6 head.

you have to grind around the ports on the exhaust mani so that the bottom of the flange looks like the top(tp clear around the intake ports)
and then you have to grind off the two ribs cast into the bottom of the manifold that go alongside the turbo mounting bolts.

after that, its a breeze, but you have to remember to bolt up the purbo before you install the manifold on the head, because the intake is in the way of getting the bolts for the turbo in.

Post by: truckinwagen on March 09, 2009, 08:57:33 am: the other issue I have run across is that by flipping the exhaust manifold it puts the intake for the turbo right in the way of the shifter linkage, so I will be doing some creative bending and reshaping to get it to work.

Post by: carrizog60 on March 09, 2009, 11:56:48 am: dual plenum manifold is the best as i read...
Title: intake manifold for a gtd
Post by: Rabbit on Roids on March 09, 2009, 01:04:30 pm: as close as i can tell, the DIGI 2 manifold im running is very similar in design to the passenger performance intake. its not shiny or tig welded, but it has nice big runners, and a big, open plenum on top. it works good.
Title: intake manifold for a gtd
Post by: truckinwagen on March 09, 2009, 01:44:22 pm: just as a note, all the gasser intakes(as far as I know) require flipping and clearancing of the exhaust manifold.

and all of the gasser manifolds are light-years better than the TD ones

Post by: Rabbit on Roids on March 09, 2009, 01:48:32 pm: score one for the VNT! i kept my turbo just like its supposed to be. its close tho. would have been alot easier without the egr port. am still thinking about cutting it off. and welding it closed.

Post by: Rabbit on Roids on March 09, 2009, 02:38:02 pm: so, this is a little off topic, but how did you lift your rabbit? my rabbit sees as much off road driving as it sees on the road. ground clearance is alright, but theres been a few times where 8 more inches woulda been ***in'.
Title: intake manifold for a gtd
Post by: dieselherb1 on March 09, 2009, 04:10:34 pm: How about the 1Z exh. manifold with either a K03 or T15. Turbo is on the bottom of the manifold. Also I have 89 Jetta N/A it has a intake similar in shape as the older N/As but it has a plastic airbox. When you take the airbox off, there is thr intake runners(flat surface) I thought maybe a 2-3" square or should it be round tubing welded across the runners(ported to match runners) and feed it from IC or turbo. Do you know the manifold I talking about?

Post by: truckinwagen on March 09, 2009, 04:32:58 pm: my car was lifted with spacers under the rear spring perch and cut down jeep cherokee springs up front.

later this year I will be putting adjustable height coils on it with custom plates made to relocate the strut tops lower so that I can adjust the wheel weight bias and height for rallycross
Title: intake manifold for a gtd
Post by: Rabbit on Roids on March 09, 2009, 06:04:45 pm: so with the jeep coils you still used the regular strut towers right? and how big of tires did you put under it without rubbing?
Title: intake manifold for a gtd
Post by: truckinwagen on March 09, 2009, 07:03:52 pm: I never ran tires any bigger than I could before lifting(mostly because I bought brand new tires before I lifted it and was too poor to spring for a new set before the ones I had wore out)

but you should be able to run a big tire, the only rub spot that might be a problem is in the rear of the fenderwell when turning full lock

Post by: ryanp on March 14, 2009, 03:44:59 pm: 1y manifolds are easily the best, although you wont fit a t3 near these! with a VNT you would have the best setup!

I've got both for sale!
