gasser manifolds

[danwithagolf]

What gasser manifolds fit on the 1.6l n/a i see tons of 1.8l gasser 8v in a auto wrecker do they fit? i would guess a 1.8 manifold would flow way better and i could pick one up for almost nothing

[burn_your_money]

Any VW 8v manifold (intake or exhaust) should have the same bolt pattern as your car. ABA intake manifolds may be excluded from that group and I don't know about the mk4+ engines

i have the intake and exhaust manifold from an 86 jetta gli that iwill be installing soon. the exhaust mani is a dual dp mani and the only reason im running the gasser inake mani is cause i cannot clamp shut my n/a box with the g40 valve cover i have on there

I tried to post a question about this before, what are the advantages of using gasser mani's on a diesel? i've got a gas mkI (79) and a diesel mkI (81), the gasser is just being used for parts right now, is it worth swapping the parts (intake/exhaust mani's) over? What other parts would boost perf on the diesel?



does anyone have experience/examples of swapping a drivers side inlet gasser mani onto and passenger side inlet diesel mani? Pix, anyone?

[burn_your_money]

For intake manifolds the advantages are mainly for TDs because they have a crappy intake. On NAs it's less back pressure. Some people use both on the NAs because there is talk of clearance issues, but those can easily be ground away

i guess with the n/a's with a gasser intake you would put a short ram or a cold air intake on but in the pic above could you have the exhaust mani and the intake on together on a n/a? i would like to get both on my n/a i have a short ram that would go on that intake nicely

i settled with a gasser manifold to replace the broken oem plastic air filter housing on my 1986 n/a. because none of the local wrecking yards have diesels and the dealershops were no help at all.

i tried the short ram set-up but the intake roar was too intoxicating and it grew old on me in a few days. so i added a 2.75" extension and relocated the air filter behind the passenger headlamp, and also made a heat shield.
it totally eliminated any offensive noise and i can now carry on a conversation with a passenger without shouting at each other

nice back yard engineering  :lol:

I wonder if we could do this by flipping the exhaust manifold over and redoing the oil line, oil drain down pipe.

It would be allot of work but much better intake.

That's how it's done on a gasser using TD turbo. Gotta flip the exhaust manifold, clock the turbo so everything is right side up, fab a downpipe, custom oil feed and drain lines, custom turbo intake... It's not that simple.

[gigaz2]

you mean using a TD manifold.. as a TD turbo might melt in the gasser application. EGT's are way higher.

EDIT: been studying this to see if I could use a TDI T15 to turbo my 1.4 gasser

back on topic: new style turbos (TDI) already have clearance for decent intakes, I guess VW sticked to the old design for cost reasons

I mean the entire setup minus the intake stuff. I doubt the turbo would melt, they're not as sensitve as VNTs. But the AR ratio isn't good for a gasser anyway.

[jtanguay]

i think balancing the pressure to all 4 cylinders is a main benefit... everything else is gravy    the stock TD manifold biases the two inner cyls...  but some will argue that with boost pressure, that doesn't really matter...  i think it does matter to some degree, but what do i know  :lol:

Just put it in a longitudinal car. It makes the gasoline intake manifold upgrade easier

so dieselwagen the intake mani you have what motor is that off of and what year car? i went to a auto wrecker the other day to take a look and i see tons of 8v 86-92 golfs and jettas your intake looks a bit diff tho. thanks dan
