the Official 16v thread

Do you mean tuned lenghts.
Never heard it put that way. But I imagine they're not just bunged together any lengths.

And YES WHEN AND HOW MUCH??

No, i mean radial collector. In the order of 1,3,4,2. One after the other..




Oh, and i need a short block 16v one to suit a Mk1..

[roccodingo]

Thats the same as what I run, (fly, exhaust, timing) except mine has twin 45 Dellorto's, and I use the early ecu, supposed to have a more aggresive timing curve.

You need to bring that out of the woodwork Ian, where you hiding in perth man

[ausgolfer]

No radial firing order???

im definetly in for that 100%

get in contact evorobin!!!!

4 branch Manifolds (Exatractors) make one hell of a difference!
Esp at the top end where a 16v tends to live most of it life.
My mates 2.0 16v GTI Egnineering jetta had a polished and ported standard cast manifold and he was told that will do him. After alot of playing about he later changed it for Ashley manifold and gained 10BHP @ wheels and broke the 190bhp @ flywheel.
He now fits them to all this 16vs builds (he has since built 2 mk1 16v's)

Anyone else fancy 16v header group purchase?

Being the the Official 16v thread thought id ask a question im running a 2.0l 16V (Audi 9A 2.0l bottom end with VW 16v head) im after a new timing belt does anyone have a part number for a timing belt??? (beats taking it off and sending to my parts guy)

Im running K-Jet, lighten fly, custom extractors, altered cam timing and 50mm intake and all it does is spin wheels i put in a locked diff still spins wheels 3rd gear is where i get traction and changes lanes in the process back yard tuning has worked good so far like to dyno it to see some numbers.

not that it matters much but the Audi is 6A not 9A,(9A is passat/corrado)

The part number for the belt is 027 109 119 C (25mm x 1176mm)
I would replace the tensioner aswell, Part number 051 109 243

Hope that helps

may we see some pictures!!!!!!

Audi A4 btcc touring cars had 2L 16v engines in them 96 on I think,
depending on the year these were either 295 or 305 BHP,
These engines are N/A,
From what i can find out they are basically 6A engines, solid lifters, big cams, throttle bodies, they produce max power at @8500rpm,
In my opinion these are the ultimate 16v engine, imagine this in a stripped mk1/2 gti

That 16v is sex on wheels! omg. looks like slide throttle bodies aswell!

All very true comments, and in a straight out and out performance comparison, yes, the old 16v would get flogged.

But the fact is, we aren't racing these engines in a very restricted class and horsepower is only beneficial to a point.

This thread was started so that we could discuss the 16v engine in terms of performance modifications, general servicing etc.

So let's not get into a discussion about how bad the engine's design is or the fact that a 10 year newer engine has a better design.

Its all knowledge guys, you have to take the good with the bad

[velly_16v_cab]

you will get that from a STD 1.8 KR valver,

155-160 for a std 2.0 would be ball park, i think Dom is on the right track

[Valver.]

yep, its a thread about make do with what you got! it is said on many build projects in the uk that a 9a with KR cams is said to put out inbetween 160 and 165HP

dom

In reality, they'd have about 140/145hp - perhaps less now that they're so old
