the Official 16v thread

[aliasmk2]

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

[twin eng, twin turbs]

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!

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.

may we see some pictures!!!!!!

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.

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

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?

[WABIT]

im definetly in for that 100%

get in contact evorobin!!!!

No radial firing order???

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??

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

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..

[Valver.]

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

You'd be surprised if you put an old, unrebuilt 9a with KR or ABF cams on an engine dyno. Not only are the cams alone not worth a 20bhp+ increase (you don't get that in peak figures moving from PL/9a cams to Schrick 260s), an engine with a quarter of a million kms already won't make its standard output.

Fair enough a lot of the UK cars "have" blaring hp figures, but no one has used a proper engine dyno, and I'm sure if someone was to put a genuine, fresh 160/170/180hp engine in their car, they'd be very surprised.

A 172hp Clio has miles more grunt than some of the VW 16vs I've driven claiming similar outputs - same, too, with the 168hp B16A Honda, which has far less torque. I'd be more inclined to believe a 15 millio dollar factory dyno than "Vince @ Stealth" with regard to how much power my engine had

Not intended to be a blunt post, but if people are to learn from this thread, let's a least be a bit realistic about how much power is reasonably achievable on all but a massive budget

And even so, 16vs are nice to drive for their torque figures, which can be boosted up nicely in the mid-range with tuning... far more important in a road car with sensible gearing and speed limits.

[GoLfMan]

so basically are you saying a hot 8v can achieve nearly the same amount of HP for less dollars?

A hot, well setup 1.8/2.0 8v could definitely challenge a higher mileage, standard 9a 16v IMO, yes It's all a bit subjective still, though!!

EDIT: But tuning the 8v to do so would cost more than a reasonable 16v swap...

This isn't actually a manifold for any VW that I know of.

I have built a MK1 16V using one of their manifold, that was in 1996 and I don't think the price has gone up since then!!

They don't look like a Supersprint but do the job for less money.
