The Problem in the Ebay exhaust is, that the Downpipe is missing (connection from exhaust manifold to catalyst) and the quality looks very bad
Look at my exhaust on a NG-Engine an the direction of the downpipe!



The problem that you have is, specialy in a typ89, the install area is very close






The Power"boost" from about 15-25BHP only with exhaust is complete ridiculous!

Haha, yeah a 15-25HP increase sounded a bit exaggerated! It seems that the Quattro 3 stage ex. maifold is a hard piece to find. Are there any other alternatives? What did you use?

Best regards

Hello again.

I bought som pistons for the NG engine:

Rodlength: 144mm
Piston diameter: 83mm
Compression: 10:1

Part nr. Rods: 035 198 401 C
Part nr. Piston: 054 107 081

If I bore the engine to 83mm and use these pistons, can I still use the KV cylinderhead, or do i have to find a NG cylinderhead?

- Karsten

Hello again too !

Valves (40mm/33mm) and Channel (Inlet/Exhaust) are in both heads the same, you mustn´t change from KV to NG!

The the position of fuel injectors are different! In the KV Engine are the injector fitted in the cylinderhead and in the NG engine the injector are fitted in the airintake manifield!
If you change the the head you must be change the manifield of NG too or modified the KV once.

Why did you need new pistons? Compression problems?

The only reason i wanted to change the pistons is because I thought it would give a performance boost if the engine bore was increased from 81mm to 83,01mm? I bought the pistons and rods on ebay for almost nothing (2,5?), and they are in good shape.

It's my first time renewing/tuning an engine so maybe I'm mistaken?

Yes, I read that in one of your earlier posts

The valves on my KV engine are 38mm/33mm.

I thought you guys said earlier in this post that the the first NF and the NG cylinderheads had 40mm valves?

- Karsten

Thats true!

Thats a Cylinderhead from your posted page



And that was my Lastyear-NG-Cylinderhead with stock valves, but head highly modified (e.g. bigger channels, compress ratio 11:1)



You can see the different between the valves!

I can tell you (or recommand), that will give a better effect and more punch, when you modified the head (change to 40mm inlet Valve from NF1 or NG1 with Manifield) and change the cam to a 272 or 276 degreese, manufactored by dbilas dynamcs or schrick at first!

Look the different between your channels and my, tuned by dremel





My cylinderhead (intake insize over Valve 38mm) is for 82,5mm Pistons to small an makes vacuum over 5500 RPM!

Look the acceleration fromm 100 to 200 km/h! Safe the Money for pistons and buy head tuning

Ok, just to get it right. If i wanted a increase of power to 160+ i would need the following

1. Use the existing 81mm pistons
2. Get a NG or NF head with 40mm valves
3. Modifiy the cylinderhead. Polish etc.
4. Schick 276 camshaft

5. NG intake manifold.
6. For starters use the K-Jetronic CIS
7. New springs and retainers
http://www.034motorsport.com/product_inf...products_id=527
http://www.034motorsport.com/product_inf...oducts_id=13255
8. Increase compression to 11:1 by surface grinding the cyl.head
9. KV Quattro 5-3 exhaust manifold.
10. New waterpump, gaskets etc.

Basicly like you said, use most of my money on head tuning.

I'm sorry if you guys already went through all of this, but my german is really not very good.

Exactly!

If you are looking for cylinderhead, watch out for a NF1 Serien, they have the same Airbox Manifold like yours, but with 40 mm Valves

to 3rd. mod the head clearly and check out, that the 5 combusition sections have all the same volume level (very importend)



Open the valve seats inside to 35-36mm (stock 32,5mm)

to 4th. thats the official buyers price, thats ok!
to 5th. If you use a NG manifold you need plastik covers for the injectors (i´ll sell my on Ebay soon ).
to 6th. that will work if you can do to adjust the K-Jet
to 7th. isn´t required (stock valve springs and retainers are complete adequate)
to 8th. very special! try only the multilayer steel headgasket from ADU Engine (install it exactly). i think, thats is much enought at first!

other recommands: buy a 200cpi metal-catalyst and a bigger exhaust to the end (complete in 60mm in the best). install a 60mm connector on the quattro exhaust manifold and go with 60mm into the metal catalyst. if you have less the 60mm (inletsize) in this section you loose Power.

For me is that english course good practice test.

your welcome

Have fun by tuning!

Hello JoeDalton!

Good that there is someone who als has a KV-engine.

I have followed CoupeBerlin's instructions for buying new parts and that are the right one. The NF1 cylinder-head fits exactly with the original intake and has the bigger 40mm valves.

So you should get a good tuning-result for your engine if you build up your motor like you described it!

I only changed the old KV-cylinder head against the new build up NF1 with some special extras like you mentioned and get a real impresive result.
My friend and I who build up the new NF1-head had newer thought that this will get some extra power into the old PASSAT 32b in this way.

Super! Thank you very much!

I'll try and get me a NF1 cylinderhad and follow your instructions!

What year is the NF1 cylinderhead? 1987?

Luckily I'm not required to use a catalyst in Denmark because the car wasn't born with one to begin with. 60mm sounds like a good idea. I'll have that in mind .

Haha, yeah neither did I. I've always liked the fact that the 32B is built on the same chassis as the Audi coupe (VW B2) and therefore is somewhat of a misfit. The ultimate goal with the car is to strip it down as much as possible (maybe 875kg) and with as much power as I possible. I Denmark we have alot of strict rules regarding engine tuning.

- Karsten

Long time no see!

Just wanted show of the KV Quattro 5-3 manifold i found. I have compared it with my current existing 5-2 FWD exhaust manifold.



If this is the one, then let his be a reference for anyone who wants to find one by themselves, but don't know what to look for.

- Karsten

P.S Still looking for that NF1 head!

Hier noch jemand aktiv ?

NG und AAR Nocke identisch ?
bzw. eben KV Nocke steiler als die vom AAR ?

die Coupe Berlin Website funkt leider nimma...

Grüße

Ok das halt ich mal im Hinterkopf, falls doch nix wird mit AAR Nocke auf 276° umarbeiten (dbilas).

Fährt hier jemand 276 oder ev. sogar 280 oder steiler ?

Funkt mit der KE III ? wie ist Standgas usw..

Grüße

Ich fahre eine von dBilas auf das 272 Profil umgeschliffene Welle im NG und bin ganz zufrieden. Standgas ist super, auch in Verbindung mit erleichtertem Schwung. KE hab ich selbst eingestellt.

Habe allerdings noch mehr am Motor geändert.
