Thread: Finally decided that I am going 20VE. Dynoed good curve but not so impressive hp.

its definitely a 1mm metal. let me see if i can get them to take a picture and post it over. ok, so if the N1's are in, what are the cam degree angles? where did you source the VET gasket? we have a supplier here but with a 1.3mm metal gasket, pointless, which also has a stupid price tag on it. typical.

i feel like i am effing the dog here, i have done tons of research, but keep forgetting the related threads! I wanted to know what cam angle degree means i.e. +5,-5.

+5 = intake opens 5deg After TDC?
-5 = exhaust closes 5deg Before TDC?

Whats not helping is there is no conclusive evidence (well i cant find it for sure) that N1 pistons will clear the valves. There was also posts abt 16ve pistons valve reliefs being deeper than the N1s.

Whats not helping is our weakening currency! The imported header and pistons ideas have been scrapped!

Let me put this to rest. The 20V/20VET 3 layers metal head gasket is thinner than the regular graphite 20VE. How do I know this you may ask. I actually drilled out the rivets on the 20VET gasket, separated the layers and measured them with a micrometer.

20V/20VET:

1st layer: .012"/.3mm
2nd: .020"/.5mm
3rd: .012'/.3mm

Total thickness = .044"/1.1mm



The regular graphite 20VE gasket has a crushed thickness of .050''/1.27mm. I measured two used gaskets around the fire rings. The thicknesses range from .050"-.052".

That's what I've been running. Been running larger cams than N1 with N1 pistons. You are good to go.



As to the pistons with the most valve reliefs. Here is the ranking. I actuallly measured them, none of this "I read stuff on the internet".

Starting from least to most valve relief.

20V
16VE
20VE
N1

Thanks @KillerKrossover! You have not only helped me but helped many others who are puzzled as well! A virtual pint on me!

Now, what metal gasket does @sss4me have then? since he is saying his is a 1.6mm VET gasket?

I really dont know how else to thank you for this @KillerKrossover. Many would be grateful!

So just for some comparison data, what kind of gasket thickness are you running and what are your cams degreed at?

I can't speak for sss4me but I believe he just measured it differently, if he measured it at all. The 20V/20VET gaskets are embossed on two of the outer layers so if you don't separate the layers and measure the flat areas, you're not going to get an accurate measurement.

Since multi layer metal gaskets are embossed, you have measure them on the flat areas. The Cometic Gasket technical rep confirmed it for me when I called to inquire about their selection of gasket thickness.





My little secret. I actually removed one of the layers from the 20V gasket. So I'm running a tight piston to head clearance, sort of pushing it.

For cam timing you really have to degree the cams with a dial indicator and degree wheel. It's very technical. Since this is not something you can just jump into, people just install the cams "straight up" or install to the factory marks. When someone mentioned installing the cams being installed at +5-5, they are saying they advanced the intake 5 degree and retard the exhaust 5 degree from factory straight up timing.

my sincere apologies if my info was wrong. six months i had my metal gasket ready to go, and i never measured it properly. i always thought though (and there are numerous threads on here too) saying the metal gasket is 1.6mm. even the maxworx's site USED TO state that. today i look it up and its 1.1mm, and i'm like mmmmm. genuine part number is 11044-8H600.

"killer crossover" is the man with this stuff! i have no clearance issues with my setup, and am looking to go more with kelford cams soon. he has already used kelfords with the same setup. you will have no issues.

Yeah, we've got all that and will be setting as per say. Just was a little confused with advanced and retard.

We've ordered another multi layered VE metal gasket locally (this was like almost triple the US price) and will be derivetting mine to use the middle layer for a total thickness of above +1.5mm. That should bring the compression down.

thats great! kelfords will be my next option. once $$$ permits! Let us know what your results are like!

I was looking at your compression test pics, you were getting abt 270psi rite? doesnt that work out to 12.8:1ish?

Hey Enzo,

Ok, we got everything connected to the car already,Nismotronic is fired up and running well, but the car is not firing up. initially we had a problem with the CAS wiring which when cranked up, showed 16000++rpm. But we reversed the wiring for 180deg and 1deg now it's all good. Shows cranking at 220rpm.

The problem is now I am not too sure why aren't the injectors supplying fuel. Yes, fuel pump is delivering to the fuel rail, we are getting ignition, is just that the injectors are not working at all. How we know this is because after abt 1hr of cranking the plugs are dry.

When cranking, the live data shows that the engine in cranking, fuel pump is active, injector duty has values.

I am using a GTIR ECU, 20VE Dizzy, 20VE Maf.

What base file did you use?

So close yet so far.

Do you think you could help us out? Tried to pm you but inbox is full
