Deck Height of Early 1.6 GTI Block

Hi all,

Does anybody know what the deck height of an early "EG" code 1.6L gti block was? Is it 220mm like a 1.8 block?

Thanks for any help,

N.

 

I am pretty sure it is. The EG engine is pretty unique in VAG big block with the use of a flat head and chambered piston for the combustion chamber (heron design). This limits cam selection due to clearance issues at the overlap point.
Nothing of use in here?

Thanks for this. I just checked, unfortunately nothing concrete in there...

 

Is this for an Oettinger head out of interest?
I was always interested to see how the headgaskets varied on them on the early 1588cc engines and later 1595 and 1781cc ones.
There are a few differences in the crank stroke and crankpin diameter between the early and later engines.
If you are building something bespoke let me know, as I have built a few "unusual" versions with different rods and pistons. Got a lot of options available now.

 

confirm it s 220mm if you can find a H block it s better

the oettinger head gasket is a standard 8V 1.6 with extras holes drilled in to it for better cooling
the standard 1.6 EG head gasket is the same as the 1.8 DX whithout the extras holes drains

 

Thanks guys,

I'm just doing some preliminary investigations at the moment, and trying to work out what block was used with the Graf head that I have that dates back to the early 80's.

 

What's the chamber volume of the Graf head? That should give you a good idea what block/piston setup was used.

 

the H block was used by oettinger and VW motorsport
that s the one you want if you built a 1.6 based engine

@mike if I m not wrong the chamber is pretty deep on those those they almost look like
old alfas or porsches combustion chambers (with the extras valves)

 

What 1.6 though, 1588 or 1595cc?
The 2nd having a bigger bore and shorter stroke.

 

I m talking about the old 1.6 engine type EG
79.5x80
if I m not wrong you compare the MK1 and MK2 1.6
when I say 1.6 based I mean those old head : graff , oettinger , drake
were all based around the MK1 1.6 GTI engine type EG
there has been TWO block s at those time the 1.6 stamped
and the H stamped which was also called chrysler block
which was fitted on the homny or omny in state
the H mean henceforth and it the best one to fit on one off those engine base
*can be bore up to 83 mm
*can receive up to 94.5 mm crank more room then the standard 1.6 stamped block
hope I made sense...

 

Yes, I understand Romain.
It is just there a few options for building various 1.6 engines with different strokes, rods and pistons.
Something that folk should understand before considering which way they want to go.
Fitting a 94.5mm crank is not going to make a 1.6 engine though. It will all depend on what the engine is being built for and the class structure if it is going to compete in events.
I have seen Oettinger heads on later blocks so wondering why the OP asks about the 1.6 EG 79.5mm and 80mm stroke engine.
If sticking at 1.6 there is a 73.4mm stroke crank. A large overbore and this could still stay under 1.6 with a well oversquare configuration.
Or there is also a 77.4mm stroke crank too.
Many options.

 

you could fit an early 1.6 based cylinder head ( graff , oettinger , drake )
on 1.8 or even a 2.0 block you have to make it fit
plug the second drain hole from the block and you are pretty much done

I just mention the 94.5 crank for the infos but I definitly wont fit that for a 1.6

I am with you regarding the different option off crank and I too will go for a shorter stroke
some sort of berg cup crasy high revs engine

I was just exposing the better block and I forget to precise that VW motorsport was using the H block on their F3 engine

 

Hi Mike,

Not quite that simple, it came with some domed forged pistons. The thing that points to an early block is that it also came with some 136mm rods, this was pre G60 days so I assumed mk1 1.6 gti..

 

Yes, that makes sense, thanks. Can you tell me which cars this was to be found in?

 

Yes, all information much appreciated. This is the very early stages of investigation at the moment. With the Graf that I have, if I am to build it up, I would like to retain some level of originality hence the detective job on what blocks were used...

 

This block was found
On some standard 1.6 GTI
On chrysler homny or omni
They were call in states the 1.7 engines
Or on the french oettinger 16 soupapes

 

So essentially where the UK is concerned, EG Mk1 GTI 1600 blocks.

Finding this 'H' block I would imagine is not easy? Even in France? Romain?

If an EG suits, Neal, I know where there is one.

 

well that s the thing
I eared of people on the french forum
that had the H block on their standard 1600 GTI
so yeah it s some kind of lottery
but if you find one it s the best one
I knew off a place were they were selling brand new H block in germany
need to find it again

 

It would be interesting to see this 'H' block Romain.

If you are saying some Mk1 1600 GTI 8v cars came with the H-block, this means some EG are 'H'?

Are there any pictures, showing how the 'H' is at an advantage compared to a non-'H' EG?

 

oh boy.... if only i had my car here you ll have plenty of pics
hopefully couple of month or less dont which to anyone to loose their wallet
not even the money but all the papers driving licence , carte grise ( french V5 ) , and bloody passport
which mean I am stuck here and cant bring the car with me

no the EG block are normaly 1.6 stamped blocks... I know it s pretty confusing
when I found that SOME standard GTI 1.6 (EG) were fitted with H block to I to was a bit lost

no havent got not pics showing differences but severale texts
from roberts collins (ex drake )
and heared from different people
I do not have a 1.6 stamped block to compare with the H block
