How long will your conrods be? What pistons pec do you have?

Can you provide more infos on the Head studs?

The Copper head gasket is better than the original?

[kalsket]

AFAIK Multilayer steel gasket is better than Copper gasket

[Volvo 850 S2++]

My conrods are 158 mm c/c and 22 mm crosspin. And that turned out to be a problem, since the JE pistons are made for 20 mm crosspin
I'm not too impressed of my piston dealer (not KRB). Not very many of the measurements on the pistons turned out to be what I asked for in my order. I asked for a 81,5 mm bore, but got 82 mm. I asked for 22 mm crosspin, but got 20 mm. Fortunately it was not vice versa. Some 20 mm bushings and 0,5 mm bigger bore later I'm on track again

I use the original tdi multilayer steel gasket. It is both better and far more expensive than a copper gasket

PO rods are made in Finland by Pasi Ojennus.

I stock them too. 215-225 eur / piece incl 22% vat.

e: How much do Stenparners weigh?

[Billman]

So you are saying that the best option for a head gasket is the Audi 5 cylinder diesel Gasket? How thick is it? You can not reuse this gasket or am i wrong??

Are these PO Rods better than Verdi or 034EFI? Why are you taking the 158mm conrods! What is the best length? Pisobiker took 155.8mm!

[AnLe]

There are sources that say metal gasget can be reused, but there is no use to test this theory in your car. The best way is to use std audi metal gasget as you have std audi engine in your brick car.


The audi gasget is 1.61mm thick. 155.8 sounds wery good, PO's are just fine, they seem to turn into gold when shipped to Norway... Verdis are not so heavy, but it makes things more even as I use Verdis in Finland

Sorry it goes a little off topic but:
The Audi Diesel Gasket is 1.61 thick or the RS2? Witch is better? If so with 156mm conrods c-c what specs must the pistons have to make a non interfearance stroker (diesel block and Crank) engine with 8.5 : 1 CR? Head is an RS2

The lenght of rod depends what pistons is to be used.

The audi metal gasget is 1.61 thick for the petrol/bensin engine, tdi gasget is no good becouse there is few minor differencens of the oil and water lines, these differences has to be corrected to the block also.

[Volvo 850 S2++]

I have modified my head (well, not my head, but the 7A-head...). A minor weld job in one of the water lines and bigger bore for the studs. The tdi-block remains pretty original, but I might plug an oil return line in the rear end of the block. I'm not 100% sure of what gasket I use, but I'm quite certain that it is a tdi-gasket.

Here are some pictures of the differencies between the 7A-head and the tdi-block (and gasket):

How much do Stenparners weigh?

I've spoken to Sten Parner on the phone and he said that the his Audi 20vt rods (stock length) weigh 525 grams (he actually put them on the scale while we were talking).

[Volvo 850 S2++]

I guess that the weight depends on the c/c lenght, but my 158 mm PO conrods weigh 655 grams each including bolts and 20 mm bushing. Using my electronic kitchen scale, but nevertheless...
