So, finally getting going on my dads car, he purchased this "newly rebuilt" 2.0L a few years ago. Its been sitting covered in the garage for at least 2 maybe 3 years now so before we throw it in the car I decide to at least pull the heads and see whats really in this thing. From all indications it seems to be a pretty fresh stock rebuild.

It does have real 2.0 heads, it didn't have head gaskets but it did have a single shim inside each chamber (I guess to lower the compression even more, I forgot to measure the thickness)...

The pistons have a pretty healthy dish in them that I don't like. What are a set of euros going for these days? Or how bout a set of 96's? Is there a way to tell real german cylinders from others incase I want to get these opened up?

and I did some very crude measurements on the cam, is this anywhere close to a real cam?
exhaust: .326 lift and 180* duration
intake: .326 lift and 225* duration
these numbers are no where near being precise, but I am hoping close enough to tell if its a stock cam or not...

The car is going to have dual webers and is goinig in a street car, so don' t need anything crazy, I just want this thing to run well. I am probably going to send the heads off to Jake/Len to make sure they were put together right, and maybe change the pistons out to bump the compression...any further suggestions?

on to the pics:

other side...nice dish!

lifter shot...I guess since this engine was put together several years ago these are the good ones?

cup - I messed with this one so you could see in the cup...looks like a single piece unit...

Looks to me like stock 94 U.S. pistons.... You can double check but the cc of the piston dish will be like 5cc.
You can measure deck hieght and figure out what you compression ratio you have. Of course you need the cc of the combustion chamber too. Looks like the heads were sealing pretty nice. Lose the shim inbetween the cyinder and the head. Just lap the matting surfaces.

I know nothing of cams but that seems aweful small (mild). my cam measures .500 lift and 290 duration. That is the other end of the scale.

the pistons look like low compression bus pistons ( ) ...

as for the headgasket/shimms ...

don't use any headgasket! the shim (to lower the compression) is supposed to go *under the cylinder*, where the cylinder meets the case, not between cylinder and head.
anything you put between cylinder & head will make it leak.

don't do that unless you have a Cam that is beneficial for carb-use. with the stock FI-Cam, you'll have no additional power but a *much* worse gas-milage!

i'd say get yourself a nice set of euro pistons!

Dibs on the "bus pistons" if you decides to go to with Euro.

Dude-what is that stuff all caked between the middle lifter valleys??? That looks kinda like JB weld---investigate that please and let us know-----

I think I have a set if you want them.

Wow...this dropped to the second page fast...the mess between the lifter valleys is just the left over from a mud dobbers nest, not to worry.

I do believe that these are lower compression pistons than the US 2.0L pistons as I saw a set of those recently and they definately have a bigger dish than those did, so you are probably right they are bus pistons I assume.

The webers are not an optional issue, thats what this engine came with and I don't have any Djet knowledge, experience or parts...

While we are talking about injection, anybody have the specs for a stock cam? these anywhere close? I tried searching but didn't come up with anything solid.

McMark..PM me with what you would want for that set of pistons...

Thanks for the help...

Pop off the oil pump and see if there is any numbers on the cam, near the oil pump drive…also see if it’s a bolt on gear.

Hello,
0,326" is about 8,28mm cam lift and this is not stock. Stock is even less cam lift.

The 0,500" lift s/body mentioned is valve lift. Divide by 1,3 appr. and you get cam lift.

The pistons look like the low compression cheap bus pistons to me. I agree, loose them if you can afford it.
Otherwise a nice fresh looking engine to me but only accurate mearurements could indicate a complete verdict. We can only look

Greetings,
Walter

Way to go Walter. I was wondering when someone was going to mention whether the lift was measured at the lifter or the valve.

Yeah...my feeling as well....Bus pistons. Fill the dish with JB Weld and slap em back in....

Ahh...I should have mentioned that this was measured at the lifter using some electronic calipers as a depth gauge while I spun the motor by hand, and we were getting a pretty consistent ~8.3 mm of lift, so I think these numbers are pretty close, but by no means precise.

What is the "proper" way to measure a cam then?

I will pull the oil pump next time I am over to check the end of the cam to see if there are any markings.

Thanks for the help guys,

Tony
