Hi, I just purchased 1969 opel gt. How can I tell what size engine
is in it ???? vin#931787972 also has UU741 on tag.
thanks, kalen

its either going to be a 1.1 liter or a 1.9 liter if it was made in 69, chances are probably the 1.9, 1.1 GTs are rare. the biggest give aways between 1.9 and a 1.1 are size, 1.9 is alot larger, but never seeing opels before you probably wouldnt know the difference. a 1.1 will have a steel valve cover, where a 1.9 will have a aluminium finned valve cover that says "OPEL" on the front. on the drivers side of the engine there will be a number on the block, it protrudes out on its own little surface...can't think of better words, and the number will start off with 19XXXXXXX. if you can't find the number or judge by the valve cover, somebody else here will be sure to help you, and welcome to the Forums.

Congratulations! That car has a 1.1L unless someone has swapped out the whole drivetrain and suspension (unlikely).

It's a 1.1 if it looks like this:

A real quick and dirty way to see what size the engine is, 1.1 has two carbs, 1.9 has a single two barrel down draft carb. HTH.

It appears that it is a 1.1 after looking at the photo. the engine
block has the number# 118RUS0058574 OR 11SRUS0058574
and has (2) solex 35 pdsi carbs. i'm really appreciative of all the
help. thanks, kalen

THIS (11SR) says it all . . . 1.1 liter, high compression (9.2:1), (S)uper (R)allye engine with 67HP and a 3.89 rear end. As someone else has already said, a 1.1 engined GT is very rare here. Definitely restore this car to original. You'll end up with very unique Opel and be happy you did, in the long run!

...(S)uper (R)allye engine with 67HP and a 3.89 rear end.

4.11 rear end.

And yes, as Otto said, restore it to original specs! Let me know if you have any questions along the way...as I'm in the process of a GT1100 restoration, too.

Btw, what color combination is your car?

[jeff denton]

What? A 4.11 rear end ratio? I didn't know there was such a thing in a GT. Tell me how that happened, please.

[Killer Texas GT]

They put the 4.11 gear to give the 1.1 more get up and go, the gears the 1.1 Kadetts also had 4.11 gears. They won't work for the 1.9 as the torgue of the 1.9 will break em.

Not To Change the subject: I have some NOS 1.1 parts if anybody is interested. water pumps, gasket sets and...

SORRY, but for '69 model year the 4.11 rear end was used only with the Kadett 1.1SR engined Wagon and Sport Coupe (Rallye). The standard Kadett 1.1 and ONLY the GT's 1.1SR engines all used 3.89 rear ends.

As Rodney said, NONE of the 1.1 rear ends can take the torque of any CIH engine!

[kwilford]

Does anybody know of a reference that describes an Opel CIH engine by its serial number? For example, aside from the "19S" on the block, do the remaining numbers define when it was built, and any details such as compression ratio, 3 bearing head, 12 bolt head, and such? I received a e-mail from a fellow on eBay who is selling a used engine, but he wanted to know what year of engine it was when he listed it. Thanks!

I just found a gt in the junkyard that was pretty well stripped except for the engine and trans. Anyone need parts let me know.It is a 1.1 with 2 solex carbs

I have a few questions for you fellows out there. I'm thinking about installing a Getrag 5-speed into my Opel but I need to know what type of engine I have first. I own a 1973 Opel GT with a 1.9L engine. Is it possible that this motor is an OHV or is it a CIH? I can get the Getrag only for the CIH motors but I'm really not sure what kind of motor I have. Please help?

[greensmurf20]

the 1.9 is a CIH motor.

You should have a 1.9 CIH. But be aware, there were Getrags made for the OHC engines and the bellhousing bolt patterns are different than the CIH and not interchangable.

The 1.5 ('68 only) and all the 1.9s ('68 - '75) imported in Opels here were CIH engines.

[oldopelguy]

The 1.1 and it's family of engines was the motor typically refered to as an OHV motor, and this could include 1.1, 1.1, and 1.2s in Germany and the 1.3 in England in the Viva (sort-of). This motor family was more common in the Kadetts and such, and was very popular in Europe and Africathrough the mid 80's. The 1.6 litre OHC motor in the FWD Pontiac LeMans and it's family of motors have a lot in common and were probably based on this engine family.

CIH was used for the 1.5, 1.9, 2.0, 2.2, 1nd 2.4 litre 4-cylinders and the 2.4, 2.5, 2.8, 3.0, 3.9, and 4.0 litre motors of the same family. This motor family was available in Australia and South America as well, and was the base model on pretty much anything RWD in Europe, including the Frontera (Isuzu Rodeo) and the Omega (Caddy Catera) right up to the very early 90's. There was also a diesel version available in a 2.3 litre displacement that was oddly popular in England in the Viva, Frontera, and Carlton. Those would all be good doner cars for 5-speed Getrags.
