    Opel rekord b 2.4 street car project

    Hello. I'm building a 1966 opel rekord b 2 door for my very first car. My father bought this car in the 90's and originally it had a 1700cc cih engine with a small solex carb. The car has been repainted at sometime but the original color was alaska grey. Nowdays it is in pretty bad condition but it has no rust. Still has the original engine and trans but the engine has been rebuilt and bored to 1900cc with a weber dgv carb. You might be thinking that I'm going to ruin it because I will be throwing the original drivetrain out but the thing is that the interior is all gone and many of the original parts are gone so it would be wayy too hard to restaur it to original condition.

    So the plan is to make this car a good for the street. It will be getting a c24ne engine with some kind of street cam and stiffer valvesprings. The valves in the stock 2.4 head are big enough so the head will only get a mild porting. Crank, pistons and rods are all very low mileage. Pistons and rods are under 10 000km driven and the crank is about 80 000km. And to feed it all it will probably get a pare of dcoe 45mm's and a high flow exaust manifold. (Looking for around 160-180hp at the tires)

    The other parts of the drivetrain will be something like a 240 getrag 5 speed and 75% lsd differential so it can handle the power. All tho the stock u joints might be a bit risky but hey we will see...

    The car will get a red interior and a fresh coat of paint with a white/black rally color steem which was used in 1960's when these cars where used as rally cars. In sweden

    I will also upgrade the brakes because when you have that kind of power you need some brakes to stop that power. And it will also get bigger wheels and grippyer tires to put that power to the ground. I will also throw in some homemade leafspring slapperbars to elinimate wheel hop while accelerating.

    If you want to follow this project I will be mostly active on my instagram accout @fmk garage and I will probably post some bits and pieces here and in my youtube channel @FinnishMotorFreak

    In the pictures you can see the c24ne parts and the car in 2009 when it was in driveable condition

    Hey, sounds like fun! A number of people here on the Forum have put 2.4 motors in their GTs so check the Performance Forum: https://www.opelgt.com/forums/performance/ and the Engine Swap Swap as there might be a bit of help there! The last post was from another Finn and he was commenting on the C24E motor. Good luck with your build and please do send us some photos of your progress. I need some inspiration! - Doug (slracer)

    Hi Veikka,

    Thumps up for bringing the old Opel Record back on the road. I have spend a lot of time of my childhood on the back seat in my (late) fathers Opel Record b, 1900 when he was chauffeuring us from Copenhagen to the family summerhouse in the north of Jutland. Happy Days back in the 1970'

    Please post pictures in this thread from time to time, even though it's not a GT.

    Cheers, and good luck with your project.

    Anders.

    Nice to hear. I too remember something from when I was riding in the back seat. Here is some pictures of the car now with the interior stripped. The last picture is the one I would like to make it look like.

    The Rekord B is a cool looking car, and it was the first model with a four cylinder CIH engine. Originally the CIH was supposed to be launched in the Rekord C, but since the car wasn't ready yet, Opel was forced to make an interim model based on the Rekord A. By the way, both Rekords are the last models where the basic bodies were designed in Detroit and only the grills, lights and trim were designed by Opel. If you look closer you can see that they resemble a 1st generation Chevy II in profile, and that's because they were supposed to have been designed by the same team(at least if what I have read is true).

    @FMF
    You are aware of the fact that you can't legally swap to a C24NE according to the Trafi(Finnish TÜV,MOT etc) rules which say that you can swap to an engine that has max 20% more power and max 25% more displacement than the largest and/or most powerful engine in the model line up ? The largest and simultaneously most powerful engine in the line up was the 100hp 2605cm³ six cylinder Kapitän engine, which means that you can't swap to an engine with more than 120hp, and the C24NE is rated at 125hp.

    Thank you for the info. And yes I know that and I will be building it into a 1.9s block so in the papers it will be a 1.9s cih with douple carbs and a getrag 240 5 speed

    I have finally got the original engine out with the worst home made engine "hoist" ever. Now I will be taking everything else off the car (axels, electrics, other stuff) to get it ready for sanding the old paint.

    Finally I also received a reinforced clutch setup for the 2.4 engine. It is a 9 inch and it has been driven but only very little amount. The clutch plate is new since I got it so cheap from a Finnish opel freak.

    Finally got gthe axels out. They will be getting a fresh coat of paint and a 3.55 gear ratio instead of the original 3.67 for that extra speed. The rear end will also get a racingdiffs lsd kit for extra grip.

    The car itself is almost completely stipped and once the painted axels get bolted back on the car will be going to a paintshop.

    There are no 3,55:1 gears available for the Rekord rear axle, there are 3,56:1 gears for the Commodore, but they don't fit in a Rekord housing. The 3,27:1 and 3,45:1 Rekord E2 gears should fit, but with an exception, The 3,45:1 gears from a Rekord E 23TD and 22i Caravan don't fit as the diffs are of the same type as the Senator/Monza/Omega diffs. You must take the gears from a five speed 20E Sedan/Caravan or a four or five speed 22i Sedan.

    A 3.55 (a 32/9 gearset would be 3.555555... so 3.55/3.56 are the same) vs a 3.67 (33/9 = 3.666666...) reduces your engine speed to about 4850 rpm from 5000 initial (or gives you approx 72.2 mph instead of 70 if you hold the rpm). That sounds like a lot of work for almost no payback. If you are getting the LSD and it has the 3.55, go for it! Just don't want you to spend a lot of time with no payback!

    Enjoy the project!

    My plan is to make this car good for cruising so that's the main reason I will be putting it in. I originally wanted a 3.44 but since I didn't find one for cheap I will build it with the 3.55/3.56 I have laying around. Atleast it somewhat lowers the rpms

    Are you going to use a complete Commodore rear axle ? Welding spring perches is easy but there is a big difference in width, you must narrow it to have some room for the tires. AFAIK the only LSD that fits plug & play in a Commodore axle housing is the stock optional ZF 006. The LSD for a Rekord axle housing is the smaller ZF 004, same as Ascona/Manta etc. Alternatively a Quaife ATB or some other aftermarket LSD. But the 3,56:1 gears and the larger Commodore diff will not fit in a Rekord axle housing, as I wrote in my earlier post.

    No. I will be using the stock axle. And it will get an lsd conversion kit from racingdiffs. Too much work to get the commodore axle under there.

    And I thought we had some bizarre laws in the U.S. That one sucks.

    Oh yeah. The law in Finland is very rough on car tuning. I originally intented to build this car with a c30ne/se engine but obviously couldn't do it.

    It is actually not so bad, you just have to be creative and use the system to your advantage(and sometimes bend the law a little bit).
