    Building the 242 Turbo Volvo should have....

    So I fixed a heap of issues since my last post and finally have a properly working car. There are a couple small issues like a whistling noise in boost and an exhaust rattle when braking hard/turning right but otherwise it is fully functioning as intended. After all that work, I don't care to...

    Well the last 24 hours have yielded some interesting developments. I swore I had hooked up the check engine light to the EZK but in fact I had not. There were two codes in it, 1-4-3 and 1-4-4. Resetting the ecu and swapping the knock sensor, it ran better for a short time. The 1-4-4 code came...

    They are slower than the TD04s for sure, but something is definitely wrong here. When this engine was in the 760 it wasn't nearly as lazy as it is now. I have owned several 700 series turbo cars and none of them have been this lazy. It acts like a giant boost leak that suddenly seals. As far...

    Building the 242 Turbo Volvo should have....

    I have been driving the car for the past few days, I'm happy to report the steering and suspension is now dialed. One quirk about this car that I have been ignoring until now is how lazy the turbo spools. It will not make any real boost until about 3500 rpm. Being this car has a stock Garrett...

    A few different reasons. For one, the VW radiator temp switch does not work very well. Even with the lower temp version the fan would not kick on until 210-215 degrees at the cylinder head. I could now wire in the ecu fan control to fix this though. The second reason was the electrical load. I...

    Things have happened, the car is once again back on the road and the steering wheel shake is gone. The steering rack went right back in no problem. The power assist is now way better than it ever has been, all of the "harshness" previously felt in the steering wheel is now gone. I'm very...

    Last weekend I reinstalled the octopus and swapped out the rear proportioning valves. It firmed up the brake pedal quite a bit. Time will tell if this is the fix for the chronically leaky octopus. Really don't want to have to clean up that brake fluid mess again. Dropped off the steering rack...

    Alright, quick update: I found a potential cause of my premature octopus failure, one of my rear prop valves had also failed causing the switch inside the octopus to repeatedly move under normal braking conditions. This can wear the orings out prematurely according the seller I got my octopus...

    Another hobby of mine happens to be repairing vintage electronics. Going through one of these radios involves cleaning all of the controls, reflowing cracked solder joints, testing and replacing open electrolytic capacitors. The tape decks usually require a good deep cleaning and lubrication...

    So its now late 2024. I never made Carlisle 2022, 2023 or 2024. I've neglected to update this thread but progress on the car has continued. Slowly. Parts proved difficult to find, then I got really burnt out on the whole thing and didn't touch it for almost a year. It hasn't been easy, but I...

    Murphy's Law 242: Caster woes and the unsolvable steering wheel shimmy

    Alright, I've had some time to check out a few of these different potential causes and some new ones. The car is now fixed. Here's what I've found: I ran the car on jack stands with the suspension loaded up to 100 mph, absolutely no shake. Removing the power steering belt and driving the...

    Murphy's Law 242: Caster woes and the unsolvable steering wheel shimmy

    Appreciate the replies from everyone, I have a few more things to check now. The shimmy only gets worse the faster you go. I can't find a certain speed where it diminishes. Over 80 I can't see anything out of my rear view mirror and it feels like the car is going to shake itself to pieces. As...

    Murphy's Law 242: Caster woes and the unsolvable steering wheel shimmy

    Hi all, I don't post all that often but I have encountered an issue with my 83 242 that is absolutely driving me nuts. Those active on the Discord server are familiar with my ongoing battle. The car has a very strong steering wheel shake/shimmy at 60+ mph that I just can't seem to solve. The...

    Hey Y'all, Long time lurker here. Some of you know me from the Discord server as 242B23FT. Just wanted to share my adventure of taking a rough but rust free '83 242 DL and turning it into the 242 turbo that I believe Volvo should have built. If you don't care much for back stories, feel free...

    '84 760 Turbo miss at idle

    Ive been daily driving my '84 760 turbo for about a month now and haven't had any issues other than an erratic miss at idle. Some times its bad enough to where it shakes the whole car. Other times its smooth except for a little blip every few seconds. Cold or hot it doesnt make a difference. Its...

    Just bought an '84 760 Turbo

    Hi everyone, I just recently bought my first turbo brick while looking for a commuter car. My brother talked me into looking at turbo 740s and 240s. I found an ad on Denver Craigslist for an '84 760 with a manual trans. The car ended up being a factory 760 turbo with a 4 speed + OD. It has IPD...
