The aluminum coolant passages on the B280 are in great shape, which isn’t exactly a surprise with such a low-mileage motor. Once I replaced the split water pump I reassembled it with a new thermostat and had it ready to go and was feeling good. As I was test fitting the radiator and hoses recently …

Snabb intake upgrade
Last time the 850R was at the shop they noted that the factory intake pipe from MAF to turbo was on its last legs and needed replacing soon. Which sounded to me like a great excuse for an upgrade. The stock pipe is an accordion type plastic hose and is a slightly smaller diameter than …
AW71 accumulator mod
Though the AW71 should be able to handle all the power the B280F makes and more as is I decided to shim the accumulators while it was out of the car and relatively dry. More because if I’m going to do it now is the time rather than feeling a need to do it. But …
B280 oil and water
I have not given up on the Bertone project. Though it is admittedly hard to tell due to the lack of progress. Today I used a vacation day to get some work done. The replacement b280F has been sitting for the better part of a decade so I am replacing some of the more common …
do88 Intercooler
I have been thinking about upgrading the stock intercooler on the 242 for years. I’m not sure that it is the limiting factor in how much power the car makes, but I think it is close to being a problem if it isn’t the weakest link. Testing others have done show the stock intercooler becomes …
Heat shields
The R did not have exhaust manifold heat shields when I bought it. It has the upgraded late model exhaust manifold and an aftermarket downpipe so the stock heat shields do not fit. Finding the right heat shields for the new manifold on the old car turned out to be harder than I thought it …
Power Steering: factory jury-rigged
There was a clamp around the power steering reservoir of my old M130 that I sort of assumed was some sort of odd side of the road repair that had never been fixed properly or else was just a strange storage space for a spare clamp for an intake hose or something. Couldn’t quite figure …
M130 Prep
The “new” M130 is finally turned around in the garage so I can access the front of the engine and the injection pump. Supposedly this engine was running well but there was a fueling problem of some sort. Since my old engine was running well except the oil consumption issue I plan to swap my …
Automatic compromise
I have decided to simplify the B280 install by sticking with an automatic for now. Since I am intending to use the stock fuel injection and ignition for a 760 I will need a crank position sensor. Which would involve machining the flywheel and bellhousing for a manual since the even fire Volvo v6 never …
Yearly cleaning
The wagon has been difficult to start after sitting for more than a few days and I’ve been trying to ignore it until warmer weather. Last time I drove it was stumbling badly when cold, so I figured it was time to move it into the garage and investigate. And since it will be inside …
