I still drive one, a dark blue 940 turbo, its my first car, lucky me honestly. Most people in my region (somewhere in SEA) drive MPVs and SUVs. Though where i'm at, parts are a nightmare to find if its not engine/drivetrain parts.

1:07 Hey, m46od! 1:15 The "b" family could refer to every engine they made since 1944 (B4B) to the 2010's (B63XX engines). Soltierally every gas engine they ever made. The b19, b21, b23, b200 and b230 were all very similar to one another, and i guess you could call them the "redblock" family, or just Volvo SOHC 8v family. Then there was also the 4valve b204 & b234, tho these werejust b200 and b230 engines with another head. 2:13 there were dohc versions! 2:46 This is an issue with all old engines. Ignition parts, rotors & caps wears out. 3:10 B230s can safely do 200-250hp, if set up right. At 300hp you're pushing it. The turbo var. of these engines only did 170-180hp or so from factory! 3:57 Got a 1987 740 gle (early model, so 1986 body) and wires are holding up good. Might depend on where you live, of course. Not an issue with the engine itself tho. 4:44 Depends on which year of b230f, the ones with lh2.2 had a sensor in the distributor instead. 4.54 Another common issue with the b230E is the car could be blowing a 25A fuse (no. 12 or 13, dont remember),in that case your fuel relay could be defective (happend to me and i had to tow my car) It is a green relay sitting behind the fuses in the same plastic box. 6:28 Woah! That there is a late 144 (1972?). Which means its probably rocking a b20! wrong clip:( Still sounds great

[@OscZip]

volvo power babyyyy them sound clips were 🔥🔥

[@marcinjedrol]

Thank you!

[@nirracca]

Great video! c: I know exacly where that first sound clip was recorded, I got so suprised!

[@marcinjedrol]

Thanks! Also wow! such a small world!

[@Arraxis]

Do NOT went your PCV box to atmosphere. The Bosch LH2.4 ECU in these cars can seriously freak out when detects unaccounted for air volume. Other than that it's a great vid! 👍

[@marcinjedrol]

Thanks for the pointer! I had it vented out since it was twin carb :)

The picture of 531 head you displayed is the exact head i just bought off ebay. Let me tell you... that guy screwed me. Its off a boat engine so the #3 exhaust port is eaten up with corrosion and the #4 exhaust port which was described as "excellent" has been repaired in a very crude manner with a steel section of pipe shoved in it and weld globbed around it. I disassembled it to find it full of mud and debris. Its ruined. I basically did the guy a favor by doing a complete disassembly so that it can be machined by whatever brave son wants to take that on. Working on trying to return it for a refund. As you might guess the guy but is not a very good communicator. Anyone here want to buy it?

[@marcinjedrol]

Oh what a small world. Anyway I am sorry man. I’ve had luck with 531 since my friend had one complete with the carbs and it was basically plug and play setup. Is there any way you can save it?

[@davidsny1190]

@@marcinjedrol I have the capability to machine it but I would have to cut up port #4 something major to get that steel insert out and building all that back up with weld would be absolutely insane

[@marcinjedrol]

@@davidsny1190I had to go back to see the head. 3:48 Hot dayum, now you say it - yea. You can see the corrosion in the ports. Not sure if some heavy porting could help at this point, if you say only way would be some sort of sleeving

[@davidsny1190]

@@marcinjedrol yeah that's the issue. It's been sleeved already by someone else and it's a horrible mess.

[@marcinjedrol]

@@davidsny1190that sounds like a huge machining task. At this point it would be fully custom head if you fixed it

[@Bellcountyspeed]

I’m jamming 30psi+ into a n/a b23 flavored RedBlock. Supposed to have like 400k miles on the long block as well

[@danjones2913]

That’s a lot of boost on a high compression set up.

[@marcinjedrol]

B23s are even tougher. And 400k miles for these motors are literally nothing 😂 What turbo you packing?

[@hiushiname5495]

Dzięki 🥰🥰

[@Numer1Polak]

AAAHHH yesss the good ole ford Pinto block ..... I mean red block. I love how manufacturers compete with each other but share a ton of stuff. The US ford 2.3T guys have figured out you can run the 90's volvo doch head on them since they are just a modified red block which is also just a modified ford 2.3, so everything lines up. Then we come full circle to ford buying volvo and using their platforms to build their new cars, and sometimes using their engines.

[@marcinjedrol]

Ah yes, the Ford Pinto. And it’s reverse flame livery 😂

[@Numer1Polak]

The car sucked lol. but that the name given to the engine block. Volvo red block .... Ford Fire(pinto) block @@marcinjedrol

[@Fulcrum205]

It doesnt just bolt on. The bore centers and most of the head bolt locations are close enough. Water and oil passages are sorta close. It takes some pretty hefty modifications to the block and head

[@benjaminnurmentaus4232]

What is your opinion on B234 or B204 16 valve heads? They seem to give quite alot more power to the redblock we all know and love

[@marcinjedrol]

It’s a good addition to the motor in my opinion. Especially when you wanna go turbo, it allows the engine to breathe better

[@pontushaggstrom6261]

Nice for power, not as good for reliability

[@benjaminnurmentaus4232]

@@pontushaggstrom6261 what do you mean for reliability? If it gives 30-40 hp more and if you maintain it better and use higher quality oil it won't be a problem. Just better. just a timing chain snap will lead to problems.
