The Volvo P1800 B20 Build - Part 3

Welcome back! This time we get as far as a pretty much finished long block! The bottom end buttoned up, the freshly ported cylinder head goes on - and as a treat, there's a mighty fine burnout from above the polar circle!
This series shows how to renovate and build a Volvo B20 - or a similar engine of your choice!

Får så härliga flashbacks från mitten/slutet av -80 talet när jag ser dina videos. Grymt jobb du gör👍. Längtar till nästa video kommer.

[@ClassicCarRacingRestoration]

Kul att höra Peter! Var du aktiv Volvoskruvare då?

[@uncle_moose]

@@ClassicCarRacingRestoration jo hade ju en -71:a hundförtti själv som jag höll rullande. Sen åkte jag kartläsare åt en kompis som körde nationell C på 80 talet, han hade en vettskrämd 142:a från -72. Den skruvade vi i tillsammans. Blev några 240 efter det sen.

Great education! Can’t wait to the next Billy. Hope to see some B30 content in the future

[@ClassicCarRacingRestoration]

Thanks Ironhead!! Yeah, I'd really love to build a tripple Weber B30 at some stage!

[@hpieres]

Well done! Perfectly explained and filmed!

[@g-sson67]

Håjj härligt med ett nytt intressant klipp 👍👍👍

[@snorreskistad7780]

Nok en flott episode, beste måten å starte helga på :)

[@ClassicCarRacingRestoration]

Ha ha! Tack som tusan Snorre! Hoppas det blev en fin stund!

[@jorgenkarlsson9725]

Tackar ! gillar verkligen dina filmer, raka puckar o inget krångel i onödan.

[@ClassicCarRacingRestoration]

Tack för det Jörgen! Det är också en målsättning - det ska vara bra innehåll och så lite dötid som möjligt!

[@1814Custom]

Yay..new video..where is my beer?

[@ClassicCarRacingRestoration]

In your right or left hand, hopefully?...

[@TheUltimate65]

Im se you have feet the disturutor then, i have see orther engines rebuld they use a tool on a drill fore test the oil presure before the start...i think about the oil came upp the valvelifts too, too be shore of lube from bottom to the top of the engine...😃

[@ClassicCarRacingRestoration]

Hello! Yup, I do that on Chevrolet engines for instance. Here, with the assembly lube, there is really no need to prime the oil system - a properly set up Volvo will start at an instance, and will get oil pressure in a matter of seconds. And like I said, the assembly lube takes care of the first vital seconds.

Nice, thanks for sharing

[@Avtovaz21057]

good information there! can we see the rally car please?! thanks

[@ClassicCarRacingRestoration]

Thanks a bunch! There are a couple of videos with it on my channel, here’s one: kzbin.info/www/bejne/hZm2qYGDhcZ3ptE

[@cartube7505]

Many thanks for all your interesting and inspiring videos! I really like your custom built engine stand with full access to especially the rear part of the engine. It is certainly a very good idea. I have actually started to build a similar one to be used for B18 and B20 engines. Can you share some of your thoughts and experience about this construction? What thickness of the metal did you use? Also, I look forward to see episode 5!

[@ClassicCarRacingRestoration]

Thank you! Well, actually, there wasn't much thought that went in to this.. I made it some 30 years ago (!) when I was 17-18 years old. It is cut out of a five millimeter thick plate, which bolts to the engine mount holes on the block. Then there is a three millimiter thick angle piece, which bolts to the holes for the starter motor. Thats it!

[@cartube7505]

@@ClassicCarRacingRestoration Thank you for your answer. Very interesting! I thought the metal was thicker. I guess that there will be quite high tensions in the bolts, especially if the cylinder head is mounted. But as we can see in the film, you even torque down the flywheel bolts with the cylinder head already mounted. I will use bolts with steel quality 12.9 and I hope this will do good without any damaged threads in the engine block. On the other hand, the engine mount on each side must be designed to hold at least half of the engine weight (maybe more). On top of this we also have the starter motor bolts that carries much of the force that prevents the engine from turning to the right.

Bästa kanalen! Mvh Figge❤

[@ClassicCarRacingRestoration]

Tack Figge! Jag är alltid lika nervös varje gång jag ska lägga ut nytt material - känns så viktigt att det blir bra!

[@matskarlsson5471]

Har satt ihop några motorer och vi har samma tänk när de gäller renlighet och lugn och nogranhet De jag funderar är varför inte frostpluggarna är bytta ? (Kanske inget problem på Volvo) De byter man alltid på "Raggarmotorerna" 😄 Sedan lärde jag mig när jag gick fordon att man skall sprida kolvringsgapen som du säger men inte ha öppningen på "Trycksidan" MVH Mats

[@ClassicCarRacingRestoration]

Hej Mats, och ursäkta sent svar! Detta block var redan renoverat en gång tidigare, och jag bedömde att pluggarna såg bra ut - men visst kan det vara ett problem. Jag har tex en gång köpt rallybil med motor byggd på firma - allt var nytt - och där lossnade frostplugg bak på toppen, in mot torpedväggen, pga att den var felaktigt fastknackad. Jag har också varit med om att de rostat upp, men det har varit på amerikanska motorer. Och jag håller med dig både när det gäller lugnet och kolvringsgapet! Kan man enkelt påverka slutresultatet, då kan man lika gärna gör det!

[@Flat8G]

Coolt som fan! 😎

[@Blood_Eagel]

Nice👍🏻

[@vinkel8364]

Grymt. Blir så sugen på skruva B20 nu. Heje

[@ClassicCarRacingRestoration]

Ha ha! Det är ju fröjdefullt det - så min rekommendation: sätt igång bara!

[@iansmith6728]

Have you or others used the roller camshafts from AGAP?

[@ClassicCarRacingRestoration]

Hey Ian! I myself have not - yet... It's a rather pricey combo, but of course very alluring! For my part, I have spent quite a lot of time trying to develop roller rockers for the B18-20, but as everything in life, its moving slowly...

[@iansmith6728]

@@ClassicCarRacingRestoration YellaTerra have them available. They have been developed and tested in racing applications. The main test bed is the 122 that runs in the Targa Tasmania each year.
