So in the next while I want to start building a volvo rally car, and want to do it with a canadian(I'm in Canada) car with a B23E. Turbo is fun but too futzy I figure...I just want some good 140-150hp I could get out of a B23E. Anyways, who knows which cars had that engine? 81GLT's I think, but I'm not sure what else. Any info appreciated. thanks as always,
Nate Gundy

Canada had the B23E in the '81 - '83 GLs and GLTs. GLEs would have had them too if they didn't have the 6 cylinder in them.
In Canada GLTs were a normally aspirated version of the Turbo which were badged simply as Turbos. In the US the GLTs were turbocharged.
The Canadian B23Es had the 405 head and the K cam and were about 136 hp. A Canadian B21F had a 398 head which they used on the B23Fs in the USA.
I have taken a B21F with a 398 head, put a K-cam in it and bored it out to one overbore size past B23 size, shaved the head a bit and put flat topped kolbin-schmidt (sp ?) pistons in it. It had at least as much power as my current B23E does but it needed high octane gas and was a bit hard on spark plugs. Lotsa pep though ! :)
If you want a 405 head and K cam I've got friends that always salvage them out of the junk yards, get them machined and cleaned up and sell them to Americans. Their prices are pretty reasonable. I can put you in touch with them if you want.

This engine got a few changes over the years, and there are also variations depending on the different markets. This is the story to the best of my knowledge, based on the cars marketed in Scandinavia:
The first B23E was born in 1979, destined for the new GT model (introduced to meet the challenge from the new SAAB 99 Turbo). The 405 head and the H cam gave 140 BHP. The first change came in 1981, when the milder K cam reduced max output to 136 BHP - to meet the stricter emission regulations, but also to move the powerband down RPM-wise. In 1982 and 1983 it remained unchanged, and was used in the some of the GLE and all GLT models. In 1984 it got the A or the V cam, depending on market, and power was down to 129 and 131 BHP. The low friction B230E was introduced in 1985. CR was increased to 10.3:1, and at least in Scandinavia max power output was 129 BHP.
In late 1988 it was all over, from now on it was just the catalyze'd and EFI'd B230F.

Except for the later ones with the 531(?) heads and hotter cam (V, X, or VX I think.. forget which). Let's not forget the B230ET either.

Ah yes, the B230FX. It did certainly have the 531 head, and I think it had either a VX or a VX3 cam. The B230ET completely slipped my mind, thanks. Volvo never put it into a standard 240, but still.

Just curious, did the B230ET use Motronic Fuel Injection? -rather than LH Jetronic? If you look at the pictures of the engine bay in the Haynes 740/760 book, the AMM and a few other components sure look like something I'd expect to see on a VW with Motronic or some "D" variant. It's definately not a US-spec AMM bolted to the top of the air filter box.

Fitz,
I have no personal experience with these engines, but according to this page (http://www.autoelectric.ru/auto/volvo/740/1989/740-89.htm, second engine from the top), it did indeed have the Motronic control unit and power stage.

I nearly bought a US spec '83 240GL that had a B23E w/K-jet and was badged under the hood as meeting US emissions, and a 10.3:1 compression. I wanted it badly but the guy who was selling it knew what he had and it was pricey. He said it was 141 hp. This was in Connecticut in '89, and didn't think the B23E made it to the US.
The best way to get where you want is to find a '79- B21F with 391 head, bore to 2.3L use Mahle alloy pistons, 1" mains and a K cam. I have one in my garage that dyno's at 180 hp after porting the head and raising compression to 10.8:1 and using turbo K-jet injectors along witha GT fi pump.

Oh, I forgot another option, the Volvo Penta Marine engines were both fuel injected and carb, some 16v IL4 cyl 2.3 and 2.5L that were high compression versions of the B23. IIRC the AW 171 was a FI 2.5L 16v version that produced 180hp. The AW 151 was an 8v version with carbs that produced ~140hp.

Thanks for the info. Problem is that as much as I'd like to fully rebuild an engine and overbore it, I just don't think I'll have the money in the forseeable future, considering all the other stuff I'm going to have to buy to make an old 240 a rally car. I wonder where I could find a penta engine though. That could be fun. I am hoping I'll be able to find an 81 or something with a B23 that I could just take the head off of, get it ported and polished with bigger valves and shave it a bit to get compression up. I'd run racing fuel anyways, so the compression could be sick high. If only I had an unlimited budget.....

That '81 244 GL sitting under the car cover has what's left of a B23E in it. I've really stripped it. The block is still in but the head's in the garage. The k-jet parts got tossed.
The previous owner topped it up with water to get it to me, so a frost plug is out. Looking kinda rusty.
If interested, stop by to look at it, or send Andrew(?) over. Let me know ahead as I have to see what engine parts I have remaining.
Car will eventually be scrapped.

Andrew says he could come look at it and take a few digital pictures to send me. He says he is free either sunday afternoon or monday evening. Tell me what works best. My email is nate_gundy at yahoo dot com. Thanks again!

Hey, I'm very interested. I wrote Andrew, and he may well come over this weekend. Do you have an email I could write you to? I'd love to get the engine, as long as the rust isn't beyond saving it. It's just the kind of project I'd like to have this year. I could go little by little, and then I could find practically ANY K-jet B21F or FT and this would basically be direct replacement. Heck, I'd be stripping the car anyways to get seam welded and the like. You got me all excited. Hah. thanks trev.

the 245 I learned to drive on was built in Nov '83, and was badged as an 84 240GL, it had a KJet B23E.

Hmm....I wonder if that was just specific to the Euro/Aussie market. The different markets varied quite a bit in this and that detail. Tis a good point though and I'll keep my eyes open. thanks

In Canada, the 1981,82,83 model year GL and GLT had the B23E engine. The 84's got the B23F with early LH. 1980 was the B21F with K-jet. All B23E had K-Jet without the frequency valve or O2 sensor. They had 10:1 compression and used the K cam in 81, 82, and some had a different cam in 83. I forget which one, but it was used to provide a smoother idle. Horsepower was 137 in 81-82, something less in 83.
Hell of a good engine - Volvo's best in my opinion.

I think they used the A cam in '83.

According to my Chilton's manual:
1982 and 1983 GL and GLT.
81 GLT (again, according to Chilton) only came with the B21FT motor.

What are the differences between a B23E and a B23F?

B23E: 405 head, K cam (81,82) H cam (79,80 Austalia and Europe) 10:1 compression. Kjet.
B23F: 398 head, M cam. LH. 1984.

There are actually 2 types of B23F. two different compression ratios.
But the B23F has LH-Jetronic. The B23E has K-Jet.
You *could* take a hi compression B23F short block and fit a B21F head and injection system, and get really close to a B23E.

Hey. that's a thought indeed. It'd just be nice to have it there all in one to begin with. We'll see. I still have to find something for a good price...as in under $400. I'm hoping to find something with a blown headgasket that someone doesn't want to fix or the like. Anyways, thanks for the help thus far.
