D24 N00b..

Hello D24T.com users!
My name is John and I am 19 years old.
I was linked to this site after asking some questions on Turbobricks.com.

So I just purchased my first 240, and I am quite excited to say it is equipped with a factory D24 and M46!
I have been into Volvo's for the past few years, but mostly 850's and x70's.
And a 240 has always been on my wish-list, along with something diesel.
Now I get to have the best of both worlds

So I have heard/read that the D24 is not as resilient as the D24t.
The block is a softer alloy, no piston squirters, weaker rods, yadda yadda.

Is there anyone on here who has experience turbocharging a D24?
Not a D24t!
I saw one video on youtube where someone turbo'd their D24, and it was niice.

Well, if anyone can help me find a solution for breaking 100bhp, I would really be appreciative

Thanks,
John

Hello John and welcome!

The D24 block is supposed to be a softer alloy because of a lower nickle content, though i don't know how much a problem it is for strength, probably more of a cylinder wear issue. The crank and rods are the same, and yes it doesn't have oil squirters but if your not pushing 20lbs of boost drag racing the thing I wouldn't worry about it. When adding a turbo, you will want to add an intercooler and a oil cooler. Try messaging either George (v8volvo) or Kevin (slobodan) on here. They both have lots of engines/used parts and may have an exhaust manifold to spare. Your intake manifold is already great for turbocharing as it has the big snout out front to plumb your tubing into thats comming from the intercooler your going to install! You can probably also find yourself a used stock turbo if your wanting to go that route. Between the turbo, intercooler, and some pump tuning you should be well over 100 reliable hp assuming your engine is in good shape.

The problem I have heard is premature bore wear, but that is what I have heard, and I don't know this by first hand experience.
I was thinking around 10-13 psi would be a safe assumption for future plans.
I have a 13g from my older 850 LPT, so that will do the job for a while

Intercooler and oil cooler is definitely a good idea.
Yea, I noticed how large the "snout" and plenum was, for something n/a.
I might weld up an exhaust manifold, utilizing some of the stock manifold.
depending on whether or not I can find a D24T manifold.
Either way, 80 BHP in 1984 is not going to work for me..
I think it is safe to assume that it doesn't have 80 hp anymore haha.

But it's a pretty nice set up:
1984 quad square front end wagon
D24
M46
Leather interior
O.K. exterior, in need of a respray and new hatch (although the guy I am buying it from is giving me a spare hatch)

It hasn't run in a while and needs:
A new battery
To have the fuel system cleaned
And all fluids exchanged.

Not too shabby for $450

Sorry for the extremely long 2nd post haha.
Thanks,
John

Sounds like a good deal for $450. The bores do tend to wear worse on the NA blocks, but its a combination of the softer alloy and the build up of soot they tend to get around the rings. Without the turbo to push in some air and help clean things up, they get sooted up over time. That is just like rubbing sand paper up and down the cylinder walls constantly. Make sure to run some good oil in it, such as 5w-40 synthetic. Rotella T is always the cheapest around here, Waly-world has it for $19 a gallon.

That is what I have also heard..
I'll turbo it once I get the thing running up to par.
I might yank the motor out and fix it up a bit, but we will see how nicely I can get it running while installed.
Yea, I usually get my oil from walmart.
I could care less if I save money on my oil by buying it at walmart, but apparently that is taboo on Volvospeed

Well thanks Jason, you seem to know your D24's.

Thanks, I'm by no means a huge expert, but I do own the forum, so you would hope I would have something usefull to contribute!

As for wal-mart, ya ya your supporting the massive wal-mart machine but guess what, the oil is cheap! With the way these things like to use it I need to save where I can!
