I have some spare 9 series ic piping if you need it
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Thanks to everyone for the good suggestions. What I've learn so far is that there are several routes to IC, ranging from salvage from 700 series wrecks to OEM TIC kits to modern aftermarket components, but no one path stands out as the easiest or cheapest. My inclination is to stick with salvaged parts and maybe spring for the 240-specific cold side elbow.
Still unclear about the long-term consequences of upping the boost and what additional mods are essential if I put in IC.

The intake isn't terribly restrictive. The exhaust/wastegate housing/intercooler sure is, as is the cylinder head. Everyone wants to change the intake, the B21F/ N/A k-jet intake does flow better, but in terms of more power, it's kinda like breathing through a drinking straw to get everything through the stock head/exhaust & exhaust manifold /wastegate housing/intercooler even if you change the intake..
The direct drop in D088 intercooler looks decent as well, heard good things\, or NPR with custom tabs to drop it in the Volvo without hacking anything up or drastically re-routing anything. Nothing bad can come of more efficient charge air cooling. No compromise win, all metal instead of likely leaky/fragile plastic end tanks isn't bad either. The way the stock IC fits and it's size/packaging is great, just could be more efficient. I'd intercool it with all the stock stuff and drop it in no fuss for now? Maybe buy the drop in DO88 intercooler later? A 3-row radiator and tropical fan clutch is nice for cooling longevity.
84.5 they put a stiffer pressure plate in a few of them with the flat flywheel still. The transmission won't last much longer and everything gets expensive and often compromised or on the ragged edge somewhere to have a balanced well rounded out car beyond ~200-250hp. YMMV.
On a 240T, once you determine the engine is healthy and FI is healthy, you can break the whole drivetrain without a lot of compromise or modification...
Add intercooler to reduce intake air temps. Use one big enough to get close to ambient with big boost with little restriction.....
At stock boost this is safer in that chances of ping or detonation are reduced.
More boost is more POWER.... Provided fuel is provided. It can be turned up from stock to be more amusing without hurting it. Do this.
Depends on the current condition of your clutch. Just putting an intercooler on and upping the boost from 8 to 12-14 psi (on a stock turbo) isn't going to hurt anything as long as you have enough fuel to run those boost levels. At those boost levels is about all the stock clutch can handle so they often start slipping at those levels during full boost. If it does slip, turn it back down until you can upgrade the clutch.Thanks, I'm pretty clear on the concept of boost and the physics of IC.
What I'm not clear on are the consequences of upping boost on other drivetrain components---- would a modest increase in power (say, 30 hp) really pu so much more wear on clutch, pressure plate and flywheel, as nedc and Kjets On a Plane suggest)? Or is this become more of a concern when you go beyond 200 hp?

If you've got the budget for a do88, go for it! As Kjets mentioned it is a better-flowing, more efficient unit.
Also, do88 makes two different intercoolers for 240s, one is the Group A replica and the other is a drop-in replacement.

IMO if you are just adding an intercooler to an otherwise stock B21FT and turning up the boost a little, the do88 unit is a bit overkill and I'd just drop in a <$100 used stock intercooler and use the savings to spend on suspension items.

Ultimately up to you...
Common prices for stuff you bought:I paid him $470 including shipping, which seems steep but made sense to me considering the effort needed to source all the parts. Some of the brackets may be missing judging by the pictures... I guess I'll sort that out when it arrives.
