98' S70 GLT Turbo Options?

Post by Alecw81 »

I've yet to actually remove my current stock Low-Pressure Turbo, but it's going to come off soon, curious what flanges will mate up without modification?

Straight flange is the only one that will work. 96-98 models used them.

I'm looking for something a bit more interesting than a 15g or 19t.

Um...more interesting than a 19t? I suppose bent rods are pretty interesting.

You can easily get 15+ psi out of a 15 or 16T; any more than that, you'll need some ECU and exhaust upgrades.

Even though the 2.4T's are built stronger than NA engines, they don't have the increased cooling capacity of the 2.3L engines in the block, so I probably would not run an 18T or 19T on that engine.

That's what propane injection is for.

Anyway, not necessarily looking to run 20psi, but it'd be nice to see if a TD05 Big20G can work. I'm much more familiar with turbos from the DSM world.

Good luck with that, all I can say is find a good used motor for when you snap rods..
