Bought this 240 from midnightsaint a few weeks ago.
It's a 91, he swapped most of the turbo components out of an 87 700. It got injectors from an 04 xc90 t5. And stock factory exhaust with a downpipe welded on. Overall, drove well, and being new to the 240 world I kinda fell in love with the car.
It has c4 salad shooters, but not staggered front and rear, I measured and all four wheels are 9.5" wide. So I'm somewhat interested to know what corvette they came from...
It ran just OK when I got it, but I attributed a lot of that to the 12b. Got to looking around and found a 007 MAF plugged in, presumably from the 87, being lh2.2. Swapped it with a 016 MAF I had sitting around and made a noticeable improvement.
However, after getting the right MAF in, she didn't want any boost over 4psi. Thought I might get a difference from getting my chipped 937 lh box and my chipped EZK box plugged in. Got a little improvement but not much. Did some research, and figured that the injectors were run at roughly 55-60psi fuel pressure on the xc90, so I threw my 4bar FPR in, and voila, she runs not just ok anymore, but GREAT. Throttle response in this car is massively better than my 745t.
So I got my wideband swapped over, and had a local shop put a 3" exhaust on it from the turbo back.
I'm very happy with her so far. Had to sort out an issue with the coolant temp gauge being rather erratic but that's taken care of. Had an issue with the radio fuse blowing, but soldered and heat-shrunk some connections that had wirenuts holding them together and haven't had it blow since.
I still need to sort out the tire rub. I think new shocks and upgrading the sways will take care of it for the most part. Some tires with a lower aspect ratio might do the trick as well.
The only thing I'm not sure about here is this
It's defnitely not causing oil to build up in the turbo from not draining, and not leaking. Just doesn't really seem ideal. What does TB think?
