You will need an oil supply line adaptor- your 90 doesnt have one, and the HX most likely needs one, if it wasnt left on there.
I did an HX35 install on a nonIC truck using the stock cross over. Knowing now what I didnt know then, I'd not do it that way again. I cut 1/2" or so off the end of the stock crossover, then bought a piece of 1-1/4" (I think) silicone turbo hose, and with some liberal use of PB Blaster, I got the tubing over the compressor oulet. I left the OEM hose on the crossover, and layered the new hose on top of it. Clamp it all together, and it works.
If you want an improvement, get a hi-rise intake horn from a FL70, et al, and run an elbow from a IC outlet, and connect it with some pipe and silicone hoses. Better air flow, and you dont run the risk of ripping the silicone hose when putting it over the turbo outlet.
