Series 1 fuel pumps on the L67'* support 400 horsepower, but they also outflow the S2 pumps.
If you have good fuel pressure in your supercharged 93, you will be ok. But if you were swapping into a car that originally had an L27 or L36, you would have to swap pumps. Bear in mind that fuel pumps in older cars get week. We see a good number of S1 pumps that fail with age, or get weak. Checking fuel pressure is a MUST, as the fuel pressure regulator for the S2 is 3.5 bar, while the S1 67 runs at 3.0 bar or 2.7 bar depending on the year. In other words, the S2 is much more sensitive to a weak fuel pump.
Struts are like tires and windshield wiper blades. Consumable parts that wear. It'* not common practice to use wrecker parts as replacement, and that is the ONLY viable option. New CCR struts are over $500 if they're still available.
Yes, DEX is known to become acidic over time. And in far fewer than 5 years in most cases. This is why nearly every Gearhead on this Forum will encourage you to lose the DEX at the best opportunity.
