I was thinking, someone should port the Gavril V8's old-style and late intakes from the truck to the Grand Marshal. That way, you can get your underpowered TBI land yacht experience unfettered by modern witchcraft Only problem is, the Grand Marshal's engine file is structured completely differently from the truck's... I would do it myself if I could figure it out!
Interestingly enough, as I found out while working on the facelift Grand Marshal for WBIMP, the “late” pickup intake is actually the same as the standard Grand Marshal one.
