Just noticed this had been unanswered so will give it a go.
First thing first with no Honda engine at the end of 1983, Williams will need something to partner up for in 1985 - 1987. Lets say they stick with the Ford Cosworth till 1985. I wonder if Renault do not give Lotus their turbo and infact start the Partnership in 1985. So Tyrrell and possibly Lotus lose out on Renault turbos?
For Spirit, I wonder if the extra income for the team but lack of established structure means that the engine takes longer to be a race winner or at all. If no success, a Honda exit before 1989? Nakajima maybe makes F1 debut earlier as a result (1985 or 1986perhaps). Spirit probably survive till the end of the eighties, but the knock on effect to Lotus and Tyrrell if Williams get the Renault Turbo is maybe Lotus fold earlier (say 1987) due to no competitive work engine deal and Tyrrell having to take worse engines when Turbos became mandoratory. I imagine JPS, Camel, Renault and Honda gave Lotus a help with finances and the successes meant they could survive after Chapman's death. Renault still pull out after 1986 so Williams if gained the turbos have a non turbo for 1987, who knows if they return in 1989. McLaren keep Porsche engines for longer as lack of power in 87 no longer an issue, perhaps Active suspension is not developed at all. Ferrari, Benetton, McLaren become main contenders in 87 while Williams perform strongly in 85 and 86.
On the driver front, I imagine no Mansell world champion as his career probably ends by being dropped by Lotus in 1984, no third world championship for Piquet who perhaps joins Benetton in 1986 instead of Fabi due to BMW link or stays at Brabham for 86 (does he suffer De Angelis accident?). No lap record for Rosberg in 1985 but is kept on at Williams till 1986, likewise Laffite probably stays and does not have his Brands Hatch crash and retires around 1988. If Senna chooses a Williams Renault after 84 perhaps no Senna to Lotus but De Angelis does not go to Brabham in 1986 as a result and does not die in testing crash. Warwick get to drive for Lotus, so no Dumfries in F1. Johansson does not leave McLaren, perhaps wins a race in 87 or 88. Alboreto stays at Ferrari longer and likewise does not see such a drop in his final years. Berger ends up at McLaren or Williams instead of Ferrari who perhaps end up with Senna and Alboreto. McLaren keep Prost and Johansson, Benetton Piquet and Boutsen, Williams Berger and Patrese maybe? Does Brabham stay stronger and not get sold be Bernie and maybe takes part in 1988? Therefore no Gordon Murray to McLaren as designer, Modena keeps the seat and does not go to Eurobrun, perhaps is partnered by Brundle.
