Transmission swap
I've been doing a little research and decided that my next FE modification will be a transmission swap. But not to a manual transmission.
I'm going to pull the A44DE Aisin transmission out and put in an A350E Aisin 5-speed automatic. Surprisingly, aside from a tail shaft, it bolts right up! This is also giving me an opportunity to build a custom transmission controller and have a REALLY good FE focused transmission shift scheme. I plan on having two schemes. Normal(FE oriented, WOT only takes you to peak torque) and Power (more like your normal automatic transmission shift patterns except WOT will actually take the engine to 100 or so rpm before fuel cut).
Old Gears
1st - 2.45
2nd - 1.45
3rd - 1.00
4th - 0.73
70mph - 3017rpm
40mph - 1724rpm
New Gears
1st - 2.804
2nd - 1.978
3rd - 1.531
4th - 1.000
5th - 0.705
70mph - 2914rpm
40mph - 1665rpm
I get a wider set of gear ratios. Taller first gear and a better overdrive ratio which only drops my rpms by about 100 on the freeway but the 5 gears gives me more wiggle room. This is getting done before the turbo gets slapped on.
I'd wanted to sell the car but I won't get much of anything for it so I might as well just modify it to hell and back. This is obviously a longer term project. Much like the turbo project. Probably going to get installed after winter when I don't need the car full time anymore.
