View Full Version : Ford C4 auto swap KA/SR

I think this might be the best swap for high power applications. Its strong and dose not rob much power. And its a 3 speed so you will not rev like crazy on the highway.
Here are some specs/info on a S15 that has one...
Drag Racing:
- C4 drag prepared automatic transmission by Dominello's
- Full manual shifting
- Hi-stall convertor
- Custom driveshaft by Bosnjak Engineering
- B&M quicksliver shifter
Dyno Testing:
- S13 5 speed manual transmission
- Direct Clutch 5 puck brass button twin plate clutch
- Custom driveshaft by Bosnjak Engineering
Differential: Nismo 2 way mechanical LSD



That might be a stock SR bell housing the adapter is here.... it might work on a KA too if the Autos are similar to the 5 speeds... you can just swap bell hosings...

if you were going to put an automatic in a 240.....thats the way to go.

to make full good use of that, you would need about 500WHP.

yeah.......thats the idea. Though i think a lower 400rwhp car could make pretty good use of it

That setup was put together by Croydon Racing Deveopments (http://www.croydonautosports.com.au/) in Sydney, if people want details you can probably email them (though the workshop is closed for christmas atm). It's also what they use on Devlsh
