I'm trying to sort out what to do for a dual circuit master setup in my FJ55 project with a 2FE. I've done some searching but with boosted vs manual, 4 drums vs front disc vs discs all around, various clearance issues, etc in different threads, I'm not getting much closer to an answer.
The truck has 60 axles with front discs and rear drums. The intake on the 2FE doesn't leave much room to play with without shifting the engine mounts to make more room.
I can see three possible routes to pursue.
1) A dual circuit manual system. I have one of Mark's adapters to go from 3 bolt to 4. Wouldn't need much space to fit this. Will a manual master work with a disc/drum system? Will a master from a boosted system do the job with no booster or does a manual system demand a different master? I understand that pedal leverage ratio and master cylinder bore may differ between boosted and manual setups...
2) Shift the engine to the passenger side to clear a booster. It looks like the position of the throttle cable on the firewall would limit booster diameter to about 7.5". I'm sure there is room to shift the engine enough, but is there a Toyota booster this narrow? Both my FJ62 and Camry have boosters 8.5-9" in diameter. Suitable non-Toyota booster?
3) Hydroboost. Judging by my F250 this would be fairly narrow. Would a 62 PS pump run hydroboost alright, or would an upgraded pump/system be needed?
Other suggestions?
Thanks for any help.
