power adds on your 4BT or now anyone who has used 6BT upgrades on a 4BT?
There are countless people who have enhanced the performance of their 4BT. This ranges from balancing the engine, making a custom-cut camshaft, new injectors, different turbos, intercoolers, turning up the fuel, and many others.
These can be found on the 4BT Swaps Forum: http://www.4btswaps.com/forum/index.php
I am happy with the performance of the stock engine, however, I do plan on many upgrades over the upcoming years.
I recently bought gauges (pyrometer, and boost). I'm reworking the dash to look better with all the gauges I have. Anyway, you need to know exhaust-gas-temperatures before you start messing with the fuel; that way you know where you were before you started.
My plans: Install gauges, turn up the fuel, add the 366 governor spring, 6BT harmonic damper, add an intercooler, possibly change the turbo, and then who knows. This will all take it's good old time (a few years).
I just broke my first u-joint, better go fix that first.
