Triton Turbo
Posted: Mon Jun 11, 2012 10:23 pm
Hey guys,
Been lurking around these forums for a year or so, only just signed up as a member. I don't have a Sigma or a Galant, but I do have a passion for Mitsubishi's. I own a 1988 2WD Triton at the moment, with the 2.6l 4G54. I am collecting some parts to throw a turbo on it. I already have turbo and exhaust manifold sorted, I've spent much time researching blow thru setups, and for a budget setup, this is the way I'm wanting to go. It's my first ever turbo conversion, so mainly doing it for fun. I will be upgrading the brakes before any real work is done.
I'm just after some answers for some questions I don't believe have been answered in these or other forums. I already have a Weber 34 ADM on and tuned, been running flawlessly for the last 3 years. Now I know about boost referencing carbs on blow through setups, what if I were to take the float bowl vent, and tap and thread a fitting to it, and connect it to the boost side of the intake. I cannot see how this wouldn't work? Would it not be the same as enclosing the entire carb in a pressure box? The float bowl would see the same pressure as above the throttle plate.
Now the turbo I've got is a TD04-13G. Some may say it's too small, but I believe it will be sufficient for the low boost levels I'll be running on the blow through setup. I'm looking to run a max of probably 8psi. It is an oil/water cooled turbo. Now another thing I'm pondering on is where to take the coolant from to feed the turbo? The coolant lines on the turbo are only small, I was thinking of routing the coolant from the bypass line off the water pump through the turbo then back out and let it continue on its way back along the driver side of the block around the back to the inlet manifold/heater(??) as it does now. Would there be enough coolant flow through the bypass hose to cool the turbo sufficiently? It would be convenient to take the coolant from here as it is on the exhaust side already.
I know the turbo has a restrictor in its oil inlet, do I take the oil feed straight from the oil pump? Is there an upgraded oil pump I should consider?
Other than that I'm pretty confident everything else will work.
Cheers guys
Lee
