I have subaru b4 legacy 1999 with twin turbo from Japan and I would like to increase the torque and speed. Where do I start.


hi i would invest in an electronic boost controller, they remove the dead spot in the revs before the big turbo winds in, they are worth a few hundred dollars but are well worth the money. You also have the option of turning up the boost safely a few psi with these but you will love the difference without the dead spot it will seem like a new car to drive. If you do that and want more still i would get a turbo upgrade, ecu upgrade, fuel pump upgrade etc do all that you can before going with the expensive motor rebuild

Just wondering if it possible to make the twin turbos on a 2002 legacy gt work at the same time like a single turbo instead of converting it to single turbo


The turbos are two different types.One is designed to start a bit lower in the revs and the other to come in when the revs are higher.Its called compounding boost.It can be changed but to put it on a sinlgle turbo would cost a fair bit.If you hot up the ones you have by recalibrating them and exhaust,you do get VERY big gains.The car is more driveable and you can get big boosts in power if the tuner knows what he is doing.Some really big horsepower units come from triple compounding turbos and the torque levels are extremely high.Hope this helps

No boost


Check all the rubber hoses to and from the inner cooler for cracks, make sure all the clamps are tight.
