I am purchasing a Greddy sohc turbo kit w/ intercooler. I was wondering since it uses a mistu TD40H-15G. This turbo has an internal wastegate. What turbo would i be able to upgrade the TD40H-15G to a lager turbo w/ internal wastegate so i dont have to purchase another manifold for external wastegate. This is going on a 1.6 sohc motor , so the turbo doesnt have to be large. Im looking for something that is capable of making 15+ lbs efficently (sp?). Not that im going to boost that high off the bat , but i am going to be upgrading the internals as well.
