Well i have been thinking about so many different turbos lately for my needs. But for some reason the Td06 comes to mind all the time, since i have seen 2 r33's in the flesh that run TD06-20G turbos and they go respectably well i beleive this has convinced me that this is the turbo choice for me. Although i will go The 25G not 20G, MY engine has decided that it only wants to hold 30psi in number 5 cyl and there its need to be fixed. Was considering the Rb30/25 conversion but its not something i want to do just yet, So forged Rb25 is what i am going to continue on with. I will not be bolting the Td06 onto the stock exhaust manifold, it will be either a trust or hpi one. Basically along with cams, adj cam gears, power fc and the needed support items my power target is between 350-400hp at rear wheels.
My questions are. Will the td06-25g be efficient around the 1-1.5 Bar mark, have no intention of going higher? This will continue to be my everyday drive car so this turbo shouldnt be any hassle driving to n from work? Would people suggest any different similar sized turbos to maybe consider? Also if i am looking at a new TD06, how am i to measure the exhaust housing size to know whether its adequate or not? Any help is much apeciated aswell as any further info u think i should know
