Wes , thats probably what i'll do . The question was really to find opinions on whether at the power level i will be running @ 400hp , there is an advantage in using the 500 TB and elbow over the std one ! As i already have the 500 kit i think i'll use it so i can use the bigger intercooler ,all this aids power and ACT's .

I have no knowledge about big capacity jap injectors , can you really get similar power to 8 injector engines at lower boosts ? I will be using a T35 .63 , race turbo ,P8 , BD 14's etc.. Would be interested to hear how other people have got on , especially if you fancy dyno'ing my engine after its built !
