Seems like these new HTA turbos are pretty exciting. Just after opinions on an HTA3076 on a twin cam RB30. In the past with the old garretts, the 3076 did not seem to have enough top end and tended to be out of puff high in the rev range. However these new HTAs seem to flow a bit more. Now in this situation I would be after great response but without running out of puff up top. So just deciding between the HTA3076 or HTA3582 and wondering how people think the HTA3076 would behave. Specs are as follows
RB25 neo head stock with tomei 260 cams (will install some better valve springs)
Running E85 - 1000cc injectors and 1000hp fuel pump
plazmaman plenum and throttle body
6 boost manifold, turbosmart pro gate
intercooler, exhaust etc etc
RB30 bottom end stock for now
I would be after anywhere from 350 to 400rwkw with good response for a street car. I am thinking if I keep the relatively low duration tomei 260 cams with VCT, E85 and the 3 litre bottom end, these three factors should really give me quite a responsive combo. I am thinking it would be super super responsive with an HTA3076 but am just a bit concerned about the top end. I would think the setup would still be relatively responsive even with the HTA3582.
So which would you go for in a fun street car?
