Back when I was collecting parts to take my S15 to the next level, alot of thought went into the turbo choice. My S15 was 'full boost spec' which is a setup that sees the stock turbo running about 16psi. With supporting mods, is good for around 200rkw. (Mine dyno'd @ 198) Line 8 (White) is like what my S15 was, my new turbo is Line 1 (Yellow).
Anyway, I wanted a turbo that had no more lag than what I had, but was capable of good power. Looking at this graph, you can see why I chose the Tomei M8270.
Going any bigger than this results in more lag.
Will be interesting to see how the beams head compares, as it should help spool and topend, over an sr20.
I'll get the dyno overlaid over the NA setup, and also my old S14 from years ago that was also 'full boost spec' and was 195rwkw.
It's possibly going to be overkill having this much power in an ae86. I thought my silvias were quick enough, well until they went to the track. The ae would be at least 200kg lighter than a silvia (at a guess)
But, a stock 3sge bottom end is sketchy at 200kw, and seeing as I had the turbo sitting around, might as well rebuild motor and go straight to 300kw. Also, I knew that if I spend the money and set it up for 200kw, I will end up wanting more; so might as well just do it straight away.
This pic really makes me want to go white...
