my next mod will be an ebc,
but went to the drags on Wednesday and pulled a 13.8, this is with a pretty mild launch (I know how much they cost to fix) and only ran the boost at 17psi,
I'm quite happy with that, seeing as this is more of a track bandit than a straight line warrior.

everything turbo wise seems to be ok, no dramas at all. got a track day coming up in June, then we'll see how it really performs

been doing even further reading

a lot of the silvia people are choosing between the gt28rs (disco potato) in either a 0.62 or 0.82 exhaust and the gt2871r in either  46, 52, 56 trims with either 0.64 or 0.82 exhaust.

now the gt28rs for the silvia boys has a max power of about 220-230kw with cams on around 17-19psi, while the gt2871r has about 240-250kw power with cams, but with 20-22psi. apparently the gt2871r really loves the bigger boost 1.4bar+

i really think ur exhaust system and dump is letting you down. im estimating we will lose an extra 10% from our drivetrain, so with the gt2871r you should get about 230kw with all the support mods (which you alrady have)

ill write a bit more later from my research :)
