really not much, in fact following exactly what was done by the OP is a good idea. However a true 3" exhaust (no bottleneck like OP) should be mandatory and the option for catless downpipe (race cars or the states where it is legal) would spool faster and make more power

thanks for the feedback. I agree this setup makes a lot of sense for people who are mostly stock or stock-ish. For those who are currently rotated it might not make as much sense unless wanting the TMIC and stealth factor. I dont know of many stock location twinscroll turbos but if youre referring to the JDM twinscroll turbos, the limiting factor imo will continue to be the odd shaped turbine wheel and housing

we'll have the 7670 EFR available in rotated single scroll OR rotated twinscroll, but it can not fit stock location

this setup is not for everyone. If you want to make big power our rotated kits are available in singlescroll (similar to stock location just rotated) OR twinscroll - both with B2 EFR turbos. If the 7163 is too small but you want to stay stock location i will say its not possible to fit the hulking B2 here (must rotate it)

no, those headers almost always crack so we will not support that platform

if you have a fully built subie it can handle the bigger units... but overall I agree the 6758, 7163 and 7670 will probably be the hot items for most enthusiasts on this forum

dont underestimate the 7163... this test doesn't scratch the surface, nor does perrin's. remember Paul's car is doing this thru a cat, stock tmic and 2.5" exhaust restriction (basically a stock car)

For stock location turbos I prefer TMIC... less piping means faster spool better torque and quicker response.

some of the available subie FMIC/charge piping kits have large diameter, long convoluted piping (spaghetti?) which can add a LOT lag and gain nil on the top end... if you are going FMIC keep the pipes as short as is possible otherwise stay TMIC!

there might be a few dyno charts that look similar to these, this isnt bragging rights forum dynos. It is a stock motor with stock everything except for turbo and fuel system... I doubt the guys you are referring to have cats, 2.5" exh bottleneck or stock tmic. I can tell you if any of those bragging rights xtr guys tried this thing they would be there is nothing like the EFR turbos as frustrating as the wait has been I can run any turbo I want on my personal cars and ive got 2 cars down right now waiting on turbos... id rather have be waiting and get the EFR then run anything else currently

not sure yet, but they will have some new stuff on display at SEMA...
