sorry , took so long to get back to this thread , however as u see i did acheive the 350whp .
326whp as on 91 octane at 20psi and 352whp was on 97octane at 20psi , same map but with a little more timing, could have gotten more , but acheive my goal , so stopped at that pt .

Nicely done. One question though, how much lag did the 20g give you? Kinda curious.

actually , i was quite surprised that lag was not an siisue , especially since the turboxs FMIC is very large . I get full boost 22 psi in 5th and 6th gear at 4000rpm , it starts spooling around 2800 -3000rpm . I can accelerate in 6th gear from about 3500rpm , no need for me to always down shift to lower gear to accelerate . This is why i choose the TD05H housing , even though its 8cm , feels no different from when i had my TMIC , i can testify that the 8cm housing is extremely strong in the top end , at 240mph it still cont to accelerate , its frightening !! The best all round street turbo for a 2 L on pump gas.

these things have helped reduce lag :
1. 3 port prodrive solenoid
2.APS uppipe
3.smaller TD05 turbine vs TD06
4. Heat coated the turbine
5.intercooler pipe diameter not too large
6. cusco divorce type 3" DP
7. perrin 5 ply turbo inlet , less resistance to flow than stocker

i have stock unequal lenghth headers , u guys think there is any benefit in upgrading to aftermarket unequal headers , dont want to loose boxer rumble and concerned that if header pipe diameter is too large , it may reduce exhaust gas velocity .

your opinions please . NB dont really want to do P&P

it will need a retune, but you will see a gain--at the least the time of spool and some torque at virtually any rpm--only after the tune though.
As far as cost-vs-benefit analysis, it is not worth it, but as an upgrade that will prep you for potential future mods, it is perfect.

I have read plus and minus, suppose it depends on what brand/type, and also the tune of course. I have heard most people say that the PnP with highflow crossover is just as good.

I just installed a td05 16G turbo and to me there's litttle to no lag and it pulls alot harder than the tdo4, but over all i'm happy woth the performance i'm gettin out of my wrx, just to give you an example of the performance, even tho the stock wrx would put the Civic Si to shame, but i raced one last night with turbo, FMIC, and exhaust and intake, still got'em at 3 car lengths easy, no B.S.

Did you mean 140mph? Or is that 240km per hour? Either way that's sweet.
