its been done in Japan, similar to the skyline setup

im running mine in parallel.. until i put the changeover valve back in anyway..
compared tio sewuential it sucks. no boost till where the changeover would usually occur and no benefit in top end.
that is unless you go proper parallel using matched turbos it could be a weapon.


also... there is a B4 in adelaide thats just had a 2.5 put in. i ported the ecv and turbos on it a week or so ago. goes for tuning this week i think.

you dont understand...

2 tdo4s are laggy on a 2.5 and you want to put 2 sti turbos almost twice the size on.... youll never hit full boost!

try a 2.5 with a TF035 primary and TD04 secondary.

yeah, i dont know to much about the whole turbo sizing etc but in comparsion to standard wrx turbos and vf33s what the diff etc .. i spoke to my tuner /mecanic today and they said standard wrx ones more then likely ....

why yo give me that sight ? hmmmm

yeah not much luck ....

awesome thanxs .. hmmmm so what would work best with best drvierbilty and power ..  ?

Billsy, I thought he was trying to avoid sequential, hence twin VF33's may be interesting.

ah yeah i forgot that bit, my bad.

two 33's will still run out of puff near redline, and i imagine it would be a peaky power curve as the A/R of the housings is rather large. but id be fun
lag lag. SMACK on boost.
would also need an external wastegate
