TMIC STI Efective Limits...
Hi Everyone,
I have a forrester sti 04/54 2.5 with a v41 turbo it has had the following mods done to it
3 inch custom exhaust
de- cat
HKS mushroom filter
AVR boost controller
re- map to 1.3 bar =340 BHP approx
HKS iridium plugs
Walbro 255 ltr fuel pump
My question is how much further could you safely boost without any further mods other than a bigger turbo or will I need to upgrade from 440 injectors and bigger intercooler (front or top mount?) .
I am looking for a reliable 380-400 bhp and need to know a realistic budget.
Does anyone recommend anyone for the work around sussex
thanks

Above comment is valid, but to try to comment on your question:
My Sti V3 hit 360/370 bhp but needed 550cc injectors, Walbro pump and SX regulator to fuel it.
At the time it has also a version * big TMIC which was 'ok' but heated up really fast when on the rollers. A minute under full power load was enough to cook the charge air.
I have since gone FMIC and the time it will sustain 370 is far far far longer, would say 5 times more at least.
I race my Sti so this is important compared to a road car perhaps.
I cannot think of any tuner in Sussex but contact the good guys like AndyF who travel the country. He might be in your kneck of the woods at some time?
