i may have missed something here but i was under the impresion that the only difference in the h and the t was the size of the inlet.i thought the h had the standered inlet and the t had the bigger 3in inlet.

Interesting. I was thinking about getting one of these myself because I'm on my 3rd OE pipe so far and don't want to pay £200 for a pipe where I'm going to block most of the outlets off anyway. Do you use a VTA dump valve, or keep it recirculating and somehow modify the Prodrive pipe to take input from the DV return?

inlet size - convenience of fitment now really as it seems to make little difference to power output

Marmski - I have the 321H on a standard 03 STI engine. If it's the 'H' you're referring too (I think it is when you mention 400/400) then here are my thoughts:

Can a standard MY05 STi Type UK take this turbo/power with its standard clutch? - Yes, providing you're not into full-blooded standing start launches

As i understand from various reading other supporting mods would need to be:
650-750cc injectors - yes, 650s are perfect
New Headers (im assuming i can still keep un-equal?) - yes, tubular headers really lifted the performance of my H compared to ported OEMs
Decat system - I run hi-flow sports cat and have just squeezed out 400bhp
Turbo - Yes
Walbro 255 Fuel Pump - yes
Remap - absolutely!

And then the engine will produce a safe 400/400 on Tesco99/V-Power? Should do; I use a bit of NF for extra safety. Obviously at 400bhp, the engine will be under more stress, but I gather there are several standard engines running well at this power output - the key is good mapping

With regards to other upgrades, are the brembos upto this kinda power? - not really; I'm using Performance Friction discs and pads - absolutely amazing! (suspension is standard shocks but on STi Pink Springs). Also STi panel filter in.

This just sounds like a perfect turbo (why doesnt everyone use these?!!?!) - guess lots of people are put off by the extra outlay compared to some other turbos
