a standard block is good for about 360bhp (had this on my wrx no problems!) the problem with wrx's is the gearbox. to much torque and the box eats itself inside out lol STI 6 speed gearboxs are good for 500bhp+

the mapper didnt mention the gearbox, he just said the engins internals are only good for abour 240 whp, or just under 300 at the crank,,
i no the boxs are bad as my classic running just over 300 had had 3 in the pads 2 years,,,
i was hoping to get this 1 faster than my classic, it has more mods to make it faster its just the internals that i need to no what they will take,,
id be happy with 330 ish,,,, if he will map it to that, he also said max boot he can set it to is 1.4 bar because of the engine is this also correct??
as ive heard them rum a tad more.

VF34 will be good for approx 340bhp and so would your engine (and gearbox if treated with respect).

run same block over 500bhp..
standard engine I would prefer to keep to 350bhp.. and gearbox should be okay depending on how hard you are on it at that too.
but done standard engines to beyond that.. two examples 397bhp and 401bhp on owners request and no issues. The 397bhp car has been running for a couple of years with no issues despite the owner trying to break it.

Garage Deffinatly mistaken.
Im aiming for somehwere close to 350/340 with very simular mods, and dayjavoo a recent rebuilt engine too for me. I'd hazard a guess at mine being 310-320 at the moment, but need a map tweak for the recently added mods. Unless im werong you will be limping around on actuator pressure boost for a good thou miles with a slow intergration of boost. Im running 1.35 - 1.40 at the moment after 2000miles bedding the engine in.
Ive heard that the gearbox should be good for 370bhp - 400bhp (maybe optomistic specualtion of other enthusiasts), but as mentioned above its the torque that kills it. Ive had to replace the NPS on mine as soon as i got it mapped the first time as these are 8+ yrds old on a bug and are prone for going when running more power.

No disrespect but there are a lot of TY754 gearboxes running at 400 bhp and more without failure. Obviously their life is reduced at higher power but a lot will depend on the driver's mechanical sympathy and the clutch in use. A paddle for instance is a big no no as the shock destroys the gearbox.

The 400bhp car Harvey... what Torque was this running at?

My daily driver is STi 3 Wagon. 420 plus bhp and 390 ftlbs and has had an STi 6 TY754 for the last 3 years, perhaps longer. It may need a clutch change as the existing clamp pressure is now not keeping up with the torque increase. Not very obvious at present but I occassionally have slight progression of revs at max torque, up a steep hill locally. Just occassional. Over a 3 year plus period the car has progressed from 372/355 to 422/396. Probably done upwards of 36k miles on the STi 5/6 box in that time. Standard pistons, Eagle rods, ported the heads when I rebuilt the engine. Ground crank with ACL bearings. 740 injectors, my tubular headers and uppipe and a turbo I put together as a hybrid.
Paddle clutch is a big no no for me.
My STi 6 Wagon that produced 585 bhp/474 ftlbs at 2 litres on race fuel ran the O/E STi 6 box for 34k miles and the only thing I replaced on the gearbox was the centre diff. That now has a Forrester six speed from an M/Y 07.
