370bhp blobeye wrx??
okay my wrx is on 351bhp at the moment running fine,its got an afp 18g turbo with supporting mods on but its a bit laggy for my liking!
now all i want is to reduce this lag abit and i will be happy! i want to get the tgv deletes off an sti,harvey ported headers and then a map tweak,guessing this will roughly take it to 370bhp plus more torque,is my block upto it? i dont thrash it but like a good blast now and then!
and before people say it i dont want to sell it and get an sti!and im not worried about the 5 speed either! just dont want the engine to go bang.
has anyone got personal experience and ran high 300's on standard wrx's?
thanks

I ran a 350+ wrx for more than five years. Std box was fine all the way up to 390hp.
In those five years I had zero engine or gearbox problems.
I didn't do many launches, but the mid and top end power range were regularly exploited. Also did five-six track days on this setup.
I also ran an exedy pink clutch with an API lightened flywheel.
Obviously I ran it knowing that it might blow up, but a rebuild wouldn't have been an issue.

I have a near brand new wrx bottom end in my 2005 with cosworth forged pistons which apparently is good for 380-400. I'm currently running 350hp on an sc36 turbo. I have an sti inlet manifold (tgv deletes) and a front mount (ready for track days,etc) going on soon so the car will need a map tweak...... I held it back at 350 last time for the gearbox, what would people recommend power wise? I really could do with the gearbox not letting go for a little while due to all the other money spent recently but it wouldn't be the end of the world as it will need upgrading eventually anyway

The con rod bolts are the weak part [ weakest !! ] in a WRX motor. They are never good above a line of about 350 hp - when NEW. Break one and it will cost money.
The standard pistons aren't great up there either. BUt it all depends upon the mileage, service history and so on of the donor engine.

Obviously it's a calculated risk, and everyone is risk averse to a different degree. Personally, I'm happy to rebuild the engine and change the gearbox if either goes pop. Until that happens, I don't see the point of spending extra on it for the power levels mentioned.
My car is obviously not a day to day car, so downtime doesn't matter to me other than that it's annoying not to have a weekend toy.
