Around the 380 - 400 mark

Jon T

What top mount would take my hawkeye sti over 500bhp. The engine can take it but the ic is holding it back

Realistically, none. You're better off going with a decent front mount if your aiming over 500bhp.

Roger clark head studs
3in miltek exhaust turbo back with sports cat
Manifolds aftermarket but domt know what make
750cc injectors
Turbo dynamics mdx pcm 450
​ turbo.
That all i can name off the top of my head not getting the car till tomorrow will a good look at all the invoices.
I know when the engine was built the previous owner wanted it 500 bhp safe.
The turbo should be good for high 400s but the intercooler wont

FMIC I'd say or you're not going to do the engine justice.

As the others have said, you'll be wanting to go for a front mount with that sort of power. I'm not a fan of front mounts on imprezas (they always fit badly and I don't like hacking bumpers to bits) but at 500, you'll have to imo. Even an uprated top mount won't do 500 bhp justice.

I know but i dont like the fact that your front mount becomes your crash bar and the are easily damaged.
Love the looks of a front mount but i dont know for a daily driver

You could buy a zunsport grill to put over it mate, would give you some protection.

Jon T

Was gonna fit a full grill set are they that strong

Well, they won't make much difference if you plough into something, but they'll protect it from things like leaves and sticks, stones (to a point) and other debris. Having one would make a difference over not having one, so I'd go for it.

Tidgy

if you hit anything hard enough to damage the core theres gonna be plenty of other damage and it would have done the same to the rad.

at that sort of power 100% front mount.

Jon T

Will let my bank balance recover a bit and front mount and remap it is
