Martin,

If your current injector duty cycle is peaking

@ 86% then you're already out of injector going by the
![](./images/smilies/spacer.gif)
'safe' rule of thumb of not pushing injectors past 85%DC

, so really, you'll need to go bigger, either drop in 850's or a top feed set up with something else

(plenty to chose from, another topic entirely)

As for the turbo, sound advice from Ashley there re peak power vs drivability, I'm sure a car with a wider, flatter power band would feel a lot faster and be better suited to what you want from it

There are options other than a whole new

'kit' for you though.

Many turbos will use, the same footprint as your current one so would be able to be a direct swap.

As Ashley said, a smaller gtx3071 wheel will flow a little more air than your current 76 and spin up faster, maybe more what you're looking for.

A BWs252sx-e has a smaller wheel still

(but a larger turbine wheel, more evenly matched than the Garrett.

) but still flows more air than the 3076

- this is the turbo that Sheppy has, and TBH the one I wish I'd bought.

The next step up would be a S257SX-e, similarly sized to the 3076 but flows much more air, and every B2B dyno chart I've seen shows them spooling faster than the equivalent Garrett, despite not being ball bearing, and making a fair bit more power pretty much everywhere.

There's lots to think about.

Sheppy got his BW from AGP turbo in the states, they offer a garret Footprint housing with their turbos, so you'd literally be able to remove your 3076 and bolt up a new one to your manifold adapter/downpipe.
