Next Power Step?

Handle over 400 with the right mapping.

350+ is remapped RS2 spec, which is all bolt on and is heavily detailed on many build threads. Can't go wrong and that's from experience

The million times question

Have you used the forum search tool?

There are many threads asking for the same.

I'd stop boosting stock turbo by 1,6bar
You don't need wastegate unless yours is worn.
Volvo k24 7400 seems a good 350hp choice turbo.
You'll need bigger fuel pump, injectors, software, and if you can exhaust ,IC... I'd not touch the camshafts

I've got an AAN engine in my 80q, running around 285bhp. It is stock other than 034 coilpacks, FMIC, chipped ECU, and a screamer pipe + cone filter, current boost is 18PSI.

My question is, what's next? I'm pretty new to these engines but a craving for more power is pretty natural

How much power can the standard internals handle? How much boost can the standard turbo supply? Could I just change the waste gate and gain more power? New injectors? How beneficial are 7a cams? Is there a straight swap turbo? Etc etc...

Looking for a reliable 350+bhp ideally, and as cost effectively as possible... Rather not go for a full engine rebuild if I can up the power safely!

Fire away! And forgive my lack of knowledge and laziness for not trawling the internet deeper for answers
