So, after numerous people-related issues and let-downs, Volvo finally went to a specialist for an engine rebuild. After engine tear-down, he'll check and measure everything to evaluate what needs to be done. I decided for complete rebuild using original parts with the exception of using forged rods.

Now, I have also been thinking of doing some other upgrades, as the engine will be out:

- NA intake intake manifold
- 2.5T exhaust manifold (S60R, XC90 2.5T ...)
- Maybe NA cams

Car already uses a larger turbo and a Ferrita 3 inch downpipe so these mods probably make sense, especially since they're relatively cheap. My goal is an optimised setup capable of cca. 350 HP using the least amount of boost possible in order not to stress the engine too much.

I do have some questions regarding the possible bottlenecks:

1. Air Intake
I will remove the BMC Carbon intake and use the stock airbox (MOT is a bitch where I live). I intend to use performance filter panels (such as K&N, BMC or similar) in order to allow the engine to breathe better. Any ideas what figures are possible with a setup like this at best?

2. Injectors
Same question here - what are the R fuel injectors limits?

3. Fuel / oil pump
Again, same as above - can I keep my fuel and oil pump and reach wanted numbers without any issues?

4.Any other possible limiting factors? Clutch?

I realise tuning the car up to 350 HP is far from big but I still wanna be safe.

Thank you for helping me!
