Below are the different mods I have briefly looked into but need some guidance on which route to take. Potential Performance Mods

• Bigger Turbo Compressor Wheel

• Bigger Brakes

I have bought the 535d injectors as I've heard that they are a straight swap but have not installed them yet as I'm looking at other mods to do at the same time.

I am going to get a quote from a fabricator to make a bespoke enclosure for the cone air filter so that I can route cold air from the grills to the filter.

I've got a quote for Quaife LSD which I'm probably going to get. The price is £954.91 for the part.

I have also spoken to Turbo Dynamics about upgrading my turbo and they told me "we never really developed any tried and tested upgrades for the 120d (or any of the 2.0d BMW variants), so whilst we can certainly rebuild your turbo and upgrade it, we haven't carried out much testing so wouldn't be able to guarentee any power figures. A typical stage 1 hybrid on these engines should give around 250hp, and the price to upgrade your stock turbo would be approx £400 + VAT, depending on condition" so I was thinking of sending my turbo to them along with a bigger compressor wheel. I think they rebuild the turbo with upgraded bearings and some other stuff but I'm going to ask for a list of what the rebuild includes.

I have seen some "hybrid turbos" on Ebay (links below) which could potentially be another route.

I have also briefly looked into the water-meth kits, I've heard they work very well on diesel engines but I'm not sure on what options would be best. Below are the links for the kits.

I will be looking at removing the soft top roof, along with reducing weight wherever else I can in the future when I am looking to buy a new car (I'd keep this one as a drift/track car). I would also like to get a roll cage made for it. Then either a bespoke removable hardtop that goes over the roll cage or a removable clear plastic cover to go over the roll cage to stop rain coming through. I would also want 2 lightweight seats and a lightweight racing steering wheel.
