Modifications for the Rover 45
We look at the latest Rover 45 tuning parts and recommend the best mods. Read our complete 45 tuning guide.
Available in standard form with power of upto 147bhp (depending on the year), so this goes to show the tuning potential of the 45. From this you can increase the power from anywhere between 161.7bhp to 249.9bhp with modifications varying from a few DIY mods to some pretty major engine work. The higher you go the more unreliable the car will be and you should expect to have to rebuild the engine regularly if you want to extract silly power. A big forced induction upgrade would be needed to push beyond the 100bhp per 1000cc limit.
If you have one of the lower powered 45s you should think about an engine swap with the engine from the 147bhp 45 Hatchbacks. The more powerful 45s respond well to tuning mods. Car Tuning Guide have been impressed with the addition of stainless steel exhaust systems on the 45s , if you want to improve your top end go with an air induction filter. You should also get a better fuel pressure regulator such as those supplied by FSE
The next level of modifications involve taking more aggressive action. The 45 responds well to a fast road cam which is one of the best value mods out there. Internal engine modifications that should be high up on your list would be polishing and porting the head.
The most powerful 45 Hatchback in our database offers 147 bhp. From this you can increase the power from anywhere between 161.7 bhp to 249.9bhp with mods we have outlined above.
Rover put together a nice package but the turbo 45 owners have a real tuners dream. A remap and Intercooler will add a lot of power to the engine and in some cases you can double your power. The 45s come in various power levels right up to 147bhp. On a motorsport prepared 45 it is possible to achieve power figures of anywhere approaching 191.1bhp to 279.3bhp. But this sort of power requires some pretty heavy investment and a hell of a lot of engine work. . Suspension improvements can dramatically increase the road holding and cornering of your 45. Although lowering improves handling you should stick to a drop of 35mm.
We will have more detailed 45 modification guides in the near future. Please check the site regularly for updates.
