Hello and a warm welcome to TorqueCars, nice to have you with us.

We get asked about adding turbos a lot so have a look at this thread which covers the basics. I have to admire your ambition though! And I hope you pull it off.

Cheap turbos can be purchased from breakers yards which are ideal for a try it and see type project.:bigsmile:

Please note that I don't think it is worth adding a turbo to an old car with a small capacity engine. There is nothing stopping you but the money and hassle will just not be worth the power gain you get. It is better to just buy a better car for your tuning project.

Adding a turbo is a major engineering task and without a kit with full instructions and all the parts you need there is a big risk of blowing up the engine. Expect to spend 50 hours upwards on a project of this type. This is not the sort of modification unless you are mechanically competent.

It is worth looking at superchargers as these are easier to install than a turbo is.

The best mods for a car engine are as follows.

Internal work yields the biggest gains, head work like porting polishing and 3 angle valve jobs will maximise the airflow and raise the power.

If you want to go to the max then cryo treat the block, get it rebored and look into blueprinting and balancing as well.

Bigger valves are an obvious addon but not all engines are suitable as it depends how close together the OEM valves are.

A fast road cam will yield good power gains, especially in the top end of the rev range. Don't go mad though a profile of up to 270 degrees will give the best gains without the engine becoming cammy.

The most popular power mods are induction kits (which are questionable as power mods but they can sound nice if that is your sort of thing) and sports exhausts with sports catalysts or decats.

To keep the car legal I'd recommend a sports catalyst rather than a decat.
The last mod should always be a remap as this will allow you to fully realise the power gains on offer from your mods. Turbo cars respond very well to remaps.

It's worth having a read of the articles on www.torquecars.com/tuning/ for more information on these mods and what the terms mean.
