If you want to bump the output then tiwn 40's 285deg cam, flowed head and tubualr maniofld will see you just shy of 100BHP

As j1400 said... Apparently you can get 120mph out of a 1.2 8v on throttle bodies so long as its on the right gear box...

Throttle bodies use electronic fuel injection, you have one throttle body and fuel injector per cylinder and an ECU which controls fueling and ignition. Downfall is they are pretty expensive and cost a fair bit to set up...



I guess you already have carbs on the engine, so I guess you should probably upgrade those to 40's or 45's and upgrade the camshaft...

www.jenvey.co.uk are the main suppliers of TB's.

Carbs are a mecanical version, or rather TB's are a electonic verison of carbs

120BHP out of a 1.3 is 300deg cam, head work, big valves, tubular manifold ARP's and a 8k rev limit.

Or just buy a 1.4 MPi engine, remove injection, add 300deg cam etc....

Much cheaper than head work on a 1.3

I have a 1.4 Mpi engine in the shed if you were interested.

ok so at a guess how much bhp would the 1.3 have if i upgraded the carbs to 40's what else would be cheapish but effective?

T40's and a 285 cam, you'll be around 100BHP this is the same spec the nova sports ran.

look on piper cams, kent cams

Or use the tutorials and FAQ's forums and have a read about cams on there.

It's a higher performance camshaft. Basically the valves stay open for longer when using a performance camshaft, the time is dependent on the shape of the cam lobes...
