My brother tried tuning the 1.3 in his mk1 & gave up
engine was from a mk2 Golf, so higher compression than a mk1 & hydraulic tappet head
First off he put a Polo GT manifold, de-cat downpipe & custom single box system on it….. made it rev a bit better, but didn't seem to give it any more power
Then fitted a Weber carb (DMTL) & just could not get the jetting right….. it was either flat & good on fuel or fast & rubbish on fuel….. even went to Bogg Brothers & still not great
He converted it to multipoint fuel injection not long after…… used parts from an NZ engine code mk3 Polo (the one down from a GT)
…..
Hardest part to converting the car to fuel injection was the wiring…… well not really hard, but takes time to strip a Polo engine bay loom back to the minimum needed to run the engine……. think it was 4 wires on our Matt's car
……
You can probably get a cam & high compression pistons for a mk1's 1.3……. but it maybe expensive
You can build a 1391cc Polo GT engine using a block from an early mk3 Golf 1.4 (or Ibiza) & 276 degree Schrick cams are easily available…… this would give you nearly 100 bhp & still very good on fuel
I've got on of these engines & used it in 2 different mk3 Polo's……. 60 mph in just under 8 seconds, 1/4 in 16.4, real life 120 mph on the track & nearly 400 miles to a tank if you take it easy

It seems that if you have a 1272 mechanical-head engine, you're stuck with <70 bhp, unless you get handy with a Dremel on the head, or you can stand the cost of getting bike carbs set up properly

you can spend thousands on lightened flywheels, head work, cams and carbs and still only get a fraction of what you can get with a gti engine with light work…
if you want to stick to the stock 1.3 engine then stick to it as it is, you will only waist money in the long run.
im saying this in the knowledge that i have tried on other cars to release more power but in the essence of things all you will end up with is highly tuned small power, its great saying "yeah its fast for a 1.3" but you will still get people steam past you
i know how frustrating it is, im only 21 and i got a 1.1. all my mates got new cars with 1.7s and 2.0 ltr engines and they leave me behind all the time
i dont mind, mine doesn't brake down
and one day i will drop a big block in it and smile as i pass them all!!
sorry if this seems like a bit of a lecture but i would hate to see you throw the amounts of money away i have when you can achieve big power at small costs with just a another engine
dont hate me
cheeers!
