What is the engine type of the 1300 128 engine that you have found? engine type/number is stamped on the rear face of the block, right hand upper.
This and a few other visual clues will tell you what the standard output was... which for a 1300 can range from about 60hp thru to 75hp... but most of the changes are bolt on, so you should be able to source any parts you might need...
If the engine has a 32DMTR two barrel weber carb, and has a twin outlet exhaust manifold, then it will be up or over 70hp... the rest depends on which inlet manifold and camshaft are fitted.
128 coupe/ rally has the best intake manifold standard... I still see them occasionally on ebay... so they are around...visually from the outside it has the mounting holes for the throttle bracket horizonatlly aligned.. sholud have a part number cast on the outside... I have manifolds around I can look at to confirm numbers if you want..
the 128 3p manifold has smaller ports... but can easily be opened up... the mounting bolt holes for the acc linkage are arranged diagonally... and of course the part numbers cast on the outside are goood clues as well.
The twin outlet exhaust manifold is worth around 8hp on otherwise identical engines...
If it has a single outlet exhaust manifold and a single barrel carb... its the 60hp end of the scale, but you can bolt parts on and make a lot of diference.
Simple enough to boost the output of an otherwise stock 1300 (which revs a bit harder than a 1500) to around 80/85hp with a larger 34dmtr carby and a 2inch exhaust system.... lighten the flywheel... simple stuff from the outside, without having to open the engine up (if you don't really want to)
A camshaft makes a fair bit of difference too... and having it in exactly the correct phase with the cank.
with a std 4 speed 128 box (which I think would be the simplest to fit) as the lower engine mount / cross member for a 127 and a 128 are very much alike... so a 128 lower engine mount onto the std 127 cross member...( that you might want to beef up just a little)
the regata85 5 speed (I think) will give you headaches with the extra length for the fifth gear extension... but otherwise is very similar to the 128 one in the arrangement of the inner "tripode" joints... once again similar to what the 127 runs... only slightly larger in a 128, and slightly larger again in the regata85.
You will need to shorten a pair of 128 axles (from memory of the times I saw the converted car) cut them on a lathe and reweld them when you figure out how much you need to remove
1300 and four speed is also the lightest combination... and with a 127 I think you want to keep the whole package as light as possible... using as many standard psrts as possible...
BTW X19 strut insert cartiges fit into 127 strut housings... you need to drill out the alloy dome at the top mounting to fit the larger shaft... but it works really well... from memory it took a thin (6mm) alloy spacer in the bottom of the strut housing is all that was needed. housing diameter / length is correct for the inserts, and it raises the damping rate up to about right for what you want to do...
128 springs are the same coil diameter as a 127 too... if you need to increase the spring rate to compensate for the extra weight of the 1300 these might be a good staring point... 128 coupe coil is 6.5 / 7 winds (this is all from memory) and the sedan is up around 9 winds, but you can cut them, provided you bend the cut end down, you need a flat wind so the spring seats properly.
