Hey, looking into buying a 1275cc as my first proper car to do up over the next year or two but would like to ask about some possible issues before I invest in one.
Due to the heads only being 2 valve per cylinder and with reduced air flow, are there any reasonably cheap ways to switch the heads out for a better flowing 4 valve per cylinder head? I heard somewhere that you could put 4 valve BMW heads on a regular block with some tweaking, but not sure how feasible that is without sending it off somewhere.
Another factor is the tranny. The MG Metro that was designed to replace the mini, that only had 94 HP with a turbo, had to have reduced boost in lower gears due to the tranny not being able to stand up to the forces so I can only assume that the earlier mini would have an even weaker transmition? I've also read a few people having trouble with 2nd and 3rd gear wearing out quite fast. Would I be looking at replacing the entire thing if I wanted to go to about 120whp? It would probably cost more than the car if so
Alongside the tranny is the flywheel. I don't know much about fly wheels other than that they store energy and really wouldn't like that to disintegrate if I upgrade the engine.
Thanks for any info, all is appreciated :)
