Ok lets break this down:
You don't mind paying over the odds for stronger bits? Lets call over the odds 15%?
You can buy a complete F7P for £50. £50+15%= £57.50. I don't think you'll get many stronger bits for that 
But seriously. Rods can be got for 500uk£ easily. 200 if you don't mind waiting and have all the dims to hand. Pistons are 400 or again, 250 if you can wait and have your own designed.
Rod bolts are about 50 quid. I think you can get a steel crank for 1200ish |

And one more thing, standard bits have been proven to last 150k when thrown together by a renault monkey 15 years ago. Everyone blabbers on about lightening this and balancing that but for a standard rebuilt engine its just not necessary |

10:1 which is stock is the highest I would go on a road car witgh a turbo, you can ruin 20:1 + on dragsters etc but thats only for a few minutes lifespan. |

Std components will stand upto the abuse, at most if your running some decent boost run forged pistons.
The high bearing loading will be your main problem, renault's sintered ally tin bearings are soft as cheap and crap. |
