   My friend and I have aquired a 16v 106 GTI Engine that we hope to Tune and put in a French Car of some sort.
   
   We have both experienced Engine Conversions etc and have owned Various Saxo's and 106's Which appear on this Site.
   
   Our Aim is to build a Fast Road N/A Car. Possibly 205
   
   We were wondering if it is worthwhile doing bottom end work i.e Lightened and Balance Crank Lightweight Flywheel.
   
   Many Thanks

   Bottom ends are generally balanced well as standard. There are plenty of people revving them to 8000rpm for years with no problem. People have had stock bottom ends way past that. Actually one of the best things about these engine is how well they are counterbalanced and in so there great harmonics. Unlike many engine that require substantial harmonic dampers. If you start doing substantial changes such as knife edge the crank or substantially lighting it in general will just give you problems.

   Thanks for that Mate glad i didnt go spend alot of money on something that wasnt needed.
   
   Any more info on how to get the best out of an N/A TU Engine?
   
   Besides Cams Throttle Bodies.
   
   Thinking of a Gasflowed Port and Polished Head maybe skimming the head also?

   how much power do you want, how do you want to get it.
   
   If you dont need big power you dont need to do alot to the engines.

   Basically our budget is £200 a Month Throughout The Winter.
   
   Once we get an idea of building a car it may get rebuilt next year as a boosted engine.
   
   The Way we are thinking just now is alot of headwork, a Set of Cat Cams, Mapped and Stainless System which should be pretty much enough for us this year.
   
   But if anyone can suggest anything that would benefit the build let us know

   Get a decent stanalone first, if you plan on changing the spec/upgrading often this will be cheaper to get maps tweeked on etc...
