how big is your biggest 1100 piston GR? 120thou may encourage some people to build 1200cc twin-Kam bimmer engines yeah? now a turbo-charged 1200cc twin-Kam 16v would have to be a nice little toy yeah? |

now a turbo-charged 1200cc twin-Kam 16v would have to be a nice little toy yeah? I played around with some calculations with sleeving a while ago with a standard bore 1275 , using a stock 2.7950 inch bore Sleeve would require a 0.381 bore ( 15 thou overbore ) and with the sleeve thickness 3/32 inch 2.3813mm would give you a 68.6117 mm 2.7012 inch bore, so 1202 cc with a standard stroke . |

Hi Matt I have .020 .040 .060 .080 .100 over size i did'nt go .120 over because the std gasket hangs into the bore to much,even with .100 over it's on the limit but that gives you 1183cc. Graham Russell |

oh that`s fine GR , 100 over is plenty big enough, i actually already have prepared here a Bimmer-twin-Kam-ised small bore block ,,, sitting right here ready for the job,,, & it`s already been bored to 100over,,, so sounds like i just need to dig out one of my 1100 cranks & buy some of those juicey 100 oversized 1100cc slugs off you & i can start building a sweet little 1183cc Turbo-charged Twin-Kam 16v donk,,, or will i just make it an 8v??? yeah maybe just make it an 8v & keep my 16v heads for the big donks yeah? Hhhmmm should be a sweet little thing & it is a 998 block with 998 engine number on it so any smarty-pants mini person will "think" that it`s a 998

Im a noob to the forum so what i will say is probably wrong 
I believe a 16V turbo sounds like an engine that wants to rev and an 1100 crank doesnt want to rev.So a poor match.A 998 will rev better so possibly make similar or better top end hp. |

as far as I know a well balanced 1100 will rev just as well as a 998 so long as it's for road use, ie under 7000rpm. Yes a 998 will rev higher than a 1100 but the power band/range is not at max rpm so their is no point in reving thee engine that high anyway. Plus if your turbo is set up correctly it will build boost from a lowish rev range (around 1500-2000rpm ideally) so it will probably run out of puff and make it's max power before it reaches the max rpm of the engine. |

An advantage of using the 1098 crank with a turbo motor is you have reasonable torque when it's off boost, even if the C/R is a bit low and it's a big turbo. With turbo you don't need a zillion rpm to get big HP anyway. Look at what Pristic and Benjamin both got, around 130+HP at the crank. This with 5 port heads and RE13T cams. |
