MGB GT How much HP possible? Air conditioning?

Question

Hi,My mechanic and I are remanufacturing a left-hand drive US sold 1967MGB GT. You guys don't get this one back :-) We will stay with 4 cylinders. He thinks if we go to 2 liters, we cangenerate an honest 85 to 90 HP at the rear wheels on 91 octaneunleaded. I want to be able to keep up with Porcshe 356s and 912s atleast.Opinions? Should I consider a supercharger add-on as well? I likespeed and quickness. We will be upgrading the suspension as well.Also, reduction of HP ignored, are there any good air conditioningunits available for the MGB GT which fit cleanly and won't make theozone hole reach the Northern Hemisphere?We are in Southern California and it gets really hot here about 6months of the year.Opinions and experience sought.Sincerely,Jim Klein

On 1/9/04 7:30 AM, in article     "West Coast EngThere were several "stages" of racing tune back in the day, and, IIRC, the Bseries block was capable of a lot more than 90 hp! I don't have the specsfor the stages, but I'm sure someone here can help.

The is a very simple rule of thumb.Speed costs money.Next comes a very simple question.How fast do you want to go?What about a stage 2 gas flow head? Get rid of the SUs and fit Webbers, a new exhaust including manifold manifold. Replacement air filters so it breath properly.Then there are the engine internals. New cams? New pistons?What you need to do is throw loads and loads of money at then you can have the car of your dreams.Good luck with the project and keep us informed as to what you end up doing.

"West Coast Engineering" E-mail mailto:     and ask them for a MGB catalogue.I don't actually have a copy, but the similar catalogue I got for mySpitfire goes into lots of detail on the tuning possibilities.
