    Oversize Valves cheap!!

    What Toyota valves will fit the GS 1100 series engines? I heard that its feasable and much cheaper than Kibblewhites. Thanx Mike

      Mike,
      It my be a cheep alternitive but remember when you increase the valve size you increase the weight of the valve which increase the chance of valve float or you have to use to much valve spring pressure. So really you need the oversized valves to be made of a lighter material that is why they make the oversized valves out of lighter stainless steel. The cheep way is not always the best way. I use the Ferrea valves.

        Perfect Xchange

        Was told that the Valve was perfect for the GS 1100 intakes, I usually like to make the intake a bit bigger or a lot if required, I have a few heads now with o/s valves, Just the prices are going up kibblewhite valves had a steep jump. I want some nice quality (toyota is nice) and would backcut the valves ect, would weigh nearly the same as stock, Thanx Mike

            I was wondering about the same thing
            Why not just use GS1150 intake valves
