So even if the manifold was a good half of the restriction, then chances are it's only a difference of about 5 to 7.5% in operation between inner and outer cylinders, if that. I don't think I've ever seen head flow data for a head with no valves. I do know that a stock Gen2 head at 0.350" valve lift will flow a god 20cfm more than the intake manifold does. A fair amount of the problem is that the air is dumped in "straight down" the centre runners and has a less direct route involving another 90 degree turn to get into the outer two runners. Mind you I can't say I'm too concerned since I've got a Gen3 setup and my head flow characteristics are nothing like a Gen2 especially with 1mm oversize valves, tidied up throats and 0.400" lift cams. I was just offering the info to save a misunderstanding of the basic principals from costing the person who started the thread an engine. To be safe you could just add a little more fuel to the centre two pots to keep A/F ratio even across the board. I know I'll be doing this with my engine. On the otherhand some testing with individual oxygen sensors in each exhaust runner would put this kind of discussion to rest. I believe there are a couple of MR2 owners working on this at the moment. [Report message to a moderator]
