Got an idea brewing in my head, Found a 99spec corolla 4efe with yellow injectors etc today at work, 39k on it, immaculate. Am i right in thinking these are 88hp standard? and also planning on while its sat around, get the head skimmed and port and polished, turbo valve springs etc... Any engine gurus out there that can say how much would need to be skimmed off the head to make a lump more power, and how it would work out with a thin TRD headgasket? And also any other things i could do while its there to be played with... P.s i know its an engine thread, just want a few ideas then it can be moved into there?? Thanks
