i had an ss autochrome manifold on my 300whp gsr and i boosted the wastegate right off of it one night under normal driving. their manifolds ftl. if you want a cheap reliable mani go cast. for 200whp there is nothing wrong with using dsm bluetop injectors, they work fine after you wire in a obd0 resistor box and you have room for improvement on them if you want to up the boost, these can ususally be had for less than $100.00. if u use these or any peek and hold injector there is a step by step how to on honda-tech. good luck ! im doing the same thing piecing a kit together for my 99 gs right now. im shooting more in the range of 260 to 300whp accept i will be adding some crower turbo cams / cam gears to the setup. gl !
