Alright had to track you guys down, need some opinions and help. I recently picked up a 94 fd, and im new to the turbo/rotary world. car background info: 3 inch greddy ehaust w cat,basic K&N,Greddy BOV, motor and tranny rebuilt 20 k ago, ceramic seals?(better than your standard apex seals?) supposedly the Japanese motor(not sure, you guys know where I can check the nuumbers?) was original owner, 20 years head tech at mazda. weekend driver, all original. about 116 k. the common occasional pop at idle

drove the car every other day for about 3 weeks then I began to notice every once and a while erratic power output at almost 3k on the dot,(whehn the second turbo spools right?) fall for a split second and then catch itself. completely random, couldnt duplicate it in my driving. about another week after noticing it, took it out for a ride, caught the power in first, but into second nothing at the 3 grand mark, felt like an NA. looked at it again today, it felt like on every 4th rev only that there was 25% of the normal power, other than that, nothing. Im not sure if its my imagination but somtimes it sounds like a constant hiss under the hood like a pressure leak, but you can only hear it inside the car.guys, please tell me im not buying a turbo.oh, a bit of light oil residue on one of the turbo housings and some of the piping fittings.

my plan of attack was to put in a front mount intercooler, Ive heard the stock ones have a problem blowing due to heat/ plastic/pressure, that and the piping would get rid of all the plastic, rubber, and free up some space.any help would be greatly appreciated, this is my first turbo, and first rotary, and im in love.

if you guys have any ideas on what to go over, ill keep you updated.
