I studied your pictures closely and kept this thread open throughout the project to compare my progress and see how much further I could take it. Other than screwing up the first time on the upper plenum (shaving away the EGR tube, but it turns out I wasn't going to use that one, anyway), I looked at this as something I'm only ever going to do once, so I might as well put in the extra time to get it as close to perfect as possible. Having the spare manifolds to do the work without neutering the car was obviously a big luxury in that respect.
It does feel really strong, but I'm always hesitant to make big claims that can't be verified with any before & after data... My gut feeling, though, is that the car as it sits would smoke a '94 fresh off the showroom floor if I could go back in time. I'm not on instagram, sorry.

Hi and thanks for keeping old threads alive")
I have been looking all over for 1UZFE intake porting already done and or how to do it as I have just had to swap out my sc400 oil pump sump sucker (upper flange cracked sucking air) failure. I have all the old kit in bits here and so I may as well do the porting on that. Looking at it and reading your thread it seems like this is a worthwhile mod for some smooth midrange gains in performance maybe even a few extra GG's too.
