Intake manifold swap idea...

[thewoahna]

OK, I got this idea from one of the guys at www.cb7tuner.com and I wanted to get your opinions on the matter. I was thinking about swapping my stock LX ECU on my 90 5-Speed with one from a 92-93 Accord EX 5-Speed. I was also thinking about swapping my stock intake manifold with one from the 92-93 EX (with f22a6 motor). From what this one guy says, I can gain about 10 hp with this. I have done some research and I can get both the ECU and intake manifold for 275 shipped. Would it be worth it? He says that it will bolt right on, without any mods. I only have 80k on my motor as of now, and I don’t want to do anything that would put the rest of its life in jeopardy. If I was to do this, should I have the manifold taken to a machine shop to have polished before install? Thanks for your input!
