My 91 Si w/ B16A I,E &H. What would the next things I should look into for performance N A. As far as manifold I was thinking just go to dealer & get a integra Type R manifold but wasnt sure how much this would help or take another route. Someone also said I should put a type r tranny in also. Let me know some of your suggestions.. Holla

 

If you wanna go power first, I would go Skunk2 intake manifold, AEM fuel rail, clean or new injectors (not high flow though), adjustable fuel pressure regular, bolt that on, and BAM! like extra 10-20 ponies.
Or you could do port/polish head, comp or skunk2 cams, retainers, valves, springs, and cam gears, and with tuning, and BAM! 20 or more ponies.
I myself would do suspension first though, that can really shave off the seconds. Good luck!

 

screw all that... just buy a turbo kit, get some low compression pistons, and call it a day!

 

He said he wanted N/A performance... But if it were me, yeah screw that, just get low compression pistons, stronger head gasket and turbo kit. BAM! 100+ hp!

 

IF it were me, I wouldn't just do bolt on. Right now I am running NA, and I am in sort of the delema you are in. I think if I were you I would sleeve it, bore it, pistons and rods, hone it, clean it up. Make it a rock solids engine, then start putting in the bolt on stuff. Take your time and do everything right though. Don't jsut say, " hey I got money to burn , ummmm let's buy a fuel rail", because your car may not even need it if you aren't going to pump enough fuel for it. You need to sit down and see what your plans are.

 

10-20hp with an i/m and fuel parts. wow, i would LOVE to see that.
