What can I get out of this B16A with out cracking it open.

[Kurt04]

Ok, I just got a '91 hatch with a B16A in it. It already has a GReedy header, test pipe, and Tenzo catback. It has a CAI but its hella short so I'm gonna look into something better. So my question is what can I do to get some more power out of this? Fuel rail, injectors, TB, Ignition system, anything else? How much, if any, improvement would I see.

I don't want to tear into this motor because this is my only car at the moment and I plan to build another motor from the ground up, eventually.

Well after intake, header, and exhaust there aren't any other bolt ons that will yield you power. The stock fuel rail and injectors are just fine.

The next thing to do would be to build the head up...I guess that's kinda tearing into the motor..but it's not that hard at all. Get some more aggressive cams like stage 1 skunk2's and figure out how you're going to tune them. The b16 is definitely a fun little engine...but unless you plan on ripping into the engine a bit there's not too much more you can do with it.

Ok. I think my first step will be OBD0 to OBD-1 conversion.

get bigger tb, a good IM (if not do a litle p&p job on the stock one), some NGK iridium spark plugs and something to tune your motor.

As stated by gurusan if you don't go with some crazy internal build stock fuel rail and injectors are more than fine.

you are not going to get much additional out of the motor if you do not plan on doing any internals (at least cams and headwork). If you already plan to build another motor on the side, then I would recommend just saving your money for that new motor *OR* only doing modifications that you can transfer over to the new motor.

This is one reason why I like doing suspension work first. Even if you are unsure of your plans for the motor, you don't end up losing any suspension work that you have done.

Ya, Suspension is pretty much done, car has Koni yellows, slip-on coilovers, and Suspension Techniquies swaybars. After the OBD-1 conversion I'll prolly look for a head to build.

well said..

i woudlnt waste money on TB or fueling unless you had some good internal work done.. flow velocity and quality would suck with a non built engine..
