Just took the GSR head off, my plugs and valves are white! And the plugs werent white 2 weeks ago when i installed the motor! I think im runin lean. Im using b16a1 injectors, and pr3 ECU...could this be the problem? WHat should i upgrade? Should i get a chipped ECU? also....someone said theyd trade me heads....a b16 head for my GSR, no cams involved. B16 heads flow better right? The b16 IM also right? I hate that GSR manifold..should i trade?

If the exhaust valves are white that means that you are running lean, but the plugs are usually a grayish color when you are running lean. Looking are the way down the plug porcelain and that will give you a better overall color than the top of the plug.

Grey plugs are good, not lean. White plugs are lean.
You want to have a grey color to your plugs.
Too dark your too rich, too light your too lean....= grey

Correct color is a light brown color on the porcelains, and on the exhaust valves would be a red-brown color. You maybe talking about the electrode. The base of the porcelain will be a gray color with white exhaust valves for lean condition.

They are white, and so are the valves. And the were nice and grey 2 weeks ago. What should i upgrade guys? fuel pump? chipped ECU? look for bad sensors? injectors? fuel rail? its using b16 ECU and fuel injectors, and i dont know what pump it is.

what fuel system are you using now and is the ecu chipped?

that maybe your answer

I dont have a Fuel pressure gauge T'd in there. Its a stock GSR fuel rail with b16a1 injectors. The ECU is a b16a1 PR3 OBD0 computer...unchipped. All this stuff i borrowed from my b16a1 which ran just fine. But apparently its not enough for the b18c. 2 weeks after installing the motor the plugs are white and so are the exhaust valves. The previous owner had this motor wired OBDI with a chipped p28 runin the show, and it wasnt runin lean. I wanna know what to do to fix this problem. Im thinking just chip the PR3 with a more fuel map aggresive chip. Any recomendations? (mugen, skunk2, hondata.......?)

Just think about it. The ECU and fuel system you are using is fueled for a 1.6 litre motor, that produces 160 hp. Now you are asking that same setup to fuel a 1.8 litre motor that not only produces a crap load more torque, but also 180 hp. Yes you are running lean. If it was my car, I would start with a Mugen program for your PR3 ECU. It runs quite a bit more rich than stock, and would likely make the motor run much better.

I always wonder why people think 17ftlbs of torque is a "crap load" more.. ??

First of i would not trade that gsr head for a B16. The gsr head makes about .2 more compression than a b16 and is awesome when paired with a skunk 2 manifold. As far as the whole running lean thing, Honda motors are set up to run lean from the factory. These are gas mileage cars and they love to run lean. As long as your not getting any spark knock or detonation i say dont worry about being a bit lean. A bit lean will actually be a little faster than running rich. Just gotta make sure your timing goes with the amount of fuel. Also remember that you could be lean under normal driving(constant speed, or even throttle) but then it could be completly different under full throttle. Grap yur self an FPR and a nice 190 walbro pump and go from there. Dont mess with generic chipped ecus.

Because 17 lbs/ft is 13% more torque, and that's a crap load when you're talking torque.

Not exactly how I look at it, but each to his own.
