Having problems with your 1996 Nissan Sentra ?

'98 Nissan Sentra GA13 guzzles too much fuel - supercar-like consumption of 12MPG :-(. Newly overhauled engine - bigger pistons (.1 liter up), new piston rings, head gaskets, timing-chain, everything. Even the carb has been newly overhauled. Motor's running smooth and fine, but guzzles at an unbelievable rate and emits very strong exhaust fumes that goes inside the car when cruising. Also i've noticed the engine blows white smoke after 80km/h or 50mph. Any suggestions / recommendations would

I encountered a very similar problem before. Have your carburetor redone. I also spent a lot trying to fix that kind of issue before with the car I'm using (also with ga13ds). I overhauled the carburetor 2 times using repair kits but there are still the same issues and at one time things became even worse. Bring it to a mechanic who works with nissan (not necessarily in the service center) and/or is specializing in carburetors because there are a lot of things that may go wrong inside a carburetor. I brought mine to an expert in Evangelista Makati, Philippines ( well I guess your from the Philippines because I could not find ga13ds from other countries unless I'm wrong) and it only took about two hours without even buying parts, just some elbow grease, smashing, scratching, and some salvaged parts from other carbs- the whole process cost me Php1,800 plus travel expenses. Also, buy a good air filter and make sure that your air cleaner assembly is working properly, these kind o issues are caused by accumulated dirt in the system and it slowly destroys the carb. After having all the repairs done, invest in one aerosol can of carb cleaner and use it on your carb maybe about once a month (I do it that often) it keeps performance as close to optimum as possible and prolongs the carb so it will take a while before it needs to be overhauled again. The MPG however, may not be the same as before. Since it's an old engine and engines tend to consume more fuel proportional to its age (according to my mech engineering undergrad brother), the MPG may be more by a bit and it is also affected by the engine overhaul, because of a lot machining and making things larger by a bit, the engine will increase cc (I think) by an amount that will also affect your MPG.\012
\012There..I hope this helps..Good luck! I love these old carbureted engines, they're so simple to tinker with. \012
\012If you're from the Philippines, the man to look for is Mang Vising in Bgy. Bankal, Makati. Just near the INC church there in Evangelsita. Coming from EDSA, turn right just before you reach the INC church and just ask around.\012
\012God bless!
