Engine swap

looking back now i don't think i ever mentioned much about the engine swap so i am going to give you guys a quick look about it.

the above is the original  G4EK also know as the Hyundai Alpha engine its specs are as followed curtsey Wikipedia.

The G4EK is a 1.5 L engine, with a bore and stroke of 75.5 mm and 83.5 mm, respectively. The SOHC 12 valves 1.5 S generated a respectable but not notable 92 HP (69 kW) at 5500 rpm and 97 lb·ft (132 N·m) at 4000 rpm, 

the above is the engine that replace the original one. this is the Nissan GA15DE locally know as the "B14 engine" its specs are as followed.

The GA15DE is an 1.5 litre (1,497 cc) engine with DOHC and throttle-body electronic fuel injection. Bore and stroke are 73.6 mm (2.90 in) and 88 mm (3.5 in). It produces 104 hp (78 kW) at 6,000 rpm and 135 N·m (100 ft·lbf) at 4,000 rpm.

This engine swap nearly made me give up on the project.sadly as much as i prefer to do things my self, the car engine was an area that i preferred not to touch. to get the job done, a certain Arima based mechanic was chosen (name with held for reasons). The original plan was to repair the original engine since i had a second engine of similar built, and the transmission in the car was still good. however the mechanic advised me to change to the B14 engine, which really and truly made since due to its popularity and good supply of parts. so i decided to change the engine instead.

it cost me about $11,000 to change which included labour, B14 engine, brake repairs, transmission and the cleaning of the gas tank. this did not bother me as i had the cash plus, i planned to sell the old engine and transmission to pay for the car. however after the job was completed and i returned for the car. the mechanic claimed he threw away the old engine. now i don't know about you but one the engine was relatively good and just needed parts from the other one to work properly. plus the transmission was good. so why would you throw them away. plus a number of small items in the car was missing.(strike one!)

however since i did not record the old engine numbers and had no way of proving otherwise, i could not raise much of an argument. so i decide to let it go. after driving home, i realized that the car had a strong smell of gas in it. after deciding to investigate. i decide to look under the hood. only to find a hole in the fuel return line, causing gas to be sprayed over the hot engine. (Strike two!) i repaired this myself.

a simple explanation for the fuel return line as explained by an on-line forum member: Fuel injection systems rely upon a high pressure pump to provide well timed high pressure fuel pulses to activate the injector and spray fuel into the cylinder. If any air bubbles find their way to the high pressure side of the fuel injection system it unlike fuel can compress and throw the fuelinjection timing off. So a small amount of fuel is allowed to flow past the injectors and IP and return to the fuel tank carrying any air bubbles that may find their way there back to the tank. This is referred to as a full return (to tank circuit).

last but not least the brakes were still giving trouble, the car was filled with dirty engine oil, the engine was not tuned and the transmission was leaking fluid. (strike! three your out)

at this point i was tired fed-up and actually placed the car up for sale, until someone gave me some advice on how to complete my project. and this is why i wont recommend the same mechanic to anyone
