Here are some facts.
Parts that remained same among the years.
10103-1N555 partcode:10103 Complete block
11000-1N510 partcode:11010 plain block (using a newer fast you get 11000-1N550 as the latest part which is a standard B14/N15 SR16VE block)
11040-1N520 partcode:11041 plain head (no cams,valvetrain)
Parts that have upgraded part numbers are among others: pistons,rings,flywheel,solenoids,Slack chain guide,rocker arms&shafts,water pump
There are two basic part numbers for complete engines. Engine comes complete without manifolds and sensors.
10102-1N557 partcode:10102 Bare Engine 2WD.PUL.SR16VE.N1 9811-9910 (VersionII)
10102-1N555 partcode:10102 Bare Engine SR16VE.N1.MT 9709-9910 (VersionI)
In the past years there were also rebuilt engines but now you can get only new. I had seen
this guy and made me wonder how he manage to get a brand new N1 engine. Well he did!
What to know how much I was quoted about the 10102-1N557 engine? 489900Yen!
People who look for a N1, there's hope out there...
My vin and every VersionI vin I tested displays 10102-1N555 for the engine including all Version II Lucinos (I have 7 so far) but in all Version II Pulsars you also get the 10102-1N557 engine as an option to choose. Fast has the same pricing for both.
