Video Overview:
OK, so it's been awhile since we've released anything on this "Unassembled" long block build. Almost immediately after this engine was finished, Sam got started on the 2234cc EMPI Engine Battle Build which was a whole fiasco from the hurried schedule, to the engine injecting a nut and punching a whole in a piston. Follow that with the tear down and the current rebuild....but we're getting away from the point of why we're here. We actually had the idea of doing an aftermarket engine tin video back in early 2020, but just never got around to it, until now! Well, then...but the footage has been sitting awaiting other projects.
So, here we are, or were anyway, beginning the completion of the EMPI Unassembled 1600cc Long Block Engine. Sam covers the process of test fitting all of the aftermarket engine tin, and the massaging (OK...hammering, cutting, grinding, trimming) that are needed to get the tin to fit tightly. A lot of additional work is needed on the fan shroud which is above what would be required on an original case since the "Unassembled" long block kit comes with an aluminum case which is thicker than the original magnesium unit.
Fan shroud aside, almost every piece of tin short of the doghouse exit tin will need some sort of work to get fit properly. The more original tin you have in place, the less work you'll have to do. Unfortunately, that is just the nature of aftermarket parts, there is a reason why most shops will pre-build their projects before body work, paint and final assembly. So this is why Sam installs all of the engine tin before mounting other engine components. Almost every piece of tin that gets installed, is pulled off for additional work. Often times, multiple times, and even once one piece is fit, more work will be needed once the next piece is installed.
By the end, Sam has most every piece (there are some pieces of tin that can't be bolted up to an engine on the stand) modified and fit, well. More importantly he covers the processes that will enable you to get your engine tin fit in place to your engine. Most importantly, is to get these steps done before your engine tin is painted, powder coated, chromed, etc. Get the tin fit properly first, then you can work on making it pretty! We can't tell you the number of comments we got when we first finished the assembly of the 1800cc stroker engine Sam built for his Super Beetle way back in 2019/2020. People were shocked and couldn't believe that we would fully assemble and run the engine with "unpainted" engine tin. That engine was later disassembled down to the long block and all of the engine tin was painted to match the car.
With all that being said, or typed....follow along, enjoy and see that aftermarket tin can fit well, just not as well as German, but it will do the job! Oh, and that fan shroud that Sam spent so much time fitting? It, the alternator, and fan are the same ones that got destroyed when the fan came apart at 7800 rpm on the dyno on the 2234cc EMPI Engine Battle Engine.
