Great gift for boys

I purchased this for my sons 13th birthday. He was so excited when he opened it. He loves Legos and anything to do with motors so this was right in the middle. Fun for hours! I will mention the description says it's a diesel motor and it's a gasoline motor.

I bought this for my teenage son who loves to work on cars. He loved building it.

A really excellent set

This engine is incredibly fun to build - I think it might be even better than the smaller V8. It's a model of an inline 4 cylinder engine with counterbalanced pistons, 3 valves per cylinder and overhead camshafts.The set comes with outstanding instructions, now almost indistinguishable from Lego. The "four" bags (actually about 12 plastic bags!) enable a very logical assembly. Bag 1 gives the frame and the pistons. Bag 2 builds the cylinders and valves. Bag 3 is all about the overhead camshafts. Bag 4 covers cosmetic finishing touches, including some silver plated pieces.The quality of the pieces is high, although the tolerance/fit isn't quite up to Lego's standard. It's so close, I feel like I'm probably splitting hairs. There are certainly no rough burrs or partially moulded pieces - quality is really high.I've never given a Lego competitor a five star review before, but Lego doesn't make anything like this engine (so it's innovative), the instructions are excellent, and the quality of the pieces is also really extremely good. And the price for 1800 pieces is great. Five stars.
