Spoon B series motor specs
Following are the specs for the "infamous" Spoon B series motor as queried by the masses.
Here are the details of the Spoon "engine" / longblock once again:
- it is a new 98 spec R longblock
- internal components are JDM OE Honda with the following exceptions
- it is fully balanced and blueprinted
- it uses the Spoon 2 piece headgasket for a compression ratio of 11.3:1
- it uses the Spoon oil pump which is stronger and more effective than the OE Honda one
- it should put out around 180hp at the wheel
what is 'balanced and blueprinted by Spoon'?
- all engine components are weighed to 0.01grams precision
- engine components such as pistons and rods are balanced, they all weigh within 0.01gram of each other
- Spoon is able to balance these components because they order/weigh/sort hundreds of pistons, rods, etc. from Honda and sort them into balanced sets
- bolts are torqued within 0.01N/M of Honda specs
- what does balancing and blueprinting do? it makes the engine run incredibly smooth, reduces power lost to inefficiency, power delivery is extremely smooth, power is higher across the entire rpm band compared to a Honda assembled engine, engine/throttle response is much better, the engine revs smoother/faster and is able to withstand high rpm better, engine life is improved considerably especially in race environments
why does Spoon offer this engine?
- Spoon's core philosophy is in balance: good power, good driving feel, and long life. this engine offers all
- circuit racing requirements differ from drag racing: an engine with the aforementioned characteristics is preferred in circuit racing over a high power, less reliable engine which might be favored in drag racing
- these engines are frequently bought by pro race teams competing according to FIA Group N regulations which require stock internal motors. hence they need an engine which has maximum effectiveness and efficiency using stock parts
who should consider a Spoon engine?
- pro/amateur racers requiring a motor in stock trim (FIA Group N)
- circuit racers/enthusiasts who want an optimized stock motor for circuit use
- people who want a new stock or reliable motor with decent power
who shouldn't consider a Spoon engine?
- drag racers
- people on tight budget or DIY
- people who want a high power setup, N/A or Turbo
- people who don't care about or aren't sensitive to subjective intangibles such as driving feel or engine response
what is the price of a Spoon engine or block?
- it is priced comparably to the price of a new b18c5 longblock/shortblock from Acura considering the work Spoon has put into it
- remember it is a NEW longblock/shortblock
- price fluctuates with supply and demand, although spoon engines aren't common here, remember that they are very common and popular in Japan and Asia
- expect price to increase over time as the supply of b18c components dwindles
- contact an authorized Spoon dealer such as IPS, R&D, A&J for a price quote
does/why doesn't Spoon offer a high power engine?
- again, Spoon's philosophy is balance. to Spoon, high power is only worthwhile if the engine can endure the stress of a 24 hour race. to Spoon, a street tuned engine needs to be comfortable and reliable while delivering improved power and driving feel
- Spoon has built and sold high power engines with 200+whp... high compression kits and stroker kits including a 2L kit for the 18C. However, the reliability and engine life of these engines still aren't good enough for Spoon's standards and hence Spoon does not offer them anymore
- Spoon doesn't drag race
