Hey guys found this cool article on the R18 motor.

http://www.hondatuningmagazine....html

enjoy FG1 owners

 

article was out several months ago.. good read for R18 guys though

 

Wonder how long the serpentine belt and timing chain are rated?

I like the new design - its innovative....

 

Like the article says, how does boost work with a plastic intake manifold?

Also, why does the oval shape of the piston have a negative affect on boost?

i dont know how well the manifold will do with boost but my buddy had an 02 civic and ran a 50 shot of nitrous and he blew his plastic manifold to pieces. might have been a freak accident though.

Unless Honda changed the design of the intake manifold from the 7th gen civic, it should hold up fine to boost. I ran 9 PSI daily on my 2001 civic, and never had a problem. There were others that did blow their intake, but they either had boost spikes or were running too must boost for a stock motor.
