Lightweight crank pulley

**crobaa** · 19-06-2011 07:03 PM

Hi guys, I have a b18c7 with no power steering or air con and would like to fit a single belt pulley as opposed to the current 3 belt pulley. All of the nice billet ones online seem to be 3 belt style. Does anybody make a single belt 'billet' pulley for b18? I've also been researching online and people seem to have issues on the type r motor, something to do with a balancer in the pulley? Is there an aftermarket pulley that includes this also?

Let's all sell our cars and buy houses

.

Back on topic though, apparently aftermarket pulley is ok on b16 but b18 requires balancer otherwise oil pump fails?

just to let you know - honda (i believe) sells a N1 pulley for B series engines. Its just the bare alternator groove thats it. Lightweight....but only for B16a's . There is talk on honda-tech and similar that the reduced weight/harmonics kills B18s and B20s. For the little gain I'd avoid and just use your existing pulley.

I had the first section machined off the stock crank pulley. That did expose the rubber insert that does the harmonic balancer. Ran the car that way for about a year. I then got an aluminium three section underdrive pulley, and had the air con and power steering sections machined off. Light as - under 500 grams.
Car is essentially track only. B18C with various bits, so the lack of harmonic balancing is no longer an important issue for me.

Ok thanks guys, I might give it a miss I wouldn't want to unbalance the motor in any way

Funds are low atm but I'm buying a greddy sandwich plate with built in thermostat for now because I have to get it serviced. That way it will be installed and I'll just purchase lines and 11 row cooler at a later date
