should get all 3 or just the crank pully? what does the other two do?
also, if i am only doing the crank one should get the UR/KJR?

thx in advance

 

My vote goes with the UR crank only(unless you are going for looks as well).Mine should be sitting at SGP waiting for them to get back from SEMA

 

the other pullies weigh nearly the same as the stock ones so its almost pointless. stock pully weighs like 6 pounds UR pully is little over 1 pound.IMO the kit is pointless, just get the one UR pully. get the UR because it weighs less and thats pretty much the whole purpose of getting one in the first place.

 

+1

 

alright, thx for all the advices..

 

Guys,i have a question re:UR crank pulley-i was suppose to have it install last week,
'till i talk to a guy from camp1320 in chatsworth,cali.That,i should never attempt to install the said pulley(unless,my engine are heavilly modded.Otherwise,it break my car in no time.I told him that i have a 2003 g35sedan with fujitsubo exhaust system(from y-pipe/mid-pipe/end exhaust).Plus,i have a Z tube/stillen hi-flow.Lastly the jet hot coated DC headers.He mentioned that i must rebuild my engine internals.
Now,i know that by doing the "engine internal will cost me a serious amount of money.
right now im pretty confuse if i should go ahead install the pulley or suffer the consequence that he said.Pls,advice.(i bought this brand new for$210 thinking that for that kind of money i will gain @ least 5BHP.Or sell it here for less than i paid for or go ebay.I love cars.Especially this one.But,if i will put a POS,i'd rather sell it .

 

I'm no expert on underdrive pullies,and appearently niether is this guy.I wish there was a mute button to push when someone starts talkin sh*t like this.What he told you is false,a properly installed underdrive pully that has been balanced will be fine.Please install the pully and forget what that guy told you.

 

In english? Install a good pulley and you will be fine. Who is the knucklehead that told you otherwise?

 

the crank pulley is where the gains come from. The other two pullies, while they are a tad lighter than stock, basically look pretty - so its up the to buyer

tell the guy from camp1320 it is time to find a new career, or at least do some research before making false blanket statements

 

Thank,u so much for all ur response.I,really appreciate it.Now,i have a little peace of mind.BTW,guys do u know anyone in the SFV / los angeles who is good in installing this pulleys for a reasonable price?Thnx,again for all ur input.

 

UR pulley is a DIY install...you can probably do it during your lunch break.
All your gonna need is a short 19mm socket wrench and a10 mm to adjust the belts.
you don't need a puller to remove the stock. good luck. enjoy your pulley.
one of the best mods for the money.

 

The thing is,im not a technical/mechanical inclined person.Thats why im asking anyone who has godgiven talent or a place in los angeles who can do it for me.
