Nissan OEM Idler Pulley Elimination Kit


This is the OEM Spacer and Shorter OEM Belt Nissan used to eliminate the idler pulley from the later (August 2006+) model VQ35DE Engines. The Spacer is placed in between the engine and the power steering mounting bracket in the space the idler pulley bracket would be normally.

By eliminating the idler pulley you remove almost 1lb of rotating mass from the engine and eliminate a wearing part that will eventually fail anyway. The idler pulley and bracket together weigh almost 3lbs.

This kit comes with ONE Nissan alternator belt and ONE idler spacer.

Choose to add this as a FREE Option to the Z1 350Z / G35 VQ35 Lightweight Crank Pulley.

We also offer several other brands of lightweight pulleys.

Unorthodox Racing Ultra SS Lightened Underdrive Crank Pulley


Unorthodox Racing aluminum crank pulleys on average can provide gains of 5 to 14 HP and 4 to 12 lbs.-ft. on normally aspirated engines and 8 to 18 HP and 8 to 14 lbs.-ft. on forced induction engines. Higher gains are possible. For example, a Nissan 300ZX twin-turbo saw gains as high as 37 HP and 45 lbs-ft. on the dyno just by replacing the stock crank pulley with the Ultra S series lightened underdrive crank pulley.

I had the idler delete as well as the Z1 lightweight crank pulley installed by the guys at Z1. I felt a bit of difference on takeoff. If you're a DIY kinda guy might as well put these two on the next time you change belts or want just a little bit more out of your G.

I'm going to be placing my order for the drive shaft in the next week or two.

 

Intro price or group buy on driveshafts?

 

Here is my review of the Z1 DS.

Car rides smoother

Shifts harder at WOT

Feel more lowend torque (shown on dyno sheet)

Well I have the DS installed for over a week and in that last week

16 dyno pulls (tuning)

over 1k miles

over 20 track runs

After all this abuse still no vibrations or anything abnormal from the DS.

Here is my track times before the DS my 60ft times were consistent 2.1-2.05 after DS 2.05-1.9

White is before the DS ( with a tune for my new headers from RT) yellow is after the DS.



Last night I didn't have one 60ft over 2.1. I was even asked if I was boosted by a guy in a modded MS3 due to being alot faster than the 350z's running. I raced a modded rev-up on DRs and out 60 footed him. I ran 13.4 to his 14.6.

The DS netted me 1-2 tenths in the 1/4 mile.






Dyno before DS at RT Tuning for my new long tube headers vs my old ones



Dyno at Hills garage using the above tune after DS install. I know that these are 2 different type of dynos (dynojet vs dynodyanamics) Look at the lowend between the two. Hill's dyno reads 5-10hp higher than RT tuning or vice versa.

 

Thanks Scott!

Unfortunately not, these have been out for a little while now. Just getting around to listing them on the forums, and already very competitively priced.

Thank you!

 

Bump!

 

How hard is install on the drive shaft ?

 

Just installed my driveshaft over the weekend and its not hard at all. just drop you exhaust and braces and it bolts right up. thanks again Z1 for the fast shipping!

 

Very simple to install, some exhausts require removing the mid section. Other than that, 4x 17mm bolts on the differential flange, and 2 14mm bolts that hold the carrier bearing.

Thank you! Be sure to give us some feedback in this thread after a few weeks!

 

will do! did a new clutch/flywheel install at same time so haven't had a chance to really get on it yet while i break in the new clutch. So far though the car feels a lot lighter...only downside is the chatter created from the lightweight flywheel seems to resonate down the drive shaft making a weird metal churning sound but I guess that is to be expected.

 

Bump!

 

my z1 ds is scheduled for installation this saturday

 

Great! Thank you!
