vortech FAQ: read this before asking vortech questions
whats up guys, Im ordering a vortech kit with the v3 blower as soon as I get a couple questions figured out. I have and 06' rev up and would like to get the cog pulley that makes more boost. For a revup do you still get the 2.87 cog or is the pulley different that the non revup. Also does the different size pulley require a different size belt than the one that comes with the revup kit or do you just use tensioner. sorry if the my question had already been answered a lot of the information I have read has been for the non-revup.
The 2.87 pulley is a serpentine pulley ,this is different from the cog pulley.In order to find the correct size you need to click on 6 rib pulleys on there site.This is the pulley on the front of the bracket that all 350z's use.
The cog pulleys are the ones on the back non rev up uses 28 for supercharger pulley and 32 for jack shaft pulley.On the rev up if I am not mistake it's 30 for the supercharger and 32 for the jack shaft
Hope this helps.
^another tip, the belt that works on 3.33" will work on 3.12". smaller pulley will require shorter belt. and make sure u always carry a spare.

I have a revup Vortech kit and I have the belt that I used when I was running the 2.87 pulley...I've switched to an even smaller belt because I'm now using a 2.75 pulley, so I can sell you my brand new spare 2.87 belt if you're interested...
Hey guys. I've been searching but it is hard to find. What adjustments would be needed to install a Z kit onto a G? On the first page it says some pipe fabrication but does anyone know what exactly? Sorry if it's on page 33 or something of this thread but I only read to page 5 or so

Hey guys, ill be installing my transmission oil temp gauge in the next few days. I was wondering if it was necessary to tap into the oil pan, or could I just tee off of the line before the trans cooler?
the oil pan is not the same fluid as the transmission.
if you mean oil, then yes you can get it from a pan spacer, if transmission, then yes you have to T into the lines goin to the cooler.

as long as the engine is a non-rev and the kit is a non-rev or the kit is a revup and the engine is a revup then it will work fine.
Mine was a "350z" kit per se and it went right on. The instruction manual even lists both cars and shows pictures of both cars.
Hey guys, my boost gauage read 16 at idle, is that normal? I only hit 5 psi at 55k, is it because of the blower or the bypass valve? I recently play with the threads and I don't know if my blower is getting bad or not, I heard a very loud cracking noise at idle. I am running 2.87 on a non rev and I have half inch spacer, HFC, headers and true dual exhaust. Please help!!

fyi all my car has been through hell n back since no ember 1st when I got into a multi car pile up.
good news is. 430rwhp dyno dynamic at 12psi 6500rpms. 460rwhp at 7500rpms. im finally built at 8.8 compression. installing new 2..62 pulley as u read this. weird misfire at 6900 rpms so might back it back down to stock rev up rev limit. troublshooting plugs,coil, senors, etc . but hills garage leaning on too much pressure on vavles at higher rpms.
I also switched jobs twice since november so ive been not posting much just reading.lol
before was 411/365 @ 14 psi. stock compression.
now is 440ish/350 @ 12 psi w 8.8 compression.
do not apples to apples but way more power w less boost/comptession.
also raised revlimiter due to built block thats where 460rwhp came from

Does anybody have dyno charts with a Vortech, before and after running a Cosworth plenum? Any input would be great on running them together.
Update - Just found this quote from Binder, but it's all I've seen.

i modified a generic a pillar.
system setup looks good. I wouldn't worry much about the cosworth. For the gains you'll get it isn't worth the cost.
why aren't you running the 2.87 pulley? depending the dyno you might need to go to a 2.87 to get 400hp.
400hp is plenty safe on that engine because it won't have near the torque that a 400hp turbo setup would have. Torque is the issue. If it's properly tuned 400hp (which will be low/mid 300's tq) would be perfectly find for that engine. The only problems you would encounter is if the tune sucks.

it pulls vacuum at idle. google videos of vortechs to see if cracking noise is normal. it seems your blower is just fine.

good to hear it's up and going. Let me know if you're coming back over here anytime soon.
Too much pressure on the valves? that's a bunch of crap. 8.8 comp ratio with 14psi isn't much pressure. Sounds like spark blowout. Usually at high rpm when the boost is up there the ignition system isn't strong enough. check the plug gap. I would say set it at least down to 30 thousandths.
If i remember correctly this is a DE engine. If you didn't upgrade the valve springs or anything in the heads then i would be a little cautious about running 7500 rpm. I know a few members get away with 7000/7100 but getting to 7500 is risking some valve float with the soft, crappy stock valve springs. That smaller pulley will increase that boost and maybe look into the 928 impeller since it's stronger and won't fly apart like the oem vortech cast unit. That will get the boost up without having to over rev those stock valvesprings.
If you are buying it just for looks in the engine bay then kudos. Buying it for an increase in power then you are spending way too much for the amount you will get back. I'd do cams/headers and even head porting before worrying about a cosworth.

I have a revup built 8.8 comp T Trim but i hear i do not have race bearings in blower because i upgraded my S blower to T. Next bearing swap ill ask to upgrade since im spinning her hard. Sept 12 i have appt for Final Tune! Shooting for 500 at around 17 psi!. No belt slippage yet, thank you rev up motor n kit!
