any updates on engine failures from this kit???
im about to pull the plug on a v3 tuner kit. w/ uprev tuning and injector dynamics 750cc.
stock engine rev up.
spacer/mrev, lightweight (stock sized pulley), headers/hfc/exhaust, jwt flywheel/clutch, koyo rad.
Hoping for some fun times, but the question is, how long does the fun last ????

fmu woes?
Just installed a full vortech kit on my 2004 de, and took a trip to the dyno to see if everything was running correctly a/f wise. As it turns out my car leans out at 5500 and the shop suspects a fuel issue. If the aux fuel pump only comes on when the ss box tells it to, how can I trouble shoot the aux pump to make sure its coming on? Is there a way to trick the car into turning it on so I can verify that it is working without damaging the pump? Also, could a faulty fmu be related to this issue? Wiring wise, everything else is correct. I did search and found mixed opinions.
Aside from this issue everything else on the car runs like stock, it starts right up and cruising around its just like it was before the vortech install. The only engine mods I have is an exhaust and 5/16th plenum spacer. I live in CA and the smog text/inspection is a real problem that is why I went with the full kit instead of a tuner kit with a tune and injectors etc...your thoughts and opinions are appreciated. thanks

Stock INJECTORS are Fine with the Stock Vortech Kit and 3.33 Pulley, But if you upgrade to the 3.12 or 2.87 you will need at least 440cc and recalibrate the FMU to 6/1. The FMU is not the problem as long as you installed it correct.
It could be the Settings in the SS Box, I'd check this first. Should be set to come on about 1 PSI and about 1200 Rpm
It could be a Wiring problem
It could be a Bad SS Box
It could Be a Bad Fuel Pump, test with 12V from battery.
Installing a Walbro Pump is a good Idea. Under $100
DO YOU HAVE ACCESS TO YOUR SS BOX FILE?

I finally got my winter vortech build all done and running.
This thread helped out ALOT! Thanks everyone for all the useful information in here.
I'm not fully tuned yet, just running a conservative basemap on it right now and it's already smoking my 305's above 3 grand in 2nd.

110000 miles on my car. 100k with a Vortech (installed 2004) with 2.87 pulley at 11.5 lbs of boost. Still on stock internals, stock clutch, stock flywheel. Needless to say it isn't a 600 HP monster, but it has 100k miles on an FI daily driver putting down 420+HP on a new motor to the Z world at the time. I couldn't be happier with the results.
The biggest issue I have had with the SC was a rebuild of the blow off valve. Biggest issue with the car - TIRES, lol.

Are you using the full kit or tuner with injectors and EMS etc ?

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.

do you know where to buy the 2.87 kit I checked vortech's website and didn't see it listed. How many rib pulley is it.
