Has anyone had any trouble with the vortech full kit on a revup motor running no upgraded pulleys or anything?

I got a warning from a shop in Texas that running the full kit was basically guaranteeing me a blown motor and that my fuel injectors would undoubtedly fail resulting in a blown bottom end.

My plan is to run the stock vortech full kit for the revup along with my MD spacer / MREV / Nismo Headers / Nismo Exhaust.

I may later down the line decide to get an oil cooler as a safety precaution.

Does anyone have any info or experience on this?

If you've got the vortech full kit have you guys run a lot of miles on them without problems of blowing your engine?

Thanks for easing my worries or confirming them. Either way I need to know what I'm up against.

 

Dude they probably just dont' want to do it I dont' have the rev up but i knwo lots of people do and the full kit its the SAFEST FI kit for the VQ motor so to answer your question you will be fine with the FULL kit

 

Please don't go to that shop.

 

Its a standard practice done by shops who are looking to make more margin on a sale. Sell you things you dont need, playing on the customers ignorance. You see it on this board everyday

 

If you running the stock injectors with the headers, spacer and exhaust is not really safe. You needed at least 550cc and a utech.

 

Please go to another shop

 

Hmmm....if he's running with the stock pulley, why is it unsafe? Will it lean out?

And please don't go to that shop...

 

we can haz shop nam3?

 

The shop name is Uprev. I never guaranteed a blown motor. I stated that the FMU trickery is not the way to go if you want a reliable car that will last. If anyone wants to argue the merits of a tune vs. FMU we'll get into that.

I explained we would do the work as the instructions detail, but that there is a better way of doing things, and I went on to describe the variables involved in the slap stick junk that comes with pre made kits.

If anyone has a problem with doing forced induction the right way please feel free to contact me.

There is no extra margin involved, he's not buying the kit from us, he already owns it, all he wants is for us to do the the install. We'd rather do the install right than have to rebuild a motor when it goes lean and detonates because boosting fuel pressures to get stock fuel injectors to run enough fuel is not the safe way to go.

 

You draw up the documents saying that you'll pay for the rebuild if he has problems, and at that point I will trust you.

 

Please explain.

 

The Vortech kit has been proven to be reliable. Many people with easily 20k+ miles on the kit without any major issues. Of all the blown motors in FI, Vortech has a minute fraction of that. Most are because of faulty tunes. FMU trickery might not be the most efficient way to get fuel to the car, but it works and is reliable. Even JWT kits use FMU's for their TT's. I've never heard of a FMU failing in 4 years.

You can spend a little more and get a Walboro and 440cc Injectors instead if you don't like the FMU.

Edit: I was suggesting the above for the stock pulley.

 

UTEC, Fuel pump, 440 injectors and a fuel return system is the way to go

 

interesting. shouldn't these modifications cause a decrease in boost by decreasing the difficulty at which air travels through therefore causing, if anything, the engine to run a bit more rich and decrease power? I'm fully aware that if it runs waaaaay too rich then the fuel will swamp out the lubrication abilities of the oil and result in damage but the changes with these mods should be nominal at best correct?

these modifications I've listed make very little changes to the actual dynamics of the car in N/A mode so what is the reason for it being so heavily weighted when under gradual boost as this vortech kit provides?

 

thank you for chiming in. I was intent on getting information from the other users and meant no malice (as is the reason I didn't mention any shop names etc.).

I'm merely curious as to what others have been running and how their duty cycle %, problems, complications etc. they've run into with the full kit.

I do appreciate your candor and the time you spent explaining your logic on why to upgrade fuel injectrs/pump/EMU though.

For the rest of you, this isn't a thread to come in here and insult a certain shop. The idea is to find out if this kit pushes the limits too closely and if it is legitimate to expect a failure due to the various possibilities of adding this full vortech revup kit onto my car.

thanks.

 

My experience has been that all that extra stuff equates to waisted dollars...

plus 1 on UTEC, Walbro and 440 injectors....return...dont know about that but I think running a out of the box kit...with stock stuff like cats and exhaust works...when people change the stock parts..expect leaner A/F etc. The out of the box kit was designed for an out of the box car...no exhaust spacers etc....you have to keep that in mind.

I run HF Cats and a Stillen Y pipe, and APS TB Plenum, but the stock exhaust...then I had the tuner pull the timing back (less HP though) because my A/Fs are 12.0...its a give and take relationship.

so because I pulled timing....I waisted money on those aftermarket parts...why waist the money....leave it stock with the stock kit and the worry factor goes waaaaaaaaaaay down!

 

I still say that you should be more than fine without upgrading the injectors if you are running the full kit and nothing else...otherwise, you would be calling into question the quality and capabilites of the vortech system and Vortech itself...

That being said, I will running 440 injectors and a Walbro, but that's because I am upgrading to a 2.87 pulley....

In the end, whatever makes you sleep better at night in regards to your car's safety....

 

so perhaps it's time to sell some of my mods like the MREV and the spacer and the nismo exhaust? the headers are too much of a pain so yeah, those are staying on.

 

No, you will make power. 4Shizzil, maybe you were running out of fuel and need bigger injectors or fuel pump. If you compared two cars with Vortech, one with the above listed mods and one without, and tuned them to the same AF you should make more power with the one with the extra mods.

 

yeah i wouldnt sell anything....just buy the injectors, UTEC, and fuel pump.

I wanted to stay away from the injectors becaue I know myself and if I went with 550 or 600s i would push the kit to 11psi and then my hand built block from Japan (OEM REPLACEMENT OIL CONSUMPTION) goes boom.

I am sideways in 3rd at 60mph at least twice a day (when i drive it, dont drive to work) so I am happy. I bang the rev limiter very often. I still have the factory clutch....lol. If I start to go more...the mod list expands drastically. I am running 8psi now. I think with a UTEC and bigger injectors running 9 or 10psi might be doable....but again...with the amount of mercy I dont have on my car....I am sure Id blow it.

But dont get me wrong...I bought all these parts when I was NA so they have paid for themselves in smiles and performace. I also run the MREV 2, I forgot about that mod.

plus the APS Tall Boy Plenum is a nice bling factor when you pop the hood.

Id put on what you have...ask a lot of questions on the tune... if you are unsure, you can ALWAYS pull back some timing to decrease the power until you get the money or supporting mods you need to go to the next level as safe as possible.


yes I am out of fuel with the stock injectors, the Vortech comes with an inline fuel pump...not sure of the pressure or type though.... maybe one day I will upgrade....Plus the Unichip does not control the injectors....so upgrading injectors forces me to go UTEC. factory ECU has a limit...not sure if 440 is that limit or not....maybe 380s (anyone know for sure?) but for now with all of these under my belt thus far...I am good. 500HP Viper Convertible inched in 4th, 350W Evo, C6 Auto, Shelby GT500 inched in 4th
why do I need more than that? LOL

total mod build and tunes are under 5K spent for me! I have the HP to $ ratio from hell!
