Hey guys, I have a 05 6mt coupe

I was recently looking into a new car mainly the 335i, but after seeing some FI'd 350z's and g35's the other day, I kind of had a change of heart lol.

I'm completely new to the FI world, and I wanted to ask for help in terms of what parts and costs would go with going FI on a G.

I wanted to go with the vortech s/c kit, but what else will I need with the kit to run "safe?" also, how much should I be looking to spend (a ballpark figure). I'm not looking for crazy power since I have a busa that gets that done for me, but I wanted a good kick from the G so thats how I decided that the vortech was a kit for me.

Thanks!!

Do a search, there's plenty of info floating around. For starters why not check the FAQs located on top of this forum?

 

i have a vortech SC and i keep my car SAFE because its my DD.


heres the basics

-tuner kit
-UTEC
-walbro 255
-injectors (440cc is what i have)
-tranny cooler (becuase i am 5AT)
-oil cooler (you should use one)

 

^^^ Ideally you want most of this. A utec is only really necessary if you only have the unichip. I'm running the vortech FMU and a split second box, so I won't ever need the utec

The vortech kit is in itself a very safe kit for FI. I ran my SC kit on a stock motor with stock injectors and fuel pump, without a tune for over a month and had no problems. The week point with the vortech is the fuel pump. The stock fuel pump even with the votech FMU maxed out does not give the engine enough fuel. You technically do not need injectors at all. The stock injectors flow well enough for most vortech applications. An oil cooler is a good thing to have but not necessary. Another great thing to have that express did not mention is an oil pan spacer

 

very true. however..

i dont have a unichip, but the only reason why i have a utec is becuase i have the tuner kit. it doesnt come with the FMU or any of that, so its necessary.

the reason why i didnt get an oil pan spacer is becuase you dont need one. i tapped my block and its just fine.

i hope you can agree that its not necessary, only unless you dont want to drill a hole into your block.

 

Wow, I didn't know the tuner kit doesn't even come with the FMU. Wow. You don't need an oil pan spacer, but the oil pan spacer makes it so that you don't have to tap the oil pan (easier for SC uninstall), and it allows for an extra quart of oil. I agree it is definitely not necessary, and you can definitely do with out.

 

New full Vortech kits now come with the Unichip. The Unichip pretty much sucks. Why they stopped using the Split Second fmu, I have no clue. But if you are just gonna use the kit out of the box, you should be fine as is. If you are gonna go with the tuner kit, I agree with 705's recommendations. That's a nice basic setup that will get you to the power levels that you want.

 

Great info guys, in regards to injectors, are there any specific brands that you can recommend? Also, I've been reading on the forums that the vortechs do not need the blow off valves, since they're "built-in" or something?

lol sorry for being such a newbie with this stuff :P

 

Deatschwerks injectors are what I would recommend. Vortechs do not use blow off valves. It is actually called a bypass valve. The one that comes with the Vortech SC is a Maxflo bypass valve. Whether you get the full kit or the tuner kit, it will should be included.

 

Jim,

Before you make any move in regards to forced induction, I highly recommend you take atleast 1-2 months of intensive research. Trust me, there's nothing like dropping 10k into a car and then regretting it because you got the wrong kit for your needs/wants.

Seeing how you're not in California, I would probably recommend the JWT 530's. With a good conservative tune, it should be more than fine on the stock block. But this is just one alternative of the many out there.

Goodluck,

-Henry

Great advice Henry. Going FI is not a decision to rush into or to take lightly. You really need to do a lot of research before you make your final decision.

 

I would recommend getting the tuner kit w/ 550cc injectors (at least), utec, walbro & Stage .5 Fuel retrun kit, oil pan spacer to keep the oil cooler(but still tap the block). This should give you a good amount of power and keep you SAFE. Plus will save you money down the road. I bought the full kit over a year ago and since then completly upgraded it.

Good luck

 

if u want "kick" stay away from the vortec, nice power and all but it will not have the kick a turbo will have and if that what you want i would go with turbonetic/aps single/ powerlabs. i recommend single only for price aspect. the aps kit is real complete with fuel system, injectors, etc..
