Default Stage-4 Install

Just for future reference, about how much work is involved when upgrading to stage-4 (VF34, injectors, fuel pump)?

How much time is needed?

And at what level of difficulty would you rate this job?
1-to-10. Ten being Master Tech, One being drunk Chimpanzee.

My main question is about the fuel system. How hard is it to access the fuel pump, and remove/install the injectors?
I'm a beginner tech with little experience.


thanks.




P.S.- Before I get scolded for posting this in more than one place...I put it in the wrong place the first time, and the "specialist" monkies cried about it.

I would say about a 6-8. Not so much difficulty but you need the patience of a saint. Also if you have never done these before there are a few things you need to know. First off get coolant and oil before you start. You will need these. Next make sure you get sparkplugs. One step colder. Next you will need to make sure when you put the injectors in you put a little all-purpose grease around the O-Ring. Otherwise you will proly break them and leak. Expect to spend a whole Sat and most of a Sunday on it. I made this mistake of starting mine on a Sunday night at 7-8pm and not getting done with the turbo and plugs until 4 in the morning. I hadn't even done the injectors and pump yet. Make sure you talk to people who have done it before and even see if you can buy one dinner if he will come over to supervise or help. Also make sure you have at least one extra car there to do runs to Autozone/Walmart/Meijers.

I was able to do everything but the fuel pump/injectors in 13 hours on one saturday. That was by myself and with plenty of time sitting around trying to figure out what the directions really meant. I could do it in half the time now that i've done it once.

The fuel pump was a 1 hour job. Easy, just took patience.

I gave up on the injectors. Took it to the dealer. I've yet to see instructions online that properly (and fully) explain how to do the installation. Given enough time, I might have been able to figure it out, but I might have been able to totally hose my car too

I watched the mechanic do most of it and it took them about 8 hours of mediocre not rushing work. They charged me for 7 hours, because they weren't rushing. All I can say is I am glad I didn't do those injectors. They had nice hose clamps so I lost little to no coolant and absolutely no oil and they removed the whole hardline. They removed the battery, wiper fluid resevoir, the airbox, the coolant container on the top and the oil breather. There are a few bolts that looked like big PITAses to get at (like the one directly behind the oil breather for the green bracket of death). They removed all the gas lines (3 of them I believe) They just plugged the hoses. Me and my friend did the fuel pump and it only took us about an hour and a half. Remove the back seat, make sure you attempt to depressurize the fuel system. I unplugged the fuel pump with the green connector by the ECU and ran the car till it stalled. I also opened the gas cap. Even then when I removed the line with the orange clamp gas came spraying out (about a cup or so). I just soaked up what I could and let the car sit with the door open for 4 hours The stock pump should come out with a little rotation and use the stock strainer. Just use a flathead and apply gentle pressure on the lock washer to pull it up. My fuel pump came with another lock washer, but I used the stock one on top of that. Even running COBB's conservative tune I noticed a more stable feel at higher boost spikes with the fuel pump than without it.

I'd also agree with the 6-8 difficulty. The beauty of installing it all at once is that it actually decreases your time from the sum of the individual installs. Taking the turbo out helps the injector install go faster, and someone else can work on the fuel pump while your doing the injectors. I'd suggest you get on your local forum and see if you can bribe some local members to come over and help or observe. This will also speed things up. Overall the entire install should be less than 6 hours (the total of all 3 individually) give or take considering mechanic ability and urgency of the install.

Good luck.

yeah 6-8...i would definitely say the hardest part are the GBOD during the injector install. its not impossible but it takes a little time to figure out the right angle to get to all the nuts holding the brackets down. turbo is simple..same with the fuel pump...just make sure u have a variety of wrenches and socket extensions.

The most important info I can bestow upon you is to have the proper tools available! I don't know how many times I've started a job un-prepared, then turned a 30 minute alternator uninstall / install into an hour or more because I cannot find the right socket or wrench. Also, depending on how old your car is I would go ahead and make sure to lube the bolts on the downpipe, and the connection to the turbo with some "PB Blaster" so you don't waste 15 minutes on one bolt only to break a stud or worse.

Take it for what its worth, don't rush it, and leave plenty of time to do the job right the first time.

Specifically, have a 12mm ratcheting wrench (also called a gear wrench). GBOD removal difficulty is overrated, probably by lots of people who didn't have the right tool for the job.

If you're new to it, make sure you have all the right tools. Make sure you got oil, coolant, and lots of patience. The brackets aren't that tough when you got the right tools, but ya gotta be patient if you don't.
I'd give yourself a weekend(pretty much all day Saturday and most of Sunday). Injectors are the worst part, turbo being pretty easy, and fuel pump being in the middle. You should definitely have an extra car in case you gotta run to the store. There's a lot of good advice on this thread(the guys above). If you can get someone else to help you out, do it. It'll save some time for ya. Good luck
