.... mainly $$$ issues.

I basically got a killer deal on all this stuff(STS in sig), and I am all out of cash for now. It is bugging the hell out of me just sitting in my room in boxes and I want to get it on my truck like, NOW!

My plan was to run the gt-67 at about 8psi with the intercooler. My problem is that my fuel system is stock, and I need injectors, fuel pump. and I should upgrade the oil pump for the turbo, and I don't have a boost controller.

Basically, I need a whole lot more cash to get what I am wanting out of this stuff(... doesn't that sound familiar).


Well the base STS kit is fit to run 5psi on a completely stock motor, right? So wouldn't I be fine to install the kit and run it at 5psi for the time being? I am obviously going to get the pump and injectors as soon as I get the cash, but I think that this is the route I should take for right now.

what do you guys think? should I put the kit on now and just upgrade like the fuel filter, plugs and get it tuned for now?... or should I wait a little longer and do it all up like I plan on running it?


a few other things to consider is the fact that I need posi and a stall, so running 8+psi isn't neccesarily going to help me out at all until the get this done as well.

 

I would definately NOT put that thing into boost with out at least some 42lb injectors and an inline fuel pump. Is it worth taking the risk of frying some pistons?? Wait and do it right. Power is addictive and having it on there will be too much temptation IMO.
At least wait for the injectors, fuel pump, and boost controller.

 

5psi is ok on the stock fuel system, and with stock tuning. If you have a programer or custom tune i would back the timing to stock. You could run it with the kit at 5psi for as long as it takes to get the right injectors, inline fuel pump, custom tune for the injectors and boost.

I have a question for you. The oil return pump, does it have a brand name on it? Because i am looking for one and STS wont tell me what kind it is and where to get it. There afraid of some "compitition" as they put it. I just want to be able to pump the oil from the turbo on my Blazer back to the pan instead of letting it sit in the turbo and leaking into the charge pipe. That sux and could get messy.

 

ok. so we have two legitimate arguments...

I would most likely get Nelson to tune it at 5psi... there wouldnt be much gain without a tune and and the TM, plus I couldn't even go over 100mph w/o one.



and there is no brand name except for and STS sticker on the oil pump.

 

i say tune it at 5psi like you are thinking because it is made to run at 5psi from factory from what ive read on there website but obviously a tune is mandatory

 

The kit is made to run at 5psi out of the box without any other parts, correct? Then I would install as is. The main reason for doing this (IMO) is all that you will learn in the process of installation and running the stock system. Then, when the time comes to upgrade and you have the money and parts, you will have that much more knowledge on the system.

Again, just MO.

 

Those are some very good valid points. I guess it just comes down to what kind of person you are. I like to get things running as Im going to run them. That leaves me more time to fix the inevitable problems that will arise. What are you doing for tuning? If you are doing your own tuning then that wouldnt be a problem, but if you are paying for it or wanting someone else to do updates, that is going to make it a little more time consuming in the tuning deaprtment as well. I just like to get everything together at once and then deal with problems and the additional costs associated with them.

 

Yes, of course it all comes down to personal preference. Do you want to be done, or do you want to be messing with it? Personally I thought I was of the latter type, but I do seem to not be able to leave well enought alone....

 

Well being the type of person that I am, and I like to DO IT RIGHT the first time, I would usually install everything that I was planning on at the same time, tune it, and then leave it be.

But, on the other hand, the reason of consideration is me wanting to run more boost to get more power.... afterall, it IS a turbo and the boost can be turned up easily to achieve this.

The reason why I brought this up is because the way my truck is and the parts that I have so far, it seems practical to run it at 5psi like the base kit with the addition of a FMIC.... so basically, like I said above, I need ALOT more money and parts to run the kit at higher boost.

.... in the end I have to weigh my options:

Would you honestly rather have a STS turboed truck at 5psi with posi and a stall running much quicker times?

or

Would you rather have a STS turboed truck at 9psi w/ peg leg rear, no stall, running pointless high amounts of boost and not running even close to the 5 psi setup???



I think I have weighed out my options, and I think I am going to put the kit on with the parts I have now, get the rear end squared away with an Eaton unit and possibly add a Trailblazer stall(which should work perfect with this setup and my street tires). After that is said and done, I can get the fuel system and boost controller and all that to run it at high boost... That being said, I don't even know what it's going to be like at 5psi anyways, so I might as well try it out and go from there.

 

i would invest in logging software such as efi live before i put any FI on anything.. be it 5 psi or 18 psi, if u have edit id probably pull more timing than stokc to be safe... the thing about doing FI with out the the proper parts is your constatly paranoid and in SAFE MODE always detuning to be safe. things only start to get fun when your watching how things are running and know everything is okay thats when your like **** it, smash on that bitch...
