boost or fuel..

[ATLDSM96]

i was wondering what most of yall would do in this situation. i bought a E316g a week ago. i can either buy an install kit and put it on tomorrow. or i can get new injectors and fuel pump and put those in tomorrow and wait to put the turbo in? so im asking should i put the turbo on now and get the fuel mods next week, or fuel upgrades now turbo in a week?

What size fuel pump? Anything over a 190 and you'll need an Adjustable Fuel Pressure Regulator. You'll also need some sort of tuning device to control your new injectors. Why don't you just wait the week and do it all at once?

If you just install the turbo, you'll have to run low boost, making sure not to max out your stock injectors and pump.. Hope this helps.

+1 to what he said. wait to put the turbo on until you have the proper fuel mods. and i wouldnt put the fuel stuff in until you can put the turbo on other wise you would have to tune the car twice as it would run rich with the new fuel mods on a stock setup.

Don't do anything without logger. I hope you already have one.

 

[ATLDSM96]

i plan on getting a logger, but dont have one yet? but i wouldnt know what any of the logs meant because i have never tuned.

 

[turboking15]

start researching. the search button is your friend. any question i have ever had i have been able to find at least a couple threads on it with the answer im looking for.

You can't run larger injectors without tuning. There's no need for a larger turbo, unless you can tune for higher boost.

Like everyone else stated...

NO fuel mods until you can tune and log. NO turbo until you get the fuel mods.

I've never had a problem with my stock FPR and 255hp, maybe luck of the draw?

If you want to blow up your motor then go ahead and put on the turbo without fuel and some way to tune that increased fuel. I can't understant the impatience that so many people have to blow up their motors. It's not like just slapping on a bigger turbo will make more power without tuning for the increased airflow. The stock ecu and fuel system can only comensate for so much and then boom.

Stock Injectors will work fine for now as long as you're running stock boost. I'd put in that fuel pump though and then put in the turbo. If the Fuel Pump is bigger than a 190, you're going to need a FPR. Just run stock boost, and as soon as you have something to tune it with, you can put in those injectors.

I was in the same situation and I put the turbo on first and believe me its a easy way to mess up you motor without the fuel upgrades first

 

[ATLDSM96]

so if i left the boost the same it would be fine, until i got a logger, fuel pump and injectors? i ask because i have a few days off work and have a chance to put it on now, and i usually work alot and wouldnt normally have time to put it in.

 

[DSMsOwnYourV8]

And a wideband or S-afc. If you have a chance to put it in now, go for it. Just don't drive it until you have the supporting mods

 

[marcelo_caz]

doesnt really metter, you are getting both anyway
=p
I would go for the turbo first.

You can do the fuel pump, AFPR, and turbo all at once as long as you get a logger and are able to keep the boost down to stock levels. You can NOT do the injectors until you have some sort of fuel controller and tuning tool.

After you get the FP, AFPR, and turbo installed, get wideband and fuel controller. Then get injectors.

 

[ATLDSM96]

but is a afpr needed for a 190 walbro

 

[DSMsOwnYourV8]

No a FPR is not needed for a 190.

Technically, yes, practically, maybe not. I'm just going off of what I've read. At low load and low rpm, your fuel pressure will probably be a bit high, and you'll run rich, but as you tromp it and/or go up in rpm, more and more fuel is "leaking" out of the injectors, so the stock FPR doesn't have to flow as much fuel and will stop overrunning. I'd imagine you could start out without the AFPR; many seem to run fine that way, but you should atleast know that it might hurt a bit.

Get some fuel, and a logger before you turn the boost up. Try to keep it down.

You woud probably be fine. But, do you have a reliable boost gauge? Do you have a boost controller to dial the boost down if your reliable gauge shows more boost than stock. I'm not sure what the wastegate presure is for an evo3 16g, but I would not take a chance without a logger or at LEAST a boost gauge to see whether or not you're flowing too much. . .

Get a logger or S-AFC first. Then do all the fuel and once you have all the previos done move on to the bigger turbo.

This was my path.
1st SAFC
2nd FPR
3rd Pump
4th Injectors
5th Turbo

Problem is that he already has the turbo.
