Exhaust, fuel pump, boost gauge, boost controller come to mind first.

Follow the upgrade path. It is proven to work!

Boost gague
Some kind.of tuning software

There is a section at the top of the home page called upgrade paths you should follow that. Always search before posting or people wont answer or yell at you. Anyways you need a way to tune it because i know your running hella rich with noway to controll those 550s.

 

[thomcasey]

At least a 2G MAF, that will help with the richness a bunch.

+1 good luck

Upgrade path its all there. depends on a lot of things your goals too.

 

[BoostedBeaver]

Listen to all the other post and check the upgrade path, but you need to have an Idea of a power goal for your car. Choose something realistic for your circumstance and then start researching the parts you think you might won't. After this you can start to buy parts and maybe have a little understanding on their purpose and reliability. Hope this Helps.

i have a boost gauge and a boost controler and exhaust what size fuel pump ?

 

[92AWDHX40]

You have to read the upgrade path its all there. We dont know much about what you want your funds, or goals. Look there lots of information.

Like Victor said, it depends on your goals and budget. A Walbro 190 or a Walbro 255 and an adjustable fuel pressure regulator (AFPR) are the most common choices. The 255, while the actual pump costs the same, is more expensive because you will need an AFPR to keep from overrunning your stock fuel system at idle and low RPM driving.

 

[92AWDHX40]

You wont need the 255 get a 190 and call it a day.

i want to get around 300-350 on my daily driver will the 190 work for that money dont matter i can work to make more

 

[92AWDHX40]

Have you looked around on the vendors pages.

It is likely that you have more injector than you are actually using. Ultimately the fuel pump needs to be sized according to your maximum horsepower and maximum boost.

Here's the fuel counsumption calculation boiled down:
HP x 0.42 = max fuel consumption rate (in liters per hour)So if your output is 300 HP:
300 x 0.42 = 126 lph

This is pushing it a little close for a Walbro 190 at 20 psi boost.

To plug in your numbers: 350 X 0.42 = 147 lph.

If you check out this comparison by RRE, RRE Instructions, you will see that a 190 lph pump will not support that flow at higher pressures. Don't forget that your fuel pressure rises 1:1 with boost pressure. So even though your base fuel pressure starts out at 37 psi, by 20 psi of boost it's at 57 psi. According to the RRE comparison, at that fuel pressure, the Walbro 190 is only flowing 145 lph.

Here is some more really good info:

Wret is correct ... for a more accurate calculation that factors in Boost Pressure (which translates to fuel pressure due to 1:1 boost to fuel pressure), use these calculations:

http://www.dsmtuners.com/forums/newbie-forum/275824-fuel-injector-question.html#post151334548

A 190 with a rewire on a 2G (at stock base fuel Pressure) at 20 psi flows around 141.3 ltr/hr or enough for 588 cc/min injectors at 80% duty cycle... give or take 10% exactness and interpolation.

A 190 without a rewire on a 2G (at stock base fuel Pressure) at 20 psi flows around 124.5 ltr/hr or enough for 518 cc/min injectors at 80% duty cycle... give or take 10% exactness and interpolation.

This is the max output flow the 190 can give and feed your injectors... irregardless of the injector size.

A 190 with a rewire on a 1G (at stock 1G base fuel pressure) at 20 psi flows around 165.8 ltr/hr or enough for 690 cc/min injectors at 80% duty cycle. Note: injectors are usually rated at 43.5 psi... so when used on a 1G the flow decreases due to lowered based fuel pressure. i.e. 550cc on a 1G = 507 cc on a 2G. Thus the 690 cc/min would require 748 cc injectors on a 1G ... but only flow 690 cc. The resone is the base fuel pressure. By dropping the fuel pressure, the little wally 190 can supply more fuel. However, as you drop the base fuel pressure the injectors actually flow less fuel, so you must compensate with even larger injectors. Though in this case the drop in fuel pressure more than compensates and as you can see with an apples to apples comparison by dropping the fuel pressure from 43.5 to 37 psi the wally 190 can 690 cc/min injectors versus 588 cc/min. Though for the 1G you must run 750 cc/min injectors to get the 690 cc/min flow.
Also note these are the maximum flow rates of the pump and I personally would never push them that close to the edge.

With that as your goal, I would go with the Walbro 255 and an AFPR.

Also check out this whole thread, it has a lot of very good information on this subject. http://www.dsmtuners.com/forums/newbie-forum/277910-880cc-injectors-walbro-190-dsmlink.html

Hope this helps!

You should really start your own thread for this instead of hijacking this one but here is how you do it: http://www.dsmtuners.com/forums/newbie-forum/281518-how-install-turbosmart-tee-style-bleeder-style-mbc.html

just my .02 worth.

he is going to need a lot of things to get this thing to 300whp as that is my goal as well. My mods are the following

255 fuel pump
regulator
greddy mgt
880cc injectors
built engine with 9 to 1 compression
FMIC
boost gauge
pyrometer
afr gauge
small 16g turbo tdo5

i had 550cc injectors but they would max out around 290whp and didnt want to run to close to 100 duty on the injectors so went with larger injectors that were recommended by the tuning shop in case i wanted to go with a larger turbo later on like a gt2871 or gt3071.

it is getting tuned in a couple days and last put down 268 awhp and 269 awtq this past friday.

Hope this gives an idea of what is needed to get the 300 to 350whp he wants. If i missed anything, feel free to add to it.
