Sounds like you need a boost gauge(stock gauge sucks, not accurate) and a boost controller. I have Turbo XS but it spikes 2-3 psi. When you put it on, dont go past 15psi on your stock fuel system. Sounds like you need a clutch and a turbo after that. How high horsepower are you going to? Best thing to do is figure out your goal, and buy whats right.

yea i got a boost gauge and boost cont...the greddy profec....its my daily driver im in college ...i just want somethin that is pretty quick but reliable....what all should i do with fuel..i have read a lot about rewiring the fuel pump???but i dont kno ### thats all about

 

[MrBoxx]

A 190lph fuel pump would suit your needs pretty well. Rewiring is always a good idea. You can find instructions here. After that, you would be all set for a 14b or 16g (at low boost) until you got some larger injectors and something to tune with, via AFC, AEM, DSMLink, PowerFC, Haltech, etc.

A datalogger/pocketlogger is always a good idea.

Dam, he just about summed that up.

### size injectors should i go with an how much increase would i notice from a 14b upgrade

If you still have the stock upper intercooler pipe, you may want to upgrade to a more free-flowing aftermarket pipe. The stock intercooler pipe is pretty restrictive, especially near the 90 degree bend. Just make sure that its flanged for your BOV of course. You may also want to clean your intercooler's interior (free mod) to get rid of any oil that may have accumulated over time. Hope this helps.

We don't talk horsepower numbers and increases here since it's seen as bench racing, however I can tell you that a 14B is a significant step up from a T-25. With a set of 550cc injectors, you can power either a 14B or 16G (small or big variant). If you decide that you want an EVO III, 650's would be a better choice.

If what you're looking for is a fun street turbo that will spool at low RPM's, I would look into either a Small or Big 16G or even a T28 from Forced Performance. The 14B and 16G will require install kits, however the T28 is a direct replacement for the most part. Eric's recommendation about using a 190 is right on and it will power any of the turbos I mentioned without issue.

Well you dont need anything over 550s if your only going with a 14b. It pushes somewheres around 50 cfm more air, so i may be wrong, but with good tuning, about 30 horses easy. Id get another opinion first though.

 

[MrBoxx]

Going from a T25 to a 14b is like the difference between night and day. Well, maybe morning and afternoon. For injector size, it depends on what you get to tune with. If you go cheap with an AFC, 550's would be about the best combination. Plenty of people run very well with a 190/550/(14b-16g)/AFC combination. If you go with something a little more pricey and complex, like DSMLink or AEM, those will compensate for whatever size injector you throw at them. But still, 550's are a good size.

Like Vtecvrsturbo said before, your goals are going to determine what you need to buy.

im really looking to get a decent increase with the lowest cost but all this is starting to sound expensive haha...i do appreciate it tho thanks guys

Well...what's more important to you...straight-line or twisties? I love going through the corners. It dosn't matter how much power you're laying down. If you don't fix the suspension system you'll plow right off the road going into a corner hot. You have the basics. I'd say your next perchase should be some sort of engine managment system. DSMLink should do just fine. If you decide to upgrade beyond the capabilities of the AFC you're covered. After that...invest in either a set of Koni's with good springs or if you have the money...JIC or TEIN coilovers. Don't forget anti-sway bars and strut tower braces. For crying out loud...just stiffin up the rear end. I spent all my money on power and now I can't stand how my car just want's to fly off of the road mid-corner. If you're all about smoking the straight line...ummm. Upgrade your fuel system (Aeromotive all the way) with an EMS of some sort then throw some NOZZZZZ at it. Just make sure you tune it right. Nitrous Oxide will NOT damage your engine any more than increasing boost pressure would as long as your sh!t's tuned right. Good luck!!!

I want to upgrade from my Walbro 255 B.S. fuel system to the Aeromotive A-1000 EFI system. I have a Big 16G with supporting mods. I use DSMLink to keep things in check. With some big injectors and a 120 shot from NOS's Pro Shot Fogger Kit and Snow's MAF-T Methanol Injection Kit I should be pushing around 450-500 awhp on high boost. Yah yah...I know...I'll eat turbo's like no bodys business but spool up's gona be insane.
