i got a turbo kit i want to put in the ls swap i have so far i just got the turbo kit complete im looking to only boost 5 to 6lbs would i still need to change map sensor or can i bypass it since its on the firewall ,2nd would i need to change the injectors and fuel regulator i was goin to purchase these items but i got a friend who said to get a missing link for the map injectors and regulator and another who says with that low of boost i wouldnt need to either i is fine with me just need input with any one else who has this setup and what they used any info would greatly appreciated i love the ls swap but i have the turbo sitting thanks ht dudes

 

what up.... jus get a fuel pressure regulator...u really dont need anything else if ur gonna stay @ that low of boost... if u have the money go ahead and buy injectors and a apexi safc ...and you'll be straight mabey throw a walbro fuel pump in to...believe me 5lbs of boost is gonna get old fast and ur gonna want more...hahaha so if you have the money get what i suggested

 

Thanks dude wil do, also with that low of boost would I also need to take it to get tuned as well

 

Do not listen to this guy. You will have a most unreliable POS. Anyone that posts "hahaha" in a post and tells you to use a SAFC tends to not know what they are talking about.

Go research in the Forced Induction forum and find out what everyone else is running. The stock regulator and map sensor should be left alone. Get bigger injectors, Walbro and get an ECU and a good tune.

 

So i should just leave the map n regulator alone get a fuel pump injectors and tune my ecu than? Keep in mind im only going to boost around 5 lbs

 

Always get it tuned. On a dyno if you can or street tuned if you have to but get it tuned. And you keep saying 5lbs. 5 lbs on what? 5lbs on one turbo is not the same as 5lbs on another.

Again. Checked the FI forum. I'm sure you aren't the only person on the planet running a boosted LS.

 

^ X2. That apexi setup alone will cost more than if you just got a chipped p28 from phearable and get it tuned by a pro.

 

doesnt matter if your running low boost you always should get it tuned so it runs right and is more reliable...

 

So get it tuned cool but its a stock ls n im running a pr4 and its a t3/4 turbo

 

And you shouldn't have to worry about a map sensor yet. Stock map sensor, correct me if I'm wrong, is a 1 bar which means it can record up to 10.9 pounds of boost.

 

Correct.

 

This.

 

1 bar equals 14.7 psi, but you are correct that the stock map sensor can read up to 10.9 psi
