Default conversion to Gt

i'm in the process of converting my limited into a gt. i purchased a low mileage turbo and manifold w/ oil lines off a srt-4. i want to know everything i need. so here is a list of what think i need and feel free to let me know anything i'm missinig.

intercooler
tubing to turbo and from throttle (for intercooler)
new fuel pump
new fuel injectors
new pcm
gt upper and lower intake manifold
new fuel rail

also some of these parts are hard to find on the performance side. so would for example and srt-4 performance fuel pump fit in my gas tank. or do i just pick up everything standard for a gt version.

Unless you are only going to run, at the max 8 psi, if wanting to run more boost you are going to have to upgrade the engine internals. The na and turbo engines are not the same strengthwise. The turbo engine is much more stout. A stock GT boosts to 13 psi.

all i'm looking for is alittle pick me up. i'm fine with 8 psi for now. until i get bored with it then i'd look into a new camshaft, connecting rods, pistons and all that. so with 8 psi i'd be around how much hp. i know the gt comes in 180 and 230 hp (04-09). the 03 only had 215hp. because the stage 1 injectors then came stock on the 04

i want to be able to hop on the freeway and get up to speed without my car sounding like go kart.

Actually, it's the turbo lite that comes in at 180 hp. Same engine as the GT, but detuned down to 180 hp and you can use regular gas. You are installing an intercooler and a boost gauge?

the intercooler i heard is a must to have so yes on that part. the boost gauge i am not sure about. i've been told that they aren't stock on the gt because i the small amount of boost they produce. so would i need one for running 8-10 psi?

How will you know what boost you are running? How will you know how close you are to running too much boost? A boost gauge did not come with the GT or turbo lite because Chrysler was too cheap to include one. Your first two gauges should be a boost gauge and a air/fuel gauge so you know if you are running lean or not.

lol i always thought you could set it and forget it. i'm not sure of the gt but the srt 4 turbo has a internal wastegate. so the actuator would be adjustable.

and just what i needed more gauges. i already have three (oil pressure, volts, vaccum). no if i were to run lean how would i fix it. would i need a laptop and all that jazz, lol. i am not trying to be all fast and the furious!!!

I had a '03 GT and have a '05 SRT-4. Both have the same wastegate and neither can adjust boost.

To fix a lean condition you'd have to have an aftermarket fuel pump, a return line and a way to add fuel. You could get a boost/vacuum gauge and replace the vacuum gauge. You could do the boost and a/f on a dyno when you tune and forget about the gauges if you don't plan on playing with the boost and just leave everything where it is when you tuned.

you would be better off selling the limmited and saving all your time, money, etc and buy a used GT. You will still be left with a huge debt and a limmited. You will not have the GT suspension, interior, engine, tranny, wheels, tires, etc....Just get a Turbo GT used...You'll be further ahead in the end
