Ok so for starters I have a stock Ls turbo efheres wat I have

Stock Ls motor and trans

2.5 charge pipe and the rest I's 2"

450 dsm injector

Walboro 255 fuel pump

Inline pro cast iron manni with 2.5 dp and exhaust mandereal bent

Drag intercooler

S100 ecu

I made 270whp and 230tq I'm shooting for 300's what would I have to do? In other words a budget build please chime in with diff ideas. My other option was to but another fresh Ls motor do ard head studs and boot it to 300hp and blox intake manni idk lmk wat u guys think I have a kid comin in 2 mnths so can't slurge

 

quick easy would be more boost!!!! it should hold it if you just want 300 hp

 

Ok thats wat I'm thinken I jus dnt know how reliable I'm getting a jdm long block fir that for 600 good idea or I rarely drive the car

 

Will 300 be safe

 

3" downpipe and an intake manifold should put you right there. That is if you're willing to spend money. Also will have to up the boost a few psi. If not just turn up the boost as much as needed to reach your goal. This assuming your turbo will support it. Arp head studs are something that should be done no matter what. Just a nice precaution. As for safe..Well there are plenty of people making 300 on a stock ls. A good tune is a must.

 

there are some pretty powerful ls/vtec on stock blocks which is still a stock ls bottom end

 

Ya I wanna keep it straight Ls and eventually build

 

Ok Im gonna buy a blox intake manni should I use stock throttle body or upgrade and as for turbo I have a turbonetics t3t4oe 60 trim

 

Helll, you don't need a new Intake manifold to make 300, but you will need better injectors and tune to do it. You can get 300 without any need for an IM.

 

i agree with him... better injectors and tune it and u can get to that 300 easy

 

Ok koo wat injectors u guys recomend I have dsm 450cc now

 

Yes it's not 100% needed but it will let you achieve more whp very easily. Not a bad upgrade considering you can pick them up used for $80-100.

 

I thought the heads breathing was bad so instead of internal work I was gonna atleast put a manni on it

 

More like only 10% needed. With better injectors and a better tune you can beat the need for that Intake manifold. Its almost like you're assuming that the air is being scavanged as opposed to being forced into the combustion chamber.

More power very easily is acheived with a $80-$100 boost controller.

 

I have a turbonetics mbc now

 

Ok so basically debating on the I m but wat about 2.5 dp to 2.5 mandereal bent exhaust to bibrant 3" inlet and outlet muffler will that be ok for my goal I know it'll be better to go 3" but this place by me wants a lil over 600 for the set up so. Lmk thanks for all the info and advice h-t

 

your injectors are already limited. no matter what you do you wont have enough fuel to feed the motor.

 

Why exactly would you need a new intake manifold? An aftermarket intake manifold on a stock LS motor with a turbo is not going to allow you to "achieve more whp very easily". LOL

 

TheShodan is correct. If you want 300 all you need is bigger injectors and turn the boost up. Anything else is wasting money to get you to your goal. Torque may hang in there a little longer with a different manifold but not needed for 300.

 

You're still not getting it. These items make even more efficient power after you get larger injectors and a better tune. That is a better use of your limited time and resources until the baby arrives. You can always add the exhaust later, and a tune will not be needed. (Luckily you're not a subaru)

 

Injectors retune more psi.... Winning!!!

 

Alright injectors and retune it I's thanks guys
