Quick Question since my neighbor who has a Cobalt 2.4L wants to buy my LNF K04 Kit to put on Hes car, will it fit? tkx

 

itll bolt up, just gotta figure out the cooling and oil lines and use an LNF header and DP. and all the other bits and pieces

 

they will also need the coolant pipe that goes across the back and the thermostat housing from the LNF. FYI it is not just a bolt on thing like the LSJ setup is there is a lot of the LNF parts that do not bolt up like the intake manifold and such

 

he didnt specify goin to a Full LNF setup, he can use his IM with custom piping, if he wants too

 

^best way to do it^

 

i'm giong to tell you from experience .. you will not hold boost ... at all lol it'll hold till like 4500 then tank.. granted you'll have full boost at 1800 so that "seems" like it's not too bad .. but considering redline will be at 7k.. it will be a trq monster I'll tell you that.. I put down 360 wtrq and 260 whp on "15" psi ( peak was 15 it was at 7 by redline)

 

how were you controling your wastegate because it opens unabstructed at 7psi what kind of boost controler were you using to make it get to 15psi?

 

I'm using a turbo xs standard boost controller, however I have and HDi electronic boost controller in the mail so I can have in cabin boost control and 2 different boost settings

 

Thanks for the replies guys.

 

NICE! if thats a solonoid boost controler then I bet it will solve the problem of droping to 7 psi because that should not be hapening

 

well i'm on the bnr now.. part of the problem was the turbo is very small.. it couldve been having trouble keeping up .. but yes an electronic Boost controller in theory should make a turbo spool a lil quicker and hold on to boost a bit longer

I think there is another problem you have not figured out yet because the LNF guys are pushing the turbos past 15 psi no problem, I hope I dont have this problem when I put my K04 on. well hopefuly you get that sorted out with your boost controler

 

24psi and holding. im not sure how fast the 2.4L will consume the boost though.

 

AH I was not thinking about the displacement diferance it will be interisting to see how my 2.2 will handle it

 

I'm not on the stock k04 anymore.. and the bnr only looses like 2 psi if anything at all by 7500. LNF has .4 less L of displacement which will greatly contribute to "eating" boost as well as much lower compression. it might not be THAT bad for you but i'm just letting you know that the car will start eating boost lol

 

The K04 is just tapped out for airflow at that displacement. Really need a bigger turbo to make it work properly on a 2.4L.

 

yea it shows it more when I put on the 2871 bnr and it was fine
