i dont know what to do in a G2 integra. basically, i want to know which would be best for the money. how much money will i spend on both and how much power i will get. im not lookin for crazy power...like 400 hp. im lookin for somethin closer to 270. so basically, my questions are...

1.) how much power will i get from a relatively low boosted LS/Turbo?
2.) how much will i spend on that?

3.) how much power will i get from a naturally aspirated LS/VTEC?
4.) how much will i spend on that?

 

The turbo will create more power and have more flexibility. I think it would be more reliable as well because the LS/VTEC, as cool as it is, wasn't made to work the way it does. It works great if you do it right, but I'd always have that thought in the back of my mind when I'm pushing on it.

how much you will spend on your turbo setup is up to you. there's a million and one options for turbo, FMIC, and fuel management setup combinations available.

You could probably get a T3/T4 for a decent price, find a manifold, get a cheap fmic if you want one and get some piping from JC Whitney and have someone make what you need. You could go with a cheap OEM DSM BOV. You could also use some DSM injectors and go with an FMU setup. The wastegate is up to you too, as well as the boost controller. Manual would be the cheapest, but it's the most inconvenient.

Lots out there man.

 

i agree with WCS on the turbo entirely. LS/VTEC's are becoming a very big trend and for good reason, there awesome combinations. people are doing it all the time and there are even a few that i have seen twin turbod. as far as naturally aspirated goes for one, go for it. 270whp on a naturally aspirated engine would be insane. have it properly machined and i wouldnt skimp on anything. if you have the cash get an individual throttle body setup for NA.

i on the other hand prefer a turbo over NA. you could probably build a turbo kit from 2200 and up.

 

LS Turbo will make more power off the bat. I make 247 whp on mine, the only things that I have upgraded are the clutch/pp, fuel injectors and the fuel pump, everything else is stock. The one thing that the LS/VTEC has going is the superior head design, the LS can feel like it's falling flat on it's face at times.

 

If it's built, it'll hold up just like any other built motor.

Have fun trying to reach 270 naturally aspirated horsepower and keep it street driven. You'd need super high compression and some huge cams. The LS turbo will make more power than the LSVTEC, be more street friendly, and have significantly more torque. What you end up doing depends on what you decide you want, and how much you decide to spend.

 

You're right, like I said, "it works great if you do it right". h:

You just have to... do it right.

 

True story. All the horror stories people hear are those who don't do it right, and try and take a stock LS block to 8400 rpm all day every day.

I need a job and money so I can build my spare block.

h:

 

how much boost did that take?

 

from what i have heard is that a na ls vtec versus a turbo ls that the turbo is not as reliable have that you get somebody that knows what there doing to machine it.

 

you dont have to machine anything to put on a turbo. you will need some maching for an lsvtec. either motor will be as reliable as long as it's built and maintained correctly.
