turbo and i'll never go back

 

 

And the LS motor is more ready for turbo than the Vtec Motors...
Just like the Vtec Motors are more ready for Revving than the Non-Vtec Motors...

Did you read his post?

He asked for turbo LS or LSVtec, not Internals and Engine Management and Sleeves...

 

I was just pointing out that it isn't made for Vtec OR FI.

Vito_Corleone

 

And your point for pointing that out is?

 

turbo ls w/ good fuel management....

8psi will yield around 220-230whp and will be very realiable and will last quite a long time

 

I gues my point was that the way you worded your answer seemed a little argueable, as you could say the same thing about either answer.

 

Well heres the arguement...

Compression on a 98 LS is what? 9.2:1...

Compression on a 98LS with a b16a/b18c5 head is what? 9.6:1; with a b18c1 head 9.7:1...

9.2:1 is favorable for FI on stock Cast Pistons...

Now, turbocharging an LS with say a T3/t04b 50trim stage3 turbine in a .48A/R turbine housing will make 15psi at around 4,200rpm and take it to redline at 7,000rpm with lots of torque from 2,000rpm to redline...Great Street Power...

Now with LSVtec, you have a head that is meant to redline at say 8,500rpm and a bottom end that is meant to redline at say 7,000rpm...Combine the 2 and you have a motor that no engineer will design as it sits...You will first want more compression and upgraded rodbolts to make reliable power...
Now that power is not nearly gonna come close to 5psi on a turbo LS and its not gonna be as reliable either...

So, you use the strengths of the motor...ie, lower compression, low RPM torque...

Instead of abusing the block with high RPM...

 

good point

 

I agree with everything you said. I was never arguing that the Ls/Vtec was, by any means, a better choice, just that the initial wording of your respone was a little confusing.
