I was wondering if you guys can feel the VTEC with the turbo? Because on my friends car, a GSR Turbo, I cannot feel his VTEC at all...

And I'm thinking if I should stay non vtec or VTEC The B20.

 

I really dont like frankenstein motors...its just me. If its a track car then by all means. Whatever it takes to get that little extra power but the daily driver reliability is what i dont trust. You probably dont "feel" the vtec kick in because all you feel is the increase of torque from the turbo.

 

I don't feel it in my GSR turbo. I don't care either .

 

I can't feel mine but I have a D16Z6 and I never could. I used to be able to hear it but now all I hear is the turbo spooling.

 

Yes, defenitly go Vtec for Turbo. Turbo loves Vtec and the turbine can push much more air into the combustion camber than a engine with only one cam lobe. We Vtec turbo junkies are very lucky to have a very weak cam lobe to get the turbo spool up a bit better and than switching to the aggressive lobe for HUGE top end power. Show me an other turboed car which can produce so much hp on low psi like Vtec engines.

 

Ya, definitely the **** for low boost applications . If you plan on boosting a lot might as well just get a B18B.

 

Yeah, I love my turbo Vtec...wait a minute...nevermind...I don't have Vtec on my LS.

 

so let me get this straight (Im doing my research before either head swapping my D16y7 and then turbo or just turbo on my stock motor) Vtec will help the turbo make more power....I thought the flow characteristics(sp) of a head werent that importiant if you were force feeding it. Hmmmm....and if so, how much more power does a sohc vtec make than a regular sohc??

 

I swapped a D16Y8 head onto mine, and I am glad!

If possible though, I would rather build a full D16Y8. Did I mention how this little SOHC screamed at 15 PSI the other day?


Oh yeah...the D16Y7 intake manifold SUCKS. At least replace that POS.

thats right
i love the sound of turboned vtec engine

swissturbo

 

look it this way. When a valve stays longer open and make a higher lift you can force more air into it. A cam with 2 lobes (like Vtec is) uses the 2nd lobe to get the valve sooner open, lift it higher and let it longer open. Especialy the higher open valve is what you want. The long opening time of the valve is a bit bad, but you can adjust this with cam gears. You don't want valve overlap with F/I, valve overlap is only good for n/a.

 

 

Feel it? hrmm..not like an NA VTEC car when it kicks in...
HEAR it....yes, when my VTEC kicks in its almost twice as loud as when I was NA.

 

Whats a turbo?

 

Yeah, what's a turbo and why would you want one when you have a VTACH
