I want to put a LS TB on my y8... what about the difference between IACV and the FITV??..

from my searching that the FITV is on the TB as opposed to a manual d16y8 TB which has the IACV located on the Intake manifold..

would this be a problem running the fitv instead of the iacv??

also any (MAP/TPS) be off??

some people say the LS TB on a Dseries is straight Plug and play..


Please help. Thanks in advance


btw keep the negativity outta here please! thanks again!

 

It's a direct swap. You should port match the manifold...requiring you to take the manifold off.

 

FITV and IACV do similar, but different things. FITV causes a vacuum leak when the car is turned on, but closes that leak once the car is warmed up. It can be problematic so I suggest you open it up, and turn the big screw by hand all the way in clock wise. They also sell FITV delete plates.
You will still have to use your IACV, just leave it connect on your manifold. FITV doesnt have a spot for the plug, its all manual. B series have both FITV and IACV.

B TB will be a direct bolt on to your D. There will be no problems with MAP or TPS unless the sensors themselves are malfunctioning.

Youre not going to notice any power gains unless your manifold is port matched, and even at that the gains will be small.

 

But why?

 

x2

 

can you tell me why not??... im running a stock 56mm and my edelbrock intake is 62mm.... although id love a 62mm one a type R TB is going to go for more than im willing to spend... the 60mm LS is def. in my price range.

yes i forgot to mention i have a 62mm opening for the intake manifold


thanks guys for the helpful replies

 

Ahh okay then B series TB is the way to go.


Hit up max bore if you want to get your TB bored.
