RB25DET Intake manifold??

[IslandBoy]

If i am changing the manifold to the Greddy type, do i have to get a new gasket to bolt on to the engine head?? If there is a gasket, does anyone know the Part No. ??I need to know if the Greddy type plenum also adapts with the step up idle solenoid?

i thought the mani came with a gasket...mine did...anyways.. it depends on waht kind of condition the gasket is in..some people end up re-using there old one..some dont.

you have to get an adaptor plate for the stock Rb25 TB ro fit..other wise i think it made to fit the q45 TB..

THANKS...BUT I AM CURIOUS ABOUT THE STEP UP SOLENOID FOR THE COLD START / AIR CONDITION. DOES IT FIT ON THE AFTERMARKET MANIFOLD?

the Greddy and ISIS intake manifolds have provision for the IACV/AAC/FIC sensors (although the only sensor that actually bolts onto the manifold is the IACV) but by swapping over the manifold it'll allow you to retain all factory sensors and solenoids.

From both manufacturers they do not come with new gaskets... perhaps some may have been an expecption prior.
