What intake mani should i run? I have a skunk2 pro series IM, a victor x IM, or theres an str on here for sale im interested in... not a daily driven car...looking to build a new, higher compression block, get a new tranny, and pro3s when i finish the next block... so this is just about the intake manifold...

victor x........

 

x2

anything larger then a 1.8 needs the larger plenum, more air and shorter runners.

 

Hands down, Skunk 2 pro series. All the recent testing has clearly shown the ITR style intake manifold to be superior on a 2L build. The Victor X just doesn't perform and shouldn't be used on anything that isn't boosted or used for drag racing exclusively. Better results will come from a ported IM and a custom intake like the Endyn IM is probably the best way to go for best overall power.

 

I wouldn't say the victor X doesn't perform. But I would say for your motor build it would be over kill. The sk2 pro will work better for you in the long run and through the powerband.

 

This is a drag only motor. So I'm not worried about streetability. Looking for a mani I can use now and in future when I finish my next block. Gonna run a sleeved and stroked block, 95x86 with 14:1 pistons... Then upgrade to pro3s... I was leaning towards junking the skunk2, cuz I feel for a drag motor, its jus too small. I'll look into the endyn. I was jus seeing what else there is for a reasonable price that will give me more power... Right now the victor x is ported for a 76mm tb. Skunk2 is prob factory, untouched (traded my buddy a diff victor x for it, he needed a bigger mani for turbo).

 

sorry for the thread jack, but will the victor x work on a D series engine?

 

In that case, go with a custom Endyn unit or the Victor X.



If you can find a Victor X that is made for a D-series engine, then I guess it will "work".

 

I pick other. Why? You have spent a bit of time and a ton of money on your set-up, why go cheap on a manifold.
I have GSR manifold that has been reworked and is able to out flow a ported Skunk2 Pro and not lose air velocity. So maybe a custom stock manifold, I went this route because I want my low and mid range power back. Not ideal for drag but and option.
Other options, the Magnus and one of BMC's.
All of the aftermarket manifolds are designed around trying to work well on a range of set-ups.
The other question you need to ask yourself is the cost of a Skunk Pro or Victor X plus porting and reworking, about $500, is nearly the same as a high dollar custom manifold.
With the Bore, Stroke, compression and Cams your running I would think something custom would yield the best results.

Don't choose an IM until you read the following:
http://www.team-integra.net/sections...?ArticleID=466

You don't choose an IM based on how much power you want to make, you choose an IM on where you want to make the power. Size is important for bigger numbers, but if you pick an IM for the wrong range, it can have a negative air flow effect in the RPM range that you are driving.
