How much of a difference would this IM make on and stock ls/vtec turbo.?
And How much Psi will i have to push to get 300 HP

 

skunk 2 intake mani made a huge difference on my 95 b18c1 n/a setup...don't know about turbo setup yet...I will be findingout soon...

 

From what I understand you will pick up a few extra horse but the money could be better spent elsewhere. If you already have all the basics done then go for it! I would make sure you have important things first like bigger injectors, bigger fuel pump, and a 3" exhaust.

 

yes i have all of those things

 

What VTEC head are you running?

 

I'm also curious about power gains from the Skunk 2 Manifold. I'm running a GSR head on an LS block. The block is bored .25mm over and fitted with SRP 9:1 Pistons and Eagle rods. I'm running the DRAG III turbo kit and Greddy Power Extreme 2 exhaust @ 14.5psi.

 

Your motor sounds a lot like Lane's, his if you don't know is a stock sleeved B18C running JE 9.5:1 81.25mm slugs, Eagle rods, Portflow head, Hondata, and a T3/T04E... We actually originally had a SK2 IN manifold on it when the motor first was build almost 3 years ago... Since then it's been changed over to the Victor X and retuned many times... It did make more power with the JG/Edelbrock IN manifold and he only runs it on 12lbs... I'm sure a lot of it was fine tuning but we went from ~350whp to 375 at the same boost level... In his 2600lbs. full interior EJ6 he still runs consistent 11.50's which isn't anything special but pretty good considering the motor and the fact that he only runs 92... Just another manifold to consider, it's actually is the most popular on our (and customers) built FI motors...

Forgot to mention, since we don't deal with too many stock GSR turbo motors (still running the dual runner IN manifold) I can't tell you how much of a gain you're really going to get... I know one thing tho and that is I really dislike the P72 IN manifold...

 

i definantly noticed a difference when i put one on my b18c1,,, definantly worth it IMO.

 

I think its worth it on the LS motor if you have all your other bases covered. ie, good turbo, 3" dp/exhaust, hondata.... Basically it spreads your poweband and gives you more usuable torque. You will loose a little low end and a little peak torque but you gain some hp and it spreads your torque higher in the rpm range. Its 300$ and simple enough to install. Definitly worth it if you don't wanna go to a vtec head.

 

I've been pondering picking up one of these. I've been debating between the Skunk and JG manifold. On the other hand, from reading previous post about the JG manifold, it would only be worth it if you're pushing "enough" of boost. I don't know if my 14.5 psi would be considered enough boost for the JG.
