I have a 98 GS-R, built bottom end (but stock cams), and turboed at 10 psi.
How can a JG or Skunk 2 intake manifold help me? I know that the ports are bigger, so there is better air flow, but how exactly will this help in my application? What kind of whp gains could I expect, roughly?
Also, what kind of gains could I get from Cam Gears? Could they give me a good 15 whp after tuning?
Thanks for the help...
P.S. Also, what brands are recommended. Remember, these boltons will be bought for turbo application, not n/a.

 

I have the edelbrock intake manifold. I did a search and found that people recomend them for FI. I am still in the process of getting a turbo but i could feel a difference in the edelbrock manifold on my NA setup. The best thing i think is that the butterfly vlave is gone, weighs less and flows better. I would recomend it; but as actual numbers i have no idea, you can also get a larger TB so it does allow for further upgrades. Also it has bosses that can be easily machined for nitrous or whatever

 

you can open up the stock im and remove the butterfly yourself. and get a ford trottle body you will get much more power for about 50 dollars. if the tb is used.

 

The edlebrock intake manfiold is supposed to be one of the best out there aside from the AIR manifold. Mine will be up and running with one soon.
In a turbo app. i cant see how changing out the throttle body will help at all. I mean your probably running a max of 2.5" IC piping which shouldnt be too far off from your stock TB. When it is all pressurized, what difference would going to a 3" TB make? It will just get to 3 inches 3 inches sooner. Sorry if this only half way makes sense, been a rough day

 

There is a lot to be learned by running a larger TB. Turbo AR housing sizes can be adjusted much better when you use a larger TB and you can use a substantially larger AR when you do increase the TB size without sacrificing any TQ or bottom end power. This allows for a much broader tuning area for the bulk of your power. Remember, a small TB is like a straw in between 3" pipes. Any given amount of air let out the motor to spool a turbo can is directly determined by the amount of air let into the motor. Therefore, if you are strictly thinking about PSI and not CFM of your turbo system, then you might be missing out on a boat load of power that is just wasting away.

By the way, our manifold has all these items taken into consideration. We designed our manifold strictly for turbo use, any amount of pressure, from 6 psi all the way to 60! All manifold dimensions have been precisely determined to be as efficient in air delivery as possible. Our manifold is used on some of the fastest cars in the world, from Lisa kubo to Ed Bergenholtz, our manifolds always perform the best for the buck ( period ) If you have any info, please let me know. Don't be fooled by the hype and glitz of some other manifolds, our manifold gets the job done better!

What company is this? I am leaning more towards the JG Edelbrock manifold because several other Skunk 2 parts have a bad reputation and I've never heard anything bad about JG Edelbrock.

 

skunk is great for all motor but the short runners of the JG are ideal for a FI setup. i'd use one a B if i ever get the $ to build a B that is btw the AIR manifold will run you $1300 is think, all carbon fiber with a CNC aluminum flange

That's assuming you're running 3" charge piping. Most people on here aren't and don't need to for there application.

 

i run JG on my setup... im right at 290 whp on a mustang with it on 9 psi... it improved my top end greatly over the skunk.. JG =

 

Look into the venom manifold. Not the new circular style but the old square. You cant just drop it on and start up because its basically a drag manifold and youll have to mount your IACV, but its definetely the best bang for the buck manifold

I gained 18whp on a 16psi A6 @ 5100+ and 14-15tq @ 3350+

THe plenum is huge as hell, runners are thick and short, got mine for $200 for the polished version

BTW- The gained HP was over the y8 manifold, which is already known to be the best sohc manifold. On a B series Im sure even more power could be made

That was an examle. A 68 mm TB is about 2.67" in dia. Always try to keep the charge pipe no smaller than your TB, and vice versa. Having a 68 mm TB will do nothing if your charge pipe in only 2.5" Think of your air iunduction system like a chain. It is only as strong as it's weakest link.

Seriously? . . . . look at his screen name . . .

 

isnt it better to keep your chrage piping smaller than your thorottle body? It would suck to have 3" chrage piping entering a 2.67" TB. There would be no difference having 2.5" charge piping entering a 2.67" TB then a big intake manifold.
If your running 2.5" piping, there is no need to have a throttle body any bigger than 2.5". You can but its not needed.
