looking to put a 3rd gen intake on my FC when i install my FMIC
do i need just the upper or both upper and lower?
thanks
i did a search with poor results.

 

just the upper....there is a writeup somewhere around here...search in the 2nd gen archives...

 

thanks

 

you need an adapter to use the fd UIM to bolt to the fc LIM, and i believe youcan only use the s5 LIM...

 

In case you were wondering, the FD LIM doesn't fit because the ports are in a different place. You CAN use the S4, if I'm not mistaken, but for some reason it's harder to port match (Don't quote me on this, could be completely off). Most people port match S5 manis, but other make (fairly expensive) adapters to make it a bolt-on issue.

 

I can have the adaptors made. japan2la has a cnc machine with my adaptor.
Thanks Robert

 

how much?

 

About $250 shipped. Feeds is $285 plus shipping from japan.
Thanks Robert

 

Let us know how many you sell at that price.

 

Well I have sold about 10 so far.
Thanks Robert

 

Is it really worth the money? how much do you get out of the intake?

 

I guess if you are shelling out that much cash for a chunk of alumium 2x10x1" thick with 4 holes in it and a couple of longer studs ,you better hope it's a lot.

 

Wow, that's alot of $$$.

 

Of course no one has asked this question...what exactly will you get out of putting on an FD intake? HP gain?

 

look 3 posts up

 

its not worth it man. if youi looks at teh primasry they are actually smaller thatn the s4 and s5. And if you are pushing air through them to the LIM s5 or s4 which at bigger you lose Velocity. Over allits not worth it

 

There is a couple of people on the forum did a dino run before and after. I'll do a search and get back to you all. We only made these adaptors because of what people were looking for. There was a increase but can't remember.
Thanks Robert

an FD upper and TB is just 2 of many mods

 

Curious...what lower gasket (block to lower manifold) do people use when using an S5 LIM to an S4 block? The 2 gaskets are not the same.
