Default turbo manifolds.

ok guys I finaly got my LQ9 built and dropped into my 240sx. Now I am going turbo, but the truck mani's dont clear the frame and body work, are there a slimmer type of gm manifold I can use? Open to suggestions.

the c5, c6, z06 manifolds to the corvette hug the block better and might work.

Another idea might be 98 or 99 camaro manifolds. They are made of steel, and can be cut and welded easily.

The vette ones can't be used unless you use either motor plates or the vette style mounts. Fbody mounting location will not work.

I used a 02 Fbody manifold on the drivers side same as stock on that car. They hug closer to the motor alot better then a truck manifold, basicly dont kick out like the truck ones.

How far off are they? Can you cut of the flanges and weld on v-bands?

waiting for the c6 manis to come in, I will find out if they will fit. I have an s13 240sx im going to have to see if I can stick the turbo there too. I was going to put it on the pass side near the battery and just move the battery to the trunk. I dont have enough room to run a 4 inch downpipe on the drivers side. what size dp does that s14 have?

I'm going to be using C6 manifold flipped backwards on my GTO. There is a build thread on LS2gto.com of a guy doing that on the east coast.

if the flange is interfering with the frame cut them off and tig weld 2.5 stainless v band clamps on. Make sure you preheat it to 250 to 300 deg. the use silicone bronze rod or 308 rod. After you are finished wrap the welded area with a fiberglass wrap and let it slow cool for about 2 hours. Hope this helps. Mike Salkowski
