Headers, headers, HEADERS!

Couldn't you make an extension to move the throttle body out and tilted down some. I know there is someone one this forum that has a mill and could make something like that for you.........

....or just reverse the intake?? I thought I saw this done for boats and 911 conversions?

Here's an LS7 in a heavily modded Fiero that was reversed...

I'm gonna go remove my lift plate again and scope that out.........FGI
My STM's come up with the best shiznit sometimes.
Oh man....I just recognized......FRH
We need to start a 944 hybrids acronym wiki.....

I remember pics from cricketville that had a reversed intake and the air filter was in the battery tray, cant seem to find em though.

That took all of 5 minutes. The Vette intake with 5.3l throttle body comes right up to the firewall area perfectly and the rear area (now located in the front engine bay) CLEARS the hood line. However, If you wanted to do this, you would have to remove/modify the fan blower and cut a hole there for the air filter set-up. I think MatthewB did this with his Ford Overhead cam engine. I don't care about AC, but I want heat in the winter.
There would be another PLUS to reversing the intake....The stock 944 Throttle cable would hook right up to the throttle body.... Hmmmm

While we are on the subject, I do recall the 944 fan blowers being high$$$. Has anyone ever put in an aftermarket blower? If this can be done relatively simple/inexpensive, I may just do this reverse intake setup....POPP
and FRH...has a nice ring to it.

Man, there seems to be no limit here...RH sure screwed the pooch. "The 5.3L truck engine intake will not clear the 944 hood"...Where have I heard something like that before? Dey don't know us bewwy well, do dey?

So, headers = done?

The misinformation/propaganda RH puts out misleads you to wanting to put in the LS1 with their kit. The truck intake is 3" higher than the Vette intake and is a Torque producer. the Vette intake goes right on the 4.8l 5.3l and 6.0 iron blocks and fits nicely under the hood with at least 3/4" X-member drop and while maintaining 3/8 to 1/2" oil pan to xmember clearance. As far as Oil pan for the LS/LM7 engines, this $225 Moroso 20140 is the schiznit with 1.5" sump to x-member clearance. When JJ figures the Driver's side header, the sh*t will hit the fan over at Gestapovile......chirp chirp Byatches

"I think I am the first to put in the 5.3l Truck motor. The Vette intake is Swcheet. Can the Throttle body be trimmed on the forward top of it for a little more hood clearance? Thought somebody on Gestapoville mentioned that...."

Nope - I'm doing the 5.3l HO (all alloy block) swap

I'm using an LS2 intake with a big 90mm TPIS throttle body. Never thought of reversing it, though, and I've already cut out a big hole in my hood. I do like the look of a hood bulge:

I had to cut a slit out of the hood to fit the throttle body, pics are over at cricketville (ill have to dig through an move everything over one day) It takes 2 mins and a dremel, not difficult to do.
The hood buldge looks fricken sweet tho

#7 primary is done. Just working out the bends on #5, and will be grinding the protrusion on the block to make'em fit.

Do you think the tubes can be cut off right at the flange, then the flange set up on a mill to clean the flange?
If so, I can do this part of the Modification quickly and with precision.
Woo-hoo.....exited, but patient.....

I would think so, though the only thing I might be worried about is that cutting them on the outside of the flange removes a bit of straight section before each primary does a bend. That initial straight section may help scavenge the CC and aid flow. Also, the best way to weld the primaries is on the inside of the port rather than the outside, so you couldn't use the port itself as a straight section. I'm no guru so maybe it's not enough to make a difference - just thinking.

does it look like there will be enough room in there to wrap the exhaust? I have all the stuff and would hate to see it go to waste

I'm still running into some interference in #1, #7 and the top steering knuckle. The primaries are very close together - I was even thinking I might need to warp them a bit (squish them) to make them fit.

I have the 1" drop spacers so this is probably why I had good clearance when I checked them out at first. I wonder if the manual rack sits lower than this power rack? If it does then the full 1" xmember drop is not needed.....

FINALLY!!!

Sorry it took so long to get to this point. It was the #1 primary that was giving me all the problems, but I've got it licked:

This design meets all of my requirements:

- fits (duh)
- you don't have to remove the steering shaft
- you can access the plugs
- it uses as much of the original header as possible (in fact, all of the original parts are used)
- and it takes into consideration different vertical block locations, i.e. works just as well with a dropped crossmember than without.
- clears the brake MC
- there's even space for your header wrap, Tet!

I'll get it tacked in the next couple of days, then take all the dimensions and angles and post them to the board.

holy carp!
Im excited.

FNA....This deserves a PORH moment of silence......
chirp...

chirp...

ohh I see, that initial kink avoids the steering knucle.

...and leaves a little more room for the #7 primary (had your wrap in mind). Otherwise, those two would be mashed together tight. Welding them would have been a real PITA.

Johnny J, can you post a pic of the driver side installed, showing clearance @ the MC area?

Gang, as a lurker I must say, VERY impressive! That is what this place IS all about! (not much good for my 928 though). Keep up the progress!!! Well done!

Don't worry...the 928 BH adapter is coming. Maybe more. Care to help?

Yes, and don't forget the motor mounts! I'm beginning to wonder if these 2312 headers can go into the 928........
Bring the nails, I've got the hammer......the coffin is ready for the RH crew.....
PORH.....
