Yeah that's exactly what I was thinking, that intake would be totally badass man.

There's a few pictures in my thread on pelican here I haven't updated it in a bit because it just kept being little things that didn't photo well. It's currently ready to start if we could just figure out the damn no spark. http://forums.pelicanparts.com/off-t...bout-imsb.html

thread was dead for a while but you boosted the octane on it here as of late. Keep plugging away and showing us pics. Looks very exciting.

I just tried a test fit with the intake manifold tuned 180 and there's not enough room for the throttle body because of the tunnel and I cannot cut out any more metal then I've already cut for the access panel. Stupid me DID NOT take any pictures of the clearance issues. So all the work on the rear window intake scoops was for NOT. Luckily I only took the passenger window out so I just have that one to put back.

Damn it!
What about a 4 BBL EFI intake with a 4BBL throttle body and a carb hat pointed toward that scoop in the driver's side window corner?

Nope nothing will fit that is any taller then the stock LS3 intake.

I know in one of the hundreds of threads I have read, someone took a 4bbl intake, put an elbow on it and attached the TB to it. The elbow could give you the flexibility you need to make it work. If I come across it, I will send you the link.

I think it'll fit on the old air cooled 911's. Most of the new LS four barrel manifolds I've seen are just as tall as the LS3 manifold without the carb installed. My thoughts now are to try and run the ducting from the rear side window thru the 3" wiring hole as show in picture along side the motor to the airbox on the back.

Started cleaning up the unused Porsche wiring. Deleted all the motor vitals and separated the gauge wiring, AC, Alternator and starter

Using both the Porsche and the GM oil pressure senders. Porsche will work the cars gage and GM will info the GM stand alone computer.

Wiring is getting better, notice the fuel inj, O2 sensor wires and such cut and bundled on the Porsche computer. Waiting on some more info on whether or not to connect some of these wires together or maybe ground some to make the Porsche computer think a motor is hooked up or maybe just pull fuses/relays.

<--from Ebay. Hey, much cooler than a fiero. I'll def be keeping an eye on this one. I just started my terminal leave--USAF. I didn't know about the oil pressure relief valve issue until I asked a GM tech at a car show, then searched on this board. I'm sure there's a TSB or recall. First I thought the sender getting too hot, then the oil not draining from head, then I put in a trap door pan from V8roadsters etc.. The fix, new oil pump.
