What intake manifold is bolted to my Weber 48 IDA?
I picked up a 12A pulled from an SCCA '79 FB last week. It came with an MSD Blaster ignition setup, full road-race style exhaust (not RB, but not sure what), a wide-band setup, and a Weber 48 IDA setup. Also came with the stock intake manifold w/Nikki carb. Oh, and a rebuilt Miata 5-speed tranny. :)
I pulled the Weber off to have a look at the intake ports to see if the engine was ported or not. I figured it was probably at least street ported since it came with the Weber 48 IDA and the wideband, but I couldn't really tell by feeling around in the intake ports. But I digress. I examined the Weber and intake assembly and don't recognize the intake. It seems like a custom job. Here are a few pics: http://img21.imageshack.us/img21/7720/weberim4.jpg http://img842.imageshack.us/img842/143/webim3.jpg http://img33.imageshack.us/img33/438/weberim2.jpg http://img21.imageshack.us/img21/5033/weberim1.jpg There are no markings on it that I can see. The ports appear to have been polished at a minimum...perhaps even opened up. As you can see, there are lots of welds around the base of the runners. Has anyone seen this before? fm |

Moved ;)

i have no idea what it started as, but i would agree that it definitely looks altered.
|
Could be a DCOE manifold that was altered for use w/ an IDA. Thats my guess
|
that was my first thought, too, but then i saw what appears to be some kind of funky alteration at the primary ports (first photo).
|
could also be an old manifold for a "short" port engine as well, which had to be ported out beyond the original casting and in turn fill welded to fit the later tall port center iron
|
makes total sense. i think you nailed it.
|
lol, you would be amazed at what some people do to make things work on a budget ;)
(Ive "modded" things worth much more than their respective appropriate replacement part, just simply because I could make it work with a little fabrication and minimal funds) |
