Any interest on an ITB group buy?

I've seen some videos on youtube where they've got their engine's running without a plenum or anything, just the itb's straight up?
what kind of problems can that cause, because it sounds freakin' awesome!

So what's a "vacuum log" that z31maniac was talking about?

Anyone interested in taking over the "point of contact" person for this?

I've decided to go 24v, so not to be a dick, I'm not going to keep messing with this.

If you are interested let me know, I'll let Kevin know, and give you all the info he has given me.

I'm really considering doing this along with a 3.0L job on my m20, rather than a S52 swap.

Its only the ecu side of the deal that I'm confused on, do I have to come up with it all on my own? is there at least a base tune to run off?

Can I just run venturi's and those small foam filters rather than making a plenum? I do have a S54 manifold sitting around


Just listen to this setup(not the one being talked about,just found it on youtube)

You could run just the filters, balanced airflow would be better than unbalanced cooler airflow, but running just the filters will bias the power curve even more so to the top end.

Homemade plenums aren't necessarily super = on airflow distribution, but there is alot of info out there to get them pretty good.

You'd need to use an EMS that can do a AlphaN/MAP hybrid, their ECU will, but I don't know when it will go into production. I don't know if MegaSquirt will support a hybrid map like that, but it shouldn't be hard to find out with a little searching.

Run AlphaN down low, like 1500RPM and lower, and then the vacuum log should provide a good MAP sensor reading above that due to the airflow.

bring this back from the dead. IM in for a group buy!!!

I'd definitely be more interested in this if their was a more solid solution for that ECU, I just don't know if I want to start down that road. I feel like it has a good possibility of becoming a money pit.

maybe some ecu guru's can through out some possibilities?

Does anyone know if megasquit is a possibility for this?

Yes. Ask rs4pr03 about his setup. I'm sure he'd be glad to build you a custom prewired set-up as well. Or you could just buy his car.
