Affordable ITB's
I'm not sure if this has been posted before, but I was browsing the net and I found this site that among many other products, has Weber IDA-style individual throttle bodies. Everything but drilled injector bosses and fuel lines are included, and they are actually just a few dollars more than an a Weber 48 and considerably cheaper than the 51.

I was planning on doing a ida intake and carb on my car, but this seems like it wouldn't be too much more expensive (going the megasquirt route anyways) and probably produce more power and better drivability than a carb could.
So figure $545 for the throttle body, $400 or thereabouts for megasquirt, another few $$$ for some good injectors and $250 (or less if used) for an ida intake. Not a bad deal, IMO. Grassroots motorsports got 25 more RWHP just dyno-tuning the factory intake assembly with megasquirt, I can see this picking up 10-20 more over that.
Just for reference, the Fuji racing kit is $1500 with no engine management. So basically twice the price although it is much more complete.

For your info, the fuji racing that you say cost 1500$ that includes an intake manifold in there also for that price if you haven't noticed, the actual kit is only 785$ for a 47mm and 950$ for a 50mm. Link is here:

I found a post somewhere that said that Tweakit.net shut down this year...so much for a site that I used to drool over Anyway the ITB's that were sold through tweakit are made through www.efihardware.com they don't seem to have the manifold you would need nor do they have the nice airbox that Tweakit used to sell. Kinda glad I picked all that stuff up before tweakit went under, however at least the throttle body manufacturer is still around....

Still seems expensive although it is pretty. The Fuji one was just perfect.
I remember someone saying there was a guy in the states that sells microtechs and ITB's for affordable price but I never paid attention since I didn't need it but now I'm looking for it LOL.

My plan is more simple:
RB Holley manifold
Old 750cfm Holley (3310 code, AKA "the genericest 4160") which is 42mm * 4, modified with a dab of weld to be mechanical/1:1 operation
Standoff injectors mounted in the carb hat, maybe. Still thinking about it. I'd LIKE to route the injectors through the boosters, but that seems like a lot of work for unknown gain.
I paid something like $120 for the manifold, and had the carb as a leftover from my big-block Ford days. The carb was the best running Holley that I'd ever experienced, so i feel bad turning it into a throttle body, but, well, I'm probably never going back to carburetion ever, so it's do this or nothing. If i ever do go back to BBFs, I'll be using injection on that too...
Innovate sells a TPS kit for $69, I think I can do it cheaper.
