Wow, gota say I'm intrigued. I would be interested in the info of the shop that made the manifold. Have you had it on the street yet? How does it perform? Will the stock fuel pump feed it?

Hey, that's what my car had on it when I got it. Well, kind of. It was kind of a back-woods mechanic that did this to the original engine, and it wasn't the same carbs, but it's pretty much the same concept. I think it was these carbs. that they used, just older ones: http://www.fastbygast.com/Catagories/Pr ... ncarbs.asp I should have kept them and tried to sell them.

he motorcycle carb install has been done to 510's quite a few times. The couple set ups that I've seen in person were pretty rough. I remember a local car that had 4 Mikuni bike carbs on back in the early 90's. At that time I didn't see the point as Webber, DelOrtto’s and Mikuni PHH cars were some plentiful. However, now that the twin choke side draft market is getting a little niche, I can see why you'd do this. I makes more sense these days.

Nice work, good to see you posting here. I like the use of recycled Datsun bits like the intake manifold flange and the braided rad hose rubber! :D the motorcycle throttle cable splitter is a great idea – might have to keep that one on the books as well.
Keep us up to date on how it works out.

Did you re-jet the carbs?

I sure cared about how much power my KA was making when I tried ITBs. When I confirmed I was making less power, off they came to sell them on eBay to someone who didn't care how much power they were making.

The part of the article that talks about the R1’s 35-degree angle and some thing about a Rover is cut off. Do they or don’t they work well at less of an angle? I could see having hood clearance issues with my L20B and that setup.

Suzuki Hayabusa and GSX-R 1000s. I tried both.

DQ Volume 6 Issue 3 - Individual Throttle Body Conversion: A Dimer's world is not the path of "factory stock." There's always something better out there and good enough usually isn't. Even modern engine swaps are not immune to our need to improve beyond stock. We’ll show you how to keep your EFI yet reduce weight, improve access, and more importantly, increase airflow by bolting on individual throttle bodies.

and

DQ Volume 6 Issue 4 - ITB Conversion: Part Two: The end of Part I brought about questions concerning the electronic side of things, specifically, what would happen to the air/fuel mixture because of the ITBs and would the stock ECU be able to handle the additional air flow. I'm sure you're also wondering about power gains. I know I was!

It's likely due to the floats. The carbs are designed to fit at that angle on the bike, so the angle needs to be maintained on whatever application you use them on. Just as the angle needs to be maintained on a set of SUs.

Floats don't work very well when they hang up against an angled float bowl.

If I ever put MC carbs on my car, they're going to have to be keihin FCRs. Almost put a set on my honda back in the day. They only work good at high RPM...hence being for motorcycles.

Flatslide baby!
