Hi, i have a an FB with a 4port 13B fitted, its running a 12A nikki carb and intake manifold with an adaptor plate (I bought the car this way)

I want an opinion on an idea, would I be able to fit the supercharger from the toyota 4agze engine, i can get them really cheap, and what would this entail.

I know ill need a new intake mani made up etc. but what problems am i going to have with belts etc.

Will i be able to run the stock carb (with bigger jets) for a while until i can afford a better one?

On the 4agze the supercharger is able to make a bit over 200hp with the higher speed pulley set, so this sort of power should be possible on the 13B too in theory right.

Thanks

 

Anything is possible. If you can find them for cheap and have the skills and resources for the fabrication, then go for it. A project like this can go many ways. It can be easier then expected, or you can run into major design problems that make the project hell.

I would recommend a much bigger carb. The factory Nikki flows 390 cfm. A SC 13b is going to need some more juice. Boost changes everything. Not having the proper supply of fuel and AFR's under boost will kill your engine. I wouldn't recommend trying to "get by" with any parts during this project. Tuning with a wideband would be a good idea. If you are going non-intercooled like the Camden unit, then you should beef up both your oil and coolant cooling systems.

As far as the belts go, it depends. If you can line up the pulleys, get the right belt configuration, and balanced then it should work. I would guess the less accesories the easier it would be.

I have seen a few threads in the past years of members using a variety of SC's on rotaries. Search around and gather some info.

Good luck

 

I have heard someone on the forum say that many factory superchargers won't flow enough for a rotary. Something to do with the fact that rotaries use all their displacement every revolution compared to a piston 4-stroke which uses only half its displacement every revolution. Therefore, the 13B has an airflow requirement more like a 2.6L piston engine. The 1.6L 4AGZE probably most likely requires less airflow than the 1.3L 13B. Just something to think about before investing alot in fabrication for a supercharger that might not flow enough on top end.

 

This question comes up from time to time. The 4AGZE supercharger will not flow nearly enough for a rotary.

 

Will not flow enough and it is designed for EFI. It could fab up nicely on a stock GSL SE and provide some low end torque. Most hp I would expect is maybe 10hp.

 

Yeah I agree that you don't wanna use a 4AGZE S/C. Cool thing about them thou, is that there's a switch in the cabin, and you can turn it off/on when ever you want. The pulley has a clutch.

what about an Eaton charger off the old T-bird Supercoupes / Cougar XR7? 3.8L V6, should put out enough juice. But those were also EFI.

Of course this would be a huge task, youd have to build the engine to handle boost, and make a custom intake manifold yada yada yada

 

You can use an Eaton supercharger, but you won't get a whole lot of power out of it, and you have to use either fuel-injection or blow-through.

You don't have to do anything special to the engine to make it "handle" boost, just drill and tap a hole in the front cover for an oil return line for the blower. You could use a modified 12AT/13BT manifold if you want to use fuel-injection, or just a stock style one for blow-through. You'll have to boost-prep your carb if you go that route, too.

In my opinion it's better to just save up and get one of Atkins' Camden Supercharger kits. It's a bolt-on affair and they make good power.

 

camden id the way to go. like there is a 7inch kit for 3000 grand if you have that kind of money

 

Has anyone ever tried using the Lysholm compressor off a Millenia S? I don't recall all the specs but the engine was set up as a Miller cycle so it was not your ordinary 4 stroke boinger.

 

has anyone (non rx-7 guru) actually installed the Camden Super Charger?

Their website makes it sound so easy. Too easy

For $1300 (5 inch blower) , what will be the increase? Any carburator issues

 

not a lot but it has some tourque i knew i guy that intalled one and he said it was rather easy from what i unders stand doesn't basicly eleminate the intake mani and air pump for the super charger and then the carb bolts on top. basiclly? or is that off cause i have not seen one in forever just the pics on the website

 

this set up is super easy to install . even if you are not a rx guru. but to make the power desire you have to go with a different carb like a holley or a webber oer. the water pump and housing needs to be replace with an s4/s5 water pump so you can install the tentioner for the pulley other than that no ther mods . if you want good tuneable carb go with oer and they handle the boost better. if you are going to invest in the camden i would also look in getting the 7" oppose to 5 and look into water methanol injection for cooling purposes. cheers.

 

ya, just like I thought, the web site was "too quick + easy"
