13B Turbo FC S4
 

Hello everyone, Im new to Mazda Rotary engines...I already searched some of my questions, but I was not able to find any match.

I bought a JDM Mazda 13B Turbo FC S5 engine. And Im trying to clean all the parts ...teardown.

I want to know what 13B components can I eliminate....for drag race functions only. No aircon, No powersteering

Can I eliminate the air pump? from what I read ...its just for emissions, but Do i need to do anything if I remove it?

Others? Remove...then what?

How can I make it simpler?

I will also remove the whole bracket for the power steering pump and aircon compressor

But I dont want to eliminate the oil injection system

By the way, im planning to use Megasquirt engine management.

Currently, all the parts are removed....Im cleaning all the parts and I painted the side housing....the one in cast iron...as what I usually see when I search about rotary engines.

Thanks:)

The air pump, A/C compressor and P/S pump can be removed. Something to consider with removing the air pump is that the alternator/water pump belt can slip. A double alternator pulley or "yoohoo belt" (small belt stretched between the main pulley and water pump pulley) can solve this problem.

Do a search of the 2nd gen section for "emissions removal". Use advanced search to specify thread titles and target that section only.

gut the dash too when you take out heating/air conditioning

Thanks for the reply...read a lot already. Thanks :)

S5 engine?..get rid of the OMP if you can.Seeing you are going megasquirt, I would,and just premix the gas.
The S5 OMP is electrical and is prone to failure.It is an achilles heel in the engine bay.

Thanks for the replies...:)

I already have a Mazda Rx-7 FD3S....just bought it 2 months ago. And I guess my extra 13B S4 Turbo engine will be of no use as I have read here that its not worth the hassle to install the S4 FC engine as an extra engine in the future in my Rx-7 FD. Maybe Ill be using the engine in my upcoming Mazda pickup.

But the bad thing is that the 13B turbo S4 FC engine I got from a Japanese importer is with an automatic transmission and not the manual type

Anyway many Thanks:)

I want to upgrade my 13B FD engine to megasquirt MS1 V3 engine management system. Is is really tested already to use the two original CAS sensors to trigger the megasquirt? I got confused regarding the thread about the 13B FD engine in a Volks bug.

Theres no solid write up(with pics) yet of the application of megasquirt systems with 13B FD engines.

Im a little familiar with megasquirt...I am using two....one in my Mazda Z5 DOHC and a Mazda FE3 2.0 DOHC engine. But Im new to rotary engines....I want to make sure that the 2 factory CAS can be used with megasquirt before I start the project.

Many Thanks:)

there are some really good threads on here about depowering the steering rack. But I have read that some people like the steering with just removing the pump.

Thanks for the suggestions:)

S4 engine to S6 body
 

I was thinking of still using my S4 13B Turbo engine in my Mazda Rx-7 FD....

And being that the mounting points is different...

Can I simply modify the oil pan to shape like a 13B-REW oil pan and machined, drill, tap holes for the engine support of the FD on the S4 Rear Iron plate? Has anyone did this?

I will just toy with this S4 turbo engine than just it lying around in my garage.

I plan on using megasquirt for it.

The opposite has been discussed before..mounting a 13B-REW engine in an FC
