Thumbs up

I was wondering what some of the popular swaps are into an FC. I've been in the Nissan Camp for a very long time, so all I know is SR/KAT/CA/RB. I know there are several different models of engines that were put out my mazda. I'm looking for something with turbo, and something that has the potential for 220-270 HPs. Also what are some possible JDM engine swaps? I apoligize for my ignorances ahead of time.



And how easy are the swaps, lets say going from NA to a turbo engine,is there a lot of wiring involved? can any engine form a FC or FD fit into a FC chassis?

engines from 3rd gen rx-7 (13b-rew) do NOT fit into an fc, then engine mounts are located differently



doing a n/a to turbo swap is a pain in the ***. just buy a turbo and save yourself the trouble of wasting $



btw 90% of thos "jdm low mi engines" are nothing more than rebuildable cores ONLY, so dont think your just gonna get a jdm turbo 13bt engine/tranny combo and swap it in and be ready to go without REbuilding the Engine

Ok there are many swaps that you can do. Some of the popular ones are 13B-RE cosmo, and 20B cosmo swaps. Both however are expensive, and doing those you should start with a good T2 body to save the trouble of swaping rearends. Another one is doing the 13B-REW swap, as said in previous post motor mounts don't match up. Easy fix custom motor mounts I've seen them around but don't remember at this exact moment who makes them. Oh yes custom motor mounts are required with the cosmo swaps as well.

There is also the LsX swap, the V8 swap will give you what the rotary needs torque. The down side to it is Many rotary guys will bust your *****, adds 60 lbs to the front of the car destroying the 51/49 weight split in the FC. With that your cornering will degrade a little. Well thats a few of the swaps people are doing.

I make bolt-in mounts for the REW. My mounts allow the use of stock turbos, and should clear most FD single turbo options as well. In addition, FD downpipes come very close to fitting FC exhausts.



Im having some issues with my site at the moment. The content seems to be working fine, but the on-site ordering is not. You can PM me for ordering information.



Heres some pics of the engine installed

was gonna say the same exact thing.



People are doing all types of swaps. The S2k motor has been done, anything you can think of as far as a turbo nissan motor goes. The grand nat motor has been done.





Pretty much if you have to ask how much it costs, you can't afford to do it.

The REW swap is as straight forward as any other rotary engine. You will want a standalone, especially considering the REW is speed density. What one is simply a matter of preference, and what your goals are. That isnt really a question I could answer for you. I will say this though. There is nothing unusual about the REW as far as ecu options go. Not all can control the stock twins, but a little research into what 3rd gen owners are running should answer any EMS related questions.



Everything aside from the engine mounts is typical of any rotary swap in an RX7. You have oil lines and coolant lines to worry about, what water pump you want to use, etc. There are plenty of options, but its something Id decide about at the beginning of the swap.



Almost anything I have to say about the swap can be found in my swap thread(despite me never finishing it, most of the details of the swap were worked out) I linked to in my first post. If you have any specific questions, feel free to ask.

so rebuilding a rotory engine, how is that? very hard. I'm pretty mechanically incline... so just wondering



the cleanest shell that I could find was a N/A model. So in order for me to swap it from a NA to Turbo is what? I'm still inthe dark about this, been looking at the site all-day and not really coming up with anything.



FC NA ----> FC Turbo



need:



engine, ECU, harness, tranny, rear end? (by rear end are you talking about the diff?)



FC NA-----> FD Turbo



need:



engine, ECU, harness, tranny, rear end, custom mounts?



how hard is it to put in a turbo on to a NA engine?



I don't need tons of horsepower... which would be the easiest for me to do
