k...so I need to know if there is anyone that makes a conversion kit for the motor mounts from a 3rdgen to 2ndgen, because I had the assumption that they were the same....but I've been told different....


lemme know guys

thanks!

 

In the FAQs right ABOVE this is written:

Will a 3rd Gen RX-7 (FD) motor (13B-REW) fit in my 2nd gen RX-7?
The simple answer is No! The motor mounts are in different locations as well as other issues; however if you have enough time and money it can be done. It is generally cheaper and easier however to put in a 20B (typically around $10,000 installed) than it is an 13B-REW from a FD. Here is a basic write up: http://fc3spro.com/TECH/SWAP/FD3S/rew.html

 

ummm Stillway here in Japan makes a bolt in cradle to put a FD engine into a FC. its around $480. Lots of guys here do that and use a FD engine and harness and Power FC. Power FC for FD is alot cheaper and easyer to get than one for a FC.

Its not that hard to do if you really have your mind set on it.

 

it's also kinda dumb to do when a RE engine bolts right in and has similar ports and output to a REW.

 

I've seen two people on this forum make their own cradles to mount FD motors into FCs

It's nowhere as simple as a cosmo motor, but it can be done. One guy even placed it lower and about two inchs further back because of how much shorter the FD tranny is.

 

k....thnx 87gtr....

 

I'd love to do it strictly for the sequentials and power fc like 87GTR said.
Awesome motor regardless. Also it has a slightly diff powerband as its for topend and cosmo is for torque, but its still a rotary so its all about topend

 

Haltech E8 will smoke a Power FC, unless you're stuck on the sequential twins and the OMP.

yeah I guess thats why the Haltech is so popular in Japan then...


when you can pick a power fc and commander for $500 - $600 the E8 cant even compair but lets not turn this into one more of these my ecu is better than your ecu when then question is about fitting a FD motor in a FC.

 

 

damn thats alot of vaccume lines

 

eh, when i took my FC apart it loooked like a lot and i though i'd never get this thing running again but i did..... so you'll get used to it

 

Oh, now you're going to argue location?
Since the majority of the folks reading this are in the U.S., you prices don't really apply.
A Power FC in the U.S. is easily over US$1,000 from an authorized U.S. A'PEXi dealer.
Add all the extra stuff like the Commander and the Datalogit, and we're talking comparable MSRP's - the Haltech E8 is priced easily under US$2,000.

Due to economics in Japan, importing the Haltech gets majorly expensive...as is ANYTHING not made in Japan.

The only thing the Power FC has going for it is the plug-n-play feature.
If you wanna go messing with a stock FD engine harness, be my guest.
I'd rather have a brand new wiring harness that I installed myself for peace of mind.
The Haltech E8 has more outputs and more flexible in controlling those outputs.
The resolution of the Haltech E8 will straight-up bitch-slap the Power FC.
The Power FC, after all, is just a glorified S-AFC...which I can't understand why so many hold it in such high regard.

Hey, you're the one that started this fight...and now you're whining about not starting one?

Bottom line, the 13BT will just about put out as much power as a 13B-REW.
If you're going to be sinking that much money into the engine, the difference are negligable, since with money you can change out almost all the parts anyways.
The stock 13B-REW engine mounts make it a royal pain in the *** to mount in an FC3S chassis, and even the Cosmo 13B-RE will bolt in easier.

When it's all said and done, the 13B-REW swap into an FC ends up being more a bragging rights thing than a purely performance or economical choice.
Sure, you can brang about your sequential twins, but there's a reason so many FD owners chuck those things in the first place...

It's your car...

how about we just port a 13bt and put a haltech e8 in it?

screw all that FD engine in the FC stuff... waste of time.
