Fs-fe!!??

Umm.. thats the engine thats in my girlfriends 626.. EXACT engine...
 
Well, there is something different about it since it's making more power than the 626 engine; The 626 featured the FS-DE 2.0L, but that's what it looked like back when it had no VICS/VTCS (I beleive), the old head casting, and the distributor ignition with plug wires. =) Just an old school FS-DE. The differences are most likely internal, and, if that one page is right, it's supercharged, perhaps? Unless 'blown' is slang for something else in this case. =)
 
yeah you are right it is 145...guess i overlooked that. Still a very interesting engine. Probably obd1 though and there would be ecu issues too.
 
bah, I wouldnt bother about that engine. More interesting than that is the FE3N which is a 2.0L and its the best 4-cyl motor ever built by mazda.


SPECS:

HP: 170hp@6000 rpm (9.5:1 compression)
Torque: 160ft/lbs @4500rpm

Turbo @ 13.5psi HP: 260hp (8.8:1 compression)
Turbo TQ @ 13.5psi: 283lb/ft

BORE: 86mm
Stroke: 86mm
Forged full floating pistons/rods and crank.
Double valve springs
aggressive cam timming and lift.

You might as well just get the FS-ZE. I'm surprised none of you have gone that route yet. Kyle, you could have done the swap for the cost of your rebuild....

Not to mention a better rod ratio than both the FS and BP. But it's a completely different engine than either, and would take a bunch of custom work. One just may be my next project though......

FS-ZE doesn't work on US spec ECU and the J-spec ECU doesn't really help either. The FS-ZE is a waste for any type of swap into the A-spec cars. UPSMan had a full J-spec conversion including body, lexan windshield, and motor...but it never ran right and was never faster than the better built N/A FS-DE's here on the boards.

Would the fs-de ecu work with the fs-ze motor or would you have to buy another ecu from japan also?
Sort of...it would make about 4 more hp than the DE...simply because the stock engine controller would barely notice any differences...could be a little more than that but its doubtfull...

Now with proper tuning it is safe to say that you could make upwards of 130whp with just the ZE and standalone...possibly about 140whp...and over 150whp after normal bolt-ons...I have yet to see a properly tuned FS-ZE though, with a "real" standalone...some guys have used various piggybacks...and gained like 10whp over the stock DE...and one guy used a Unichip thing, and was not getting very good results either...But its rated at 170 PS, so about 163BHP...and the DE's 130bhp claim is pretty accurate for the most part...So its my bet that the OBD-I cars in Japan with the ZE are dyno'ing at 130whp or so bone stock...pertaining to FWD, not AWD cars...and obviously with a manual gearbox...

its completely different with the OBD-I cars too...some Probe guys did it, and were making nearly 140whp with just the OBD-I j-spec ecu from corksport and little things like UDP's and cat-backs (it was an easy swap for an OBD-I car...not the case for us)...so yeah the engine has some potential...but as soon as everything hit OBD-II in 96, this swap became a lot less popular...
