why .... seriously.. i can see the v8 for the power but a v6

rotor vs. piston

I already have a V8 FB, this is going to be a commuter. Gas milage of a honda (accord but ya) and the fun to drive factor of the SA. I love 1st gens but not the engines so much.

wow.. you really should be shot.. so what your saying is you fucked up one perfectly good rx-7 and now you are ******* up another one. nothing is more fun than a properly tuned 12a or 13b in a SA.. besides the engine weight difference its also moving the center of gravity forward.. so it definately wouldnt be as fun to drive as a SA.

Did that car catch on fire 20 years ago, and then was left out in a humid climate?

rotor vs. piston

Ahhh, my favorite unresearched argument. The engine is actually about the same length as a 12a, maybe a little shorter, therefore it still sits BEHIND the front axle giving hand to yet still close to 50/50.

The difference here children is the center of gravity will be higher, slightly. But this is about the same as adding a turbo and it's hardware.

The car was "rust proofed" by Zimbol? Ya, 27 years later it looks like ***. When I get everything snug I'm sand blasting the bitch. I want to keep both of these 7's as long as I can.

BTW, I used to own an '84 GSL-SE and yes I know how fun the rotary is. I also know what a pain in the *** it is.

Also keep in mind I'm not some punk kid. So even though my ideas are hair brained, they're well executed.

My v8/FB is NE section approved LOL.

I'll stamp it with my seal of approval.

Keep it up,good work.
Being all the same is boring.The more wackyness the better!

Did you get that engine out of a f-body? I would imagine that it will be fuel injected, I would also have to think that it would be a pain to get all of the electronics working. If my rebuilt 13b ever dies I would seriously consider going to some type of GM V-8 Crate motor. I would probably run a carb to simplify things tho.

I won't get in the rotor vs piston debate, but I do like the 3800 engine. I had them in my Riviera and Trofeo. I had a coolant leak in the Riv, coming back from Denver one day. There aren't many engines that you can run 50 mi. with the temp gauge reading 250* F, and not damage it. 180 hp and up to 30 mpg hwy, in a car much heavier than any 7.

rotor vs. piston

The series II is supposed to be 200hp even and yes, I'm thinking 30+mpg in 3400lbs car should get me about the same with how I drive, better on long trips.

007, the FI thing does worry me to a point, but I'm sick of the carbed 350 and will be moving that over to FI soon too. It's just a matter of time, skill and of course money. But keep in mind that I got the complete drivetrain, harness and comp. for less than what I see used bare 12a's go for. Mounts will MAYBE be $100 worth of matriel. My biggest single cost will be the rims for the car LOL!!. The other cost will be shop equipment, I plan to by a mig welder soon.

Very nice choice of engine to put in a 7. If I were to do a piston engine swap, it would probably be for the GM 3800 engine. I had an 88 Buick LeSabre that had the series 1 3800 with 165hp and 220 lb ft of torque. Even in a 3600lb car that engine had some "get up and go". The torque is great from them too and the aftermarket is starting to get some parts for the series 2 engines, some parts specifically for the F-Body version. Check out www.3800performance.com. All kinds of parts from camshafts to racing FWD trannies to turbo kits. Don't know if your interested in this stuff, but it may be worth looking at.

o well you guys, just another rotary we can buy and put in our own cars

Kentetsu

LOL, wow man, don't hold back, tell us what you really think! You should express yourself more freely!

Nihilanthic

You find me a rotary thats as robust and reliable as the 3800 (Ive abused one myself) or that could make the same power on boost a 3800 can, and I'll buy it.

And yeah, in this setup.. get the kind of gas mileage a 3800 can get? PUHLEEEEEZE...

cozmo kraemer

I had a 3800 in an F-body and it was the most dead solid reliable car I ever owned. I bought it at 32,000 miles, drove it till 145,000 miles and the only parts I ever replaced were spark plugs and the starter (who says American cars aren't reliable?).

Not to mention the fact I bought the car for $8000 and sold it for $6000 3 years later (still in perfect, near spotless condition)

That engine in a competent chasis would be a great setup!

Keep us updated on the swap

Fixed

rotor vs. piston

Not much new, cut the rotary engine brackets off. The front of the engine sits about dead perfect with the center line of the top of the shocks- so it's still behind the true axle line, yea. The back of the shifter housing sits about 1/2 inch behind the back of the shift hole in the SA, so minor trimming will be needed there. I plan on taking the plunge into a MIG welder this week so I can start fabbing up some brakets.

man , i've seen turbo 3.8 but not an n/a . my friend has an rx7 he just got for free,i sold my red one and my white one isn't running yet , but we talked about the mazda rwd v6 as maybe a fun optional drive train i however have not done research or anything on the 626 rwd engine i think it is...but the 3.8t rx7s are really cool i think.

95PGTR

626's are fwd. if theres any way to orient the KL motors to RWD, please let me know.
