But a lighter and more powerful car over all. For example my friend is making a NA 3 rotor (most rx7s are 2 rotors, aka 2 cyclinder, and there are less then 25 3 rotors in the US) that will make about 400HP with a 9-10K rpm redline. and his 400HP estimate was with a 8500rpm redline, with a bigger port he could hold his tourqe in the higher rpms and gain alot of HP. Try that in a Max!!

don't waste your time.
VGs are cheap and easy to work on.
the rotary is neither of the two.
if you want power and know how to do it, then you won't be on here asking for opinions... do it, THEN post pics.

Rotarys are great for racing, but as a daily driver I'll pass

I can ask the guy I know down in Oregon if he wants to sell his spare if you want.

Rotary's have one common flaw, no matter which engine you get. The coolant/oil seal goes out often. Plus the was also a problem of fuel management on them. Which is supposedly fixed with the new RX8 engine.
Nice thing is... they're a lot easier to pull out than our VG's, and the RPM range is just nuts. Plus the fact it's lighter, and adds a lower center of gravity.
But if you just want a lower center... throw in Subaru's boxer engine.

The original production model had great problems in the NSU Printz, seals leaking like a bulldogie. And the piston is kinda hard to cool; at least attaching cooling hoses into it is somewhat complicaTed...

70sss LOL. More like .40 cents during that time frame 
It was .50 cents when my parents where over in germany in the early 80s.
That's ok, Nike bought their symbol for $6.
Oh... and they're called rotors, not pistons. The engine was a great concept, now if they could fix the leaking coolant/oil seals.

from what i hear the VQ is actually lighter than the 13B.
i have a 13B 4-port normally aspirate (yup... the very rare one). i don't look forward to fixing it though. if i had to ever replace a rotor that'd be overly expensive. i'm tempted to just toss the VG into the truck for some more low end torque.

I would admit I'd like to see such a conversion. It's too bad the rotary is so iffy on reliability, because it is perhaps the most interesting engine design I've ever seen. Besides the design, the thing I found so interesting about the last RX-7 was how much power it got out of 1.3 litres and two turbos. If the RX-7 was a more reliable car, I'd wager they'd be more sought-after than Supras at this point.
Chevy really only toyed with the rotary idea in the 70s, building a Corvette concept that never made it off the ground. Like the 4-door Vette, the Rotary Vette is lost to history...thank God.

they also built a monster sized rotary for a truck. it made quite a bit of power and was huge as well. they are definitely interesting engines. they can be 100k+ mile engines, you just have to take of them properly and use quality oil as they basically run like 2 stroke engines. (so much so that you can run them on mixed gas if you disable the oil injection system).
what'd be nice about an engine swap like the rotary is the large chance you could find a different transmission that actually doesn't break only 160 hp. (i'm going to make a song entitled **** borg warner some day).

I'm going to have to get in on this thread since I bought an Rx-7 over the winter to mess with a rotary motor...
Rotary engines have a bad rep. They arent as unreliable as people make them out to be... hell my rx-7 had 20psi on all 3 faces in the front rotor and 15psi on all 3 faces in the rear (90-120psi is good-great) and it started with no problems(just had no power). Also, Mazda uses the rotary motors in their race cars (star series or something like that) and they only need to be rebuilt like once a season instead of after every race. They also arent that hard to work on...
You probably wouldnt want to put this in a maxima because it lacks torque(some one said that before) and they are expensive to fix... I have to order all the seals to put my engine back together and it going to run about $700-800(which is not unreasonalbe for any engine rebuild) but if any of my rotors or housing were damaged it could have gotten really expensive really fast! I thought of putting my spare VE in the rx if my engine was trashed and couldnt be rebuilt...

put a Ve in an rx-7? wtf? I have a 93 R1 shell....and I'm going to do a hinson ls1 conversion..why put a 190HP engine into a 2700lbs car when you could put a 400 hp/torgue v8 from a corvette into it?..did I mention the 6 speed T-56 tranny?

92se- Ive seen many of the internal parts of a 2 rotor bc my friend that works at the hobby store i work at loves them, its all hes owned. I even helped him start tearing down his 3rotor when he first got it. it was sweet. If i did get a rotary (which im not, this thread was just to ask if any one has done it..) he would be able to get me cheap parts and he could help me alot.

This is quite a common conversion. torquecentral.com has all of you info on this swap. The only problem is that the cost is like 10k (it's a little lower but most people say that much).

Well with the companies making kits to fit the engine and help with the cooling/electrical, it's about as easy as something like this is going to get. It IS fairly common in the swap world. Not something a newbie could do, but a well versed diy'er could do it.
But the 400hp LS1 and T56 will probably run someone $4000-ish plus a few grand for the conversion kit. So yeah, $10 grand sounds about right.

The VE isn't really a good choice IMHO. For all the CUSTOM work you have to do to get running, you only end up with 190hp. That's 65 less hp than a stock FD3. If you want to do a swap cheap, look for a LT1 or a carb'd 350 like you mention. A stock 5.0 out of a Lincoln put a 1st gen rx7 into the 12s. Not bad.

I want to hear the adventures and see the pics.dude they even mass produce the engine subframe for the ls1 that will fit the rx7 the expensive part is buying the engine/tranny...everything else is in the ball park of $2500-$6000
I'm doing this swap, because I've watched someone do theirs and it was pretty much straight forward..all the parts were supplied by granny speedshop or hinsonsupercars.com..he sold his 13b twin turbo engine for 4k...bought an ls1/t56 tranny on ebay for $2500, engine subframe $900 and spend like $2000 or so more on miscelaneous parts, since he has his own garage and has been working on cars 4 ever...people who spend 8 and 10 k are those who opt for hinson to do there cars..they do it professionally for 8 grand.
there is even a guy at wrongmotor.com who does one or two 2nd gen's for free every year as a hobby, he was one of the 1st to do this conversion.
As long as you supply him with the engine/parts.
why would anyone want to put a DOHC ve in an rx-7 I dont know..albeit it being a leighter car ( 2700 lbs ), but the ls1 is a prove engine..with alot of mods available..hell throw some cams onto it and u're running 12's..could you imagine what a turbo ls1rx7 would be like?...rx7's can be had for $3000 rolling chassis..which is all you'd need..thats how I bought mine, as a rolling chassis for $3500 on rx7club.com..came with interior, suspension...only thing missing was the engine/tranny..which I dont need anyway, rotary engine cost alot to rebuild...and give poor gas mileage..but they have the sweetest sound in combination with the turbo/blow off valve.
**** **** wankkkkkkkkkkkkkkkkkkkkkkk..lol

I just like to see action and not only words.
FYI, the rx has been sitting in a garage for 1.5 years now

i'm most likely putting my turbo vg into the rotary pickup that i have. 2300 lbs + turbo vg = kickass
i may supercharge it down the road... but then again i might not. it'll be fun either way though and should be quite fast.
(talk about off topic... )
