Oh, and about the gearing, here's a quote from v8rx7.com:
"When I was contemplating my own Hybrid RX-7 conversion, I considered going with a Chevy LT1 with a B/W T-56. I wish I had, because with a T-56 in 6th gear (0.50 ratio) using the same formula above at 80MPH you'll be spinning at about 2,200 RPM's which is a much more comfortable freeway cruising RPM with most V8 engines."

This is Chris V's rex, he got banned from here when he did his V8 conversion. It's not a blower, but this is what a ford 302 conversion will look like.

Yeah, I think what I'm going to miss the most is the higher redline of the rotary. Oh well, at least I'll have the torque I always wanted from an RX7.

If you go with a LS1, they make their power as RPM increases, comparable to the rotary. Redline is 7k stock, and they pull hard all the way to it. The Lt1 has some more low-end grunt, and doesnt pull quite as much up top. Nothing that cant be changed with a nice head/cam setup.

I'm just curious, but since you live in CA, do you plan on making this a smog legal swap? Or are you going to do the whole shady smog technician thing.

That's nice. Does that include exhaust from the block back? Does it include a 6-speed transmission?

If you want to factor in the whole rebate from selling the parts I'm taking out, it'll cost me around $3000, so I think I could do a hell of a lot better than 240 with that "extra" $1000. On top of that I'd have more power available at any given RPM, and I wouldn't have to downshift to make a decisive passing maneuver in traffic. I don't see where your argument is going, and there's no need to be a dick about things.

Oh, and btw, that included a decent transmission, differential, clutch, halfshafts, and driveshaft.

Yes, you can do a TII conversion for as little money as you want, I just said that the V8 conversion was cheaper for what I wanted to do in total.

not to start anything but for the record, i spent 800 dollars on my v8 swap and that includes a 257hp/295tq at the wheels 302 with ported heads, mild cam, intake and carb, new king cobra clutch, and rebuilt t-5 transmission.
i do miss the sound of the rotary though

Some people just want a fast car for the lowest price, and others want a car that has a unique powerplant even if it isn't the easiest way to go fast. I'm one of the latter, but I think that your RXV8 will be awesome. Good luck with it and keep us posted.

is there a kit including any motor mounts and tranny mounts to do the swap?
do the stock headers fit or are custom ones needed?
and if you got an all aluminum 351 and put the battery in the back the weight dist would probably be the same
