RX7 with what engine?
An RX7 came along with our wednesday crew tonight (i'll have some video for you guys in another thread later!).
And everyone crowded under his hood to see:
A 2001 Camaro SS LS1 engine crammed in there. He pulled out the rotary engine from his last gen RX7 and swapped in the LS1 tranny, engine, and ECU. Amazingly it only weighed 30 pounds more than the RX7 equipment he pulled out. And considering how much lighter this car is vs the Camaro, this **** FLIES. I think he said he dyno'ed at 350whp so far.

If he pulled the 13B out of an FD, someone needs to shoot that dumbass. The rotaries are perfect engines IMO.

he had so many problems with the rotary he finally gave up on it and swapped the LS1.
I have video of it i will post tonight. No video of him driving really, but some video of the car.

For the motor to be any kind of reliable, I've heard of guys getting them cryo treated and everything. Spending big bucks on them. Honestly though, I definately think it's worth it.

why would anyone remove a rotary for a V8?
thats stupid.
he should have gotten a 4 rotor using 13B parts, or a 20B and boosted the hell out of them. a stock rotary takes alot of boost and makes alot of horsepower very easily.

becasuse the LS1 is lighter (the 30 lbs comes fron the tranny, a T56 is a big boy), more efficient (he'll double his gas mileage), and they have TORQUE. Stroll over to hinsonsupercars.com They do these swaps all of the time, and I have to tell you, I'd do it in a heartbeat. I can't imagine having over 300WHP in that chassis. Do heads and cam (kinda the LS1 equivalent of our I/H/E) and you have way over 400WHP. They are very responsive, high tech motors, not the carbed iron-block V8s of yore.

Haha, in all seriousness, this is a common swap. The 13B-REW rats nest twin turbo setup caused very high heat, especially in the earlier FD's. Reason being is that the cooling system was poorly designed. Rotaries run very hot, and with the additional heat from the turbos, this caused some serious overheating. Most rotor heads in the know will upgrade the cooling system from the get-go, and some have switched to a single turbo setup. Today's ball bearing turbo setups deliver equal results as the sequential twins in the FD's without all the extra heat. In 1999, the Japanese FD's were redesigned with a better turbo and cooling setup.
Turbos plus rotaries aren't exactly the most reliable, although they make power like crazy. Any slight hint of detonation, and apex seals are blown. However, a properly maintained turbo rotary can last over 100k without a rebuild.
Alot of guys get sick of all this, and just throw the LS1 in there. Now I can't remember the exact website, but these heretics have their own forum for themselves. It's kinda cool I suppose, but it just doesn't seem right to me. Rotaries are built by hand and very few cars on the road have them. Light weight, and compact enough to fit behind the front axle so as to make the car almost mid engined. Granted the LS1 is only 30 pounds more, the weight distribution is all off now, because of its volume. The engine is too big to fit behind the front axle, and the car has now lost its 50/50.
For drag racers, more power to em I suppose. More reliable, easy power. The 13B could make as much power, but probably wouldn't be very streetable. For auto crossers, canyon carvers, and road racers, they usually prefer the more balanced car.

theres nothing wrong with a v8, especially if it weighs less than the rotary. and he can get A LOT of HP out of that motor. its not stupid at all, just different.

wow, never heard of that swap before.....ive driven an 02 ss and cant even imagine what that motor does in that little car
4 cyclinders down, 4 to go.....

go to project H7 and then video page. Look at the twin turbo teaser video. The only thing different about that car and the 1200HP supras is about 700lbs, and enough torque to change the direction of the earth. See if that little lawn mower motor looks so cool anymore....

in an upcoming issue of Sport Compact car, a guy shoved a LS1 in his rx-7, fully built motor, and nitrous.. hes pushing 430 at the wheels with about 350 lb-ft of torque (without nitrous). i was crusing behind him on the freeway when he punched it and made the tail wiggle a bit.. thats from at least 70mph... i dont thing a built rotary can do that.

BTW the "sandwiched" 4 rotor engines are quite simple. All rotaries are basically put together like a sandwich anyways, and all you would require is an elongated eccentric shaft. It's quite common somewhere in the southeast...more common than you realize anyways...
2 13B's = 2.6L rotary. It's volumetric efficiency (not volume) is equivalent to nearly 8L. Don't think that'll make your tail wiggle?
in the end, its all about handling when u want to buy a jap car isnt it? isnt that why we all want evo's? sti's? s2000's? the list could go on but bottom line is, people want jap cars not only for the reliability but handling also

it was a road car. with 18in. 3 piece ccw's, huge AP racing brakes, ground control coilovers, huge sway bars and strut bars.. very nice stuff.. he blew off his headlight cover going 140mph on the track.. his weight distribution was 49.5/50.5.
