I know first hand that the transmission on an FD is super light compared to a T56 as I was able to pick mine up easily when I installed a new clutch and my friend has a WS6 for the T56 comparison and that is a beast compared to the FD's. However I know the weight difference between the 13BREW and the LS1 is very minimal as I stated in my post before the rotary uses all iron housings so it weighs more then it should for the size. This is why I believe using aluminum housings will seriously help the motors weight and the the change in the stroke length on the 16X might actually mean a rotary that produces torque for once without having to get 3 rotor or even 4 rotor if you're rich.

I'm currently debating whether to drop in an LS1 or not as I've gone through two sets of turbos on my FD in 5k miles but I'm hoping to just sell it as a roller and move on to a more reliable platform.

Dropping an LS1 would be my choice, if I were in your shoes. The FD is a bad @ss looking car. There's SO many kits out there for converting the car over to LS1. Not to mention that the car does 12's in 1/4 with a bone stock N/A LS1! My friend's had a mild heads/cam package and was in the 11's. An LS1 or LS6 would be the way to go. You can still get an LS6 for cheap. Or get an LS1 and put the LS6 heads and cam on. (2001+ LS1s from an F-Body already have the LS6 intake!)

I'm sure the turbos set you back the same cost as an LS1.

Yeah, the T56 is pretty heavy. I had to move a couple of those too. But they're still lighter than the autos... 4L60's are WAY heavier. (Especially before you dump the trans fluid)

WOW something is already wrong with the 370Z! That sucks.

How much did it cost you to rebuild the carburetor? Is the rx7 stock or have you upgraded it?

I got it in 1980 and sold it somewhere around 1992. The carb rebuild was just a kit. I rebuilt it myself. I believe I had somewhere around 130K on it when I sold it. One of the most reliable cars I've ever owned.

I had the 93 rx7 up intil 6 years ago. I can say this much. If mazda goes back to that formula. TT, and the stated 270hp with torque fitting of that horsepower. (Say. 240lbs.) Also if they keep the weight in 3,000 lbs or less. It will be a serious threat to the Z. As it was in 93-96. That rx was a threat to V8's when modded.
Some think saftey regs will keep it heavy. Technology is moving forward. Companies like mazda and toyota are really dedicated to weight reduction moreso than nissan. Toyota said this. If they do produce the FT 86. They can keep it in its weight range and not change the way it looks as the concept. The concept weight is 2866lbs. The concept hp is apprx 220hp 4 banger.
From mazdas history of making lightweight extremely well balanced (true 50/50 weight dist sports cars) I think mazda can achieve this feat. One thing you have tyo remember with rotories. The engines are fairly small, which makes them lighter. What they don't have in size they make up in revs. Fully tuned rotaries may hit 10,000rrpms.
93-96 was the most amazing stock engine of the era. (Though it sucked gas like crazy and drank quarts of oil like humans need water.) But the power, balance, and overall characteristic was like no other car in the price range. The Z of the same era was heavier and not as balanced. (Though the Z was marginally quicker stock)
The only way the new mazda will be a fail is... if they keep the tradition of the renesis and not follow the. Last gen rx7

You know this thread and information is from more than a year back? Shouldnt be in this section either...

:iagree:

I've read one report that it will be based on a miata frame. Teh miata weighes 2400 lbs

Either way its a topic on forum and I'm not the moderator so take up where it should be with one of them.

Either way, the mazda is a car worthy talking about imho. Its nissans true direct competitor and deserves respect. The RX7 was a honda/nissan/toyota owners worst track nightmare in the 90's. Held the world land speed record while the motor was modded and the body was still mostly stock. People have short memories to stuff like this. I want the rx7 back as a
Competitor. The rx8 was crap next to the last gen rx7.

ive seen 300k rx7s before. but most dont make it that far cuz they get modded and nos'd and just totally destroyed by the F&F crowd.

they make their cars all look like this character...

If those stats are correct that would be a damn fun car to drive. Handling would be mind blowing. Hopefully Mazda can keep with it and keep the car light, its time cars start shedding major lbs...

I'm a fan boy of the RX-7, had about 5 of them including a Turbo II. Wonder the price and if the engine is going to be improved especially those APEX seals and heat issues.

Plus the price for the performance. Don't look to bad in the pics.

Are those the sport wheels? LOL

That one is the Touring with the Sport Package and special paint. If you get a scratch the whole car has to be painted and tow to a secret place that only Mazda knows..

I am so with you on a rotary-powered Miata

Those pics are of the upcoming RX-9 which is supposed to be the RX-8's replacement. I have yet to see a photo of the RX-7 other than the concept pics, which look amazing. Don't think I like the RX-9 too much, I still prefer the RX-8 styling.

God that car screams 2000 Camaro Z28
