You're right, It'll probobly be more like 24-2500 lbs. I have done some wieght reduction, but it isn't a huge priority for me. Like you said, the cars are pretty light already.

I've got BBS rims. They are much lighter than stock.
Ditching the spare tire, lightening the suspension a little.
I'll ditch probobly about half the insulation under the rugs. (a friend took out insultaion, carpet, and sound deadening. About 40 lbs total)
Ditched power steering, cruise, removed LOTS under the hood (emmissions, extra BS),
lightened flywheel
relocate battery, better wieght distribution

It doesn't add up to a ton, but I think 2500 would be pretty easy to obtain.

Did yall run turbo set-ups on the FB?
Hey stylEmon. I ran all kinds of rotary's back in the day. I ran one turbo'ed 2nd gen for a while, 1 PP port, 2 street ports but got tired of the lack of tourque that the rotary failed to produce. What do you plan on doing with your car?

i'm gonna go auto X with this.
I know of a couple 2-rotors that are in the 450-500 range. Mine should be around 320 hp with stock turbo. It isn't too difficult to do with the right turbo, and proper porting/mods.

My buddies 2nd gen smokes BUILT supra's and hangs with bikes.

You can make all the power you need with a turbo rotary. NA is a little tough to really make power tho. Seems like you exoplored that with the PPort! :unibrow:

If you're going to use this for Auto crossing, then a turbo is a bad idea. It takes a bit of time and rpm's to make boost, but when you are slamming on the throttle and brakes in a race, the boost won't have time to materialize. If you're going with straight auto crossing, I would street port it, but if this is going to be a road car, then you can do whatever you want outside of bridge porting and or PP porting, but a turbo rotary is not going to do very well in the auto x races.

If you really know turbos, you realize there is a wide range of variables effecting spool times. I'd agree with you to some degree. A big turbo with a small turnine housing will take a year to spool. There are plenty of variables in the equation, and we've built this motor specifically for this application.

I'll start out slow and let you know how the T2 does on auto x.
Thanks for the comments.

read through this I couldnt help but think that newer cars seem so easy to work on cuz they don't have rust holes.
This is a cool project i have allways liked the RX-7's like yours reminds me of a 944 which I also like the looks of.
Good luck with the project and keep us updated.

stylEmon 03-22-2007 04:54 PM
thanks for the comments. I always think that older cars would be easier to work on because they have HUGE engine bays and less/no electronics! :D

These cars did get some criticis when they came out. people were saying they where too much like the 944s. I definetly dig both cars, but since this is my 2nd Rx7, you can tell which one I like more.

my car prior to my current 64 cutlass was a 95 z28 and changing the spark plugs on that thing was about the hardest automotive task i have ever done it took like 8 hours and no its not cuz i am retarded :) i am currently replacing floorpans and the spark plugs on the camaro were harder. you are right for what you gain in engine space and simplicity you lose with fixing rust and doing bodywork. i guess its just trade offs.
