since most of that was pretty much greek to me i'd love it if you could link me to the writeup. i'm still learning how the rotary works. i understand the basics but when you get into the detailed stuff i get lost. thanks man.

I think almost every contest since then it's been some V8 monstrosity.

Actually, the slowest V-8 still beat the fastest rotary on the autocross section of the competition. Honestly, if you want to be competitive, you'll need to go with the V-8.

And the biggest part of autocross has always been the driver, so practice up.

I absolutely HATE putting v8 in a rotary car, but in your case you may have to...even with nitrous oxide and a few support mods you wont break into 13s. Also rebuilding your engine isn't excatly cheap either. I would take kyb agx over koni yellows though. I have them on my car and they are more for track use than daily driving I can tell you that. Also bushings are a must.

believe me, i do pratice. you get a bit different feel while driving an AWD torque monster though. i wont really know how i'm gonna react until i get behind the wheel of an FR car. i've driven several subies, two P5's and a couple franken civics but never a FR car in a auto-x. this is only my second year with my local club and i'm still learning how to become a better driver. even if i take the car out an dont win, i've always got next year...and the year after that...and the year after that....ect.

i have AGX on my Impreza RS as well and i love them, but i think koni's my be a better choice only because of the broad range you have to adjust them.

i dont care how much time i lose here but i'm not putting a V8 in the car, period. i will not disgrace the RX-7 name by putting some hyped up american engine in it. plus, now i get to show you guys that a N/A rotary can compete in this event!

make stuff yourself-its cheaper and you can get it to look nice. you can make vented headlight covers pretty much for free(use the one off the car + bondo or fiberglass)and that will work for the show car part. depending on your access to tools/materials, this could really help your budget!!

If you are looking for forced inductions I remember a Grassroots magazine article a couple of years ago that used an electric leaf blower as a supercharger on a BMW. I was like WTF but the damn thing boosted around 15psi if I remember right. Just another option

i agree with reted. a 150 shot of nitrous in a totally gutted streetported NA will get to you nearly 300whp which is plenty for 12's in a 2500lb car.

you're gonna spend atleast 500 bucks on the rebuild so thats gonna lave you with about 1500 bucks to get tires, springs/shocks, nitrous, a clutch, etc. not including the money you'd get from selling parts, spoiler, sunroof assy, etc. so selling that stuff might be able to get you some tires or a clutch.

if you look into forced induction though, get an ss autochrome turbo they have been known to crack I think, but it should last a few months of racing :P

ok, well just a quick update. picked up another motor and tranny with a blown rotor last night (freebie!!) and i'm still tossing the idea of the rebuild vs. the V8. i already have the V8 motor lined up (chevy 283 4 bolt) so that's an idea. the car is gutted and i'm getting ready to start selling parts to recoupe some of the cash. the real work is gonna start in april when my garage is finished. figured i'd fill you in.

Spend a lot of time on the concours part of the project - for many of the competitors, that's where they leave a lot of points on the table.

Last year's winner was fast, but also looked amazing. What really brought it home was that it looked like the motor swap looked like it came from the factory that way and then let the car sit in their garage for a couple of decades. The Nissan "343" project was the same thing.

well, kinda. i came to the harsh reality that i will never win the drag competition with the budget i have on the 13b. i think what i'm gonna do is put the 283 with a 4 barrel webber and a 200 shot in for the challenge. after that i'm gonna pull the motor and tranny setup and sell it as a kit and put the 13b back in before it becomes a dedicated track car. a V8 swap would really screw up my classing in SCCA and NASA. who knows what will happen though. if i can come across a good carb setup for the 13b for really cheap then i just may go that way. it's all up in the air right now.

Just to chime in, The Megasquirt is an awesome EMS, especially for a challange like this. I ran it on my car for all of last autoX season, and I loved it.. I can't wait to see how it does with boost this season

A stock 283 SBC is a piece of crap. At least put a 350 or a ford 302 in it. Not to be a dick but you're probably not going to win the challenge so why not put something together that you like (a rotary if it's your cup of tea) have fun competing and then have a car you want when you're done.

dude, do a cheapo rotary rebuild, buy a used nitrous kit and get a 150 shot jet. also get a megasquirt&spark ECU, fuel pump, some used bigger secondary injectors and you're golden.

seriously.

If you've got 2 blown s4 na motors, you have enough parts to make it run with about $50 in soft seals.
Maybe you can streetport it while it's apart?

Nitrous + 13b = fast! I'd spend your money on the best used wet nitrous kit that you can get ahold of. I see no reason why you can't be in the 12's easily.

Get a pair of drag slicks if possible, and buy some roadcourse slicks too for the autox/show.
If your stock suspension is in good order, leave it alone, the stock FC suspension is no slouch.
Gut it! Paint it if the paint sucks!

megasquirt seems like a good idea too. Make sure it's reliable.

well, help me figure out exactly what will work and then maybe you can . i just have very very limited knowledge of the 13b and how to get power out of it.

and btw, i was using a 283 because i got the motor for $50.

you could beg and beg someone in possesion of a 26 b rotary engine to let you have it for $1500 or something. haha not gonnahappen but you'd (I wanna say win but that's skill dependant) but your odds would increase.
