Hello,

I had an 83 GSL back when I was in school and I LOVED it. Unfortunately, it died and was sold to Maz-max in Houston for parts.

Now, over ten years later, I am itching to get back into a rex. I have a lead on a supposedly "clean" GSL-SE, I am just waiting for pics and a time to go see the car from the owner.

I have a cts-v, expedition, and a truck to handle all the daily activities. I am really wanting a toy. Something raw, loud, low, barely legal, and fun. My original idea was a bridgeport or p-port n/a, but the more I read, the more I am leaning towards a large streetport and lots-o-boost. I dont care about driveability...at all, this car will serve NO practical function, other than my own personal satisfaction and ticket collecting. lol.

A ton of what I am reading online seems to be information from the early 2000s....almost like the rotary following had slowed down. I hope this isnt the case.

I am sure that I will have tons of questions and ideas as this evolves. I just wanted to say hello to my fellow FB folk, and put some of my thoughts on paper.

Please feel free to toss out ideas and opinions....I have set nothing in concrete....except that I want another FB.

 

35 views and no comments....geez...do I stink or something? LOL

 

Just your thread presentation and well its the weekdays everyones working lol.

 

Hope I didnt come off as a DB. Wasn't my intent. I am really excited to get back into a Mazda and try my hand at engine building. I've worked on a ton of cars, but I've never built an engine myself.

I also race Off-road RC, and those guys talk endlessly during the week, but the forum is silent on the weekends (everyone is at the track. lol)

No biggie!

 

There's a ton of information on this forum. I'm sure overall ownership has declined over the last 14 years since the 2000's just from the engines dying and people scraping them. Just like any "car club/fourm", Mazda rotaries have their long-term enthusiast and the "new guy." Welcome back to the club. There are many knowledgeable folks here that can help.

 

Then it just might be what i notice sometimes. Weekdays sometimes seem pretty slow but weekends ppl are power fixing there sevens. like me i get 1 day off a week so i usually only get saturday to get anything fixed up and ready for next week.

Man do i really wanna get out of town lol a bunch of rotary owners in boise and i just cant get the time to meet up with them lol. Dx

Not so much coming off like a DB more just like a really excited teen hoping to make a race car. But its rotary who doesnt wanna go faster in one? As for boost i share your excitment for the day i can build and cram more air into my engine.

 

There is some truth to this. I wanted to do so much to my rx7 back then, but I was in school and had zero funds. Now, I have a good job, a family, a house, and a some cash I can allocate to the porject.

This is by no means will be a big budget overnight professional build, but hopefully I can take my time and build something noteworthy and fun.

Maybe I can get a peek at the car this weekend...if so, I'll post some pics.

 

My thoughts, stick with your bridgeport or PP idea and go weber downdraft 2bl

Itll be the craziest sound a car ever made, and everyone will think they hear a street bike coming. Plus, they are durable and take a lot of abuse.

But the real reason to go NA is for the RPM's... nothing says toy like 8500 rpm shift points.

You dont need all the complication turbos bring to have a lot of fun. I have a 12AT project just sitting around because I cant really see myself driving it. I have had NA 6 port 13b's and 12A's (all carbs) that pretty much do everything I want them to do.

And if youre really crazy you could make your motor a half bridge and use a 4bbl carb to stage the induction so its nice and tame on the street, but ***** out when your foot is in it. That and a 150 shot of NOS (really easy to do with a 4bbl) will probably literally scare you of driving it, which makes it all the more fun.

 

You just described the next 12A I want to build for my 7. Keep out of the secondaries
and get reasonable mileage all day long. Stick your foot in it and grab the wheel!

 

You'll find a half bridge is more difficult to start than what you're used to, and the idle will brap. This is due to the secondary bridge allowing exhaust gasses to circulate a bit.

 

Here is my hang up with the n/a....the dyno #s.

Maybe im comparing apples to oranges, but I drive a 400HP Cadillac CTS-V everyday. Its 6spd, all aluminum v8 motor, but bone stock. It moves good, but its not scarry crazy, or exciting.

I keep seeing that a WELL tuned P-Port will make 300ish hp...just seems like Id be less than impressed.

Maybe im over simplifying the comparison, or missing some wildly important information.... I am just afraid to spend thousands getting a carb'd p-port going and wish that I had more HP.

 

Then go turbo with stock ports instead. It's pretty impressive.

 

I was kinda hoping one of you would convince me that 300hp from a p-port in a rx7 would be way different and much more "exciting" than my 400hp daily.....

I do like the idea of being able to say that I have a street driven p-port....But those turbos sound so killer, and look awesome when you pop the hood!

Im conflicted....and rather bored at work!



edit: and sounding rather childish today....oh well.

 

Considering the Caddy weighs a lot more than a 7, I think 300 hp in a 7 will
be pretty, um, scary.

 

Exactly!

 

Your caddy weighs like 4200 right? A RX-7 weighs about 2200-2400 depending on what you have done to it. 300-400 horsepower in a RX7 is insane. F=m*a and all.

 

one thing I can tell you porkchop is you only get one chance at porting so pick a style cause all the different types of ports bring some kind of outrageous fun depending on how you do it.

I know for a fact once I find a spare motor im probably gonna do a bridge port to it and run it all N/A and just scare off all the little honda noobs on my way to work. ( lots of them in Idaho cheap and affordable cars but annoying as crap when all they do is intake and exhaust!~)

also the ultimate goal is for it to start brapping in my opinion lol

cause there is nothing that sounds more sweet then a finely done bridge with a sweet brap on Idle and an aggressive acceleration!~ :P

 

Look up 74 spec. Add turbo. Win.

 

totally not exciting...

 

Longetivity i say go with a large streetport. More fun go with a 4port full bridge; however, for street use, you wont feel the power until above 5k rpm so its BORING. I daily drive my RX-3 with 13-B bridge/52mm IDA say at least twice a week to work at downtown LA. I got tired of it so i started playing with gears: 3.90 4.44 4.78 4.88. Now i settled with a 4.44, fun on the street but not so much on the freeway (top end) but its a matter of preference. Besides, changing 3rd member to taller gears doesnt take too much time.

And believe me, most ricers wont even make eye contact with me as they know what it is.

 

Lol when I had my 2nd gen still I raced 4 Honda's that had ported heads exhaust and intake and I beT them all stock rebuilt motor and just all8k rpm from first gear to 2nd gear only lost once to an actual built Honda but it was whatever. But even now Honda's won't race me in general because they know my first gen is rotary and because I'm a crazy driver.

Ps Mazda speed 3s try to race me all the time but out of respect I guess must me a same brand name thing?

 

Nobody races my FB because of the track radials.

 

I don't have track radials but I do have treaded radials that look pretty mean on my 13s lol.

 

Rob, I feel you! Except I kept mine all these years and am now giving it away
