Calling all 13 second cars!!!!!
I seriously doubt whether a 200hp RX-7 wll get you into the 13 seconds.
Depending on how much weight has ben stripped out, the most likely performance range is 14.5 to 14.8 seconds. To get to sub 14 seconds needs 250-270 hp and good tires.
The real question is how to get to 270hp cheaply and reliably. A 12A will need so many modifications there will be a lose of its streetablity. A 13B offers more options, a TII could do it with some moderate modifications, but the optimal way would be an exCosmo 13B REW reverting back to a single turbo. A budget of $7,000 should be planned to include everythng necessary from the fuel pump to the tires.

that's what I'm doing but with a weber DCOE.

No runs 12 miles before something needs to be fixed on the POS. FC's are junk... Campaired the interior quality and such of a FB.

Hell screw the 13s, and put your money into your suspension and make it corner, what the hell does it matter how fast your car is in the 1/4 if your cant drive it??
ahh the power of g forces

Nice blanket statement. My 1991 TII is a better build and better interior quality than my 1983 GSL. But hey, everyone has their opinions...

Example: 1991 Lemans winner, Mazda 787B, 4 rotor peripheral port. Sustained 8000RPM+ for 24 hours at very high speed.
I think it lasted more than 40 miles.

Peripheral ports are reliable. It's just that the rev range requires carbon seals which tend to wear quicker than steals. With an occasional freshen up of the apex seals they can last a very long time.

This car has over 200 passes at the 1/4 mile. Peripheral port 13B. Runs high 10's / low 11's consistently. The motor could go another year easily without needing a rebuild. Peripherals are more reliable than monster or "J" ports that go into the waterjacket.
By the way, the car is completely street legal, with a full interior. He drives it on the street several times a month.
Hey I got a 13B 6 port that I'm porting just to mess with it...I hate 6 ports.
I currently finished the streetporting on a sweet 12a it's a nice extended port (TODAY!). I'm buying the nitrous setup in a month, I'm racing next year on a road circuit with my 85 black GSL with that same engine I'm building, and I want to go turbo for drag on a GSL-SE but that's another story, it all depends on how my first project goes along and how much power the LT1 with supercharger that I'm building for one of my clients runs...if it gets over 500hp I will have to match it
I'm one of the ones doing the stuff I'm talking about...About dreaming it's all fun...

um..
i forgot the website but it was a site for a race shop. on theyr web site it showed a gsl-se with rebuilt motor and dellorto perfectly tuned. it ran 13.9 with street tires.
it is all about tuning. some ppl like to spend 300 bux on some rice rocket exhaust but id rather spend that money on a dyno and get my car tuned in perfectly. from the muffler ull prob get 5 horse power, more noise and more tickets. after spending time on the dyno ull probly get upto 10 to 15 more hp depending on the condition of the car. and still quite.
remember. elevation counts alot. some guys might say they only ran mid 14s with a bridge port but they may be going mid 13s at sea level. cant forget about the weather temp either. when i raced at palmdale durring a hot summer day, i ran mid 15s but after the sun went down it started to get a lil chilly. at night, i ran 15.1. palmdale is also higher elevation so the time u get is approximately half a second slower than at sea level. if i ran 15.1 then it means my car is actually around 14.6. have a gsl-se with dellorto setup. my tranny grinds and my clutch slips sometimes and my tires r almost bald so if i get a better tranny, a new clutch and some new tires i should be around 14 flat so going 13.9 with dellorto setup on a gsl-se seems believable.
driving skills counts alot too.

also...
also............... if ur car goes around mid 15s and 14s, u should stop worrying about speed and make ur car corner. get that car to corner and hit up some autocross or speedtrials. its alot more fun than going straight.

Well I can say I can runs 10's all day long on street tires, and if someone beleives me its all good... Personally unless I see it, or see the time slip then Im hesitant to beleive it, well thats if its hard to believe sortta thing
Hey Mike, I'm hitting chandler saturday to see what the little frankenstien will run on the crap street tires. You should drive it over and make some passes. I can get you home if something breaks.
