A 400HP Rex will blow the doors off of a stock C5. I rode in a streetported Rex w/some other minor upgrades and it was pretty damn impressive. Post the vids!

 

ok best out of 10 runs it is

 

Stock 93 RX-7 0-60 was 4.7-4.9

 

Buy a basic NX kit, take 4-5hrs to put in on, and RACE OVER!!!!!

 

They weren't that quick. I had a '93 and did plenty of research on them. The were low to mid 5 second cars to 60 and they could occasionally run high 13's while most were in the low 14's at about 100 MPH. A stock RX7 will not beat a stock C5. No way, no how.

I got a buddy in town with a nice RX7...

His car does scoot... and he's a driver too... but he's replaced part after part cause of stress and breakage... the motor for a while was in part's twice a month... and now he has three trannies (one in the car and two to swap in... he loves his little scooter though, and it does go.

I read through this thread that a few fellas said to make it best of ten runs... that's a nice number but do an odd number of runs to silence any doubt... that way when you get to driving and end up with better times each lap (road coarse is where you're skills will even out).

Plus I think that if he's got the big ponies you seem to be so apprehensive about, then you want to run a set number of times to let him see what a car that is designed to run will do, and that is the vette.

If you force him to run with you more than once... he's gonna pop something... but if all you're gonna do is the 440 yard dash... you may be forced to eat some crow from your RX7 friend.

 

If the RX-7 really does have 400hp at the crank, he will win pretty easily. That HP puts him in the flat 4 sec 0-60 and low 12 1/4 bracket. The car is lighter, has shorter gears to climb (5-spd) and rev faster. This is of course if he knows what he is doing and has the meat in the rear to get some traction.

That being said, a stock rx-7 could not beat a stock c-5. Rx-7 stock times at best are low 5's 0-60 and high 13's/low 14's in the quarter. To whoever said RX-7's are all rice I would have to disagree. It is quite a very nimble, light, designed sports car from the ground up. A far cry from Hondas and Toyota econoboxes that people buy large exhaust tips and put stickers all over.

 

I have a tremendous memory (and can back it up with an even more tremendous collection of car magazines going back 39 years!). Also, my very first car 30 years ago was a rotary engine Mazda. I've owned 7 Mazda's, two of them RX-7's, one with an aftermarket turbo (previous to the factory turbo cars). I can assure you the numbers in the quote above are accurate.

Both of the C5's I've owned with just a cold air intake, and cat back exhaust have consistently run 12.6s - 12.8s at 112mph. That's with me driving - and I never drag raced at a track until I was 48 years old.

 

 

That was the exact spec quoted by Mazda, what it actually runs 0-60, who knows? Does anyone actually measure 0-60, other than magazines? I hope not, its a useless statistic.

 

I definitely need to proof-read my posts before hitting submit. I accidently hit the 3-key instead of the 4-key --- as in 4.8 on 0-60. Sorry for the error -- at least it got some from a few of you.
(I know it made me chuckle when I got home tonite).

 

i was on a road coarse ana 450 Hp Rx7 got me in a straight every time but in corners a

after the race the Mazda owner was joking my car and sain ma next car will be a vette

 

Stock RX7's were in the low 5 second range....all the 90's RX7, 300Z, Supra's were in the low 5's. My friends RX7 was a little faster then my 300Z.....and my 300Z is nothing compared to my Z06.

The May issue of Sports Car International (bought it for a article on Z06vsGT3vsEVO RS) had a article on affordable sports cars and futured the RX7. States the low 5's. Affordable for people to get and mod.....but everyone I know that puts $$ into mods kill the motors or trans in short time. Don't see many since only about 15,000 were sold in the US of the 3rd gen RX7.

Went to Rotory Rockets open house which was between warehouses, perfect spot so races were going on......saw a plus 400HP RX7 get killed by a Skyline. Wish I drove my Z06, instead of the 300Z that day

 

I had a heavily modified '93 Rx7. The stock Rx7 was no match for the vettes, but the Rx7 was a real sleeper. She looked pretty much stock on the outside, but under the hood, she breathed fire.
I had a single turbo conversion. Single turbo in it was a custom built Garret brand turbo that is a little bigger than a Greddy T78 but it is better because it has a smaller Turbine wheel which allowed the turbo to spool up quicker releasing the power quicker like a smaller turbo which helps it cut back on turbo lag. Cooling the turbo is a huge 4.5 inch wide Greddy Intercooler, an Aluminum AST, Apex Turbo Timer, Apexi blow off valve, 1300 cc Secondary injectors, 850 primary injectors, Greddy Cat Back Exhaust, Greddy Pulley Kit, Polished Strut Tower Brace, High Pressure racing fuel pump, Hoses were Silicon Hoses to handle high psi levels, 9.5lb flywheel, cross drilled rotors with carbon pads. Untuned she pushed 365 hp to the rear wheels at 12psi. This monster tuned properly was capable of running all day long at 15psi and run at 425+ hp to the rear wheels.
If your friend has put some heavy duty mods on, you may want to think about adding a few more mods on your vette before going to the track.

 

stock RX7s r pretty much in line w/ an LT1 vette, performance-wise. a stock c5 should be able to take it (stock for stock), but if that thing has 400hp...forget it.

 

I said hello to one on an empty freeway once - It was a Vin Diesel looking car- and I pulled on him right away, and I should have gone a gear lower. It was much closer than I would have guessed (maybe because I grabbed the wrong gear?). I don't know what was done to that particular car, but I will say they have my respect.

At that time, I only had an airbox, headers and exhaust- and no clue what he had done.

 

yeah, i know what u mean. i think that stock they arent the high and mighty car that some people think they are. like i said, a stock c5 should be able to edge one out in most cases. but they can be made insanely fast. when u run into a "vin diesel look-alike", u never know what u r getting. sometimes its all appearance and other times they have some serious motor work. in any case they r respectable cars, i actually somewhat considered one when i was looking at c4s. but i heard they have a history of the engines grenading. plus, the vette isnt just a car, its a lifestyle in a way.

 

Trash talking aside, just go see what each will do. Regardless of the outcome, the track time will be fun.

 

RX7 would walk it. . they only weight 2800lbs.
