Rx6?

Do you mean Rx7?

Which generation?

With 250whp, I'm going to guess it's a turbo.

If it's the 3rd gen (93-95) it will do easy 13s with 250whp because it's a 2700lb car.

This is a 3rd gen

A 2nd gen (87-91) will also do 13s but it's a bit heavier.

This is a 2nd gen

I've seen a 253rwhp 2nd gen run 13.4.

If you catch him off boost, you've got him.

If he's on boost, you've got your work cut out for you.

Good Luck!

Yea its a twin turbo RX-6 I'm pretty sure its a 90, so you think i could beat him with just exhaust? i forgot to mention my car is an A4 and I'm not sure if his is stick or not

If it's a twin turbo, it's a '93 thru '95 model Rx7. There was no Rx6.

You're going to need some mods on an LT1 auto to take him. I don't think intake/exhaust will be enough.

If he's a good driver, 13.4 or better possible.

And to get a '93-95 Rx7 to 250whp is extremely easy.

It's possible he may be "sandbagging" about what he has.

i dont think hes sand bagging cuz he just bought the car from a guy who had it recently dyno'd and the current owner wouldnt "sandbag" but hes really cocky about his car and i want to knock him off his high horse

To get that 2nd gen to 250whp he had to do some work.

Intake/exhaust/boost controller/fuel controller and if he didn't get a front mount IC that engine is on borrowed time.

310 is about the max that the stock turbo can make with any reliability at all. At that point it is making more heat than power. With 250 at the wheels, he's at 295 engine.

He might pop his motor giving you the win by default :naughtywa.

That body style encompasses 2 models of 2nd gen.

87-88 and 89-91. The 89-91 has the better turbo and can make the above power.

The '90 model you mentioned will have the good stuff (but bad electronic oil metering pump :sillyme:).

He's probably going to be in the high 13s if he's a decent driver. You might get him out of the hole though because the 2nd gen Rx7 is a pain to launch. Massive differential destroying wheelhop.

I know this is :tmi:, but I used to have the rotary devil in my garage so I know what the rotary addiction is like.

Even though I've lived the dream/nightmare, I still find myself wanting another one.

The lure of the LS1 into Rx7 swap has caught my imagination more than once.

Sounds like you were quite the rotary enthusiast. Can't say I'm a fan, I could never drive a car that makes a Honda 4 cyl look like a torque monster :ughlaugh:

We still don't even know if its an RX-7 for sure...

The Turbos make decent torque (mine made 237 rear wheels on the dyno)

Any car that can break both rear tires loose at the 2nd to 3rd gear shift at 65mph is worthy of some respect.

And the light weight makes handling incredible.

My 2001 SS would take the Rx7 I had 0-60. On the highway, they feel about the same. Handling/cornering the Rx7 would make my SS look like a bull in a china shop.

But the Rx7 is like having a bad girlfriend.

One day all is perfect and you think that there is NO CAR IN THE WORLD that is more fun to drive.

The next day it is a spiteful b***h that you want to push off a cliff.

At what RPM though?? Rotary engines are not know for having any low end power or torque at all.

Any car that can break both rear tires loose at the 2nd to 3rd gear shift at 65mph is worthy of some respect.

That isn't too difficult in a light car with no weight in the back and relatively skinny tires out back. I broke the tires loose going into 4th the other day in my 3500lb T/A with 285/17's out back, damn cold weather.

And the light weight makes handling incredible.

My 2001 SS would take the Rx7 I had 0-60. On the highway, they feel about the same. Handling/cornering the Rx7 would make my SS look like a bull in a china shop.

Does it actually handle that well though?? Or does it just FEEL like it handles that well because its so small and light?? I've driven my friends CRX (~2000lbs) and it feels like a go cart, but the actual handling is neither predictable nor impressive at the limit.

But the Rx7 is like having a bad girlfriend.

The 2nd gen has no bottom end. Not much happens until 2700rpm when the boost hits. The 3rd gen does (sequential turbos, one for low end and one for high end)

The T/A is nose heavy and will break the rears loose more easily. Off idle torque helps too.The Rx7 has near perfect 50/50 weight distribution. Actually like 50.2/49.8. Lots more weight proportionally on the rear tires. And yes, they do handle that well. Drive a 3rd gen and feel what a perfect weight distribution does for handling.

See above. Then check out some of the old track tests of the '93 Rx7. Here's a quick excerpt from one I pulled up..
"Handling in the RX-7 can be a little scary at first, but once the driver adjusts, he is welcomed with one of the best handling sports cars ever made. The steering is sharp and the RX-7 responds instantly to anything the driver throws at it."


Sounds like most Japanese sports cars.

Not really. My MR2 was fun and rock solid reliability. But not near as fun as an Rx7. Ask anyone who has owned an Rx7. most will say the same thing. Absolute fun driving enjoyment. Absolute pain and torture at the rotary gremlins (turbo models. The N/A ones could be quite reliable, but were dogs in acceleration)

Bottom line is I've owned many "enthusiast" cars including a Trans Am, MR2, Mustang GT, Taurus SHO, Contour SVT, and now a Camaro SS. None of them are as much plain out fun to drive as an Rx7. But they all would start every day :cheers:

I'm not really defending the Rx7. I was just giving the guy some tips based on my experience with them.

The 3rd gen especially doesn't need me to defend it. Go try one, if you can find one that is still running. And I can almost guarantee that if it has over 100,000 miles it is on its second or third engine. Rotary gremlins. :brick:

damn it were getting off topic, what would it take for my car (specs mentioned above) for my car to beat it (nitrous not an option im 16 and mom knows what it is)

CJREX
11-13-2007, 08:22 PM
I told you what you needed to beat performance wise.

Mid 13s in the quarter.

There should be a ton of guys on here with LT1s that run that.

This site is LS1 centric but there are still a lot of LT1s here.

See what their mods are and duplicate.

It's gonna take $$$ and nitrous is the cheapest way to get there.

CJREX
11-13-2007, 08:49 PM
Nah, that doesn't sound dumb. It's part of life.

It will simply change one day into "My Wife won't let me do it" :true:

But to the point at hand, I think you'll need at least intake, exhaust, and headers + some sticky tires to use your enormous torque advantage off the line.

Plus, the way an LT1 with exhaust sounds, he might chicken out after hearing it.

Good Luck!

Drag radials.

The Mickey Thompsons have a better reputation than the Nittos but are more expensive.

Only use 'em for draggin' though.

They are soft and will wear VERY quickly if used as a daily driver.

yea i dont have enough money to buy two sets of tires im looking for some good daily driving/sport tires

You don't need 2 sets, only 2 tires and cheap wheels. Don't bother putting skinnies on the front. Not necessary for this whoopin'.

dude, without spending loads of money, your not gonna get that much more. you need tires to hook but unless you want to spend big $$$$ on internals and or F/I you need nitrous, just that simple. or get some really low gears to kick his ass off the line

You'll need to spring for some good rear tires at minimal (do some traction/price research here http://www.tirerack.com/index.jsp?s_kwcid=tirerack|685634413&keyword=tirerack&code=yes&GCID=S13674x009-branded3&), and ensure you've done all the free mods:

get intake and a ported throttle body, with tb bypass, and air foil, and de screen your maf that will give you at least another 30 ponies

11-15-2007, 06:09 AM
there is no way that those mods will net him 30 hp! that wont even get that much on an ls1 which is more responsive to mods. the descreen of the maf will only hurt him

jag42420
11-15-2007, 06:20 AM
The free mods, done correctly, should net you somewhere in the neighborhood of 10-15rwhp, the equivalent of a .1-.15 gain in the quarter. (Maybe 20 at the crank) Definitely worth doing.

No matter what you say about a car if its not 8cyl (wesman) will talk trash about it and pick it to death down to how much PSI you run in the tires, Your basically talking to a trash can with dead bloody bodies in it. I picture (wesman) as an american Hero!!!!

Theres a gen 2 near me with a 20b 3 rotor in it, so lord knows what could be done. 250hp would be about %50 for that car though. Anythings possible, while you're building up to beat him, he could be going faster, too....

I don't think hes got much for top end, but the good thing is the kid is awful driver and his car is a 5 speed so that will definitely hurt him
