88 rx7 se nt vs. 01 civic si with rsx engine/tranny

I want to win this race from dead stop to any roll. I need the help of the rx7 gods. Here is what i am doing thus far:
89-91 intake manifold
racing beat header with presilencer, no cat, with greddy exhaust
underdrive pulleys
electric fan(whoopedy doo)
4.30 ring and pinion
fidanza flywheel with act clutch

I want to also remove anything emissions wise, remember this is a daily driver but i don't care about gas mileage. I don't want to do peripheral port or bridge or carbuerate through rb(nothing internal). i do wanna keep a/c and power steering(daily driver).

I want to put this fwd foreign geo metro in its place, lol. On a side note, why are there less rwd new cars, is it the cost?

Skip the pulleys/e-fan. Gut your car (carpet, passenger seat, spare, possibly everything, etc.). Go single exit exhaust. Consider swapping to a 13BT and/or nitrous.

Removing the air pump will result in your auxiliary ports not working anymore. You will have notably less power in the higher rev's, which i'm assuming you'll be needing if you're drag racing (which i'm also assuming). Removing the cats will also do the same thing. You'll need to rig up some sort of electrical switching system as described on the rotaryresurrection website. I'm guessing you have an S4 since you wouldn't swap an S5 throttlebody/vdi/manifold onto a S5 unless it was broken.

Or, you could remove them altogether which would lower your below 4000 rpm horsepower. I'd say it's about a 10-15 hp loss.

Alternatively, learn about driving. Beef up your suspension/tires. Do a general intake/header/exhaust. Challenge said FWD to a nice stint on the track. Enjoy watching them struggle in your rear view.

Don't hit or kill anyone on a public road. Please.

There are quite a few RWD cars in production (350Z, G35, S2000, 300, Charger, Mustang, RX-8, etc). I don't fully understand the question. Less than a few years ago? A few years ago we had Supra's, 3rd gen RX-7's, Camaro's, Transam's etc...

I think he's thinking of cheaper rwd production cars.

Like now, you can get FC's and AE86's for less than 3k all day...

So put that into perspective with a brand new car...

I think he's thinking of a brand new RWD tuner car for less than, say, 14k.

I agree. If the swap was done right then it should be a high 13 to low 14 second car and most N/A RX7's are in the 15-16's.



I have a buddy with an RSX and he is running low 13's N/A.



If you serious about beating him. Then about the only options I can think off is getting a turbo swap, buying a turbo car and mod it.




Wet nitrous kit with some drag radials/slicks and only going from a dig would probably do the trick also.

He is going to take you in the straight away.
Now with an upgraded suspension, LSD, performance tires and/or wider rims you'll be able to take him on a course anyday.

Bridgeport standalone and custom intake manifold with cold air, gutted car with 5.11:1 gears and kaaz lsd.

Get some 225 wide hankook RS-2s or Falken azenis, you'd win.

The 350Z, G35, and RX-8 would fall into the class I'm talking about. The others would be considered muscle and/or luxury sedans with hp. Why couldn't mazda make the mazda3 and/or mazda6 rwd? Why is the srt4, cobalt, compact sports cars all fwd?

Well it all depends on what you are willing to do to it and how long you have to do it. Unless you are harry potter and can wave a magic wand and make the car run faster you will need serious modifications to beat that car. Fortunatly for you, you have a good chance of beating him off the line. The best thing you should do is make sure the engine is running right. Check compression, air/fuel ratio, bad sensors, etc. and go from there.

Your only chance at beating him, short of major internal work or a turbo, is nitrous. thats it. No chance otherwise. Look in the FAQ for the nitrous thread, or search it. thats honestly the only chance you have. And then when you do beat him he is going to hold the fact that you used Nitrous over your head. "If you didnt have NAWS (thats what he'll call it) then you wouldnt stand a chance" and he is right.

It would not be that hard to beat. I beat my friends 87 Supra turbo with a k&n cone filter and the exhaust pretty much cut off after the downpipe.

It won't be a win by a mile, though.

I bought a car off a forum member here and it was completely gutted with no interior to speak off, no ps, ac, wipers, speakers and a rebuilt motor. It spanked on just about everything. Fords, Honda's, Toyota's, Nissan's and etc. I wasn't even trying that hard. Go out to an abandoned parking lot and practice your launching. Have a friend time you on a deserted road if possible and find out your weak area's.

Ummm, yea, were they aware that they were being "raced"?

It's a 146hp car, it's not going to be that fast without a lot of work. With a good launch you can get a bit of a head start to begin with, but you're racing a not so heavy car with 200hp.

I'd agree that NOS is the only practical inexpensive easy solution to being faster.

why does everyone care about "beating" some new car with their worn out 20 year old car?? ... who gives a flipping ****. The RSX motor is better than an NA 13b... 20 more years of technology. a v6 engine from the 1980s made about 150 horsepower NA... in the 2000's they make 300+ horsepower NA. The same applies to a 13b

Man, Civic with a K20A swap? Ask him to pop his hood, and look if it has a metal( alum) or a plastic(black) intake manifold... which is in the front on the K20.

If it has the balck one, he got the "Shitty" engine in it, which only has partial VTEC on the intake cam, but even that is better than the B16 or SOHC he had in it before! anyway, you "might" stand a 10% chance.

On the other hand, if it has the alum one, then it's the "good" one, and you're :sol:

What might save ya, is the fact it's a 2001 civic...which weighs quite a bit for it's size.
If this was a gutted 95 EG6, you would be so fucked it wouldn't even be funny! Those can keep up with a stock Trubo2 no problem!

FACT: People who dish out the $$$$$$ of dough for a K20 swap are not rice.

Yes, they were aware. Excuse my previous bravado. These were not huge wins at all. At most they were 5 car lengths from a dead stop which was a V6 Mustang. Other times I was hanging with them side by side (87 Supra Turbo). I'm not saying this car is magic or anything, but i'm not going to say it was slow either. It will definitely not beat something with a lot more horsepower, but it will beat something heavier with a moderate amount more horse power. This is not gospel, but I have done it quite a few times, regardless of what anyone might say. I'm not really posting this for my ego. I lost a lot as well, but i'd choose my battles.

Now, to beat something the same weight is a horse of a different color. That is why I suggested power adders. My hope was to steer him in the right direction. I'm not even that big a fan of drag racing.

+1 on this. The notion of it being a regular RSX motor and not the Type-S wasn't really addressed. Cross your fingers and hope for the regular motor.

Thats my old car with a stock port 13b with a little magic done here and there. And yes Ive personally beat easily a GSR swapped civic hatch and a 300zxtt among other car's. Please don't call me out or argue with me it's a fact and the car did it time and time again. But the amount of work involved to get there left the car unstreetable and very uncomfortable to drive which the ORP wants a daily and him beating this car wont happen.

For the NA: If you have the $$$ I would go Peripheral Port, Individual Throttle Bodies, and a microtech. You would hand his *** on a plate! But your drive train might not hold that power : ( lol.

I intended no offence, but that's a lot different than to simply say that your S4 beat all those cars. Still, on a stock port and stock manifolds the highest HP to the wheels that I've heard of is 174whp, and I think that was with an S5, expect slightly less with an S4.
