Is it Possible to for a 13b without turbo, supercharger or bridgeport to do 160mph??
 

My dream is to reach the end of my speedometer, and that's 160mph, just thought I would throw this question out there.

Yes.

RTR, haha, you gotta give me some hints bro! are we talking a fat porting job, and straight pipe exhaust along with performance intake, maybe a light weight flywheel?? or is there something else??

Naws

:((

don't worry about me killin myself, but i understand your responsible approach. 40 more miles per hour wont be anything too hard, i've youtube vids of 120, driving straight is driving straight my friend haha

anyone knows how much more power a bridge port adds to an 88 NA? assuming racing beat full exhaust and cold air intake?

He was driving strait, didn't workout so well for him now did it.

i'll take my chances, but i think there is a diff between 160 and 210 haha

yah its possible but the first thing you need is a long ass straight away like the salt flats and not on a public road cuz that shits just stupid

Yeah man, a bridge will do with a nice shot of nos probably. Maybe even a good PP might do the trick.

And yeah, there are some MAJOR differences aerodynamically betweent 160 mph and 210 mph. The increase is exponential.

lots and lots of downforce.

Turn the 6pi into a large 4 port. Or go P-Port. I would want an aftermarket engine management system and a dyno though. You would most definitely need over 200hp and of course you would want the car lowered... I have only done around 125mph... And that was on a tired stock engine and stock suspension. 160mph is a tall order for an N/A car but it could be done. It just takes time, $$$, horsepower, a relatively safe place to do it, and some common aerodynamics (something that is almost already taken care of for you with the FC). If you plan on doing it on the streets, please make sure you are ready for the possible outcomes... Better yet, just don't even do it on the streets.

(P.S. front and rear splitters/diffusers/whatever you want to call 'em might help...)

I went 149mph in my n/a took to long.

Just throw a turbo on there, it'll help. (Get there quicker)

160 mph aint no walk in the park. My old 88 turbo II with 3" turbo back exhaust (and pretty much otherwise stock) did 148mph before it was maxed out. Anyways, don't do it, there is not much excitement to be gained when considering the risks your taking, may as well go autocrossing and have a lot more fun and what do you know, you'll be a lot safer doing so (hopefully:)
.

my 87 tii pegged the speedometer (160mph) and then some with nothing more than an intake and gutted cat. massive boost creep and very cold ambient temps. Even though I did it in a dry lake bed, in hindsight, I was young and stupid (8 years ago?).

1) Probably not as much of a thrill as you think it will be. It'll take a long time to get to speed and there's nothing to feel when accelerating so slowly.
2) Need a massive space to do it safely
3) Even if using a massive area, you probably wont have the proper safety personnel present (EMTs, fire, etc)
4) Its an rx7, take it for some twisty's. You'll be much more satisfied.


40mph diff? 50mph diff?

Actually, I'd say that went relatively well.

To the OP what speed are your tires rated to? That should be your first question, at least to yourself. Don't kill yourself! :)

ls1? jk jk jk

honestly, safety first. but i dont think you can do it on a 13b, even with 13b-re block with rx-8 rotors. maybe if you had naws, but you would need either a huge 125 shot, or like 4 20 pound bottles to hold a 50shot for a long time, don't forget the bottle warmers.

this is off topic but can you fit a 93+ rx7 engine into a 2nd gen?? rx7store.net has a 93+ with a fat turbo on it, race ported, for like 3 grand, maybe 4 after every little thing but that would the job!!

The FAQ thread has all the answers you need :)

The stock speedometer is horribly inaccurate over speeds of 75. Just sayin.





And to the OP:
Just put the 7 on a cargo plane.
Done.

There's no f*cking way a stock block NA FC will hit 160 MPH actual speed. You might get it indicated if you put 13" tires on it or change differential/speedo gear until it's 30% off.

There's simply too much air resistance and not enough power. If you had maybe 300 HP it would be possible.

@MaczPayne, i went to FAQ and searched "swap" and got nothing, i know people will get mad if i post a thread titled "is it possible to put a 93+ 2 rotor in a 2nd gen" so yea haha

5th post about half way down.


And for the original question, as others have said, I think it will take a lot of time and money and will definitely not be as cool as you think it will be. There are much better ways to invest your time and money into your car.
