Where do you live?
Im in Ottawa, Nepean.
How much to port, and have you done it before?
I could drive my car to you but I dont have engine lift and **** to take it out and take it apart, I dont have the time iether. How long would it take you?

R.P.M.

iTrader: (3)

I'm near Walkerton....last time I drove to Ottawa, it took me almost 8 hours!!
I'm not allowed to post prices for porting or engine rebuilding because the mods get pissed for some reason, so I'll pm you some prices. I have helped out a few member here on the forum with porting and engine rebuilding....so ask around.

How long?? Well with a full time job during the week, I only get to play with the engines whenever there is spare time.....so my turnaround time is sometimes lengthy......

s4Lt

Aight well. Ill look around, cuz I cant not have my car for more then 3 days.
And if it cost more the 200$ then I wont even bother porting because Ill put that money towards the turbo engin that I want to get.

R.P.M.

Now your thinkin Keep the money for a T2!!

rx_prez

It will definatwly cost mosre than 200. well it sure as hell did for me anyways.

nik

The soft seals alone for an engine rebuild cost more than 200$. You have no choice but to buy these seals new as some of them come apart when you dissasemble.

Also, if you can't afford even 3 days downtime on your car, then I would suggest buying a second motor and just rebuilding that if you still want it ported. Then once its ready to go you can just take a couple days and install it.

RXcetera

You seem like a nice guy, so it's hard to flame you, but you really should try reading up more on rotaries and cars in general. Porting your motor (which means rebuilding it) will cost you over 2000$ and will take at least a couple weeks. This isnt Grand Tourismo... you'll find that in the real world, you have to consider $$, down time and reliability!

It sounds like all you want to do is beat your friends Nissan at the drags. If that's what you bought your car for, you bought the wrong car. Sell it and buy something that's actually fast in the 1/4 mile! You cant just getto your way to speed in an RX-7... somewhere you have to spend the big $ or you'll just end up with a busted car. And even if you do avoid the eventual blowup for awhile, your car will still be slow compared to most of the cars at the drags.

As others have mentioned already, your only real and cheap option here is to lighten your car as much as possible. Take out all the carpets, soundproofing, doorpanels, whatever. Your car will suck in every aspect except gaining maybe .5secs in the 1/4 but at least you might be able to beat your buddy.

RXcetera

Oh and for comparisons sake, RXciting ran an average ~15.9 at Luskville last year with a completely gutted car (no interior) and full exhaust among other things. NSF05 ran a ~16.1 with a mildly stripped interior and full RB exhaust with modified intake.

Correct me if I'm wrong on those times guys...

s4Lt

Well for 2050$ +tax I am going to be able to get a TII for my car, working and ready to drag. So ill do that next year. I have everyhting in my car inclueding heavy sound system and spun my tires and I still got 16.269 on 1/4 mile. I like rotary to much and wont go to piston ever. I know that RX-7's are faster then a 240sx. I could have probably gotten 16 flat had I not spun tires, maybe even high 15's. I dont want it only for 1/4 mile but for solos and curves and ****. So after I get the TII I wont need very much to beat him, I wont need anything else but that. Even if he get his turbo engine he wont be able to beat a TII Rotary. So in the end I will beat him and next year ill kill him with the TII. So yah. I read in another thread that to make a short throw shifter you can cut off a peace of the stock shifter and weld it back together, do I have to make the bottum part of the shifter shorter or longer to make shorter throws. Cuz I dont want to spend the almost 200$ US to get a shifter. What else am I going to have to get to make it all work? Spacers or what?

RXciting

15.7 actually, with my POS rear suspension that squats like crazy and barely making it into 3rd haha!

But yea, my only bragging rights would be 15.7

Edit, i think NSF05 actually managed a 15.9 later on in the summer or on a later run.

RXciting

As i showed RXcetera last year getting someone else to do the welding for you is a bad idea for a short throw shifter, unless that person actually knows what they're doing.

BTW i need Bar B Barns!!!

s4Lt

Ill be doing the welding myself, but I need to know wether I have to shorted the bottum part of the shifter or make it longer? Ill be trying to hit the 15's Saturday. Hopefully I can do it.

There are a few things you'll have to do:

The part under the ball has to get longer.
But in doing so, the bottom of the shifter can't sit lower than it does now - so the big "Ball" will now sit higher than it did before. Because of this, you will need to fab up 2 pieces:
1) A spacer that will lift up and support the bearing under the ball.
2) A new ring with a peg that will locate the large ball and stop it from turning.

You will also need 3 new bolts that will hold everything together.
Go to Mazdatrix.com and look at the pic of their kit, and read installation writeup. Then you will have a beeter idea of what you will need to fab up.

There is a reason that these are expensive!

s4Lt

Does anyone in ottawa have an extra one that I can purchase off them with everything ill need to do the install?

s4Lt

Does the shortthrow shifter even do anything good when it comes to 1/4 mile?
Is it worth the money?

nik

My guess is that a short throw shifter will actually make you slower since you'll have to get used to it and may miss gears. But I don't have one so I can't say for sure.

If you're dead set on one, do some searching as I think someone has figured out you can retrofit a miata short shifter for use in the FC. There was a thread on it in second gen section. Its a lot cheaper than the mazdatrix one.

RXcetera

The stock throws are already short enough... wait til you have a better clutch. Try focusing on your driving instead. That doesnt cost anything.

WankelingBeer

You guys and your damn rotaxes are all slow.

i ran the 15.9 2 years before we raced...
and i was a cold night(15C)

How do RX-7's handle 100+ Octane? I'm thinking of using it before the day of racing on Saturday.

FC3S.USD

iTrader: (2)

That works if you have a turbo, bring up the boost a bit. But Im guessing you have a NA asyou said you wanted to do a turbo II conversion.

So you don t need to spend $ 2.50 a litre for 101 octane or $ 5.00 for C16.

RXciting

Higher octane in an N/A will probably, if anything, make it lose power.
use the lowest octane you can get your hands on, if you can weld just make a straight pipe to replace the 3 cats in your exhaust and try and fab up a nice cold air intake.

Take out your stereo system, and so some reading on what other ppl have done to make better use of the stock engines power.

Good luck on the 1/4

s4Lt

I already took out emision and went straight and I did fab up a cold air intake.
But thanks.
My RX7 doesn't like anything other then 91-94 octane gas.
I drives like **** if I put 87.
