hello guys sorry if this is a stupid question but im new to the rx7 i just purchased a93 fd with a pfc already in it im planning to swap out the tt for a greddy t88 kit and rx7 store ultimate fuel system will i pass emissions with this kind of a set-up and if i could get anything on how to program my pfc for this type of setup would be very helpful also whats the safest setup for the stock internals would i be ok with the setip i mentioned? plz help!!!!!

 

You got a large turbo and large fuel delivery system... You're planning on not modifying/rebuilding the internals at all on an engine with who knows how many miles on it... and you live in el paso where it's like 100 degress or more 5 months out of the year. Is this going to be a daily commuter car too?

On a more serious note, with what you've mentioned, I'd guess there's going to be a slim chance of passing emissions, but that depends on the state of the cat and the o2 sensor etc etc and you'd have to have a super lean fuel map.

 

the cart has 57,000 miles on it and im planning on working on the internals but new to the rotary set-up? im looking for safe and dependable kit that would get me around 480 hp and pass emissions any ideas?

 

nevermind dunb question i was thinking of the obd II

 

There is not dependable 480whp turbo rotary setup, well unless your idea of dependable is 5-20k miles between rebuilds. It is a give an take just like any other car, the more power, the less reliability and comfort. The rotary is even more finicky than any other car on the road.

 

i dont want rebuilds that often lol what do you suggest to sturdy up the internals a which kit would be best for a daily drivin car with plenty of ***** ?

 

Honestly, you gotta remember the FD is pretty light and can have alot of forward thrust out on the road without the numbers looking that big. If you did some lightening of the car you can easily take out 100-200 pounds. Iron side housings, stock exhaust, stock turbo system, body parts. There are lightweight alternatives for all of these pieces. The car is already fairly light (2840 pounds approx. curb weight). This is less than what a current Civic Si weighs. A current Z06 vette has 500 hp at the crank , which translates to approx 460-470 at the wheels. But the car weighs 3132 pounds approx. This gives a hp/lb ratio of 6.74 pounds for every hp. To get that in a lightened RX7 (say 100 lbs below the curb weight number I gave) 406 hp would be required approx.

But getting 406 hp would have to be on a "track/race" boost map. You'd want to have something more conservative for daily driving (say 4 psi lower boost) if you're going to make the eninge last. Honestly though, with 57k on the internals, you should probably just rebuild it because it won't last through this summer if you put that big turbo on it.

 

well if can resort to a smaller more reliable turbo and still reach those numbers which would be my best bet? and as for passing emissions sinse the car is a 93 theres no obd II test am i correct?

 

That's up for debate for sure, there are a million different opinions and I am not a turbo expert.

Though I do dig the Turbonetics GT-K series turbos.

 

i was thinking maybe along the lines of a gt35r but unsure what it really can do i want numbers somewhere in the 4 thats what im shooting for

 

dependable and emissions legal will put you at about 300 hp in the state of texas. a rotary usually won't pass emissions in texas without a cat, so that would limit it a lot as far as boost. 300 hp will also only be dependable if the set up is tuned right. a bad afr at 300 will get torn up.

our cars are not exactly notorious for reliability when the modding starts.

 

ya im planning on having my pfc tuned by a pro not me... but i was wanting to get somewhere on the 400 range what about the to4z would that be ok with the stock internals and if not what kind of internal? any ideas?

 

 

This thread is hilarious .

Why 480? why not 475? emissions legal aint gonna happen on a 2 rotor much over 300 to the wheels.

Take your FD to either rotary performance or gotham racing (both in the dfw area) and write them a blank check.

 

t88 on a stock port motor? hahaha! do some more research this "400" question has been asked a billion times.

 

the t88 is old news i was asking about the t04z as i am new to the rotary cars and gave them benefit of the doubt that it could handle more then a piston engine im starting to think this fd might have been a bad idea with the way you huys are talking seems like its all bad but none the less i was asking for help on what kind of internal mods should i need to get me into this range i was not asking for you to make fun of this thread.......

 

They will be able to tell you what you need to here and then you can decide what to do!

 

If a man on the street came up to you and wanted to have a serious discussion with you about the earth being flat, would you laugh or talk with him? The answers to your questions are in these forums, you just aren't spending the time to look for them.

And you seem to be forgetting that this is a 1.3L motor. Yea it's a rotary, but still... 1.3L! Do you know how much the honda guys with a B16 would have to do to get 400 hp at the wheels in a package that's even remotely streetable? Can you say down payment on a house?

Check out pineapple racing's site, they have some interesting stuff and prices for rebuilds and ports. Plus they have some vids going over rotary engine stuff. You could probably find out a little bit more about what you're into with the FD.

thank you... ive been going thru the forums and found a bunch of answers to other questions asked and this site is great to learn new things on the rotary and the way it works thanks for the link and sugestions right now im ditching the t88 and looking more towards a smaller more dependable setup im still looking for good numbers that are doable...

 

i, personally prefer garrett turbos if you want to look into that. the gt35 series is a good, daily style turbo, or you could go bigger with something like a gt40 or gt42. all very streetable and reliable. they are also water and oil cooled like the stock turbo and are dual ball bearing instead of journal style like some other turbos.

 

which would give my nice and quick spool up thats what i have been looking at and since it doesnt require major internal mods to be done it looks like thats the way im going to go thank you....

 

Not breaking your *****, but if you would have spent some time in the single turbo archives you would have come to this same conclusion

 

Haha Ya

 

haha i realized that that but ive been going thru them alot and found alot of valuebale info in here but still thank you guys for the help....
