Yep. Many factors go into taking a car into the 9's, but the key here is that the T88 has the potential to bring the car into that range. But, this is assumed every other piece of the car is built correctly, for the turbo will not do it alone.

Meh, give him a break since he came clean guys.


I would say you don't need to run 9's to hit 220mph but you can't do it on our stock transmissions topping out at like 200mph with mucho power and perfect conditions.

Like I said in your other thread, if you're serious about going that fast then call up Racing Beat who is a VERY reputable RX-7 tuner and to my knowledge the only people who have taken a FD up to those speeds. After that, be prepared to shell out an astounding amount of money to actually do it and certainly don't expect to do it on public roads.

The T-78 is a BIG turbo, believe me i have one in my car, To give you an idea the turbine housing is about the size of a 32 oz powerade or gatoraid.

That battery isn't anywhere near the turbo, so your turbo size has essentially no direct effect on what size battery you can run. Look under your hood, dude! However, your choice of intercooler can require a smaller battery, a slight change in battery position, or a complete relocation of the battery to somewhere outside of the engine bay (bin or hatch area).

On a side note, i have seen 400rwhp on the stock twins @ 14psi on a pinneaple "raceport" motor. I believe it was near 15deg adv on the pfc from what I recall.

People running in the 9s and/or exceeding 200 mph aren't the type of people who have to create threads like this.

This is just another young kid who doesn't know any better. I don't know why you guys are encouraging him.

darkphantom: If you are serious, be prepared to be shelling out well over $20-25k and LEARNING HOW TO DRIVE before expecting to hit 9s in the quarter mile. Don't forget the frequent mechanical fixes and engine rebuilds. Do you know how few FD owners are in the 9s? And these are people with lots of money/sponsorship and YEARS of drag racing experience.

As far as 220 mph, give us a break.

as for the encouragement it doesnt really matter if people encourage me or not. All i am trying to do is get a point across. and for the fact you have always seen people putting and swapping 20b-3rotors. Now whats wrong with the engine in the car originally (13b-TT) thats what im trying to say. believing that you can as much with a 13b as you can do with a 20b. it just takes more work. besides im trying to encourage some people to do something that has never been done before. my opinion the 13b is a great engine and i wouldnt trade it for a 20b. thats the point.

Look at Red-Rx7's car. You can't do that with a 13B and have the same level of streetability or reliability.

I have a Stock Motor and I'm only running 14psi which is low boost for that turbo, theres no need for me to push my stock motor any harder so its running at only 14psi...

Now when the motor goes and i port it, i'll run atleast 16psi and have a lot higher hp numbers and plus 380rwhp is plenty of power, it would surprise you, i can't wait to see how hard it pulls when running higher boost.

I would think that you have run a 12.4 in the QM depending on the suspension you have.


My question is how does the car drive streetability wise??

A big single becomes less streetable than the car with twins. You're looking at not even feeling much power in 4th gear until around 4500rpm. If you're thinking this car is like a Supra with a big single then you're wrong. Most guys with big singles get somewhere between 400 and 500rwhp on pump gas and street ports. Not like the 700-800rwhp you see with Supras.

Breaking 9's in these cars isn't something slapping a big turbo on is going to do. I would say you're not going to be driving it on the street anymore when you build a car to go that fast. Not mention you need a full cage and NHRA license to even attempt it.

Ultimately, the 13B REW is simply not as good as the 20B when it comes to making power and being streetable. You can do a lot with a 13B, alot of people do. But ultimately in the quest for more power out of a rotary, you must swap in a 20B.

As for the 220mph run, to my knowledge only Racing Beat has done it and I'm sure that car was NOT streetable and had a huge amount of money invested into it and they STILL flipped it at 214mph before they got everything right.

I'm not trying to be an ******* here but I think you are in way over your head if you really think you can go out and run 9's in a street car then run it up to 220mph. That's impossible in anything but an all out race car.

darkphantom, what in the hell are you talking about? All I can say is keep dreaming. I'm starting to second guess whether you have any of the equipment at all.

what i have scene on dyno sheets is 1/3 more torque and half the spooling time
ex. 400ft/lbs coming in at 3500rpm vs 6k AND half the PSI (max HP still comes in at 7k-ish, still the same rotary design so it is expected) w/ the same turbo.

and less strain on the engine (when making the power w/ a 20b)

another thought.. with a 13b built ,ported and pinned you can still have that power made out of a health stock ported 20b

and for your information, a six speed rx8 transmission did fit. and i got pictures to prove it. RYNBRG is the dumbest one of all cause he dont know ****, cant do ****, and is ****. anything is possible, it just takes time. I saw a 13b in a rx7 doing 9.62's so thats proof that it can be done here is a 9 seond RX-7

http://www.rx-7.com/events/040800.html

so this kid should not be cut any freeking slack and you guys should not be giving him the pleasure of answering his fantasy car questions until he can learn to respect ppl. this kid obviously has some social prolems that need to be addressed. but for now stop encouraging him to post. i think its safe to say this kid is a liar. i doubt he has many friends and he needs to find converation online but no1 should be feeding his need to lie all the time by answering his bs fantasy questions.
