got ya man an yes i hav rode in a 10sec car i grew up around the tracks the only reason i asked was too get som input but DEZERTE if u dont lik the post dont read it

 

Something like this....




That is an older pic... the manifold is fully divided and equal length. It runs twin wastegates. On the old setup (HKS manifold and same turbo) it made 447 rwhp at 14 psi. Now it will run 22-23 psi and a 75 shot of nitrous. I can post new pics later tonight...

 

man now thats a good one, an dont get me wrong i searched for awhile but theres somting wrong it keeps saying The Page Cannot Be Displayed when i hit search, not srue what the prob is so i just figured id ask thats kinda the point of a Forum isnt it?

 

no bother postin nemore im not goin to read since nobody will take me seriously

 

One side note, even though I'm sure you won't read this: If your posts are done in standard written English, with punctuation, people will take you a LOT more seriously. On the Internet, nobody can tell if you're 16 or 46, except for your text. I'm willing to bet someone could ask the exact same question, except typed properly, and get a much more respectable set of responses.

You come off as immature in your poorly typed posts. People aren't likely to take you seriously. It's just the nature of the Internet.

i dont think he knows how fast 10 seconds is. the forum members are right, you will need to build a 13 second car first, which can be streetable. to make enough power to get to ten seconds, you will need to become a gearhead, through and through. you car will not be driveable on the street. you will need to drop at least 5-10 grand on the car.
the car will need extreme weight reduction, as well as stronger driveline and probably a complete motor swap of some sort.
going v8 would be the easiest and cheapest way to muscle through to 12 seconds.
if you want to stay rotary, a 3 rotor (american rx-7's have 2 rotors) 20b will be very expensive and will have to be imported from japan. youre looking at about 7 grand for the complete swap, assuming shop labor.
you can pick up a 13bt from a turbo rx-7 for less than 5 grand, but if you have to remember that 86-88 is series4 and 89-91 is series 5. swapping between series can add costs and difficulty between swaps, however series 5 motors are rated at higher powers, but less reliable, as they use late 80's electronic monitoring technology was fairly unreliable.

to conclude, you could make a very nice 13 second car using a modified 13bt and some moderate modifications. it will be barely streetable (smogwise) but 13 seconds is pretty fast.

id reccomend searching through and reading these forums, you will learn alot of interesting things about rotary's if you take some time to read

 

Shh, if you grew up around the tracks, then you wouldnt come here to ask how to make a 10 second car..

 

A 16 y/o in a 10 second car, brilliant! I'm 20 and I can easily slide out my STOCK '91 NA when it's just a little wet out.

 

I wish you luck, but remember that speed costs money, How fast do you want to go. From what I have thought , put a small block Chevy witlh a Wiand 6-71 blower or somthing lie that in there. I also assume that this will primarily be a straight line car, so superior handling is not an issue. Personally I think it's wrong to put in an Otto cycle engine in one of these cars. It just takes away from the mystique of having a RX-7. IMO The Wankel rotary makes it the car it is.

 

Good luck getting to 10 seconds. My friend has an FD that runs 10.1@135mph (at 4700ft) and that thing sure as **** wasn't cheap to build. He put about 60 hours of porting and has a T884 (or is it 844 I don't remember but the thing is big enough to be used as a swamp cooler.) His car puts down roughly 730rwhp and he runs tens. Here's what I would do. Keep the motor and sell your car as a shell. Drop the motor into a gutted GSL-SE and do a peripheral port with dual carbs and a 75hp shot of nitrous.

 

Sorry buddy but you don't need a 10 second ricer, all you will do is end up killing yourself.

Go read the timeslips and dyno section.

GET AN EDUCATION, GET A JOB and then ask.

BTW: English is the first tool you need

 

jk88 dude im 16 also own an 87 TII with an S5 Jspec in it i have aol instant messenger sn is CA TwEaK123 if you have any info IM me ive posted questions like this back when i had my GXL and i got the same replys noone here really gets taken seriously unless you say you got 50k to spend...

not even worth the bandwith to tell the kid off.

 

lets close this now.. aarons warning about smart *** replies seems to have gone unheaded.
