hi new to the site. i just got a rx7 not to long ago. right now its in the shop getting street ported/rebiuld. i have about another 2-2.5g's to blow away on this car. i thought about getting a power fc and tuning. what else should i get? i heard i should get injectors (1300cc) and a fuel rail (dont know what rx7 call it). would the pfc take care of the fuel issure with the fuel? after the pfc and the injectors i should have around another grand to spend on the car, what should i get? i am a lil new to rx7s
i already have a downpipe, mid pipe, intake,f-con, exhaust, all gauges i need, new fiulddyne radiator, new thermostats and cap.

 

i don't think you will have another grand to spend. The injectors and pfc are some expensive toys. Do you still have the stock turbos?? How much boost did you plan on running with your ported motor? 11's are definitly possible.....if your an amazing driver. The PFC is a must and a tune is a must and once you find out your wheel horse power it will be much easier to find out what you are going to be running in the 1/4 mile. You can also look in the time slip and dyno section and find someone with the same or similar mods as you have. Good luck with your goal!

 

yea i'm goin to be runnin on the stock turbos. they were rebiult 10,000 miles ago. i guess what are the lil things that can help me? i done all the maintances like sparkplugs/wire, oil change

 

well if you buy a power FC you can sell the FCON and get some money back. You will also need drag radials and a boost controller

 

About how many people on the forum have gotten into the 11's with the stock twins? Sequential or non?

 

full bolt on car with drag radials or slicks should hit 11s.

 

Yeah PFC will set you back $1200 fuel kit about $600-800, tuning is where the magic is at. That if everything is new which I would get on the fuel kit though

 

You didn't mention what intercooler you had. If its stock, you *could* try to be the first person ever to run 11s on the stock IC... Or you could not be insane and upgrade that too.

edit- btw, i put down ~300rwhp and ran 12.8@110 on street tires(S-03s). intake/ic/1200cc inj./supra fuel pump/power fc @1bar boost tuned by steve kan/ported engine/clutch & flywheel/dp/hiflo cat/rb exhaust.

 

so has any one ever hit 11's on stock twins no one has said any thing bout that yet and id also like to know if people have and if its seq. or non???

 

Yes, several people have been in the 11s on stock twins, it takes all the bolt-ons, ~14-15 psi, ecu, drag tires, and driving skill.

 

11's are not that uncommon on the stock twins. Atleast one or two people on here have dipped into the 10's on the stockers.

 

do you know off had if it was seq or non. its a big tose up IMO you could have SEQ to launch fast off the line but you also could have non. seq for when you already down that track ( if you know what i mean)

 

I was speaking on behalf of non-seq.

Don't need a fuel rail with the 1300's, they drop right in to the stock secondaries.

 

thanks alot for the info i start doing searchs on what else is needed and what not stuff
im hoping to hit low 12's by the end of the summer

right now i have apexi intake and silicon hose job and gutted cats and ACT CLUTCH ran it saterday night and got a 13.002
dunno if thats good but i read that bone stock FD's normally run mid to high 13's

 

You need to learn how the seq system functions, based on this post....

 

300 rwhp at 1 bar?

 

Driving skill, driving skill, driving skill. If you haven't ran the 1/4mile it'll take you many attempts even a full season to get your driving skills down. Tires are also very very important. Proper tune with a Upgraded IC is a must

 

i understand how the seq. system work but every thing that ive read on here says that when your non seq. your lag like a **** compared to seq

 

i've heard that lag is really noticible with non-seq, full boost ~3500 RPM. definately get a PFC and a tune, more power and safer than a piggyback. I've also heard horror stories about 1300cc injectors, because they are just bored out 850's (?) , and that they can fail (either open or closed). there were a bunch of threads back in late winter/early spring about them. personally, i'd drop a little extra cash and get a fuel rail and drop in some Bosch 1600's just to make sure that the injectors were designed to handle that amount of fuel, not modified to flow that much. like TurboJeff's avitar says, "do it once, do it right". also, upgrade your fuel pump with the fuel rail. you'll run a little over your budget for now, but you won't have to worry about needing more fuel down the road. either get a Walboro 255 LPH pump, a supra TT pump, and i think i've seen some people on here use a Skyline pump.

 

thanks alot whitey85mtu really apriciate all the advise i can
i want my FD done the right way the first time i dont want to have to keep going back and changing things

 

No, you don't, not based on your drag racing statement above.

Launching hard enough to hit 11s, you will be in full parallel mode almost immediately and will remain so for the rest of the run.....it won't matter if you're seq or non-seq in that case. Same goes for running the car on the track, you are essentially in non-seq the entire time....

 

ok then ...... i guess im retardedly confused...either way i just want to know one thing should i spend the time to go non seq. or should i keep it seq. and if i went seq. it would be the poor mans way just becuase i would like to do autocross with this car too.

 

Stay seq.

 

no problem. i've been a member of the forum for about a year and a half now, and i still can't afford a FD, but it's the best learning expierence i've ever been through. good luck.

 

that's why I'm going with 1200s...much more reliable according to Garfinkle, and he hasn't steered me wrong yet

I'm also going full non sequential because I want to get rid of as much crap under the hood as possible
