ok go a 93 fd with a stand alone ecu, greddy 75mm turbo kit , 3 inch exhaust system, greddy turbo timer , and a apexi boost contoroler, and few other things , but anyway puttin out about 350 rwhp at 10psi and was looking to put her at about 450 to 500 for this year , so just wanted to know some things i will need and should look in to and wanted some good advice ??

20 psi, Water/meth kit and you should be there as long as your fuel pump and injectors are appropriately sized. Also it usually takes longer than one minute for people to answer so be patient

Complete fuel system-injectors, rails, fuel pump

cooling system-new radiator, intercooler, A/I injection or a E85 tune

Motor with good compression

Great rotary tuner to not blow the motor.

Just to list a few things.

harnum2009

ok so wa size of fuel injectors , and fuel pump would i be needing and best brands?

TwinCharged RX7

iTrader: (14)

2 walbro fuel pumps (both in tank, rewired)
1600cc primaries (bosch are common)
720cc or 850cc primaries
- you'll need new fuel rails for both, unless you modify your stock primary rail and put the stock secondary 850cc's in it as primaries (save a bit of money)
fuel pressure regulator (SARD and Aeromotive are common)

You have a stand alone ecu so i'm guessing you don't need resistors on the fuel injector wiring.

Any progressively controlled (increased pressure as boost increases) meth/water injection kit. for 500whp i would go with 2 625ml/min nozzles. Most kits come with the same pump, made by sureflow. there are two sizes, 150lbs and a 225, the small one is plenty (and can be turned up to 190 i believe). Go with braided A/N lines for all of this, i used the quick connect plastic lines with osmosis fitting that are used, but they have leaked and been replaced on more than one occasion, im switching to braided this winter.

All that and a good tune and I think you should be good, possibly better spark plug wires. you should at least go to 9's for plugs all the way around, but around 500hp i'd recommend going to 10.5's all around (i had misfire issues until i did that)

and make sure you have proper cooling and a fresh fuel filter before you get tuned.

Good luck

few things that haven't been listed yet.
with the aux injection, go pre turbo, make sure you have the injector bang smack in the center.
with the right tuner, you can get more than your goal, but it HAS to be somebody with the experience if you want it to last.
i would also go with at least a 4" exhaust with no cat and preferably straight-through muffler(s).
if you have to get a new intercooler and radiator anyways, then you might as well go v-mount as well, you'll have cooler water temps, and better boost response, especially with proper ducting.
now you don't NEED all of that to get that much power, but it would be a good idea since it will be a street car, and i'm sure you'd like it to last as long as possible.

anyways, good lckk!

if he goes meth he wouldnt go pre turbo would he? isnt that just for water?

harnum2009

what is this meth kit all about i been looking for things on it but just cant figure it out , whats it goin to do for me ?

duval7

IMO the meth or AI injection is one of the most important upgrades an FD owner can make. It injects water, mixture of water/meth, or pure meth into the intake lowering the intake charge and therefore lowering the combustion temp while removing carbon from the engine. You can run it for just reliablity or you can tune to it as it allows you to run more boost and timing. Read the Auxiliary injection thread, it goes into detail about this.

harnum2009

so is it like a kit that u have to re fill or something or when u buys the kit u just install it and thats it ?

FDcurt

iTrader: (4)

U have to refill whenever it runs out. Depending on how much you use the kit and where you set it depends on how often you have to fill it. Look at yaw power injectors. I have 1000/2225 and i got better gas millage than when i has stock 550 and bosch 1680.

With regards to the auxilary/meth/water injection.

The kit will come with a resevoir (some people use their windshield washer tank), i run 100% meth, so i purchased a 1 gallon fuel cell off ebay (typically used for go carts). You can get a level sensor and run an LED in the cabin to tell you when it gets low. I go through less than a gallon a month.

Mine is set to turn on at 13psi, and then increases pressure as the boost rises (i havent gone past 20psi boost yet)

You can get a 5 gallon barrel of methanol at a race shop, or you can use water injection, or a mix of both. I'd recommend methanol if you are going for more than 400whp (although there are many that have done it without, but i'd rather be safe than sorry). I also don't recommend running a mix, you will get tuned on a specific mixture, if you mess up the portions in your next mix and are pushing the car hard in high boost, the tune will no longer be specific to your fuel mix and then you have an added risk to your engine.

In CT i can get methanol for about $8.00 a gallon.

Its pretty much like adding tiny second super high octane gas tank/injection system that is only utilized when under high boost.

I got almost the same setup with a T-78, and I am going meth for all the reason previousely stated. What injectors are you running on your setup now though?

harnum2009

ok i under stand now.... but ya im am using the stock injectors rite now thougth

harnum2009

is this kit any good or something on that page? http://cgi.ebay.ca/AEM-WATER-METH-ME...item3ca72b79b6

TwinCharged RX7

AEM makes a good controller, everything else is pretty much standard in all kits.

But I wouldnt get that kit, as you will have to spend more money. The tubing it comes with (high burst plastic tubing) and the osmosis type connectors aren't the best, especially in a high heat environment such as a rotary engine bay. I have found mine leaking 3 or 4 times (extremely bad in many ways, risk of fire, or not injecting enough and blowing the engine). Definitely go with braided lines with A/N fittings. Then you never have to worry about leaks.

Also, if using 100% meth, i don't like using the plastic windshield washer type tanks they provide, i like a small fuel cell, 80 bucks on ebay. If you are in an accident they will crack open and you will have meth everywhere. (I think thats why the link says compatible with meth up to 50% diluted in water)

Also, every kit uses that pump (made by shurflo), and its a great pump. But Alkycontrol modifies the pump to make it even more reliable (google alkycontrol to find their website).

I have 2 625mil/min nozzles.

It's pretty easy just to piece everything together. I know Alkycontrol is one of the best, comes with a modified pump, and braided stainless lines cut to length. not sure about the pricing compared to others though.

I'm currently using snow performance, and have been happy with them as well. But again the only big difference between the major brands is the controller itself.

harnum2009

so with this kit it will allow me to run on pumped gas (91 oct)

We are bringing an entry level mehanical kit in very soon that should be around 400 USD mark that will be good for around 700rwhp.

For more details You can pm me.

for what u said there i cant understand this part
1600cc primaries (bosch are common)

looking for my injectors now and unsure what to get??

FDcurt

http://www.injectordynamics.com/

has a fuel/hp calculator. Should help

harnum2009

ok there are primary fuel injectors and secondary injectors , so what size do i need for primaries and what size for secondaries ? and what about a fuel rail? and also what size are the walbro fuel pump ,, (255 LPH) ???? also what about the fuel lines are stock ones good or will i have to up size , what size would i need and kind to get???

WaachBack

iTrader: (21)

850cc Primarys
1680cc Secondary
2 255LPH HIGH PRESSURE Walbro Pumps

Stock lines are fine for your goals.

Chaotic_FC

go with yawpower 1000cc primaries and secondaries.
they are high impendance, which means that it will act like a smaller injector, at low delivery.

harnum2009

so when im buying injectors are they 1000 cc each or are the 500cc each
and when buying 1600cc are these for both?
