I want to run stock twins around 14-15psi, on the list of things to get.....

Greddy Airinx Intake
RX7store DP/MP combo
RB Dual Exhaust
Power FC+Commander
Fluidyne Radiator
Nippondenso Fuel Pump
XS Engineering Ignition
Greddy 2-Row FMIC for stock twins

Suggestions would be nice(parts wise) if something sounds wrong please let me know. Just an estimate of what i would be running whp wise with proper tuning.
Thanks

 

i would say at 15psi maybe 300-330 rwhp. i'm running a similar setup, but have never dynoed. maybe upgrade your secondaries too. and get a 3bar map sensor. just a thought.
good luck.

 

Take a look in the dyno threads and see what people are putting down with similar mods:

Thanks for the info. My goal rwhp is anywhere between 350 and 375. I'll check to see what else i could get to make that goal.

 

You will need larger injectors to run that psi, i have very similar mods and i just put down 303rwhp at 12.5psi

 

What is the most psi and power you can get out of the stock motor and twins. I think i heard 450hp for the motor, not sure on the turbos though

 

Whatever selected turbo(s) is going to be your limiting factor before the engine.

 

I came to a conclusion that this is what's making my car squal when it warms up. I get the car up to operating temp. and when i go from 2200rpms up to 2400rpms it squeals. I notice that when i push on the gas this piece spins then stops, is there anything i can spray on this to keep it from squealing? Once i redline the car it stops completely, not sure whats going on with it.

 

sorry the pic is small, it would only let me get a pic that was 100kb

 

If it's the belt, just replace the belt. If it's the airpump itself, it may be getting ready to fail.

If it's the ACV return line, just make sure it's going all the way into the stock airbox.

 

On a stock port motor I would say 14 PSI is going to give you anywhere from 310 to 320

Now if it was ported you might could pull 340 at 14 PSI.

 

I'll post a bigger picture later, but it's the thing that spins in the pulley.

 

That's gonna be really hard to get on stock twins. No problem for upgraded twins or single turbo, but i think 350 rwhp is pretty much the outer hp range for the stock twins. but i'm no expert.

 

Bigger injectors and 14psi you should be creeping up on 350rwhp (dynojet).

You could probably squeeze by on stock injectors, but that leaves very little room for error or a bad tank of gas.

 

Thanks alot for the info, I was thinking about porting my motor the only thing is that the motor i have now runs great nothing wrong at all, 80,000 miles to the date. I was thinking of going 850cc primary and maybe somewhere around 1300cc secondary.

 

ha more power than me ill tell you that

 

I plan on putting down close to 400 (dynojet) on my stock twins.

 

What do you plan on having for your setup villision? I'll be back at my house tom. night so pic will be up sunday night or monday sometime. I'm thinking its the air pump. Since i plan on getting a dp and mp, i just as well remove the air pump anyways.

 

mods are

pfc
complete fuel system 1600cc injec
greddy fmic
race ported motor
ported turbos and all manifolds
ground wiring kit
hard intake pipes,k&n filters
hks twinpower
3" back to a 4"catback
under drive pullys

A lot of tuning and working out bugs i plan on putting down 375-400 hp dynojet numbers.
