MY CAR 08 5SPD

MY PLANS trd supercharger, i already have greddy catback and a header...

that being said the supercharger im getting has no ecu flash or injectors, if i plan on running 9.5psi pully what size injectors and whats the most cost effective piggyback to get.. i want a dependable daily driver and the emphasis is not on max power output but rather affordability..

thanks in adavance!!!

 

I'd recommend 700cc injectors and a walbro 255 pump.

You will also need some form of engine management as well.

...waiting for unknowledgable N/A tC owner to post comment bashing S/C and tell OP to go turbo instead. . . . . .

 

why 700 cc? the stock supercharger injectors are smaller than 440 right? he just wants daily driver with some fun.

sounds like you'll just need a piggyback ecu for tuning and some decent injectors. a fuel pump and giant injectors seem unnecessary with only 9.5 psi.

 

not a N/A owner
Dude, good choice!
I love my S/C and I'm only just beginning to play with it

 

haha well, i mean when i was i/h/e/spipe I really considered the supercharger. But after reading howmany issues people had with them i really didnt wanna put up with that. cost vs power imo wasnt worth it. Now im turbo and its fantastic!!! You could buy a turbo kit and just run lower boost on it and it could be very reliable.

ps: paul see you sat. for my tune ;)

 

i have a friend with a aem fic for sale... beats paying full price.....let me know..

 

700 cc ? why? even with the 14.5 pulley he still will never need something like that
yeah 05-06 are the 410 cc and the the 07-09 are the 440's, if they are stable enough to run on 90% the 9.5 pulleys sets ups with the reflash... the trd inkectors and a fic will do just fine

thats what i was gonna do but i ended up boosting so i sold everything

 

+1

 

+1

 

im looking at the blue emanage and maybe some 440 cc injectors the kit i bought has a K&n cold air intake also!!

 

Paul, is there any reason why you picked the 700cc injector when considering that the SC( or any type of centrifugal SC) is not that efficient?

 

true when you lower your psi it can be good to drive normal on. I was looking into Turbo too and think its the best route. Am not bashing on the S/C due to the fact i was really considering going that route just for the easy, clean and cool due to the fact its TRD and made just for your car from them. but now they dont even wanna claim responsibility because they started breaking and sh!!!t and doesn't give a warranty now. If you go with a good turbo and not some ebay POS they take care of you, I was looking into Ptuning they sound legit and help out ALOT. another thing is to find a S/C with all the parts you need and not cracked or F'd up is kinda lucky and to buy it brand new even with the new discount its still fkn alot of money and to just spend the extra 700 or 800 to go turbo with alot more fun and the extra B-YaaAaAAaAA when need to smash a s/c, and with a good dyno and high psi your car is faster the a Subaru. on their threads they were asking eachother how our T/C scions can keep up with their cars.

 

Superchargers suck!.........go turbo.......lol j/k......the only advice I have for going turbo or SC is: don't boost on a budget, is good to have some money saved up just in case........

 

Thanks for the input everyone.

 

Yes, and I am glad you asked about this.

The 550cc injectors were not enough fuel delivery when running 9+ PSI on the TRD S/C. The reason being is that you do not have many ways on this setup of keeping charge temps down, which only leaves you with a hand-full of options...

1) Add some form of intercooling

2) Run a higher quality fuel with more detonation threshold

3) Run conservative timing with a richer AFR on a pump fuel (ie. 93)

I noticed that the duty cycles from AFRs we had to run on a 550 injector where rather high, which if you are planning to expand any more with a larger pulley or do not want to run a REALLY high duty cycle, then a 700 is an awesome choice.

 

IDK paul, it usually isn't a habit of mine to second guess you, but when i had the TRD supercharger, using the supplied 410 or whatever they were injectors with the 9.5 psi nst pulley, and the TRD reflash, my intake temps would usually only be 10 above ambient air temp. i think the one really hot day i took it to the track it when it was 110 degrees, i don't remember seeing anything higher than 15-20 degrees above ambient air intake temp, and i did 9 runs back to back.

 

550cc should be plenty for the 9.5 along with the stock fuel pump.

 

So could i run a TRD S/C at 8.5-9.5 psi leaving everything else stock?
just dont have the funds to completely re-build my engine yet

 

Yes you can. 99% of the people with that same set up are on tge reflash.

Really no need to do any fueling upgrades for 200-220 whp.

My boy just bought a fic for his set up. But he also has all 4 nst pulleys, 007 bpv, wr s/c intake. And he wants to tune it so it doesn't run lean.
