Default I/E mods (quick question)

did some searchin and didnt find the answer i was lookin for...

well i was strongly considering dropping a TRD supercharger into my tc but that was kinda put to rest once gas hit $4 a gallon. However i still want some performance in my little ride. i was thinkin of droppin a greddy sp2 catback and prob either TRD cai or injen.

if i take and drop those N/A mods in and i stay away from F/I, can i continue running 87 or if i up the airflow like that id need to run 93? i dont mind sacrificing a few MPG as long as i can stick with 87.

staying away from replacing the header for right now.

87, 93 would be a total waste.

Anyone who says otherwise doesn't know what they're talking about.

intakes do nothing for performance on this car.. they are for looks and sound.

Catback will get minimal gains as well.

to say they do "nothing" is not completely accurate. However, for this car any bolt on will give very minimal gains compared to a high compression motor. You will maybe see 3-6 hp off the intake and 5-10 TS on a full exhaust excluding the header.

Maybe it should read - "nothing that you can feel"...

that is correct. The only way you would be able to tell the difference is if you got two identical tC's, cloned the driver so both cars are exactly the same with the exact same driver skill, and you might see the tC with the intake get ahead of the stock one very slowly after about 70+ mph

Saying intakes do nothing but sound are a far stretch. Obviously they don't add hp like any turbo or supercharger but they still help. Somewhere I saw a dyno on a stock car with just the Injen CAI and it added 5+ hp. Obviously its nothing crazy but it does help.

Anyways to the OP, you won't be gaining that much more airflow. The reason why s/c or turbos require premium is because a LOT of air is pushed through the motor at a compressed state, the higher octane resits predetonation in the motor to help make the power seen by f/i.

so it seems like i should save the money and just drop the s/c in.

for now i think im just gonna drop it with some TRD springs and a strut bar so help it corner a bit better without the rolling feeling at more G's

No that's not what it means.

Do this since you're wanting to save a bit of money on gas.

First get an intake.. CAI preferably.

Then get a cat-back exhaust.

Then get a header (but research for one that won't have fitment issues with a S/C)

Then eventually get the S/C. All of these other mods SUPPORT the S/C. If you were going turbo then that's a different story. The aforementioned mods will have to be removed. But on a S/C they can stay on pretty much - minus the intake.

do they make an intake to fit te s/c?

makes sense. start with catback, intake for now, then add the s/c

Most people use the larger airbox that comes with the S/C kit. Some say that adding a CAI to the front of the S/C leans out your car a bit - so unless you have a piggyback computer and a tuner available, you should just use the airbox that comes with the kit.

First of all, you're in big trouble if you think we have more than one fuel pump.

Secondly, the stock fuel pump is good for over 300whp - and you will most likely NOT be seeing that number on the TRD S/C even with all supporting mods with the 9.5psi pulley.

Just do this road map and it should save you the headache:

Intake (just for the time being - it'll add a little pep and good sound)
Cat-back exhaust
S-pipe
Header (make sure it won't have future fitment issues with S/C
TRD S/C
upgraded pulley and belt

Then think about things after that. A this point you should be somewhere in the 220-240whp range. If you want to move on from here and get more HP, the next thing you need to look into is larger injectors and a piggyback.

Just do this road map and it should save you the headache:i was very confused on different aero mods/ f/i mods and fuel ratios.

one thing i plan on is a/f gauge

I think that was part of your post when you quoted mine -

This is a good idea. You can even get this before your S/C so you can have an idea what your A/F is before you add boost.

Once you get your S/C you'd obviously want a Boost Gauge - and I would also get an Oil pressure gauge as well.
