Hey guys well i know that SC wont be coming out ne time soon, so im going to take some of the money that i had for the sc and buy some performance parts, i just ordered my short throw, i have like $1500 left to spend, in know im going to get headers intake, full exhaust, ne thing else you guys can think of, Lowering springs?

 

well if you aren't going to be running any kind of forced induction, i would recommend a set of high compression pistons, and a ported throttle body. I hate to say it, but you could set up a nitrous system. Light-weight rims wont hurt either. I'd say the best performance upgrade for your buck at this point would be a great set of tires.

 

how much do high compression pistons cost, what exactly does a throttle body do?

 

high compression pistons can range anywhere from $700+, the more compression you run, the more power you make. A throttle body is what the air passes into to get into the engine, the wider the throttle body, the more air that gets into the engine. more air = more power.

 

if you are planning on ever going forced induction, those pistons are a waste of money until you get your Forced induction. My best advice is to just put that back into your account and sit on it until you have enough to buy the sc, or a turbo kit. cause if you are ever going to do some forced induction. H/I/E will be replaced and you are gonna want forged rods, piston heads, sleeves, and a head gasket for your forced induction. you will also want to blue print your engine and lower the compression ratio to accomodate more boost. Fuel pump, brakes are gonna be a must. So with your original dream of forced induction in mind and since you don't want to wait for the component, I would recommend you either do your suspension (shocks, sway bars, springs) your clutch and flywheel, or your brakes.

 

are you sating that if i get intake headers and exhaust it will need tp be replaced if i ever get a SC?

 

H/I/E will not be replaced with the supercharger. maybe the intake but we dont know. H/I/E and springs and rear sway bar is the way i would go. you improve power and suspension.

side note: why would he buy pistons and such when he stock.............that makes no sense at all. you gotta crawl before you can walk.

 

well, you can still stick high compression pistons in there if he wants to make more power without ever going FI. They will still add power wether or not he has anything else added on.

 

With about $1500 to spend, this is what I would do (along with the short shifter):

-TRD Suspensions Package (Springs, Shocks/Struts, Rear Sway Bar) $690 + shipping

Approx: $735

-225/45/17 Pirelli PZero Nero M/S (great all season tire) $565 + misc.

Approx: $1320

-Axxis Ultimate F/R Pads (aggressive street pads) $125 + shipping

Approx: $1460

-Stoptech SS Brakelines (front and rear) $148

Approx: $1608

-Motul 600 DOT 4 brakefluid (better wet and dry boiling temperature than stock fluid and ABS compatible. about 5 bottles) $65

Approx: $1673

-Mobil1/RoyalPurple/etc 5W30 Synthetic Oil (continuous investment)


You wouldn’t gain any horsepower, obviously, and its a little over $1500 but you'd still have an aggressively performing street machine, that's truly ready for some power upgrades. Despite no power increase, you'd still probably be able to take any stock tC off the line with those improvements and well as in the corners. You might also want to consider replace all of the other fluids with synthetics (coolant, power steering, clutch, and transmission).

 

Ya i would love to do all that but then i would have to install it, i dont know much about cars, so i would most likely have to spend alot more $ getting it installed. So im leaning towards header, full exhaust and intake, and then trd suspension

 

If you get the supercharger your intake will most likely be replaced by an intercooler. your exhaust will go. 2.5 is the largest you wanna go with a n/a vehicle. Once you go forced induction you will want to go 3". If you go 3" on your n/a tC you will loose low end torque. Basically once you go forced induction the characteristics of your aspiration changes and to achieve the most power you will need to buy parts to suit your engines new needs. You could buy those parts b4 your forced induction system, but on a naturally aspirated vehicle you will most likely lose power with the set up for forced induction.

 

Get your clutch, flywheel and suspension done. Your car will benefit from those modifications N/A or forced induction. a lighter flywheel will increase acceleration and torque at the 3k + rpm range. and the stock clutch on the tC is garbage anyway.

 

the intake will not be replaced by an intercooler. Intercoolers are generally mistaken as cooling before it enters the intake, when its actually after.

 

^^^ your right. But the topic isn't "Forced Induction, Intercoolers, and You" its what to buy. And if he is deciding to go forced induction I/H/E will be changed or replaced. Because the needs of the engine change and you will need to adjust to get the most power from it. In a nutshell, if you are really serious about tuning your car with forced induction 1,500 bucks is not close to what you want to spend. I really recommend just saving your cash man. Just some food for thought. A good stand alone fuel managment system will cost yah 4gs easy.

 

well if he is staying SC, he doesnt need to replace his headers, intake or exhaust, if he is going turbo then thats a different story.

 

That depends on the boost he wants to run. 2.5" exhaust is cool for running 6 psi i guess, but if he wants to run 10 or even 8 psi I'd definitly get the 3".

 

I say suspension first...

 

so if we take the tC and install a supercharger we would have to change the exhaust? i was thikning of getting the TRD exhaust and then SC when it comes out.

 

you should be fine going 2.5" for the SC. even up to 10 psi.........any higher and you might wanna upgrade.

 

You could bolt on a super or turbo charger to the stock exhaust (san the exhaust manifold for turbo applications). However, you'll see far greater performance gains if you have a larger diameter exhaust. If you replace everything from the header on back, using 2.5" piping for the exhaust, and then add the supercharger you'll be fine. You do not have to step up to a 3" exhaust. But, by doing so you would see an increase in power. That said, using the TRD exhaust will grant you nothing, with or without the supercharger. Regardless of if you get the supercharger or not you'd want a complete exhaust system that replaces everything from the header flange on back if you're looking for an increase in performance. That means a kit with a replacement S-pipe, high-flow cat (or deletes the cat), mid-pipe, and axle back/muffler section. The 3 or 4 kits that include all of those parts all use 2.5" piping.

Regarding the intake, if you plan on buying the supercharger, do not buy an intake right now. Neither cold air or short ram. Yes, a supercharger can use an intake, in fact, there are pictures from Scion with the tC supercharged with a CAI, however, the intakes that are out now may not fit properly with the supercharger. So, unless you have money to burn, don’t take that chance. Just wait for the supercharger and then research what intakes will fit properly.
