rebuilding the motor is a goog way . like new pistons and etc,

With a built motor with pistons and etc, u will surpass the 185whp he wants. 200whp is within grasp there.

Yep, not looking to really get deep in a rebuild.

It is very close to 200 if you take the following steps, the bolt ons.

1. Cold Air Intake.
2. Header
3. S-pipe, nobody mentioned this little bottle neck.
4. Hiflow cat and new mid section
5. Axle back

Then get an engine management, I used the CAMCON and it works wonders. This little piece with header, S-pipe and Axle back gets you an additional 8whp to 4K and from there to red line 14 whp.

Adding all the bolt on parts is not a guarantee you get the whp that is stated. It really requires a management system to maximize and fine tune the parts you have just added.

Hate to point out that it was mentioned....

Thanks, but you neglected to tell us what kind of dyno numbers you saw with that setup.

soros151

Why not say a complete catback setup? Instead of saying every part of the exhaust system? Or is the s-pipe out of the catback per se?

Okay, so now you're at about 155-160hp. Where's the other 20-25 coming from? Not from your little "camcon." Especially when the Toyota ECU will just overwrite any changes you make given a couple of hours/days.

A flywheel and crank pulley won't get you any power either. I'm not sure why people think they do.

Well you're going to have to get into the shallow end, since bolt-ons won't get you there.

I can show you a dyno of my friend making about 165whp with an Injen intake, alphawerks header, and an injen exhaust. He had no other mods to make those kind of numbers. I'd say with a little bit better tuning, a mid section, and SOME kind of head work, 185 is definately doable. The gentleman that started this thread is looking to do what it takes to make the power, I spoke to him on AIM yesterday. He has an 07 tC which means 9.9:1 compression vs our 9.6:1. So yeah I'd say he has a chance to make a little bit better power when he starts adding more bolt-ons. The only internals I think he'd have to do is headwork, but he doesn't have to touch pistons and rods.

Joe_Dezod

Oh and flywheels can make more hp at the wheels. You're motor's already making the power, but putting less weight on the motor to fight for higher revs will yeild more power at the wheels. So yeah he'd be able to pull off a little bit more power on a dyno.

cool. what's a good flywheel to buy for the tc?

soros151

Fidanza's Flywheel is the most used.

Flywheels don't add power but it'll be less weight the engine has to overcome to complete the same amount of work. Fewer lbs per feet to pull is more ft pulled in one second.

The net result is basically the same as adding more power. But by lightening rotating mass, you're adding "power" to the entire RPM band rather than in just one chunk of it.
