I know a SC will give approx 40 more hp and it cost around 3200 ( since I have a 08 ) this of course is the easy way. However I just want to know, power for cost, is this the cheapest or is there another option (like bolt ons) and still keep the factory warranty?

 

the thing is eventhough u put all the bolt ons for the tc, u will not get to the 200hp range, without the supercharger, and if u DO put all the boltons, ull probably be spending around 1000-1400 and just gettin like below 160whp.unless u tune it with some kkind of management, which is another some hundred dollars and wudnt get much out of it neither so....

 

with bolt ons will not retain the factory warranty, the dealer will blame any problem on them.

 

if there is a specific HP level you want to attain, say perhaps anything 200 +, you will need FI (or a LOT of money to build the motor and go naturally aspirated).

If you just want to improve the car's performance a bit and make it more fun to drive, you can achieve that through wisely chosen boltons...which all told you will spend about $800-$1500 on, depending on your level of modification.

If you want to keep the warranty and not have to worry at all about reliablity and the rigors of using FI, then bolt ons is the way to go. Even w/ the s/c, you will want other supporting mods that may void the warranty, and you still run the risk of having engine issues, which even if covered by warranty, is a big PITA.

Imo, 40hp for $3200 isn't worth it. Thats $80 per 1HP....

it all depends really, if you have $$$ to burn...why not?

And no, there is no magic fix for cheap HP.

 

well remember that you're gonna get about 190-200 whp....meaning a 50+ whp gain.....which is pretty significant.......i think the s/c is great bang for you buck if you're not willing to hassle with turbos, etc....wasn't trd sparks selling the s/c for 05/06 for 1800?

 

you won't get 190-200whp with just s/c alone.

right, we've already concluded that you can get around 40hp from the s/c.

the s/c is not hassle free though. plenty of people have had issues related to the s/c.

and btw, he already said he has an 07 or 08......

 

^^True dat. Only dyno of stock SC I've read netted 184 whp.

Make up your own mind, but IMO the SC isn't good bang-for-the-buck, compared to turbo. Most SC'ers wind up adding header, exhaust, 9.5 pulley, and fuel management anyway, which of course bring warranty questions right back into the picture.

And as alluded to, SC has issues with whining, breaking brackets, dealer install issues, etc.

BUT if warranty issues are your main concern, dealer-installed SC is really your only option for adding significant HP.

 

I made 187whp in a stock 06 s/c tc with the ambient temp inside the shop being 95*f, I never dynoed the car after I put the exhaust, but it would be safe to say that with the exhaust and lower ambient temps, say around 70* I could've put down very close to 200whp.

 

I say just wait and save up the money to get a good turbo as soon as the warranty is up.

 

or just save up and get a better car. .....with a turbo.

 

My SC has been trouble free since day one.
As for the aforementioned "Whine", I don't think thats a problem ... its as sexy as hearing turbo spool if you ask me.
My car is pretty damn fun and I enjoy it. I'll be adding the NST 9.5lb pulley when I get around to doing the install and I'm sure I won't regret it.

1tc4u2nv - the dealer can not deny any warranty work because of bolt on's unless they can prove it was the mods that caused the problem.
Google - Magnuson-Moss Act

 

with intake headers exhaust you could get 160-170 whp... if you want to get closer to 200 without foced induction then you need your engine built... and thats another 2-3k...... so not worht it.... go s/c and get a turbo back exhaust, 9psi pulley and you are good to 220-230hp..

 

yes thats right, but they will do everything in their power to blame it on the bolt ons, let me give u an example (this happened to me). One day i'm on my way to work at 5:00am, highway is totally empty, so i decide to make a top speed run. My car was totally stock except for the s/c, so I get the car up to 127mph, after a couple of seconds I hear a weird noise and my car shuts down. I pulled over called the tow truck and took it to the dealer where I bought the car(not where I installed the s/c) because i knew it wasnt a s/c problem, and took all the warranty papers. Well after a few hours they called me and said the s/c needed to be replaced but I wasnt covered becuase TRD said that the s/c pulley is supposed to be black and mines was purple(because you have the s/c, you should know that the stock pulley IS purple). So I had to take it to the dealer where i installed the s/c and the problem was a f***d up MAF sensor.

sorry for the long post, but it goes to show you what dealers will do to a customer to save some money.

 

^^so what happened? they replace it or not?

 

huh?

 

Oh for sure, I'm not disagreeing with you. They will always try to screw you, hence the MMAct. They prey upon the uneducated consumer whether they're selling or repairing. I stopped going to a particular dealer whom my family's been using since 1985 because of this exact reason. I'm loyal to Toyota, not their dealerships.

 

yea when I took in to other dealer, where I installed the s/c, they took it right in, found the problem and fixed it,had it back 2 days later. BTW, since you u live down here never go to headquarter toyota, thats where it happened. Another thing that upset me was that this happened on Dec. 31(on a sunday) and they were gonna be closed until tuesday so I had the car towed to my house and then on tuesday I called the dealer and told them to pick it up...it cost me $125 to tow the car from where it left me stranded to my house and when I asked for a refund of that money the guy said that toyota only pays towing services to the nearest toyota dealer..so I called scion corporate, stated the problem- which was that they refused to fix my car,blamed it on the s/c, told me I had changed the pulley and didnt want to refund me the towing charges- and they send me a check for $125.
