I've been lurking SL for a while now and have been keeping up with stuff since before I got my Scion ( Nov 9, 07) and I'm wondering what I should do.
I've got cai and axleback right now. I know I should get headers but I don't want to get a car that sounds like a big exhaust pipe. I've been thinking of supercharging but I don't know what I should do exactly. I also want to do the whole Brian Cower thing and get new cams and what not.

So what should I do?
Money isn't the main issue as I'll solve that problem in time. I was just wondering what I want to do (nothing halfway doing it) to get the best out of my car and still get pretty good longevity.
Keeping sound in mind, and concerning power I'm looking at
P&P, S/C, full exhaust, new pulleys, pistons, ecu, and cams. What else should I do to get ponies and still take care of my car? Also, based on what you suggest, how many horses do you think I could get up to? (looking to try and get around 220-280 whp).

Any help is appreciated, thanks guys.

 

why dont you build the engine then turbo?

less headache more power.....

 

I was thinking about turbo, if I did I'd probably go with dezod. It's just the only place around here that even touches a turbo is an SRT place

 

ya i mean if your going through all the trouble to build your motor, go turbo... you will be more happy in the long wrong, more power, and should be just as realiable....

 

installing turbo is easy if you know what your doing its getting a place that KNOWS how to tune it

 

I think the guys near me that work on the SRT 4/6/8/10's would be able to. They're a drag team with a gaggle of SRT-4's sitting in their fence and a viper and charger in the shop. I would hope they could tune it right.

So what do you guys think about the Dezod S2, Cower turbo cams, new pistons rods etc?
Besides ecu, what else would I need to keep it running smooth?

 

Definetly do a turbo if you building the engine. You will be wayyy happier. And you wont get stuck saying i wish i had more power.

So if you do go turbo with a built engine and everything i would recommend sleeving the block for more reassurance. LSD would help get all that power to the ground and you will want to upgrade your clutch and flywheel.

Just curious... Do you know how much your willing to spend? Because turboing and ESPECIALLY building a motor is not cheap at all.

 

Thanks. And by the time I do everything, I'm hoping to stay under 13 grand.

 

depending on who you talk to crank pulleys are frowned upon. i personally agree. not to turn this into a crank pulley battle but i'd skip that one. if it doesnt have a torsional damper then it could end up causing you issues.

YES to the flywheel and sleeving. tho and if u plan on going above 300hp and running Drag radials at any moment in time then u may want to look into getting sum axles...thats if ur tryna build a really big beast. our axles arent the strongest on the planet.

 

Yeah, I saw a video of a dezod turbo'd tc losing it's axle on a run. But, it all depends on where I go. I'd probably get a new axle regardless. Definitely if I get t2 turbo or up.

And on the pulleys, I was just saying that as a few more ponies. If it could give me some headache, enough to have someone say not to, then I probably wont.

What exhaust would I need to rebuild? Like, I've got the TRD axleback, and I know you get a midpipe and cat and all on the turbos. Would I need a header? And how loud are the cars after that? I wont mind the hiss, I just don't want it to sound like I'm driving a 66 Mustang when it's just a 4 cyl, I like being able to hear a bit, too.

 

if you are going for big power with the SC then do 3" headerback with a fat resonator or two or a high flow cat or else if will sound like shizz

if you are going turbo then 2.5"-3" TBE ptuning makes one and i think some other companies if you dont want to go custom

 

If you go turbo get a nice 3 inch pipe all the way back from the down pipe and get a downpipe with the cut out valve. Trust me you wont be disappointed if you want it to be nice and loud.
And with a turbo you don't need a header cuse it comes with a manifold.

 

I just don't want it to be ridiculously loud is all.

 

Doing Mods= loud no matter what...all depends on what's rediculously loud to you...if noise is a huge factor u may wanna leave the engine alone

 

YUP the car with just headers and exhaust has gotton me a couple tickets already

 

Yeah, I know it's going to get louder, I just don't want tickets because of it.

 

your 17 bro, i think you should rethink spending so much money on your car/giving it so much power..

 

I completely agree with you regarding the torsional dampener.

But the tc crank pulley doesn't perform that function, as other crank pullies do on other cars.

We have an internally balanced crankshaft. Thanks to the lovely harmonic balancer.
Now some people have removed the harmonic balancer and then plugged/welded the oil hole (for lack of a better term on my part), and have seen really good gains across the RPM band. But I would not recommend this to anyone, lol. I'd rather have the balancer and not risk my engine.

I've heard good/bad regarding pullies. So I wouldn't recommend it unless you are willing to pay for stuff if anything breaks, lol.

I've had it for 40k miles, and zero problems. I guess I just got lucky ^^
But power can be made in other areas.

If you want to make more than 400whp i'd recommend sleeving to be safe.

Up to 400whp you really only need rods/pistons/bearings/head studs/head gasket.

 

I'm really just looking for 300~hp

 

300hp is gonna be more than a handful. Straight from the wastegate is what people usually do but with 300, you're gonna need to put a lot more effort and time into tuning it and others... It's going to run you $5000+ easily.
