2300 spent on parts, maybe. but it's not proven power and doesn't include prices for install and dyno tuning for the piggy-back. planning to do the head swap yourself or pay to have it done?

 

I think it would be more like this:

Check this out:

ebay intake-$100
pulleys-$266
DC sports header-$288
e-manage-$265
exhaust -$210
ZPI stage 1 head-$ 550
ported throttle body-$150

total:$1,829
This one is for all of those who doesn't have like $2,800 for a N/A setup.

 

It will probably be around $2300 for me cause I can install all my parts, except dyno tune which would no more than $100-200 dollars.

 

I believe your setup easily does 200+ whp and mine does around 190 to 205ish...well you get it... lol

 

Anyone have any idea how much hp porting and polishing the head will give you? And the throttle body as well.

 

Hmm...^^^was wondering too.

 

Not a lot, and less.

At least that's my guess. It's been discussed ad nauseum over at YSTC.

 

is there some numbers?

 

just for reference I use 93 oct. on my everyday tC and it's not FI!! it only has the TRD exhaust!!

I'm feeling more the N/A setup better than FI, maybe just me!!!

 

You're wasting money.

 

Congrats on paying $10 more per tank than you have to, I guess

 

it's been 2 years with the car and I don't think it will respond good if now I decide to go 87 or 89 oct. So with that said I plan on keeping it at 93 oct. Plus here in PR I don't know if it's me or what but I do feel a diference bewtween both oct. in the tC I have driven a friends car with 89 oct and it does feel diferent.

 

You're hallucinating. Switching back won't do anything.

 

Yeah, I was always told once you go up to premium, it's not good for your engine to go back. I could be wrong

 

yes, you are.

 

Sorry to say to TRDTCPR but changing to 93 octane won't do anything in the hp department. It is just harder to ignite and good at keeping detonation probability down. Waste of money and proven. You can search any octane thread here in SL. Sorry, but that is plain money wasting that if you saved, you would have a good header by now.

 

Actually 87 or 89 if you want is better for your car... And it will give you a couple of hp more on the dyno (provided you are N/A) lower the octane the easier it burns... I used to be a fan of 93 on the tC my self until I was proved wrong, (yes I dynoed it) Not that it makes a significant difference in power but like people said above, you are just wasting money... Oh and you can switch between the 2 without problems... Back to topic I dont think all those NA upgrades will give you roughly 60 more whp... lol @ ebay intake $100...

 

If I had the money, I would go tomorrow to Dyno my ebay intake, just for the fun of it and to see at least 3hp gain.

 

Watching. I would also like to do this. So someone needs to make 200+ whp n/a..

 

like the others say, you should take that quote back
i'm 4 cylinders here just like you guys, but even my car handbook says to use premium.
