setup on the car is vibrant 4-2-1 header, catless 3 inch downpipe, k&n CAI, magnaflow catback with no resonator, duel pass endplate, zzp stage 3 heat exchanger, and currently running tvs with 2.9 pully. i will be installing option b and phelonic intake spacer before i change to the 2.7 pully along with new head gasket and arp head stud.

will my stock internals be able to handle it? the engine has 108000 miles on it

 

i bet that exhaust sounds loud as ****..

 

that was similar to my mods a little different and i had a few more things than you. I would highly reccomend meth injection or E85 and u should be good to go. Also a good idea to check compression on your motor or do a leak down test to see what kind of shape shes in. No reason to do the headgasket if theres no issue with it.

 

compression is good al across the board, i dont have e85 where im at and i realy dont want to go with meth i put 4,000 mile a month on the car, its a daily driver and my gas milage car.

and as far as the head gasket i thought it would be to much boost for the stock headbolts, and my headgasket is leaking a little oil.

 

why dont you go read the tvs sticky

 

how much boost is to much for our engine in stock form? i am running about 20psi with the 2.9 and in the winter it hits 24psi. i just dont want to over boost it when winter comes.

and the car also has 80# injectors and a breather setup

 

You only pump meth when you have your foot into it. It won't affect your daily driving. And a good idea to run if you are going to pulley down that far.

 

i understand that, but its another thing to go wrong, and if something does go bad and the meth doesnt work im tuned for it and its an entire day to drive to get the car tuned. and then i have to buy methnol. its just convenient to not go with it. and im already worried about the reliability without meth on a stock motor.

its just a piece of mind thing for me not to have meth, although i would love to have it. if my car is down it costs me an extra $20 a day to drive my truck to work.

you wont find a guy with worse luck then me when it comes to stuff like that.

 

dont have time to read through all the pages. only time i have access to internet is while im at work and i shouldnt be on here while im at work.

 

Pullying down probably isn't a wise decision then IMO

 

so none out there is running a 2.7 tvs without meth? what about 2.8?

 

ull b ok if u get a straight tune and dont beat the **** outta ur car..but meth is highly reccommended

 

im sure some ppl are running a 2.7" pulley on their tvs without meth, but i bet they made sure that the motor was in healthy conditions to handle it. also probably with less miles than your car. if its ur dd and you want reliability just stick to the 2.9.

 

for the amount of timing youll have to remove from the tune going to the 2.7 gains will be hardly anything and will put more strain on your motor. If youre not gonna have the octane stick with the 2.9. It doesnt sound like youre ready to do whats nesscesary and safe for your motor

 

Listen to this ^

 

agree with those two guys ^^

 

so if i did run methanol i would be safe for the 2.7 but do you think the motor would handle the 2.7 + meth or would i be better off staying at 2.9 if i where to use meth?

i realy appreciate all the input guys. thanks

 

Your motor will be able to handle the 2.7" no problem

 

Is this where I sign up for the circle jerk party?

 

You COULD throw a 2.6 on it and be fine.. with methanol or E of course.. but at the end of the day, the tune is what's gonna keep your motor together or separate it /:

ahaahha

 

the car will be profecialy tuned by shane at db performance

so would i be better off buying a meth kit instead of buying an option b and a phenolic intake spacer and then go for the 2.7

 

Most definitely. The phenolic spacer is a real nice piece but not crucial to have. I would run atleast a 10gph nozzle with your set up.

 

Honestly.. You seem pretty worried about something happening to your car..
(not that everyone else isn't)
sooo.. why not buy everything that'll help it? Meth, Phenolic spacer, & dual pass..
Your car will thank you in the end.

 

because im not made of money

 

Okay well get everything first, and then save for a TVS.
