Someone give me the low down. I know I need bigger injectors, 60 lbs are just as good as the 42s.
Do I go with a 3.0" pulley? 3.25"? I'd rather be on the conservative side if need be.
My stock fuel pump will keep up or no? Is a walpro absolutely necessary?
I have a stock cam/rockers as well. Will they hold up?
This is my DD and I'm still paying for it so I really don't want to break anything but I've been wanting to do this for a whole now.

This info is out there, somewhere.

Got my questions answered with the exception of the stock cam/rockers durability. Got an iffy answer on that one.

Cam is billet steel.
It ain't going anywhere.
Rockers will be fine, often used in many very aggressive setups.
The needle bearings will eventually wear out and have excessive side to side play, but that happens no matter what you do.
It seems stock rockers are the ideal solution for just about any setup with a cam.

they do not relate to each other in the sense that you are worried about... dont forget your tune homes...Originally Posted by Ultra440

start with 3.4
headers?

3.4" on E85?
luel.
Who wants a 4.8" on a stock L67 car. Solid comparison.

timing > pulley, didn't you say that yourself?
10-03-2012
Timing > Pulley when you make more than 2 psi, guyguy.

You would be pushing your luck below a 3.2. Make sure you have your AFR dialed in, E85 blends change with the wind.
Good luck!

You need to own a tuner, or have a E85 station readily available and then say goodbye to road trips. I would also get a wideband.

This because crappy 3800 heads.
So, HPT, WBo2, E85 and some jerry cans in the trunk, and get a second car for traveling.

My girlfriend has a slightly better mpg in her Acura so we usually take that anyways. BUT my tuning guy said just get another PCM and I can have one tuned for gas on my 3.5 and one tuned for e85 with a small pulley. Keep the PCM in my trunk just in case.
I make frequent trips around Ohio and I've already looked into e85 stations around my destinations and I'm good.
He also said if he can get an a/f around .75 the 3" will work but to bring a 3.2 JIC. I may just do the 3.2 to be on the safe side. Maybe a 3.1.

As far as the widebands, I don't know too much about them. They go into an o2 bung and read out on a gauge in the car? How much $ do these typically go for?
10-04-2012
Depends on if you want crap or something worth getting. If you want a good one like 150-300 dollars depending on brand and if you buy used or new

Does the aeroforce gauge have wideband inputs?
Or is it a totally seperate gauge?

You want to google ntk afx vs aem.
10-04-2012
aem ftw
10-04-2012
If you google the term, AEM FTL.
NTK AFK or bust.

I wouldn't go lower than a 3.2 there, period.
