Default Why not FAST 78mm

I have a FAST 78mm Intake and tb. Would it be worth upgrading to the 90 FAST intake. If so, what 90 tb should I get? Also, I've got an SLP maf. Is that ok? I'll be putting Kooks long tubes on within the next week.

I see you have Heads, but no cam listed.

It's a tough call. Lots of people are going 90/90 due to some impressive gains posted.
If you had a cam, I'd say SURE! But, you should be fine with the 78/78 combo for now. Some tuners can deal with the SLP MAF, others insist on the stocker.

I have a cam with what I think is .581 lift. Other specs unknown.

You need to find out the duration (not for the intake selection, but for your own knowledge). It's probably a 224 duration cam.

Anyhow, slap on the LT's and see what your numbers are. I'm sure you'll be satisfied with the setup. In the future, you can always go 90/90 as an option.

Anyone know anything about this?
