Good morning all!
I am in need of a little advice going forward, I have an 07 GT with the following mods. Airaid CAI, bama tune, pypes H-pipe, magnaflow exhaust, 3.73 gears, MGW short throw shifter. So I want to go for fun, fast, daily driver; I am going to go forced induction later on but for now natural aspiration. So my question is what is a good next step? I'm thinking FRPP intake manifold and throttle body, or was thinking something more aggressive with cams or cylinder heads? Eventually I'll do both but what is good bang for the buck? OPINIONS PLEASE!!!!!
The intake manifold will actually lose power throughout the bulk of the power band without heads, cams, and long tubes. I'd pass considering it's a $600 part and will have to come off with most FI (not centri).
Throttle bodies are a waste of money as far as modifications go for a mildly modded 4.6 3v. We're talking maybe 2-5rwhp for $200-600.
Most N/A cams don't play well with FI and you'll have to go back to stock or FI cams to have proper performance and drivability. Again, a grand in the bucket if you intend to go FI. Wait until you are FI before dropping a grand on cams.
Heads aren't much of a limitation until 600+ rwhp on an FI 4.6 3v, and you won't see much benefit without cams, LTs, and intake while N/A. Look at 3v heads, you're looking at $2000+ for the pair.
If you're serious about FI, look into Department of Boost. You can be throwing down 450rwhp for around 4k with stock-like drivability using GT500 OEM parts.
To better answer your question, you say FI is in the future, so I would add parts that will build towards that while adding performance. An electric water pump and aluminum driveshaft with CV joints would both increase efficiency, power, and work with FI, so you're not throwing your money away. The most important thing is traction, so look into a set of tires and wheels if you're still on the stockers. I plan to throw on a set of 18x10 Forgestar F14s all of the way around with 295/35/18s on all 4 corners. They'll make much more of a difference than you may think. Also, a quality set of LCAs will help you hook up and handle.
Let us know what routes you choose!
