What is your best MOD?

Lowering the car. No single modification offers the improvement to this platform that lowering the damn thing does.

Did one hit with 13Ts, S/steel manifold, precat elims, EK2 downpipe, no cat and HKS superdragger... difference was somewhat noticable in the mid-range!

Very close second was the AP BBK - massive difference and feel compaired to stock!

If I only choose one its Boost controller HKS EVC 6 .

13Ts are hand down my favorite go-fast mod.

My Cadillac Opulent Tuscany leather hides are my favorite non-go-fast mod.

Other notable good mods:
-ACPT 1 piece CFDS
-Tein S. Tech springs (best bang for the buck suspension in my opinion)
-Wideband O2 (any brand will do, I run AEM)
-HHH Datalogger

Maximal solid motor mounts. Best mod by far... Actually the only one that hasn't given me an issue or made me regret it at one point or another..lol

I got mine from discount tire with my employee discount, bringing my total down to about 425. Its easy to setup and use. Running 14.5psi vs. 9psi on 1G TT's will net a very noticeable difference.

Ive seen a completely stock VR4 dynoed at around 200awhp. All the owner did was drop the factory exhaust and install a 3" downpipe (open dp), and netted over 240awhp. Ill try to find the dyno... it was a pretty old thread on 3si. Not to mention the better spool that comes with all the power.

these two upgrades are definitely worth it if your looking to spend a small amount of money on a lot of hp. a manual boost controller can be as cheap as 15 bucks (even less if you make it yourself). Heres a good deal for a downpipe/test pipe combo from IPS (Jeff from IPS is a great guy, and the customer service there is awesome!)

EDIT: here's a comparison link, its actually a test of IPS's cutout downpipe, which is the same as having the exhaust off after the downpipe.
