Uhhhhh no. Is this a 300 or 400 were talking about here? Either way neither one of the will make 360-380whp while still normally aspirated.

Wah?? Nowhere close to anything like that is gonna happen.

You've got some searching to catch up on to find out what you can do, get ready to be severely disappointed. Keep in mind the M2 exhaust probably added approximately 0hp so you're asking alot from a couple more mods.

If you serious about wanting 380hp then it is possible, you'll just need one of these. Get your checkbook ready...

It's a GS4. I was referring to HP at the crank, not the wheels. I already kno that those parts won't get my anywhere near 360whp. Im jus lookin to add bolt-on performance parts

By my estimates, you are looking at an additional 125hp. You should go for it.

At 380hp at the crank you'll put down around 320 to the wheels. A stock 400 will put down 250ish to the wheels so with only bolt ons you will need a small dose of nitrous.

Very interested in how your estimating logic comes up with 125hp. You must know something that the OG 400 guys here that have been-there-done-that and spent the money and actually dyno'd the available bolt-on products and have taken the time to document the results in various threads for everyone the search must not know about. I'm sure everyone with a 400 would love to hear where they can bolt on this kind of power so easily.

Oh and yeah, like mentioned about some spray can help get you there and has been done plenty of times.

If I had a UZ, I'd less concerned with the big numbers and looking into ITB's cause it's the ****ing jam.

maybe its a way to justify your purchase?

IMHO wanna make good power? save the money and get a 2jz-gte.
