370ish whp, do you think it can be done?
 

Hey guys,

I love my Z, sure if you look through the forum you'll find a few guys with issues, complaints, and such but I'm an absolute fan. So my build buddy and I have been thinking, how close to 400whp N/A could we get? Fast Intentions is coming out with a great part in the LTH and will free up some power otherwise lost with a headers/test pipe combo. Add a good true dual, intakes, pullies, clutch/flywheel and most importantly a great tune I think 350-360whp if not more is possible. So I figured I'd get your opinions, feel free to post any ideas or theories short of F.I. that could help!

Not possible, have to go FI.

Maaaayyybe a stroker kit and $15k will do it, not likely.

It could be done but not at a cheap price. You might as well buy a supercharger than try to go NA. It would take more than what you have listed to get to 370 to wheels. Even with agressive tunes and crazy timeing of the motor you wont get to those numbers with the parts you listed. Thats if you talking 370whp.
Go forced induction bro, you drive a nissan.

so 330whp at most for NA? i am just guessing,

Yep, we had a discussion in the premium section about this and with a NA 370z you can probably get 340 to the rear wheels before you start spending to much money and should just got forced induction.

I'm hoping to go F.I. but I was thinking I might enjoy this summer N/A, I'm going to wait till a few people have the upper stages of the GTM and Stillen kit before I jump in. I believe that atleast one if not both can get me to 500whp.

The Stillen kit should be able to hit 500whp, question is whether the engine will be able to handle it. We're going to find that out sooner than later when Stillen releases their race and tuner kits.

If you are going to stay NA this summer, my suggestion to make the car that much more enjoyable is to get a lightened pulley and flywheel. Make that thing rev!

I agree, that is my plan while waiting to do FI.
Still need that damn oil cooler, but pulley and flywheel are on the hit list.

are the NST pullies worth it? Granted they aren't expensive pieces, but you'd still have to either pay or an install or rent a pulley pulling tool and a new built, seems kinda useless for 5whp.

I don't have them so I obviously can't answer from experience. Pully swaps are really more for quicker engine response rather then higher HP. Also you don't need to rent a pully. You can buy them for 7 bucks.

still can't justify getting them, maybe after i finish the exhaust, cf work, and clutch/fly I'll revisit the idea.

I hit 'yes,' before I realized he's talking wheel hp. I think you could do 370 hp at the flywheel, n/a, but it would take a lot of work and money. But not wheel hp. So I guess my answer is 'no.'

I started at 250whp and im now at 310whp. Thats 60whp over, even if we went 1 to 1 hp to whp, starting from 330 I'd be at 390. So yeah easily possible to do 370 bhp.

yeah, easily done at the flywheel, no way at the rear wheels without massive infusions of cash.

With my mods, the long tubes + pulley, and re-tuned, should be able to get close to 350. That would put you over the 400bhp range, then you might stand a fighting chance against the new 5.0 Mustang, im looking forward to giving it a go.
