370z MODS!!
 

hey guys im fairly new to the car scene and i want to focus my 370z first on performance then stance. so my question is what mods would you need before doing Revup tune, i dont want to retune so i just want to know what i would need for the most hp.
so far i have
-tomei full cat back exhaust
-tomei test pipes

and im planning on getting
-tomei y pipe
-stillen gen 3 intakes
-mishimoto radiator/oil cooler


so what else would i need besides what i listed ?
i dont know what cams and injectors are or if i even need them. etc so if you guys can please help me out and explain to me these things and what i need to push the most hp with the revup i would love the feedback.

stickers... you need lots of stickers!

Yeah baby! I agree... stickers for wicked jacked performance!!!!

LMFAO i already got my whole bumper filled with stickers. nah nah jk lmfao on a serious note give me actual answers lol.

Depends on the model of your Z, what options it has, and how you define 'performance'...

Base models gets different first mods than sports and nismos because each uptick in trim level includes the things you'd be buying anyway. For example, on a base Z you probably want to look at a LSD - but the Nismo comes with one so no real need unless your pockets are deep enough for a mechanical to replace the viscous.

Then there's the AT/Manual question as that effects the gearing... And there's different schools of thought for track performance, straight-line racing, and drifting...

So - tell us more about what you have and what you ultimately want it to do.

i got a 2011 touring Automatic :? 370z and i mianly want straight-line racing like in the future i plan on putting turbos in the car aswell...

Then I'd suggest gears as that's generally the biggest 'bang for the buck' for these cars IMHO.

See here for the final gears brain-dump.

I'd steer clear of intake/exhaust before FI because whatever you buy now you'll probably change then. If FI is more of a dream-thing, then yeah - allowing the engine to breathe better always helps a bit... But just realize that you're mostly doing it for looks and sound until you go FI.

if you ever want to go boosted make sure it is a stick shift car. if yours is auto, id suggest you to trade it in and get a manual instead

Good point.

Though I hear you can get away with an A/T if you're supercharged as that makes less torque? One of the FI guys can probably yay/nay that for us. :)

ok lets then forget about boost since its hella expensive, since im auto what mods should i have before Uprev tune my car. ( be as specific as possible.)

Tuning is really only beneficial if you're substantially changing the volume of air going into the engine, which requires remapping the fuel flow to avoid leaning out too far and breaking stuff.

On a NA engine, the best it can do is zero restriction on the vacuum the engine is pulling on the intake... And changing the pipes into and out of the engine can only do a couple of percent on that - at best - which is usually within the realm of the ECU to figure out on its own.

That and the VQ is fairly dialed in out of the box... There's just not a lot of hidden HP to find on such an established engine.

So, in generic terms, after buying the license for uprev and paying someone to remap the car you're looking at about a grand for about 10whp and 7tq.

By way of example, the NISMO VQ37 is technically full bolt-on and tuned and only generates an additional 18HP over stock.

You named off some good stuff, Test pipes,free flowing exhaust & cold air intake will gain you about 20whp before tuning & another 20whp after Tune.
Quaife makes the only Helical locking diff unit for your 3.357 gearing diff.
You have 4 very good gears to play with (0-125’ish)
A Sport or Nismo 3.69 gearing diff will help acceleration.
Unless you plan to run e85 fuel - no need for upgrading injectors or fuel system.
Look at Z1’s 400hp Package...it’s got things you have +1.75” primary headers.
Don’t expect to exceed over 330-340 after $$$$ of dollars spent.
But you can at least get down in the 12’s 1/4 mile..,very low 12’s possibly on good air.

Using Quality fuels & having it tuned for it is extremely important for optimum power gains.
Going without tuning is screwing yourself.

On our cars trying to make power naturally aspirated gets expensive quick and will be or exceed the cost of a turbo or supercharger kit. If you plan on a turbo kit in the future for sure then I would skip intake and exhaust since most of all of it will be changed out and a aftermarket cat back exhaust would be the only part useable after you install a turbo kit. I would have to agree that gears would be the best bang for the buck. One mod I believe is a must for all 370Z’s is a aftermarket oil cooler even if you track your car or not it will certainly prolong the life of your VQ engine. I have seen a lot of people dyno tune their 370Z’s over the years. The only time I seen somewhat lean conditions naturally aspirated is if you decided to install long tube headers or run cat less test pipes. If you plan to install high flow catalytic converters or run the stock Nissan catalytic converters don’t waste your money tuning your 370Z wait until after you install forced induction on your 370Z. Naturally aspirated you may see max 10-15 whp and 7-10 whp from my experience.

Read my journal. :eek: To give you an idea about mods. :tup:
