I agree with that.^^^^^^Add 4:08 gears & you can compete with/beat street Camaros & Mustangs. Also you'll be driving an all around great sports car.

OP, what are the thoughts behind your question? Are you debating the cost/benefit or thinking about skipping NA mods for FI?

If you have no plans to go beyond N/A mods, a car with 4.08 gears and intake/HFCs/catback and tune would be a hell of a lot of fun.

Here's my two cents worth. May not be worth that much but that's what I'm charging.

1) Nissan is already getting just about as much out of the engine as can be done (without damaging itself). The days of major power gains with simple bolt-ons is over. If you want substantially more power, you need a turbo or supercharger.

2) Almost all after-market parts for the Z are expensive. Small market, lots of engineering required to improve on what the factory has done, &c.

3) Mods are not necessarily additive and can, in some cases, actually work against each other. Eg, if mod1 alone gives a 5 HP boost and mod2 gives 10, the two together probably won't give a 15 HP boost. You need to do a lot of research to make sure your mods play well with each other. You can't just throw the "best" components together and expect everything to work right.

That said, it's your car and money. If you like mods, go for it! Just don't be expecting much in the way of power gains without spending a lot of money.

Best hp per dollar...the the370z.com decal! I haven't dyno'd it yet but I am pretty sure that's what I feel in my *** now. That or it's gas.

Don't forget the performance increase from decreasing rotational mass. The biggest performance gain my car has gotten was dropping 8lbs off each corner with lighter wheels and tires. If I can find some weight listings on aftermarket rotors I think even bigger gains could be had here.

I noticed that much more than the intake/exhaust or sway bar/endlink/springs combos - although I will say replacing the broken end links with SPL ones allowed me to tighten the swaybar (actually re-attach it) and that made a BIG difference in cornering speeds vs running with broken stock ones (and one not attached). Not necessarily a power increase but definitely allowed me to keep the car in the power band through corners much easier.

but I believe in this case the right tune makes the difference, of course if you are willing to take your risks with a car still under warranty.
The right tune coupled with CAI, LTH/TP/HFC, catback will give you good fun (and sound). No miracles unless TT or SC tho.

Z370Z011 · 09-06-2013, 10:49 AM

With full bolt-ons and a tune, most people seem to hit the 300-330 range. I've seen one member hit 340 but I think he's the only one up there.
And as most have said, parts for these cars can get pretty pricey fairly quickly.
Anywhoo, Enjoy car

Chuck33079 · 09-06-2013, 10:57 AM

Used parts will bring the cost down a whole lot. I'll bet you can get intake, cats, exhaust and an uprev license for less than $2k fairly easily. Add another couple hundred for tuning and you're good to go.

Excellent point.

A good tune is a must-do to get the most out of any mods.

If I had a tuner anywhere nearby (difficult enough to find a good service department around here - forget anything "exotic" like tuning), I'd get my DD tuned just for the potential efficiency bump. Still considering a remote tune, but not high on my priority list at the moment.

Z1 has 349WHP on E85

there's also that route, if you stock the forum long enough you can get some pretty good deals

I asked the question just to get other people's results. I am located in Australia and the dyno's that we use are different from your dyno's so wanted to get the % gains as a good comparison to where I'm at. Also I am a tuner with a dyno and can test things out. My car is a 7at which made 183kw at the wheels standard, I'm currently up to 221kw with my current bolt on parts and custom tuning. I will post up dyno graphs for each mod on Monday when I'm back at work. For all those that also think NA is a waste I have two turbos ready to go on in the near future but wanted to see what the gains were NA as starting point. Cheers dave

You're pretty spot on with that estimate:
$800 ark grip
$300 FI HFC
$300 Takeda CAI
$500 ECUTek w/ lifetime tune
$1900 total - everything brand used except the ECUTek

WHAT!?
