Twin Turbo Kits:

Greddy Twin Turbo: Arguably the most common twin turbo kit for the 350Z. The Greddy twins kit has been known to make solid power out of the box. The Greddy Twins come with (2) Greddy 18G turbo's 440cc injectors, and Greddy E-manage. People have made in upwards of 600+whp with the right mods and this kit.

Some of the downside, if any, the intercooler is sold separately. Some might not see that has a "downside". The Greddy kit tops out at roughly 700whp. So BIG whp numbers are not there for those who are going "All Out". The Greddy E-Manage is not a favorite with the Z community. People do use it, but most opt for a UTEC or a Full Standalone.

With a proper kit, and the right supporting mods, people have made up to 630whp with the Greddy Twin Turbo kits.

Fastest Current 1/4 mile time with a Greddy Twin Turbo Kit: 10.375@132.41mph 1.567 60ft (This was with a TH350)

APS Twin Turbo Kit: Another great twin turbo kit for the 350Z, and is probably just as common as the Greddy Twins. The APS Tuner Twin Turbo kit features (2) GT2871R-1 internally wastegated turbos, cast turbo manifold, high capacity oil pan, and vertical flow intercooler. The APS Basic Twin Turbo Kit includes everything in the tuner kit, but adds fuels and engine managment. People have made upwards of 650+whp with the right supporting mods.

Some of the downside, the same as the APS Single Turbo kit, is the turbos. They have the same cartridge problem as the single kit, and some times require replacing. Also, this kit does NOT included fuel injectors or an engine managment. Some might not see that as a downside, because it will alow you to use whichever products you want.

With a proper kit, and the right supporting mods, people have made up to 668whp with the APS Twin Turbo kits.

Fastest Current 1/4 mile time with a APS Twin Turbo Kit: 11.302@124.06mph 1.790 60ft

APS Extreme Twin Turbo Kit: APS’s top of the line twin turbo kit. The APS Extreme Twin Turbo kit has been proven to be “Top-Dog” when it comes to big HP with twins. The kit includes larger GT Series turbos, 880cc injectors, APS Extreme Fuel System, and a 5” think vertical core. People have made upwards of 850+whp with the right supporting mods.

Some of the Down sides, well there aren’t that many; one being the price. This is not for the faint of heart. Expect to pay roughly $12,000-$15,000+ easily for this kit installed and tuned.

With a proper kit, and the right supporting mods, people have made up to 860whp with the APS Extreme Twin Turbo kits.

Fastest Current 1/4 mile time with a APS Extreme Twin Turbo Kit: 11.302@124.06mph 1.790 60ft

JWT Twin Turbo Kit: The JWT Twin Turbo kit has been know to be the most “OEM-like” turbo kit on the market. It makes for a very clean install, and it gives a very small power band. The kit comes in 3 variations; the 530BB kit, the 700BB kit, and the 850BB kit. The kit includes two Cast Manifolds, two Ball-bearing Turbochargers, FMU, Fuel Pump, Spark Timing Control Module, pop Charger w/ heat shield, and Oil Pan Spacer with Oil Return Line Kit. The difference between the kits is the 530BB comes with GT25 turbos, the 700BB kit comes with GT28 turbos, and the 850BB kit comes with GT30 turbos. People have made upwards of 600+whp with the 850BB kit.

Some of the downsides to the JWT Twin Turbo kit is, availability. You can only purchase this kit from an authorized JWT Turbo dealer, and they HAVE to do the install as well. So you’re limited on shops. If you don’t have one in your area…. Road trip! Another thing, and this really isn’t a downside, is the design of the twin intercooler setup. With an aftermarket bumper some find it to be aesthetically displeasing.

With a proper kit, and the right supporting mods, people have made up to 700whp with the JWT Twin Turbo kits.

Fastest Current 1/4 mile time with a JWT Twin Turbo Kit: 11.150@133.41mph 1.938 60ft

Power Enterprise Twin Turbo Kit: The Power Enterprise Twin Turbo Kit comes in three different setups; Complete, Sem-Full, Basic. The complete it contains Twin IHI turbos, high capacity oil pan, 380cc injectors, FMIC, fuel pump, and custom exhaust manifolds. The Semi-Full kit has everything in the complete kit, less the FMIC and oil pan. The Basic kit has everything the semi-full kit, less the fuel components. People have made upwarsd of 550+whp with the Power Enterprise Twin Turbo Kit.

Some of the downside is availability. Power enterprise is not known to have these on the shelf. So there usually is a wait for it. Also it is more on the expensive side. Not as expensive as an APS Extreme Twin Turbo kit, but close. This kit would max out a roughly 700whp, so BIG HP is not a goal with this kit.

With a proper kit, and the right supporting mods, people have made up to 620whp with the Power Enterprise Twin Turbo kit.

Fastest Current 1/4 mile time with a Power Enterprise Twin Turbo Kit: 11.939@116.73mph 1.740 60ft

Superchargers:


Vortech Supercharger:


Stillen Supercharger: Some people prefer the roots style supercharger (That's the one that goes on top of the engine for you noobs), and that is where the Stillen Supercharger comes to mind. The Stillen Supercharger comes in 4 versions for the Non-Revup and 3 for the Revup engines. The Stage 1 comes with the Supercharger with New Upper and Lower Plenums, Install Kit and a FMU Control Box which is locked and it is claimed to give 369FWHP and 305FWTQ. The Stage 2 adds a water cooled Intercooler, Coolant Pump w/ Reservoir, Hoses, and Relays. Claiming 382FWHP and 313FWTQ. The Stage 3 adds a smaller pulley to the Stage 2 and claims 410FWHP and 339FWTQ. The Stage 4 adds a larger 7th injector, Smaller Pulley and an Upgraded FMU.

Some of the downsides of the Stillen Supercharger is the HP/Dollar you get. A lot of people feel you don't get the HP for the amount of money you spend. Also, you have to use Stillens hood with this kit, which a lot of people find ugly. They do offer a warranty for Stage 2 but not for Stages 3 and 4.

Fastest Current 1/4 mile time with a Stillen Supercharger Kit: 13.219@109.92mph 1.984 60ft (Stage 2)

HKS Supercharger:


ATI Procharger:


VQ35HR Twin Turbo Kits:


Greddy Twin Turbo Kit: The kit uses Cast Iron Exhaust Manifolds, Greddy 18G turbochargers, Twin Inlet and Outlet Intercooler, and a Greddy E-Manage EMS that piggybacks on the OEM ECU. Greddy claims it is good for 700+ horsepower. Of course, that would come with proper engine tuning and stronger internals (I.E. Pistons and Connecting Rods).

GTM Twin Turbo Kit: This kit uses nothing but the highest quality of parts. Featuring Cast Ductile Iron Exhaust Manifolds And Turbine Housing, 3.5"x13"x24" Intercooler (Rated for 1000HP), Steering Coupler, Twin Garrett BB Water & Oil cooled Turbochargers w/ HKS Internal Wastegate Actuator's (Standard), and Dual Tial 50mm BOV's. Optional Tial External Wastegates are available They are releasing 4 different stages of this product. Stage 1 featuring Twin GT28RS Turbos w/ a .64 A/R (Rated for 500HP), Stage 2 featuring Twin GT28RS Turbos w/ a .86 A/R (Rated for 700HP), Stage 3 features Twin GT3071 Turbos w/ a .64 A/R (Rated for 900HP), and Stage 4 features Twin GT3071 Turbos w/ a .86 A/R (Rated for 1000HP).

Also, with the JWT kit, there's an instruction manual on the site. There's no way a knowledgeable tech could do the install?

I'm sure there is, but JWT will only allow an authorized dealer install there kit. If you buy a used kit, then the sky's the limit with who you choose.

They will only ship there turbo kit to Authorized dealers. Should the dealer choose to ship it to a non-authorized dealer; the authorized dealer can lose it's account with JWT. The same way HKS controls who sells and tunes the F-Con V-Pro.

Awesome thread Fox! This is very helpful to a FI noob like me!

Couple of questions though,

1) I notice you didn't mention anything about multi-gauge displays. Do you recommend them? If not, why?

2) I plan on getting the Greddy TT kit for my DD G35 coupe. I've been told that it can bolt on to a completely stock engine and using a low boost level (6psi) Do you have any thoughts against or for this setup?

Thanks very much for the advice and again for the awesome thread!

The Greddy TT kit is an awesome setup to start with. Running the Greedy kit on wastegate pressure should be fine on a stock block. Just keep in mind you still have a stock motor; so don't abuse it to much.

As for the multi-gauge displays... are you referring to a triple gauge pod or like an HKS Camp 2?

Don't take this the wrong way, but if you have to ask about gas mileage then you shouldn't go F/I..... but there has been people posting there results in the F/I section.

Turbo Maintenance is a very broad subject. Many people have there opinions on what should be done or what is considered basic maintenance. If I had to say what I thought was important to check; I would say....

1. Check your oil every week or every other week; depending on how much you drive it.
2. Check your coolant levels. Make sure you haven't built up any air pockets in your system.
3. Check all pipe couplers and hoses in your engine bay.Make sure nothing is binding, or getting caught up. Make sure anything next to a heat source is melting slowly over time.
4. Also, I would check your exhaust. From a cold start, turn on your engine and let it idle. Watch your exhaust for any smoke coming. Bring it up to normal operating temperature, and give it a couple revs to make sure no smoke is coming out.

Also, ALWAYS MONITOR YOUR GAUGES!!!!!!!!!!!!!

Thanks for the quick reply! Actually the multi-gauge i was thinking of is made by ARK.

http://www.arkdesign.co.jp/inf/product-ele.htm

I planning for my setup to be a "sleeper" if you will. So i'm trying to avoid the gauge pod on the A-pillar.

And to your point about abusing the engine. Yes, my friends have told me not to drive it hard all the time and don't raise the boost even though i'm sure th bug will bite and i'll want to.
