This is what I have purchased to date:

-Greddy Twin Turbo Kit
-Greddy Intercooler
-Greddy Type S Blow Off Valve
-Greddy Turbo Timer
-Greddy Warning Boost Gauge
-Greddy Warning Air/Fuel Guage

This is what I plan to buy:

Borla True Duel Exhaust( any suggestions?) I do not want any problems with emissions.


What else should I buy? I would like to get alot done on the first install.

The list looks good but, let me be the first of many to tell you the Greddy Air/Fuel meter is a narrrow band unit which has limited use (a nice way of saying it provides little to no useful information)
I'm not saying trash it but you should just know before using it.

Also Greddy claims to have upgraded the wastegate gaskets if you don't have the newer gaskets I'd get a set of the turbonetics gaskets, so you don't have to worry about that.

As far as exhaust get what ever makes you happy on a turbo system there is no tuning with exhaust post turbo, here bigger is better. I'd recommend high flow cats the stock ones not only choke off the top end but hurts spool up as well thus limiting low end response. It'll make a large difference for the small cost.

Good luck, I'm sure you'll enjoy it

a boost controller may be beneficial, that way you wont have to control the boost with the wastegates, which will not only allow you to turn up the boost for added performance, but is also safer because you can monitor the boost in real time.

a greddy profec-b or profec e-01 is what most people have been using with the greddy set up.

 

and if you're going to get a boost controller and turn up the boost you should think about getting the greddy ignition harness to retard timing, otherwise you're engine will go boom.

you may also want to get colder spark plugs

 

I'm in the same boat and I have all that you purchased with the addition of the profec e01, EGT gauge (didn't need boost gauge since the profec will display), ignition harness for the emanage (you need an adapter from Greddy to avoid fried coils), and I'm looking to "jet hot" coat a few parts in the engine to alleviate any engine heating concerns. For me to be happy, I want a new clutch, fuel pump, and FPR. Once I finish phase 1, phase 2 will consist of pistons and rods

What is this adapter u r referring to 350G? is this something new that greddy came up with to prevent frying the coils? So far most people are using diodes to prevent excess current from reaching the coils. Let us know

 

The List is a Good Idea..

GQ_626, 350NOW, Wld350Z all have Input on this thread..

Turbonetics Gaskets for sure..

Bolting the complete system together out of the car.. before going under is a plus

AntiSieze Compound on every bolt and Stud.. $5

Count the threads on the studs at the head.. Early kit's were too short and loosened.

Extra studs and Cap Bolt's Grade 8 -

An installation guide by someone who has installed this kit as the Greddy instructions are totally worthless...

A few tool's will need to be re-manufactured to reach parts under car... About 4 feet of 3/8" drive to fasten Bolt's that should have been Studs or Cap Screws.. ( You can see these in the install photo's from Greddy - but not provided.. )

detailed programming instruction guide in English... For E-Manage
and for sure the EO-1...

I'm sure when the people ( who have laid hands on ) reply they can make clear the way to make it easier..

Like one fellow said to loosen the trans mount and engine mounts - so you could swing the engine right and left to get an extra inch of wrench space...

Or like the fellow who removed the engine, mounted all parts and then placed unit back.

A couple of Telephone numbers of the poor "guy's" that have done it..


There are many more.. but welcome to the Greddy do it your self club... It will be a memorable experience !

Cheers Amy -

The diodes are so DC only flows to the Coils.. However the Coils can be damaged by switch to ON position and Not running..

GQ_626 Sharif will elaborate,,, I'm sure...

 

I suspect the "Ignition Harness "Adaptor" is Greddy's way of making a profit off of $3 diodes. With diodes on the ignition harness, you are safe from burnt coils, unless you leave the car in the key-on-engine-off position for too long. The accessory position is fine, but keep it out of the "KOEO" position.

If you get a boost controller, there is only one choice...Profec e-01. It is specifically designed to interface with the Greddy eManage, and is a good boost controller to boot. It's about $100-$150 more than the Spec B, but worth every penny.

Things to check on the kit:

1) Wastegate Gaskets...make sure you have the metal lined gaskets that are included in the newer kits...if not...get some from Greddy or Turbonetics

2) Check the manifold studs included with the kit..make sure they are about 11 threads deep. If not, then I would suggest replacing them with deeper studs.

3) Take a detailed inventory of everything in the kit. Take every single part out of the box, and check it off the inventory sheet. It is very common to have a missing or mismatched part in the kit.

4) Get LOTS of tools. Extra cap screw wrenches, allens, shorty ratcheting metric wrenches are key.

5) I consider the ignition harness manditory, even at stock boost, if you plan on running 91 octane fuel. This kit needs some ignition retarding

6) Walbro 255 fuel pump if you intend to boost beyond 6.5-7psi. That is the point where the stock pump poops out.

7) AEM Wideband A/F guage...not the Greddy...which is narrow band and useless. I also consider this manditory, give the variability of the 350Z ECU.....

Good luck...are you self-installing?

 

I know about as much as you know I did get the harness (haven't seen the price tag yet) and I'll keep you all up to date. I anticipate installation starting in a week.

 

That's a good list, the only thing I would add in item number 6 is an Aeromotive FPR.

Item number 3, should be the very first thing you do.....my install guys were 1/2 way into the install when they noticed that parts were missing or damaged in the kit. Because of this, It took them extra time to install the kit.

 

To all,

Thanks for the replies. I must admit that I am even more confused than before. I have never modified any car that I have owned and will "not" be installing these parts myself. I simply want to get the most done at one time.

A few more questions from the newbie:

-Why does Greddy sell this A/F guage? I just wasted $ 263.00, that is not cool!

-Should I buy a new exhaust? Is there any reason?

-Where do I buy high-flow cats? I want to stay w/in the req. of NJ.

A true dual exhaust will help you get the most out of an F/I application. More air in...need to get more air out.

 

Go with Crawford. http://www.crawfordzcar.com/ That's what I have, plus I like the sound of the cats. =)
