GTM MHI Kit Group Buy Participants...
 

So, I agree with a lot of people that have stated we should start a thread to see who is still in it, who has paid, in what order, and what options did you go with. So here it is. Please only post if you are involved in the group buy so its easier for everyone to read through, and I'm hoping this doesn't turn into the MHI release thread or get locked... lol.

- Have you paid (fully or partially), and what number are you?
- If you backed out, post your refund status and what number you are.
- What options did you go with for the kit?
- What supporting mods did you buy, and are you doing the install yourself

For me...
-Fully paid #36
-Garrett upgrade .86 a/r, IWG, black powder coated intercooler piping, Uprev
-FI CF exhaust, FI test pipes, CSF radiator, Z1 25r oil cooler, prosport oil catch can, gtr plugs, fuel pump wiring mod, defi boost and a/f gauges, clutch after the stock one goes, doing the install myself.

Fully Paid (July 1, 2013)

Big FMIC upgrade


Southbend Stage 2 Endurance Clutch
DXD Black Flywheel
HD CSC
SS Clutch Line
32 Row Oil Cooler
CSF Radiator
Greddy New Profec OLED EBC
Hks Plugs
Z1 Testpipes
oem exhaust manifold gaskets

Utilizing oem nismo exhaust for stealth/noise concerns.
Low boost for dd reliability.
Aiming for 430whp.

Well done Nismo! I started a similar thread over on myg37.com about 6 months ago but didn't get a huge response unfortunately.

Fully paid back in May before the $AUD crashed.
Was 50 on the group buy list but according to Sam I was one of the first 5-10 who paid...

18G turbos (changed to Garretts with 0.86 housings now thanks to GTM's kind hearts)
IWG
Ecutek etune by GTM (possibly get someone to dyno tune a little in the future)
Greddy Profec Oled already installed in the ashtray (perfect fit for stealth look) - will run two settings 6-7psi for normal driving with 10-11psi option for traffic light GP and local club runs
GTM test pipes
GTM 25 row oil cooler
GTM transmission cooler
Transgo valve body upgrade (5AT)
GTR Plugs
Greddy multi D/A gauge with oil pressure, oil temp and water temp (might add fuel pressure and transmission oil temp down the track)

Already have full FI 2.5" exhaust and HFC's (which will be removed obviously)
Thinking of ceramic coating or heat painting the hot side of the turbos and the exhaust manifold to keep temps down. It gets damn hot here in Perth in summer.

Future mods:
Larger radiator (depending on how temps look post install)
Coilovers (not sure of brand yet)
Front and rear Swaybars
Front strut tower brace
DBA slotted rotors and new pads

What are the fuel mods that a couple of you have mentioned?
Full return system or something else?

M3chhawk posted a really good DIY to upgrade the wiring and add a relay. With the extra power we're putting through the pump, it sounds like it's a good idea to make sure the wiring can handle it. Thought it would be a good precaution to take...

The thread is called "DIY: build and install fuel pump relay and harness". I dunno how to make links using the app on my phone, but you can search it. It's a good read.

I know I'm not a part of the group buy, but can I jump in with a question?

Why wouldn't you go with the upgrade to the Garrett GT28 with the larger housing?

Thats a very good question.

I guess that the 20G would potentially be good for more power than the GT28RS with 0.86 housing but only once you are trying to push BIG, BIG power numbers, at high PSI (20+) and building your block. Apart from theoretical final HP number, the Garretts being ball bearing are a better option for our engines so you'd be pretty silly not to upgrade to them.

Nothing wrong with MHI turbos though. Plenty of Evo's run them on high boost and would smoke our boosted cars all day long!

So am I the only one holding out hoping that ECUtek comes out with Boost control? I was looking at the Greddy PROfec one too. Looks like a really nice unit. Maybe I'm too big of an optimist... But I don't know if I want to be the first guy to do it even if they ever come out with it... Ha

At this point, all of the ECUtek promises are vaporware.

Fully paid since day one, #20 when I spoke up for a spot (I think? I'm sure I'm far up the list for the first ones since I paid quick.)

Here are my kit options and supporting mods:
-Garrett GT2867R .86 a/r upgrade
-External wastegate and 3 inch downpipes
-Tuned with ECUTek
-HKS Hi-Power exhaust (planning to have a shop weld in a reducer to mate the 3in DP to the 2.5in flanges)
-HKS EVC6 Electronic Boost Controller
-Prosport Halo Analog Wideband
-Southbend Stage 3 Drag 6 puck sprung clutch and DXD Black 19lb flywheel
-ZSpeed HD CSC, as well as my own custom one-off Master cylinder upgrade
-Volk Racing RE30 19x10/19x11 wrapped in Potenza RE-11 245 f / 305 r


I'm also planning on doing:
-GT-R plugs
-34r Oil cooler kit
-Upgraded power steering cooler
-DEI gold wrap and sheathing for all intake tubing and cables
-Ceramic coating on all cast parts

I'm shooting for a max power limit of 550 whp. I feel like this should be possible, no pressure, on ~10 psi or less. Less being better. Of course with 93 octane.

I will be handling the install myself, over a period of a couple weeks. It's great having a beater car to get to work and school. :tup: I want to really be thorough with my install, and do every meticulous thing I need to do before I slap it all together and fire it all up. Efficiency is the name of the game.

Alstann, you gonna be drag racing your z a fair amount, or do you just need the 6 puck disk to hold that 550hp power range?

I actually plan on doing various things with my car - there were several reasons why I went for the Stage 3 Drag 6 puck. Before my stock clutch went out, I did many things with my car - including plenty of spirited driving, drag racing (and powershifting through gears), and some amateur drifting as well. When shopping for my clutch and flywheel, I wanted to purchase something that could hold the power of a twin turbo setup reliably, be able to withstand heavy abuse, as well as be daily driveable.

Even though I don't drive my Z every day, my plan for my build is a car that you can simply get into, start, and drive no fuss, no hassle. Basically like a very powerful, OEM+ car. The 6 puck mated to the 19lb steel flywheel matched all those requirements for me. I'm sure other clutches, including full face can hold the power fine, but I wanted the feeling that I would NEVER have to worry about my clutch not being able to handle anything I throw at it. Plus, the 6 puck is not bad at all to drive.
