What else am I missing?

[addicted4life]

Hey guys, so some of you know about my build and how large it has gotten up to. I am talking to specialty z about ordering the remainder of what I need in about 1-2 months. Can you guy just start listing off internal parts, motor parts etc that I know I wouldnt have thought of? Example is the idler stud, why is it always done in builds or why i would need it, etc
I realize this may be a little vague haha i just dont want to have to order things one at a time while its being built. My buddy is building it back home so trying to make it as easy as I can for him.
EDIT: Should also say I dont want to push more then 25psi on race fuel. Whatever hp I make is what I will be happy with. Would like to run low to mid boost (13-19psi) on the street under normal conditions. It is a twin turbo, fmic, single log plenum w/90mm throttle body, map sensor, external wastegates, haltech, etc.


The parts I have so far:
Two (2) Precision 5454 turbos, .63 a/r
Specialty Z Inconel manifolds (to be modified for external wastegates)
Two (2) Tial mvr 44mm wastegates
FMIC 2.25" in, 3" out (27x10x3.5)
Tial 50mm bov
Infinity Q45 90mm tb w/tps
Complete OEM gasket kit from Nissan dealership
Mishimoto TT radiator
Water pump
Timing belt
Walbro 255 fuel pump (to be sold or doubled in fuel setup)
Bearing kit
Wossner pistons 8:1


Relavent parts on the car prior to build:
3" straight through exhaust, no cat, no resonator (will be from turbos back)
ACT HD 5puck unsprung clutch (good to 553 ft/lbs)
AEM wideband & boost gauge
Lowered on Bilstien shocks & coils
Turbo timer (for sale now I guess)
HKS EVC 5 limited black (for sale as well, $350)


So far I have on the order list is:
Haltech with all but one accessory (egt, intake temp, dual wideband, boost, map, i/o box)
Custon harness from Wiring Specialties
ARP headstud kit (L19 w/nuts), (Do I need full kit or just headstuds?)
Eagle rods
Electric fan, Taurus SHO
1000cc injectors
Intake plenum and custom rails from these guys - http://www.rossmachineracing.com/intakepartspage.html
Fuel setup, not sure what to run here, twin pumps now I believe but whats best?
My Exhaust is custom 3" with Hpipe but I'm now seriously looking at the new Z1 3" PG exhaust after their new video release (if I can get it working on my 2+2)
Charge piping

Added as per NICO suggestion:
BDE exhaust rear block offs

Feel free to chime in, any advise will help thanks guys

So then I'm not missing a thing am I?

[gsrteg]

how much power you want to put down the to wheels?

[addicted4life]

Honestly, whatever I get ill be happy with so long as it runs smooth and safely. I have turbos good to 1000hp and it will be able to breath very well.

Edit: But to answer your question about 600 at moderate boost, I'm not going to push it above 25psi maybe even 23 or 24 just so I can reach a "magic number"

You should get this: https://specialtyz.com/shop/300zx/bde-e ... plugs.html

Also you need to tell us everything you are getting and everything you plan on getting (from gaskets, to turbos we need a complete list in this thread) so at that time we will be on the same page as you and can fill in the blanks.

For the studs, You should look into L19 head studs/nuts. The eagle rods come with ARP rod bolts.

[addicted4life]

Ok thank you Mark I will update with what I already have.

[300ZXttZMAN]

No problem man,

If you want an E fan look up the Ford Taurus SHO fan.

The stock TT pump in good condition is good for 700hp. Just buy a new oem one for extra insurance.

[addicted4life]

Yes I've heard of this Taurus fan from when I used to rock crawl in my jeep, I wasn't sure if something better had been developed by now. As for the fuel pump, your saying just a single new OEM pump will be fine? Would it be that much extra to add the walbro 255 inline with a new OEM to ensure there is no drop in fuel pressure? I ask just because I have it now and it might only be another $100 for the dual setup parts. I will be using braided stainless line as well. What about a regulator? The nismo one or is there a better unit for my needs?

Thanks

[300ZXttZMAN]

OEM fuel regulator will be fine.

The OEM TT fuel pump is a beast. There are Supra guys that run our pump because they are quiet and reliable - especially when bought new.

IMHO The best fan is the OEM TT fan, fan clutch. I think it flows like 5,000 CFM or something close to that.

1000cc injectors are over kill. For our cars the CC of an injector is roughly the amount of power it can support. But then again your build is going to a map sensor as well as a couple other changes to the factory TT plumbing so the common rule of "CC of the injector roughly equals the amount of power it can support" might be thrown out the window.

I'm willing to bet that your build will actually be less efficient than stock in terms of the intake design - the intake system for our cars was actually very thought out by Nissan's engineers. But it will be interesting to see if any gains were found.

Good luck.

After looking for injectors and deciding to go top feed with custom rails, we saw the ID1000s as the best bang for the buck in quality and performance. I can get used 6 used Siemens 880 11mm injectors for $350 from a friend back home but I don't know much about that brand.
Ok, I will return the pump then and look for a new OEM unit, a single install would be easier then the double anyways haha

The intake will be carefully planned out too to make it as efficient as possible with flow design, the guys I have doing it while I'm away are quiet experienced in building motors.

It will be different and I am quiet curious to see how it comes together as well. I've always done things differently, that's just how I am I guess haha


Is there anything else anyone could recommend?

[300ZXttZMAN]

An upgraded oil cooler would be cheap insurance - you should consider. haha.

[addicted4life]

Yea I was on the fence about an oil cooler. Messaged a couple guys about their used ones for sale but no one came through. Ill keep looking for a used one. 10 row should be fine eh?

[nissanfreak12]

Yes I've heard of this Taurus fan from when I used to rock crawl in my jeep, I wasn't sure if something better had been developed by now.

You could also look into the Lincoln Mark VIII, its a two speed and pulls a LOT of air with less electrical draw, I think the same if not more the the SHO fan, friend back in Phoenix had one on his Z, I was pretty impressed.

Cool I will look into it's flow volume on google, thanks for the input.


Do I need the complete arp kit or will just the L19 Headstuds be fine? 25psi MAX and that's on race fuel

[300ZXttZMAN]

Yea. The stock one just isn't very hefty enough IMHO - not for larger builds atleast.

[addicted4life]

Ok cool I think I found an oversized oem one off a V8 car, just checking specs to see if its worth using.


As for the ARP gear, would I be fine with just the headstuds or do I really need the main studs as well?


Really though, anything anyone wants to throw out there let me know!!!

[300ZXttZMAN]

I'm just running the ARP L19 headstuds and nuts.

[addicted4life]

How much boost do you plan on running mark? tops on race fuel and street if applicable.

What about sensors now, any that have a habit of going bad or that would be a good idea to refresh right now while everything is accessible?

I'm talking with Sebastian at specialty z as well, great guys to deal with thus far! Tying to find out what I should be doing to my heads if I decide to get into them, any suggestions NICO? I don't want to drop 4G into my heads if I don't have to but I would like to make them reliable and able to meet my hp range without issues.

My car is getting moved this weekend to its building site, a buddy's 2 story garage with a hoist, giggidy!!!

Cheers guys

[addicted4life]

Im also emailing Yury @ Wiring specialties bout my harness. Now can someone tell me what I should be getting here, I've read that guys with 90-93 get the later style harness for injector reasons. If I'm getting a set of IDs will that affect which I decide to buy? I already need to have it modified for map placement so I want to make sure I get the right one off the bat.

Edit: What about my driveshaft?

I'm not sure - it depends on what SZ says when my car is on the dyno.
