Critique my parts list...

That spectre 8161 wont fit. I already tried. You do know the A/A comes with a filter right? What is the reason for the 8161?

Actually I didn't. Does it fit right onto the blower?

Senna-F1

Doesn't a Stillen SC + A2A put you in the same ballpark as a Boosted Performance turbo kit that doesn't need to be "fixed" ?

TopgunZ

Yes sir, it does.

If that is the must have list on top of the list above then I may as well sell the Z and get a GTR lol

Honestly, that's always a concern on building a turbo z. The final out the door cost puts you in a used gtr or similar car. Not to mention boosting a z pretty much destroys the resale.

I'd almost be tempted to run the SC alone this summer and do the A/A over the following winter, but I know I wouldn't be happy 'settling' for the stock Stillen package. Most of these costs will be amortized over the winter since I can't drive it anyhow so shouldn't be so bad. Just trying to be judicious what I upgrade and when.

I didn't buy thit car to sell it so not really worried there, however what can be done can always be undone. I keep all my stock parts.

Your list is pretty much on par with whats the bare minimum needed, the 25 row oil cooler would probably be the minimum sufficent for street driving.

The OS Giken Diff is a lot of money and if your not racing I would say it's over kill. Not to mention it needs regular service. Finned Diff cover is not necessary for street driving either. I would recomend doing all the drivetrain mods I listed, are they required no, but your CSC will eventually fail if not your clutch with the extra torque. Also not required but with more power comes more speed much faster so brakes need more stopping power. Tires are very important as well because spinning your tires can be fun sometimes, but it isn't productive, and why did you spend all that money on power if you just spin it away.

ChaseZ

The OSG is only a couple hundred more than a Cusco or Quaife if you watch pricing carefully. Fluid changes are expected and I just consider that routine maintenance. Also, being as I have a Base the OSG should be pretty much a drop-in. Couple hundred bucks for top quality is well spent in my opinion.

The car will see more than just street driving, both road course and occasional 1320. I'm looking at limiting tire spin not inducing it. It gets you nowhere except back into your wallet for replacements. 325 MT ET Street S/S Drag Radials out back.

The CSC is an issue I haven't addressed yet as the car was brand new just this past spring - and am fully aware it will need to be. Haven't decided what clutch/flywheel I'll run but it wasn't directly relevant to the SC install so I left it off the list. Sidenote: I did add LSD and gears to the list because I'm curious of others' opinions on the 4.08 R&P coupled with FI.

Easy enough to upgrade the oil cooler if need be but this one I'll wait and see how it goes. We don't really get staggering items here even in the summer, but will put it on the track for final decision.

I'm dealing with a close but out of town wrecker on stock Nismo brakes they have on hand right now actually. Depends what they come back to me with. If it's a good deal then I'll go for it, but will need 19's to clear them as I don't think the 18's will - though I prefer to stick with 18's. Will see what happens there.

Guess the short of it is just trying to piece together a plan for this winter's teardown, certainly doesn't mean I'm going to stop there. It also doesn't mean I need to do everything all at once either. Need a realistic list for now and try to not do or include anything that will have to be swapped out or upgraded again later. FI isn't cheap and I don't want to do things twice. Already sold most of my bolt-ons to go this route and we all know how much of a hit you take on used parts.

ChaseZ

Oh, and I get bent over by the exchange rate every transaction too so that's not exactly in my favour right now.

At least the only real labor incurred will be the rear end. I turn my own wrenches but don't set gears.

2011 Nismo#91

18s will fit with sport (nismo) brakes, a number of people who track got with 18s for better selection of tires and savings with each set.

Road course and quater mile are going to make brakes and fuel starve fix more of a requirement then a nice to have.

With that I think you're good to go!

ChaseZ

Very good to know about the brake clearance. I hadn't looked it up but seemed reasonable that the giant-by-comparison calipers would need a larger wheel or offset.

Ironically, I've found there to be much LESS selection of 18" tires nowadays, at least in the larger sizes above 305. Pretty much anything is available in 19" though. I guess 19 is the new 18..

ChaseZ

Should I/Am I going to need a fuel pressure regulator?

Think I'll back down to 750 injectors. The 1000 was just in case I ever ran e85 but the closest pump is like 10 hours drive from here lol. Will plan on having a 103 race gas map however.

Jayhovah

I love my Gamma oil pan. No oil cooler, TT, and Florida summer heat and so far no oil temp problems. I do not track, though, so I can not speak to the performance in that setting. Also changing the oil filter is more of a pain.. planning to relocate mine.

What are your power goals again? If you are going to skip E85 and 1000cc injectors... you can probably also skip the regulator, fuel return, Walbro 485 pump/accessories as well. Just retrofit the stock assembly with an Aeromotive 340 to go with your 750cc injectors and factory pressure regulator/fuel system. This would save a huge chunk.

FYI - I am only running 600cc injectors and a Walbro 255 in my otherwise-stock fuel system and have not had issues though I do feel it is a little small. If I had to do it over again I would do what I suggested above. This all depends on goals of course. I am in the mid 500's and do not have plans of increasing.

Thanks!

I would recommend you start installing anything you can right away to save time later... for instance, go ahead and install/wire your gauges and route the sensor wiring to the engine compartment.. That will save you at least half a day when you are like THIS CLOSE to driving it for the first time =)

Also anything you can complete in stages and will help, especially if you have parts ahead of time. For instance, install the whole fuel system and ask Seb to provide you a stock Map scaled for the bigger injectors... That way you can check-out that portion of the build and troubleshoot it without having changed a bunch of other things (if necessary)... and it will save you a day or more when you get the parts for the rest of the install.

Looking forward to your build!!
