Nice. :tup:

I think it could also include some tips for how to tighten some of the fittings that are difficult to get to or what tools can be used in certain instances. I also found that there were a few holes in the manual that were easily overcome but do cause some confusion.

These are fairly minor but thats what I can remember thinking about when I was doing the install.

So I guess, going over the instructions a million times and jotting down notes, questions, possible problems, items needed, is a must, or would at least make life a little easier (I normally do this anyways). Of course the DIY's you guys have made help out a lot! :tup:

very nice! subbed for future reference and updates

Hope the car is faster than this thread is moving. ;)

Looks great Nick! I might be in NY soon, maybe I stop by to see it!

yeah yeah, I haven't been able to touch the car since wednesday and I'm leaving for vegas for the weekend, no progress until next tuesday :shakes head:

What a slacker ;)

gabe3d 04-13-2012 12:58 PM

Great stuff, car looks amazing.

pady999 04-21-2012 10:56 PM

wow nice garage set up. This looks fairly easy to do just seems time consuming.

esfourteen 04-29-2012 08:26 PM

back with a massive update after a bit of a hiatus! Check the first page for new pictures and a start up video.

The car is now running, it started up immediately with no issues. I had to fix 3 or 4 coolant leaks, the passenger side banjo fitting for the coolant feed kept leaking, I finally got it to stop but nearly stripped the damn thing, what a bitch that was.

Remaining TODO:

Swap differentials
Install catback
Install gauges

GaleForce 04-29-2012 09:56 PM

Awesome! Good job :tup:

roplusbee 04-29-2012 10:00 PM

Awesome! Congratulations.............

roplusbee 04-29-2012 10:04 PM

Now I just need to update my build status. Man, I hate Afghanistan!

Ron 04-29-2012 11:48 PM

Sweet! Congrats Nick!

DIGItonium 04-30-2012 12:13 AM

Wow it sounds so good without the exhaust lol. So that's how you can hear the turbos spool?

esfourteen 04-30-2012 07:41 AM

thanks guys! the car sounds pretty beastly with no exhaust, I could imagine someone running some straight pipes on a TT. You can hear the turbos spool quite easily like this, but you can also actually hear a bit of compressor surge at the end of the video. The BOV's closed before the air had fully escaped, I think they might need a weaker inner spring, I'm going to call Sam today and find out what springs they are using.

Ron and Digi have you heard any compressor surge with your kits?

I have been driving mine with no exhaust for a little while as I wait for my new one to get here and I don't see a point in putting my stock one back on. It sure is loud but it's got such a unique sound. It's fun for a bit but gets old fast. I should have my new one this week.

I've only heard that sound when I let off the gas at very low boost. ~ 2psi. I always figured it was just the BOV's chattering a bit.

Ron 04-30-2012 08:05 AM

Yeap. I get some fluttering at very low boost too.

Yeah it's really not good for the turbos, at least yours have anti-surge built in :tup:

SPOHN 04-30-2012 08:34 AM

I know sometimes the BOV springs seem to be stiffer when new. But in due time they soften up once broken in. That's what happen on my FI 350Z.

Great install and props to you. The only thing I feel funny about is how close the oil cooler lines are to the engine mount?

Thanks! The oil cooler lines are close but they do not touch, I am quite paranoid about stuff like this. I've had the oil cooler lines in the same orientation for over a year already, I was just re-routing the path of the lines to clear IC piping.

I'm still iffy when I hear it. I'm super anal about my car and it working properly lol.

About the turbos spooling, I can hear mine below 3k already spooling and under boost they sound awesome! Even better now that I got the recircs on.

Did they line up or did you have to have them remade?

Ron 04-30-2012 11:44 AM

Passenger side had to be cut and rewelded. Driver side went in after loosening all other pipes.

Just read the shab a ga bang and I'm loving it. Congrats bro

DIGItonium 04-30-2012 12:19 PM

The first few months of FI you'll hear this "surge" quite a bit, but only at very low boost. It has diminished a bit since then. I talked to Sam about it as well, and he told me it's normal.

Wait until you kick up the boost... then the BOVs will really start to make some noise. It's music to my ears haha.

BTW, I still have the Southbend clutch, but Joe provided me with a full face ceramic disk to replace the DXD street disk. The new HD-CSC has a different bearing on it as well. After finally giving it a proper bleed, everything feels great now.

nice, I had my marcel adjusted in the soutbend so hopefully I can get this working properly when I need to re-install. Do you have any pics of the new HD-CSC, I haven't heard of this? I guess I have the old version.

I disagree that compressor surge is "normal" however, at very low boost I'm sure its not as harmful, but it should not be happening. Thats the point of the BOV, different springs can be used in this particular model and I wonder if they just could not find a spring that worked well. I don't know if the throttle plates and VVEL play any role in this issue either.

chuckd05 05-01-2012 01:47 AM

Just now finally heard the startup video... I am so mad I haven't made it down there yet... Sounds and looks NASTY... love it...

Hats off to you nick... we gave up on a diff swap yet you tackled this like a Pro... or maybe better? RTV usage seems to be in check unlike some other people we know, haha....

Can't wait to see her in motion...

Also, any reason why GTM goes with turbo smart BOV instead of a tried and proven Tial ? The BOV's you have look exactly like Tials but I guess they are not as Turbosmart is on them, unless that is a Tial ?!? I would def swap the spring though.. I know Tial has springs depending on your vacuum pressure and you get the spring according to that... Tial swaps them for free or sells them for a few bucks... Def with you on surge not being something I would accept as normal..

esfourteen 05-01-2012 08:21 AM

It's all good Chuck you will see it soon, I'll be down there every night this week wrapping it up, should be able to take it home this weekend. I had a feeling you would appreciate my RTV style after what we've seen, the trick is not to use an entire tube on one gasket lol

That diff swap was just a time issue since we couldn't leave our cars that night. I actually just pulled off the 4.08 diff last night and im installing the 3.5/quaife tonight :tup:

As for the turbosmart, I'm not sure the reason for switching, they are about the same price, I do know that these are the new model though and are a bit more compact, very good BOV's. I will give it some time for the spring to soften, if it continues to do it I'll just get some different springs from turbosmart.

My kit came with the Tial 50mm. I also have the surge at low boost. I heard good things about the Synchronic BOV taking care of low pressure surge.

Are you using the DXD organic or ceramic disk? I learned it the hard way when I called Joe after barely making it out of the hole at the strip. Clutch disk welded with the flywheel at launch. Joe says the disk can handle power, but not heat so it's not made for dragging. I have the full face ceramic. Joe didn't think it was good for daily driving, but this new disk is awesome! Engagements are smooth, and it doesn't slip. He says it handles over 700 lb-ft. O_O

I don't have pictures on hand, but the bearing has a larger flat surface so it seems to engage so much better than before. I don't have the nasty judder feeling either.

Just make sure to crack the hard line to the master to bleed bubbles first, close it up, then crack the CSC bleeder. I'd pump the pedal nearly 40 times, held down hard, crack the bleeder (feel pedal sinking further), close, lift pedal and repeat. Adjust stroke such that you have rougly 0.5" of play. Resistance should be firm and not as mushy. If you did it right, pedal feeling should be the same the next morning and after warming up.

Goodness this car is so much fun to drive now. There's no more gear notchiness either. :)

Yea it's organic.

I need to start looking into clutches I have my heart set on a couple of turbo kits, but haven't even thought of a clutch and flywheel
