For Jayhovah and TBatt, done and in progress haha. I bought the 34 row F.I. oil cooler from a member here and will be installing today while the car is taken apart for my wonderful injector snafu.

Uh... what spacers? I just installed these same Injectors a few weeks back and don't remember anything specific about spacers. Course it's possible I just installed them without taking note. Only thing I really recall is the two seals per injector, top and bottom.

Approved.

The Real, Evil Gremlin...
 

So... I received my oil cooler today and pulled the intercooler off to install it. In the meantime, I decided that I might as well change out the SC oil, just to see how it looks given my sound. The drain line was clogged. Not too big a deal, cleared it and holding on to the initial oil that came out of it to figure out what clogged it (not a lot of optomistic options...).

Once the oil drained, I re-installed the plug and put one bottle of SC oil into the unit. I begin to assemble my oil cooler bracket and I'm ready to mount it to the car. I look and see some SC oil, well away from where it should be, so I look for the leak. THERE IS OIL DRIPPING FROM THE CHARGE PIPE TO THE INTERCOOLER!..........

I'm kind of at a loss for words at the moment... Also in a little bit of shock and denial... Calling Vortech literally right now in hopes they can at least get me a quick turnaround on the unit...

Vortech thinks probably bearing/seal failure. Surprise surprise...

And this kids is how we learn very valuable lessons.

Wish me luck!!

The pictures...

No bueno, amigo!

Hope its a quick/cheap fix!

There are some 3/16"ish spacers where the injectors meet the engine to ensure the injectors remain firmly in the rail and in the engine. If you do not install them, fuel pressure can force the injector further than desired into the block and lead to the top developing a gap between the injector and the rail. After a little cooldown, I felt the inboard side of the injector at the rail and I could feel the o-ring. Also, significant spray from between the rail and the injector upon priming the fuel pump by turning the ignition "ON"

If you look at the picture, the spacer is actually on the injector ("top" or engine side of the injector) at this point. How they got removed is beyond me...

Awe hell!! So this is the unit the guy said had only 12K on it and right before he sold it to you he "rebuilt" it? Did that noise ever go away?

This is... and yes... and no...

The SC is off the car, in the box and ready to ship 45 minutes after getting off the phone with Vortech haha. I'm sad to say I'm getting good at this lol. Once the get back to me on the rebuild, I'll authorize it so that I can get it back ASAP. I think I'll probably go with the 78k bearings as well while it's there to save myself time in the future. Don't get me wrong, I have zero intention of overspinning the SC at this point in engine and tranny condition (stock).

Hopefully it'll come back and purr like a kitten :)

Gotta keep lookin' on the bright side!!

If I were you Id have them upgrade to the SI trim no doubt! Also, your motor can take anything that supercharger can throw at it. The tranny is your limiting factor but I would still say your safe at spinning it to produce 11psi. I was making 414wtq at 12.5 so at 11 you should be well under the 400 mark. Just make sure you use Seb as your tuner. With him behind the wheel of the tune I would spin it to 75k and make 450 all day.

The bright side is that fuel sprayed all over your hot manifolds and you didn't lose the build to an engine fire. =)

This is a small price to pay for that miracle :happydance:

It hurts reading this. Looking on the bright side and gaining experience is the best way to view it. I hope you get this sorted out soon man

Man, you've got me breaking into a sweat now, and I am just a desk jockey behind a keyboard. Only the brave! Good luck!

Checked mine, looks like they were on there so in the clear. Phew.

Supercharger is on the way back from Vortech and should be here Friday! Minor rebuild with the Si trim upgrade (thanks Topgunz for really twisting my arm on that one haha :icon17:) As soon as it gets back, I'll have it on and oiled and hopefully be able to take her out for a Friday night cruise :excited:

Long time coming!

Awesome..how much did the bearings and impeller upgrade run u?

Got the SC back a day early!!! Slapped it on, refilled all the fluids and turned'er over! That marbly sound seems to be coming back..... Which makes me wonder, how tight do you tension the small SC belt? Could radial pressure cause the imbalance leading to that sound? Just spitballing a little here. It is definitely quieter than the first time!

YES! Do not overtighten than a 70* twist. I had mine at about 90* because when i went to 45 you could hear the bearings being stressed. Your marbles.

I don't really understand this, I'm sorry. Is this 70 degrees turn on the tensioner? If so, where is your starting point (i.e. 70 degrees from the point you can no longer push up on it yourself?)?

In hindsight, this may have been what caused the very original and subsequent failure of the bearings. I refuse to repeat that mistake!!

At this point, I feel like backing it off until belt slippage occurs and then tightening from there might be my best bet.

Thanks!!

Edit: Any tool recommendations for tightening/loosening the tension pulley from the top with everything installed? I am going to run to Lowes for a 9/16 crowfoot today, but I was curious if you guys had any tools that worked really well from the top.

If you guys wouldn't mind taking a look at the last three videos and tell me what you think about SC belt tension/sound I'd appreciate it!

Put down 410whp/310wtq before they thought I ran lean and wouldn't pull it again... AFRs solid, no higher than 12.03, so I think they might have had an issue with the probe they were using for AFRs. I was hoping for a little higher, but I got the WOT data for Seb at SpecialtyZ to iron out the top end and maybe find a few more horses. It's looking like time to pick up the 9lb pulley

No way. Your tuner is off. There is zero chance of running lean at 410whp with that fuel setup. I was running without a rfs and made 533whp on E85! Which takes 30% more fuel!

Plus those mods should have you deep into the 400s, not just barely over. Something is wrong.

This is sounding like my build O.o

I sent the data from my 2 dyno runs to Sebastian, so I anticipate good things!

Woo from the forum here lives out by me and said he was running ~447 on a similar setup without fuel mods (other than bigger injectors, so I was hoping for that at least!
EDIT: I believe he has the F.I. exhaust which is a little bigger than my Borla w/ test pipes. This may contribute to lower numbers.

Dude at the dyno day also said he let off at the end because he thought it was running lean based on their probe. Again, triple checking the data, No AFR's on either bank above 12.5 until the gas was let off and my hp/tq graphs looked almost identical throughout the ROM range despite me allegedly running lean 2.5k RPM sooner on the second run. It was a dyno day even and not a tuning session, so I can understand the conservative approach to not running the car again given the data they could see.

I didn't open the data files until I got home to scour them for any issues. I'm not confident in my ability to tune a car, but I am confident in my ability to find and diagnose a lean condition based on pedal position, AFRs, MAF voltage, injector cycles, etc., if it exists, and I didn't see it.

I'm looking forward to the next iteration of my tune and I can't say enough good things about Sebastian so far! Based on the 310wtq number though, I feel safe moving up to the 9 pounder, if I can find one these days that is haha!

Thank you guys for watching over me!! Hopefully more to come!

I'm putting together my stillen build. I've got an si supercharger, 9 lb serpentine pulley, a 2.87 sc pulley (will be installed if initial hp numbers aren't sufficient), a2a kit, tensioner pulley, s1.se kit, billet hat, walbro 450 with x1050 injectors. It'll be tuned for e85 and 91. I'll be flat bedding my car to Seb hopefully within a couple of weeks. I'll let you know what numbers I get.

Here are my before and after(ish) dyno sheets. I say after-ish because after sending my stuff to Sebastian, he noticed that I flashed tune rev 2 instead of rev 4, so I'm a moron who can't tell the difference between 2 and 4 and who dyno'd on an unfinished tune... Not his fault at all.

Before: K&N Typhoon Intakes, Z1 ported upper and lower intakes, Z1 test pipes, Borla exhaust, tuned w/ Uprev @ Z1.

After(ish): Stillen SC kit w/ Topgunz A2A conversion, TBatt idler pulley and Si Trim upgrade @ ~9 psi, ID1050x injectors, AMS lightweight pulley, F.I. 34-row oil cooler, CJM S1-SE Fuel Return System and billet tophat w/ Aeromotive Stealth 340 pump, Z1 ported lower intake manifold and test pipes, Borla exhaust, tuned(rev 2) w/ Ecutek by Sebastian @ SpecialtyZ

Once I'm able to get on the dyno again with the right tune revision, I'll post up again.

Looks like you must be on just the 8 psi pulley and 3.2/3.2 sc side pulleys. Im also guessing he didnt have much timing in the Rev2 map vs. Rev4.

Your all geared up for E85 also which would give you some great gains.

I bet you're itching to get back to the dyno, I definitely want to see your revised results. I got the rest of my a2a kit (thanks Aaron) on Saturday, my car would be in the shop this week for install but I decided to get my maf pipe powder coated. I get that back on Friday, hopefully my car goes in next week.

Update 3/13
 

Just a quick update on my car.

Installed 9lb pulley last night. The car feels significantly more responsive with it over the 8lb pulley. Next dyno day looks to be at the end of March, so I'm gonna do some datalogging with the 9 pounder to be ready this time. Numbers to follow...

To go on next week sometime: Stillen A/T oil cooler and Z1 power steering cooler. And maybe a Nismo spoiler :tup::tup:

Quite honestly, I'm a little scared of E85 right now haha. Once I get a real job (outta the Navy), I will pick up a built tranny. After that, I hope to be on one of those fancy YouTube videos or somethin' haha:excited::excited:

New Life!
 

Most of you have probably seen that I was T-boned in my Z about 8 months ago... Well, I can finally say that I am back on the road in a Z!!

I bought a 2011 Monterrey Blue 370 and transferred all of the parts over along with a couple more subtle changes.

Welcome back to Z world!

Next steps coming for my build (end of the month):

FI Long Tube Headers
Z1 poly motor mounts
New gallery gaskets with EPS hardware kit
New water pump and timing tensioner (convenient maintenance)
Prosport Evo Oil pressure meter (matches my boost and AFR meters)

Once this is all done, I hope to stabilize the tune (I feel like tuning is never "finished" haha) and get to a dyno mid-March! Then back to autocrossing and maybe a couple beginner track days!

Thanks for the advice and following!

Welp, I'm done with this phase of the car haha.

First of all, thank you to you all for advice and help over the last few years. Thank you to jlarson for allowing me to re-home his headers! Thank you and shoutout again to Fast Intentions for great customer service on a secondhand purchase of one of their products (Oil cooler and long tube headers). I hope to actually buy something from them here soon (tow bar, flexplate)!

Final mods on the car now are:
Vortech V3 Si Supercharger with Topgunz A2A
"Custom" supercharger intake
9 psi serpentine pulley
3.15-3.00 SC side pulleys
Z1 ported lower intake runners
FI long tube headers
Borla catback
ID 1050x injectors
CJM S1-SE fuel return system w/ billet tophat and Aeromotive 340lph pump
FI 34 row oil cooler
Stillen transmission oil cooler
Z1 power steering cooler
Brand new gallery gaskets with EPS hardware
AMS lightweight crank pulley (stock diameter)
Z1 poly mounts/bushings for motor, trans, diff

Initial test drive shows 14psi at 7k RPM, but tuning is in progress with Eugene (ByThaBay). Car vibrates a good bit more over stock haha.

Still have the oil pressure meter to add.

Next mods will be more aero/aesthetic. Looking to add a V1 Nismo bumper, Nismo V1 spoiler (or something else, not sure yet), aluminum undershroud, powdercoated wheels (not sure on color yet), 3.69 geared diff.

What did you end up with intake wise. You must have fixed something. Are those the stock pulleys?

I added 3" PVC to before and after the rectangular transition. A minor airflow obstruction, but it's the best I have right now and it seems to hold up. Playing with the idea an aluminum transition piece or something like that through the transition to completely prevent collapse. Right now, the tubing bends slightly inward through the transition.

I do not have stock pulleys. The 9psi pulley is the commonly added one, but my SC side pulleys are the high traction versions from Vortech. If they do indeed eat belts like I've been told, I may order the standard pulleys and swap them out since I still daily the Z.

Logs also showed that I was starting to lean out on top. Investigation yielded that my fuel pressure was 10 psi low, so I corrected that. Weather permitting, I am hoping to hit the tuning hard on Friday.

You went smaller on the jackshaft pulley, sc side?

I haven't seen any issues with vortech high traction pulleys eating belts. The 928 high traction pulley I had destroyed one of my belts but it was a sprayed on coating that was like 80 grit sandpaper.

I recommend the gates k080220rpm belt. I'm using smooth pulleys at almost 17 psi with no belt slip. With the standard k080220 belt I had crazy belt slip with smooth pulleys even at 13 psi.

3.2 jackshaft - 3.2 SC is the stock size

3.15 jackshaft - 3.00 SC is what I have now

The vortech belts don't seem that rough thankfully.

I have an order in for another K080220 belt since the keyway in one of the Vortech pulleys failed and ate the belt, so right now I have a standard? k080220 belt on that is near the end of it's life lol

Yeah, I know stock pulleys are 3.2/3.2. I was wondering why you went smaller (3.15) instead of larger on the jackshaft.

Have you tried the the rpm belt?
