also, Level10 makes a 1000whp capable tranny.

the stage 3 short block handles up to 1000whp per their website.

i live in PA with strict vehicle emission laws. i have not had cats on my Z for 8 years without issue. not hard to "know a guy" who knows they aint there but doesnt care. especially when FI makes amazing products that dont throw a CEL.

i have solutions to any excuse you can give lol

Except I seem to recall seeing several reports that Level 10 parts/trans builds haven't been holding up. Otherwise,

better than nothing when it's the only option.

excuses or not you can believe what you want lol. what i said was what happened and what is. sure i am using excuses to not learn manual, but i like my auto so ima stick with it. ppl gona hate on that but whatever. im still happy with it lol. i will just upgrade the trans with a fully RJM built one or something down the road when the time comes.

im not going to move out just because of a car reason -.- that's dumb for my situation currently lol. i love california and i dont think ill ever move out of it.

you may have solutions but it doesn't mean they will be plausible and logical solutions for my living situation at the moment :P

yes im too lazy and dont want to learn manual, so what. boo hoo. lol.
yes california sucks in that it has terrible fires and laws that are terrible for people who like to modifiy their cars. oh well. at the time i didn't have anyone to help pass smog for me so i was taking the safe route, anything wrong with that? xD

i tried to make do with what i knew at the time. but of course nobody would understand that because they weren't me so that's understandable.

Also. The stage 3 handles up to 850 rwhp as per their website.
The stage 4 has a typo on it in which i asked kyle about and even told him and mentioned it to him and he was like it was a typo and he will fix it but it seems like he never fully fixed it.

The stage 4 still says "stage 3..." on it but the RWHP numbers are changed.
If you look at the actual stage 3 link it says it handles up to 850 RWHP and when you swap to stage 4 link it says 850 - 1000 rwhp. lol

and cuz i have a closed deck short block from RJM it is definitely able to handle 30+ psi which im never going to make use of but hey its good to know lol

California sucks because it's run by a bunch of liberal f'cks. Same reason for the homelessness. Where I live we're virtually smog free. Haven't had an earthquake affect my area in the 62 years I've been here. Our smog laws are the most strict in the nation but it's easy to get around that. Fires haven't affected my area at all. I can drive my car year round.

We don't have tornados, which probably kill more people in a year than in the history of earthquakes in California. 22% or 1 in 4.5 people live in poverty in Pittsburgh.

See, both of our states are shitholes but I can drive my car year round in my shithole lol.

I'm glad I don't pay your taxes.

So when are you moving to AZ?

Every state has their stuff, some are definitely worse than others. I will take our stupid over most the rest.

Sorry to change the subject real quick but...just wanted to share what we found last night so far regarding where the boost issue is coming from:

(1) Boost Gauge shows 10.7 PSI at around 5800 RPM then the boost drops afterward (This was without any type of air filter / turbo guard on the supercharger head unit), with 3.0" SC pulley swapped out with the 3.2", and the 9PSI pulley on the serpentine side. (.74 bar = ~10.7 PSI). This was also in 3rd gear.

So we concluded that because the boost still drops and has the same pattern as before when I had the air filter on, and just a 9psi pulley swap to where the PSI dropped at around the same time (5800 - 6000 RPM) and after those RPM numbers, the boost dropped, the air filter definitely was not the issue even though it was pretty busted looking and very dirty.

We put the air filter back on for now as that's all the time that was had for until mid-november. We will do a pressure test on the car next to see if there is any leaks that maybe we missed earlier this year.

After that, if there is no signs of pressure leaks anywhere, then we will open up the blower and see if maybe there is anything wrong with the impeller. If that checks out...then I don't know.

Anyone have any other ideas where else we can diagnose this boost issue?
Thanks!

You could take off the SC side belt, making the car NA, and use the old carb cleaner search. With the SC connected, the positive pressure generated by the SC will keep the carb cleaner out.

I popped off the charge pipe directly from the SC, connected the pressure test adapter that I got from Z1, and tested using my air compressor.

Most of my boost issue comes from the filter, which is why I made a thread dedicated to finding something more efficient. I do most likely have a few little leakers though, as my setup, per Topgunz, should be seeing 15-16 psi but peaks around 13. I will look for those soon, once I have my intake setup done enough haha.

Good luck!

Thanks!

Smoke test will show you where your air leaks are located. Any competent shop will have the equipment.

[cupcakez]

Great ideas guys, Thanks a lot! ^^ Appreciate them. Will see about doing those things the next time we have time to diagnose it again later this month!!

Quick update on my boost issue:

(1) I was talking to a few respectable people in the Z community about my issue and what they thought of it after explaining my situation to them.

My Situation:
- I forgot to mention to you guys that my OEM idler pulley (the one between the Crank pulley and the A/C? pulley?) is missing. It actually popped out of the engine while I was attempting a pull one night and was forever lost.

Why? Because the person who worked on the engine last and put that pulley in there screwed it up and tried to retap the threads but failed at it, causing my pulley to pop out of it's slot when I was doing a pull that night.

Solution?
We decided to find a different serpentine belt to wrap around the entire remaining pulleys to "compensate" for the missing OEM idler pulley. (See attached image of the blue circled pulley that popped out).

The car ran fine, but the boost was extremely low for what my set up was. I was making an average of 6 - 7 PSI after this solution was complete. And we had no idea why.

At first we thought maybe its the area that the car was driving in at the time? Nope , not that. At my area the PSI was around the same lol.

Fast forward 9 months later (today) and I'm talking to a few respected people regarding this issu. 3 people say it was belt slip, everyone else (5++) say it was boost leak.

I'm like uhh, okay maybe it's boost leak then if majority says~~

Then I forgot to mention to some of those people that I was missing an OEM idler pulley and I told them the same story I told you guys just now.

(See attached images for what they thought and what they think, and also for an image of the missing pulley that popped out).

Unfortunately I don't have an image of the way the engine is routed at the moment, but it is definitely causing belt slip on the serpentine side.

One of the guys in one of the screenshots explains why!

What do you guys think?
Thoughts? Comments?

In lieu of all of this, in 2 weeks, I am going to gather up the following items:
(1)- Front timing cover
(2)- Missing OEM Idler Pulley (+) Hardware
(3)- Upper Timing Cover Gasket (Left and Right)
(4)- Front Main Seal
(5)- RTV
(6)- K071040 Belt
(7)- K080220RPM belt
(8)- Brand new K&N Air Filter (Current one I have is busted somehow, and looks almost like a cup, lol)

Going to replace the timing cover for 2 reasons:
(1) Threads where OEM idler pulley is screwed up, which is originally why we could not replace an idler pulley at the time we replaced the new belt on there.

(2) There is a tiny oil leak on the front passenger side of the timing cover that needs to be addressed. =)

[JARblue]

You lost a pulley so you just left it off and routed the belt differently? Talk about MacGyvering it lol
