That's mean.

 

trim says nothing. tell us what wheels. my 62mm is technically a 54 trim. it ain't responsive at all down low.

 

This.

If the exhaust A/R is a .82 or something you dont have to switch the whole turbo, just the housing to drop spool a bit. Frame size, Journal or BB turbo?

 

lol my bad its a .70/.63 the turbo is nothing special just an ebay one. The one I'm goin to has a garret center cartridge and should hopefully give me more pep. THe size on it now would be ok for maybe a built head. I just want an earlier spool for my current set up.

 

thats the exact same size a/r's on the turbo that was on my car before the build. spool was awesome. stu took the car to 12.6@114 on ~330whp and a 2.1 60'

 

those are decent A/Rs, you say you are going to a Garrett CHRA, which one? is it BB or still journal? What size wheels are inside your turbo? When are you currently hitting full boost?

I will be install my zzp swap tomorrow and throughout the weekend. I was told to watch out about the 2.4 throttle body harness, has anybody ran into an issue with the harness they send out?

 

booooo its been a while

damn i miss my lsj

 

it should be a journal bearing and currently I'm hitting full spool at 4100-4200 rpms. I'd like to see it closer to 3500rpm.

 

then something is wrong. a .63 a/r is not going to hit full spool at 4100-4200. and even if that is when its at full spool, that would be about 24-26psi. my 70a/r hits 31.5 at 4,400ish

 

do all of the ZZP kits use the 2.4TB or is it an option?

something is amiss if you are hitting full spool that late. take your housings off and make sure everything is as it should be. seems to me like you may have a bent fin or the edges have been rubbed off of your wheels.

l8r,
PD

 

i believe they all come with it. difference is out lsj one is 8 pin and the 2.4 in 6 pin. was seeing if anyone had issues with the harness they deliverer with the package

 

dunno maybe something is amiss. I could hopefully have the guy Im goin to take a look. Maybe I messed something up with my waistgate when I replaced the spring in it.

 

How are you dropping your spool down, out of curiosity?

I've got some tips and trick to use, as well. You might already be using them though.

How are you ramping your AFR during spool up and what's your timing map like?

Adjusting both of those gave me HUGE improvements in response, out of boost torque, MPG, etc.

Nah. Plenty of turbo LSJ's have made it into the mid-upper 400whp range. Its all in the tune though.

Well that's rude.

No reason for a ban, though.

Ding.

Its all in the set-up and the tune. A lot of factors add in. If its a journal bearing turbo, 4100-4200 really isn't all that far off, depending on wheel sizes. He did say its an ebay turbo.

Doubt it. I'm betting that if its not in the set-up (leak, improper pipe sizing, etc)... its in the tune. From the base tune ZZP gave me for my Return System... to the tune I created... there was a spool difference of about 600rpm.

 

Okay, so, every now and again, I get oil coming out from the exhaust (blue smoke). This is what seems to be the two consistent conditions:

(1) The car is ran at operating temps (irregardless of how long), turned off, and then re-started USUALLY when the car is still warm (upwards of 100*). And;

(2) Oil life is low, typically 4-5 months or less than 80% life on the HUD.

It's not a terrible amount of oil where I'm losing a quart or so like before (see previous thread I posted). After I drive the car for less than a minute, it'll stop smoking. If I idle it for a while, like for five minutes or so, it won't do it. Or, if I let it sit and cool down, it won't do it either. I have the air compressor filter on the pcv port to my intake, and a breather on the oil cap (Rob, don't say anything, I know it's a patch). Anyone wanna chime in what it could be?

 

internal or external? what kind of spring did you replace it with? a leak there would definitely slow down your spool

Im using a quick spool valve to manually reduce the AR of my exhaust side lolz. Chris and I have made quite a few changes to the tune to help spool time. I can get him to PM you with sum of the things that we have been doing. I need to get him some better logs to work with and Im sure spool time will begin to decrease drastically. Ive been a very lazy ****** lately lolz

I typically doubt it as well but I have seen people damage the fins on the compressor or turbine and it slows spool down or makes spool impossible. A large leak on the hot side could very well be an answer here. Maybe he can chime in and tell us that prior to the wastegate work that his car spooled more quickly.

I was unaware, Im still running my LSJ TB, Im wondering if it fits differently than the LSJ to the Saab manifold. Would help me with another build that I am working on

are you cooling the turbo down properly before turning the car off and allowing an ample start up time. Honestly, Ive never owned a turbo car that didnt puff out a lil blue smoke.

why werent you at the bash? I was the only turbo swapped LSJ there.

l8r,
PD

 

As to your first inquiry, yes I give it ample time to warm up. Probably not as much as I would like b/c my afr's at cold start are pretty harsh right now due to a vac leak that I haven't had time to fix properly. But I do let it warm up to about 100* before I start driving it, and I don't go into boost until it's about 140+. Like I said, it's not a terrible amount of smoke which is why I'm not like "zomg my car is gonna die!" I've seen my bro's old speed6 puff a bit, but not as much as mine. In terms of cool down, I already explained that it only happens when I don't let it cool down enough.


As per your second inquiry, I have my reasons for not going (not gonna get into it here). Nothing to do with Centexx. Love the Austin boys, and I got much love for Scott (no homo).

 

chimin in lol. The turbo isn't damaged because it is relatively new even for an ebay. I bought it new to replace an older one so it has less then a few hundred miles. It is externally gated with a tial unit cus the one before was not workin properly at all. I only thought maybe it was the gate just cus I struggled to get it back together cus of the tension from the one bar spring and I had no tools to hold it together but my own power which was horrible to say the least.

I haven't mentioned I do have a 3inch exhaust size charge pipe and a gigantic intercooler, but Im not sure how much that may effect spool time tbo.

 

its kool if you dont want to get in to the details here I understand. Hell if I lived in Houston, I wouldve been at the Texas Mile and not the bash. Nothing against all of the other GMs in the state, but it is the Texas Mile lol.

define gigantic? but yes your IC piping is way oversized, what is your pipe routing, shorter pipes faster spool. Drop down to 2.5" piping that will decrease spool time.

All the guy that swapped with the ZZP kit i have some questions. What did you use for the throttle body gasket i didn't receive one?

Also do we use these two things in the pictures i'm posting and if we do where do they hook up at thanks, finishing this tomorrow so i'd like to know

 

You just use silicone to make the gasket. First thing next to the evap solenoid is the supercharger boost control. You can remove that because it is not needed. The second thing is the brake booster which the saab manifold has a hook up for.

 

You def have to hook up the second one or stopping would be a huge problem. The first can be removed as Blazin has already stated.

Ah, okay. Good thinking. I've seen the Turbos that have those built in, pretty nifty.

As far as AFR and Timing... the more the merrier. For the AFR, I'd ramp it down from 14.7. A lot of people seem to just flatline their AFR... so as soon as they mash the gas, it goes to 11.5 or whatever. That's safe... but its not the best for spooling fast. I'd start at 14.7 and slowly work my way down to 12.0 by the time it hit full boost. Cut out a decent chunk of spool time like that. It takes some calculating and some time... even more so once you have to adjust it because of what you gain. With the timing... basically the same concept. I ran a lot of timing throughout my map, until the turbo was spooled. I haven't looked at it in a while, but I think that around 5psi or so, it was still around 32* of timing. I ramped it down, as well. That gave a huge improvement, not only in spool. time... but also in how ballsy the car was out of boost.

That charge piping will do it. I run 2.5" I/C piping all around (shortest route possible, as well) with an 8" long section of 3" piping for the MAF.

 

large as in 1inch past the bottom lip and a few inches above the crash bar. thick enough to have been held in place by being wedged in between the crash bar and the A/C radiator thing which it bent to a slight curve just to get in there.

 

Dude I feel your pain, I'm almost done. All I have left to do is downpipe, waste gate, one ic pipe, and then put the bumper and headlights on. Been working on it for two full days. I'm exhausted. Yea just use the grey sealant for the oil pan for the tb gasket
