I was wondering if anyone knows how much a stock L61 could handle with a garrett 60trim turbo handle?
or am I better to let my turbo parts sit for another year till I build a helpful
also if any one has this answer it would ne helpful dose the ss cobalt head bolt up to the L61?
any info is helpful.
Chris...
everything you asked has been asked and answered here about 234234234234234 times. just use the search feature, and figure it out man.
Im no eco guy but what I have read in the 234234234234234 post is with a solid tune the stock block is good to 400 whp and Ive seen people with 20 psi on stock slugs, not sure about longevity. Id be weary of how much boost a stock head gasket can handle.

Where???
I do not think no one has made 400whp on a stock Eco.
I have tuned one to 314whp on a stock motor.
For a daily driver I would say 275whp to 290whp if it is a very good tune.
Regardless psi does not mean much.

let me reword this post is any one running this similar set up on low boost, I have known two ecotecs to blow on a similar set up but they were running 10lbs, one of witch is the guy i bough the turbo from and the other was a 58 trim that blew. Idk if its the state we live in (arizona) or if its the fact that they over did it. so I am asking for someone suggestion on my concern, not a for sure answer.
I under stand how much boost you push what turbo it is reflects alot on this fact and that's all that gets said in other post. This don't help one bit that just tells me throw it in and cross your fingers that you don't blow.
again I would like some ones suggestion is it worth the risk to try and build later or just build it before boost.
or is there any one on jbo that's running stock internals?
Chris. Lemme tell ya....
The build in Aarons cars was AMAZING. his tune was @!#$. Same with Jim. There is something to be lost with mail order tunes. no matter how many times you send it back, it will NEVER be right. The fact that only Vince can see and read the data logs. I am very weary of that. He didnt know the weather condition, or how anything else was.
There is a guy here in Arizona that pushed 350 out of his cavalier all day long. stock BLOCK with wiseco pistons and aftermarket rods, and a stock head except for valve springs i believe. The blcok should be good up to 400ish. its the parts that fail. from my understanding, rods will fail ata bout 275-300. Im no master though.
that's the exact answer I was looking for I felt like trifecta was iffy on their part and was the cause of the problems they had. but was never sure and all ways trusted Aarons judgement.
what would be your best guess on where to go for a tune sense your local?
sorry if im coming off pissy bad day panties are in a bunch I just want to get this done
only people i know are on on cobaltss.net. there is a guy named chris that tunes lsj's and l61's in cobalts all day....he will be doing my tune soon.
a stock Eco if tuned properly should handle 10 psi with no problem.
I think I remember hearing about the one guys setup and if it is who I think it is, well he is/was a tool.
Get a real tune and you should be good.

I said the stock block could handle it not that a stock eco could make it.
yeah with my 3 inch pulley and a NOT PROPER tune, i see 13-14 PSI on a good day, and the engine hasnt complained yet. and im at 120k miles.
Eco block is only good to 400hp???? Hmm.... you sure?

without being sleeved, yeah i think that is right? i could be wrong. but i am pretty sure i have read this somewhere before.
Straight from the build book..
"The ECOTEC’s outstanding feature to performance
enthusiasts is it’s impressive strength. GM Racing
dynamometer tests confirm that major horsepower gains
are possible with minimal modifications. For instance,
when building an ECOTEC engine to the 400 hp power
level, no modifications to the cylinder head, block, main
girdle or crankshaft are required."

The gen 4 block is only good till 400 without sleeves, You can push it but it will fail eventually. I think the zzp girdle with a gen 1 block is good till 800. The gen 2 is good to 600? I cant remember that one.

Its not the state we live in but rather the individuals who own the vehicles

well Aarons car was lidgit it was just the way he tuned that I was all ways iffy about and I all ways wanted to ask aaron and jim about it but who is gonna say that it was due to a crapy tune. I got really lucky to where chris knew them both and thought the same as I did
I just hope I can gain enough knowledge from you guys to where I don't have a problem that big!!!!
Aarons car was legit after he built it. before when it was stock motor, that was just stupid. The car was awesome. It too bad he got rid of it and never had it tuned properly.
So if someone was to want to get to the 400hp level or maybee a tad bit more what would need to be done...new sleeves?? Is that it..? Just asking because thats what Im aiming for, but would be very happy with 380ish or more..Just wasnt aware that the block had to be sleeved..Thanks
@ chip you could get away without sleeves this guy aaron me and chris are speaking of ran 519whp on 22lbs with 11 0 but if your putting that much into a motor why not sleeve it and be safe. I will eventually do it but that's 2-3 years from now!
and I fully agree with you on that I just wish I could have seen that car with a proper tune!!!
im probably going to make 400 in mine, stock block bored .020 over. But the supporting parts and the best tuner we can ever have will be in mine.
ill be using a stock block also and be pumping out 550ish but im using a Gen II block

I'll be blowing mine up again, with less than 400hp and most likely damage my darton sleeves like I did before.
Hey, after 4 motors. I'm being realistic. lol
