I just wanted opinions on which you would think would be most beneficial to have first on a turbo'd lsj. I might have some store credit and the only thing I would need that the vendor could provide would be one of those options. If they can come up with a waste gate I'd still like to know for future refference. Looking for both engine longevity and performance in mind with the meth/return style question

 

I would go with return style cause most people ditch meth in the long run. If going meth you might as well skip it and go to e85.

 

bump

 

return style fuel system.

 

your going to get more gain from boost rather than timing advance. turn up the boost

 

lol I can't yet...i need a new wastegate asap the one I have is a pos delta style. I thought my injectors were the issue so I bought some only to find out I don't need them. I'm hoping the vendor I bought the injectors from might supply turbo parts very soon. also I need an intake tube made to come off the turbo and my dump pipe fixed cus its is dumping hot air right into the turbo just killed my numbers

 

how do you know the wastegate is the problem?

 

I went to get tuned this past weekend at a place in tampa from a guy named Jeremy Formato. I wasn't building or holding boost properly at all. the prob with the dump pipe getting cut and dumping all that hot air right back in to the turbo is huge too.

 

jeremy formato is big in the LS world. didn't know he tuned cobalts too.

 

yes thats what I heard so I was very happy to take his opinions lol. it was by chance I found him...I searched online and clicked and he was the first referrence I landed on.

 

You would be suprized how many people ditch E85 for meth too. Its a proven fact methanol makes more power than ethanol. why do you think top alcohol runs methanol? But both do have there cons. Methanol injection you got an extra tank to keep filled up. E85 got to memorized where you can get gas from. Your going to spend about the same amount of money to go either route.

 

Why is this even a legit question? Return fuel 10000000%
