Just for clarification: I have had turbos for decades on my trucks. I did not mean to insinuate that turbos in general are unreliable blast furnaces. I meant that installed tt's on the LT4...even the LSA is largely on untested grounds (compared to stock or even modified blowers). I meant one venturing into tt's for their ZL1 (pushing the envelope over 1-1.2 k rwhp) should expect some quirks, maintenance and possible reliability issues, if for no other reason that no tt system on any ZL1 has been through the proving grounds as blown ZL1's (when compared miles to miles).

That said, a thoroughly engineered, deliberately installed tt LT4 could very well be low maintenance and reliable. I stand by the +$20k figure, as most folks here will not being doing the swap themselves, and, I imagine, most folks considering a tt for their LT4 are seeking 1k rwhp, if not more.

Again, thanks for the post: lots of great response, info and insight.

My apologies to you, and everyone else... No argument was intended... No excuse, but I've suffered three strokes, signaling the end of my "racing" days.... I can be a butt sometimes... I was speaking generally, while trying to cover information for the OP.... I quoted so many so I could look back and see what I wanted to comment on....

You are absolutely correct in the mile to mile comparison, and the lack of people that have pushed the limits.... and yes, to go 1K plus RWHP, you are looking easily at probably 20K + (without going into the short block) before its all said and done.... I have always heard and now know that we make a budget, then double that and add a bit more.... So many nickle and dime things pop up...

I have the twins, though it's not a ZL1, and several friends have the ZL1 with twins, though they are so far beyond a bolt on kit.... A pure bolt on kit will allow for a specific growth, most anything beyond that will cause a wallet to thin quickly....
