Check EPP there is T.A in customer section 900rwhp or close with same heads but not sure about the turbo size.

Hope it helped.

I dont think you can get a "gt45" in ball bearing form. Is this one found on ebay? If so, its probably jus a standard bearing. Also, a GT45 is a 68mm turbo... way too small for a 408ci... unless you are using 2 of them.

Depends on the manufacture. The MP GT45 is a 68mm journal bearing unit. The Garrett GT45 is a dual ball bearing and we offer it in several different compressor options.

No a GT45 has a 83mm hot side the compressor side is a 68mm.

Definately the wrong turbo for a 408ci.

PT88 is a better turbo for an LS1 monster, then the GT45 from Garrett. Its 12 blade turbine wheel doesn't flow as well as the TV style wheel, but it does spool fairly quick with the DBB and 83mm compressor wheel. Its a T4 as well, which does make it nice.
