hey i would like everyones advice on the best way and best parts to use to build an engine using a lt1 block that will be able to withstand a twin turbo set up.

 

speak to an engine builder exp. in LT1's and forced induction. IMO

But stronger shortblocks lead to lesser headaches.....

 

Low compression, all forged...If you have the money for the best (and still wanted to do it yourself) I think the callies racemaster crank, oliver billet rods, and some JE pistons are about the best you can get. Just my opinion.

 

Let an engine builder do it..

 

I am not clear on your question. Do you mean specs/parts selection or a literal "how-to"? The LT1 is, in most repects a typical SBC. You shoould be able to "build" an LT1 if you build a SBC. for some LT1 specific info., there is some good basic info on-line at http://www.automotiverebuilder.com/ar/ar99928.htm For more detail, consult this book: How to Rebuild Small-Block Chevy Lt-1/Lt-4 Engines: Step-By-Step Rebuild to Factory Specifications, Covers 1992-1997 Gm Cars and Trucks (Paperback)
by Mike Mavrigian

Somehow though, from the general nature of your question, I am thinking the advice to consult an engine builder is reasonable. If you want a suggestion who is not an advertiser, you can PM or email me. Otherwise, look at the folks who advertise here or someone in your area who is trusted.

I must agree with Rich, I have that LT1 how to book for engines and its really good, especially since it applies to what I work with.

A few months ago I was looking for a good n2o book and I saw his comment on Amazon about not getting a specific book on Nitrous, it was a SA design book, and I was like, maybe it could help. Welp, it didnt, it was a honest waste of money.

Basically gave a broad overview on the subject but nothing to do with wet systems and their "tests" with cars were really shallow in depth.

 

David Vizard has a decent book on nitrous. It's dated though and is about carb setups. Still, a lot of the principles do apply to EFI.

I like to build my engines using legos. Typically works best to use the rectangle peices as they add a lot of strength vs. the regular square peices which will fall apart easier.

 

I see by your sig that you like to stack things (like Legos).

How about observing the 5 line sig limit set by the website admins?

 

i want a specs/parts selection.

 

how about you build a ***** and go **** yourself.

 

ROFL I just laughed so damn hard. Thanks for that darthrug

 

your welcome. now anyone who would actually care to give some constructive advice please do.

 

"Twin turbo" implies high boost, which means you are going to need a low CR and some stout parts. As far as the rotating assy., while there are many good choices I can tell you my preferences, what I know works from personal experience.

1 Crank: Callies "Dragonslayer" or Lunati "Sledgehammer". The latter is preferred with the 5.7 rod I recommend as the counterweights are designed for rods that short.
2. Rods: Lunati "Pro Mod" 5.7"
3. Pistons: JE "blower" pistons.
4. Rings: Speed-Pro "Hellfire".

The block will need to be machined for 4-bolt main caps. Use the Clevite "H" series bearings.
