Future Turbo build........need advice
I need some experienced advice here. I am a long time nitrous guy wanting to go turbo.
I am starting to make plans for my turbo build next year. Would like to know the best way to do this with what size, brand, turbo or turbos? Flanges? Single or twin?..................etc. What intercooler setup? Injectors?
Here is the engine/tranny combo.
396 ci LT1, AFR 235 heads 70cc (flow 340cfm), Supervic single plane fully worked, will have Cola 3.875" forged crank, Oliver rods, JE custom dished pistons, Hell fire rings, 9.0:1 , Jesel shaft mount rockers, solid roller custom cam, power-glide w/t-brake, 9" with 3.55's, FAST XFI engine management, Aeromotive A1000 fuel pump, -10 feed/-6 return, sumped stock tank.........etc.
Goal is to make 1400+rwhp.
I am a newbie to forced induction and would like some experienced guys to chime in please.
What would you go with and why?
Thanks

Are you set on going with a LT1 block? If you do I would have the block sonic checked and try to keep the overbore as minimal as possible both for headgasket between the bores and wall thickness. For sure going to need splayed mains. I think Big Rick was running around that HP level and having trouble with the blocks. I've never ran a FI LT1 but I do remember the tops of the cyl walls mushrooming out with high compression.
You need to look into either running two A1000's or an A1200 (eliminator) pump as I don't believe you can get much more than 1000rwhp out of one even with -10 line.
Good luck.

Your biggest problem is going to be squeezing a big ole thumper in there between the radiator and the motor. You'll need to get creative if you go this route. It is easier to package twins in these cars.
As far as pumps go, a single MagnaFuel MP-4303 will supply the neccesary amount of fuel unless you intend to use corn.
If you do any class racing, check the rules before you decide on which way to go.

I have no real advice here but are you looking to run in a certain class where they might allow only a certain size turbo or just looking for a fun fast car. Maybe something to consider so you only have to build it once. Good luck either way!

This is what I have learned going through 3 turbo builds. Always go bigger than you expect you need - if you don't you will end up spending more later.
Your engine sounds good. You will not know until you try it. Rear end, tranny (as long as it is built for the 1400rwhp you want).
Go with the 106MM. Go with the MagaFuel 750 (the big sucker). I would seriously look at a different computer set up (either BIG Stuff or AEM). Go with a good boost controller (AMS1000). Twin blow off and twin waste gates. A2W intercooler.
Fuel: E98 - more hp - $2.00 a gal; C116 - $15.00 gal. If you are going to run locally E98 is the way to go.
Be prepared to spend more $$ than you expect.
Hold on for a run that nitrous hasn't given to you before.
