Check my build..am I an idiot or pretty close?

After reading and then reading some more, I think I am getting the jist of this crazy thing called turbocharging. I got 2 books that have helped alot both SA Design; How to Supercharge and Turbocharge GM LS Series and Turbo: Real World High Performance and of course this forum, theturboforums and ls1truck.
Vehicle: 85 Chevy Full Size truck 3800lbs(maybe a little lighter when I swap some stuff around)
Trans: built th400
Rear: Braced 9" w/Strange Center, Detroit locker, 35 Spline Moser and 3.50 gears
Usage: 85% street 15% strip(1-2 trips to the strip a month) 28" tall tire(DR for strip) will keep it under 6800 rpm. I want it to be reliable so I am not looking for 100% max effort. I would like to see between 6-800 rwhp and be able to run in the low 11s/high 10s
Ok here is my parts list for my turbo build:
6.0l Iron Block 4.030" bore
AES 390" Stroker kit 3.825" stroke, 6.125" rods, 4.030" CP piston -13cc, roughly 9.2:1cr
Pat G spe'd cam
317 heads(unported will upgrade to AFR later on)
Edelbrock Vic Jr w/6061.com elbow 92mm TB
I will be using the truck manifolds to build the turbo system.
Turbonetics tc78 turbo
TIAL 60mm Wastegate
TIAL BOV size?
I am thinking 2.5" hot side tubing and 3" cold side(too big?)
I will run it through an intercooler(I will have to measure the location to find out what size I can go with) Will I need meth injection too?
For the fuel system I will already have a fuel cell and a walbro 255 pump(or should I just go ahead and drop the coin on the A1000 now) The motor will be run N/A until I gather all the parts.
I want to run 8-10lbs on the street and then turn it up to 15lbs on the strip. Can this be done with the stock computer? Would I have to tune it to the higher boost setting or is there something I can do to switch between race and street tune?(don't know tuning yet) I am open to all suggestions on this build. the only thing that will be set in stone is the shortblock, everything else is up for suggestions.

So am I an idiot or does it sound like a good plan?

Injection spray will probably be needed for high boost.
A larger pump than the 255 will be needed, not necessarily an a1000, but an a1000 isn't too big. Don't skimp on the fuel system.
-You'll need about a 75lb inj.
Stock computer will be fine.
You can probably get away with low boost and the intercooler, then high boost activate the meth kit.

2.5" hotside is just fine. 3" isn't too big and not too small.

Thanks for the advice.
Is there another brand pump that is good?
I am thinking -8an for the feed and -6 for the return for fuel, will already have a 20 gal fuel cell.

i didn't know you had a cell, i skipped that.

I would do the a1000 and only do it once, or a similar pump. I personally have never had an issue with them.
If you're gonna do 60lb'ers, you might as well do the low imp inj and do them once as well.

-8 will be plenty for the feed, go for it!
-6 is fine for the return.

Don't forget aeromotive filters before and after the pump.

What filter size(micron) should I use before the tank and then after? Any specific brand injectors?

May I ask why the 75lb inj?

I know is better to be safe than sorry, but at 700-800HP 60lbs inj are still at 70% inj duty cycle @ 8 psi with bigger turbos.

Will you want to keep it at or under 50% IDC?

Most do 100m before and 10micron after.

If i'm doing a build that requires 60lb injectors, I skip them and go for the low imp 75lb'ers.
Much better injector!!

but low Imp would required additional parts for the OEM PCM to handle them or not?

si, package comes with 8inj and a driver.

you can keep your driver...I wanna drive my own truck !!!

what about 95 High Imp Inj......would those make the same job at a lower price?

Question regarding the MAF, should I use a stock MAF or upgrade to a larger one? Where does the MAF go? Between turbo and TB, before or after the BOV?

Maybe you should consult a tuner !

Speed density Tune is a better option for the 15 psi you wanna achieve.

Seen Truck cars on 6-9 psi on MAF.

above 11lbs using a maf isn't the best idea its been done however it becomes increasingly ineffective.

I am posting these questions here bc I know there are tuners here because I am currently deployed to Afghanistan and these forums are my life blood. I would at least like to go to a tuner when I get back with some knowledge of what is going on.

if at home you are near S.A. Tx, your best bet is Allen Nelson for tuning.

IMHO I'll go SD tune (speed density)

btw, thanks to you and all the great man and woman risking their lives everyday for the greatest gifts of all.....freedom

I am originally from TX closer to the Houston Area, but currently reside in NC. There is a reputable shop close to me that has been recommended, but I really want to learn more of this myself and I wasn't aware that a SD tune would be better sutied for my needs. The books that I have are very vague when it comes to tuning so these forums are my life blood.

It's people like you that keep me in(no homo), thanks for your support.

Ok so I read up a little on the SD tune. From what I am gathering I need a 2 or 3 bar MAP sensor and a different IAT(intake air tempature correct?) sensor. I can attach a cone style filter straight to the TB while I am N/A. Where do I put the IAT? Does anyone have a part number for the IAT? The motor I bought didn't come with the MAF so I might as well go ahead and get a SD tune now(by now I mean when I get back and get the motor swapped). Should I go to a shop to get the SD Tune or can it be done by mail?

It can be done by mail if you have a way to log. It'd be hell though.

'02 camaro iat and grommet.
no mail order sd tunes.

edited: your post beat mine, just by seconds.

ya, only if you have hptuners or other, can it be done by mail order.
we tuned a gto twin turbo 2bar, sd, made over 600hp and runs low 10's in the 1/4 mile, stock engine, he's from Puerto Rico., so it can be done.

Thanks for mentioning my long distance SD tune 11 sec 1/4 mile silverado !!!! (Fag)

I used Blazer IAT AC213243. It must be installed before the TB (throttle body) so maybe a tube and then the air filter might be a good idea !

2bar map sensor I have is GM 12580698

For email tuning you'll need a software (we most use HPtuners around here) $400-$600

oh ya, and with the help from a very special customer, we were able to tune his turbocharged 408 :)

by "special" you mean retarded?

Get a life dude !!!

2Boosted,
My truck will be your trucks older brother. Flat Black with black wheels as well.
I changed my mind on turbo selection, I am going with a Borg-Warner ST80(83mm Turbine/80mm Compressor) This will allow me some room to grow.
Thanks for the help guys!!

nicer turbo.....

I was gonna suggest something bigger that what you originally post.

Then our trucks are sons of the mighty Lambodoornomo Truck.....check his garage...

My truck is based on him....first dude I saw with the Flat black theme that looks awesome ! (Perfect balance of nice and scary)

Did I mentioned I'm gonna do my truck like that? heheheh

no way.....FT? or the Caddy?

G's truck nice? The scary I believe, but nice? :lol:

I really like it dude....is like taken out of my fav movie MAD-MAX

Here is mine right now:
http://www.67-72chevytrucks.com/vboa...ictureid=12725
I will drop it some more and put some taller tires on the rear. I will have to save for awhile before I can afford the wheels I want:
http://www.67-72chevytrucks.com/vboa...ictureid=12562

My wife and son won't "let" me paint it any other color.

You have a good build going on but don't be afraid of a larger turbo. With 390'ci an 88mm wouldn't be overkill.

What about instead of an elbow and traditional LS style TB, using a 4150 style TB with a blow thru hat on it? Anyone have experience with those?
