How would you go?

Here is what I have now...eagle forged bottom 383 14.1, big cam on a 103, single plain with a 4150 TB 1500 CFM.

-So can I get an elbo or something for the TB?
-What turbo etc shoud I run brand/size etc.
-Someone sell everything in a kit and I can fab it up or what?
-What static comp should I look for? probly just order a custom set of pistons.
-Pretty much if you had what I have what would you do?

I know nothing about turbos, This is a drag only car and I'm tired of being the slowest one around......I want to see some 8's

Also I have 60# injectors DFI, I will most likely go to a 3.73 or less gear w 28" tire, and new trans/converter built for the combo

 

You can buy or make an elbow...Wilson makes some nice ones


I would drop the comp ratio down to 8-8.5:1 with some custom pistons and then get RealQuick (Jon) to make you some tubular hot parts around an Innovative turbo gt80R unit.Also ... you are most likely going to want to run a cam with a tighter LSA.

Im sure the others will chime in with ideas about Turbos and Cams....but thats a place to start.

 

That elbow is not what I was looking for.....but my buddy also rec. the same thing and to go to a 90mm TB. I will make everything here.....Not sure what turbo to go with.

Right now possibly a 76? or would that be too small?

The TB i have now is a 4 barrel type that looks like a carb.....I wish I could use it since I just bought it a year ago for $500

 

Power goals? That 76 will go a long ways.
Def less cam and less gear.

 

does your TB use a standerd air cleaner base?

you could use a carb hat ...something like this

what about a turbo from the GT40 family ? ....kinda big

 

That will work, it just uses the regular air cleaner


I'm not sure what power goals....as much as possible Put 3300# in the 8's

 

A GTS-76 should do it.. 1000hp can be had with the 76

..the GT40 series are 94mm...

 

o.k. I will look into it. This guy I am going to talk to in the morning about it. He will help me out with alot of it....I'm just trying to get a little more knowledgable and figure out what I need to do to get there

He has a 101mm

 

Not sure a 76 will get you in the 8's. I'm putting together a single 76mm kit right now for the street. Using RealQuick's hotparts which is a great kit for a good price.

A few reasons to go with a single turbo:

*Typically lower cost than buying two
*Typically lower underhood heat
*Typically easier to route pipe (less complexity/heat/weight??)


You'd need some dished forged pistons with maybe no more than 9:1 static. A fairly mid cam. Probably no more than 3:50 gears depending on tires/mph. A tuning solution (a fuel system that can deliver +0.55BSFC), MAF+modified stock PCM, 2-bar Speed density, stand alone engine management.

LS1tech has some good info on turbos and what can be had with a 76. Search here as well; I believe the consensus was that a good 76 could support 750-850rwhp and that an 88mm would be needed to hit 1000rwhp. Jose at ForcedInductions.com can help you out on selection.

Mostly opinions...Hope this helps

I think 88 is the way to go....
Waiting to here back from realquick.........I may just do all the fab work myself, I can fab it up with ease. I have DFI now. And will cc everything when the engine is apart and order a custom piston and camshaft.

 

I'd run 1 5/8 headers (1 3/4 max) for ~1000rwhp.

Run the biggest DP (downpipe/turbine exit) you can ie) 4"

mike, like i told ya last night, look at an S400 turbo, the T6 with like a 1.32 A/R will be fine for ya

 

a t88 or a s91 will get you your 8's. What kind of heads will you be using?
Is the car track only or do you drive it once in a while on the streets? You may want to go with a twins, a pair of t66's will do ya nice.
I assume your still going to use the 383 cubes you have now, your prolly not going to want that SR cam. Checkout forcedinductions.com

 

slomaro, he is going to keep the 383 and heads n such, and will change cam and pistons.

I believe the heads he is using are stock ported by eric bradby

 

I will keeps the heads, just get new pistons and a custom grind SR cam. And shaft mounts.

Its a track only car......10.50 tire
