What is a safe boost to run as far as having a daily driver? what type of turbo, Forged pistons, rods, and crank? a set of good flowing heads and cam? 6.0L or 5.7L block?? 4L60E or 4L80E? and where to get a good tuneup? GA

thanks
Ryan

BTW this will be going into a NP8 active 4WD s-10 pickup

9-10 lbs with a conservative tune and decent fuel should be fine on a stock bottom end. A stock 4L60E wont hold FI power levels.

I would run two turbos.. All things equal a quicker spool... Also lowers the spool point.... Cheap and simple would be a 6.0 iron block. I would also run a small camshaft. Run .63 a/r t3 turbine housings... These will be perfect for a 4WD powerband.. With the cam and turbo making power low enough we are'nt needing a stall converter at all.


Even a built NT LS could shred that transfer case.. I am running a NP205 gear drive in my rig...

NVG/NP tcase models have their tq capacities listed online...

I would get a built up 4l80E or 4l85E...

im not sure ill have enough room under the hood to run 2 turbos

V8_DSM_V8again

It takes up less space sometimes than a single turbo and a cross over pipe.

Look at the twin setups using truck manifolds...

Alot of ppl here have them.. They get mounted on with the outlet facing forward. The turbos mount high and up front... It will fit.. You might have to relocate the battery, coolant over flow or other things.. If it can fit in a F-body bay it can fit in a S-10..

sr_ryan1

thoses things look cheap what kind of boost could you get out of one of the .63 T3? who is running them on here?

V8_DSM_V8again

The whole .63 a/r T3 thing is just one part of a turbo.. That is the turbine/exhaust housing..

Thats like trying to pick a cam by looking only at exhaust lift or something... Not enough info...

A .63 A/R turbine housing is more restrictive than a .80 but perfect for a truck/true street rig..

Then there is the issue of different turbine wheels.. Different compressor wheels and compressor housings..

Let me know the cu in, desired RPM range and how much hp you want..

If you only want to run 10psi it will be completely different turbo than someone with the same engine that wants to run 25psi...

You need to give us a little more info to work with here. You mentioned street car. What power levels do you want? Are you wanting a new forged motor or the stocker? Are you looking for a pre-fabbed bolt on turbo kit or are you going to do all the fabbing yourself? You have to take all these things into consideration.

V8_DSM_V8again

He mentioned a forged shortblock...

He did leave out his desired power and if he could fab it or not...

Doing the reversed truck manis is pretty easy...

sr_ryan1

as much power as i can gain from a forged setup, so i guess my only limitaion will be the 4L80E trans. i would like to see at least 700# wrhp with all the cost that will be going into this. i thank wiht a low to mid range would be best.

V8_DSM_V8again

Twin GT30's... Efficient compressor wheel for pump gas pressure ratios.. (boost level.)

Forged pistons and rods vary in power capacity... A light weight forged will break before a heavier forging.... As in bigger beam dimensions... Oliver has like 8 different forged rod shapes for different types of racing as different engines need different designs..

Any way the twin GT30's will be alot of power but still very practical and wont suck if you set them to a low boost level untill you get a solid transmission...

Just get a 4l80e built by the same ppl that build the ones for the really fast f bodies that still run a 4 speed...

sr_ryan1

should i run flat top pistons? 220/220 cam? what kind of head gasket?

V8_DSM_V8again

FLAT TOP!!!!!!!!!!!!!

NO....

You will need dished...

For a head gasket a SCE ICS titan...

For a cam... Since its a daily driver..

Just a 206/212 on 112LSA ... Its a daily driver vehicle right. I am probaly going to use that cam in a TT 6.0 liter truck.. Cams have to be small on a turbo engine.. The HP difference between a small turbo cam and the biggest you could run is hardly anything compared to the HP spread that cams for a NA motor has..

It will spool faster and pull alot harder below the power curve with that cam... Its a truck right.... Well so is my project.. After looking at the calculations I would'nt hesitate to put that cam in even a TT vette if it were a daily driver... IT WORKS and does'nt need to be huge to do so.

You will see people spec out 114-116... But that is the 220/220 cams etc.. Thats because you need to go wider to avoid overalp with more duration...
