i dont think i have a build thread here so i fighured i post some of it up here

this is round 2 for the remounted turbo setup and it last try. if this doesnt work out im doing a front mount f1x with a rece drive.
she had 115k on her and the diff and tranny showed every one of them. the diff sounded like a gear drive from a old v8 and the tranny pooped out of 2nd 3rd and 5th and was whineing pretty bad. so tore into her all the way in one shot insted of trying to pice it together over time as things failed.

things i have or are planing on/specs

5.3 iron block bored/stroked to 6.3

Nice way to start the year for RHMT, seeing LSX turbo builds on here.

You can't call it a rhmt kit unless it has rectangular piping in the mix. FUCK YEAH!

runsfromdacops · « **Reply #18 on:** January 14, 2013, 12:53:53 AM »

right now its on a stock pcm with hptuners. it may end up on the sock pcm with EFI live. we will see what the tuner whats to use for nog boost

runsfromdacops · « **Reply #21 on:** January 14, 2013, 09:26:01 PM »

and shes alive!!!! i got her running last night with vary little drama, a few little leaks and bs like that but nothing major.

took her on a 2 1/2 housr drive today and all seems to be good.

next step is getting her tuned which is what is proving to be the biggest pita. looks like theres no 3 bar OS for our ecus in hpt and i cant get a soild answer about if there is in EFI live or if i can do a ecu swap to a f-body one this can do a 3bar os and still have everything still work on the car

ratcityrex · « **Reply #22 on:** January 14, 2013, 10:58:02 PM »

That's Shitty about the 3 bar. Have u talked to any of the developers for hpt?

Joseph Davis · « **Reply #23 on:** January 15, 2013, 12:07:13 AM »

What year, what PCM number, and what reluctor tooth count on the crank?

runsfromdacops · « **Reply #24 on:** January 15, 2013, 12:28:08 AM »

the sticker on the ecu is all fed up. is there a way i can get the #with hpt?
the car is a 04 and the ecu has the 2 red/blue pulgs if that helps
24X relucter wheel

I don't see any reason why you can't run a 411 PCM like any other LS1 based car. Might be able to do a segment swap if there is special coding involved in the CTS-V for communicating with BCM/cluster. Can you pull the cover off of the top of the ECU, take a pic of the board? That would be the best way to determine for sure what will and will not run on your hardware.

Looks great, damn you work fast!

EG-MIKE · « **Reply #29 on:** January 15, 2013, 08:48:12 PM »

if this was mentioned, i missed it. have you looked into megasquirt for a bcm?

also, why did you choose to go with a twin rear mount setup? was space a deciding factor? i have so many questions haha. i cant wrap my mind around the awesomeness going on in this thread.

alot of the supra and rx7 guys i know usually convert from the stock twin turbo setup up to a huge single turbo setup, they say it helps control boost flow more evenly while getting higher HP obviously. do you see syncing the turbos to flow together for maximum HP being a problem?

i seen something similar to this on like horsepower tv years ago. they set it up on a newer camaro? i believe it was. the idea is sweet, but i would be way to worried having the turbo/s under the back of my car like that. probably because of the climate im in tho.
