waht parts,upgrades will he need to go there safetely?
thanks

I would do

boost controller
full exhaust
power fc
intake
intercooler
1300 secondaries


but befor doing any of this, he needs to do his reliability mods

yes he is aware of the reliability mods, those are the mods that we have in mind about upgrades but intead of power fc he will be putting a microtech wit new wiring,and also we dont know if we can remove the rat nest and solenoids in the proces of non seq that will be a nice question also,
im doing a single conv in my car and i know i can remove all the solenoids and vacs because i wil install and ems, but in the case of the stock twins running non seq we exactly dont know if we can do the same.

thanks

stock twins non-seq. is the same as a single. You can remove all the sequential related solenoids. If he still has emmissions, he will need to keep those. if not, they can all go. The PRC (fuel pressure regulator control solenoid) is optional. I run without it. it only operates at startup.

you'll make the same power seq as you will non seq , just not as much down low with non-seq

TwinTurbo_SE7EN

not necessarily. I made more in the midrange non-sequential than I did sequential. There are other reasons though besides power for wanting to go non-sequential. ex: boost issues. I had a perfectly working sequential system and then it went to ****. I spent 8 months troubleshooting it...non-sequential has had me headache free since then.

if his sequential system is working properly, I would leave it alone.

Agreed. As far as mods would go, id say full exhaust, intake, upgraded IC, 1300cc secondarys, fuel pump, power fc, and ported wastegate is always nice to be safe. That should get you their no prob.

thanks for the help we have no emision control here so i asume we can remove all that crap out ,the sequentiall configuration is giving to much problems so it will be better to run non seq.
he plans to add micro tech with new wiring
ast alum
koyo rad
boost controller
full cat back
intercooler
Supra fuel pump
but we dont know what injectors size will be better he was thinking in upgrade injectors that can last later with the single wit more power
thanks again

if it's a microtech, it'll be easier on you if your secondaries aren't more than 50% larger than your primaries. ie: 550/1600 isn't a great idea. you'd be better off with 4 850's or 850/1000ish injectors.

you can get a haltech and have it control the sequentials if you want to keep some low end. you'll find it much easier to understand and maintain when you set it up yourself.

Just pay attention to your tuning. It's what matters the most.

thanks for the help again i think were a getting a good idea of what can we do and the parts needed for the task.
thanks
