expanding the 3sgte, time to upgrade! Options

[pittfirefighter]

OK so now that i finally have my 2nd gen 3sgte running right... its time to start with the upgrades...
Now what has already been done:

EGR eliminated
cold start eliminated
TVIS eliminated
custom side feed intake
2.5" intercooler piping with FMIC
Garrett T25 turbo
0.5mm oversized forged JE pistons
eagle forged rods
tial 38mm wastegate
3" custom exhaust
and many other little things
check my profile for full list..

SO as almost anyone with the 2nd gen... first thing that i absolutely wanted to change was the AFM... grrrrr i hate that thing
now there are basically three options:
1. 3rd gen ECU, someone at mr2oc.com sells a full kit to upgrade your stock wiring harness to fit the 3rd gen ECU, its $700 including ecu and new map sensor and much more
2. piggyback ecu (i looked into the Greddy E-manage)
3. full standalone EMS

**** important info on the greddy e-manage****
this thing is not made for the 3sgte... it causes nothing but trouble for it. I recently spoke with Dr. Tweak and he says to stay away as well. Not only is it built poorly for a Toyota engine (it can't interpret some of the ignition signals) but Greddy is also bankrupt so getting help for this thing is nearly impossible... stay away and you will be happy

so after some consideration.. my first upgrade in a string of upgrades is a giant jump but i think well worth it in the end...


let me know what you think!

i had a gt2871r, the oil feed line got pinched and the turbo ground the bearings down to bits and as you can imagine... destroyed... i have a t25 in there now that i had laying around just as a keeper since its the exact same exhaust side housing as the 52 trim that i had... til i get the 1300 for a new turbo... i am looking at a gt30 or i have seen the possibility of hopping up to a gt3582R...

355whp at 29 psi!? i dynoed at 305whp at 13 psi! and i should be pushing way over 350.... like i said... first step in a bunch of improvements

very true lagos... but one important fact is being overlooked in that assessment.... our flapper is toooo small for a larger turbo it creates a bottleneck and the turbo can't get the air it needs....

oh and if you're patient enough... the AEM only ran me a few hundred more than the 3rd gen ecu setup... including some extra sensors for the AEM
